Accidents happen, and sometimes, they leave us with a broken floor tile. Instead of living with an eyesore or risking further damage, learn how to replace a broken floor tile with this comprehensive, step-by-step guide. By the end, you'll have a flawless floor and a newfound DIY skill.
Gather Your Tools and Materials
Before you start, ensure you have all the necessary tools and materials. You'll need:
- Replacement tile (matching the size and design of the broken one)
- Tile nippers or wet saw (for cutting the tile, if needed)
- Trowel (notched and straight-edged)
- Grout float
- Grout (matching the color of your existing grout)
- Thinset mortar
- Safety glasses
- Gloves
- Kneepads (optional, but recommended for comfort)
Prepare the Work Area
Safety first! Clear the area around the broken tile, removing any furniture or debris. Lay down a drop cloth to protect the surrounding floor from any mess.

Remove the Broken Tile
Start by scoring the grout around the broken tile using a utility knife. This will help you remove the tile in one piece. Then, use a flathead screwdriver or pry bar to gently pry up the tile. If the tile is stubborn, you may need to use a hammer and chisel to break it into smaller pieces. Be careful not to damage the subfloor.
Clean the Area
Once the tile is removed, clean the area thoroughly. Use a wire brush to remove any remaining thinset or mortar, and vacuum or sweep away any debris. Ensure the subfloor is dry and in good condition before proceeding.
Cut the Replacement Tile (if needed)
If your replacement tile is larger than the space you need to fill, use tile nippers or a wet saw to cut it to size. Always wear safety glasses when cutting tiles.

Apply Thinset Mortar
Mix the thinset mortar according to the manufacturer's instructions. Using the notched trowel, spread a layer of mortar onto the subfloor, covering an area slightly larger than the tile. Then, use the straight-edged trowel to remove excess mortar and create grooves.
Install the Replacement Tile
Press the replacement tile firmly into the thinset mortar, using a twisting motion to ensure good contact. If necessary, use spacers to maintain consistent grout lines. Allow the mortar to set according to the manufacturer's instructions.
Apply Grout
Once the mortar has set, mix the grout according to the manufacturer's instructions. Using a rubber grout float, spread the grout over the tile and into the grout lines, at a 45-degree angle. Allow the grout to set for about 15-20 minutes, then use a damp sponge to wipe away excess grout. Let the grout cure according to the manufacturer's instructions.
Clean Up and Enjoy Your New Tile
Remove any remaining grout haze from the tile using a damp cloth or grout cleaner. Allow the tile to cure for 72 hours before exposing it to moisture or heavy foot traffic. Now, step back and admire your handiwork! You've successfully replaced a broken floor tile and saved yourself the cost of hiring a professional.
