How to Install Oatey Shower Drain

How to Install Oatey Shower Drain: Installing a shower drain is a fundamental part of any bathroom renovation or construction project. The Oatey shower drain is a popular choice due to its durability and efficient design. In this comprehensive guide, we’ll take you through the step-by-step process of installing an Oatey shower drain, ensuring a watertight and professional finish to your shower.

Materials and Tools You’ll Need

Before you start the installation process, make sure you have the following materials and tools ready:

  • Oatey shower drain kit
  • Screwdriver
  • Pipe wrench
  • Plumber’s putty
  • PVC primer and cement
  • Level
  • Teflon tape
  • Silicone sealant
  • Saw (if adjustments to the pipe length are needed)

Step 1: Gather the Necessary Information

Before purchasing your Oatey shower drain, measure the diameter of your shower drain pipe to ensure you get the correct size. Oatey offers various sizes, so having this information beforehand will prevent any delays.

Step 2: Prepare the Shower Base

Ensure your shower base is clean and free from debris. If you’re working on a new installation, follow the manufacturer’s instructions for preparing the shower base.

Step 3: Dry Fit the Oatey Drain

Before applying any sealant or adhesive, dry fit the Oatey shower drain to check for proper alignment and fit. This step ensures that adjustments can be made before committing to the final installation.

Step 4: Apply Plumber’s Putty

Once you’re satisfied with the dry fit, apply plumber’s putty to the underside of the drain flange. This putty creates a water-resistant seal between the drain and the shower base.

Step 5: Insert the Drain into the Pipe

Carefully insert the Oatey shower drain into the shower drain pipe. Use a twisting motion to ensure a secure fit. Wipe away any excess putty that may squeeze out.

Step 6: Tighten the Compression Gasket

Inside the drain, you’ll find a compression gasket. Use a screwdriver to tighten it securely. This gasket creates a watertight seal, preventing leaks.

Step 7: Secure the Drain Grate

Attach the drain grate by securing it with the provided screws. Ensure it sits flush with the shower base, maintaining a level surface.

Step 8: Connect the Drain to the Waste Pipe

Using a pipe wrench, connect the drain to the waste pipe. Apply Teflon tape to the threads to create a tight seal. Tighten the connection securely.

Step 9: Apply PVC Primer and Cement

If your shower drain and waste pipe are PVC, use PVC primer and cement to secure the connection. Follow the manufacturer’s instructions for proper application.

Step 10: Check for Level

Use a level to confirm that the shower drain and grate are level and flush with the shower base. Adjust if necessary to ensure proper drainage.

Step 11: Apply Silicone Sealant

Apply a bead of silicone sealant around the edges of the drain grate. This additional layer of sealant enhances the waterproofing and prevents any potential water damage.

Step 12: Allow the Sealant to Cure

Give the silicone sealant sufficient time to cure. Refer to the product instructions for the recommended curing time.

Step 13: Test the Drain

Once the sealant is cured, test the drain by running water into the shower. Check for any leaks and ensure proper drainage.

Step 14: Make Adjustments if Necessary

If you notice any issues during the test, make necessary adjustments. Tighten connections, reapply sealant, or consult the manufacturer’s guidelines for troubleshooting.

Step 15: Final Inspection

Perform a final inspection to ensure everything is secure, level, and watertight. This step is crucial for the long-term functionality of your Oatey shower drain.


Installing an Oatey shower drain is a manageable DIY project that enhances the functionality and aesthetics of your bathroom. By following these step-by-step instructions, you can confidently install the drain, knowing that it’s securely in place, preventing leaks and ensuring proper drainage for years to come.
