Installing Tub Surround Over Drywall: A Step-by-Step Guide
Tub surrounds are a popular choice for bathroom renovations, offering a sleek and modern look that enhances the overall aesthetic of the space. However, installing a tub surround over drywall can be a challenging task, especially for DIY enthusiasts who lack experience with tile installation and drywall repair. In this article, we'll provide a comprehensive guide on how to install a tub surround over drywall, including the necessary materials, tools, and steps to follow.
Materials Needed
Before starting your project, make sure you have the following materials:
- Tub surround kit (includes panels, adhesive, and fasteners)
- Drywall repair compound
- Joint compound (also known as spackling compound)
- Paintable caulk
- Tiling adhesive (if using a tile surround)
- Ceramic tile (if using a tile surround)
- Grout (if using a tile surround)
- Notched trowel
- Putty knife
- Utility knife
- Hammer
- Taping knife
- Moisture-resistant drywall
Preparing the Surface
The first step in installing a tub surround over drywall is to prepare the surface. This involves ensuring the drywall is smooth and even, and filling any holes or gaps. Use a putty knife to apply drywall repair compound to any cracks or holes, and smooth it out with a taping knife. Allow the compound to dry completely before sanding it down with a fine-grit sandpaper.

Measuring and Marking the Surface
Next, measure the surface area of the tub surround and mark it onto the drywall with a pencil. Use a level to ensure the marks are straight and even. If using a tile surround, mark the location of the tile's center point, as this will help guide your cuts.
Cutting the Drywall
Use a utility knife or drywall saw to cut the drywall along the marked lines. If using a tile surround, cut the drywall to fit the tile's center point. Make sure to cut slowly and carefully to avoid damaging the surrounding drywall.
Installing the Surround
Begin installing the tub surround by applying adhesive to the back of the panels and pressing them firmly onto the drywall. Use a level to ensure the panels are straight and even, and tap them gently with a hammer to secure them in place. For tile surrounds, apply tiling adhesive to the back of the tile and press it firmly onto the drywall. Use a level to ensure the tile is straight and even, and tap it gently with a hammer to secure it in place.

Grouting and Caulking
After the adhesive has dried, use a grout float to apply grout between the tiles. Wipe away any excess grout with a damp cloth, and allow it to dry completely. Apply paintable caulk around the edges of the surround to create a seamless seal. For ceramic tile surrounds, grout the tiles as you would with a standard tile installation.
Tips and Tricks
Here are a few tips and tricks to keep in mind when installing a tub surround over drywall:
- Use a laser level to ensure the surround is perfectly level and plumb.
- Apply a thin layer of adhesive to the back of the panels to prevent gaps and ensure a smooth finish.
- Use a damp cloth to wipe away excess grout and prevent it from staining the surrounding surfaces.
- Apply caulk around the edges of the surround as soon as possible to prevent it from drying out.
- Consider using a tile surround with a built-in membrane to provide extra protection against water damage.

Installing a tub surround over drywall can be a challenging task, but with the right materials and tools, it's definitely doable.
