How This Calculator Works
This bathtub replacement cost calculator estimates your total project cost from four inputs: project size, quality tier, the options you select, and your location. It combines material and labor rates for your chosen tier, adds typical permit costs, then applies a regional cost multiplier so the estimate reflects pricing in your state.
Estimates use 2026 cost data cross-referenced from multiple industry sources. Treat the result as a planning range, not a quote. Your final price depends on your specific scope, material choices, and local contractor availability, so collect at least three itemized bids before you set a budget.
What Affects Your Bathtub Replacement Cost
Tub Type
$500 - $8,000A 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.
Tile Surround Work
$800 - $4,000A 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.
Plumbing Relocation
$1,000 - $4,000Replacing 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.
Tub Size
$200 - $1,500Standard 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.
