Medicare covers walk-in showers only if a doctor orders them as medical equipment, and only through Medicare Part B durable medical equipment (DME) benefit — not as a home modification

Medicare will not pay to install a walk-in shower as a bathroom upgrade or accessibility feature. It will pay for a walk-in tub — a bathing device with a door you can open and close — if your doctor writes an order saying you need it for a medical reason, such as mobility problems, arthritis, or balance issues that make stepping over a tub rim unsafe. The tub itself must come from a Medicare-approved DME supplier, and Medicare typically covers 80 percent of the approved amount after you meet your Part B deductible.

A walk-in shower — a permanent fixture built into your bathroom — is considered a home modification or renovation, not medical equipment. Medicare does not cover home modifications under any circumstance. If you want a walk-in shower instead of a traditional tub, you pay for the construction and installation yourself, or you may find funding through state or local aging programs, Medicaid (which varies by state), or non-profit home repair grants.

Key Takeaways

  • Medicare Part B covers walk-in tubs (portable bathing devices with doors) if your doctor orders them for a medical reason, but does not cover permanent walk-in shower installations.
  • You need a written order from your doctor and must use a Medicare-approved DME supplier to have the cost covered.
  • Medicare pays 80 percent of the approved amount for a walk-in tub after you meet your Part B deductible; you pay the remaining 20 percent.
  • Medicaid, state aging programs, and non-profit home repair organizations may cover walk-in shower construction in some states, though rules vary widely.
  • Grab bars, shower chairs, and non-slip mats are often covered by Medicare if medically necessary, and cost far less than a walk-in tub or shower.

The difference between a walk-in tub and a walk-in shower

A walk-in tub is a freestanding bathing device with a watertight door on the side. You open the door, step inside, close and lock the door, and then water fills the tub. When you are done, you drain the water and open the door to step out. Walk-in tubs are portable — they can be moved or removed — and Medicare classifies them as durable medical equipment.

A walk-in shower is a permanent bathroom fixture: a shower stall with a low or no threshold, built into your home's plumbing and structure. Once installed, it cannot be removed without construction work. Because it is a permanent alteration to your home, Medicare treats it as a home modification, not medical equipment, and does not cover it.

The practical difference matters for your wallet. A walk-in tub covered by Medicare costs you roughly 20 percent of the approved price after your deductible. A walk-in shower costs you the full price of construction, materials, and labor — typically $3,000 to $8,000 or more, depending on your bathroom layout and local labor costs.

How to get Medicare to cover a walk-in tub

The process has four steps: your doctor must order it, you must choose a Medicare-approved supplier, the supplier must get approval from Medicare before delivery, and Medicare pays the supplier directly.

Step 1: Get a written order from your doctor. Your primary care doctor or a specialist (such as a rheumatologist, neurologist, or orthopedic surgeon) must write an order stating that you need a walk-in tub for a medical reason. Common reasons include severe arthritis, balance disorders, recent surgery or injury, neurological conditions, or mobility limitations that make stepping over a tub rim unsafe. The order must be specific: it should say "walk-in tub" or "walk-in bathtub," not just "bathing equipment." If your doctor is unsure whether to write the order, ask them directly whether they think a walk-in tub would reduce your fall risk or help you bathe safely.

Step 2: Find a Medicare-approved DME supplier. Not all medical supply companies are Medicare-approved. Call your Medicare plan (the number is on your insurance card) and ask for a list of approved suppliers in your area who carry walk-in tubs. You can also search the Medicare supplier directory at dmepos.cms.gov. Contact at least two suppliers to compare prices, delivery timelines, and warranty terms — Medicare approves the price, but suppliers may offer different models or installation options.

Step 3: The supplier submits for prior approval. Before ordering your tub, the supplier must send your doctor's order to Medicare and request approval. This step is called prior authorization. Medicare reviews the order to confirm it is medically necessary. This usually takes 5 to 10 business days. Do not order or pay for the tub until Medicare approves it — if Medicare denies the request, you are responsible for the full cost.

Step 4: Medicare pays the supplier; you pay your share. Once approved, Medicare sends payment directly to the supplier. You pay your 20 percent coinsurance (after meeting your Part B deductible) and any amount above Medicare's approved price. Ask the supplier upfront what your out-of-pocket cost will be.

What Medicare actually covers for bathroom safety

Walk-in tubs are expensive and not always the right solution. Before pursuing one, know what else Medicare covers for bathroom safety — often at much lower cost.

Grab bars are covered if your doctor orders them. Medicare pays 80 percent of the cost (after your deductible) for bars installed in your bathroom to help you stand, balance, or transfer safely. A set of grab bars costs $100 to $300 installed, so your out-of-pocket cost is typically $20 to $60.

Shower chairs and bath benches are covered if medically necessary. These portable seats let you sit while bathing, reducing fall risk. They cost $50 to $200, and Medicare covers 80 percent.

Non-slip bath mats and adhesive strips are sometimes covered, though coverage varies. Ask your doctor to order them if you have balance problems or a history of falls.

Raised toilet seats and toilet safety frames are covered and help people with mobility or balance issues. They cost $30 to $150.

If you have limited mobility but do not need a full walk-in tub, combining grab bars, a shower chair, and a raised toilet seat often solves the problem at a fraction of the cost and without permanent home modification.

When Medicare denies coverage for a walk-in tub

Medicare may deny your request if your doctor's order does not clearly state a medical reason, if the supplier is not Medicare-approved, or if Medicare decides the tub is not medically necessary for your condition. Common reasons for denial include: the order says "for convenience" rather than for a medical condition; your doctor did not write the order (a nurse or therapist did); or your condition does not meet Medicare's threshold for medical necessity.

If Medicare denies your request, you have the right to appeal. Ask your supplier or your doctor's office to file an appeal on your behalf within 180 days of the denial letter. Include any additional medical records, test results, or a letter from your doctor explaining why the tub is medically necessary. Many appeals succeed because the initial order lacked detail.

If your appeal is denied, you can pay out of pocket for the walk-in tub, or explore other funding sources such as Medicaid (if you may have access to), state aging programs, or non-profit home repair grants in your area.

Other ways to pay for a walk-in shower

If you want a permanent walk-in shower and Medicare will not cover it, several other sources may help, though availability depends on where you live.

Medicaid covers home modifications in some states if you are low-income and the modification is medically necessary. Rules vary widely — some states cover walk-in showers, others do not. Contact your state Medicaid office to ask whether bathroom modifications are covered under your plan.

State and local aging programs sometimes fund home safety modifications for older adults. Contact your local Area Agency on Aging (find yours at eldercare.acl.gov) to ask whether they have grants or loans for bathroom renovations.

Non-profit home repair organizations in your area may offer low-cost or volunteer labor for home safety modifications. Search for "home repair information" or "aging in place grants" in your county or state.

Reverse mortgages allow homeowners 62 and older to borrow against home equity. Some people use the funds for home modifications, though this reduces the equity available to heirs and carries fees and interest.

Home equity loans or lines of credit let you borrow against your home's value to pay for renovations. Interest rates and terms vary by lender and your credit score.

Frequently Asked Questions

Can my doctor order a walk-in shower instead of a walk-in tub?

No. Medicare only covers walk-in tubs as durable medical equipment. A permanent walk-in shower is a home modification, and Medicare does not cover home modifications under any circumstance, regardless of medical necessity or doctor's order. If you want a walk-in shower, you must pay for it yourself or find funding through Medicaid, state programs, or non-profits.

What if I cannot afford the 20 percent coinsurance for a walk-in tub?

If you have a Medigap or Medicare Advantage plan, it may cover some or all of your coinsurance. Check your plan documents or call your plan's customer service line. If you are low-income, you may may have access to for Medicare Savings Programs, which help pay your Part B premiums, deductibles, and coinsurance. Contact your state Medicaid office to learn whether you may have access to.

How long does it take to get a walk-in tub approved and delivered?

Prior authorization typically takes 5 to 10 business days. Delivery and installation take another 1 to 4 weeks, depending on the supplier and whether your bathroom needs plumbing work. Plan for 4 to 8 weeks total from the time your doctor writes the order to the time the tub is installed.

Do I need to pay for installation, or does Medicare cover that?

Medicare covers the tub itself but not installation labor. You pay for installation separately, either to the supplier or to a plumber you hire. Installation costs vary but typically range from $500 to $2,000 depending on your plumbing setup. Ask the supplier what installation is included in their price.

What if my bathroom is too small for a walk-in tub?

Walk-in tubs require space — typically at least 30 inches of clearance on the side where the door opens. If your bathroom cannot fit one, talk to your doctor about other options: grab bars, a shower chair, or a raised toilet seat may solve your safety concerns without requiring a tub. If you want a walk-in shower, you would need to discuss bathroom renovation with a contractor.
