How to Fix a Crack in My Shower Tile

Equip an electric or battery powered hand drill with a 1/4-inch drill bit and drill a hole in the corner of the cracked shower tile. Proceed to drill a series of holes in a line from this corner of the tile to the opposite corner. Space drill holes by 1 inch.

Split the tile along the line of holes using a chisel and hammer.

Remove the tile from the shower wall by prying it up with a flat bar.

Clean the space below the tile by scraping off the dried mortar with the chisel or flat bar.

Incorporate the mortar and water in a small bucket until is has the consistency of mayonnaise. Wait 10 minutes for it to mix properly.

Scoop the mortar onto the trowel and spread it into the vacant space with a thickness of 1/4 inch.

Make even sweeps with the notched side of the trowel over the mortar to texture it, then line up the replacement tile and firmly press it into the wet mortar.

Secure the tile in place by placing a wooden block on the the center of the tile and hammering gently with the heel of the hammer.

Wait for the mortar to dry overnight before continuing.

Incorporate powdered grout with water as directed, then wait 10 minutes for it to set.

Scoop the grout onto the tile and spread it into the joints with a rubber float. Allow the grout to dry partially so that a film appears on the tile surface, then sweep a damp cloth over the tile to remove this film.

Buff the tile with a dry cloth once the grout has cured for 2 to 3 hours. You can resume use of the shower after 24 hours.
