Independent cost estimates for major home projects
U.S. BATHROOM REMODELING / COST BY SIZE
A flat cost-per-square-foot rate can be misleading. Compare published U.S. ranges, then see how our model behaves when the same fixtures are priced in differently sized rooms.
Quick answer: HomeGuide's published U.S. guide estimates roughly $100–$500 per sq ft across different remodel types. A cosmetic refresh and a full renovation cannot be priced at the same rate. Scope, fixtures, finishes and location matter just as much as floor area. See costs by scope.
01 / SAME PROJECT, FOUR ROOM SIZES
We ran our standard Texas bathroom project through the calculator at four floor areas. Every other input stays fixed: one tiled walk-in shower, a single vanity, replacement toilet, tile floor, 15 sq ft of wall tile, paint, one or two electrical points, an exhaust fan, professional installation and a general contractor. Same layout, standard finishes and no known hidden issues.
In this controlled model test, only floor-tiling quantity changes with room size; the shower, vanity, selected wall-tile area, painting, demolition and other allowances remain fixed. The result illustrates fixed-cost effects, not how actual differently sized bathroom quotes necessarily scale.
02 / THE NUMBERS
All totals below are generated by EstimateAhead cost model v1.0 (last updated October 11, 2026), using its Texas regional adjustment. The last column divides the displayed, rounded likely total by room size, then rounds to the nearest dollar.
| Room size | Low total | Likely total | High total | Likely / sq ft |
|---|---|---|---|---|
| 35 sq ft | $13,800 | $19,300 | $26,300 | $551 |
| 50 sq ft | $14,000 | $19,600 | $26,800 | $392 |
| 80 sq ft | $14,500 | $20,300 | $27,700 | $254 |
| 120 sq ft | $15,100 | $21,200 | $29,000 | $177 |
This is a controlled illustration, not a claim that a typical 120 sq ft primary bathroom has the same fixtures as a 35 sq ft full bath. Different room types and more elaborate layouts require different inputs.
03 / PUBLISHED PRICE RANGES
HomeGuide's published U.S. cost-per-square-foot ranges vary with how much work is included. They are broad guide figures, not direct quotes or measurements of EstimateAhead's Texas scenarios.
Flooring, vanity, paint and fixture updates.
Selected major replacements, such as a shower or vanity.
Extensive work, potentially with custom finishes or layout changes.

04 / THE IMPORTANT DISTINCTION
Floor area helps estimate material quantities, but it doesn't reliably tell you how many fixtures need installing or how much plumbing work is involved.
Flooring installation and floor tile quantities increase as the room grows. Extensive wall tiling and paint can also rise, but wall surface and floor area are not the same measurement.
A shower, toilet, vanity and exhaust fan each need their own materials and installation. A 35 sq ft bathroom may still require most of the same fixtures as an 80 sq ft bathroom.
Moving pipes, electrical upgrades, demolition, hidden damage, permits and project management depend on the work being done—not simply on the dimensions of the room.
05 / INDEPENDENT CONTEXT
These sources describe different project samples and methods. Their figures should not be averaged with EstimateAhead's modeled examples, or treated as a validation of every component in our model.
COST PER SQUARE FOOT · 2025 GUIDE
Publishes an overall U.S. range of $100–$500 per sq ft. It separates minor, partial and full renovations, with different per-foot ranges for each. Published June 20, 2025.
WHOLE-PROJECT DATA · OCTOBER 2026
Reports a $12,156 national average and $6,651–$17,662 typical range, based on 28,374 verified Angi Pro projects. This is whole-project evidence—not a directly comparable per-foot price. Updated October 27, 2026.
COST BY ROOM SIZE · JULY 2026
Provides room-size and scope breakdowns, drawing on Homewyse estimates and a separate survey of 1,000 U.S. homeowners. Its examples use different fixture mixes and scopes from our standardized Texas scenario. Updated July 2, 2026.
06 / COMMON QUESTIONS
No. The published rate depends on scope, materials, local labor and what the contractor includes. Ask for a written scope and itemized allowances rather than treating a rate as a guaranteed price.
Not always. Our size comparison deliberately holds the same shower, vanity and trades constant. A powder room without a shower can be substantially cheaper than a tiny full bathroom. In real projects, larger rooms often require extra wall preparation, tile, fixtures or labor that our fixed-selection exercise intentionally does not add.
Start with room size, then specify the shower or tub, vanity, tile, electrical and plumbing work, finish level and state. Our bathroom calculator prices these selections individually. Its bathroom size input directly changes floor coverage; for additional painting, wall tile or extensive demolition, review the scope and selected surface area with a local contractor.
07 / PLAN YOUR BATHROOM
Enter your state, bathroom size, shower or tub, finishes and trade work to get a project-specific planning range. Compare item descriptions carefully: national installed-price guides can bundle removal or hookups, and our model has not been validated against matched itemized contractor quotes in every location.
