Instructions / Assembly

SI-199 (5•06) SI-199 (5•06)
The size and style of drain must be determined before installation of the ShowerTub™ can begin. Both 2” Drain
Assemblies require a 5” (inch) square hole in the sub-floor or slab, centered around the sanitary waste pipe.
The drain body for either PN 42.317A or PN 42.304A must be assembled to the ShowerTub™ before installing
into the alcove (the drain body is secured with a locknut on the underside of the floor area.) Be sure to use all
washers that are supplied with the drain assembly, refer to “TYPICAL DRAIN CONNECTION” for reference.
The MUSTEE ShowerTub™ 1-1/2” Drain Kit may be installed after placement into the alcove area (with access
to the underside of the unit). Complete installation instructions are furnished with kit.
NEW CONSTRUCTION
The ShowerTub™ must not be installed on exposed floor joists, if there is no sub-floor at the desired
location, a one piece section of CDX sheathing - minimum 3/4” thick, must be securely fastened to the floor
joists so that the ShowerTub™ is fully supported. HINT: To reduce creaking or squeaks we suggest that
“deck” type screws (3” min. length) along with adhesive be used to secure the sub-floor to the floor joists.
REMODELING
Remove existing bathtub from alcove, inspect condition of sub-floor for damage, if necessary, replace
existing sub-floor with CDX sheathing as described under NEW CONSTRUCTION.
A. For either NEW CONSTRUCTION or REMODELING, while a mortar bed is not required for structural
support, a thin layer will aid in the leveling of the ShowerTub™ and help ensure that all ribs are fully
supported.
B. If you choose not to use mortar, a layer of 30 lb. roofing felt (or equivalent) should be used to compensate
for any minor inconsistencies in the sub-floor or slab.
C. Set ShowerTub™ into alcove, making sure that it is properly level. Check level on to edge of tile flange only
- all other surfaces are tapered.
D. Make final drain and supply connections as previously determined.
TYPICAL DRAIN CONNECTION
CAUTION: DO NOT USE ANY PUTTY OR THREAD SEALING COMPOUND UNDER FLANGE OR ON
THREADS OF DRAIN BODY - FAILURE AND LEAKAGE MAY RESULT!! DO NOT OVERTIGHTEN LOCKNUT -
HAND TIGHTEN, THEN WRENCH AN ADDITIONAL 3/4 TURN - MAXIMUM.
To use the MUSTEE MODEL NO. 3060 ShowerTub™ with existing 1-1/2” plumbing, we have designed an
adaptor that will reduce the standard drain hole outlet to accept Part No. 60.300 “ShowerTub™ Drain Kit”.
Proceed as follows:
1. Stand and secure the ShowerTub™ on end with drain hole up - this will make installation of the Drain
Adaptor - PN 60.306 easier.
2. Apply a small bead (approximately 1/8” diameter) of siliconized sealant (not furnished) to the underside of
the drain adaptor top flange, as shown in (FIG. 1).
3. Insert adaptor into drain hole, holding adaptor from moving (from the underside of the Showertub™) first
apply the 1/8” Sealing Washer - PN 42.319 followed by the Friction Washer - PN 32.207 and secure in place
with Locknut - PN 42.305.
4. DO NOT overtighten locknut - pull up snug then wrench an additional 1/4 turn. Wipe away any excess
sealant that seeps out around the top flange of the adaptor on the inside of the ShowerTub™.
5. Attach Part No. 60.300 ShowerTub™ Drain Kit to complete installation.
