Start with a real number
You cannot plan a family budget around a guess. Aging Safely Baths quotes fully installed walk-in tubs at roughly $15,250 to $20,000 after current promotions, itemized in writing, and offers supply-only delivery for families who already have a trusted contractor. Other companies price very differently, and some only quote during an in-home sales visit. Whoever you call, ask for a written, itemized quote that shows removal of the old tub, plumbing, electrical, wall finishing and any water heater work.
For what drives the price up or down, see the walk-in tub cost guide on AgingSafelyBaths.com.
Splitting the cost among family members
There is no standard formula, only what feels fair to your family. Three approaches come up most:
- Equal shares. Simple and easy to explain. It can strain a sibling with a smaller income.
- Shares by ability to pay. Fairer on paper, but agree on it out loud so nobody feels judged.
- Money plus time. The sibling who lives nearby and handles appointments, installation day and ongoing help contributes time instead of some cash. NIA's caregiving guidance stresses that the primary caregiver needs support from the others, and this is one concrete way to give it.
Whatever you choose, put it in a short email everyone replies to. Decide whose name goes on the contract and who pays the deposit, because those choices can matter for taxes, as the next section explains. Keep every invoice and receipt in one shared folder.
If your parent might need Medicaid for long-term care, talk to an elder law attorney before moving money around. Medicaid looks back at transfers of assets made before an application, and how a family pays for a home change can affect eligibility later.
The tax rule: medical home improvements
IRS Publication 502 (Medical and Dental Expenses, for 2025 returns) explains when a home improvement counts as a deductible medical expense. Here is what it says, in plain terms.
The main test is medical purpose
Under the heading "Capital Expenses," Publication 502 says you can include in medical expenses amounts you pay for special equipment installed in a home, or for improvements, if their main purpose is medical care for you, your spouse or your dependent.
The value rule
If the improvement raises the value of the home, you reduce the cost by that increase and only the rest counts. If it does not raise the value, the entire cost can count. Publication 502 lists changes made to accommodate a home to a disabled condition that generally do not raise its value, including "installing railings, support bars, or other modifications to bathrooms," widening doorways, and adding grab bars anywhere. It also says only reasonable costs count, and that extra cost for personal, architectural or aesthetic reasons does not.
What about a doctor's note?
You may have read that the deduction requires a doctor's recommendation. Publication 502's capital expense section does not state that as a requirement; the test is the main purpose of the work. It does use an example where an improvement is made "on the doctor's advice," and a doctor's letter is the clearest proof of medical purpose if the IRS ever asks. Get one, date it before the work, and keep it with the invoice.
The two limits that decide whether it helps
- You must itemize deductions on Schedule A. If you take the standard deduction, this rule does not help that year.
- Only the part of total medical expenses above 7.5% of adjusted gross income counts. A large one-time project can push a household over that line in the year it is paid.
When an adult child pays
Publication 502 lets you include medical expenses you pay for a dependent, and a parent can qualify if, among other tests, you provided over half of their support for the year. For medical expense purposes there is an exception to the dependent income test, so a parent with gross income of $5,200 or more in 2025 can still count. When several siblings together provide more than half of a parent's support but nobody provides more than half alone, they can sign a multiple support agreement so one of them is treated as the supporter; that person can then include the medical expenses they actually paid.
This is exactly the kind of situation where the details matter, including whose home it is and who paid. Treat this section as a list of questions for a tax professional, not as advice on your return.
| Rule | What it means for a walk-in tub |
|---|---|
| Main purpose is medical care | Document the medical need, ideally with a doctor's letter |
| Cost reduced by any increase in home value | Bathroom modifications for a disability are listed as generally not adding value |
| Reasonable cost only | Upgrades chosen for looks or luxury may not count |
| Itemize, and only above 7.5% of AGI | Run the numbers before assuming a benefit |
| Dependent parent, over half of support | A child paying for a parent may qualify; siblings can use a multiple support agreement |
Long-term care insurance
If your parent has a long-term care policy, read it before you assume it helps. The National Institute on Aging describes these policies as covering services and support for people who need help with daily activities, in settings that can include the person's home. That usually means paying for care, such as an aide who helps with bathing, not for remodeling the bathroom. Some policies contain language about home modifications or alternate plans of care; others do not. Call the insurer, ask whether a bathroom modification is a covered benefit under that policy, and get the answer in writing.
Two related tax points from Publication 502:
- Premiums for a qualified long-term care policy can count as medical expenses, up to an age-based limit per person. For 2025 the limit is $4,810 for ages 61 to 70 and $6,020 for 71 and older.
- A policy that is "tax qualified" pays benefits when the insured is chronically ill, which generally means unable to perform at least two activities of daily living, such as bathing, without substantial help for at least 90 days, or needing substantial supervision because of severe cognitive impairment.
Medicare, Medicaid and VA help
Medicare
Original Medicare's durable medical equipment benefit covers items like walkers, wheelchairs and commode chairs. A walk-in tub is a home modification, and it is not on that list. Some Medicare Advantage plans offer extra benefits for home and bathroom safety items; check the plan's Evidence of Coverage or call the plan. Aging Safely Baths has a fuller breakdown of Medicare and walk-in tubs.
Medicaid
Some states fund home modifications through Medicaid home and community-based services waivers, usually for people who would otherwise need nursing-home-level care. Rules and waiting lists vary widely. See the state-by-state Medicaid waiver table, and call the Eldercare Locator at 800-677-1116 to reach your parent's local Area Agency on Aging.
Veterans: the VA HISA grant
The VA's Home Improvements and Structural Alterations (HISA) grant pays for medically necessary changes to a veteran's primary home. According to VA Prosthetic and Sensory Aids Service, the lifetime benefit is up to $6,800 for a service-connected condition (or for a veteran rated at least 50% service-connected) and up to $2,000 otherwise. The application needs a prescription written or approved by a VA physician.
Read the fine print before choosing a product. VA lists roll-in showers as an example of an eligible bathroom change, and it excludes "spa/hot tubs/Jacuzzi type tubs." A jetted walk-in tub is unlikely to qualify; a plain soaking tub or a shower conversion is a question for the local Prosthetics office. Aging Safely Baths explains the paperwork in its VA HISA guide.
Financing and other options
- Company financing. Aging Safely Baths offers financing options; compare the rate with a credit union or home equity line.
- Your parent's own savings. NIA notes that many older adults pay for care-related costs with personal savings, pensions or investment income.
- Reverse mortgage. Available to homeowners 62 and older, but complex. NIA advises talking to an expert first.
- Local programs. Some Area Agencies on Aging, nonprofits and utility programs help with home repairs or modifications. The Eldercare Locator can point you to them.
Questions families ask
Is a walk-in tub tax deductible?
It can be, as a medical expense, if its main purpose is medical care. IRS Publication 502 lets you include special equipment or home improvements whose main purpose is medical care, reduced by any increase in the home's value. You must itemize, and only total medical expenses above 7.5% of adjusted gross income count. Ask a tax professional about your situation.
Does the IRS require a doctor's prescription for a home modification deduction?
Publication 502 does not list a doctor's recommendation as a requirement for capital expenses. The test is whether the main purpose is medical care. A letter from your parent's doctor explaining why the change is medically needed is still the best evidence to keep with your records.
Can I deduct a walk-in tub I paid for in my parent's home?
Possibly, if your parent qualifies as your dependent for medical expense purposes. Publication 502 lets you include medical expenses you pay for a parent when you provide over half of their support, and a gross income exception means their own income does not automatically rule this out. Siblings can use a multiple support agreement. Confirm with a tax professional before you pay.
Will long-term care insurance pay for a walk-in tub?
Usually long-term care insurance pays for care services, such as help with bathing, rather than for remodeling. Some policies have wording that may cover home modifications or alternate care plans. Read the policy and ask the insurer in writing before you buy anything.
Does the VA HISA grant cover walk-in tubs?
HISA pays for medically necessary home changes, up to $6,800 or $2,000 for life depending on eligibility, and needs a prescription from a VA physician. VA lists roll-in showers as an example and excludes spa, hot tub and Jacuzzi-type tubs, so jetted tubs are unlikely to qualify. Ask your local VA Prosthetics office before choosing a product.
How do siblings usually split the cost?
Common approaches are equal shares, shares based on income, or a cash and time split where the sibling who lives nearby contributes care instead of money. Whatever you choose, write it down, decide whose name goes on the contract, and keep every receipt.
