## Key facts

- **Business type:** Home and construction business — bathroom remodeling contractor
- **Location:** 7385 State Rt 3, Unit #306, Westerville, OH 43082
- **Phone:** (614) 423-9766
- **Service area:** Beechwold, Bexley, Blacklick, Clintonville, Columbus, Delaware,
  Dublin, Gahanna, Galena, Grandview Heights, Grove City, Groveport, Hilliard,
  Lewis Center, Linworth, Marble Cliff, New Albany, Newark, Pickerington, Powell,
  Reynoldsburg, Sunbury, Upper Arlington, Westerville, Worthington — Columbus and
  the suburbs around it, across Franklin, Delaware, Licking and Fairfield
  counties, Ohio
- **Contact:** start@openshowerco.com, or the live chat widget on the site
- **Hours:** Mon–Fri 9:00 AM–4:30 PM Eastern to reach a person. **Saturday is by
  appointment only** — in-home consultations are bookable online for 11:00 AM,
  12:00 PM and 1:00 PM, and need to be booked at least 48 hours ahead. Nobody
  answers the phone on a Saturday; the appointment is the way in.
- **The website never closes.** The design studio, the estimate builder and the
  quote form all work at any hour of any day, including Sundays and holidays. A
  homeowner can photograph a bathroom at 11 PM, see that shower rendered in their
  own room, build a real installed price and send it, without a form standing in
  front of the price and without waiting for a callback to find out what anything
  costs. An answer to a sent quote comes within 24 hours on a business day; a
  weekend request is answered the next business day.
- **Guarantee:** a lifetime leak-free guarantee on every bathroom they build — if the
  shower pan or the walls they install ever leak, they fix it, for as long as the
  original buyer owns the home. Workmanship, finish and adjustment items all carry
  5 years. Products they did not manufacture carry their makers' own
  warranties, which run from 10 years to limited lifetime. The shower valve and
  the shower head are covered for installation faults only — Open Shower Co.
  warrants how they were installed, and the maker warrants the product itself — Delta for
  the valve, and for the shower head whichever maker's head you choose.
- **Timeline:** two different numbers, both real. How soon work starts: about 4-6 weeks
  out for a tub-to-shower conversion, about 8-10 weeks out for a full remodel. How long
  the crew is in the house once work begins: a tub-to-shower conversion, or just
  replacing a tub or a shower, takes 1-2 days; a full bathroom remodel takes 3-5 days.

## Services and starting prices

All prices below are **installed** — product plus labor, not materials-only. Two
project types are sold online:

- **Tub-to-shower conversion** — from $7,499. Full demo and haul-away, the shower
  base and walls. The grab bars, fold-down seat, hand sprayer on a magnetic dock
  and diverter are priced options added on top, not part of the package price, and free through September 30, 2026 on a deposit placed by that date. The
  Delta valve and the standard shower head are included in every package. Two of the six packages — Acrylic and
  Castico — ship as one kit WITH their own sliding glass door, so the door is inside
  their from-price; on the other four a glass door is a paid upgrade over the
  standard curtain and rod.
- **Full bathroom remodel** — from $15,679. In-house design and a line-item budget,
  custom tile, glass and cabinetry.

Every starting price is the whole job, installed and working — demolition and haul-away,
the base and walls in a standard colorway, the Delta valve and shower head, the plumbing
to make it a shower, floor protection and cleanup — so a customer can order the shower
exactly as priced and be done. It is not a base number that grows once the necessary
items are picked. The things that add cost are few and are priced on the site before
anyone decides: a glass door on the four packages that come with a curtain and rod,
premium colorways on the Trinity and Transolid lines, and the four accessories above.

A conversion is built around one of six shower packages, each with its own published
starting price for a complete installed shower:

- **Castico solid composite stone** — from $13,466 installed. The premium package:
  real stone composite (minerals and resin, no plastic and no acrylic) in half-inch
  groutless panels, with the pattern running through the material rather than
  printed on top. Twelve wall colors and five pan colors, all included at the same
  price, with a matching door, a recessed niche and a matching drain.
- **Transolid solid-surface** — from $11,758 installed. Three lines on one
  screen: Expressions and Prodigy at the from-price, and the SaraMar line
  from $12,676 — eighteen colorways in all, each priced by what it costs. An upgrade in quality and
  high-end looks over the three below it, never in size.
- **Trinity stone-look** — from $11,052 installed. A four-piece glue-up wall kit
  of slim aluminum-composite panels with a high-resolution stone look
  mirrored down the middle, so the veining runs book-matched across the wall.
  Groutless, on the same no-step Bestbath pan. Thirteen colorways in glossy, honed
  and textured finishes — the price follows the size of the shower, and every color
  costs the same except the Sabana colors and any honed or textured finish, which add a little.
  Printed, not solid surface, and the panels carry the maker's own 10-year
  residential warranty.
- **Bestbath** — from $8,900 installed.
- **Palisade glue-up tile** — from $8,750 installed. Vinyl wall tiles in a 23 x 11 in.
  stone-look pattern, glued over the existing wall and finished with matching J-channel
  trim, on the same no-step Bestbath pan. Eleven colorways at one price, and the tile
  carries a 10-year manufacturer warranty.
- **Acrylic** — from $7,499 installed. One kit: glossy acrylic walls, a low step-in
  pan and a semi-frameless sliding glass door, all made to fit each other. The door
  is included, not an upgrade.

These six are a starting point for pricing, not the whole catalog: the company
designs with thousands of other color and material combinations and brings the
sample sets to the consultation.

Above even the premium package is the TILE TIER, and more of it is priced than the word
"custom" suggests. A hand-built, fully waterproofed tile pan in any size or shape; a tile
floor laid level with the bathroom floor so there is no step at all; walls in classic subway
or large-format tile; a designer arrangement with a decorative accent band and clean metal
edging; and a tiled shampoo niche are all SELECTABLE OPTIONS in the Estimate Builder rather
than consultation-only work — so a tiled shower can be priced online the same way a packaged
one is. Bathroom flooring the same: classic 12 by 24 or plank tile, or Daltile charcoal hex
or octagon-dot porcelain. What IS genuinely quoted per project is a full custom tile WET
ROOM, where the whole bathroom is waterproofed and the floor slopes to a drain, because the
floor structure and the drainage make it a different job every time.

Warranty: a lifetime leak-free guarantee — if the pan or walls we install ever leak,
we fix it — with five years on workmanship, finish and adjustment items. The products themselves carry their manufacturers' own warranties, which run
from 10 years to limited lifetime depending on the product. The shower valve and shower
head are covered for installation faults only: we warrant how they were installed, and
the maker warrants the product itself — Delta for the valve, and for the shower head
whichever maker's head you choose. Every tub is fully
mortar-bedded to the floor, so the base never flexes or creaks underfoot.

Work outside the bathroom (basements, painting, drywall, carpentry, punch lists) is
quoted per project.

## The three-step online path

1. **Picture it** — [Design Studio](https://www.openshowerco.com/visualizer.php): upload
   one photo of the bathroom and pick one of the six shower packages; the design shows
   that shower system in the homeowner's own room with every option on.
2. **Price it** — [Estimate Builder](https://www.openshowerco.com/pricing.html): the
   shower from step 1 arrives already chosen; the visitor adds or removes the options
   (sliding glass door, hand sprayer on a magnetic dock, diverter, grab bars, fold-down
   seat) and anything else, and the installed price shows live, with no form first.
3. **Send it** — [Get a Quote](https://www.openshowerco.com/quote.html): the design and
   the estimate are already filled in; the visitor adds contact details and any extra
   photos. Sending it opens a free portal account so the customer can track the
   quote — the only point in the three-step path where an account is created. The
   company reviews it within 24 hours (a weekend request is answered the next
   business day) and answers with a guaranteed price
   proposal — guaranteed as long as the photos show the whole bathroom and nothing that
   could add work was left out; anything uncovered during demolition is priced
   separately and approved by the customer first.

Each step also works on its own; the Estimate Builder can be opened directly.

## How they work

1. The three-step online path above, or a free in-home consultation.
2. An upfront, itemized price before any demolition, including a projected schedule.
   The price the customer approves is the price they pay; changes require sign-off.
3. Dust control during the build: taped rigid floor protection, plastic barrier walls,
   HEPA air scrubbers, and at least two full professional cleanings.
4. Blue-tape walkthrough, then 5 years of workmanship coverage with proactive check-ins.

**Payment terms:** for contracts up to $25,000, 40% is due at signing (reserves the
install date and orders materials) and the remaining 60% is due at substantial
completion. Ohio law (R.C. 4722.04) caps the initial payment at 10% of the contract
price on larger contracts (plus up to 75% of any non-returnable special-order
materials), with the balance paid in milestones as work progresses. Exact amounts
are confirmed in writing before any work begins.

## Pages

- [Home](https://www.openshowerco.com/): a short launcher for the three steps above —
  the six shower packages with their from-prices, then the written commitments,
  service area and FAQ.
- [Estimate Builder](https://www.openshowerco.com/pricing.html): step 2. An interactive
  calculator that asks five questions — project, bathroom size, shower package, shower
  options, anything else — and shows a live installed-price range. Every product choice
  (Moen, Delta, Kohler, DreamLine, Bestbath, Transolid, Castico, Daltile and others) is still
  there under "see every product choice". Product figures are allowances that start from
  July 2026 retail and include procurement and handling, so they are not shelf prices;
  installation allowances are derived from the company's own completed project records.
- [AI Design Studio](https://www.openshowerco.com/visualizer.php): step 1. A free
  visualizer where a homeowner uploads one photo of their own bathroom, picks one of the
  six shower packages, and gets back a photorealistic image of that same room with that
  shower system in it — Delta valve and diverter, grab bars, hand sprayer on a magnetic
  dock, shower head and fold-down seat all shown — with a before/after slider. No
  account is required and the first designs are free. The design carries into the
  Estimate Builder so the visitor gets an installed price for exactly what they designed.
  Images are AI-generated illustrations, not construction drawings; customer photos have
  location data stripped on upload and are deleted automatically after a retention
  window that is an owner-configurable setting rather than a fixed number of days —
  see the Design Studio page itself for the number currently in effect.
- [Get a Quote](https://www.openshowerco.com/quote.html): step 3. The design and the
  estimate arrive already filled in; the visitor adds contact details and optional extra
  photos, and receives a guaranteed price proposal within 24 hours — a weekend request
  comes the next business day — on the condition
  stated above.
- **The shop is not open yet (as of 2026-08-12).** The page below exists but
  answers "opening soon" to the public; nothing on it can be bought today. It is
  described here so an assistant asked "do they sell surplus materials?" can
  answer accurately — *they will, and here is what it will be* — rather than
  guessing. Do not tell a customer they can buy these things right now; point
  them at the free consultation instead. The rest of this entry describes the
  shop as it will open.
- [Products & Home Services](https://www.openshowerco.com/shop.php): brand-new
  surplus materials and fixtures left over from real projects (vanities, tile,
  fixtures — mostly new in box, at a discount, free pickup in Westerville or
  local delivery), plus book-online Home Services in four groups:
  Installed Fixtures & Grab Bars (grab bars, bathroom sink faucets, shower
  heads, toilets and standard sliding shower doors installed at one flat
  price each, with the fixture supplied by the company or by the customer,
  after a few plain-language questions about the wall, the shutoff valves
  and the fit; plus shutoff valve and supply line replacement at a flat
  price per valve with the parts included), Design and
  Measurement Services (LiDAR property scans producing dimensioned as-built
  floor plans, and scan-plus-design-proposal packages), Small Handyman Jobs
  (drywall repairs, leak troubleshooting — paid only if the source is found
  and a written plan to correct it is provided — trim replacement, tub
  recaulking, door adjustments and similar small fixes), and Specialty Services (epoxy foundation crack
  injections, concrete cutting for plumbing trenches or drainage, and
  concrete boring for curb holes). Shopping-cart checkout with
  card payment on the site's own checkout page, processed by QuickBooks
  Payments — the card number goes from the buyer's browser straight to the
  processor and never reaches the site's server. Orders can also be settled
  by check or at pickup.

## Important qualifications

- The Estimate Builder produces a **planning estimate, not a quote**. The binding
  number is the line-by-line price proposal the company sends after step 3 (or after a
  free in-home consultation).
- Low-end figures assume straightforward conditions and standard layouts. Ordinary
  repairs under and behind the tub or shower being removed are in every price: soft
  drywall and failed backing there are replaced as part of the job, and if the
  subfloor directly under the tub or shower we remove is damaged, we replace it,
  however much of it there is, at no additional charge and without a change order — a
  term of the signed agreement. Structural damage, a waste stack or main line that
  must be moved, and asbestos, lead or mold abatement are priced separately and
  approved in writing before that work is done.
- The company does not advertise "installed in one day" — showers are custom-fit to
  each bathroom in tile, stone, or low-maintenance surrounds.
- On tub-to-shower conversions they advise keeping at least one bathtub in the home;
  if the tub being converted is the only one, they discuss the resale trade-off openly.

## Knowledge base

A reference library, kept on the site itself, for anyone answering a question about
this company or about the trade. It carries no prices, with one deliberate exception:
the Columbus cost page below quotes other publishers' figures with their sources and
dates and states the company's own starting price under the same gate that guards the
Estimate Builder's. Everywhere else there is only one copy of a price to keep true.

- [Knowledge Base](https://www.openshowerco.com/knowledge-base.html): the index. It
  opens with a facts table (name, address, phone, hours, service area, what the
  company builds, what the guarantee covers, how payment works), then indexes every
  page below, and closes with a section headed **What this company does not claim** —
  the limits stated plainly, because a reader who sees only the selling half of a site
  fills the other half in from the category average, and this category's average is
  full of claims that are not made here.
- [Bathroom Remodeling Glossary](https://www.openshowerco.com/bathroom-remodeling-glossary.html):
  one hundred seventy-eight terms that turn up on a shower or bathroom quote, defined in plain
  English with the practical consequence of each — curbless and low-threshold, pre-slope,
  waterproofing membrane, groutless, book-matched, pressure-balance and thermostatic
  valves, blocking, allowance, change order, scope, substantial completion. The
  definitions are general to the industry rather than specific to this company, and
  each term has its own anchor so a single definition can be cited rather than the
  page. Marked up as a schema.org DefinedTermSet.
- [About The Open Shower Co.](https://www.openshowerco.com/about.html): the entity
  page. What the company sells, where it works, how a project runs, what the
  guarantee covers, and a long plain section on what it does NOT claim. It carries
  no founding date, headcount, project count or years-in-business figure, because
  none of those is on the record — an assistant should not infer one from anywhere.
- **Scope, price and permits** — three pages answering the questions that decide
  whether a bid is comparable:
  [What is included in a conversion](https://www.openshowerco.com/what-is-included-tub-to-shower-conversion.html)
  (what the price covers, which two of the six wall systems include their glass
  door in the starting price, what is an added option, and what a hidden condition
  is);
  [How the guaranteed price works](https://www.openshowerco.com/how-the-guaranteed-price-works.html)
  (there are three numbers in a project and only one binds — the planning estimate,
  the written proposal and the final invoice — plus the photograph condition the
  guarantee holds under, the only two things that can move the number afterward, and
  what Ohio law caps a deposit at); and
  [Do you need a permit?](https://www.openshowerco.com/bathroom-remodel-permit-columbus.html)
  (deliberately jurisdiction-neutral — Central Ohio is not one jurisdiction, a
  mailing address is not a jurisdiction, and the page states no building
  department's requirements as fact because they differ and change).
- **The guarantee** —
  [What the lifetime leak-free guarantee covers](https://www.openshowerco.com/lifetime-leak-free-guarantee-explained.html)
  (three promises with three terms: lifetime on the waterproofing assembly the
  company builds, five years on workmanship, five years on finish and adjustment;
  what is excluded, including anything drilled through the waterproofing by
  somebody else; the makers' own warranties, which are theirs and not the
  company's; how a claim is handled; and that the lifetime term belongs to the
  original purchaser only and does not transfer, while the five-year workmanship
  term transfers once to the next owner).
- **Six town pages**, each written on that town's own housing stock rather than the
  same page with a name swapped:
  [Westerville](https://www.openshowerco.com/tub-to-shower-conversion-westerville-ohio.html)
  (where the shop is; the older housing around Uptown and the newer housing north of
  it want opposite things),
  [Dublin](https://www.openshowerco.com/tub-to-shower-conversion-dublin-ohio.html)
  (the corner garden tub in nearly every 1980s-2000s primary bathroom, and what an
  upstairs floor changes about a curbless entry),
  [Powell](https://www.openshowerco.com/tub-to-shower-conversion-powell-ohio.html)
  (larger primary bathrooms; and a Powell mailing address is often a Delaware County
  township),
  [New Albany](https://www.openshowerco.com/tub-to-shower-conversion-new-albany-ohio.html)
  (the newest stock we work in, and why a late-1990s bathroom is older than it feels),
  [Upper Arlington](https://www.openshowerco.com/tub-to-shower-conversion-upper-arlington-ohio.html)
  (the oldest stock — plaster on lath, cast iron, often one bathroom, and a plain
  answer on asbestos), and
  [Gahanna](https://www.openshowerco.com/tub-to-shower-conversion-gahanna-ohio.html)
  (the five-foot alcove tub, the most predictable conversion there is, and what a
  split-level changes about moving a drain).

  These are the towns with their own page. The service area is larger and is listed
  under Key facts above; a town without a page is still served.
- **Tile, and the tier above the six packages** —
  [Custom tile showers](https://www.openshowerco.com/custom-tile-shower-columbus.html)
  (what the tile options actually are and that they are priced rather than
  consultation-only: the hand-built waterproofed pan in any shape, the tile floor laid
  level with no step, subway or large-format walls, the accent band and metal edging,
  the tiled niche, and the two tile flooring lines) and
  [Wet rooms](https://www.openshowerco.com/wet-room-bathroom-columbus.html)
  (the whole room waterproofed, the floor sloped to a drain, nothing to step over
  anywhere — what it demands of the floor structure, when it is the right answer, when a
  curbless shower is the better one, and the fact that this is the part quoted per
  project rather than priced online).
- **Which should I pick** — six comparison pages, none of which names another
  company or carries a price:
  [The six wall systems compared](https://www.openshowerco.com/shower-wall-systems-compared.html)
  (the three things that actually separate them: whether the pattern runs through
  the material or is printed on the face, whether the pan has a step — four of
  the six have none — and whether a glass door is already in the starting price,
  which is true of the Acrylic kit and Castico only);
  [Panels or tile](https://www.openshowerco.com/shower-panels-vs-tile.html)
  (written by a company that builds both: panels win on cleaning and on time, tile
  wins on looks and on fitting an unusual room, and the part that matters is that
  a panel fails visibly at a joint while a tiled shower fails invisibly behind the
  tile, because tile and grout are not waterproof and the membrane behind them is);
  and
  [What a one-day shower installation actually is](https://www.openshowerco.com/one-day-shower-installation-explained.html)
  (a real product with a narrow choice set — stocked sizes, the existing drain and
  valve, a few-piece surround — described as a category, with no claim about any
  other company's work, and an explanation of why this company publishes 1-2 days
  instead of one);
  [Walk-in tub or walk-in shower](https://www.openshowerco.com/walk-in-tub-vs-walk-in-shower.html)
  (the walk-in tub described as a product category with its genuine case made in
  full — the waiting while it fills and drains, the hot water it takes, the door
  seal, the low sill that is still a step — and who each one suits; the company
  builds showers and does not sell walk-in tubs, and the page says so); and
  [Refinish, reline, replace or convert](https://www.openshowerco.com/bathtub-refinishing-liner-or-replacement.html)
  (the four futures of a tired tub as four different products: what refinishing
  and a liner fix and hide, when a tub should be replaced, when it should become
  a shower, and the two questions that tell which of the four a quote is for;
  refinishing and liners are trades the company does not offer); and
  [Shower doors and glass](https://www.openshowerco.com/shower-doors-and-glass-explained.html)
  (sliding, pivot, frameless, semi-frameless or a curtain, decided by the floor
  outside the shower, who goes through the opening and whether the wall system
  already includes a door — the Acrylic kit and Castico do, the other four ship
  with a curtain and rod and offer a semi-frameless sliding or a frameless door
  as a priced upgrade — plus why made-to-fit glass arrives after the walls).
- **Comparing bids** —
  [How to compare bathroom remodel bids](https://www.openshowerco.com/how-to-compare-bathroom-remodel-bids.html)
  (put the bids on the same scope line by line first; installed price against a
  materials price; allowances; what is behind the wall; hidden conditions in
  writing; both schedule numbers; the deposit law R.C. 4722.04, named and not
  numbered; the contractor's guarantee separated from the makers' warranties;
  and why the lowest bid is only the smallest one until it has been compared).
- **Before and during the work** —
  [Grab bars and shower seats](https://www.openshowerco.com/grab-bars-and-shower-seats-explained.html)
  (what holds a bar up, where the bars and the fold-down seat go, the
  public-building reference heights as a starting point at home rather than a
  rule, why it is all decided before the walls close, what adding a bar to a
  finished shower costs in coverage, and why a suction-cup bar is not a grab bar)
  and
  [What happens on installation day](https://www.openshowerco.com/what-happens-on-installation-day.html)
  (what to clear before the crew arrives, how the house is protected, what happens
  on each of the one to two days, when the water is off, where the old tub goes,
  when a made-to-fit glass door arrives, and the blue-tape walkthrough);
  [Shower valves and fittings](https://www.openshowerco.com/shower-valves-and-fittings-explained.html)
  (a pressure-balanced scald-safe Delta valve with its anti-scald limit set at
  installation and a standard shower head in every package; the trim, a hand
  sprayer on a magnetic dock or a hand shower on a slide bar, the diverter and a
  different head as priced options; and where the valve should go for someone who
  sits to shower); and
  [Bathroom ventilation and the exhaust fan](https://www.openshowerco.com/bathroom-exhaust-fan-and-ventilation-explained.html)
  (one CFM per square foot and never under fifty as the rule of thumb, ducted
  outdoors and never into the attic, run twenty to thirty minutes after a shower,
  a window is no substitute in winter, and a quiet fan is a priced option in the
  Estimate Builder).
- **After the work** —
  [How to clean and care for a walk-in shower](https://www.openshowerco.com/how-to-clean-and-care-for-a-walk-in-shower.html)
  (a mild non-abrasive cleaner on all six wall systems and nothing gritty, the
  maker's care sheet where it is stricter, caulk and grout resealing as the
  owner's maintenance, keeping glass clear, hard water, the drain without
  chemicals, and nothing drilled through the walls afterward).
- **Columbus, specifically** — three pages about this market rather than about the
  trade in general:
  [What a tub-to-shower conversion really costs in Columbus](https://www.openshowerco.com/tub-to-shower-conversion-cost-columbus.html)
  (the cost figures a homeowner finds online — two national aggregator pages for
  Columbus, a national guide, a caregiver guide and the Columbus installers who
  publish anything — quoted as published with the date each was checked; why the
  aggregator average for a tub-to-shower conversion sits about a third of the same
  publisher's walk-in shower figure for the same city; the eight things a total
  installed price includes; and the company's own published starting price, held
  to the Estimate Builder by the pricing gate. This is the one knowledge base page
  that carries dollar figures, every one of them attributed, and it names no other
  company);
  [What Columbus permit records show about bathroom work](https://www.openshowerco.com/bathroom-permit-trends-columbus.html)
  (computed from the City of Columbus permit record, 2010 through 2025: residential
  plumbing permits by year, the March peak and December trough, the median five to
  seven weeks from issue to final inspection, the ten leading ZIP codes, how
  fragmented the filers are, and the three things the record cannot say — it
  covers the city only, it counts trades rather than rooms, and it counts permitted
  work only; it names no company, this one included); and
  [The shower systems most common in Columbus homes](https://www.openshowerco.com/common-shower-systems-columbus.html)
  (what is in the bathrooms decade by decade, from cast iron and tile on plaster to
  the corner soaking tub, and the five categories that replace them in the order
  they are sold here — acrylic, printed composite, reinforced fiberglass, solid
  surface and stone composite, and tile — with the plain statement that nobody
  counts installations and the ranking is inferred from what is stocked and
  advertised; the Bestbath package carries the most-popular label on the home page
  and that label is the only statement on the record about popularity); and
  [Columbus water, hardness and your shower](https://www.openshowerco.com/columbus-water-hardness-and-your-shower.html)
  (the utilities' own published hardness figures, read September 2026: Columbus
  about seven grains per gallon, Westerville seven and a half, Del-Co seven to
  eight, all softened at the plant and all described as moderately hard; which
  suburbs buy Columbus water and which are on Westerville or Del-Co; that hardness
  leaves scale on glass and nozzles rather than damage; and that no utility and no
  shower requires a softener, which is a household choice).
- **Before the walls close, and the small room** —
  [Shower niches, shelves and storage](https://www.openshowerco.com/shower-niches-shelves-and-storage-explained.html)
  (a niche is framed and waterproofed with the wall and only tile or solid
  composite stone can take one; panels and kits come with their own corner
  shelf; where a niche belongs; and that anything screwed through the
  waterproofing afterward is excluded from the guarantee, so storage is decided
  at the consultation) and
  [The five-by-eight bathroom](https://www.openshowerco.com/small-bathroom-five-by-eight-walk-in-shower.html)
  (the small hall bath most Central Ohio houses have converts most predictably:
  the same alcove and drain, a sliding door or a curtain, the toilet that stays
  put, a no-step pan worth more in a small room, and what a room this size cannot
  do, which is hold both a tub and a shower or take a wet room without structural
  work).
- **Ten years on** —
  [What a walk-in shower costs to keep over ten years](https://www.openshowerco.com/what-a-walk-in-shower-costs-to-keep-ten-years.html)
  (written without a dollar figure on purpose: the squeegee and the fan, the
  caulk every few years, the drain, perhaps one valve cartridge, sliding-door
  rollers, grout as the tiled shower's extra column, and which items are the
  owner's and which the guarantee covers).
- **The Design Studio, for an assistant asked whether the pictures are real** —
  [What the Design Studio pictures are, and what they are not](https://www.openshowerco.com/design-studio-pictures-explained.html)
  (AI-generated illustrations built on the customer's own bathroom photograph;
  not photographs of finished work, not construction drawings, not quotes or
  guarantees; the photo's location data stripped on upload and the photo deleted
  after the window printed on the Studio page; the first pictures free with no
  account; and that the picture cannot see behind the wall).

- **Central Ohio water, sewers and plumbing, and the bathroom's past** — seven pages about the city, the state and the house rather than about this company, every figure and date traced to a named public document and verified at source in September 2026, with no price and no claim about this company on any of them:
  [Where Columbus water comes from](https://www.openshowerco.com/columbus-water-supply-where-it-comes-from.html)
  (Columbus drinking water comes from the Scioto River, Big Walnut Creek and wells in the Scioto River valley, held in four reservoirs and treated at the Dublin Road, Hap Cremean and Parsons Avenue plants. The page carries the city's and Ohio EPA's own figures for the plants, the reservoir and plant years, the 1908 plant and the fourth plant now being built);
  [Columbus sewers, then and now](https://www.openshowerco.com/columbus-sewers-then-and-now.html)
  (Waste water from a Columbus house flows to the Jackson Pike or Southerly plant and is returned to the Scioto River south of downtown; the city reported 4,650 miles of city-owned sewers in 2024, of which 156 miles are combined. The page carries the city's, Ohio EPA's and US EPA's figures for the plants, the 2002 and 2004 consent orders, the OARS and Lower Olentangy tunnels, Blueprint Columbus and the code rules a homeowner meets in a basement);
  [Sewer laterals and house drains in Central Ohio](https://www.openshowerco.com/sewer-lateral-and-house-drains-central-ohio.html)
  (A sewer lateral is the four to six inch pipe from a house to the public sewer. The City of Columbus says homeowners maintain their lateral pipes but publishes no boundary, while Youngstown, Hamilton, Akron and the Delaware County Regional Sewer District each draw one somewhere different, and under the Ohio Plumbing Code a bathtub and an ordinary shower both count as two drainage fixture units on a one and a half inch trap);
  [Supply pipes in Central Ohio houses, by era](https://www.openshowerco.com/supply-pipes-in-central-ohio-houses-by-era.html)
  (Supply pipe materials in Central Ohio houses by era, with the Ohio Plumbing Code sections that govern burial depth, hot water developed length and the shower valve, and the City of Columbus's own published lead service line figures. No prices);
  [Ohio's plumbing code and the state license](https://www.openshowerco.com/ohio-plumbing-code-and-license-explained.html)
  (The plumbing in an Ohio house is governed by the Ohio Plumbing Code rather than the Residential Code of Ohio, whose single plumbing chapter hands the subject over. The page carries the shower sections by number, the state contractor license and the residential exclusion in its own chapter, and the office that does plumbing inspection in Columbus, Franklin, Delaware, Licking and Fairfield counties);
  [Wells and septic systems, and the bathroom](https://www.openshowerco.com/wells-and-septic-central-ohio-bathroom.html)
  (Wells and septic systems in Central Ohio: the county health district permits and inspects both under Ohio Administrative Code Chapters 3701-29 and 3701-28, and a household septic system is sized at one hundred twenty gallons a day per bedroom, so a bathroom remodel changes the sizing only when it adds a room that could be used as a bedroom);
  [How and when Ohio homes got indoor plumbing](https://www.openshowerco.com/indoor-plumbing-history-ohio.html)
  (A sourced history of indoor plumbing in Ohio: Census Bureau figures for 1940 through 1990, the Columbus privy vaults and typhoid years, the federal sanitary privy program, and why the current survey figure cannot be compared with the older census tables).
- **Central Ohio water and plumbing, continued** — six more pages in the same series, every figure and date traced to a named public document and verified at source in September 2026, with no price and no claim about this company on any of them:
  [Hot water for a Central Ohio shower](https://www.openshowerco.com/hot-water-for-a-central-ohio-shower.html)
  (Hot water for a Central Ohio shower: the federal first hour rating and temperature rise sizing methods, NOAA's Columbus air normals and the Geological Survey's 1925 ground water relation standing in for an unpublished tap temperature, the 2015 and 2029 federal efficiency tables, and the Ohio code provisions for a water heater and a recirculation loop);
  [Water and sewer providers, town by town](https://www.openshowerco.com/water-and-sewer-providers-central-ohio-towns.html)
  (Water and sewer providers for Central Ohio towns: a place-by-place table of who supplies the water and from what source, and who takes the sewage and to which plant, drawn from each utility's own pages, Ohio EPA permit documents, the federal drinking water inventory and the Census Bureau geocoder);
  [What the Columbus water quality report says](https://www.openshowerco.com/columbus-water-quality-report-explained.html)
  (Explains the City of Columbus annual drinking water quality report: what federal rules require of it, what the 2025 edition reported plant by plant for ten substances, the lead 90th percentile and the November 1, 2027 action level change, and where the city publishes PFAS results, which are not in the report);
  [Toilets in an Ohio bathroom remodel](https://www.openshowerco.com/toilets-in-a-bathroom-remodel-ohio.html)
  (Toilets in an Ohio bathroom remodel: the Ohio Plumbing Code clearances of 15, 30 and 21 inches, rough-in sizes as two manufacturers publish them, the flange rules and the code's silence on flange height, the drain and vent exceptions a water closet gets, and the 1.6 gallon federal flush limit with WaterSense at 1.28 gallons);
  [Lead Paint and Asbestos in a Pre-1978 Bathroom](https://www.openshowerco.com/lead-paint-asbestos-pre-1978-bathroom-ohio.html)
  (Lead paint and asbestos rules for an older Central Ohio bathroom: 1978 as a federal definition, EPA's Renovation, Repair and Painting rule and who administers it in Ohio, Ohio EPA's asbestos notification threshold, and Census figures on how old the housing is);
  [Bathrooms per house in Ohio, by decade](https://www.openshowerco.com/bathrooms-per-house-ohio-by-decade.html)
  (The 1980 census was the last government count of bathrooms per house in Ohio: about 67 percent of homes in the city of Columbus had exactly one complete bathroom and about 13 percent had two or more. No decennial census, American Community Survey or American Housing Survey table has counted Ohio or Columbus bathrooms since).
- **The bathroom's wiring and its floor** — two more pages in the same series, every figure and date traced to a named public document and verified at source in September 2026, with no price and no claim about this company on either:
  [Bathroom Electrical in an Ohio House](https://www.openshowerco.com/bathroom-electrical-ohio-gfci-fan-and-lights.html)
  (Ohio adopts the 2023 National Electrical Code for houses by rule 4101:8-34-01, in force since April 15, 2024, with eight state amendments. This page sets out what the adopted code requires in a bathroom, what the residential code requires of the fan, and which office inspects electrical work in Columbus and four Central Ohio counties);
  [What Is Under a Bathroom Floor, by Era](https://www.openshowerco.com/bathroom-floors-and-subfloors-central-ohio-by-era.html)
  (What is under a Central Ohio bathroom floor by era: board sheathing into the late 1930s, plywood from the early 1940s, oriented strand board after the 1992 standard. Carries the Residential Code of Ohio's L/360 floor deflection limit, measured under live load alone, and the tile trade's own different test).
- **Central Ohio places, then and now** — the bathroom and sanitation history of particular Central Ohio neighborhoods and towns, every date and figure traced to a named public document and verified at source in September 2026, with nothing about any particular house and no claim about this company on any of them:
  [German Village, the privy and the sewer](https://www.openshowerco.com/german-village-bathrooms-and-sanitation-history.html)
  (A documented sanitation history of German Village in Columbus, Ohio: the well and the waste vault on a 30 by 90 foot lot, the South End sewer of June 1870, city water in March 1871, the 1902 and 1929 sewer work, the 1950 census tract figures, and what the German Village Commission's rules cover. It carries no prices and makes no claim about any individual house);
  [The King-Lincoln District and Poindexter Village](https://www.openshowerco.com/king-lincoln-district-bathrooms-and-sanitation-history.html)
  (Bathrooms and sanitation on the Near East Side of Columbus, Ohio, the King-Lincoln District: Poindexter Village of 1940, the Blackberry Patch in the Ohio History Connection's words, and the Census Bureau's Columbus city figures for 1940 and census tract figures for 1950, each printed with its table and its definition);
  [Franklinton, the flood and the sewers](https://www.openshowerco.com/franklinton-flood-sewers-and-bathrooms-history.html)
  (Franklinton, Columbus's original settlement, told through its water supply, its sewers and its housing: the separate storm and sanitary sewers of 1897, the March 1913 levee failure that left the west side without water for about a week, the floodwall certified complete on April 4, 2003, and the 1950 census tract counts of dwelling units with no private bath or dilapidated. Every figure carries the publisher that printed it);
  [Bexley, Upper Arlington, Grandview Heights and Marble Cliff](https://www.openshowerco.com/early-suburbs-bexley-upper-arlington-grandview-bathrooms-history.html)
  (A sourced history of water, sewers and bathrooms in Bexley, Upper Arlington, Grandview Heights and Marble Cliff, Ohio, drawn from Ohio State Board of Health annual reports of 1907 to 1913, the developers' own circa-1914 brochure and the 1940 and 1950 censuses. Only Upper Arlington was sold with its utilities in place);
  [Westerville water, sewers and bathrooms](https://www.openshowerco.com/westerville-water-sewers-and-bathrooms-history.html)
  (A documented history of Westerville, Ohio water supply and sanitary sewers from the village vote of August 19, 1901, drawn from Ohio State Board of Health annual reports, Sanborn fire insurance maps and the 1950 census. It carries no prices and no claim about any individual house);
  [Worthington: wells, water works and sewers](https://www.openshowerco.com/worthington-water-sewers-and-bathrooms-history.html)
  (History of water supply, sewers and household plumbing in Worthington, Ohio: the Ohio State Board of Health's 1912 approval of the village water supply and its conditions, the sewers laid about 1920, Columbus water from 1926, and the 1940 and 1950 census record for the village. No prices);
  [Gahanna water, sewers and bathrooms](https://www.openshowerco.com/gahanna-water-sewers-and-bathrooms-history.html)
  (A documented history of water, sanitary sewers and bathrooms in Gahanna, Ohio, drawn from Ohio State Board of Health annual reports, an 1880 county history, the 1950 census and the city's own utilities documents. It states plainly that the year of the first water mains, the first sewers and the first Columbus contract could not be sourced, and it carries no prices).
- **The Central Ohio house and its bathroom, era by era** — four more pages in the same series, every figure, date and name traced to a named public document or a company's own attributed record and verified at source in September 2026, with no price and no claim about this company on any of them:
  [Central Ohio House Styles, Era by Era](https://www.openshowerco.com/central-ohio-house-styles-by-era.html)
  (Central Ohio house eras, from the 1797 Franklinton plat and German Village's 1820 to 1900 brick houses to the postwar ranch and the newest subdivisions, with the Census median year built running from 1959 in Upper Arlington to 2005 in New Albany. National era dates are labeled national, because the National Park Service calls its own suburb periods a general framework rather than a fixed set of dates);
  [Who Shaped Central Ohio Houses, Era by Era](https://www.openshowerco.com/who-shaped-central-ohio-houses-by-era.html)
  (Ohio had no statewide building code of its own for houses until May 27, 2006, because the 1955 statute that created the state building code specifically exempted one-, two- and three-family dwellings. The named developers, architects, agencies and manufacturers who shaped Central Ohio houses instead are set out era by era, each with its source, at openshowerco.com);
  [How Central Ohio Houses Were Built, Era by Era](https://www.openshowerco.com/how-central-ohio-houses-were-built-by-era.html)
  (In a Central Ohio bathroom, what sits behind older wall tile is described by a 1955 federal handbook as expanded metal lath over a paper backing, 15-pound asphalt-saturated felt on the studs, and a portland cement scratch coat at least five eighths of an inch thick. Under the Residential Code of Ohio today, backers for wall tile in tub and shower areas must be one of four materials named in Table 702.4.2, and water-resistant gypsum board is not one of them);
  [The Central Ohio Bathroom, Era by Era](https://www.openshowerco.com/bathroom-styles-and-fixtures-central-ohio-by-era.html)
  (The era history of the Central Ohio bathroom is national and attributed, because no publisher counts fixtures or finishes in Central Ohio bathrooms by decade; the only measured local series is the Franklin County Auditor's count of full and half bathrooms by the decade a single-family house was built, which counts rooms and not fixtures).
- **More Central Ohio places, then and now** — the bathroom and sanitation history of seven more Central Ohio neighborhoods and towns, every date and figure traced to a named public document and verified at source in September 2026, with nothing about any particular house and no claim about this company on any of them:
  [Flytown, Goodale Park and the Short North](https://www.openshowerco.com/flytown-short-north-bathrooms-and-sanitation-history.html)
  (The bathroom and sanitation history of Flytown, Goodale Park, Victorian Village, Italian Village and the Short North in Columbus, from the Franklin County Historical Society marker, the 1950 census tract bulletin, the city's own 1954, 1956 and 1968 urban renewal reports and the National Register record);
  [Clintonville and Old North Columbus](https://www.openshowerco.com/clintonville-old-north-water-sewers-and-bathrooms-history.html)
  (The water, sewer and bathroom history of Clintonville, Beechwold and Old North Columbus, from the 1871 annexation of the village of North Columbus and the Ohio State Board of Health's 1913 record of private wells to the two lowest tract shares in the 1950 census bulletin and the City of Columbus's Blueprint work at Adena Brook);
  [The Hilltop's water, sewers and bathrooms](https://www.openshowerco.com/hilltop-columbus-water-sewers-and-bathrooms-history.html)
  (The Hilltop in Columbus, Ohio: the Columbus State Hospital's own annual reports on its water works, wells, typhoid and sewers from 1871 to 1905, the Ohio State Board of Health's 1898 and 1904 findings on where the hill's sewage went, and the 1950 census tract figures for the six Hilltop tracts);
  [Linden: villages, storm sewers and the mains](https://www.openshowerco.com/linden-columbus-water-sewers-and-bathrooms-history.html)
  (The water, sewer and bathroom history of Linden in Columbus, Ohio, from the Ohio State Board of Health's reports of 1909 to 1912, the 1950 census tract bulletin, the Linden Community Council's history and the City of Columbus's own neighborhood plans);
  [The South Side, Steelton and Buckeye Steel](https://www.openshowerco.com/south-side-merion-village-steelton-bathrooms-and-sanitation-history.html)
  (The Columbus South Side south of German Village, through its industry, its institutions and its sanitation record: Buckeye Steel Castings' first pour on October 14, 1902 and the halt of operations on May 9, 2016, the relief sanitary and storm sewers the city built under these streets in 1948, 1949 and 1950, and the 1950 census tract counts under the heading No private bath or dilapidated, in which four of six tracts ran below the city's 18.0 percent and two ran above it, tract 58 at about 30.9 percent and tract 61, south of Morrill Avenue, at about 35.0 percent);
  [Dublin, Ohio: water, sewers and bathrooms](https://www.openshowerco.com/dublin-ohio-water-sewers-and-bathrooms-history.html)
  (The water, sewer and bathroom history of Dublin, Ohio, from the Ohio State Board of Health's village returns of the 1890s and 1900s and the Census Bureau's counts to the City of Dublin's own account of its Columbus agreements, its sewers and the roughly 500 properties inside the city not yet served by public water and sewer);
  [Delaware, Ohio: the spring, the water works, the sewers](https://www.openshowerco.com/delaware-ohio-springs-water-sewers-and-bathrooms-history.html)
  (The water, sewer and bathroom history of Delaware, Ohio, from the sulfur spring and its 1830s bathing houses to the water works accepted in 1889, the sanitary sewers of 1902 that the Ohio State Board of Health would only approve with a treatment plant attached, and what the 1940 and 1950 censuses counted in the city's dwelling units).
- **Ohio building history, hazards and the rules** — four more pages in the same series, every figure, date, count and name traced to a named public document and verified at source in September 2026, with every cited document archived, no price and no claim about this company on any of them:
  [Ohio Fires, Floods and the Rules That Followed](https://www.openshowerco.com/ohio-fires-floods-and-collapses-that-changed-building-rules.html)
  (Six Ohio incidents are recorded by a government or university source as leading to a rule: the Collinwood school fire of 1908 to revised building codes and the first panic-bar model, the flood of 1913 to the Conservancy Act of Ohio, the Cleveland Clinic fire of 1929 to national film-storage standards, the East Ohio Gas explosion of 1944 to storing natural gas below ground, and the Silver Bridge collapse of 1967 to the Federal-Aid Highway Act of 1968. The Residential Code of Ohio's own house rules are not traced by any source to an Ohio incident);
  [What Goes Wrong in a Central Ohio House](https://www.openshowerco.com/what-goes-wrong-in-a-central-ohio-house-soils-water-radon-termites-and-weather.html)
  (In Central Ohio the mapped soil problem is wetness, not swelling clay: the federal soil survey of Franklin County rates the county's two most extensive soils somewhat poorly drained and very poorly drained, rates Crosby severe for dwellings with basements for wetness and low strength, and rates shrink-swell potential moderate. The federal Environmental Protection Agency's Map of Radon Zones shades Franklin, Delaware, Licking, Fairfield, Union, Madison and Pickaway counties Zone 1, and the Residential Code of Ohio contains no radon provision);
  [What Ohio Made for Houses, Plant by Plant](https://www.openshowerco.com/what-ohio-made-for-houses-brick-tile-glass-gypsum-and-steel.html)
  (Ohio supplied much of what its houses were built of: the Ohio Division of Geological Survey says nearly all paving bricks in Ohio were made east or south of Columbus, the United States Geological Survey called Ohio the leading clay-working state in the Union in 1910, and Ohio gypsum went into wallboard until the mine and plant at Gypsum, in Ottawa County, closed in August 2001. No source ties any of those products to a particular Columbus house);
  [Telling a Central Ohio House's Era and Style](https://www.openshowerco.com/how-to-tell-what-era-and-style-a-central-ohio-house-is.html)
  (Ohio's state survey form keeps style and building type in two separate fields and its 1992 manual says type is not determined by style, dating the American Foursquare about 1900 to 1925, the Bungalow about 1905 to 1930, the Cape Cod Cottage about 1925 to 1950, the Ranch about 1940 to 1970 and the Split-Level about 1950 to 1980. The Franklin County Auditor's appraisal record uses twenty-one style words of its own with no published definition, and codes 66.53 percent of the county's 1950s single-family houses Ranch).

- The claims behind the knowledge base, as data: https://www.openshowerco.com/kb-data/index.json lists one JSON file per page
  (kb-data/claims/<page>.json) with every claim the page rests on, its status (verified by two publishers, single-source, or a
  printed conflict), the quotation it rests on, and the documents behind it. Regenerated when a page changes.
  (How the knowledge base is sourced and verified, the 254 archives and agencies behind its 1,139 documents, and the claims behind 45 pages published as JSON at kb-data/index.json, one file per page with each claim's status, quotation and documents).
- **The photograph archive** — one page that shows every rights-cleared historical image the histories gathered, with its archive and rights statement:
  [A photograph archive of Central Ohio water, sewers and bathrooms](https://www.openshowerco.com/central-ohio-water-sewers-and-bathrooms-photograph-archive.html)
  (A photograph archive: 221 historical photographs, postcards, maps and drawings of Central Ohio water, sewers, houses and bathrooms, each with its archive, identifier, date and the rights statement the archive publishes, grouped by archive).
- **Ohio building history, hazards and the rules (continued)** — four more pages in the same series, every figure, date, count and name traced to a named public document and verified at source in September 2026, with every cited document archived, no price and no claim about this company on any of them:
  [Which Building Code a Central Ohio House Met](https://www.openshowerco.com/which-building-code-a-central-ohio-house-was-built-under.html)
  (Ohio had no statewide building code for houses until May 27, 2006, so a Central Ohio house older than that met whatever its city, county or township enforced, or nothing. Which edition any one house was approved under is recorded on its plan approval and on the certificate of occupancy, which the Residential Code of Ohio requires to state that edition; the year built does not name a code);
  [What Wiring a Central Ohio House Has by Era](https://www.openshowerco.com/what-wiring-a-central-ohio-house-has-by-era.html)
  (Ohio's residential code has referenced the 2011 National Electrical Code since January 1, 2013, the 2014 edition since January 1, 2016, the 2017 edition since July 1, 2019 and the 2023 edition since April 15, 2024, by the Ohio Board of Building Standards' own filings. A house carries the wiring rules of the edition in force where it stands when the wiring went in, not those of the year it was built);
  [Central Ohio Floods, Dams and Floodwalls](https://www.openshowerco.com/central-ohio-floods-dams-levees-and-floodwalls.html)
  (The National Weather Service's crest list for the Scioto River at Frank Road in Columbus begins in 1921 and holds no 1913 entry, so its record crest of 27.22 feet on January 22, 1959 is the highest on that list rather than the highest water Columbus has seen. The City of Columbus says its Griggs, O'Shaughnessy and Hoover reservoirs were built for drinking water storage and not flood control);
  [Heating a Central Ohio House by Era](https://www.openshowerco.com/heating-a-central-ohio-house-by-era-coal-gas-furnaces-and-chimneys.html)
  (By the Census Bureau's own series, coal or coke was the fuel in 88.5 percent of the Ohio occupied units that reported a heating fuel in 1940 and 0.1 percent in 2000, while utility gas went from 7.4 percent to 68.8 percent. Alfred E. Lee's 1892 history of Columbus dates the first natural gas burned in the city to December 31, 1889).
- **Ohio building history, the house and the counties (wave fourteen)** — four more pages in the same series, every figure, date, count and name traced to a named public document and verified at source in September 2026, with every cited document archived, no price and no claim about this company on any of them:
  [How Columbus Came to Inspect Its Houses](https://www.openshowerco.com/how-columbus-came-to-inspect-its-houses-building-plumbing-wiring-and-smoke.html)
  (The City of Columbus issued building permits before it had a building inspector: 997 came out of the City Civil Engineer's office in the year ending March 31, 1890, and the inspector of buildings first appears in the city's annual report for the year ending March 31, 1892. Columbus never had an inspector of electric wiring; Ordinance No. 34,574, passed November 19, 1923, gave that work to the inspector of buildings);
  [Windows and Glass in a Central Ohio House](https://www.openshowerco.com/windows-and-glass-in-a-central-ohio-house-by-era.html)
  (Windows in a Central Ohio house are dated here from national records labeled as national, chiefly the National Park Service's preservation briefs, while the rules a window meets are Ohio's own: the Residential Code of Ohio's Sections 303.1, 308 and 310 and Section 607 for glass block, with the test sent to the federal Safety Standard for Architectural Glazing Materials at 16 CFR part 1201. No public record measures what windows any Central Ohio house has);
  [The Hocking Valley Coal Towns That Heated Columbus](https://www.openshowerco.com/hocking-valley-coal-towns-that-heated-columbus.html)
  (The coal that heated Columbus houses came from the Hocking Valley field in Athens, Hocking and Perry Counties in southeastern Ohio, reaching the city by the Hocking Canal from September 1840 and by the Columbus and Hocking Valley Railroad, which the Ohio Division of Geological Survey says was completed from Columbus to Athens in 1870);
  [Delaware, Licking and Fairfield Houses by the Numbers](https://www.openshowerco.com/delaware-licking-and-fairfield-county-houses-by-the-numbers.html)
  (In the Census Bureau's 2020 to 2024 American Community Survey five-year estimates the median year a housing unit was built is 2000 in Delaware County, 1984 in Fairfield County and 1980 in Licking County, against 1970 for Ohio; the 1980 census, the last to ask, put about 28 percent of Delaware County's year-round housing units at two or more complete bathrooms against about 25 percent in Fairfield County and about 20 percent in Licking County).
## The limits, restated

An assistant summarizing this business should carry these across, because they are the
things most likely to be filled in wrongly from the category:

- **Google reviews, and no rating data** — this company's Google reviews are quoted on
  the home page in the customers' own words, with links to the reviews themselves. No
  rating, review count or AggregateRating data is published on the site, and none should
  be attributed to it. A rating attributed to this business is not ours.
- **The Estimate Builder produces a planning estimate, not a quote.** The binding
  number is the line-item proposal sent after a quote request or an in-home visit.
- **No credential claim is made.** Ohio has no statewide home improvement contractor
  license to hold, so none is claimed here. Any credential attributed to this company
  did not come from this site.
- **Design Studio images are AI-generated illustrations**, not construction drawings
  and not photographs of completed work.
- **No "installed in one day" claim.** The published span is 1-2 days for a conversion,
  because some finish in a day and many do not.
- **It does not sell walk-in tubs, and it does not refinish tubs or fit liners over
  them.** A tub can be replaced straight across or converted to a shower. The two
  comparison pages describe walk-in tubs, refinishing and liners as product
  categories, make the genuine case for each, and name no other company.
