Cross-checked against three published sources for this project. Sources used for this page: the Angi bathtub replacement cost guide, This Old House's bathtub installation cost guide and HomeGuide's bathroom remodel cost data (bathtub replacement line).

Cost by scope
| Scope | Typical cost | What it includes |
|---|---|---|
| Standard alcove tub, like-for-like swap | $1,200 – $2,800 | The simple end: the new tub sits where the old one was and the plumbing stays put — This Old House's itemized standard replacement totals $2,110, and HomeGuide's bathroom data runs bathtub replacement at $800–$4,600 across scopes |
| Standard replacement with a new surround — the typical job | $1,800 – $4,500 | The typical band on this page: a new alcove tub with faucet, drain and a renewed surround in the same footprint — Modernize runs replacements at $1,500–$6,500 with most homeowners near $3,500, and Angi's full guide range starts at $2,104 |
| Freestanding, jetted, walk-in or moved plumbing | $4,500 – $10,000+ | Angi's guide averages $5,929 across all its projects and runs to $9,757 at the top; freestanding plumbing, a subfloor rebuild ($300–$800) or moving the drain ($400–$1,900) are the spend at this tier |
Where the money goes
| Part of the job | Share | Note |
|---|---|---|
| Installation labor & plumbing | 35–50% of total | Labor is the largest line on a like-for-like swap: Angi prices labor at $100–$2,000 depending on access and plumbing work, Modernize puts labor at about 55% of its typical project, and moving the plumbing adds $400–$1,900 on its own |
| The tub itself | 20–35% | A standard alcove tub runs $200–$800 for the unit in Angi, and This Old House's itemized job prices its tub at $454 — material (acrylic, enamelled steel, cast iron) and format (alcove, freestanding, walk-in) move this line more than size does |
| Surround & waterproofing | 15–25% | Angi prices a surround at $500–$2,000 on top of the tub work and This Old House prices a surround installed at $1,100–$2,100; a tired surround replaced with the tub is the common reason a swap prices as this page's typical tier |
| Removal, disposal & parts | 8–15% | Angi prices removal and disposal at $150–$4,500 across tub types — a fiberglass tub out is $50–$100, cast iron $300 and up — and This Old House's itemized total carries $230 of removal plus the drain, overflow and spout parts |
What moves the price most
Whether the plumbing moves is the bathtub budget. A like-for-like swap keeps the drain and supplies where they are, and This Old House's itemized standard job totals $2,110 on exactly that basis; Angi prices moving plumbing at $400–$1,900, and a layout change prices as plumbing work with a tub attached. The old tub's material is the second lever: removal runs $150–$4,500 across Angi's table because a fiberglass or acrylic tub cuts out in pieces ($50–$100) while a cast-iron tub comes out at $300 and up, sometimes in sections, with the wall opened to free it. The surround is the third: a tub-only swap keeps the old surround and prices at the low tier, but most old tubs are replaced because the surround has failed with them — Angi prices a surround at $500–$2,000 extra, and that single decision is the difference between this page's first and second tiers. Finally, what is under the tub decides the surprise line: subfloor preparation runs $300–$800 in Angi, permits $10–$500 where the plumbing is touched, and both are found after the old tub is out — which is why quotes for this job carry wider ranges than the tub's price suggests.
Worked example: how a typical bathtub replacement budget breaks down
A typical job: one standard alcove tub replaced in the same spot — old tub removed and disposed of, new tub set level and connected to the existing drain, new faucet and drain trim, surround renewed and sealed. The budget below totals $2,700 — the "most homeowners pay around" figure from the top of this page — split using this page's own cost breakdown. It shows how a real quote at that level is usually composed; every line is built from the ranges on this page, and it is an illustration, not a quote for your project.
| Line item | Example budget |
|---|---|
| New alcove tub | $700 |
| Labor and plumbing hookup | $1,100 |
| Surround and waterproofing | $550 |
| Removal, disposal and parts | $350 |
| Total | $2,700 |
What most people get wrong
- Pricing the job off the tub alone — the unit is 20–35% of the total; labor, surround and removal are the rest of the quote, and a $400 tub does not make a $400 job.
- Keeping a failed surround to save money — most old tubs are replaced because water got behind the surround; a new tub against a rotten wall is the same job bought twice.
- Assuming the old tub comes out easily — a cast-iron tub is $300 and up to remove in Angi against $50–$100 for fiberglass, and it is discovered by looking, not by hoping.
- Skipping the subfloor check while the tub is out — subfloor prep is $300–$800 in Angi, and the one moment it is cheap to fix is the day the old tub is standing in the yard.
Costs in your city
Bathtub replacement pricing follows plumber rates and housing age more than tub prices — the units are national, but the labor-and-plumbing line (35–50% of the total) is local, and metros with high plumber rates sit at the top of it. Older housing stock changes the job itself: cast-iron tubs, tired surrounds and soft subfloors are all age findings, so a pre-war bathroom prices nearer the top of the band than a 15-year-old one in the same city. Permits join in where the plumbing is touched (Angi prices them at $10–$500). Ask each bidder whether the quote assumes the plumbing stays put, what the surround scope is, and what a subfloor repair would add if one is found; on a tub swap, those three answers are the comparison.
Frequently asked questions
How much does it cost to replace a bathtub?
About $1,800–$4,500 is the typical band on this page for a standard alcove replacement with a renewed surround, with most projects landing around $2,700. This Old House's itemized standard job totals $2,110, Modernize puts most homeowners near $3,500, and Angi averages $5,929 because its average includes freestanding, jetted and walk-in work.
Why do bathtub replacement prices disagree so much between guides?
Scope, mostly. This Old House itemizes a standard like-for-like job at $2,110; Angi's $5,929 average is drawn across every tub type it tracks, including walk-in and freestanding work at $4,500–$10,000+. HomeGuide's bathroom table runs $800–$4,600 for the replacement line alone. All three are describing real jobs — they are not describing the same job.
How much does it cost to remove an old bathtub?
Angi prices removal and disposal at $150–$4,500 depending on the tub: a fiberglass tub comes out at $50–$100, while cast iron starts at $300 and climbs when it has to be broken up or the wall opened. This Old House's itemized job carries removal at $230.
Does replacing a bathtub require moving the plumbing?
Not on a like-for-like swap — the new tub connects to the existing drain and supplies, which is what keeps the job in the lower tiers. Moving the drain or supplies for a different size, format or position adds $400–$1,900 in Angi, and is the single most common reason a replacement quote leaves the typical band.
Can I replace a bathtub myself?
The guides price labor at $100–$2,000, so the DIY saving is real, but the job's hard parts are not the fitting — they are getting a rigid, heavy old tub out (cast iron especially), setting the new tub dead level, and aligning the drain and overflow so they seal first time. A slow drain leak under a new tub is the classic DIY cost, and it is found months later, in the ceiling below.
