Prepare the Site (Framing Construction) (cont.)
If a firewall is required, roughing-in clearances must increase according to the thickness of the
firewall material. Stud opening dimensions must be measured toward the exposed side of the wall
material.
When units with wall surrounds are installed over drywall, plaster, or other water-resistant wall
material, the nailing-in flanges should be covered with finish molding.
An access panel should be installed at the drain end of the bath. This access panel is not shown.
If installing this unit with a shower door, refer to the shower door manufacturer's instructions for
any special framing considerations. It may be appropriate to add studs for pivot shower door
support.
If installing a unit with wall surrounds to a masonry wall, make provisions for plumbing
connections. For the plumbing end wall, construct a separate frame wall a minimum of 6" (15.2 cm)
from the masonry wall. For the other walls, use 2x2 furring strips to provide stud locations.
If installing a bath-only unit to a masonry wall, make provisions for plumbing connections and
finish wall installation. A 2x2 furring strip around the inside edge of the bath may be used to secure
the bath in place. Locate the furring strip at the height needed for the attachment clips or roofing
nails, whichever will be used.
2. Framing Construction
The bath with apron must be attached to the walls on three sides. Attach the bath with the supplied
attachment clips or with large-head roofing nails. The attachment clips or nails limit the freedom of
movement for the sides and ends of the bath. The wall attachment is not intended to be load bearing.
Subflooring must be installed. The bath must be positioned to allow clearance for drainage through the floor
joists or slab and to allow convenient plumbing installation. Studs must be positioned roughly as shown for
the attachment of clips or the fastening of the nailing-in-flange. Other stud locations are optional except that
the stud location must meet the load-bearing requirements of local building codes. Studs must also allow for
the installation of the plumbing fixtures and any shower door. Locate the shower door studs as required by
the shower door manufacturer.
Install the Framing
NOTE: Refer to the Roughing-In section for dimensions.
For installations with wall surrounds, ensure that the outer stud is positioned for the vertical
nailing-in wall flanges at 31-1/2" (80 cm) from the back wall. The outer edge of the stud should
align with the edge of the flange.
For a bath only installation, ensure that the outer stud is positioned for the apron flanges at 31-1/2"
(80 cm) from the back wall. The outer edge of the stud should align with the edge of the flange.
If the apron nailing-in flanges are not going to be used or have broken off, install three evenly
distributed 2x4 blocks just behind the apron location. These will prevent the apron from being
damaged and may be used to secure the apron behind a baseboard. Measure the bath for the
required clearance behind the apron and for the location of the blocks.
Construct 2x4 stud framing for your particular installation according to the Roughing-In section.
For an installations using a shower door, refer to the shower door manufacturer's instructions for
any special framing considerations.
Ensure that the framing for each stud is plumb and square to within 1/8" (3 mm). Shimming will be
required if tolerances are not met.
If possible, construct an access panel in the end wall to allow clearance for servicing the faucets and
drain.
