Installation Sheet

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.
If the floor is not level and flat, the shower floor must be
set in a bed of mortar to provide adequate support, as
described in Step 2. Install the shower floor using a
mortar mixture or an equivalent material, such as
thinset. If the floor is perfectly level and flat, you may
proceed directly to Step 1 below.
1. Place the shower floor into the rough opening.
Level the shower floor in both directions. All support
ribs and the front edge of the shower base must
make firm contact with the subfloor. If any part of
the shower floor is not completely supported,
proceed to Step 2; if it is fully supported, proceed to
Step 5.
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.
Note: Optional, but not required, fasten the shower floor
to the framework by toe-nailing above the floor flange,
refer to the Optional Shower Floor Toe-nailing Procedure
section in this manual. Do not drive nails through any
part of the shower base, as stated below.
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.
Note: The ideal installation results when the outside
surface of the wall board and shower floor flange are
flush, as shown in the illustration below.
This dimension
allows the DreamLine wall panels or alternate shower
wall material, to rest against the lip of the shower floor
once the moisture-resistant wall board is installed, as
shown in the second illustration below.
Note: Steps 2-4 must be used for uneven floors that
do not provide complete support under the base.
2. Place up to a 1/2” thick slurry of fast-drying cement
or mortar 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.
