Introduction
The drawings here show how to replace a single ceramic tile. If you have a leak behind a tile wall, you'll have to remove all the affected tiles and replace the wall behind the tiles. Adapt the same technique to larger areas, but apply adhesive to the wall, not the tiles.
When replacing a section of tiles, plan the opening so it straddles two studs. Then it is easier to patch the wall behind the tiles. Use water-resistant drywall or cement backerboard for your wall patch. Don't bother salvaging old tiles; most will break anyway. |

1. Remove bad tiles
Isolate the bad tiles by chipping away the grout around them with a grout scraper or chisel. Smash them one at a time, knocking out the pieces. |

2. Replace adhesive
Scrape all old adhesive from the wall. Spread the back of each new tile with a thin, even coat of tile adhesive. |

3. Put new tile in place
Press the tile into place, adjusting the grout spacing, then tap in place with a wood block and hammer. |

4. Grout spaces
Wipe excess adhesive from the surface. Clean out the grout spaces and regrout. |
