How to Install a Bathtub Surround Over Tile

Replacing outdated or damaged tile around a bathtub is a significant undertaking. However, a cost-effective and less labor-intensive alternative exists: installing a bathtub surround directly over the existing tile. This method saves time and effort by eliminating the need for demolition and tile removal. This article provides a step-by-step guide on how to successfully install a bathtub surround over tile, transforming a bathroom quickly and efficiently.

Preparing the Existing Tile Surface

Proper surface preparation is crucial for a successful installation. The existing tile must be thoroughly cleaned to remove any soap scum, mildew, or grime that might prevent the adhesive from bonding correctly. A strong alkaline cleaner is recommended for this purpose. After cleaning, the tile surface should be rinsed thoroughly and allowed to dry completely.

Next, any loose or damaged tiles need to be addressed. Loose tiles should be re-secured with tile adhesive or thin-set mortar. Chipped or cracked tiles should be repaired with epoxy or a similar filler. Ensuring a smooth, even surface is vital for the proper adhesion and appearance of the new bathtub surround.

Finally, the entire tile surface should be lightly sanded to improve adhesion. This roughens the surface, creating a better grip for the adhesive. Use a fine-grit sandpaper and wipe away all dust after sanding. Any caulking around the tub or fixtures should be removed and replaced with fresh caulk after the surround is installed.

Choosing and Measuring for the Bathtub Surround

Bathtub surrounds come in various materials, including acrylic, PVC, and composite. Acrylic surrounds are popular due to their affordability, durability, and ease of installation. PVC surrounds offer excellent water resistance and are also easy to clean. Composite surrounds provide a more high-end look and feel. The choice depends on budget, desired aesthetic, and practical considerations.

Accurate measurements are essential for selecting the correct size surround. Measure the width and height of the area to be covered, taking into account any fixtures like showerheads or faucets. If the existing tile extends beyond the standard dimensions of a prefabricated surround, custom sizing might be necessary. Precise measurements will ensure a proper fit and minimize the need for adjustments during installation.

When choosing a surround, consider the existing plumbing fixtures. Ensure the chosen surround accommodates the placement of the faucet, showerhead, and spout. Some surrounds come with pre-drilled holes, while others require cutting openings during installation. Carefully measure and mark the locations of these fixtures before cutting any holes.

Installing the Bathtub Surround

Before beginning the installation, gather all the necessary tools and materials, including adhesive, caulking gun, utility knife, measuring tape, level, and safety glasses. Dry-fitting the surround before applying adhesive is highly recommended. This allows for any necessary adjustments and ensures a proper fit.

Apply a generous amount of adhesive to the back of the surround, following the manufacturer's instructions. Specific adhesives are designed for use over tile and provide a strong, lasting bond. Spread the adhesive evenly to ensure complete contact with the tile surface. Position the surround carefully and press it firmly against the tile, ensuring it is level and plumb.

Once the surround is in place, secure it further using finishing nails or screws. These fasteners should be placed in areas that will be covered by trim or caulking. After securing the surround, apply a bead of caulk around the edges where it meets the wall and tub to create a watertight seal. This prevents water from seeping behind the surround and causing damage.

Finally, install any necessary trim pieces to cover the edges of the surround and provide a finished look. Trim pieces are typically secured with adhesive or clips. Allow the adhesive and caulk to cure completely before using the bathtub or shower, typically 24 to 48 hours, following the manufacturer's guidelines.
