The Bathroom Demolition Cost Calculator estimates the cost of gutting a bathroom before a remodel. It prices floor removal and wall tile or drywall removal per square foot, removal of each fixture (toilet, vanity, tub), and debris haul-away or a dumpster.
Bathroom Demolition Cost Calculator
Estimate the cost of gutting a bathroom — tile and drywall removal, fixture removal and debris haul-away.
Rates are examples — enter quotes from local contractors. If your home is older, have suspect materials (flooring, adhesives, plaster) tested for asbestos before demolition.
Formula
Cost = L × W × floor rate + wall area × wall rate + fixtures × cost per fixture + haul-away
How the Calculation Works
Step 1: Floor area × floor removal rate.
Step 2: Wall tile or drywall area × wall removal rate.
Step 3: Add fixture removals and disposal.
Variables Explained
| Input | Meaning |
|---|---|
| Wall tile / drywall to remove | Area of wall finishes being stripped |
| Floor / wall removal | Rates per ft² |
| Fixtures to remove | Toilet, vanity, tub, shower, etc. |
| Haul-away / dumpster | Disposal cost as a lump sum |
Example Calculation
Given (example prices): 8 × 5 ft bathroom, 80 ft² of wall tile, floor $4/ft², walls $3/ft², 3 fixtures at $125, $400 haul-away
- Floor = 40 × 4 = $160
- Walls = 80 × 3 = $240
- Fixtures = 3 × 125 = $375
- Total = 160 + 240 + 375 + 400 = $1,175
What Affects Demolition Cost
- Tile set in a mortar bed is harder to remove than tile on backer board.
- Cast-iron tubs are heavy and may need to be broken up.
- Access: upper floors and tight stairways add time.
- Hazardous materials testing and abatement are separate and regulated.
- Local disposal fees.

Can I demolish a bathroom myself?
Many homeowners do, but shut off water and power, protect nearby rooms, and test for asbestos in older homes first.
What does bathroom demolition include?
Removing fixtures, tile, flooring and, for a full gut, drywall down to the studs, plus hauling debris.
