6. Position the Whirlpool
NOTE: Keep a liner or drop cloth in place in the bottom of the whirlpool until construction is complete.
Install the drain and overflow assembly to the whirlpool according to the drain manufacturer's
instructions.
IMPORTANT! Squeaking may develop between the bath and the subfloor. If your bath was shipped with
a pad, place the pad between the bath and the subfloor. If your bath was not shipped with a pad, we
recommend installing it in a bed of mortar cement. See "Install a Mortar Cement Bed" section. Do not use
roofing felt or polyester materials.
IMPORTANT! Do not remove the clips that are attached to the whirlpool. The clips are required to ensure
proper installation of the walls.
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.
If the whirlpool is not level, shim using metal, hardwood, or other durable material. Reposition and
shim the whirlpool until it is aligned with the framing and level.
If decreased movement is desired, consider installing an optional mortar cement bed.
Install a Mortar Cement Bed (Optional)
Remove the whirlpool and pad from the alcove.
NOTE: Do not use plaster, gypsum cement, or drywall compound for this application, as they will not
provide adequate structural support.
NOTE: The whirlpool supports must rest directly on the subfloor.
Spread a 2" (51 mm) layer of mortar cement on the subfloor, spreading it so that each area of the
whirlpool that will contact the subfloor has mortar cement. Do not spread the mortar cement
around the drain area. Allow room for the mortar cement to expand from the weight of the
whirlpool.
Immediately move the whirlpool into position.
Verify that the whirlpool is level and resting on all supports.
Clean the whirlpool to reduce the risk of damaging the surface.
Place a clean drop cloth or other similar material into the bottom and over the outside edge of the
whirlpool. Be careful not to scratch the surface of the unit.
