Step 1: Planning the installation
The first and most important step is to plan your Oatey linear shower drain layout and placement. You need to think it through and imagine doing all the steps in your head. Of course, things don’t always go as planned, but it helps with your confidence. So, this careful planning will prevent unwanted changes later.
Step 2: Measuring and Marking
Before starting to measure and mark, please note that there are four mounting options available for the linear shower:
- Three-sided wall.
- Free floor.
- Shower entrance floor.
Measure and draw drain lines depending on your preference. Remember that floor-mounted drains are less supported than wall-mounted ones.

Step 3: Drill the hole using a saw/cutter.
Hole perfection is the most important phase in fixing a linear shower. Measure the drain and calculate its height. Drain tops should be 1/16″ below adjacent tiles before grate covering.
Step 4: Prepare the Substrate
Prepare the shower substrate before installing the linear drain. Clean the area thoroughly and eliminate dampness and debris. The substrate must be level and sloping towards the drain to allow water to flow.
Step 5: Installing waterproof liner and clamp rings
Install shower liners after the mortar sets for 24 hours to prevent water damage. This is essential for installing a perfect linear shower drain. Shower liners must extend 6″ up the walls. Use clamp rings to fix the base drain liner and form a water barrier.
Step 6: Install the Drain Body
Insert the drain body into the substrate to begin installation. Completely cover the drain flange with waterproofing adhesive.
Furthermore, align the drain body with the specified spot and press it in. A spirit level should be used to level the drain before letting the adhesive dry, per the Oatey’s directions.

Step 7: Connect the Drain Outlet
After installing the drain body, connect the drain outlet to the plumbing. Thread seal tape or authorized sealants should be used to make all connections watertight. This phase requires following local plumbing codes to ensure operation and compliance.
After installing the drain body, connect the drain outlet to your plumbing system—Prioritize waterproof connections with thread seal tape or approved sealants.
Step 8: Install the Grate
After securing the drain body and outlet, apply the grate or cover. Choosing a grate that suits your decor and allows enough water flow enhances your bathroom.

Additionally, make sure the grate is level and matches your tile pattern. Follow the manufacturer’s instructions to install the grate to finish your Oatey linear shower drain’s look and function.
Step 9: Tile and seal cover
In the last installation steps, fill the liner with mortar at a 2-degree gradient or 1/4″ per foot slope towards the base drain. This thorough procedure ensures water drainage and installation lifetime. After installing shower tiles, carefully seal the drain with silicone. Also, ensure you use high-quality silicone caulk on the joints for a beautiful and durable shower finish.
