How much does it cost to replace a bathtub?
A straight bathtub swap — same location, same size, no layout changes — typically runs $1,500–$5,000 installed, depending on the tub material and whether tile surrounds need replacing. Converting that same space to a walk-in shower costs $3,500–$9,000 for an acrylic system or $10,000–$15,000 for custom tile.
The cheapest path is keeping the plumbing exactly where it is. Moving the drain even 12 inches adds $500–$1,500 to the job. If your current tub and tile are in acceptable shape, reglazing ($300–$600) buys another 5–10 years for a fraction of replacement cost.
What drives the cost of bathtub replacement
Alcove tub, same footprint (most common)
$1,500 – $3,500How to tellStandard 60-inch tub in a three-wall alcove; replacing with same size fiberglass or acrylic unit
The fixDrop-in replacement — plumber disconnects and reconnects drain; surround tiles may need some replacement
Tile surround replacement
Acrylic surround: add $500 – $1,500; ceramic tile: add $1,500 – $4,000How to tellCurrent tile is chipped, moldy, or you want a new look; can't just swap the tub without addressing the surround
The fixTile demo and retile adds scope; acrylic surrounds are faster/cheaper than custom tile
Freestanding or soaking tub upgrade
$2,500 – $8,000+ depending on tub and plumbing scopeHow to tellMoving from a basic alcove tub to a freestanding or deep soaking tub for a primary bathroom upgrade
The fixRequires floor drain relocation and often a wall-mounted or freestanding faucet — more plumbing work
Tub-to-shower conversion (acrylic)
$3,500 – $9,000How to tellNo longer using the tub regularly; want more shower space or easier daily access
The fixDemo tub, re-waterproof floor, install prefab acrylic shower pan and walls — 1–3 day job
Substrate damage discovered during removal
Add $500 – $2,500How to tellWhen the old tub comes out, rotted subfloor or wall studs are found — especially in older homes or after past leaks
The fixMust be addressed before any new installation; cost depends on extent
Try this first (before you pay anyone)
- Check if reglazing makes sense first: a professional reglaze ($300–$600) can make a chipped, stained, or dated tub look new and buy 5–10 years. Worth it if the tub is structurally sound and you just want a fresh look.
- Probe the floor around the tub with a screwdriver — soft spots mean subfloor damage that will need to be addressed before any replacement.
- Measure your tub alcove before buying any replacement unit — standard is 60 x 32 x 18 inches, but older homes sometimes have 54-inch or 66-inch alcoves that need non-standard units.
Unlock the hiring checklist
Use this before you call a bath remodel, so you know what to ask and what to avoid.
Call a pro when…
- Any tub replacement involving disconnecting and reconnecting the drain requires a licensed plumber
- If you find soft flooring or water-stained walls when you inspect the current tub area — subfloor and moisture work needs to happen before the new tub goes in
- You're converting tub to shower — waterproofing a shower floor is not a DIY job if done right; a failed shower pan causes extensive subfloor damage
Repair or replace?
If the tub is chipped, stained, or scratched but structurally sound, reglazing ($300–$600) is the right answer — not replacement. If the tub has cracked fiberglass, rusted cast iron, or the surrounding substrate is wet-damaged, replacement is the correct call. The 50% rule: if the combined cost of reglaze plus tile/surround repair would exceed half the replacement cost, replace. If keeping the tub location saves a plumber's relocation fees, that savings alone often makes replacement worthwhile.

Related questions
How long does bathtub replacement take?
A straight swap with no tile work takes 1–2 days. Demo, subfloor repair if needed, new surround, and new tub takes 3–5 days. A full tub-to-shower conversion with custom tile runs 5–10 days.
Can I keep my tub and just regrout and recaulk?
Yes — and you should try this first. Regrout ($150–$400) and recaulking corners ($50–$150) can extend a tub's life significantly if the underlying structure is sound. The tell: if you clean grout and it immediately looks moldy again, or if the tiles flex when you push them, there's moisture behind the wall that needs more than cosmetic work.
What's the cheapest way to replace a bathtub?
A basic fiberglass tub with acrylic surround in a like-for-like swap is the least expensive option — often $1,500–$2,500 installed. Keeping the drain and valve in exactly the same position, choosing a standard 60-inch alcove tub, and doing the project without tile (using a prefab surround) hits the low end of the range.
Does replacing a bathtub add home value?
Replacing a functional tub usually returns 50–70% of the cost at resale — not a strong financial argument alone. However, a failed or clearly deteriorated bathroom can actively hurt a home sale. If your bathroom is dated but functional, cosmetic updates (reglaze, new fixtures, fresh grout) typically give better ROI than full replacement before a sale.
