Replacing a shower drain flange is a common plumbing task that can be done easily with the right tools and knowledge. Over time, the flange may become worn or damaged, causing leaks or other plumbing issues. In this article, we will guide you through the step-by-step process of replacing a shower drain flange to ensure a leak-free and properly functioning shower.

Tools and Materials You Will Need

Before getting started, gather the necessary tools and materials:

  • Adjustable wrench
  • Plunger
  • Screwdriver
  • Pipe cutter
  • New shower drain flange
  • Plumber’s putty
  • Plumbing tape
  • Plastic gloves
  • Towels

Step 1: Prepare the Shower Area

Start by removing any items from the shower area and placing towels on the floor to catch any water or debris that may fall during the process. This will help protect your bathroom from potential damage.

Step 2: Remove the Old Flange

Use the screwdriver to remove the screws holding the old flange in place. Once the screws are removed, gently lift the old flange and pull it out of the drain. If the flange is stuck, use the plunger to create suction and loosen it.

Step 3: Clean the Drain

After removing the old flange, clean the drain thoroughly to remove any debris or residue. Use a pipe cleaner or a small brush to scrub the area around the drain.

Step 4: Measure and Cut the Pipe

Measure the height of the pipe and use a pipe cutter to cut it to the appropriate length. Ensure that the cut is clean and even to ensure a proper fit for the new flange.

Step 5: Apply Plumber’s Putty

Take a small amount of plumber’s putty and roll it into a thin rope. Apply the putty around the bottom edge of the new flange. This will create a watertight seal between the flange and the shower floor.

Step 6: Insert the New Flange

Insert the new flange into the drain, making sure it sits flush with the shower floor. Press down firmly to ensure a tight seal with the putty.

Step 7: Secure the Flange

Use the screws provided with the new flange to secure it in place. Tighten the screws evenly to ensure a secure fit.

Step 8: Apply Plumbing Tape

Wrap plumbing tape around the threads of the drain pipe before connecting it to the new flange. This will create a tight seal and prevent any leaks.

Step 9: Reassemble the Shower

Reassemble the shower by attaching the drain pipe to the new flange. Use the adjustable wrench to tighten the connections and ensure a secure fit. Test the shower for any leaks before proceeding.

Step 10: Clean Up

Once you have confirmed that there are no leaks, clean up the area by removing the towels and any other debris. Dispose of the old flange and any other waste properly.


Replacing a shower drain flange is a relatively simple task that can be done by following these steps. By taking the time to replace a worn or damaged flange, you can prevent leaks and other plumbing issues in your shower. Remember to always wear gloves and take necessary safety precautions when working with plumbing fixtures.
