Bathroom Remodel Cost Calculator: Estimate Your 2026 Price by ZIP
A calculator is only as good as its assumptions. Here's the exact formula behind our bathroom estimator — and how to adjust it for your house.
Most online bathroom calculators spit out one number and hope you don't ask questions. Ours shows the math, because a $14,000 estimate means nothing until you know what tile grade and labor rate produced it.

Open the Bathroom Remodel Cost CalculatorThe Formula We Use
Base cost per square foot × bathroom size × scope multiplier × regional ZIP multiplier, plus fixed fixture costs. For 2026 the base rates are:
- Cosmetic refresh: $110–$180 per sq ft of floor area
- Mid-range remodel (new tile, tub/shower, vanity): $280–$420 per sq ft
- Full gut with plumbing relocation: $450–$700 per sq ft
What You'll Need Before You Start
- Floor area in square feet — length × width, measured to the walls.
- Whether the tub, toilet or shower drain is moving.
- Your finish tier: builder, mid-range or premium.
- Your ZIP code, which sets the labor index.
- Whether you're hiring a GC or coordinating trades yourself.
Reading Your Result
The calculator returns a range, not a point. Treat the low end as your best-case with a lean contractor and in-stock materials, and the high end as what you'll pay if the walls open up and reveal 1970s plumbing. Budget to the midpoint and hold 12% back.
Why Estimates Differ From Real Bids
- Access — a second-floor bath with a narrow stair adds labor hours.
- Demo condition — plaster and lath costs more to remove than drywall.
- Schedule — peak season (spring and early summer) bids run 5–10% higher.
- Tile format — large-format and mosaic both slow setters down versus 12×24.

Bathroom Remodel Labor Cost CalculatorFAQ
How accurate is a bathroom remodel cost calculator?
A well-built calculator lands within about 15% of real contractor bids when you input accurate square footage and scope. It can't see hidden rot, outdated wiring or code upgrades behind your walls.
Should I use the low or high end of the estimate?
Plan your budget around the midpoint and keep a 10–15% contingency. Use the low end only if you already have bids in hand and know the wall cavities are sound.
Is the calculator free?
Yes — no signup, no email, and nothing is sent to contractors. It runs entirely in your browser.
