Bathtub Replacement Cost in 2026: What to Expect

A basic alcove acrylic tub costs $400-$900 for the fixture alone. A cast iron soaking tub runs $1,000-$3,000. A freestanding tub - the kind that sits away from the wall - can reach $2,000-$8,000 before installation. The fixture cost drives the project budget more than any other single factor.

A straight tub swap with no tile work keeps costs low - maybe $1,000-$1,500 total. Adding a new tile surround from scratch runs $800-$2,500 in materials and labor. Full floor-to-ceiling tile on all three alcove walls can add $2,000-$4,000 to the project.

Replacing a tub in the same location is straightforward - the drain and supply lines don't move. Moving the drain even a few feet requires cutting into the subfloor, which adds $1,000-$2,500 in plumbing labor. Moving to a completely different wall can push that to $3,000-$4,000.

Standard 60-inch alcove tubs are the simplest swap. Upgrading to a 66- or 72-inch soaking tub or a wider drop-in tub usually requires modifying the surrounding framing or deck, adding $200-$1,500 in carpentry labor on top of the fixture upgrade.

“Will you need to modify the drain or supply lines, and is that included in your quote?”

Why this matters: Many tub replacement quotes assume a direct swap. Any plumbing modification - even adjusting the overflow height - can add $300-$1,500. Get clarity upfront so you're not hit with a change order.

“What waterproofing system do you use behind the tile surround?”

Why this matters: The area behind a tub surround is the most failure-prone spot in any bathroom. Ask whether they use Schluter Kerdi, RedGard, or a similar membrane system - not just cement backer board alone.

“Do you haul away the old tub, and is that included in the price?”

Why this matters: Old cast iron tubs weigh 300-500 lbs and can't go in a regular trash bin. Disposal fees can add $100-$400. Know whether it's included before you sign.

“Is a permit required for this replacement, and do you handle it?”

Why this matters: A like-for-like tub swap usually doesn't need a permit, but any plumbing modifications may. Unpermitted plumbing work can surface during a home sale inspection and require costly corrections.

“Can you show me examples of freestanding tub installations you've done?”

Why this matters: Freestanding tubs have a floor-mounted filler and no built-in overflow - the installation is different from an alcove tub. If you're going freestanding, make sure the contractor has done it before.
