Based on aggregated data, bathtub replacement costs $1,500 to $8,000, with a typical project landing near $2,500. Within that total, materials account for roughly $400 to $4,000 and labor for $500 to $3,500, over a typical duration of 1 to 3 days.
Most people searching this phrase want the number at the bottom of that range, and for a genuinely straightforward job they get it: a like-for-like acrylic tub dropped into the same alcove, on the same drain, behind the same surround, lands at $1,500 to $3,000 all in. That is the job the price guides quote.
The reason the range runs to $8,000 is that a bathtub is not a freestanding object you lift out. It is a component the bathroom was built around. Understanding a tub quote is mostly a matter of counting how many of the things built around it have to come off before the tub can leave the room.
The Straightforward Swap — and the Five Ways It Stops Being One
| Scope | What it involves | Typical cost |
|---|---|---|
| Like-for-like swap | Same size tub, same drain, surround survives | $1,500–$3,000 |
| Swap + new surround | Surround destroyed on removal, replaced with a 3-piece panel kit | $2,200–$4,200 |
| Swap + tiled surround rebuild | Tile, backer board, waterproofing on three walls | $3,000–$6,000 |
| Swap + drain or valve relocation | Floor or wall opened to move the plumbing | $2,500–$5,500 |
| Swap + subfloor repair | Rot found under the old tub when it comes out | $2,000–$5,000 |
| Freestanding or heavy tub | Floor-mounted filler, framing check, 2–3 person set | $3,500–$8,000 |
Every row after the first contains the same tub. The difference between $1,500 and $8,000 is almost never the tub — it is how much of the room came apart to get the old one out and how much of it has to go back.
The Alcove Problem — Why the Tub Comes Out Through the Wall
A standard alcove tub sits in a three-walled recess, and it is installed before the walls are finished. Its top edge is a nailing flange, screwed to the studs, and the surround — tile, backer board, or a three-piece acrylic kit — is then built down over that flange so water runs onto the tub instead of behind it.
That sequence is what makes removal expensive, because it only runs one way. The flange is under the wall. To free the tub, the bottom 6 to 12 inches of the surround has to come off, which on a tiled wall means breaking tile and usually the backer board behind it. Then the tub still has to physically leave: a 60-inch tub in a bathroom with a 30-inch door and a corner in the hallway does not always pivot out, which is why a fiberglass or acrylic tub is normally cut into two or three pieces with a reciprocating saw rather than carried, and why the door casing occasionally comes off first.
None of that is visible in a tub’s sticker price, and it is routinely the largest single line on the invoice.
| Removal and repair line | Typical cost |
|---|---|
| Cut out and haul a fiberglass or acrylic tub | $60–$250 |
| Break up and haul a cast iron tub | $200–$600 |
| Remove the bottom courses of a tiled surround | $150–$400 |
| Full tiled surround demolition (3 walls) | $300–$800 |
| Drywall and backer board repair around the alcove | $200–$700 |
| Remove and reset door casing to get the tub out | $75–$250 |
| Debris disposal (cast iron is charged by weight) | $100–$400 |
A useful way to read a quote: the tub, the valve trim and the drain assembly are a few hundred dollars of catalogue items. Everything else on the page is the alcove.
Cost by Tub Type
| Tub type | Tub only | Installed total | Notes |
|---|---|---|---|
| Alcove (standard three-wall) | $200–$1,000 | $1,500–$3,000 | The default; the cheapest replacement path |
| Drop-in (set into a deck) | $400–$1,800 | $2,000–$5,000 | Deck framing and deck surface priced separately |
| Undermount | $600–$2,200 | $2,500–$5,500 | Deck material is cut and finished around the rim |
| Soaking tub (deep, alcove or freestanding) | $600–$3,000 | $2,500–$6,500 | Deeper and heavier when full; hot water volume matters |
| Freestanding | $800–$4,000 | $3,500–$8,000 | Floor-routed supply and drain; often a floor-mounted filler |
| Clawfoot (cast iron or acrylic) | $800–$4,000 | $3,000–$8,000 | Exposed supply lines, feet, and floor loading |
| Corner tub | $700–$3,000 | $3,000–$7,000 | Non-standard footprint; framing often modified |
| Whirlpool / jetted | $700–$4,000 | $3,500–$8,000 | Needs a dedicated GFCI circuit and an access panel |
| Air-jet tub | $1,000–$4,000 | $4,000–$8,000 | Same electrical requirement, quieter, easier to keep clean |
| Walk-in tub | $2,500–$4,000 | $5,500–$8,000 | Door seal, low threshold, powered features |
Alcove is the cheap row for a structural reason, not a market one: the plumbing is already in the wall behind it, the drain is already at the correct end, and the tub is hidden on three sides so its finish only has to look right on one. Every other type either moves the plumbing, adds a deck, adds electrical, or exposes more of the tub to view.
Cost by Material
| Material | Tub only | Installed total | Weight (empty) | Lifespan |
|---|---|---|---|---|
| Fiberglass (gel-coated) | $200–$800 | $1,500–$2,600 | 60–70 lb | 10–15 years |
| Acrylic | $400–$1,500 | $1,600–$3,400 | 70–100 lb | 15–30 years |
| Porcelain-enameled steel | $300–$900 | $1,700–$3,000 | 100–150 lb | 20–30 years |
| Cast iron (porcelain-enameled) | $600–$2,000 | $3,000–$5,500 | 300–500 lb | 40–70 years |
| Cultured marble | $700–$2,500 | $2,500–$5,000 | 200–350 lb | 20–30 years |
| Stone resin / solid surface | $1,500–$4,000 | $4,000–$8,000 | 200–400 lb | 30–50 years |
| Copper | $2,000–$4,000 | $4,500–$8,000 | 100–200 lb | 50+ years |
The four materials that account for nearly every replacement are the top four rows, and they split cleanly into two pairs.
Fiberglass and acrylic are the light pair. Fiberglass is chopped glass fiber in polyester resin with a thin gel-coat surface; acrylic is a solid acrylic sheet vacuum-formed over a fiberglass backing. Acrylic costs a few hundred dollars more, holds its gloss far longer, and is repairable — a scratch or a chip in acrylic can be sanded and polished because the color runs through the sheet, while the same damage on fiberglass goes through the gel coat and into a dull grey composite. Both are light enough for one person to carry, which keeps their labor line at the bottom of the $500 to $3,500 range.
Porcelain-enameled steel and cast iron are the heavy pair — the same glass enamel finish over two very different substrates. Steel is a stamped shell at 100 to 150 pounds: hard-wearing, but it flexes and rings underfoot, and enamel over a flexing panel is where chips start. Cast iron is the same enamel over a poured iron shell that weighs 300 to 500 pounds empty and holds heat for a long soak.
That weight is a real labor line and not a footnote. A cast iron tub is a two- to three-person set — one person cannot walk it up a staircase, through a doorway, and lower it into an alcove without dropping it — and it typically adds $200 to $600 to the installation over an acrylic tub of identical dimensions. Getting the old cast iron tub out costs money in the same way: it is either broken up with a sledgehammer under a tarp and carried out in pieces, or it goes out whole, which is the reason a cast iron removal runs $200 to $600 where an acrylic one runs $60 to $250. Disposal is often weighed, and 400 pounds of iron is not a rounding error at the transfer station.
Materials vs Labor: Where the Money Goes
| Component | Low | Mid | High | Share of a typical project |
|---|---|---|---|---|
| Materials (tub, drain assembly, valve trim, surround, backer, sealant) | $400 | $1,000 | $4,000 | ~40% |
| Labor (demolition, disposal, plumbing, set, surround, seal) | $500 | $1,500 | $3,500 | ~60% |
| Total project | $1,500 | $2,500 | $8,000 | 100% |
Labor is about 60 percent of a typical replacement, and the hours are not where people expect them. Setting a tub is a fast operation — level it, bed it in mortar or on its feet, connect the drain, connect the overflow, secure the flange. Almost the entire labor line is on either side of that moment: taking the surround off, cutting the old tub out, hauling it, inspecting what was under it, and then rebuilding three walls of surround down over the new flange, which is a tile job or a panel job in its own right.
The 1-to-3-day duration is a sequencing fact, not a difficulty one. Day one is demolition and removal. The tub is set and the plumbing connected. Then the surround goes back — and if it is tiled, thinset and grout each need a cure window before the next step, which is why a tiled alcove is quoted across days rather than hours.
Freestanding and Soaking Tubs — Floor Structure and the Filler
A freestanding tub changes two things that the alcove hid.
The plumbing comes up through the floor. In an alcove, the supply and the waste run in the wall the tub is pushed against. A tub standing in the open has neither, so the drain is rerouted to a point under the tub and the supply is brought up through the floor. That is a $400 to $1,900 line depending on what is under the bathroom — an open basement ceiling is cheap, a slab or a finished ceiling below is not. The tap frequently becomes a floor-mounted filler tower at $400 to $1,200 for the fixture alone, because there is no wall to hang a spout on.
The floor structure carries a concentrated load. A cast iron soaking tub at 400 pounds, plus 50 to 70 gallons of water at roughly 8.3 pounds per gallon, plus a bather, is a load of 900 to 1,200 pounds sitting in the middle of a floor span instead of against a bearing wall. Reinforcing the framing under it — sistering joists or adding blocking — runs $200 to $800 where an inspection shows it is needed, and is the reason a freestanding installation begins with someone looking underneath rather than with the tub.
Together these are why a freestanding tub installs at $3,500 to $8,000 against $1,500 to $3,000 for the alcove swap it replaces, even when the tub itself costs the same.
Tub-to-Shower Conversion — the Other Answer
A large share of people pricing a tub replacement are not attached to having a tub. They have a tub nobody uses, in the only bathroom, and stepping over a 15-inch wall every morning is the actual problem.
Based on aggregated data, a tub-to-shower conversion runs $3,000 to $10,000, with a typical project near $6,000 — materials $800 to $4,000, labor $2,000 to $5,500, across 3 to 7 days.
| Like-for-like tub swap | Tub-to-shower conversion | |
|---|---|---|
| Typical cost | $1,500–$3,000 | $3,000–$10,000 |
| Typical duration | 1–3 days | 3–7 days |
| Permit | Typically not required | Typically required |
| The floor | Tub sits on the subfloor | Becomes a waterproofed shower pan |
| The drain | Reused in place | Usually relocated to the pan outlet |
| Resale consideration | A home with no tub at all is a narrower sale | A second bathroom with a tub removes the objection |
The cost difference is concentrated in one place: the alcove floor. A tub is its own watertight vessel, so the floor under it is dry structure. A shower’s floor is the waterproofing, which means a mortar bed, a membrane, a bonded drain and tile — the whole assembly priced in shower pan installation at $500 to $3,500. That, plus the permit that usually attaches when the drainage changes, is the gap between a $2,500 swap and a $6,000 conversion. The bathroom remodeling hub prices the conversion alongside full remodels, and the calculator applies a city factor to either scope.
Refinishing vs Replacement
Reglazing is the cheap alternative, and it is a genuinely good answer to exactly one problem.
| Refinishing / reglazing | Replacement | |
|---|---|---|
| Cost | $350–$650 | $1,500–$8,000 |
| Duration | 4–6 hours, plus 24–48 hours cure | 1–3 days |
| Lifespan | 5–10 years | 15–70 years by material |
| Cost per year of service | ~$45–$100 | ~$70–$130 |
| Solves | Stains, dullness, surface scratches, dated color | Cracks, rust-through, leaks, wrong size, wrong type |
| Does not solve | Anything structural | — |
Refinishing strips and etches the existing surface, then sprays a new coating over it. That coating is a few thousandths of an inch thick, so it follows whatever is underneath: a hairline crack in the shell telegraphs through it, a soft spot stays soft, and a steel tub rusting from the back keeps rusting. Where the tub is sound and simply looks tired, $500 does what $2,500 would do. Where the tub is cracked, leaking, or the wrong tub, refinishing is $500 spent on the thing that has to come out anyway.
The cost-per-year row is the honest comparison, and it is closer than the sticker prices suggest. Two rounds of refinishing across 15 years costs about $700 to $1,300 and leaves a 20-year-old tub still in place; an acrylic replacement at $2,500 covers the same 15 years and has 10 or more left.
Cost by City
The tub, the drain assembly and the valve trim are national products — an acrylic alcove tub costs broadly the same in Houston as in Boston. Only the $500 to $3,500 labor line moves, following the formula City Adjusted Cost = National Average × City Labor Adjustment Factor.
| City | Labor Adjustment Factor | Adjusted Install Labor | Typical Project (tub + adjusted labor) | vs. National |
|---|---|---|---|---|
| Chicago, IL | 1.33 | $1,995 | $2,995 | +33% |
| New York, NY | 1.23 | $1,845 | $2,845 | +23% |
| Seattle, WA | 1.29 | $1,935 | $2,935 | +29% |
| Houston, TX | 0.93 | $1,395 | $2,395 | −7% |
| San Antonio, TX | 0.85 | $1,275 | $2,275 | −15% |
Labor adjustment factors are derived from BLS Occupational Employment and Wage Statistics (May 2025): the median ratio of local to national hourly wages across the trades that do this work. How this is calculated.
Chicago carries the highest labor adjustment factor in the dataset at 1.33 and San Antonio the lowest at 0.85 — about a $720 spread on a $1,500 mid-range labor line. That gap widens on a cast iron or tiled-surround job, where labor is most of the bill, and narrows almost to nothing on a $4,000 stone resin tub, where the fixture is. The calculator above applies any city’s factor to a specific tub and scope.
What Drives the Price
- Surround demolition and rebuild — $150 to $800 (panel) or $800 to $3,000 (tile). The largest swing factor on a like-for-like swap, and the one most often left out of a phone quote. The surround was built over the tub’s flange, so it comes off before the tub does.
- Tub material and weight — $200 to $4,000 for the unit. Fiberglass to cast iron is a $2,000 swing on the fixture and a $200 to $600 swing on the labor to carry and set it.
- Drain or valve relocation — $400 to $1,900. Triggered whenever the new tub’s drain is at the other end, the tub is a different length, or the old two-handle valve is replaced by a single-handle body that does not fit the existing hole. A shower valve replacement at $200 to $900 is the cheap version of this line, done while the wall is already open.
- Subfloor repair — $250 to $1,200. A tub that leaked at the drain or the flange has been wetting the sheathing under it for years. It is found when the tub comes out, never before, which is why it is carried as a contingency rather than a line. Severe cases are priced as subfloor replacement at $500 to $3,000 and, where the damage ran past the alcove, as water-damaged floor repair.
- Floor reinforcement — $200 to $800. Applies to cast iron, stone resin, and any large soaking tub set away from a bearing wall.
- Floor-mounted tub filler — $400 to $1,200. A freestanding-tub line item with no alcove equivalent.
- Dedicated electrical circuit — $300 to $1,000. Whirlpool, air-jet and walk-in tubs run a pump, which needs a GFCI-protected circuit and an access panel to reach the motor.
- Removal and disposal — $60 to $600. Cheap for a tub that can be cut up, expensive for 400 pounds of iron charged by weight at the tip.
- Permits — $0 to $500. A like-for-like replacement in the same location typically does not require one. Moving the drain, converting to a shower, or adding a circuit generally does.
DIY vs Professional Installation
A tub swap is one of the few bathroom jobs where the demolition half is genuinely DIY-able and the installation half is where the risk sits. The split below reflects that.
| Item | DIY cost |
|---|---|
| Acrylic alcove tub | $400–$1,500 |
| Drain and overflow assembly | $30–$90 |
| Tub-and-shower valve trim kit | $80–$300 |
| Three-piece surround kit | $200–$700 |
| Mortar bed under the tub (2–3 bags) | $20–$40 |
| Backer board and thinset for the wall | $60–$150 |
| Silicone, plumber’s putty, shims, screws | $30–$60 |
| Reciprocating saw blades, pry bar, level | $40–$120 |
| Dumpster bag or disposal fee | $60–$250 |
| DIY total (like-for-like acrylic swap) | $920–$3,210 |
| Same job installed | $1,500–$3,000 |
The arithmetic is unusual and worth reading twice: on a like-for-like acrylic swap, DIY and professional totals overlap almost completely. The reason is that the fixture and the surround kit are most of the money, and a homeowner buys them at retail while a contractor’s labor on a simple swap is only $500 to $900. Buying the tub at retail and paying a plumber to set it lands within a few hundred dollars of the all-in installed price.
Where the DIY number moves decisively is in the two directions the job usually goes. Downward: the demolition, the haul-out and the disposal are unskilled hours, and doing them before the plumber arrives removes $300 to $900 of labor from a quote. Upward: the drain connection under the tub is made once, from below or through an access panel, and is then permanently sealed behind a tub full of water. A weep at that joint is not discovered as a drip — it is discovered as a stain on the ceiling below, at which point the tub comes out again and the $250 to $1,200 subfloor line arrives with it.
Cast iron is the other line that decides itself. A 400-pound tub is not a solo lift, and the failure mode is not a cosmetic one.
Lifespan and Cost per Year
| Tub | Installed cost | Lifespan | Cost per year |
|---|---|---|---|
| Fiberglass | $1,500–$2,600 | 10–15 years | ~$100–$175 |
| Acrylic | $1,600–$3,400 | 15–30 years | ~$55–$115 |
| Porcelain-enameled steel | $1,700–$3,000 | 20–30 years | ~$55–$100 |
| Cast iron | $3,000–$5,500 | 40–70 years | ~$45–$80 |
| Stone resin | $4,000–$8,000 | 30–50 years | ~$110–$160 |
| Refinishing an existing tub | $350–$650 | 5–10 years | ~$45–$100 |
Cast iron is the cheapest per year of service in the set despite costing roughly twice what acrylic costs installed, for the same reason it is expensive to install: the material outlives the bathroom around it. Fiberglass sits at the opposite end — the cheapest tub to buy and the most expensive per year, because a gel coat that has gone dull and porous at year 12 is a replacement, not a cleaning problem.
Acrylic is where most of the market lands, and the cost-per-year table explains why: it costs a few hundred dollars more than fiberglass and lasts roughly twice as long.
Related Bathroom Costs
A tub replacement rarely stays a tub replacement, because the wall it sits against is open for the first time in twenty years. The valve behind it is the obvious companion job — a shower valve replacement at $200 to $900 is cheap while the surround is off and expensive once it is back on. Where the old surround is tile and the tile is sound, regrouting at $300 to $2,000 is the alternative to tearing it out.
If the tub becomes a shower, the alcove floor becomes a shower pan at $500 to $3,500 and the open side needs a shower door at $400 to $3,000 — the two lines that turn a $2,500 tub swap into a $6,000 conversion. The other fixtures in the room are priced separately: a bathroom sink runs $280 to $1,400 and a half bath remodel $1,500 to $12,000.
A walk-in tub is the accessibility alternative to a straight swap, and it is a materially different purchase: aggregated data puts it at $4,000 to $22,000 installed against $1,500 to $8,000 for a standard replacement, with almost the entire gap in the unit itself — $2,000 to $14,000 for a walk-in shell versus $400 to $4,000 for a standard tub. It is priced in full under walk-in tub cost.
Whether the room keeps a bathtub at all is a cost decision before it is a taste one, and the arithmetic inverts by tier: a prefab shower starts below a tub at $1,000 against $1,500, a mid-range tub undercuts a tiled shower at $2,500 against roughly $5,500, and at the top a shower has no ceiling while a tub does. The two are priced head to head in tub vs shower cost.
Where the tub is one line in a larger scope, the bathroom remodeling hub covers full remodels at $10,000 to $30,000 and shower remodels at $1,500 to $15,000. Tile on the surround or the floor is priced in the tile installation guide at $1,500 to $8,000, and the methodology page explains how every figure here is derived.
How to Reduce Bathtub Replacement Cost
- Match the new tub’s length, drain end and flange height to the old one before ordering. A 60-inch tub with a left-hand drain replacing a 60-inch tub with a left-hand drain is the entire difference between a $1,500 job and one carrying a $400 to $1,900 plumbing line.
- Price a panel surround against a tiled one on the same three walls. That single choice moves a swap by roughly $800 to $2,500 and changes nothing about the tub.
- Where the tub is sound and only looks tired, price refinishing at $350 to $650 against replacement at $1,500 to $8,000 before assuming replacement is the job.
- Take the demolition and the disposal on as homeowner work where that is practical — it is unskilled time, and it is $300 to $900 of a professional quote.
- Combine the tub, the valve and the door into one visit. Demolition, mobilization and the minimum call-out charge are billed once, not three times.
- Compare tubs on cost per year rather than on sticker price. Acrylic at $1,600 to $3,400 and fiberglass at $1,500 to $2,600 are a few hundred dollars apart on the invoice and roughly twice apart in service life.
Replacing the tub keeps the drain, the alcove and the waterproofing exactly where they are, which is why it lands at $1,500 to $8,000 while a tub-to-shower conversion runs $3,000 to $10,000 — the $600 to $1,600 drain relocation and the new pan are most of the difference.
Last updated: August 2026. All figures reflect aggregated national cost data and are not a quote for a specific bathroom. Actual pricing depends on tub type and material, surround construction, drain position, subfloor condition, and local market. See the methodology page for how figures are calculated and sourced.
