Step-by-Step Preparation

1. Identify the Type of Drain

Before beginning, identify the type of shower drain installed in your bathroom. Common types include compression, screw-in, and snap-in drains.
The removal and installation method may vary depending on the design.

2. Shut Off Water Supply

While replacing a shower drain usually doesn’t require shutting off the main water supply, it’s good practice to prevent any accidental splashes or leaks during the process.

3. Protect the Shower Floor

Use a towel or protective sheet around the drain opening to prevent tools or debris from scratching your shower floor.

Removing the Old Shower Drain

Step 1: Loosen and Remove Screws or Retainers

If the drain has a cover plate, unscrew it using a screwdriver. For snap-in drains, gently pry up the cover using a flathead screwdriver.

Step 2: Remove the Drain Body

Use pliers or a drain removal tool to loosen and lift out the drain body. In older installations, mineral deposits or rust may make this step more challenging, so be patient.

Step 3: Clean the Opening

Thoroughly clean the drain opening, removing old plumber’s putty or silicone. This ensures a smooth surface for the new installation.

Installing the New Shower Drain

Step 1: Apply Sealant

Place a bead of plumber’s putty or silicone sealant around the underside of the drain flange. This prevents leaks and keeps the drain secure.

Step 2: Insert the New Drain

Carefully insert the new drain body into the opening, ensuring it sits flush with the shower floor.

Step 3: Secure the Drain

Tighten the drain body according to the manufacturer’s instructions. Over-tightening can damage the drain or shower base, so apply balanced pressure.

Step 4: Install the Cover

Attach the new cover plate and ensure it’s firmly in place.

Ensuring Proper Sealing and Leak Prevention

• Check for gaps around the drain body.
• Apply additional silicone if needed.
• Run water and observe for any leaks underneath the shower.

Post-Replacement Maintenance Tips

• Clean the drain cover regularly to prevent clogs.
• Avoid harsh chemicals that could damage the sealant.
• Inspect for leaks every few months.
• Use a hair trap to minimize blockages.
