How Much Does It Cost to Replace a Bathtub?

Bathtub replacement costs $1,400–$5,800 including removal of the old tub, new tub purchase, plumbing hookup, and wall repair. The tub itself is only 30–40% of the total cost—labor, plumbing, and wall finishing account for the rest.

Material drives the biggest cost difference. Acrylic tubs ($200–$800) are the most common replacement choice—lightweight, easy to install, and durable. Fiberglass ($150–$500) is cheaper but scratches easily and yellows over time. Cast iron ($400–$2,000) lasts 50+ years but weighs 300–400 lbs, requiring floor reinforcement in many homes.

The hidden cost is what’s behind the walls. About 25% of bathtub replacements uncover water damage, mold, or outdated plumbing that adds $500–$3,000 to the project. Budget a 15% contingency.

Frequently Asked

Common questions.

How much does it cost to replace a bathtub?
Replacing a bathtub costs $1,400–$5,800 total. That includes removal ($200–$500), new tub ($150–$2,000), plumbing ($300–$800), and wall surround repair ($400–$1,200). Acrylic tubs are the most cost-effective choice for most homeowners.
How much does bathtub installation cost?
Bathtub installation labor costs $500–$1,800 depending on complexity. A simple swap (same size, same location) runs $500–$800. If plumbing needs to be moved or the subfloor requires repair, labor jumps to $1,200–$1,800.
How much does a walk-in bathtub cost?
Walk-in bathtubs cost $3,000–$9,000 installed. The tub itself runs $2,000–$5,000. Installation adds $1,000–$4,000 because walk-in tubs require wider door openings, reinforced flooring, and dedicated plumbing connections. Kohler and American Standard are the most common brands.
Should I replace or refinish my bathtub?
Refinish ($300–$600) if: the tub is structurally sound, you want to keep the same layout, or you’re selling within 10 years. Replace ($1,400–$5,800) if: there’s rust-through, persistent leaks, cracks in the tub body, or you want to change the tub style/size.
How long does it take to replace a bathtub?
A straightforward bathtub replacement takes 1–2 days. If the subfloor needs repair or plumbing needs to be moved, add 1–3 days. Wall surround replacement (tile) adds another 2–4 days for setting and grouting.
