How To Replace Broken Tile In Shower

Replacing a broken tile in your shower may seem like a daunting task, but with the right tools and a little patience, you can do it yourself. Here's a step-by-step guide to help you get the job done.

Tools You'll Need:

Chisel or utility knife
Hammer
Tile nippers or wet saw
Grout removal tool or oscillating multi-tool
Grinder (optional)
Adhesive trowel
Thinset mortar
Grout
Grout float
Sponges
Caulk gun
Waterproofing membrane (optional)

Step 1: Safety First

Before getting started, be sure to wear safety glasses and gloves. If possible, turn off the water supply to your shower to prevent any flooding. Cover the drain with a cloth or tape to keep small pieces of tile or grout from falling in.

Step 2: Remove the Broken Tile

Using a chisel or utility knife, carefully score around the perimeter of the broken tile. Place the chisel at a slight angle and tap it gently with a hammer to break the tile into smaller pieces. Once the tile is broken, use pliers to remove the pieces.

Step 3: Clean the Surface

Once the broken tile is removed, use a grout removal tool or oscillating multi-tool to remove any remaining grout or adhesive from the area. Vacuum the surface thoroughly to remove any dust or debris.

Step 4: Prepare the Replacement Tile

If necessary, cut the replacement tile to size using tile nippers or a wet saw. Be sure to wear safety glasses when cutting tiles. Place the replacement tile in the space where the broken tile was located to ensure it fits correctly.

Step 5: Apply Adhesive

Spread a thin layer of thinset mortar onto the back of the replacement tile using an adhesive trowel. Be sure to apply it evenly to prevent any air pockets from forming.

Step 6: Set the Tile

Carefully place the replacement tile in the desired location and press it firmly into the thinset mortar. Use a rubber mallet or a tapping block to gently tap the tile until it is level with the surrounding tiles.

Step 7: Grout the Tile

Once the tile is set, allow the thinset mortar to dry according to the manufacturer's instructions. Mix the grout according to the package directions and apply it to the joints between the tiles using a grout float. Press the grout firmly into the joints and wipe away any excess with a damp sponge.

Step 8: Seal the Grout

After the grout has dried, seal it to protect it from moisture and stains. Apply a thin layer of grout sealer to the joints and allow it to dry according to the manufacturer's instructions.

Step 9: Caulk the Edges

To prevent water from seeping behind the tiles, apply a thin bead of caulk along the edges where the tiles meet the wall or shower pan. Smooth the caulk with your finger or a caulk tool.

Step 10: Waterproof the Area (Optional)

If desired, apply a waterproof membrane to the area around the newly installed tile to prevent moisture from penetrating the substrate and causing damage. Follow the manufacturer's instructions for proper application.

Tips:

For heavily damaged areas, consider replacing multiple tiles or the entire shower pan.
If you're not comfortable replacing tiles yourself, don't hesitate to call a professional.
Take your time and be patient. Replacing tiles can be a time-consuming process, but it's important to do it right to ensure a long-lasting repair.
