About BathCalc
Free bathroom cost calculators · No sign-up · No sales calls
BathCalc exists because pricing a bathroom project in the U.S. is needlessly opaque. Contractor sites ask for your phone number before showing a number; blog posts give a single national average that doesn't match your room. We do the opposite: an instant, adjustable price range, no email required.
How our calculators work
Each calculator runs a transparent pricing model: a fixed setup cost plus a per-unit rate (per square foot or per fixture), adjusted by U.S. region, with a low-bid-to-high-bid span (−15% / +18%). All math runs in your browser — nothing you enter is transmitted or stored.
Where the numbers come from
BathCalc uses editable planning assumptions, not a survey of contractor bids. Each calculator’s methodology lists its formula, base rates, option allowances and regional factors. Reference links help compare project scopes; they do not certify BathCalc’s rates or imply endorsement.
The 85%–118% range is a model allowance, not a statistical confidence interval. Regional factors are broad assumptions rather than ZIP-code estimates. Get itemized local quotes and compare inclusions before committing to a project.

What we are not
- Not a lead-gen service. We never sell your contact information — we don't collect any.
- Not a contractor. Estimates are planning ranges, not quotes. Always get two or three local bids.
- Not affiliated with any brand. BathCalc is independent; product names mentioned (including Jacuzzi®) are trademarks of their owners.
