Install the Wall Panels
The first wall panel includes the corner piece and extends to the right (Image 1). Take extra care to level and position this panel correctly because it will affect the position of the rest of the shower components.
Use 1-1/2" galvanized roofing nails to fasten the first wall panel through slots provided on the panel flange.
Measure the location of the showerhead pipe and valve (Image 2).
Then transfer the dimensions to the second wall panel (Image 3). Accuracy is essential.
Bore holes for the plumbing outlets in the second wall panel (Image 4). Use a 3/4" Forstner bit for the shower pipe hole. If required, larger holes for the shower handles can be drilled with a hole saw or expanding bit. Place scrap wood blocking under the panel to prevent the drill bit from breaking through and cracking the plastic.
After the holes are drilled, position the second wall in place. This section slides into place and connects with molded plastic fittings (Image 5). Secure it to the wall studs with nails through the nailing flange, as on the first panel.
