Tired of the ఠ_ఠ look of your fiberglass shower? Tile can breathe new life into your bathroom, creating a luxurious, durable, and easy-to-clean space. Replacing a fiberglass shower with tile involves careful planning and execution, but with the right steps, you can achieve a stunning result. Let’s dive into the process, step-by-step.
Before we start, remember that tiling a shower requires patience, precision, and the right tools. It’s a significant project that can take several days, so make sure to set aside enough time. Also, safety is paramount when handling tools and materials, so always wear appropriate personal protective equipment (PPE).

Preparation and Demolition
Preparation is key to a successful tile installation. Before you start, gather all necessary tools and materials. You’ll need a utility knife, screwdriver, pry bar, reciprocating saw, trowel, notched trowel, grout float, rubber grout float, tile nippers, wet saw,.tile spacers, thinset mortar, grout, and of course, your chosen tiles.
Once you have everything ready, it’s time to start demolition. Turn off the water supply to the shower and remove any fixtures. Use a reciprocating saw to cut through the fiberglass and a pry bar to remove it in sections. Be careful not to damage the surrounding walls and floor. Remove any loose or damaged concrete backer board and clean the area thoroughly.
Waterproofing and Backer Board Installation
Before laying new tile, ensure your shower is waterproof. Apply a liquid membrane waterproofing agent to the walls and floor. Allow it to dry according to the manufacturer’s instructions. Once dry, install pressure-treated, cement-backer board. Begin at the bottom, working your way up, and use盝 screws to secure it to the wall studs. Ensure the backer board is well-supported and accurately aligned.
Seal the seams and corners with backer board tape and waterproofing compound. Let it dry completely. This step is crucial to prevent moisture from migrating behind your tile and causing damage. Before tiling, snap chalk lines on the walls and floor to help ensure your tiles are level and evenly spaced.

Laying the Tile
Mix your thinset mortar according to the manufacturer’s directions. Using a notched trowel, apply the mortar to the backer board in small sections. Work quickly and evenly to ensure the mortar doesn’t dry out before you can set your tile. Press the tile firmly into the mortar, using spacers to ensure even grout lines.
Start tiling from the center of the shower floor, working your way out. This helps ensure the pattern is symmetrical. Larger format tiles require fewer cuts, so if your wall height allows, consider using them. For cut tiles, use a wet saw or tile nippers. Allow the mortar to cure according to the manufacturer’s instructions before grouting.
Grouting and Sealing
Mix your grout according to the package instructions. For shower grout, use a sandless or low-sand mix for ease of cleaning and better mold resistance. Apply the grout with a float, working diagonally across the joints to force the grout into the space. Allow the grout to set for about 15 minutes, then use a damp sponge to remove excess grout from the tile surface.

Clean the tile face with a damp cloth or sponge, folding it to get a clean edge. Allow the grout to haze for about 15-20 minutes, then clean it off using a damp sponge. Let the grout cure for 72 hours before washing the shower. Apply a grout sealer to protect the grout from moisture and stains. Allow the sealer to cure according to the manufacturer’s instructions.
Reinstalling Fixtures and Final Touches
Once the grout and sealer are fully cured, reinstall your shower fixtures. Turn on the water supply and test the shower to ensure everything works correctly. Inspect your tile work for any missed spots or chips, and touch up as needed.
Finally, step back and admire your handiwork. The last step is to clean the shower thoroughly, removing any residual grout or sealer. Regular maintenance, such as cleaning mold and mildew off the tiles, will keep your shower looking beautiful for years to come.
