Bathroom Remodel Cost Calculator
Create a low, typical, and high bathroom remodel budget with a category-by-category breakdown.
What this calculator includes
Choose the room size and scope instead of relying on one national cost-per-square-foot number. The calculator builds low, typical, and high planning ranges for general finish work, flooring, tile, shower or tub, vanity, fixtures, layout changes, permits, and contingency. The built-in installed-cost allowances are broad illustrative assumptions; an editable local adjustment is included, but measured quantities and written quotes should replace every allowance.
How to use this bathroom remodel cost calculator
- 01
Define the room and finish level
Use finished floor area and select the quality tier that best matches the fixtures and finish expectations.
- 02
Choose the real scope
Identify layout changes, shower or tub work, vanity type, flooring, wall tile area, and fixture count.
- 03
Adjust for market and risk
Select a broad installed-cost market, refine it with the editable local adjustment, enter known permit allowances, and choose a contingency appropriate for uncertainty.
- 04
Replace assumptions with quotes
Use the category breakdown to collect comparable contractor and supplier quotes rather than treating the range as a bid.
Worked example
Example: 60 sq ft standard bathroom
A 60 sq ft standard-scope room with the average installed-cost factor, ceramic flooring, 80 sq ft of wall tile, a replacement tub, semi-custom vanity, four fixtures, no layout change, a $500 permit allowance, and 15% contingency gives a $19,504 typical planning amount, with a low-to-high category range shown alongside it.
Practical buying and overage guidance
Complete a written scope and finish schedule before comparing proposals. Separate allowances from fixed selections, confirm who buys each item, and identify demolition, disposal, waterproofing, electrical, plumbing, ventilation, permits, protection, cleanup, and concealed-condition terms.

Frequently asked questions
How much does a bathroom remodel cost per square foot?
There is no dependable universal rate. Size, tile area, plumbing relocation, waterproofing, fixtures, access, labor market, permits, and concealed conditions can move the result substantially. The calculator shows its rough cost per square foot only as a summary of the selected scope.
Why is the estimate a range?
Early projects contain unresolved product, labor, and hidden-condition choices. Low, typical, and high values communicate that uncertainty more honestly than one precise-looking number.
How much contingency should I carry?
Ten to twenty percent is a common planning range, with more uncertainty in older rooms, layout changes, water damage, or projects without completed drawings and selections. Contingency is not a substitute for investigation.
Does moving plumbing cost more?
Usually. Layout changes can involve demolition, framing, supply and drain relocation, electrical work, patching, inspections, and schedule coordination. The toggle adds a broad allowance, not a site-specific quote.
Are permits included?
Only the permit amount you enter is included. Required permits, plan review, inspections, design fees, and licensed trades vary by jurisdiction and scope.
Does this include hazardous materials or water damage?
No. Lead, asbestos, mold, rot, structural repairs, and other concealed conditions need qualified assessment and separate scope.
