How to use the bathroom remodel cost calculator
- Measure the bathroom floor and pick a scope: a minor refresh (fixtures and finishes in place), a partial remodel, or a full gut.
- Leave a contingency if you want a cushion. Ten percent is a common starting point; HomeGuide also mentions a general-contractor share of 10–20%.
- Price a vanity or a countertop on their own pages when you want a single line, not a whole-bath total: the bathroom vanity cost calculator and the countertop cost calculator. A kitchen is on the kitchen remodel cost calculator.
HomeGuide scope bands, and the project-total guides
HomeGuide (article dated June 20, 2025) prices a bathroom remodel at $100–$150 per sq ft for a minor refresh, $150–$300 for a partial remodel and $250–$500 for a full remodel. Those midpoints — $125, $225 and $375 — are the typicals this calculator multiplies by your area. Angi (October 27, 2026) publishes a national average of $12,154, a typical project range of $6,651–$17,660, and an overall $70–$250 per sq ft that mixes scopes. The Houzz 2026 U.S. Bathroom Trends Study (2025 spend, 1,619 respondents) reports a $15,000 median. NerdWallet (2026) puts a typical job at $6,600–$18,000.
A 40 sq ft partial remodel is 40 × $225 = $9,000 typical, with a HomeGuide spread of $6,000–$12,000, before contingency. That sits a little below the $12,000–$15,000 project-average cluster, which is what you would expect if those averages mix in full remodels and larger primary baths. Angi and HomeGuide disagree on per-square-foot bands ($70–$250 vs $100–$500); both are shown, and the estimate follows HomeGuide’s scope table because Angi does not publish a matching minor/partial/full $/sq ft split.
A worked example: 40 sq ft partial remodel
A 5 × 8 ft guest bath is 40 sq ft. A partial remodel at HomeGuide’s $225 typical is $9,000, in a $6,000–$12,000 band. A 10% contingency brings the typical to $9,900. A vanity-only swap, or a quartz top by the square foot, should be checked on the dedicated vanity and countertop pages rather than inferred from this whole-bath total.
Sources & assumptions
How this calculator gets its numbers. Full method: our methodology.
- The per-sq-ft engine is HomeGuide’s scope bands: minor $100–$150 (typical $125), partial $150–$300 (typical $225), full $250–$500 (typical $375).
- Angi ($12,154 average; $6,651–$17,660 typical; $70–$250 per sq ft overall), Houzz 2026 median $15,000, and NerdWallet $6,600–$18,000 are shown as project context and are not multiplied by the bathroom’s area.
- Angi and HomeGuide disagree on per-sq-ft bands; both are on the page, and the estimate follows HomeGuide because Angi does not publish a matching minor/partial/full $/sq ft split.

Frequently asked questions
How much does a 40 sq ft bathroom remodel cost?
A partial remodel typically costs $9,000 before contingency, from HomeGuide’s $150–$300 per sq ft band. The spread on that size is $6,000–$12,000. A 10% contingency brings the typical to $9,900.
Why is Angi lower per square foot than HomeGuide?
Angi’s overall $70–$250 per sq ft mixes scopes and sits below HomeGuide’s full-remodel $250–$500 band. The calculator follows HomeGuide’s scope table and shows Angi, Houzz and NerdWallet project typicals as context rather than blending the units.
What is the difference between minor, partial and full?
HomeGuide’s minor band ($100–$150 per sq ft) is a refresh with the layout left alone. Partial ($150–$300) replaces some fixtures and finishes. Full ($250–$500) is a gut, often with plumbing or layout changes.
Does this include a new vanity?
A whole-bath total assumed in the guides usually includes a vanity line, but a stand-alone vanity or countertop should be priced on the vanity and countertop calculators if that is all you are doing.
