2. Roughing-In Dimensions
IMPORTANT!
All dimensions are nominal. The stud opening tolerance is plus 1/4
″
(6 mm) and minus 0.
Carefully measure your fixture before determining enclosure size. When a fire rated wall is specified,
dimensions are to the inside of the wall board. Some shimming between the stud frame and the fixture
may be required. Dimensions given in the roughing-in information are crucial for proper installation.
Construct the framing and plumbing accurately.
NOTE:
If a firewall is required, roughing-in dimensions will have to increase according to the thickness of
the firewall material. Stud opening dimensions must be measured toward the exposed side of the wall
material.
NOTE:
If installing this unit to a masonry wall, make provisions for plumbing connections. Construct a
separate frame wall a minimum of 6
″
(15.2 cm) from the masonry wall.
3. Construct the Stud Framing
If you will be installing a shower door with this unit, refer to the shower door installation
instructions for any special framing considerations.
The apron of the receptor should be flush with the ends of the stud wall.
Provide double-stud support for the shower door wall jambs. Expanding wall anchors
will not
provide adequate support for the shower door assembly.
The double-stud wall-jamb supports must be square and plumb for proper shower door installation.
Construct 2x4 or 2x6 stud framing for one side and back wall according to the roughing-in
information.
If grab bars are to be installed,
provide 2x6 bridging or attachment at specified positions. Refer to
the grab bar manufacturer’s instructions.
The basin area requires no additional support when the subfloor is plumb and level with respect to
the stud framing. If the subfloor is not level, shimming may be required to level the unit.
