How to Install a Shower Pan Linear Drain
A linear drain is a modern and stylish alternative to traditional round shower drains. They are sleek, easy to clean, and can add a touch of sophistication to any bathroom. Installing a linear drain requires some DIY skills, but it's a project that most homeowners can tackle with the right tools and instructions. Here's a step-by-step guide on how to install a linear drain shower pan:
1. Prepare the Shower Area
- Clear the area: Remove all existing fixtures and materials from the shower area, including the old drain.
- Level the subfloor: Ensure the subfloor is level and even, using a level and a trowel to adjust any uneven areas. You can use a self-leveling compound for smoother results.
- Install a moisture barrier: A moisture barrier is essential to prevent water damage and mold growth. Apply a waterproof membrane over the subfloor, overlapping the seams by at least 6 inches.
2. Install the Linear Drain
- Choose the right size: Select a linear drain that is the appropriate size for your shower pan. Consider the length of the drain and its water flow capacity.
- Position the drain: Determine the location of the drain, ensuring it's positioned at the lowest point of the shower pan.
- Install the drain body: Place the drain body in the chosen location and mark its outline on the subfloor. Cut the subfloor according to the markings and install the drain body, securing it with the provided fasteners.
3. Prepare the Mortar Bed
- Mix the mortar: Prepare a mortar bed using a pre-mixed mortar or a mixture of cement, sand, and water. The mortar should be a consistency similar to peanut butter.
- Apply the mortar bed: Spread the mortar bed evenly over the subfloor, ensuring it covers the entire area where the shower pan will be installed. The mortar bed should be thick enough to support the shower pan and provide a slope towards the drain.
4. Install the Shower Pan
- Position the shower pan: Carefully place the shower pan over the mortar bed, ensuring it's centered and aligned with the linear drain.
- Secure the shower pan: Use screws or adhesive to secure the shower pan to the mortar bed. Check that the drain is properly aligned and that the pan is level.
5. Connect the Drain to the Plumbing System
- Attach the drain pipe: Connect the drain pipe to the linear drain, ensuring a secure and leak-proof connection.
- Connect to the drain line: Connect the drain pipe to the existing drain line using appropriate fittings and adhesives.
- Test for leaks: Test the drain system for leaks before proceeding.
6. Finish the Installation
- Install the drain cover: Install the decorative drain cover, ensuring it is flush with the shower pan.
- Apply grout: Use grout to seal the edges of the shower pan and the drain cover.
- Clean and finish: Clean the shower pan and drain thoroughly, removing any excess mortar or grout. Allow the grout to cure before using the shower.
Safety Precautions:
- Always wear safety goggles and gloves when handling mortar and other building materials.
- Ensure the shower area is properly ventilated to avoid the buildup of fumes.
- Use caution when working with power tools.
- Consult with a professional plumber if you encounter any difficulties or have any concerns about the installation process.
By following these steps, you can successfully install a linear drain shower pan and enjoy the benefits of a modern and functional shower space.
