Measure the right quantity
Measure bathroom floor area and identify fixture locations, the wet-area scope, and any layout changes. Floor area is not the same as the amount of wall tile to install.

How this estimate is calculated
Total range = bathroom square feet × adjusted remodel cost per sq ft, with scope, wet-area work, plumbing changes, and region included.
The calculator treats shower and waterproofing complexity as a major modifier because hidden damage and tile labor can swing the final quote.
Disclaimer: This is a budgeting estimate only, not a contractor quote, inspection, engineering opinion, code review, legal advice, insurance advice, tax advice, or safety recommendation. Actual costs vary by local labor rates, material availability, contractor schedule, permit requirements, site conditions, and scope changes.
How do I build a bathroom remodel budget before requesting bids?
Combine bathroom size with the remodel scope, shower or tub work, tile level, and plumbing changes. A small room can still require several trades and substantial waterproofing. Treat hidden water damage and structural repairs as inspection-dependent work.
Compare the same written scope
Match fixtures, tile, waterproofing, demolition, plumbing relocation, ventilation, permits, and finish work. Ask whether material allowances include both purchase and installation.

Walk-In Shower Cost CalculatorHow to use this bathroom remodel calculator
Use it for a planning range
- Enter the bathroom floor area and choose the remodel scope that best matches the planned work.
- Select shower or tub scope, tile level, plumbing changes, and broad US region.
- Use the range to compare whether contractor bids include waterproofing, fixture allowances, tile labor, demolition, disposal, and permits.
Example bathroom remodel estimate
- 70 sq ft bathroom
- Standard remodel with a replacement tub or shower kit
- Midrange tile, same fixture locations, and US national baseline
The calculator estimates cost from bathroom area, then adjusts for scope, wet-area work, tile level, plumbing movement, and region.
A higher quote may be reasonable if it includes custom tile, waterproofing upgrades, subfloor repair, ventilation work, or fixture relocation.
Common cost drivers
- Custom tile showers and waterproofing details can raise labor and risk.
- Moving toilets, showers, tubs, or vanities adds plumbing work and may trigger permit review.
- Hidden subfloor damage, mold, old plumbing, or poor ventilation often changes the final scope.
- Fixture allowances and finish selections can make two similar bathroom quotes look very different.
Use this range to compare local quotes
Before comparing prices, make sure each written quote uses the same bathroom size, wet-area scope, waterproofing, fixture allowances, tile work, trade work, repair, permit, warranty, and payment assumptions.
Cosmetic bathroom refresh
Same layout, limited tile, basic vanity or fixtures, and no wet-area rebuild.
Standard bathroom remodel
Tub or shower replacement, midrange tile, fixture allowances, demo, disposal, and normal trade work.
Gut remodel or custom wet area
Custom tile shower, waterproofing system, fixture relocation, subfloor repair, ventilation, or permit-heavy work.

Bathroom remodel cost calculator FAQ
Does this bathroom remodel calculator include tile work?
Yes, it includes a broad tile-level modifier. It does not replace a tile contractor's layout, waterproofing, substrate, or material-specific quote.
Does the estimate include hidden water damage?
No. Subfloor repair, mold remediation, concealed plumbing damage, and structural issues are excluded because they usually require inspection or demolition to confirm.
When should I call a licensed pro for a bathroom remodel?
Call licensed professionals for plumbing relocation, electrical changes, waterproofing, ventilation changes, mold, accessibility work, or any permit-triggering scope.
Why can a small bathroom still be expensive?
Bathrooms pack plumbing, electrical, waterproofing, tile, fixtures, ventilation, and finish labor into a small area, so cost per square foot is often higher than in larger rooms.
