Installation Instructions

Pre-drill holes and attach with screws along the top back flange into the framing studs.
Make sure the two wall panels are in alignment and are level and plumb. Place level or
straight edge on both vertical flange where the wall will mate to the back wall and check
to assure there are no gaps. (For the 4836 four piece which has a single piece back wall
panel, skip this step).
23. If the water control valve is located on one of the side walls, it is important to dry trial fit
that panel first. Carefully measure and mark the location of the valve on the surface of the
side wall. Read the installation instructions provided by the valve manufacturer. Carefully
drill the valve hole(s).
Trial fit the side wall panel to the shower pan. Wipe clean the side ledge. This next step is a
two person job.
Lift the side wall panel and set it on the ledge. Set the panel so it is within one inch of the
vertical back wall seam. Make sure the pins in the pan index with the slots on the bottom
of the wall. Clear your fingers and slide the wall panel toward the back wall. Make sure the
alignment pins in the back wall index into the holes on the side wall. See Figure 24
When seated, the seam should have a minimal gap of 1/8" or less. If not, push the end of
the side panel until the vertical seam closes. See Figure 25 When in place, check the fit of
the valve hole. Adjust size and location if required.
When the fit is good, lift the wall panel away. Complete the valve installation and
connection to hot and cold water supply at this time. Also complete shower supply
connection. Strap pipes to framing if required. This is the last access to the plumbing before
the wall is permanently installed.
Clean the side ledge and apply a continuous 3/8" bead of100% RTV silicone caulking
along the entire length of the mating ledge of the shower pan. Apply the caulk completely
around each alignment pin.
Clean and apply a continuous 3/8" bead of 100% RTV silicone caulk along the entire length
of the vertical surface of the back wall where the side wall panel mates to the back wall.
Apply the caulk completely around each alignment pin. See Figure 23
