(5 mm x 5 mm) v-notched
trowel or 1/8" x 1/8"
(3 mm x 3 mm) square or

subfloor at desired drain
location. Using the removable
subfloor cutout template on
the shower tray disk, trace
the hole location on the
subfloor before cutting.

Note: Alignment of drain grate

to tile layout must be established
before cutting the hole in the
subfloor.

Tip: Dry-lay the pre-sloped

shower tray, then align the shower
tray disk with the clock marks on
the tray to the desired position
before marking and cutting the
hole in the subfloor.

2. Apply unmodified thin-set
mortar to the subfloor
using a 1/4" x 3/8"

fully embedding in the thin­set mortar and positioning to
match drain hole orientation
using the clock marks on the
shower tray.

flange. Once in place apply
unmodified thin-set mortar
to the top of the bonding
flange. Do not fill the recessed
areas of the bonding flange
with thin-set mortar until the
grate assembly is ready to be
installed.

Note: If there is no access to

the waste line from below, the
Durock Drain Assembly must be
connected to the waste line at the
same time it is pressed into the
mortar.

10. Embed Dur oc k Shower
System Waterproofing

mortar using a finishing
trowel, drywall taping knife,
or similar tool to remove air
pockets and ensure proper

Tip: Before applying mortar to

shower tray and shower tray
disk, establish the location of the
hole in the shower membrane
that corresponds to the recessed

by first dry-fitting the drain body
and membrane. Cut the opening
