Installation Guide
B.  For each hole to be cut, measure the vertical distance 
between the center of the plumbing xture and the shower 
base. Measure the horizontal distance between the center of 
the xture and the installed back wall panel. Mark the center 
of the xtures on the face of the panel.
C.  Using a drill, make a small pilot hole in marked locations. 
Using a jigsaw, hole saw, or paddle bit cut out each hole in 
the panel to the appropriate size for the particular pipe or 
xture. Make each hole only as large as necessary for access 
to the plumbing. Cover plates only cover so much!
D.  With holes drilled so the panel now ts over the plumbing, 
you can ne tune the t of the panel into the back corner and 
against the shower base from step 3.A.
E.  Prior to adhering the plumbing wall panel, seal the back 
panel A to the corner reinforcement using a small bead of 
Performance Pro 100% Silicone.
F.  Follow Step 2.B and adhere the side panel, but also form 
a bead of adhesive on the back around each plumbing hole.

3.  Installation of Wet/Plumbing Wall Panel (B)
A .  Hold side panel as close to plumbing wall as possible. 
Scribe and trim the inside edge and bottom edge against 
the shower base for best t before measuring, marking, 
and cutting holes for plumbing xtures. The depth of 
the side wall panels can also be trimmed down to t the 
opening or your shower base, although how you decide to 
install vertical trims C and E will inuence the width sizing 
of side wall panels (see Section 4.) 
NOTE: You will be able to ne tune your panel to a more accurate 
t after the holes are cut and your panel can be rmly pushed into 
the corner.
4.  Installation of Opposite Side Wall Panel (B)
A .  Use same procedures as in steps 3.A-3.F except that 
no holes will be drilled in this panel. Dry t rst, and then 
apply silicone to seal the corner, and adhesive as you did 
on previous side panel.
