Bathtub Replacement Cost: Average Prices & Cost Factors

Replacing a bathtub means pulling out the old tub, setting a new one, and reconnecting the drain and overflow. Surround walls, plumbing changes, and any damage found behind the old tub can add as much to the bill as the tub itself.

Prices on this page come from This Old House and one other published guide, last checked Oct 11, 2026. The tables break the job into the tub, removal, labor, and extras so you can see where the total comes from.

Material sets the price of the tub and also affects weight, heat retention, and how easy it is to install. Fiberglass and acrylic are light and sold in many stock sizes. Cast iron and solid surface are heavy, and the weight can raise the labor bill.

Fiberglass is the budget option and can feel thin underfoot. Acrylic is sturdier and holds heat longer. Cast iron is very durable and holds heat well, but it is hard to move and may need extra hands to carry. Solid surface is a premium material with a wide price spread, so the high end of the range goes to designer tubs.

The shape and style of the tub change the price more than almost any other choice. A standard alcove tub fits between three walls and is the least expensive to put in. Freestanding, jetted, and walk-in tubs cost more to buy and often need extra plumbing or framing.

• Standard (alcove). Fits the same footprint as most older tubs, so a swap usually leaves the plumbing where it is.
• Freestanding. Sits away from the walls and needs the drain and supply lines to reach it, which can mean opening the floor.
• Jet or whirlpool. Adds a pump and a power connection, usually on a dedicated circuit that an electrician should handle.
• Walk-in. Built with a door and a higher seat for easier entry. Some models include jets or other features, which is why the range is so wide.

• Tub size and weight. A larger or heavier tub takes more labor to carry in and set.
• Same footprint or new layout. Keeping the existing size and drain position is the cheapest route. Moving the drain or switching from alcove to freestanding adds plumbing work.
• Surround and wall finish. Tile, a one-piece surround, or a set of panels each carry their own cost and labor.
• Hidden damage. Soft subfloor, rot, or mold behind the old tub is common in older bathrooms and is rarely visible until demolition.
• Access. A second-floor bathroom, a narrow doorway, or a tight stairwell adds time.
• Local labor rates. Plumber and installer pricing varies from one metro area to the next.

Taking out the old tub is a separate line from installing the new one. Some contractors fold it into one quote and others itemize it, so ask which way your bid is written.

Cast iron tubs are the hardest to remove. Crews often have to break them into pieces on site. A fiberglass or acrylic tub is much lighter and usually comes out in one piece.

Two guides can look far apart for the same job because they describe different scopes. One may count only the tub and installer, while another includes demolition, a new surround, and plumbing work. A published average also reflects the mix of tubs in the sample.

When you compare a contractor's quote with these numbers, line up the scope first. A quote that includes a new surround and a new faucet is not comparable to a tub-only price.

If the tub is structurally sound and the problem is a worn, stained, or chipped finish, refinishing can be an option. It restores the surface without removing the tub or touching the plumbing.

Refinishing does not fix cracks that leak, a tub that is the wrong size, or a layout you want to change. If you are already planning to redo the walls or move the plumbing, replacement usually makes more sense than a surface repair. A bath liner, which fits over the existing tub, is another route; a contractor can tell you whether yours is a good candidate.

Swapping an alcove tub is within reach for an experienced DIYer, but it is heavy and unforgiving work. A misaligned drain or a poor seal can leak into the floor below for months before anyone notices. Jetted tubs add electrical work, and many areas require a permit and a licensed plumber or electrician for that. If you hire out the job, ask whether the labor carries a warranty, and check that the installer is licensed in your state.

• Does the price include removal and disposal of the old tub?
• Is the surround, faucet, and drain hardware part of the bid or a separate purchase?
• What happens if rot or water damage turns up behind the old tub?
• Who pulls the permit, if one is needed?
• What is the warranty on the tub and on the labor?
