Installing Plastic Shower Panels: A Diy Guide

how to install plastic shower panels

Installing plastic shower panels is a great way to upgrade your bathroom with a stylish and durable option. PVC shower panels, in particular, offer water resistance, low maintenance, and a wide range of design options. The installation process is relatively straightforward and can be done as a DIY project with the right tools and some time. This process typically involves measuring and preparing the surface, cutting and fitting the panels, applying adhesive, and sealing the joints and edges. Proper maintenance and care will ensure that your plastic shower panels provide years of durability and enhance the overall aesthetic of your bathroom.

Measure and cut the panels

To measure and cut the panels, start by measuring the dimensions of your shower area using a measuring tape. Mark the measurements on the PVC panels, indicating where they need to be cut to fit. You can use strips of masking tape to mark the cut lines, which will help you achieve a cleaner cut.

Use a fine-tooth saw or a utility knife to carefully cut the panels according to your measurements. Make sure to achieve accurate and clean cuts. If you need to trim the panels, it is recommended to trim the edge that abuts a wall, rather than where two panels meet. For large panels, you can use a track saw or a circular saw with a cutting guide.

After cutting, dry-fit the panels to ensure they align correctly and fit snugly against the walls. Make any necessary adjustments to the panel sizes. You can also dry-fit the corner panels, ensuring a slight overlap with the other panels. Mark the position for the left and right sides with a pencil, which will guide you during the installation.

Before installing, cut holes in the shower wall for the shower trim handle and tub spout. Measure the distance from the vertical line to the centre of the tub spout and trim handle on the plumbing wall. Measure up from the top of the tub to ensure the measurements are consistent.

Prepare the surface

To prepare the surface for installing plastic shower panels, you should first measure the dimensions of your shower area. Use a measuring tape to take measurements and then transfer these to the plastic panels, marking where you need to cut them to size.

Next, ensure the walls are clean, dry, and free from any loose debris. Remove any existing tiles, wall coverings, or substrates if necessary. If your existing shower base is in poor condition, consider replacing it. Repair any damaged or uneven areas, ensuring a smooth and level surface.

Now, cut the panels using a fine-tooth saw or utility knife. Carefully cut the plastic panels according to your measurements, ensuring accurate and clean cuts. If you need to trim the panels for a better fit, use masking tape to mark the panel, giving you a definitive line and a cleaner cut. You can also use masking tape to hold the panels in place while you work.

Before installing the panels, cut holes in the shower wall for the shower trim handle and tub spout. Measure the distance from the vertical line to the centre of the tub spout and trim handle on the plumbing wall. These measurements should be the same if everything is in line. Then, measure up from the top of the tub to the spout and trim handle.

Apply adhesive

When you're ready to begin installing your plastic shower panels, start by choosing a waterproof adhesive that is suitable for PVC panels and can be used in wet environments. You will need to apply the adhesive directly to the back of the panel, ensuring full coverage.

Work quickly so that the adhesive doesn't have time to develop a skin. An adhesive that bonds to most surfaces and is repositionable for several minutes after installation is ideal. Using an adhesive spreader or notched trowel, apply the adhesive evenly to the back of the panel.

If you are installing interlocking panels, do not apply adhesive to more than one section at a time. Apply the adhesive to the back of the panel and install it, pressing it into place. You may need a helper to ensure the joints are tight. If the adhesive isn't holding the panels securely, you may need bracing boards.

If you are installing panels with flattened edges (flanges), you can nail them directly to the wall studs. Drill pilot holes to ensure you don't split the flange. If your unit has pre-drilled holes, simply screw the panel into the stud at the indicated points.

Install the panels

Now that you have measured the area, prepared the surface, and cut the panels to the appropriate size, it's time to install the panels.

Before installing the panels, cut holes in the shower wall for the shower trim handle and tub spout. On the plumbing wall, measure the distance from the vertical line to the centre of the tub spout and trim handle. These measurements should be the same if everything is in line. Then, measure up from the top of the tub to the spout and the trim handle as well.

If you are installing interlocking panels, line up the side panels with the front edge of the shower pan or bathtub. Use strips of masking tape to hold each panel in place. Dry fit the corner panels, ensuring a slight overlap with the panels. Confirm that all the pieces fit together and line up with the reference mark you made earlier. Then, remove the corner panels, followed by the side and back panels. Use a pencil to mark the position for the left and right sides.

If you are installing individual panels that connect together, place the back shower wall against the studs and lower it down onto the base. Make sure it is seated correctly and firmly on the shower pan. If your unit has pre-drilled holes, simply screw it into the stud at the indicated points. If not, use a 3/8-inch bit to drill pilot holes through the flange. Insert the side panel and make sure it is seated properly on the shower base.

Apply adhesive to the back of the panels. Work quickly so that the adhesive doesn't have time to develop a skin. Use an adhesive spreader or notched trowel to apply the adhesive evenly, ensuring full coverage. Starting from the bottom corner of the shower area, gently press the first back-wall panel into place. Apply a bead of colour-matched seam sealer to the tongue on the panel. Then, install the next panel by applying adhesive to the back and seam sealer to the tongue-and-groove joint. Repeat this process for the remaining panels, wiping off any excess seam sealer with denatured alcohol.

If the adhesive isn't holding the panels securely in place, you may need bracing boards to support them.

Seal the panels

Sealing the panels is a crucial step in the installation process to prevent leaks and ensure a watertight finish. Here is a detailed guide on how to seal plastic shower panels:

Prepare the Surface:

Start by putting on protective gloves, as silicone can irritate the skin. Remove any existing sealant or silicone using a sharp knife or a sealant stripping tool. Be careful not to scratch the surface of the shower panels or the tray. Clean any residual silicone or sealant with a clean, damp cloth. You can use white spirit or vinegar to remove stubborn residue. Ensure the surface is completely dry before proceeding to the next step.

Applying the Sealant:

Use tape to mark the path of the new sealant if you want to prevent it from spreading onto the wall panels or shower tray. Apply an even bead of silicone sealant along the groove or the line marked by your tape. Use a sealant finishing tool to spread the silicone evenly and smoothly over the area. Wipe away any excess sealant with a clean cloth.

Drying and Installation:

Allow the silicone to dry completely before using the shower. The drying time can vary, but it is generally recommended to wait for at least 24 hours. Some sources suggest waiting for up to 48 hours to ensure the sealant is completely dry. Once the sealant is dry, you can install your new plastic shower seal. Test for leaks after installation to ensure your shower screen is thoroughly sealed.

It is important to regularly inspect and maintain your shower panels and seals. Over time, the seals can become mouldy, worn, or broken, leading to potential leaks. Aim to reseal your shower panels every 1 to 2 years to maintain the integrity and appearance of your shower.
