Tiling Shower Walls, Where To Start
- To start, remove the old tile or fiberglass shower wall. This job is dusty. Use plastic to cover your doorways, wear a respirator that’s rated for dust, cover the floor with a drop cloth, and make sure there’s plenty of ventilation. Tile is heavy, so put down blankets to protect the floors and tub from being damaged by falling pieces.
- Before you begin removing tile, turn off the power to the entire bathroom and any adjacent rooms. If you’re tiling a wall with outlets or wire fixtures, remove those before beginning demolition.
- Only cut the depth of the drywall to prevent cutting plumbing.
How To Retile A Shower
Here we describe the listed steps above.
Remove The Old Tile
- With your hammer and chisel, or crowbar, start removing the tile from the top to the bottom. Use a reciprocating saw to cut nails.
- If there is drywall remove that as well.
- Once the shower wall tile is removed, inspect the condition of the studs. Look for mold and only continue if there is no mold. If there is mold, call a pro to remove it.
Prep The Wall
- It is possible to not damage the backer board while removing the tile, but just plan on having to replace it because it’s very likely that you’ll damage it.
- Install backer board that is the same thickness of any remaining drywall. Any cuts for plumbing should be done outside since the cement board is dusty.
Layer Of Thinset Mortar
- When all of the board is installed use seam tape to tape the joints. Then coat over the tape with thinset mortar. Premixed is fastest and easiest.
- Apply two coats of water-proofing membrane paint over the entire surface you intend to tile, allowing the paint to dry between coats.
- Fill in any holes or gaps with silicone caulk.
- Hopefully the base of the show is even otherwise you’ll have to cut tile.
- Plan your pattern.
- Start the installation with the second row up from the bottom. Draw a line where the bottom of the second row is. Attach a board along the line with the top of the board located where the line is.
- Apply thinset mortar to the cement backer to install the shower wall tile.
- Firmly push the tile into place.
- Remove a single tile to see if the thinset is sticking to the entire tile.
- Remove the guide board and do the bottom row. Leave a ¼ inch expansion gap from the tile and the floor.
- Let thinset dry for 24 hours.
- Tile comes with a recommended grout that will work best with the tile. Use the recommended grout.
- Mix only a little grout.
- Apply the grout. Work the shower wall tile grout into the spaces using a diagonal motion. Use unsanded grout with glass, polished, or metal tile as these scratch easily.
- Wait for grout to dry – about 10 minutes. Wipe away excess with wet sponge without removing grout in the joints.
- Clean tile surfaces. Once grout is dry, clean the tile faces with a grout haze remover. Will likely have to do this multiple times.
- Apply grout sealer. After three days, apply a grout sealer to the grout, and apply a silicone sealant to the corners, edges, and joints.
Cost To Retile A Shower
Average is about $25 per square foot, so 6-8 feet of tile would be around $2000.
