Four routes, compared on the published figures this site is allowed to use and on what each one actually changes about using the room. Which route fits is a judgement made in the home, by the contractor who looks at it - this site does not assess homes and does not decide scope.
The four routes, and the published basis for each
| Route | Published basis | What it changes |
|---|---|---|
| Tub-to-shower conversion | $2,000 - $12,000, with most projects at $3,000 - $7,000 depending on prefab kit against custom tile | Removes the tub and the step over its wall, in the footprint you already have |
| Full accessible bathroom | Anchored on the walk-in or curbless conversion range, $10,000 - $16,000 for a walk-in and $14,000 - $22,000 for a roll-in or curbless build, higher with custom tile, a linear drain and structural floor work; additional work outside the wet area has no published range used on this page | The wet area and the room around it - doorway, toilet height, floor surface |
| Walk-in tub | No published range is used on this page; the contractor quotes it as its own job | A seated soak in the existing tub space, entered through a door in the tub side |
| Grab bars only | $200 - $350 per bar professionally installed | Support at the tub, shower and toilet, with no change to any fixture |
Three of the four rows are priced from the published 2026 guides cited at the foot of this page. The walk-in tub is not, and it would be misleading to pretend otherwise: the published ranges this site uses cover conversions, grab bars and ramps, so a walk-in tub is a figure you have to get from a contractor rather than read here.
Stepping in: the threshold is the whole question
Almost every bathroom used for a lifetime was built around a tub with a wall you step over, and that step is the part of the room people stop being able to make. A tub-to-shower conversion removes it by removing the tub: the shower floor sits where the tub floor was, and you walk in rather than climb in. A curbless or roll-in conversion removes the remaining curb as well, by rebuilding the floor to drain.
The other two routes answer a different question. A walk-in tub keeps the tub and puts a door in its side, so the user still sits down into it and steps over a sill to get in - which is why a walk-in tub is often the wrong answer for someone who can no longer step over anything, and why the price question comes second to that one. Grab bars change nothing about the tub wall: they make the existing step safer to take for someone who can still take it.
Seated use
Seated use is where a shower conversion and a walk-in tub overlap, and where the fitting list matters more than the headline price. A converted shower can be built with a bench or a folding seat and a hand-held shower on a slide bar, so the same room works standing or seated. A walk-in tub is built around a seat by definition. Grab bars only is the route for someone who still stands but does not trust the floor, with bars at the shower entry, the tub and the toilet.
None of that is a recommendation about any person's needs. The household decides what is wanted, the contractor prices the route they choose, and for questions about what a particular person can safely do, that is a conversation for their own clinician - not for this site and not for a quote.
Wheelchair access is a different specification
If a wheelchair or a walker has to enter the wet area, only the curbless end of this list qualifies. A roll-in or curbless shower needs a sloped floor pan, a drain that takes the water, and usually a floor that has been recessed or rebuilt - which is exactly what separates the walk-in and curbless published range from a simple tub swap. The doorway is the other half of it: a 28 inch bathroom door is a common local situation and a wheelchair does not fit through one, so widening the opening is part of the scope, not an extra.
The routes that do not work here are worth naming. A walk-in tub is entered through a door in the tub side by someone who steps over a sill and sits down; it addresses neither wheelchair access nor walking entry. Grab bars alone do not widen a door or remove a threshold. And a threshold ramp at an exterior door does nothing about the bathroom inside the house - a home usually needs both conversations, and they are priced separately.
What decides between them
The questions that actually decide it are the ones only your household can answer, and then the ones only a contractor in the room can:
- What happens now - stepping over a tub wall, standing for a shower, transferring to a toilet, or coming in with a wheelchair or a walker?
- Is the room expected to serve one person or two, and does it need to keep working if someone's mobility changes again?
- Can the route be built once at this stage, or would it have to be rebuilt later to get to curbless? A contractor can say what each stage costs; only you can say which is worth doing now.
- Which route are you quoting, and what did you see in the room that decided it?
- Is the price for a prefab kit or custom tile, and is the floor structure work included?
- Will the floor be recessed or rebuilt for a curbless entry, and what slope will it drain at?
- Where will the grab bars be fixed, and how is the blocking confirmed?
- Which permit is needed, does the HOA have to approve it, and who pulls the permit?
- What is the Florida contractor licence number, and what is excluded from the price?
The licence number is free to check on the DBPR record before you sign, whichever route you choose.
Frequently asked questions
Is a tub-to-shower conversion cheaper than a full accessible bathroom?
Usually, yes, because it works inside the footprint you already have: the published range for a conversion is $2,000 - $12,000 with most projects at $3,000 - $7,000, against $10,000 - $16,000 for a mid-range walk-in and $14,000 - $22,000 for a curbless build. The difference is the floor and the room around it - recessing the floor to drain, widening a doorway, the floor surface - which a conversion leaves alone.
Does a walk-in tub work for a wheelchair?
No. A walk-in tub is entered through a door in the tub side by someone who steps over a sill and sits down, so it is not a wheelchair route and the published guides used here note it addresses neither wheelchair access nor walking entry. Wheelchair access needs a curbless or roll-in shower with a sloped floor pan and a drain that takes the water. No published price for a walk-in tub is used on this site.
Can grab bars alone be enough?
For someone who can still step over the tub wall and stand but does not trust the floor, bars are the smallest change on this list at $200 - $350 per bar installed. They do not remove the step, do not widen a doorway and do not give a seated shower. The bars have to be fixed into blocking or studs, so if there is none behind the tile, the wall has to be opened first.
Why does a curbless shower cost more than a walk-in one?
Because it is a floor job as well as a bathroom job. A tub-out walk-in build is published at $10,000 - $16,000, and the roll-in or curbless version goes above that at $14,000 - $22,000: the floor is recessed or rebuilt with a slope to the drain, often with a linear drain instead of a centre one, and the structure underneath has to take it. Published guides price that extra as structure, not as finish.
Which route should we choose?
That is decided in the room, not on a page. What this site can give you is the published range for each route, what each one changes about stepping in, seated use and wheelchair access, and the list of questions to ask. The contractor you are introduced to looks at the bathroom, the doorway and the floor and writes the scope and the price; this site does not assess the home and does not decide scope.
