And be sure to make moisture and waterproof treatments on the base wall in advance. And compared to strips, it is recommended to use full sheets, because it would be easier to fit the SPC wall panel, and you can hang accessories anywhere.

Please note, you need to enhance the back wall when installing heavy accessories or furniture.

Question 5: what are the requirements for the back wall?

Plumb, flat and straight.

Make sure the back wall is level: Horizontal deviation ≤ 2mm/m2, Vertical deviation ≤ 2mm/m2, and the corners are straight 90°.

Question 6: what to do if fail to meet the requirements?

To make a bowed or bent back wall plumb and even is to plane out or shim the faces of studs that are recessed behind the plane of the other studs.

Trust me, a plumb wall will come back a hundred times when installing wall panels.

Question 7: which one goes first, SPC wall panels, tray or bathtub?

In order to prevent any water leakage under the shower tray or tub, you should first install the shower tray or bathtub first and then set the shower SPC wall panels onto it. Also don’t forget to put waterproof silicone adhesive at the joint bottom.

Question 8: why need to make sure the base is level?

Because you need to make sure the top and bottom are lined up, especially for the shower SPC wall panel installation.

Question 9: what if your wall is taller than the SPC wall panel?

The height in our standard SPC wall panel collection ranges from 2m to 2.8m to meet the demands of most spaces, but if you still need to panel a taller wall, then you will need to use the H-joint trim to connect between the short edges of wall panels.

And also don’t forget to use the H-joint trim for expansion when the continuing length of the wall panels is longer than 10m.
