How to Retile a Bathroom Shower

Retiling a shower involves removing old tiles, preparing the surface, installing new tiles with proper adhesive, and sealing with grout and caulk.

  1. Strip and Clean to the Wall. Start by removing all old tiles using a hammer and chisel or oscillating multi-tool. Work carefully to avoid damaging the wall structure. Scrape off any remaining adhesive and clean the surface thoroughly. Check for water damage or mold and address these issues before proceeding. The wall should be completely smooth and dry before tiling.
  2. Waterproof Before You Tile. If your walls aren't already waterproofed with cement backer board or similar material, install it now. Cut the board to fit using a utility knife and secure with appropriate screws. Seal all joints with mesh tape and adhesive. This step is crucial for preventing water damage behind your new tiles.
  3. Measure Twice, Cut Once. Measure the shower walls and plan where each tile will go. Start from the center of the most visible wall and work outward to ensure even spacing. Use a level to mark horizontal and vertical reference lines. This planning prevents awkward partial tiles in prominent areas and ensures your pattern looks intentional.
  4. Set Tiles True and Straight. Mix your tile adhesive according to manufacturer instructions. Apply it to the wall in small sections using a notched trowel, creating even ridges. Press each tile firmly into place with a slight twisting motion. Use tile spacers to maintain consistent gaps. Work in manageable sections to prevent the adhesive from drying out.
  5. Finesse the Cuts Around Fixtures. Measure and mark tiles that need cutting for edges, corners, or around fixtures like shower heads and faucets. Use a wet tile saw for straight cuts and a tile nipper for small adjustments. Take your time with these cuts as they're often the most visible. Test fit each piece before applying adhesive.
  6. Seal and Waterproof Completely. After the adhesive has cured for 24 hours, remove spacers and apply grout using a diagonal sweeping motion with a rubber float. Work grout into all joints thoroughly, then clean excess with a damp sponge. Once grout has cured, apply caulk around all edges where tile meets tub, corners, and fixtures. Use painter's tape for clean caulk lines.
