Removal

• 1). Cover the floor beneath the ceramic wall tile. Use a disposable drop cloth, so that you can just pick up the entire thing and throw it away after removing the older ceramic tile.
  
  
• 2). Remove the caulking from around the edges of the tile and around the fixtures. Cut into the caulk with a utility knife, wedge a flathead screwdriver into the cut and pry the caulk up slowly to remove as much as possible.
  
  
• 3). Break the older ceramic wall tiles if you don't plan to use them again. Put on protective goggles and hit each tile squarely in the middle with a hammer hard enough to break it. Pry up the pieces that do not automatically fall from the wall with the flathead screwdriver.
  
  
• 4). Go over the wall's surface with a paint scraper that has a carbide blade to loosen the tile adhesive. Brush the wall off with a cleaning brush to remove the debris.
  
  

Replacement

• 1). Find the midpoint on the wall on which you will be replacing the tile. Measure the height of the wall space with a metal ruler and mark the midpoint with a pencil and then measure of width of the space and mark the midpoint. Lay the ruler vertically on the wall so that it lines up with the midpoint of the wall's width and draw a straight line down the wall, and then lay the ruler horizontally so that it lines up with the midpoint of the wall's height and draw a straight line across the wall. You thus divide the space into four equal sections.
  
  
• 2). Rub the entire wall area with coarse sandpaper until the surface feels rough. Remove any dust on the wall with a wet rag.
  
  
• 3). Lay the first tile. Spread adhesive in the center of the wall in the corner of one of the sections you created. Place the first tile so that it lines up with both the vertical and horizontal line.
  
  
• 4). Place a tile spacer along the first tile and lay the second tile right next to the first so that it lines up with either the horizontal or vertical line. Continue to add tiles in this manner, so that the tiles are lined up and evenly spaced.
  
  
• 5). Remove the tile spacers and let the adhesive dry on the wall for 24 hours. Fill in the spaces between the tiles with grout by spreading the grout over the tiled surface with a grout float. Press the grout down in between the tiles and remove any grout from the tiles surface with a wet rag. Let the grout dry for 24 to 48 hours before touching the wall.
