Installation Guide

3. Place up to a 1/2” thick layer of mortar/thinset on the
floor. This will ensure complete contact and support
by the existing subfloor, eliminating shower floor flex
during normal use. Taper the mortar/thinset to 1/4”
thick around the floor drain. Mix enough material to
cover the area under the shower floor. Do not place
the material closer than 2” to the edge of the shower
floor or the drain opening.
4. With the stainless steel clips installed on the
threshold, place the barrier-free shower floor into the
framework and firmly press it into the mortar/thinset.
The outer perimeter of the shower floor should
contact the subfloor.
Note: Make sure the side and back flanges of the
shower floor are parallel with the framework, with an
even gap (recommended 3/16”) between the framework
and the shower floor flanges.
Do Not Use Nails
To prevent damage to the shower floor and
possible water or other damage to floors, pipes,
walls, or other portions of your building or
home, do not nail or screw through the shower floor to
secure it to the framework. Nails are not necessary to
hold the shower floor in place, but if nails are used they
must be installed above the shower flange and not
through it. Refer to the specific instructions in this manual
for the proper installation of these optional nails.
5. Level the barrier-free shower floor in both directions,
and allow the mortar/thinset to cure for 24 hours.
Once cured, the mortar/thinset will prevent the
shower floor from moving without the use of any
mechanical fasteners.
Note: For optional, but not required, fastening of the
shower floor to the framework by toe-nailing, refer to the
Optional Shower Floor Toe-nailing Procedure section in
this manual.
