Thank You For Choosing Sterling

contact us. Our phone numbers are listed within this manual. Thanks again for choosing Sterling.
Tools and Materials
Before You Begin
CAUTION: Risk of product damage. Install the whirlpool on an adequately supported, level
subfloor. The basin area requires no additional support when the subfloor is level and square with
the stud framing. Use shims for additional support if the subfloor is uneven. Do not install the
whirlpool over open floor joists.
CAUTION: Risk of property damage. Only apply 100% silicone sealant to the areas where
instructed to do so. Do not add silicone sealant to any other areas. The inappropriate use of silicone
sealant may trap moisture and could result in mold, leakage, or mildew. For whirlpool-only
installations, 100% silicone sealant is required at the seams of the walls and the whirlpool. We
recommend using colored 100% silicone sealant to match the color of the product. Use of latex
based or other caulks is not recommended. If a shower door will be added, you will be instructed
to apply silicone sealant where the front edges of the end wall surrounds will meet the whirlpool.
This will prevent water from passing through the shower door extrusion to the back side of the
wall. Follow the shower door and silicone sealant manufacturer’s instructions.
CAUTION: Risk of product damage. Do not lift the whirlpool using the apron brace. Lift the
whirlpool by the rim at multiple points. Whirlpool units in a single carton are shipped with apron
braces in the closed position. Whirlpool units in multi-pack cartons are shipped with one or more
sets of apron braces disconnected at the apron. Connect the apron braces to the apron before
removing the unit from the carton(s).
IMPORTANT! If your whirlpool is shipped with a liner, keep the liner in place until construction is
complete to prevent surface damage to the unit. If a liner is not available, place a clean drop cloth or
similar material in the bottom of the whirlpool.
IMPORTANT! Risk of product damage. Do not install the whirlpool over open floor joists. The basin area
requires no additional support when the subfloor is level and square with the stud framing. Install the
whirlpool on an adequately supported, level subfloor. Use shims for additional support if the subfloor is
uneven.
Read all instructions before you begin.
Observe all applicable plumbing, electrical, and building codes.

Roughing-In
IMPORTANT! All dimensions are nominal. The stud opening tolerance is +1/8″(3 mm)/-0. Carefully
measure your fixture before determining enclosure size. Some shimming between the stud frame and the
fixture may be required. 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. Dimensions given in the roughing-in information are crucial for proper
installation. Construct the framing and plumbing accurately.
1. New Framing Construction
NOTE: Refer to the ″Roughing-In″section for dimensions.
WARNING: Risk of product and property damage. The whirlpool must be supported by the
subfloor.
Framing Provisions
A subfloor must be installed. The whirlpool must be positioned to allow clearance for drainage
through the floor joists or slab and to allow convenient plumbing installation.
IMPORTANT! Accessories that require backing or support are not recommended for this installation.
Installing these accessories could void the warranty.
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.
IMPORTANT! Construct the floor of plywood. If whirlpool is installed over material other than plywood,
friction may cause squeaking over time.

2. Prepare the Site
IMPORTANT! The whirlpool supports must rest directly on a level subfloor.
IMPORTANT! Squeaking may develop if the whirlpool is installed over a subfloor other than plywood. In
order to prevent squeaking, place the included pad between the whirlpool and the subfloor and positioned
under the whirlpool supports. Do not use roofing felt.
IMPORTANT! The drain line must be installed in accordance with the drain manufacturer’s instructions.
Locate the drain line and trap using the dimensions given in the ″Roughing-In″section.
For through-the-floor drain installations, cut the hole in the floor for the drain assembly. The drain
connection should be made directly under the overflow drain. Leave room to connect the piping.
Verify the subfloor is level. If the subfloor is not level, proceed to the ″Level the Subfloor″subsection
below.
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.
Carefully measure your fixture before determining enclosure size. Some shimming between the stud frame
and the fixture may be required. Dimensions given in the Roughing-In section are crucial for proper
installation. Construct the framing and plumbing accurately.
Level the Subfloor (Optional)
IMPORTANT! The whirlpool may also be leveled using shims.
IMPORTANT! Mortar cement is required to level an uneven subfloor. Do not use plaster, gypsum cement,
or drywall compound for this application, as these materials do not provide adequate structural support.
Spread a layer of mortar cement on the subfloor where the whirlpool supports will be located.
Route the electrical supply to the future outlet location.

3. Install the Rough Plumbing
NOTE: Provide access to all plumbing connections to simplify future maintenance. Include access at the
back of the plumbing wall whenever possible.
Install the water supply pipes according to the faucet manufacturer’s instructions. Cap the supplies
and check for leaks.
Strap the supply lines to the stud framing.
Install the shower valving according to the manufacturer’s instructions. Do not install the trim at
this time.

4. Remove the Apron Panel
Insert a flat-blade screwdriver or other prying tool into one of the two screwdriver slots.
Use the screwdriver to pry the bottom clip out and release the clip.
When all bottom clips are released, pull the bottom of the panel away from the apron to release the
remaining clips.
When the bottom of the panel is clear, lower the panel until the top of the panel is clear.
Store the panel in a safe place.

5. Position the Whirlpool
CAUTION: Risk of product damage. Do not lift or move the whirlpool by the apron or apron braces.
Verify that the apron braces are attached before installing the whirlpool, then lift the whirlpool by the rim
at multiple points.
NOTE: If the whirlpool cannot be directly bonded to the subfloor or if decreased movement is desired,
consider installing an optional mortar cement bed following the ″Install a Mortar Cement Bed″steps
below.
NOTE: Keep a liner or drop cloth in place in the bottom of the whirlpool until construction is complete.
Dry fit the whirlpool.
Check the whirlpool to make sure it is level.
If the bath is not level, level using mortar cement following the ″Install a Mortar Cement Bed″steps
below, or shim with metal, hardwood, or other durable material. Reposition and shim the bath until
it is aligned with the framing and level.
Mark the height of the whirlpool flange on each walled side.
Remove the whirlpool.
Measure down 11/16″(1.7 cm) from the first mark and make a second mark.
At the second mark, install a brace, a maximum of 54″(137.2 cm) long and 1-1/2″(3.8 cm) thick, for
rim support.
Dry fit the whirlpool and make sure the rim of the whirlpool does not support its weight. Lower
the brace slightly if the weight of the whirlpool rests on the brace.
Remove the whirlpool.
Install the drain and overflow assembly to the whirlpool according to the drain manufacturer’s
instructions.
IMPORTANT! Squeaking may develop if the whirlpool is installed over a subfloor other than plywood. In
order to prevent squeaking, place the included pad between the whirlpool and the subfloor and positioned
under the whirlpool supports. Do not use roofing felt.
Position the pad under the whirlpool supports.
Position and adjust the whirlpool until its outside edge is flush with the framing.
Verify that the whirlpool is level and well supported by the subfloor.
