UNDERMOUNT
BATHTUB
INSTALLATION GUIDE
3
Do not build the surrounding structure before receiving your unit. Structure measurements should be verified
against the unit to ensure a proper fit.
Make sure you install all plumbing and drainage before securing the unit. It is always recommended to have a
competent, professional plumber do the plumbing installations.
Before drilling a hole in the floor for the drainpipe, make sure there are no hidden elements underneath (pipes, floor
joists, heating ducts, electrical wires, etc).
The unit must be installed perfectly levelled. Level the unit using wood edges fixed to the floor under the wooden
base or using mortar cement. All the legs must be in contact with the floor. If the leveling does not permit it, it is
imperative to add a wood edge to support the bath or the shower.
To provide additional support, improve soundproofing and facilitate leveling, it is recommended that a layer of
mortar or plaster be applied to the base of the bathtub legs, and covered with a 1/16” (2 mm) polyethylene sheet.
The layer should be thick enough to facilitate the leveling of the unit without raising it. Once the unit is in position,
ensure it is level in both directions for proper draining.
Leveling must be done under the wood legs located beneath the unit. Do not level directly behind or under the
flange at the front of the unit.
