How to Tile a Three-Wall Shower
- 1). Measure across the width of one shower wall and mark the middle. Use a level and pencil to mark a vertical line from top to bottom at the middle.
- 2). Spread thinset mortar across the bottom half of the wall, using a notched trowel.
- 3). Set the bottom row of tiles into place in the thinset mortar, starting at the center line and working out in both directions to the sides. Set spacers between the tiles as you hang them. Put spacers below them as well, so there's a gap between the bottom row of tiles and the floor.
- 4). Cut the tiles at the ends as needed, using a tile saw.
- 5). Hang the next row up, again starting at the middle and working toward the sides. Continue up the wall, row by row, spreading more mortar as needed. Cut tiles around the fixtures as needed on your tile saw. Tile the whole wall, and the two adjacent walls. Let the mortar set overnight and remove the spacers.
- 6). Grout each shower wall from the top down, applying the grout with a grout float, pressing it into the spaces and squeezing it off the face. Don't fill in the spaces along the floor at the base of the walls, or in the vertical corners between the walls. Use a sponge to wipe off the residual grout. Let the grout set for 24 hours.
- 7). Run caulk lines along the floor and up the vertical corners, where you didn't grout, using a caulk gun. Let the caulk set for 24 hours.
