How to Repair a Prefab Shower Floor

Prefab shower units are used in new homes and home renovations. You must make repairs, eventually, to the floor of your shower unit. The floor benefits greatly from resurfacing or just a good refreshing, periodically. However, bigger problems may require installing a replacement floor.

Moderate

Instructions

Things You'll Need

• Magnifying glass
• Duct tape
• Drill
• Shower floor
• Adhesive
• Sander

1. Take note of the manufacturer when your shower unit is new. You must know the name of the manufacturer when it is time for repairs.

2. Feel how the shower unit reacts when an adult steps in. A spongy floor shows weakness, which may indicate hairline cracks that must be repaired.

3. Check the shower floor for cracks, using a magnifying glass. Minute cracks leak water but cannot be seen by the naked eye. Cover large cracks with duct tape to add extra protection.

4. Drill holes through the existing prefab floor and leave it for a few days to allow the underneath area to dry. Fill these holes with special foam made to repair showers.

5. Buy just the floor that matches your unit. Manufacturers carry floor components that fit right into the shower. Place the new shower floor inside the unit over the existing floor. Make sure the drain hole matches up, and the floor fits tightly inside the shower.

6. Apply adhesive to all areas where the new floor meets the old shower unit. Seal the floor piece to the prefab walls and around the drain. Allow the adhesive to dry for several hours.

7. Sand all areas of the new floor unit, where it meets the old unit. Allow your new floor to set overnight before using your shower.
