ROUGH-IN FRAMING-NEW CONSTRUCTION
NOTE: THIS DRAWING REFERS TO INSTALLING MUSTEE/PN 42.317A DRAIN ASSEMBLY
DRAIN ASSEMBL
Y IS NOT FURNISHED - SEE "AVAILABLE DRAIN ASSEMBLYS" BACK COVER
After you have determined where your Mustee "BARRIER-FREE" Shower Floor will be located, you
will have to construct the appropriate alcove. Be sure to plan your "rough" plumbing requirements
(drain-venting-supply lines) at this time. Also any additional bracing or reinforcement for support
handrails or seats. Refer to "Rough-in Framing" illustration for suggested plan, although each
installation will vary as determined by individual requirements. Measure actual Shower Floor before
constructing alcove.
With alcove constructed and the "rough" plumbing requirements completed, you are now ready to
install the Mustee "BARRIER-FREE" Shower Floor.
RETROFIT-BATHTUB REPLACEMENT
Remove original bathtub, remove and replace "bathtub" style control/diverter valve with "shower
stall" type. Inspect sub-floor for water damage and replace if necessary. Follow steps, 1 through 6.

SHOWER FLOOR INSTALLATION
FIG. 1.
1. The Shower Floor m
ust not be installed on exposed floor joists, if there is no sub-floor at the
desired location, a one-piece section of sheating (CDX) the same thickness as the surrounding sub-
floor must be securely fastened in position, so that the Shower Floor is fully supported.
HINT: To reduce "creaking or squeaks" we suggest that deck type screws (3" min. Iength) along with
adhesive, be used to secure the sub-floor to the joists-especially under the Shower Floor and Entry
Ramp (if so equipped). Fig. 1.
2. As specified in the "ROUGH-IN FRAMING" illustration, a 5" (inch) square opening in the sub-floor
or slab will be required, located on the center line of the Shower Floor-8 1/2" from either right or left
side. Drain connection requires 2" (inch) DWV waste pipe--Note: top of waste pipe must be level with
top of sub-flooring.
