Installation Guide

Standard Shower Floor Installation
These instructions cover the installation of any square,
rectangular, or neo-angle shower floor. The shower floor
is designed to be installed directly on the subfloor and
should rest loosely against the stud wall framework
maintaining the recommended 3/16” gap.
Note: Barrier-free shower floor and ramp installation
instructions are provided in a separate section in this
manual.
The shower floor must be set in a bed of mortar to
properly hold it in place. Install the shower floor using a
mortar mixture or an equivalent material, such as
thinset.
1. Place up to a 1/2” thick layer of mortar/thinset on the
floor. Mix enough material to cover the area under
the shower 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.
Do not place the material closer than 2” to the edge
of the shower floor or the floor drain opening.
2. Place the shower floor into the rough opening and
firmly press it into the mortar/thinset. The exposed
front bottom edge(s) 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.
3. Level the 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.
