The comparison
You have probably been shown both. They solve the same problem in very different ways, and the right answer depends almost entirely on how she will actually use it. Here is the honest case for each, including when you should pick the one we do not build.
The difference
They solve the same problem in very different ways.
A walk-in tub is a bathtub with a watertight door in the side. She opens the door, steps over a low sill, sits down, closes the door and fills the tub around her.
A walk-in shower replaces the tub entirely with a low-step or curbless enclosure, a bench, grab bars and a handheld shower.
Walk-in tub
What it is good at
A bathtub with a door in the side, so she never lifts a leg over a tub wall.
✓She can have a full bath, seated, if bathing matters to her
✓Warm water immersion can help with arthritis and circulation
✓Usually fits the existing tub footprint, so the room does not change
×She sits in it while it fills and again while it drains, several minutes each way, wet and cold
×The door seal is a long-term maintenance item and a leak is a floor problem
×A carer cannot easily reach past the door to help
×If she cannot lower herself onto the seat, it does not work at all
×Typically more expensive than most shower conversions
Walk-in shower
What it is good at
The tub comes out and the room is rebuilt around how she actually moves.
✓In, washed and out in a few minutes with nothing to wait for
✓She can sit on the bench or stand, whichever she can manage that day
✓A carer can reach in from outside with no door in the way
✓Works with a walker, and curbless works with a wheelchair
✓Keeps working as mobility declines further
×No option for a full soak
×Removing the only tub can affect resale to families with young children
Side by side
The seven differences that decide it.
| Walk-in tub | Walk-in shower | |
|---|---|---|
| Time to get washed | 15 to 25 minutes | 5 to 10 minutes |
| Waiting wet while it fills or drains | Yes, both | No |
| Carer can assist from outside | Difficult | Yes |
| Works with a wheelchair | No | Yes, curbless |
| Long-term maintenance item | Door seal | None beyond normal |
| Install time | Typically 3 to 5 days | 4 days low-step, 7 curbless |
| What we build | No | Yes |
Where we would send you elsewhere
When a walk-in tub is genuinely the better answer.
If she loves a bath, has always had one, and the thing she is grieving is the loss of soaking rather than the difficulty of washing, a shower will not give that back. That matters more than efficiency.
If there is a clinical reason for warm water immersion and her occupational therapist or physician has recommended it, build to the recommendation, not to our preference.
And if she can lower herself onto a seat comfortably and there is a second bathroom in the house with a shower in it, the trade-offs of a walk-in tub matter far less.
In those cases, say so and you will get a straight answer. You would be pointed to someone who installs walk-in tubs properly, rather than talked into the thing we happen to build.
Our honest view
For most people, the shower wins on the thing that matters.
Not because it is cheaper, and not because it is more comfortable. Because a walk-in shower keeps working as she gets less mobile, and a walk-in tub stops working the day she can no longer lower herself onto the seat.
You are almost certainly solving for the next ten years, not the next one. That is the whole argument, and it is the only one worth making.
