How to Install a Shower Tile Wall

Give your bathroom a fresh look by tiling the shower walls. We can help with step-by-step instructions including how to apply grout between your tiles and a list of materials and tools you'll need to get a professional-looking result.

Check Temperature

Ensure temperature of the room, adhesive and tiling materials are between 50 to 70 degrees F for 24 hours before and after installation.

Clean Surface

Be sure your surface is flat, dry and structurally sound. Clean walls with mild soap and a sponge before installation.

Waterproof Area

Attach a waterproof board (a GreenBoard or cement board) with a drill and screws. Apply fiber tape to cover all seams. For more protection, apply a waterproof sealer to the concrete backer board (Images 1 and 2).

Prep for First Row

For your first row of tile, use a long board (just shorter than the length of the wall you are tiling) as a temporary guide and rest. Ensure the board is level, within one tile height of the wall base.

Prep Mortar

Prep mortar in a large bucket, and combine thinset mortar and water according to package instructions. Only mix what you can use in 20 minutes time.

Apply Mortar

Apply thinset mortar mix to the waterproof board along the temporary guide board using a notched trowel. Only apply two to three horizontal rows at a time.

Install Tile

Before applying your tile to the wall, decide on the layout and orientation of your tile by positioning the tiles on the floor. Install full-piece tiles first, and fill in with cut pieces as you go or install them at the end. If you wait to install the cut pieces, use a notched trowel to scrape the thinset from the wall so it doesn't dry before installation. When installing cut pieces, apply the thinset to the back of each tile.

Evenly Space Tiles

Continue installing tile in horizontal rows, placing spacers of choice in between tiles. Once the thinset dries (at least 12 hours), remove the temporary wood board, and install tile on the bottom row. Let dry for 24 hours, and remove spacers.

Apply Grout

Mix grout in a large bucket according to package instructions. Apply grout with a rubber float at a 45-degree angle. Use pressure to push the grout evenly and fully into all joints.

Wipe Away Excess

Before grout stiffens, use a wet sponge to wipe away excess grout off tiles. Don't wipe in the direction of the grout lines, but instead at an angle to avoid wiping away the grout between the tiles. Once dry, buff tile surface with a dry towel.
