Drain Types: Know Before You Begin

- Screw-in drains require more effort but offer a secure fit.
- Compression drains are ideal when access below is limited.
Step-by-Step: How to Replace Shower Drain
Step 1 – Remove the Old Drain
Use a screwdriver or wrench to unscrew the old drain. If it’s stuck due to mineral buildup or corrosion, apply penetrating oil and try again after a few minutes.
Step 2 – Clean and Inspect the Area
Wipe away debris and check the condition of the surrounding material. Ensure the floor is dry and structurally sound.
Step 3 – Install the New Drain
Apply plumber’s putty or silicone to the underside of the drain flange. Insert the new drain, screw it in tightly, and secure it from beneath if possible.
Step 4 – Test the Seal
Run water through the shower and watch for leaks. It’s better to catch issues now than after the shower is sealed and in use.

- If your drain is inaccessible from below, use a retrofit drain
- Avoid over-tightening—especially on plastic or fiberglass bases
- Always apply sealant generously to avoid gaps
- Use rust-resistant drain materials in high-moisture homes
