How to Prep a Bathtub for a Tub Surround

A tub surround helps control moisture in a bathroom.

Preparing a tub and bathroom for the installation of a new tub surround is a simple process. The process includes removing the old tub and preparing the area for a new surround. Adding waterproofing features helps deter the growth of mold and moisture inside the bathroom walls. Preparing for a new surround will probably take at least one day to complete.

Things You'll Need

• Screwdriver
• Utility knife
• Pry bar
• Hammer
• Safety glasses
• 1-inch nails
• Work gloves
• Electric saw
• 1-inch long screws
• Finishing nails
• Waterproof paint
• Paint roller
• Silicone caulk

Instructions

1. Remove the old shower surround if this surround job is a replacement rather than a new tub. Use a screwdriver to remove the faucet, shower head, faucet knobs and any other hardware from the tub.

2. Locate the edges of the old tub surround. They should extend from the top of the tub slightly. You will probably have to cut away some of the drywall surrounding the tub to get it to come out. Try to cut as straight lines as possible for a professional-looking job.

3. Pull the tub surround away from the wall. If it is glued, then you will have to pull away the entire drywall sheet. Use a pry bar, hammer and any other necessary tools to pull the surround walls away from the tub. Always wear safety glasses when working with drywall. When finished, all of the surround and drywall should be removed from above the tub.

4. Remove any moldy insulation and replace it with new insulation. Wear gloves when working with insulation. Install a few 2-by-4 boards between the studs in the wall to create a surface for the surround to stick to. Nail the boards in place with 1-inch nails. Attach the wall studs to the lip of the tub with screws or nails.

5. Cut the drywall sheets to fit in the holes left by the removal of the old surround. Nail new drywall sheets around the tub if you are installing a new acrylic, tile or fiberglass surround. Mark on the drywall sheets the placement of the studs for easier access when installing the surround. Nail the drywall to the studs with finishing nails.

6. Paint the surface of the drywall with waterproof paint to create a moisture barrier. Use silicone caulk on all seams in the drywall and between the walls and the tub. This adds additional barriers to water damage.
