How to Install a Bathtub Surround: A Step-by-Step DIY Guide

Introduction

Installing a bathtub surround can be a practical and cost-effective way to give your bathroom a fresh look. With the right tools, preparation, and patience, it’s a project that can be completed in just a few hours. This guide will walk you through installing a bathtub surround, highlighting tips and best practices to help you avoid common pitfalls.

Tools and Materials Needed

Before you start, make sure you have the following tools and materials at hand:

Tools:

• Utility knife
• Hole saws or spade bits
• Carpenter’s level
• Caulking gun

Materials:

• Bathtub surround (3-piece or 5-piece)
• 4-5 tubes of tub surround adhesive
• Masking tape
• Mineral spirits
• Silicone sealant

Preparing the Bathroom Walls

Step 1: Wall Inspection Begin by inspecting the condition of the walls around the bathtub. The surface should be dry, clean, and mould-free. If installing the surround in a bathroom remodel, paint the walls beforehand. A freshly painted surface helps with waterproofing, but more importantly, it ensures that any exposed areas are adequately sealed.

If you’re installing over-existing tiles, ensure they are secure and clean. You can install a tub surround over old tiles, but they must be in good condition.

Step 2: Marking the Wall Once your wall surface is prepared, use a pencil and a carpenter’s level to lightly mark out the level and plumb lines where each surrounding piece will go. Be sure to position your lines so that they’ll be covered by the surround once installed—this way, you won’t have to remove them later.

Measuring and Cutting the Tub Surround

Step 3: Dry-Fit the Surround Panels Take each panel and dry-fit it into place. This step is crucial because it helps you visualize the final layout and ensures everything fits appropriately. Trim the panels to fit using a utility knife, hole saw, or spade bits if necessary. This is especially important if you’re installing around plumbing fixtures or windows.

Tip: Measure twice and cut once. Always use your marked lines to make precise cuts, and remember that minor adjustments may be necessary to get a snug fit.

Step 4: Cut Openings for Fixtures For panels that need openings for faucets or showerheads, use a hole saw or spade bit to cut these out carefully. Double-check that these cuts are in the correct position before proceeding.

Applying Adhesive and Installing the Panels

Step 5: Apply the adhesive Now, it’s time to attach the surrounding panels to the wall. Use the caulking gun to apply the tub surround adhesive in large vertical lines across the back of each panel. Avoid getting too close to the edges when applying adhesive, as this can cause excess adhesive to seep out when the panel is pressed against the wall.

Once the adhesive is applied, press the panel firmly against the wall, aligning it with your pre-drawn lines. Hold the panel in place for a few seconds, then carefully pull it away from the wall for about 1–3 minutes. This allows the adhesive to activate correctly.

Step 6: Secure the Panels After waiting 1–3 minutes, press the panel back onto the wall. Ensure that all edges are firmly pushed into place. Use masking tape to help hold the panels in place while the adhesive dries if necessary.

Repeat this process for all panels, ensuring they are aligned correctly and fit snugly into place. Clean off any excess adhesive with mineral spirits before it dries.

Sealing the Joints with Silicone

Step 7: Apply Silicone Sealant Once the adhesive has dried (usually 6–12 hours), you’re ready to seal the joints between the panels. Use a silicone sealant to create a waterproof barrier at all the joints, along the edges of the surround where it meets the bathtub, and around any fixtures.

Tip: Apply a smooth bead of silicone using your finger or a silicone tool to ensure an even finish. This step is critical for preventing leaks and water damage.

Let the silicone dry according to the manufacturer’s instructions (typically around 12 hours) before using the shower or bathtub.

Maintenance and Inspection

Step 8: Ongoing Maintenance: While the hard work is done, it’s essential to regularly inspect the sealed joints for any signs of wear or cracking. Over time, the silicone may break down and require resealing. Regular inspections can help prevent leaks and mould growth behind the panels.

Tip: Conduct a visual inspection of the silicone seams every few months, especially around high-use areas like the faucet and showerhead.

Common Mistakes to Avoid

• Not allowing the adhesive to cure correctly: Make sure you give the adhesive enough time to dry. Skipping this step can result in panels not sticking to the wall properly, leading to potential water damage.
• Cutting the panels incorrectly: Take your time when cutting the panels to fit around fixtures. Incorrect cuts can lead to gaps or improper alignment.
• Skipping the dry-fit step: Always dry-fit the panels before applying adhesive. This ensures everything will line up correctly when you can secure them permanently.

FAQs

How long does it take to install a 3-piece tub surround?

A 3-piece tub surround typically takes 1–2 hours to install. However, it would help if you waited for the adhesive to dry before applying silicone, which can extend the total time needed to complete the project.

Can I install a tub surrounded by the existing tile?

Yes, you can install a tub surrounded by the existing tile if the tiles are in good condition. Just ensure the surface is clean and free from mould or lose tiles.

What is the best adhesive for a tub surround?

The best adhesive for a tub surround is a high-quality, waterproof adhesive for bathroom use. Be sure to follow the manufacturer’s instructions for drying times.

How do I cut holes for faucets and fixtures?

Use a hole saw or spade bit to cut openings in the panels. Measure carefully to ensure the holes align perfectly with the plumbing fixtures.

Can I install a tub surround myself, or should I hire a professional?

While installing a tub surround is a manageable DIY project for most, it does require some basic skills and tools. If you’re unsure or have a complicated bathroom layout, you may want to consult a professional.
