How to Remove a Shower Stall and Replace with Tile: DIY Guide

Removing an outdated shower stall and replacing it with a custom tiled shower is one of the most impactful renovations you can make to update a bathroom's aesthetic and value. Whether your current enclosure is stained, cracked, or simply feels dated, this project transforms a dated fixture into a timeless design element. While it requires careful planning and a methodical approach, the result is a durable, personalized space that reflects your style. This guide walks you through the entire process, from initial preparation to the final grout seal, ensuring a successful transformation.

Assessing Your Current Shower Configuration

Before swinging a hammer, it is essential to understand the specific type of shower stall you are dealing with, as this dictates the removal process. Modern showers are typically either prefabricated acrylic or fiberglass units that slide into place, while older installations might be built-in units set in mortar bed. Measuring the dimensions and identifying the wall materials—whether they are attached to studs or backed by cement board—will determine the scope of work. You will need to turn off the water supply to the bathroom and verify that the plumbing is accessible once the enclosure is removed. Taking photos of the current layout before disassembly can save significant time and prevent mistakes during the rebuild phase.

Tools and Materials Required for the Project

Successful demolition and tiling require a specific set of tools to handle both the destruction of the old enclosure and the precise work of new tile installation. You will need standard demolition tools such as a reciprocating saw, a pry bar, and a hammer to dismantle the stall and remove old flooring. For the tiling portion, invest in a notched trowel, a tile cutter or wet saw, and a good level to ensure even placement. Safety gear is non-negotiable; gloves, safety glasses, and a dust mask are mandatory. Finally, gather your materials, including the new tile, thin-set mortar, grout, membrane liner, and tile spacers, to ensure you are not mid-project waiting for a delivery.

Step-by-Step Removal of the Old Shower Stall

The demolition phase is the most physically demanding part of the project, requiring patience to avoid damaging surrounding walls or plumbing. Start by removing the shower door and any fixtures, such as the faucet handle or showerhead, to prevent them from becoming damaged or lost. If you have a prefabricated stall, locate the clips or brackets that secure the unit to the floor and walls, and remove them carefully. For built-in stalls, use a reciprocating saw to cut through the caulk and seams, then gently pry the unit away from the framing. Be prepared for a significant amount of dust and debris, so a shop vacuum should be used constantly to keep the area clean and safe.

Preparing the Subfloor and Plumbing

Once the old stall is entirely cleared, you must inspect and prepare the substrate to ensure a stable and waterproof foundation for the tile. If the old mortar bed is uneven or crumbling, you will need to remove it entirely and install a new cement board or a sturdy foam backer board. This is the critical moment to check the plumbing for leaks; inspect the drain, valve trim, and water lines, replacing any components that show signs of wear. Slope the subfloor slightly toward the drain to prevent water pooling, and install a waterproofing membrane or a vapor barrier according to manufacturer instructions. This step is vital for preventing moisture intrusion that could rot the framing or cause mold behind the tiles.

Layout, Setting, and Grouting the Tile

With a pristine, level surface ready, you can move on to the creative phase: laying the tile. Begin by determining your pattern—straight stack, herringbone, or offset—and dry-lay the tiles to visualize the final look and identify cuts needed. Mix the thin-set mortar to the correct consistency and use the notched trowel to apply it evenly to the substrate, pressing each tile firmly into place. Utilize tile spacers to maintain consistent grout lines, ensuring a professional finish. After the adhesive has cured, apply the grout diagonally across the tiles, forcing it into the joints. Once the grout has set, clean the surface with a damp sponge to reveal the polished tile without leaving any residue in the crevices.

Final Sealing and Reinstallation

The final steps protect your investment and ensure the longevity of the shower. Apply a high-quality grout sealer to the joints to prevent staining and moisture penetration, following the manufacturer's curing time. Reinstall the drain cover and reinstall any fixtures you removed at the start of the process. Turn the water supply back on and test the shower thoroughly, checking the drain for proper flow and inspecting the corners for any signs of leakage. With the old stall removed and new tile installed, you have created a beautiful, waterproof surface that will last for years with minimal maintenance.
