How to Build a Shower Pan with a Linear Drain
A linear drain shower pan offers a sleek, modern look and provides a unique showering experience. It's also easier to clean than a traditional shower pan with a round drain. Here's a step-by-step guide on how to build a shower pan with a linear drain:
Step 1: Prepare the Subfloor
- Level the Subfloor: Ensure the subfloor is level and solid. Use a level and shims to correct any unevenness.
- Install a Waterproof Membrane: Apply a waterproof membrane over the subfloor. This will prevent water from leaking into the subfloor. There are many options available, such as PVC membrane, Schluter Kerdi, or other similar products.
- Install the Linear Drain: Position the linear drain where you desire, ensuring it's level and plumb. Install the drain according to the manufacturer's instructions. You may need to cut the drain to fit your specific shower pan size.
Step 2: Install the Mortar Bed
- Mix the Mortar: Mix the mortar according to the manufacturer's instructions. The mortar should be a consistency similar to peanut butter.
- Apply the Mortar: Use a trowel to apply the mortar to the subfloor, starting from the lowest point of the shower pan. The mortar should be about 1.5-2 inches thick, with a slight slope towards the linear drain.
- Install the Shower Pan Liner: Place the shower pan liner over the mortar bed. The liner should be large enough to extend beyond the edges of the shower pan.
Step 3: Install the Shower Pan
- Secure the Liner: Use a sealant to secure the liner to the edges of the shower pan.
- Install the Shower Pan: Place the shower pan on top of the liner. Ensure it's level and aligns with the linear drain. Secure the shower pan to the subfloor using screws or nails.
- Seal the Shower Pan: Apply sealant around the edges of the shower pan and the liner to prevent leaks.
Step 4: Install the Tile
- Prepare the Tile: Cut the tiles to fit the shower pan. Ensure that the tiles are correctly placed to create a smooth transition around the linear drain.
- Apply Mortar to the Tile: Apply a thin layer of mortar to the back of the tile.
- Place the Tile: Place the tile onto the shower pan, pressing it firmly into the mortar.
- Grout the Tile: Once the mortar has dried, grout the tiles, ensuring to fill all the gaps between the tiles and around the drain.
Step 5: Final Touches
- Clean the Grout: Clean the grout with a damp cloth to remove any excess grout.
- Apply Sealant: Apply a sealant to the grout to protect it from water damage.
Tips
- Hire a Professional: If you are not comfortable with the process, hire a professional contractor to build the shower pan.
- Check for Leaks: Test for leaks after each stage of the installation process.
- Use Quality Materials: Use high-quality materials to ensure the durability of the shower pan.
- Plan and Measure Carefully: Accurate measurements and planning will ensure a smooth and successful installation.
Building a shower pan with a linear drain requires careful planning and execution. By following these steps and paying attention to detail, you can create a beautiful and functional shower space.
