Walk-in tub services

Walk-in tub companies typically offer four services: a tub-for-tub replacement in the existing alcove, a shower-to-tub or tub-to-shower conversion, a wheelchair-accessible install with a wide outward-swinging door, and repair or seal service on an existing unit. A straightforward swap into an existing alcove is the cheapest path; anything that moves plumbing, changes the footprint, or requires electrical work costs substantially more.

Most installs replace an existing 60-inch alcove tub. That is the best case: the drain and supply are already where they need to be. This Old House's 2026 breakdown puts a typical 60-by-32-inch walk-in tub installation at about $4,632 total, with roughly $1,205 of that labor and $3,427 materials.

Converting a shower into a walk-in tub is a bigger job — This Old House puts it at roughly $3,000 to $8,000 for the conversion work — because the drain location, waterproofing and often the framing change.

Two utility upgrades come up constantly and are frequently left out of the first quote. Walk-in tubs hold more water than standard tubs, and many installations need a larger water heater. Hydrotherapy jets, heated seats and powered drains need dedicated electrical circuits. Ask about both in writing.

This vertical has a documented high-pressure sales pattern: long in-home demos, prices that change during the visit, and "today only" discounts. Nothing about a bathroom renovation is time-sensitive. Get three quotes and let the price sit overnight.

How to choose

Start with the alcove measurement
Measure the existing tub opening length, depth and width, and note where the drain is. That single set of numbers determines whether you are in the cheap scenario or the expensive one.
Ask what the quote excludes
Water heater upgrade, electrical circuit, tile and wall repair, door threshold modification, and permit fees are the usual omissions.
Confirm who does the plumbing and electrical
Ask whether licensed plumbing and electrical trades are used and whether their work is permitted. Requirements vary by jurisdiction — confirm with your local building department.
Ask about the door swing
Inward-opening doors save space but reduce entry width and cannot be opened when the tub is full. Outward-opening doors need clear floor space. Measure your bathroom before choosing.
Get repairs quoted separately
If you already have a walk-in tub and the door leaks, that is usually a gasket or alignment service call, not a reason to buy a new tub.

FAQ

Walk-In Tubs services — common questions

Still have a question? Talk to our team →

A straight swap into an existing alcove is typically a short job; conversions, electrical work and tile repair extend it. Ask each company for a written day count and what happens if the bathroom is your only one.
Often. Most walk-in tubs hold roughly 40 to 80 gallons when filled, versus far less for a standard tub, and guidance from installers is that 40-gallon heaters are frequently inadequate. Ask the installer to state, in writing, whether your heater is sufficient.
If the tub has jets, a heated seat, an air blower or a powered fast drain, it needs power. Ask whether a dedicated circuit is included in the quote and who pulls any required permit.
Sometimes, but door swing and floor clearance decide it. An outward-swinging door needs clear space in front; an inward-swinging door narrows the entry. Have the installer verify clearances on site before you order.
