Central Ohio houses and bathrooms, era by era

The Central Ohio bathroom, era by era: fixtures, finishes and what people choose now

A Central Ohio bathroom is largely a record of the decade its house went up, because its fixtures and finishes came from what the national market was selling then. Nobody publishes a count of what tub, tile or color is in Central Ohio bathrooms by era, so the history here is national and every date carries the publisher who gives it. The one measured local series is the Franklin County Auditor's record of how many bathrooms a house of each decade has, and it counts rooms rather than fixtures. This page walks the bathroom from the 1880s to now, gives what the surveys find people choosing today, and says where no source exists.

What this page can say, and what nobody counts

Every era statement below is national and names the publisher who dates it, because nobody counts what tub, tile or color is in Central Ohio bathrooms by decade. Two measured local records exist, both counting rooms not fixtures: the county auditor's parcel record, tabulated below, and the 1980 Census counts on the bathrooms per house page. When plumbing reached Ohio houses is on the Ohio bathroom page. The house is on the house styles page, the wall behind the tile on the how they were built page, and the makers on the who shaped them page.

The first bathrooms and the sanitary white one, 1880s to 1910s

Period Homes, a trade publication for the traditional building trades, writes that running water and soil plumbing entered houses in the 1880s and primed the evolution of a new kind of room, and that manufacturers did not get porcelain enamel to stick to metal until the late 1880s. Both statements are national. Kohler's own company history, the firm's account of itself, dates its founding to 1873 and its first plumbing product to 1883, an enameled cast iron trough sold as a bathtub. Traditional Building records a shower in an 1898 plumbing catalog, a very early entry into the modern bathroom; Period Homes says showers were uncommon in houses before the 1920s.

By 1900, Period Homes says, germ theory had made glazed all-white tile work the essential weapon against dirt and invisible microbes. The National Park Service, in its brief on historic ceramic tile floors, divides the two tiles: larger rectangular white glazed tiles for bathroom walls or wainscot, small white unglazed tiles on the floor. Period Homes gives the wall size everyone repeats, three-by-six-inch glazed white tile in running bond, later called subway tile, though the same article quotes a 1912 writer specifying four-by-six. The Park Service says colored tiles were popular too, especially for bathrooms, without a date; Period Homes puts the turn from white to color at the end of the First World War.

The tile was an Ohio industry, though not a Central Ohio one. In the last quarter of the nineteenth century, the Park Service writes, Zanesville, Ohio was the largest center for pottery and tile making in the world; it names the Mosaic Tile Company and the American Encaustic Tiling Company, established in 1876, and calls American Encaustic the largest tile company in the world in the early 1930s, closing about 1935. Zanesville is in Muskingum County, east of Columbus, and no source follows a tile from there into a Central Ohio bathroom. How long each Zanesville company lasted, where the sources disagree, is on the page about what Ohio made for houses.

The built-in tub and the compact bathroom, 1910s to 1930s

The Smithsonian's National Museum of American History gives the only institutional account found of why the tub changed shape: by the early twentieth century, it records, advice manuals and sanitary specialists preached against heavy free-standing tubs, and manufacturers began to market built-in ones. Period Homes says the same in trade language, and Kohler's 1922 catalog argues for the built-in bath on hygiene grounds. The museum's tubs are solid porcelain and Kohler's enameled cast iron: the argument is shared, the product is not.

The date is the company's own. Kohler's history dates what it calls the industry's first one-piece, built-in bath with an integral apron to 1911, and Period Homes gives the same year; no government or institutional record dates it at all. Kohler's 1917 catalog shows that tub in recess, wall and corner patterns. Period Homes says it was commonly five feet long, and that spanning it across a five-foot-square room created the compact bathroom of wall-hung lavatory, toilet and tub-shower. Commonly is right and standard is not: the 1922 catalog lists four lengths over the rim, 54, 60, 66 and 72 inches, and captions its model bathrooms six by eight, seven by eight and eight by twelve feet. Those are a maker's model rooms, not a measurement of any house, and no source gives a dimension for the postwar hall bathroom.

Color, then the postwar three-fixture bathroom

Two dates belong to the colored fixture and they are not the same fact. Kohler's own company history dates cast iron and vitreous china plumbing products in matching pastel colors to 1927; Traditional Building says 1928 and names the catalog that announced them, which the Building Technology Heritage Library also dates 1928. One is the year the company says it offered the colors, the other the year of the catalog. Traditional Building lists that first generation as including horizon blue, old ivory, spring green, lavender and autumn brown, with a sixth color. Period Homes says nickel plating was the normal fitting finish after 1900, and chrome surpassed it in the mid-1920s.

After the war the bathroom got plainer. Traditional Building, writing about a 1946 plumbing catalog, says the three-fixture bathroom of toilet, sink and bathtub was all that was needed for low-cost houses and was common in the millions built immediately after the Second World War; by the 1950s, it adds, the pink bathroom was available from most plumbing fixture companies. The federal housing department's 1999 rehabilitation guide separates the two tub materials: enameled cast iron is heavy, durable and quiet and will last indefinitely, while enameled steel is not as strong and chips more easily.

The Lustron bathroom, manufactured in Columbus

The one bathroom of the period federal records describe in detail was made in Columbus. By the Ohio History Connection's account, between 1947 and 1950 the Lustron Corporation built more than 2,000 porcelain steel homes in its Columbus factory; the counts and the plant's dates differ between sources, and the house styles page sets them side by side. Three nominations document the bathroom, in houses standing in Georgia and Tennessee though manufactured in Columbus: walls of two-foot-square porcelain-enameled steel panels, tan and light gray in one house, a steel pocket door sliding on an overhead track with no protruding hardware, and an original stamped steel bathtub set in, a little over five feet long.

Plastic, the vanity, and the decades nobody wrote down

Fine Homebuilding dates the next change nationally to the 1960s: until then, it writes, a knee-buckling delivery of a heavy tub upstairs was routine, and a boom in plastics ended it. That magazine and the federal guide agree that a plastic tub-shower is fiberglass-reinforced plastic with a polyester gel-coat surface, or molded acrylic.

Fine Homebuilding states the constraint that decides how one comes out: one-piece units are limited by their size to new construction, while a remodel unit comes in three or four pieces small enough to fit through a finished house. United States Patent 3,827,086, granted in 1974 to the Owens-Corning Fiberglas Corporation, says the same in a federal document.

Traditional Building, writing about a vanity catalog of about 1960, says the bathroom sink set in a cabinet was a mid-twentieth-century development and laminate countertops another innovation of that era. The federal guide describes a cast polymer or cultured stone top as chips of natural stone in a polyester resin whose gel coat commonly cracks around the drain. Sheet vinyl and old paint belong to the lead paint and asbestos page.

Then the published record stops. No publisher found describes or dates the primary bathroom plan of the 1980s to the 2000s, the corner or garden tub beside a separate shower; the 1999 federal guide on kitchens and baths contains no instance of garden tub, corner tub, platform tub, deck-mounted or sunken. The decade-by-decade description of Columbus bathrooms on the common shower systems page is an inference from the year the houses were built, and this page does not repeat it.

What the Franklin County Auditor's record counts, decade by decade

The series here is the Franklin County Auditor's own appraisal extract, downloaded on September 6, 2026 from the auditor's bulk download of the August 15, 2026 snapshot. The rows are single-family parcels: property class R with a land use code of 510 through 515, which in the auditor's table means a one-family dwelling on a platted or unplatted lot, joined to the primary dwelling record with a year built. Of 494,522 parcel records, 297,465 qualified.

The auditor's documentation labels the two fields FIXTURES BATH (FULL BATHS) and FIXTURES HALF (HALF BATHS), tabulated here against YEAR BUILT, and those labels are its whole published definition: the auditor states nowhere what physically counts as a full or half bathroom, and marks nowhere whether a year built is actual or estimated. The count is what an assessor recorded for tax purposes as of whenever the parcel was last reviewed, so it can lag a remodel either way, and it counts parcels by recorded year built, not houses built. It counts rooms and never fixtures, so nothing here describes a tub, a tile or a color.

2020s8,9182.241.64

Read the shape, not one row. The mean is lowest in the 1940s and rises in almost every decade after; the share with exactly one full bathroom does not drop below half until the 1960s and is near zero by the 2010s. Every row describes the houses as the assessor last recorded them, not as they were built, and the record does not say why the oldest row is not the lowest. The last row runs 2020 to 2025 only.

The Census figures are on the bathrooms per house page and are not repeated, because the two are not one series: the 1980 Census counted complete bathrooms in housing units as the household reported them, and the auditor records what the assessor recorded for tax purposes.

What people choose now

Four surveys measure the present, each asking a different group a different question. In the National Association of Home Builders survey published as What Home Buyers Really Want, 2024 edition, a national survey of more than 3,000 recent and prospective home buyers, 14 of 18 bathroom features were rated essential or desirable by half or more of buyers; the three highest were both a shower and a tub in the primary bathroom at 78 percent, a linen closet at 76 and a private toilet compartment at 70. That report is sold and was not opened.

In the National Kitchen and Bath Association's 2026 Bath Trends Report, 55 percent of the industry professionals surveyed said a larger shower size is more important than having a bathtub. That is not a consumer survey: 688 respondents from the association's own community, 61 percent of them designers, each required to have designed, specified or sold products for a bath project in the past year. The report is free to members only and was not opened.

Houzz surveyed 1,737 homeowners on its own site about a recent or planned bathroom renovation, published September 23, 2025; its users are not a random sample. In that survey 34 percent upgraded a bathtub, 26 percent removed one and 9 percent kept the one they had, and among those who removed it 82 percent enlarged the shower. Low-curb showers were the most common choice at 44 percent, alcove 42 and curbless 20, with multiple selections possible; the curbless shower page covers that step. Freestanding flat-bottom tubs led at 45 percent, alcove tubs 40 and corner tubs 2. Wet rooms were one in six renovated bathrooms, and the wet room page owns that subject. A century after the sanitary white bathroom, white was the most common shower wall color at 36 percent and the most common countertop color, in 48 percent of renovated bathrooms.

Aging in place, in the surveys' numbers

These are survey figures and nothing more. In AARP's 2024 Home and Community Preferences survey of 3,090 adults age 18 and older, 75 percent of the respondents age 50 and older said they would like to live in their current home for as long as possible, and 72 percent of those planning home modifications said they were looking to upgrade the bathroom. The Harvard Joint Center for Housing Studies reports that 3.7 percent of owners took on at least one project to make their home more accessible in 2022 and 2023, up from 2.8 percent in 2018 and 2019; the question, asked of owners who had improvement projects, was: Did you do any home improvements to make your home more accessible for people with physical limitations, such as people using a wheelchair or a walker? Citing the National Association of Home Builders, it says 93 percent of remodelers doing accessibility work in 2023 installed grab bars, 83 percent curbless showers and 77 percent higher toilets.

Houzz found 68 percent of renovating homeowners considering special needs, and in the kitchen and bath association's survey of industry professionals 32 percent called aging-in-place design a mainstream trend now, with 48 percent saying it is on its way. None of it is new: the federal guide already recorded in 1999 that where space is tight the tub, if it is not the only one in the home, is often exchanged for an oversized shower with a seat and grab bars, which the grab bars page covers.

When an old bathroom changes

The National Park Service treats bathrooms as secondary spaces in a historic building, which it says may accept greater change without compromising the building's historic character; that is federal rehabilitation guidance, not a local rule, and a Columbus historic district commission sets its own. The same agency says attaching new fixtures may be one of the most common sources of damage to a historic tile floor, because a fixture of a different size exposes areas never tiled.

What happens when a tub of any of these eras comes out, and what the drain, the valve and the wall behind it ask for, is on the tub-to-shower conversion page; the categories of shower sold in Columbus today are on the common shower systems page. Whether any of that moves a house's worth has its own resale page, and nothing here speaks to it.

The short version. Kohler's own history dates its first bathtub to 1883 and the one-piece built-in tub to 1911; Period Homes says that tub was commonly five feet long, which is where the five-foot alcove comes from, and the same maker stocked four lengths, so five feet was common and never standard. White tile answered germ theory by 1900, colored fixtures arrived in the late 1920s and the plastic tub in the 1960s, and no publisher describes the corner tub plan of the 1990s. In the auditor's record the county's 1950s houses average 1.36 full bathrooms and its 1990s houses 2.04.

Common questions

When did colored bathroom fixtures arrive, and is there a Columbus date for it?

No publisher found dates colored fixtures in Columbus or anywhere in Ohio, so the only available dates are national and each belongs to its publisher. Kohler's own company history dates cast iron and vitreous china plumbing products in matching pastel colors to 1927. Traditional Building gives 1928 and names the catalog that announced them, and the Building Technology Heritage Library dates that catalog 1928 as well. Those are two different facts rather than a disagreement: one is the year the company says it offered the colors, the other the year of the catalog. Traditional Building says other manufacturers quickly followed.

What was in a 1950s Columbus bathroom?

Nobody counts fixtures or finishes in Columbus bathrooms by decade, so the honest answer is a national description beside a local count. Traditional Building says the simple three-fixture bathroom of toilet, sink and bathtub was common in the millions of houses built immediately after the Second World War, and that by the 1950s the pink bathroom was available from most plumbing fixture companies. The federal rehabilitation guide separates the two tubs of the period: enameled cast iron, which it calls heavy, durable and quiet, and enameled steel, which it says is not as strong and chips more easily.

How many full bathrooms does a Franklin County house built in the 1950s have?

In the Franklin County Auditor's parcel record as downloaded on September 6, 2026, the 47,888 single-family houses in the county with a 1950s year built carried a mean of 1.36 full bathrooms and 0.26 half bathrooms, and 68.44 percent of them had exactly one full bathroom. That is the auditor's own count of what an assessor recorded for tax purposes, as of whenever the parcel was last reviewed, so it can lag a remodel in either direction. It counts rooms and never fixtures or finishes, and it describes one county's assessment record on one day rather than Ohio or Central Ohio.

Why do so many older Central Ohio bathrooms have a five-foot bathtub?

The trade publication Period Homes traces it to a design convention rather than to anything local: the built-in tub was commonly made as a five-foot unit, and spanning it across a five-foot-square room produced the compact bathroom of wall-hung lavatory, toilet and tub with a shower over it. Five feet was common and not standard. Kohler's own catalog of 1922 stocks the built-in bath in four lengths over the rim, 54, 60, 66 and 72 inches, with the 60-inch tub in its illustrated model bathrooms. Two National Register nominations measure a little over five feet in Lustron houses manufactured in Columbus.

Was the tile in an old Ohio bathroom made in Ohio?

Nothing found answers that for any particular house. The National Park Service writes that in the last quarter of the nineteenth century Zanesville, Ohio was the largest center for pottery and tile making in the world, and names the Mosaic Tile Company and the American Encaustic Tiling Company, established in 1876, among its factories; it says American Encaustic was the largest tile company in the world in the early 1930s and closed about 1935. Zanesville is in Muskingum County, about fifty miles east of Columbus, and no source found follows a tile from there into a Central Ohio bathroom.

What was the bathroom like in a Lustron house made in Columbus?

National Register nominations describe it closely. The walls are lined in two-foot-square porcelain-enameled steel panels, tan and light gray in one documented house. The bathroom has a porcelain-enameled steel pocket door that slides and rolls on an overhead track with no protruding hardware, and the original bathtub is stamped steel, set in and measuring a little over five feet. By the Ohio History Connection's account, between 1947 and 1950 the Lustron Corporation built more than 2,000 porcelain steel homes in its Columbus factory; one nomination gives 2,500. The documented houses themselves stand in Georgia and Tennessee.

Is the corner tub and separate shower plan of the 1990s documented anywhere?

Not in any source this page could find. No publisher describes or dates that primary bathroom plan, the corner or garden tub beside a separate shower. The federal rehabilitation guide of 1999 on kitchens and baths, which is where it should sit, contains no instance of garden tub, corner tub, platform tub, deck-mounted or sunken. What is measured is the present: in Houzz's 2025 survey of 1,737 homeowners on its own site, corner tubs were 2 percent of the tubs chosen and deck-mounted tubs 6 percent. That measures what goes in now, not what was built then.

What do recent surveys say people did with the bathtub when they renovated a bathroom?

In Houzz's 2025 survey of 1,737 homeowners on its own site, which is not a random sample, 34 percent upgraded a bathtub, 26 percent removed one, 9 percent kept the one they had and 25 percent never had one. Among those who removed it, 82 percent used the space to enlarge the shower. A different question gets a different answer: in the National Association of Home Builders survey published as What Home Buyers Really Want, 2024 edition, having both a shower and a tub in the primary bathroom was the highest-rated bathroom feature, at 78 percent.
