How to Demo Bathroom Tile and Surfaces
This is the dusty, loud, messy part of renovation—but also one of the most satisfying. Proper tile demolition sets the stage for everything that follows. Do it right, and you'll have a clean slate for new waterproofing and tile.
Quick Summary
Time needed
1-2 days (DIY)
Cost
$500-1,500 (pro) or DIY
Difficulty
Hard (physically demanding)
Safety First
Tile demolition sends sharp fragments flying. This is not optional safety gear—it's required.
- • Safety glasses or goggles (not just glasses)
- • N95 dust mask or respirator
- • Heavy work gloves
- • Long pants and long sleeves
- • Steel-toe or heavy work boots
- • Hearing protection (for power tools)
Tools for Tile Demo
Essential Tools
- Rotary hammer with chisel bit (rental: $40-60/day)
- Cold chisel and hammer (backup/detail work)
- Pry bar
- Reciprocating saw
- Flat shovel for scooping debris
Helpful Additions
- Shop vacuum (wet/dry)
- Heavy-duty buckets
- Floor scraper
- Oscillating multi-tool
Step-by-Step Demo Process
1. Prep the Space
Ensure water and electricity are off to the bathroom. Seal off the room with plastic sheeting to contain dust. Cover HVAC vents with tape and plastic. Have your dumpster or disposal ready.
2. Start with Wall Tile (Top to Bottom)
Begin at the top of walls and work down. Use the rotary hammer at a low angle to get under tiles. Let gravity work for you as tile falls away.
Technique:
- • Hold chisel at 30-45 degree angle to wall
- • Work along grout lines to break tile free
- • Don't force—let the tool do the work
- • Be extra careful around plumbing in walls
3. Remove Wall Backerboard
Once tile is off, remove the cement board or Hardie board underneath. Unscrew if possible, or pry off in sections. This exposes studs for inspection and new waterproofing.
4. Demo Floor Tile
Floor tile is typically harder than wall tile. Work from the edges inward. If tile was set in mortar bed, you may need to remove that too—it's heavy work.
5. Clean Up Continuously
Don't let debris pile up. Shovel into buckets regularly and haul to the dumpster. Tile is extremely heavy—don't overfill buckets or you won't be able to lift them.
6. Remove Thinset/Mortar Residue
After tile is gone, scrape remaining thinset from surfaces. A floor scraper or grinder works well. The surface doesn't need to be perfect—just remove high spots that would interfere with new installation.
Special Considerations
Asbestos Warning
Tiles installed before 1980 may contain asbestos, especially 9x9" floor tiles. If your home is older and you're unsure, have a sample tested before starting. Never disturb asbestos without professional remediation.
Lead Paint
If there's paint under tile or on walls in pre-1978 homes, it may contain lead. Take precautions when disturbing it—contain dust, wear proper respirator, clean up carefully.
Shower Pan Removal
If replacing the shower pan, demo it after wall tile is removed. Mortar shower pans are extremely heavy—break into sections. Pre-formed pans may lift out intact.
Frequently Asked Questions
How long does bathroom demo take?
A typical bathroom demo takes 1-2 days for DIY or 4-8 hours for professionals. This includes removing all tile, fixtures, and preparing for rough-in work.
Should I remove tile or go over it?
Always remove old tile in bathrooms. Installing over old tile adds height, hides potential water damage, and doesn't allow proper waterproofing.
Can I save the drywall behind tile?
In wet areas (shower, tub surround), you should remove drywall and replace with cement board. In dry areas, you may be able to save drywall if it's undamaged, but inspect carefully.
How do I dispose of tile debris?
Tile can go in regular construction dumpsters. It's heavy—a bathroom demo typically fills a 10-yard dumpster. Don't put in regular trash bins.
Ready for the Next Step?
With tile removed and surfaces exposed, it's time to inspect for hidden water damage and structural issues.
