22. For 5 piece units, the next step is to place the top section of
the back wall. Clean the back ledge and apply a continuous
bead of 100% RTV silicone caulking along the ledge of the back
wall where the top part of the wall will sit. The bead should be
3/8 wide and placed at the middle of the ledge. It should go
completely around each alignment pin.
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).
23. Side wall installation. The side wall panels are slotted on the
bottom. The alignment pins in the pan will index with these
slots. The slots will allow the side wall panel to slide about one
inch to meet the back wall panel.
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)
Lift the top back wall panel and set it on top of the lower wall.
Press the panel down to seat in the caulking. The top and
bottom wall panels must be level and plumb. Shim if necessary.
The seam between the panels should be no more than 1/8”.
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 4 piece
which has a single piece back wall panel, skip this step).

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.
Clean the side ledge and apply a continuous 3/8” bead of
100% RTV silicone caulking along the entire length of the
mating ledge of the shower pan. Apply the caulk completely
around each alignment pin.
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.
