Walk-in tub or walk-in shower: which one?
Both exist to take the step out of bathing, and they do it in opposite ways: a walk-in tub keeps the bath and puts a door in the side of it, and a walk-in shower removes the tub altogether. We build showers and do not sell walk-in tubs, so read this knowing which side of the trade we are on. It is written anyway, because the question comes up in most conversations about an aging-in-place bathroom, and a homeowner deserves the whole answer before either salesperson arrives.

What a walk-in tub is
A deep bathtub with a watertight door in its side and a built-in seat at about chair height. You step over a low sill, sit down, close the door, and fill the tub around you. When you have finished, you drain it, and only then will the door open. Most are made to fit the five-foot alcove a standard tub leaves behind, and many are offered with a hand sprayer, air or water jets, and a heated seat. It is a bath taken sitting upright, in a fixture built for one person at a time. The glossary entry has the short version.
What a walk-in shower is
Any shower you step into rather than climb into. A curbless shower goes further and has no step at all: the shower floor and the bathroom floor sit at the same level, so a walker or a wheelchair rolls straight in. Four of our six packaged systems sit on a one-piece pan with no step, a hand-built tile floor laid level with the room does the same thing in any shape, and a wet room takes it to its conclusion by making the whole bathroom the shower.
The trade-offs the brochure leaves out
None of these is a reason not to buy a walk-in tub. They are the things a person should picture before buying one, because the photograph shows a tub full of warm water and none of them.
You sit in it while it fills, and while it drains
The door seals against the water, so it cannot open while the tub is full. You sit in the empty tub while it fills, and you sit in the emptying tub until the door will release, several minutes each way, at whatever temperature the bathroom happens to be. Fast-fill valves, fast drains and heated seats exist precisely to shorten and soften that wait, and they are worth asking about on any model.
It uses a great deal of hot water
A walk-in tub is deep, and it holds more water than a standard tub, most of which wants to be hot. Whether your water heater can fill it warm in one go is a question to ask before buying rather than after, and the honest answer sometimes involves a bigger heater.
The door is a seal, and a seal is a maintenance item
It has to be kept clean, it wears, and unlike almost anything else in a bathroom, a door seal that fails puts the water on the floor rather than down the drain.
The step is low, not gone
The sill of the door is a few inches high: far less than a fifteen-inch tub wall, and more than nothing. A person transfers over it from standing or from a chair. A wheelchair does not roll into a walk-in tub; a curbless shower is the arrangement built for that.
It is a bathtub, for better and for worse
It keeps a tub in the house, which matters if it would otherwise be the only one, because real estate agents generally advise keeping at least one bathtub in a home. It also occupies the whole alcove, cannot be shared, and is not a place two people take turns in quickly on a weekday morning. Models with jets, a pump or a heated seat need an electrical circuit of their own, which is part of the installation rather than an extra to add later.
What the shower gives up
The soak. A walk-in shower is used standing or seated under running water, and nobody lies down in it. If sitting in warm water is the point of bathing for you, no shower replaces that, and the tub is the honest answer. A curbless entry also depends on what the floor structure allows, which is straightforward over a slab and more involved on a wood-framed upper floor, and the curbless page explains why. Where a floor will not take a curbless entry, a one-piece pan with a beveled front gives a very low step with no excavation at all.
Who each one is for
| The situation | Walk-in tub | Walk-in shower |
|---|---|---|
| Uses a walker or a wheelchair | Transfers over a low sill, usually with help | Rolls or walks straight in with no step |
| Bathes rather than showers | Built for exactly this | No soak at all |
| More than one person uses the bathroom in the morning | One person, one fill, one drain | Seconds between users |
| A caregiver helps with washing | Reaching into a deep tub | A hand sprayer and a seat, helped from outside the spray |
| Cleaning is the complaint | A tub interior plus a door seal | Groutless walls and an open floor |
| The only tub in a house that may be sold | Keeps a tub in the house | Removes it, which agents generally advise against |
| Wants the bathroom back quickly | Depends on the installer | One to two days on site with us |
A walk-in tub suits someone who genuinely wants to bathe rather than shower, will use it most days, can transfer over a low sill, does not mind the wait while it fills and drains, and wants a bathtub kept in the house. A walk-in shower suits nearly everyone else who is asking the question: anyone using a walker or a wheelchair, anyone who showers rather than bathes, a household where more than one person uses the bathroom in the morning, anyone for whom cleaning is the complaint, and any situation where a caregiver helps, because a hand sprayer and a seat let that happen from outside the water.
The question underneath the question
Most people asking this are really asking how to stay in their own house, and both answers do that. The honest way to decide between them is to picture an ordinary Tuesday rather than the brochure photograph: who gets in, how, how long it takes, and who cleans it afterward. If that picture has someone sitting in a tub waiting for it to fill, and they are content in it, buy the tub. If it has someone stepping into a shower and being finished in ten minutes, build the shower.
Where we stand
We build walk-in and curbless showers, replace tubs and showers straight across, and do full remodels and custom tile, and walk-in tubs are not something we sell. If what you actually want is a bathtub that is easier to use than the one you have, a straight tub replacement is work we do. And if the tub being considered is the only one in the house, we raise the resale question before a contract rather than after, whichever way you are leaning. The resale page has that conversation in full, and the aging-in-place page covers the shower version of this bathroom in detail.
Common questions
What is a walk-in tub?
A deep bathtub with a watertight door in its side and a built-in seat at about chair height. You step over a low sill, sit down, close the door, and fill the tub around you; when you are finished you drain it before the door will open. Most are sized to fit the five-foot alcove a standard tub leaves behind, and many offer a hand sprayer, jets and a heated seat. It is a bath taken sitting upright, built for one person at a time.
Is a walk-in tub or a walk-in shower better for aging in place?
For most households a walk-in shower, and the reasons are practical rather than a matter of taste. A shower with no step is usable by a walker or a wheelchair, takes seconds rather than a fill-and-drain cycle, can be shared by everyone in the house, and is far easier to keep clean. A walk-in tub is the better answer for somebody who genuinely wants to bathe rather than shower, will use it most days, can transfer over a low sill, and does not mind waiting in the tub while it fills and drains. We build showers and do not sell walk-in tubs, so weigh our answer accordingly.
Can a wheelchair user use a walk-in tub?
Not by rolling in. The door of a walk-in tub has a sill a few inches high and the seat is inside the tub, so a wheelchair user transfers from the chair, over the sill, onto the seat, usually with help. A curbless shower is the arrangement built for wheeled access: the floor runs level into the shower, and a roll-in or transfer approach is possible without lifting anything.
Why do you have to wait inside a walk-in tub?
Because the door seals against the water, so it cannot be opened while the tub is full. You sit in the empty tub while it fills and sit in the emptying tub until the door will release, several minutes each way, at whatever temperature the bathroom is. Fast-fill valves, fast drains and heated seats exist to shorten and soften that wait, and they are worth asking about on any model, along with whether your water heater can fill the tub warm in one go.
Does a walk-in tub count as a bathtub for resale?
Yes. It is a bathtub with a door in it, so a house with a walk-in tub still has a tub, which matters if it would otherwise be the only one. It is also a specialized fixture that a buyer may or may not want, so it is not the same as a standard tub in a buyer's eyes. If the tub being replaced is the only one in the house, that trade-off is worth thinking through whichever way you go, and we will say so before you commit to a conversion.
Do you install walk-in tubs?
No. We build walk-in and curbless showers, replace tubs and showers straight across, and do full bathroom remodels and custom tile work, and walk-in tubs are not something we sell. This page exists because the question comes up in nearly every conversation about an accessible bathroom, and we would rather give the whole answer, including the case for the tub, than pretend the other option does not exist.
