Prepare the bathroom

Prepare the area where you want to install the shower wall panel. Make sure that the wall is clean, degreased, and free of dirt and dust.

Next, check that the wall is flat and perpendicular to the level.

Make sure the fixing method is in place

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

Wooden slats of uniform thickness of approximately 25 mm x 50 mm should be fixed vertically in the center of 585 mm, using 585 mm panels. Ensure that all vertical panel joints are properly supported by vertical slats, and their spacing should be determined to suit the specific panel width you are installing.

All slats must be installed vertically and parallel and packing gaskets are used to ensure that all slats are completely vertical and their surfaces are level. Additional slats should be placed to carry heavy objects, such as washbasins, wall-mounted toilets, or furniture. The corners should also use vertical slats to support the corner contours.

Install the shower tray

It is very important to use a spirit level to check and make sure that the shower tray is also in a horizontal position.

Measure the shower tray to determine the length of the sealing strip required. Note: make sure the shower screen fits you

Add a sealing strip

Cut the sealing strip and attach the top cover so that it has an internal angle of 45 degrees. Then slot at both ends and use a hacksaw to accommodate the inner corners. Make sure that there are notches on both ends of the trim.

Check that the notches on the corners match, and use a pencil to make a mark on the shower tray.

Apply enough wallboard sealant in the lower channel of the sealing strip. Make sure that the cavity is completely filled with sealant.

Lay a straight line of sealant on the shower tray you marked earlier. Put down the strips and fuse them together in the corners. Next, use adhesive to secure the inner corner trim to the wall.

Now that your main structure is in place, please measure the height and width of the bathroom wall panels.

Cut the panel to a suitable size

At this time, remove the protective film on the surface of the panel and check for defects or problems.

Check your measurements carefully, then mark the bathroom wall panels and cut them to the correct height and width. At this point, you also need to cut any holes for the pipe or showerhead.

Install the panel

Using a suction cup, place the panel in place to ensure it is the correct size, and confirm that there is a 3 mm gap around the top edge of the panel and any cutouts.

Add a large amount of sealant to the corner trim and fill the bottom sealing strip. Use lines or zigzags to add the bathroom wallboard adhesive directly to the panel.

Install the two panels, making sure they are fully pressed into the sealing strip.

Remove the excess sealant around the sealing strip, then push the front strip and the end into place, making sure that the cover is now completely flush.

Seal any holes you previously made for pipes or showerheads by applying sealant around fixtures and fittings.

Your shower board is now ready

Leave the sealant and adhesive for 24 hours to ensure that they are completely set, and then your shower is ready to use!
