Installation Instructions

4
A. One of the Side Panels will require drilling for the mixing/control valve handle(s). The showerhead
may be located through the Side Panel or above it (which ever you chose in your rough plumbing).
Double check
all measurements before you do any drilling. The drilling should be completed before
the unit is installed. Drill from the finished (inside) surface.
B. The Corner and Side Panels have a mounting flange that is designed to accept standard “drywall” screws.
The positioning of the studs and bracing have been laid out to give maximum support (horizontally and
vertically) behind these flanges. The mounting flanges have pre-marked holes. To avoid cracking the flange,
it is recommended that you pre-drill all of the holes with a 5/32” (inch) diameter drill bit. Countersink holes
for flush screw head fit.
C. To avoid any creaking or bowing that may take place with normal setting of the structure, it is mandatory
that every pre-marked mounting hole be utilized.
D. On the Corner Panel, you will notice a groove on the right and left side, going the full height of the
panel. We recommend that a bead of “clear” silicone sealant be applied into each groove. This will insure
a watertight seal when the Side Panel blades are inserted into these grooves. See drawing, Fig. E.
E. If a shower door (enclosure) is to be installed with this unit, we recommend bonding a piece of 1 x 3 to
the back side of each Side Panel prior to installation of the unit. If a curtain is to be used, the same 1 x 3
reinforcing strip should be used to “back-up” the mounting brackets. If unit has been installed and no
reinforcing strips have been used and you decide to mount either a shower door or curtain. You m
ust
use “Molly” type clinching anchors for all screws. See drawing Fig. F.
