Quartz ShowerPoint Square Shower Drain Installation Guide
The Quartz ShowerPoint Square Shower Drain is designed to provide dependable drainage while delivering a clean, contemporary appearance for tiled showers. Its durable construction and clamping drain design make it compatible with traditional vinyl, CPE and other approved waterproofing membrane systems used in residential and commercial shower installations.
This installation guide explains the recommended installation process for showers using waterproof membranes beneath the mortar bed. Following these instructions will help create a watertight shower system that directs water efficiently to the drain while protecting the surrounding structure from moisture damage.
The installation details shown in this guide provide a practical reference for builders, tile contractors, remodelers and homeowners. While every project may have unique requirements, the procedures outlined here represent proven installation methods suitable for most tiled shower applications.
Before You Begin
Before starting the installation, verify that the shower framing, plumbing and subfloor have been completed according to local building codes. Confirm that the drain location is correctly positioned, all plumbing connections are secure and the waterproofing materials are compatible with the selected drain assembly.
Whenever floor joists require cutting, drilling or modification, consult a qualified structural engineer before making alterations. Proper structural support is essential to maintain the strength of the floor system and ensure long-term performance of the finished shower.
Step 1: Prepare the Shower Framing
Construct the shower enclosure and frame the shower opening according to the project plans. Install any required blocking around the perimeter to support the waterproofing membrane and provide a solid foundation for the finished shower assembly.
Step 2: Install the Drain Flange
Connect the lower section of the ShowerPoint drain flange to the waste pipe and verify that it is securely fastened and properly aligned. Leave the drain bolts in place and temporarily block the drain opening with a clean rag or protective plug to prevent mortar or construction debris from entering the plumbing during installation.
Step 3: Prepare the Mortar Bed
Apply the mortar evenly across the shower subfloor, creating a solid and stable base for the waterproofing membrane. Ensure the surface is smooth and properly shaped before installing the membrane to eliminate voids that could affect the finished installation.
Step 4: Install the Waterproofing Membrane
Install an approved CPE, vinyl or compatible waterproofing membrane over the prepared mortar bed. Reinforce the membrane around the drain opening and carefully trim the material to expose the drain outlet and the flange bolt locations. Proper membrane installation is essential to prevent water from penetrating the shower structure and causing long-term moisture damage.
Follow the waterproofing membrane manufacturer's installation instructions and allow the membrane to lay flat without wrinkles or gaps before securing it to the drain assembly.
Step 5: Secure the Clamping Drain Flange
Install the upper section of the drain flange and tighten the bolts evenly to securely clamp the waterproofing membrane between the two flange sections. This compression creates a watertight seal that directs water into the drain while protecting the subfloor beneath the tile installation.
Step 6: Perform a Water Test
Before continuing with the tile installation, plug the drain and fill the shower base with water to perform a leak test. Leave the water in place for at least 24 hours or as required by local building codes to verify that the waterproofing system is completely watertight.
If any leaks are detected, repair the waterproofing membrane before proceeding with the remaining installation steps.
Step 7: Install and Adjust the ShowerPoint Drain
After the waterproofing system has successfully passed the water test, install the ShowerPoint drain body and adjust it to the correct finished height. Ensure the drain will be flush with the completed tile surface and verify that it remains level in all directions before placing the final mortar bed.
Step 8: Install the Final Mortar Bed
After the drain has been adjusted to the proper height, place the final mortar bed around the drain assembly. Allow for the thickness of the tile and thin-set mortar while creating a consistent slope of at least 1/8 inch per foot (1%) toward the drain. A properly sloped shower floor promotes efficient drainage and helps prevent standing water.
Step 9: Install Tile and Grout
Once the mortar bed has fully cured, apply a quality thin-set mortar and install the shower floor tile. Maintain uniform grout joints and ensure the finished tile surface remains flush with the top of the drain frame. After the tile adhesive has cured, grout the installation according to the grout manufacturer's recommendations.
Step 10: Install the Drain Grate
Clean the drain body thoroughly to remove any mortar, grout or construction debris before placing the decorative grate into the ShowerPoint drain. Verify that the grate sits securely and is level with the finished tile surface for proper drainage and a professional appearance.
