How to install linear shower drain

Installing a linear shower drain can transform your bathroom, providing a sleek and modern look while improving drainage efficiency. This guide is designed for DIY enthusiasts, homeowners, and professionals in the construction or plumbing industry who want to understand the step-by-step process of installing a linear shower drain. We will cover everything from the necessary tools and materials to detailed installation steps, ensuring you can complete this project with confidence.

Linear shower drains have become increasingly popular due to their minimalist design and superior functionality. Unlike traditional center drains, linear drains allow for a single slope in the shower floor, making them ideal for larger tiles and providing a more accessible, barrier-free shower experience. This article will walk you through the installation process, ensuring you achieve a professional finish.

Terms Explanation

Linear Shower Drain: A type of drain that is long and narrow, typically installed along one edge of the shower floor, allowing water to flow in a single direction.

Mortar Bed: A mixture of sand, cement, and water used to create a solid, level base for tiling.

PVC Cement: A type of adhesive used to bond PVC pipes and fittings.

Task Step Guide

Step 1: Gather Tools and Materials

Before starting, ensure you have all the necessary tools and materials:

• Linear shower drain kit

• Measuring tape

• Level

• Mortar mix

• Notched trowel

• PVC pipe and fittings

• PVC cement

• Tile and grout

• Waterproof membrane

• Utility knife

• Bucket and sponge

Step 2: Prepare the Shower Area

Start by removing any existing flooring and ensuring the subfloor is clean and level. Measure and mark the location where the linear drain will be installed. The drain should be positioned at the lowest point of the shower floor to ensure proper drainage.

Step 3: Install the Drain Base

Place the linear drain base in the marked location. Connect the drain to the existing plumbing using PVC pipe and fittings. Apply PVC cement to the connections to ensure a watertight seal. Use a level to make sure the drain base is perfectly horizontal.

Step 4: Create the Mortar Bed

Mix the mortar according to the manufacturer's instructions. Spread the mortar evenly over the subfloor using a notched trowel, creating a slope towards the linear drain. The slope should be approximately 1/4 inch per foot to ensure proper water flow. Allow the mortar to cure for the recommended time.

Step 5: Apply Waterproof Membrane

Cut the waterproof membrane to fit the shower floor and walls, extending it up the walls by at least 6 inches. Apply the membrane over the cured mortar bed, ensuring there are no wrinkles or air bubbles. Seal the edges and corners with waterproof tape or adhesive.

Step 6: Install the Linear Drain

Place the linear drain on top of the waterproof membrane, aligning it with the drain base. Secure the drain in place according to the manufacturer's instructions. Ensure the drain is level and properly aligned with the shower floor slope.

Step 7: Tile the Shower Floor

Begin tiling the shower floor, starting from the drain and working your way outwards. Use a notched trowel to apply thin-set mortar to the back of each tile, pressing them firmly into place. Ensure the tiles are level and follow the slope towards the drain. Allow the thin-set mortar to cure for the recommended time.

Step 8: Grout the Tiles

Mix the grout according to the manufacturer's instructions. Apply the grout to the tile joints using a rubber float, pressing it firmly into the gaps. Wipe away excess grout with a damp sponge, being careful not to remove grout from the joints. Allow the grout to cure for the recommended time before using the shower.

Tips and Reminders

• Ensure the subfloor is level before starting the installation to prevent water pooling.

• Double-check all measurements and levels to ensure proper alignment and drainage.

• Allow sufficient curing time for mortar and grout to ensure a durable and long-lasting installation.

• Use a high-quality waterproof membrane to prevent water damage and mold growth.

• Consult the manufacturer's instructions for specific installation details and recommendations.

Installing a linear shower drain can significantly enhance the functionality and aesthetics of your bathroom. By following this step-by-step guide, you can achieve a professional-quality installation that ensures efficient drainage and a sleek, modern look. Remember to take your time, double-check your work, and consult the manufacturer's instructions for the best results.
