Follow these steps, and we’ll show you how to install bathroom wall panels to remodel your bathroom.

Get the Right Tools and Supplies

Ensure you have all the necessary tools to do the best job. To install bathroom wall panels, you need:


Handsaw, jigsaw, or circular saw




1200mm level

Sealant gun


Tape measure

Additionally, it’s recommended to invest in Witop Decor products: Sureseal Strips and Showerwall Sealant.


Prepare the Bathroom

Clean the Area: Ensure the wall is clean, degreased, and free of dirt and dust.

Check the Wall: Make sure the wall is flat and perpendicular using a level.

Ensure the Fixing Method is in Place

If they are not already in place, treated slats must be used as a fixing method.


Install Wooden Slats: Use wooden slats of uniform thickness (approximately 25mm x 50mm) fixed vertically in the center of 585mm for 585mm panels. Ensure all vertical panel joints are supported by vertical slats.

Spacing: Determine the slat spacing to suit the specific panel width you are installing.

Vertical and Parallel Slats: Install all slats vertically and parallel, using packing gaskets to ensure they are completely vertical and level.

Support Heavy Objects: Place additional slats to support heavy objects such as washbasins, wall-mounted toilets, or furniture. Use vertical slats to support corner contours.

Install the Shower Tray

Check Level: Use a spirit level to ensure the shower tray is horizontal.

Measure and Fit: Measure the shower tray to determine the length of the sealing strip required.

Add a Sealing Strip

Cut the Sealing Strip: Attach the top cover with an internal angle of 45 degrees. Slot both ends using a hacksaw to accommodate the inner corners.

Apply Sealant: Apply a generous amount of wallboard sealant in the lower channel of the sealing strip and lay a straight line of sealant on the shower tray.

Install Strips: Place the strips and fuse them together in the corners. Use adhesive to secure the inner corner trim to the wall.

Measure and Cut the Panel

Remove Protective Film: Remove the protective film from the panel surface and check for defects.

Measure and Cut: Carefully measure and mark the bathroom wall panels, then cut them to the correct height and width. Cut any necessary holes for pipes or showerheads.

Install the Panel

Position the Panel: Use a suction cup to position the panel, ensuring it is the correct size with a 3mm gap around the top edge and any cutouts.

Apply Sealant and Adhesive: Add sealant to the corner trim and fill the bottom sealing strip. Apply the bathroom wallboard adhesive directly to the panel in lines or zigzags.

Install Panels: Press the two panels fully into the sealing strip.

Remove Excess Sealant: Remove any excess sealant around the sealing strip and push the front strip and the end into place, ensuring the cover is flush.

Seal Fixtures: Seal any holes made for pipes or showerheads by applying sealant around fixtures.

Ready Your Shower Board

Allow the sealant and adhesive to set for 24 hours, and then your shower is ready to use!
