How Much Does a Walk-In Tub or Shower Conversion Cost?
A walk-in tub installed costs $2,500-$13,500. Converting a tub to a walk-in shower costs $3,500-$15,000, averaging around $9,000 for a full walk-in shower. The gap between the low and high end of each range comes down to materials and how much plumbing or structural work your bathroom needs.
The price range
$2,500–$13,500
Materials alone run $1,500-$8,500; the rest is installation labor and any needed plumbing work.
$3,500–$15,000
A basic prefab acrylic conversion runs $2,500-$5,000; a mid-range tiled shower with a glass enclosure runs $4,000-$8,000; a full custom or curbless build reaches the top of the range.
What moves the price up or down
- Prefab vs. custom materials. An acrylic surround kit is dramatically less expensive than custom tile, though tile offers more design flexibility and, done well, can look more integrated with the rest of the bathroom.
- Plumbing relocation. If the new fixture needs the drain or water lines moved (common when switching from a tub’s drain location to a different shower footprint), expect a real cost increase.
- Curbless/zero-threshold design. Removing the entry step requires re-sloping the floor, which adds cost — see our curbless shower guide (opens in a new tab) for that breakdown specifically.
- Structural or water damage found during demolition. Older bathrooms sometimes reveal subfloor rot or outdated plumbing once walls are opened, which isn’t foreseeable until the project starts.
What’s typically included and excluded
Most quotes in this range include the fixture itself, basic plumbing connections, and standard labor. They typically exclude: extensive tile work beyond the shower surround, a new vanity or toilet if you’re doing a broader remodel, and permit fees (usually $50-$300 separately). Ask your contractor to itemize these explicitly before you compare quotes — two bids that look far apart sometimes differ mainly in what’s included, not in the underlying work.
Getting an accurate local quote
Get at least three quotes, and ask each contractor to specify: whether they’re proposing prefab or custom materials, whether any plumbing relocation is needed, and their timeline. Contractors with specific aging-in-place or accessibility experience (look for a CAPS certification (opens in a new tab)) are more likely to flag accessibility details — like door swing clearance or grab bar blocking — that a general remodeler might miss.
How to pay for it
If the modification is medically necessary, it may qualify for Medicaid HCBS waiver coverage, a VA HISA grant if the person is a veteran, or a medical-expense tax deduction. See our financial assistance guides (opens in a new tab) for how each program works and how to apply.
Frequently Asked Questions
Why is there such a wide price range for these conversions?
The low end typically covers a straightforward swap using prefabricated, acrylic components in a bathroom that doesn't need plumbing relocated. The high end covers custom tile work, moved plumbing lines, structural floor changes for a curbless design, or a premium walk-in tub with therapeutic features like jets or a heated seat.
Does insurance ever cover a walk-in tub or shower conversion?
Standard health insurance and Original Medicare generally do not cover these as home modifications. Some Medicare Advantage plans offer limited home-modification allowances, and Medicaid HCBS waivers cover bathroom accessibility modifications in many states for qualifying individuals — see our financial assistance guides for details.
