ROUGH-IN FRAMING
Refer to Fig. A & B for recommended alcove framing. If framing is pre-existing and you choose
not to re-frame, you MUST make sure existing stud placement will not interfere with mounting
clips. Be sure to plan your rough plumbing requirements (drain-venting-supply lines) at this time.
HINT: You may want to install Kraft Faced fiberglass insulation or unfaced batting with a 4 mil.
(poly) vapor barrier film between the open studs of your alcove area.
After you have prepared your alcove
and completed your rough plumbing
requirements, proceed with installation
of bathtub (if applicable) per tub
manufacturer’s instructions.

Please review the following steps (A thru E) before beginning the permanent Model 660
Bathtub Wall installation.
A. One of the Side Panels will require drilling for the mixing/control valve handle(s), tub spout
& showerhead (if applicable). The showerhead may be located through the Side Panel or
above it (whichever 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.
IMPORTANT: Be sure to take into account the Center
Panel wrap around when laying out hole locations (see Fig. D).

B. The Center and Side Panels have a mounting flange that is
designed to accept standard “drywall” screws. The positioning
of the studs and bracing (see ROUGH-IN FRAMING) 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, Fig. H.
C.
To avoid any creaking or bowing that may take place with
normal settling of the structure, every pre-marked hole
should be utilized.
D. If a bathtub door (enclosure) is to be installed with this unit,
we recommend bonding plywood strips to the backside of each
Side Panel prior to installation of the unit. If a curtain is to be
used, the same plywood strips should be used to “back-up”
the mounting brackets (Fig. H). If unit has been installed and
no reinforcing strips have been used and you decide to mount
either a shower door or curtain - You MUST use “Molly”-type
clinching anchors for all screws. See drawing, Fig. D.
E. If installing ADA grab bars, you MUST reinforce panels by
bonding strips of wood/plywood to back side of panels as
shown in Fig. D.

1. ATTACH MOUNTING CLIPS…
a) Position clips on molded lugs located near
bottom of Center Panel with clips pointing
“down” as shown in drawing (Fig. E).
b) Secure the clips using the two (2) #12 x 5/8”
screws provided.
CAUTION: Do not over-tighten screws! Use a
standard #2 Phillips screwdriver.
2. Attach REINFORCING STRIPS* (optional for standard installation)
a) Bond a piece of 1 x 4 to backside of Center Panel as shown to reinforce ADA Grab Bar (Fig. D).
*NOTE: Grab Bars must be secured THROUGH REINFORCING STRIPS and into stud or wall plate!
SIDE PANEL PREPARATION
1. Attach door/curtain rod REINFORCING STRIPS
a) Bond1/2” thick plywood strips to backside of both Side Panels to reinforce door/curtain rod.
Be sure to allow clearance at bottom of panels for bathtub flange (Fig. D & Fig. H).
2. Attach REINFORCING STRIPS* (optional for standard installation)
a) Bond 1/2” thick plywood strips to backside of Side Panels as shown to reinforce ADA Grab
Bars (Fig. D).
*NOTE: Grab Bars must be secured THROUGH REINFORCING STRIPS and into stud or wall plate!
You are now ready to proceed with the
permanent installation of your bathtub wall unit.
BATHTUB WALL INSTALLATION
Trial fit the Center Panel and both right and left
Side Panels in place before applying any
adhesive or mounting screws. Be sure to check
alignment of the front edges of the Side Panels
with the front surface of the bathtub threshold
as shown in drawing, Fig. G.
If any gap is present between backside of
mounting flange and face of stud, a tapered
piece of wood (shim) may be used to fill the
gap. Install “deck” screws through shims
during permanent installation.
Now that the Center and both Side Panels
are aligned horizontally, level and vertically
plumb in alcove, using two of the previously
drilled 5/32” dia. holes in each panel as a guide,
