How to Refinish a Plastic Shower Base

A plastic shower base can become darkened by years of footprints, soap scum, body oils, and dirt. Though the surface may be clean, the stain will remain a slight discomfort for people who are in the shower stall. Refinishing a shower base is the best way to restore and clean the shower's floor surface. The refinishing job requires less than half a day's work and can work wonders for a bathroom's overall aesthetics.

Step 1

Clean the shower stall with household cleaners and wash off with water. Let it dry.

Step 2

Remove old caulking surrounding the shower pan with a flat-head screw driver. Clean up caulk debris.

Step 3

Clean the shower base with tri-sodium phosphate and a sponge to remove soap scum, oils, dirty, and old caulk. TSP is a very powerful cleaning agent. Wear protective goggles, a mask, and gloves. Keep away from skin and work in a well-ventilated area.

Step 4

Tape off the surrounding walls with plastic tarps and masking tape to prevent spills.

Step 5

Spray on epoxy spray paint on the shower base. Use a paint specifically designed for shower bases. Spray following the manufacturer's directions. Spray on three coats, letting each coat dry. Use fine-grit sandpaper to smooth any rough patches or overspray spots. Clean up any debris before spraying on another coat. Let it dry.

Step 6

Remove tarps and tape.
