Walk-in tub cost dataset
This is the complete dataset behind the walk-in tub calculator, at national wage rates. It publishes two things a price list cannot: how much of the installed cost is not the tub, and how many minutes you spend sitting inside one waiting for it to fill and drain — because the door cannot open with water behind it. Last reviewed 2026-08-24.
The minutes each model costs you
| Model | Holds | Fills | Drains, gravity | Drains, pumped | Cost |
|---|---|---|---|---|---|
| Soaker | 50 gal | 12.5 min | 8.3 min | 3.1 min | $6,216 |
| Air bath | 55 gal | 13.8 min | 9.2 min | 3.4 min | $7,266 |
| Hydrotherapy | 60 gal | 15 min | 10 min | 3.8 min | $8,116 |
| Combination | 65 gal | 16.3 min | 10.8 min | 4.1 min | $10,016 |
Nobody selling one of these publishes this table, and it is arithmetic rather than opinion: gallons divided by 4 gallons a minute from an ordinary tub filler, and out at 6 under gravity or 16 with a pump. All three rates are declared model values. The user is inside the tub for the whole of it — dry and cooling while it fills, wet and cooling while it drains — because the door seals against the water. ⚠️ That is why the pumped drain is the least glamorous and most important line in this dataset: on the reference model it buys back 5.2 minutes of sitting wet, every bath, and being cold and bored is the commonest reason one of these stops being used.
How much of it is not the tub
| The tub, which is what gets advertised | $3,050 |
|---|---|
| Powered fast-drain pump | $480 |
| Plumbing — labour | $432 |
| Outward-opening door, latch and clearance trim | $400 |
| Waste, overflow, supplies and the filler | $370 |
| Surround and making good — labour | $352 |
| Wall panels, trim and making good | $340 |
| Remove the old tub and set the new one — labour | $274 |
| Take out the old tub and dispose of it | $203 |
| Grab bars, with blocking behind the wall | $163 |
| Handheld shower on a slide bar | $153 |
| Installed | $6,216 |
51% of the installed price is not the tub: the old one coming out, the waste and overflow moving because the new one sits differently, the surround rebuilt taller, an access hatch so a pump can be reached without breaking the wall open, and on anything with a motor an electrician. ⚠️ And the water heater, which is the line nobody raises. Filling to bathing temperature is a mixture, not a tank of hot: at 102°F from a heater at 120°F and a cold supply near 55°F the hot fraction is 0.72, so this tub needs about 36 hot gallons against roughly 35 usable from a standard 50-gallon tank. Those three temperatures are declared because the whole conclusion rests on them — an earlier version of this model compared the full tub volume against the tank and made every model look impossible, which was our error rather than the product’s.
Four ways out of the same problem
| An ordinary new bathtubNo — same 15-inch step over the side | $3,302 |
|---|---|
| Low-threshold shower conversion, with a seatStep over about 2 inches, and you can sit | $3,630 |
| Walk-in tub, this specificationStep over about 4 inches, and you keep a bath | $6,216 |
| Curbless tiled showerNothing to step over — a wheelchair can roll in | $7,937 |
| Soaker — no jets | $6,216 |
|---|---|
| Air bath — air jets | $7,266 |
| Hydrotherapy — water jets | $8,116 |
| Combination — air and water jets | $10,016 |
| Inward-opening door | $5,816 |
| Outward-opening door | $6,216 |
All four come from models on this site at the same wage data, on the same bathroom. ⚠️ Notice what sits at the top of the left-hand table: an ordinary new bathtub at $3,302. If the reason for all of this is that getting over the side of a bath has become dangerous, that row deserves reading before any brochure. What a walk-in tub buys over it is a bath — sitting in hot water up to the shoulders, which a shower cannot do. ⚠️ And on the right, the door: inward is $400 cheaper and it cannot be opened until the tub has drained, so a walking frame will not pass it and somebody who has fallen inside cannot be reached. For a mobility purchase that is not a saving.
On Medicare
⚠️ This dataset prices work and does not advise on benefits. Medicare, Durable medical equipment (DME) coverage (read 2026-08-24) defines durable medical equipment as equipment that is durable, used for a medical reason, typically only useful to somebody who is sick or injured, used at home and expected to last at least three years — and the equipment it lists is canes, commode chairs, hospital beds, walkers and wheelchairs. A bathtub is a fixture of the building and it is useful to anybody. Medicare Advantage plans, state Medicaid waivers and veterans’ programmes differ, so that is a question for them, and a salesperson who answers it for you is answering a question they cannot know.
Line items
83% of the reference total comes from estimated rather than official figures — the tub itself is a manufactured product with no federal price series, and it is most of the money. The reference job is a 60-inch plain soaker with an outward-opening door, a fast-drain pump, two grab bars and a handheld, replacing an ordinary tub on the ground floor: 19 trade hours, 50 gallons, 15.6 minutes inside per bath. Models and doors that are not selected sit at zero quantity, so the table below is the whole catalogue rather than one job.

The reasoning behind each figure
- Walk-in tub — Soaker — no jetsestimated, ±38%
- The plain version: a deep seat, a door and nothing else moving. It is the cheapest, the least to go wrong, the quietest, and for a lot of people it is all they actually wanted. ⚠️ It is also the one that needs no electrical work at all beyond a light, which quietly removes a whole trade from the job.
- Holds about 50 gallons at a standard 60-inch length, which is roughly double an ordinary alcove tub. That number drives two things nobody quotes: how long you sit in it waiting, and whether your water heater can fill it hot.
- ⚠️ This is the line that an advertised price is quoting, and it is well under half of what the job costs. The rest is below.
- Walk-in tub — Air bath — air jetsestimated, ±37%
- Warm air blown through ports in the shell. It feels like effervescence rather than pressure, it is gentler than water jets on thin skin, and the system dries itself out after a cycle — which matters, because a system that holds water holds what is in the water.
- Holds about 55 gallons at a standard 60-inch length, which is roughly double an ordinary alcove tub. That number drives two things nobody quotes: how long you sit in it waiting, and whether your water heater can fill it hot.
- ⚠️ This is the line that an advertised price is quoting, and it is well under half of what the job costs. The rest is below.
- Walk-in tub — Hydrotherapy — water jetsestimated, ±37%
- Pumped water through directional jets. It is the strongest massage of the three and the one most people picture. ⚠️ Water jets recirculate through pipework that stays wet between baths, so they need running through with a cleaner regularly, and that is a maintenance job somebody has to actually do.
- Holds about 60 gallons at a standard 60-inch length, which is roughly double an ordinary alcove tub. That number drives two things nobody quotes: how long you sit in it waiting, and whether your water heater can fill it hot.
- ⚠️ This is the line that an advertised price is quoting, and it is well under half of what the job costs. The rest is below.
- Walk-in tub — Combination — air and water jetsestimated, ±39%
- Both systems in one shell, usually with a heater to stop the water going cold during a long soak. It is the top of the range, it needs the most electrical work, and it holds the most water — which feeds straight into how long you sit there waiting, and into whether your water heater can fill it hot.
- Holds about 65 gallons at a standard 60-inch length, which is roughly double an ordinary alcove tub. That number drives two things nobody quotes: how long you sit in it waiting, and whether your water heater can fill it hot.
- ⚠️ This is the line that an advertised price is quoting, and it is well under half of what the job costs. The rest is below.
- Outward-opening door, latch and clearance trimestimated, ±55%
- ⚠️ The one to choose if the reason for buying this is mobility. It is the only door a walking frame can get through, and the only one that lets somebody help from outside or a paramedic open the tub without waiting for it to empty. It relies on a latch rather than on water pressure to stay sealed, and it needs clear floor space in front of it.
- Priced as a premium over the inward-opening door that most models come with as standard, because it is a different shell and a different latch rather than a hinge swapped round.
- Take out the old tub and dispose of itestimated, ±53%
- Disposal, sheeting to protect the route out and the consumables. Hours are the next line.
- ⚠️ And the one that catches people out in the other direction: a walk-in tub is taller and heavier than what comes out, and getting it IN can mean taking off a door casing or, in a tight bathroom, a section of wall. Worth measuring the route before ordering rather than after.
- Remove the old tub and set the new one — labour
- Six hours for an ordinary tub coming out and the new one going in, and ten when the old one is cast iron and has to be broken up or carried by four people.
- Waste, overflow, supplies and the fillerestimated, ±51%
- A walk-in tub sits differently from what it replaces, so the waste and overflow rarely land where the old ones did, and the filler is usually a deck-mounted set rather than a wall spout.
- This is a plumbing job whichever model is chosen. It is one of the reasons an advertised tub price and an installed price are so far apart.
- Plumbing — labour
- Seven hours: setting the tub level, connecting waste and overflow, running supplies to the filler and testing the door seal before anything is closed up.
- ⚠️ Testing the door seal with a full tub before the panels go on is the step to ask about. A door that weeps is a floor that rots, and finding out afterwards means taking the tub out again.
- Powered fast-drain pumpestimated, ±50%
- ⚠️ On paper an upgrade, in practice the difference between a tub that gets used and one that does not. The door cannot open until the water is gone, so draining time is time spent sitting wet in an empty tub with the air on your skin.
- A gravity drain moves around 6 gallons a minute and a pumped one around 16, so on a 50-gallon tub it is the difference between roughly eight minutes and three. This page calculates both, because it is the number that decides whether somebody keeps using what they bought.
- Dedicated GFCI circuit for the blower, pump or heaterestimated, ±56%
- Anything with a motor or an in-line heater wants its own protected circuit rather than sharing the bathroom receptacle, and a jetted tub often wants two.
- ⚠️ This is where the quote for a jetted model quietly becomes bigger than the quote for a soaker: the tub is dearer AND it brings an electrician into the job. A plain soaker needs neither.
- Run the circuit — labour
- Five hours to run a protected circuit from the panel to the tub and terminate it, on the assumption there is a spare way in the panel. ⚠️ If there is not, that is our electrical panel page and a different order of money.
- Larger water heater, so it can be filled hotestimated, ±43%
- ⚠️ The line nobody selling a walk-in tub brings up, and the one that decides whether the therapeutic bath is warm. A walk-in tub holds roughly twice what an ordinary tub holds, and only part of a storage heater comes out at bathing temperature.
- A typical 50-gallon heater yields around 35 usable gallons, which does not fill a 50-gallon tub hot. The options are a bigger tank, a tankless heater or accepting a tepid bath, and this page calculates which one you are in before you buy.
- Priced as the tank and the fittings. Our water heater pages price the choice properly, and this line exists so it is not a surprise.
- Swap the water heater — labour
- Five hours to drain and remove the old tank, set the new one, reconnect and test. It is a separate job in a separate room that happens on the same day.
- Grab bars, with blocking behind the wallestimated, ±53%
- ⚠️ Cheap, and for most people buying this the actual point. Getting into and out of the tub is the moment the fall happens, and falls are the leading cause of injury among older adults.
- ⚠️ A grab bar is only as good as what it is screwed into, and the wall is open now. A bar fixed to plasterboard alone will come off the wall with somebody holding it.
- Handheld shower on a slide barestimated, ±57%
- Essential rather than optional on a walk-in tub, because you are sitting down: it is the only way to rinse, and the only way a carer can help without climbing in.
- Federally regulated flow rates mean a labelled head uses less water for the same feel — which on a tub this size is worth having.
- Wall panels, trim and making goodestimated, ±53%
- A walk-in tub is taller than what comes out, so the surround never lands where the old one did and the wall above has to be finished to meet it.
- Priced with a panelled surround rather than tile, which is what almost every one of these installations uses: fewer joints, and it goes in on the same day.
- Surround and making good — labour
- Six hours to frame the shell in, panel around it, fit the access hatch the pump needs, and finish the wall above.
- ⚠️ The access hatch matters and gets forgotten: a pump or a blower that cannot be reached without breaking the wall open is a repair bill waiting to happen.
Not included in this dataset
- What Medicare will pay
- ⚠️ The commonest question about this product and the honest answer is a criterion, not a number. Medicare defines durable medical equipment as equipment that is durable, used for a medical reason, typically only useful to somebody who is sick or injured, used at home and expected to last at least three years — and what it lists is canes, commode chairs, hospital beds, walkers and wheelchairs. A bathtub is a fixture of the building and it is useful to anybody. This page prices work and does not advise on benefits: Medicare Advantage plans and state Medicaid waivers vary, and some veterans’ programmes are different again, so ask them rather than us.
- Getting it into the bathroom
- Priced as a normal delivery. ⚠️ If the route in needs a door casing removed or a stud wall opened, that is real money and it is knowable in advance: measure the narrowest point of the route before ordering. A walk-in tub does not tip on its side to get round a corner, because the door is on the side.
- A slow leak at the door seal
- Not a cost today and the failure mode that matters. The door seal is a wearing part and it is the one thing on this tub that will need attention. Ask what the seal costs, whether it can be replaced without removing the tub, and how long the warranty on it is — separately from the warranty on the shell.
- Time spent waiting
- ⚠️ The real cost of this product and it is not money. You get in, close the door, and wait for it to fill; you finish, and wait for it to drain before you can get out. This page calculates both times because nobody selling one will, and because it is the reason some of these tubs stop being used.
- Whether it is the right answer at all
- For somebody who can step over two inches, a low-threshold shower conversion is cheaper, quicker, needs no electrical work and involves no waiting. For somebody who wants to soak, or who cannot stand for a shower, a walk-in tub is the thing. We price both and put them side by side rather than selling either.
