For most people who find bathing hard, the first purchase should be grab bars. Installed, they cost about $90 to $300 according to Fixr's price guide. A walk-in tub costs $3,000 to $10,000 for a basic soaker, per NCOA, and a curbless walk-in shower runs about $2,500 to $9,000 per Fixr. A tub or a shower only makes sense once the person has outgrown what bars, a seat and a handheld shower can do.

NCOA says its tub ranges include installation. Plumbing, electrical or water-heater work may come on top, so ask each installer to itemize it. Fixr's figures are four years old, so check every number here against two or three local quotes. Fixr also lists a walk-in tub at $3,000 to $25,000, far wider than NCOA's range, which shows how much the number depends on who is quoting.

Grab bars come first because they fix the step and the stand-up

CDC's fall-prevention advice lists grab bars inside and outside the tub or shower and next to the toilet among the basic changes (CDC, preventing falls). Put one at the edge where a person steps over the tub wall and one where they stand up from the toilet or the tub floor. Each costs a fraction of any rebuild.

A towel bar will not do the job. The ADA's standard for public buildings asks for a bar 1-1/4 to 2 inches in diameter, mounted 33 to 36 inches above the floor, with a 1-1/2 inch gap to the wall, rated for 250 pounds of force (ADA 2010 Standards, section 609). Private homes are not bound by it, but it is a reasonable spec to give an installer. The bar has to be anchored into blocking or a stud, so ask the installer how they will anchor it.

Bars do not help a person who cannot lift a leg over the tub wall or cannot stand long enough to wash. For that person the next steps are a bath seat or bath lift, or one of the two bigger options below.

A walk-in shower suits people who can stand or transfer to a seat

A curbless shower removes the step entirely. It works for someone who can stand with support, someone using a shower seat, and, with the right size and drain slope, someone in a wheelchair or using a walker. It also stays useful as needs change, because it asks nothing of the bather beyond getting in.

The cost is the rebuild. The ADA standards set shower compartment rules in section 608. Ask the installer for the dimensions and slope they plan, and check them against that section.

A walk-in tub suits people who want to soak and can manage the door

The person a walk-in tub is built for has painful joints, wants a deep, warm bath, can sit down unaided, and has a bathroom with room for it.

The design has constraints a standard tub does not. The door is in the side of the tub, so water cannot be added or drained with it open. The bather sits inside with the door shut while the tub fills and has to stay put while it drains. In a cool bathroom that is a long time to sit wet. Fill and drain times and the water heater size needed vary by model; ask for the spec sheet in writing before you sign.

A walk-in tub also still has a threshold, a seat to reach and a door to latch. For someone who cannot sit down or stand up safely, it does not solve the transfer problem. For someone with dementia or poor balance it may add a new one: being unable to get out until the water is gone.

Which option fits which person

  • Can step over the tub wall with a hand on something solid: grab bars, a non-slip mat, a shower seat and a handheld shower head.
  • Can stand but fears the step, or may need a walker or wheelchair later: a curbless shower.
  • Wants to soak, can sit and stand unaided, and has the space: a walk-in tub.
  • Cannot transfer without help: talk to an occupational therapist or doctor before spending anything. A bath lift, a roll-in shower or a caregiver-assisted routine may be better than any tub.

NCOA lists bath lifts, shower chairs and roll-in showers as alternatives to walk-in tubs, alongside handrails and grab bars.

Insurance rarely pays, and the exceptions are narrow

Original Medicare generally does not cover walk-in tubs, which NCOA says are classed as home modifications rather than durable medical equipment. Medicare.gov's page on durable medical equipment describes covered equipment as medically necessary items such as walkers, wheelchairs and commode chairs, and does not mention bathtubs or grab bars (Medicare.gov, DME coverage). Its list is not exhaustive, so ask a Medicare-enrolled supplier about a specific item.

NCOA reports that some Medicare Advantage plans offer home modification allowances of $200 to $2,000 a year, that Medicaid help varies by state and often runs through waiver programs, and that VA grants such as HISA and SAH may help eligible veterans. It also notes a possible medical-expense deduction if a doctor prescribes the tub, limited to expenses above 7.5% of adjusted gross income. Ask a tax professional before counting on it.

Spend in this order: bars, reassess, then quote any rebuild

Start with bars at the tub or shower and the toilet, a non-slip surface and a night light. Reassess in a few months with the person who bathes there. If bathing is still hard, get an occupational therapist's view on whether the problem is the step, the standing or the transfer, because the answer points to a shower, a lift or a tub. Get at least two quotes for any rebuild, and ask each for the total including plumbing, electrical and disposal of the old tub.

For medical questions about balance, dizziness or falls, talk to a doctor.
