Installation Instructions

ROUGH-IN PREPARATION
IMPORTANT: "ROUGH-IN" dimensions are provided for reference only! Measure actual Shower
Floor and check local building code requirements before constructing alcove.
NOTE: If using MUSTEE 700 Series Fiberglass Showerwalls, review instructions provided with
wall unit before framing alcove. (See detail shown below for typical installation.)
1. Refer to "ROUGH-IN" dimensions and determine location of Shower Floor.
2. Next, prepare SUB-FLOOR in Shower Floor area as follows:
Wood/Joist Floor:
Sub-floor must be min. 3/4" construction grade sheathing (CDX). Make sure
sub-floor is securely fastened to floor joists throughout alcove area with either
"Drywall"/Bugle Head screws (2-1/2" min.) or nails (rec. 8d Spiral Flooring Nails).
Make sure any "creaking or squeaks" have been eliminated by walking around
alcove area before proceeding.
Concrete/Cement Slab Floor:
Prepare surface in alcove area so that floor is level and sound.
3. Provide a 5" (inch) square opening in sub-floor or slab to accommodate Shower Floor drain body.
(Slab installation requires opening to be min. 2-1/4" deep). NOTE: If using a hole saw to cut floor
opening, you MUST use a 4-1/2" diameter (minimum) hole saw. Opening to be centered about
drain centerlines as specified in "ROUGH-IN" dimensions. Drain connection requires 2" (inch)
DWV pipe. Top of drain pipe must be even with top of sub-floor or slab.
4. Finally, we recommend that Shower Floor be installed on a bed of 30 lb. roofing felt or
equivalent to compensate for any inconsistencies in sub-floor or slab. (Gypsum cement or
panel/ floor adhesive could also be used for this purpose.)
SHOWER FLOOR INSTALLATION
5. Check Shower Floor carefully making sure it is not damaged.
6. Set Shower Floor into place. Level Shower Floor in both directions.
NOTE: Place level along top edge of tile flanges - do not use floor area which is tapered for
water drainage!
7. Shower w/Integral Drain Body
Apply a lubricant of some type (liquid soap works well) to the inside and outside of the Drain
Seal

prior to installation. Place Drain Seal over pipe and tamp into place using a hammer and -
1/4" (inch) dia. blunt rod or dowel. (Hint: 1/4" dia. bolt approx. 6" long works well as a tamping
tool.) Make sure top of Drain Seal is even with top of 2" (inch) waste pipe and in full compliance
with local code requirements pertaining to below floor waste connectors. (see Sectional View)
