21. If all fits are good, proceed with the installation of the
the back wall. The installation procedures described in this
step apply for installation of one or two piece back walls.
Wipe clean the ledges on top of the pan. Apply a continuous
bead of 100% RTV silicone caulking along the back ledge of the
pan where the back wall will sit. The bead should be placed at
the middle of the ledge, and be 3/8” wide. The bead should go
completely around each alignment pin.
The lower section of the back wall is the panel with a single,
molded soap dish. Lift this panel up and carefully lower it onto the
back ledge on the pan.
There are slots on the underside of the wall. There are alignment
pins in the pan that will insert into the slots on the bottom of the
wall. See the detail in Figure 19.
Pre-drill the mounting flanges. Attach the wall with screws
through the back wall flange into the framing. Be sure the wall
panel remain level and plumb. (For the 4836 4 piece, this step
will apply for the entire back wall as one piece).
Push the wall panel down to seat it in the caulking.
Check the fit for level and plumb.
Note to installer: There is a difference having the bubble
between the lines and a plumb wall. The wall must be
VERY plumb or a gap larger than 1/8” will be present
where the side walls mate the back wall. Use wood shims
or furring strips to fill any space between the back wall
flange and the studs.
Align the wall section where it meets the shower pan so it is
centered on the pan, and install wood shims or furring strips
if necessary.

20. The next step will be to place the wall panels on the pan.
The back wall will be installed first. If the water control valve
is in the back wall, carefully measure and mark the location on
the surface of the wall panel. If installing in a shower with a two
piece back wall, the valve probably will be installed through the
lower wall panel. Make certain the valve does not conflict with
the mounting flange or seam. Read the installation instructions
provided by the valve manufacturer. Before the Trial fit, carefully
drill the valve hole (s) in the panel. When drilled,dry Trial fit the
back wall panel (s) on the shower pan to test the fit.
Confirm the gap where the wall seats to the pan is 1/8” or less.
Make sure the seam for the two piece wall is also 1/8” or less.
Adjust the valve hole size and location if required.
Lift the wall panel with the valve hole 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.
