INSTALLATION
Apply unmodified thin-set mortar to the
substrate using a 1/4" x 3/8" (6 mm x 10 mm)
square- or U-notched trowel.
1
Place the KERDI-SHOWER-ST tray and
solidly embed in the mortar. Check the
underside of the tray to ensure full coverage
and support are achieved.
2
Completely fill the step in the shower tray
with thin-set mortar. Press KERDI-DRAIN
firmly into the mortar to ensure full support
of the bonding flange.

-KERDI-SHOWER-ST prefabricated shower tray
The substrate must be clean, even, and load bearing. Any leveling must be done prior to shower tray installation. If necessary, cut the tray to size prior
to application; ideally, the tray is cut equally on all sides to ensure a consistent perimeter height. The base can also be extended beyond the tray using
dry-pack mortar.
Plumbing Access: If there is access to the plumbing from below and the waste line can be connected after installing KERDI-DRAIN, the tray can be installed
prior to the drain.
Preparation
Locate and cut a hole in the substrate for the drain outlet and coupling to the waste line using the template provided. Limit the diameter of the hole to
5" (125 mm) maximum to ensure proper support for the tile assembly. Note: Fill in box-outs in concrete floors with dry-pack mortar or concrete. A pipe
coupling or similar can be used as a form around the waste line.
Begin by dry-fitting the components.
Measure and cut a section of pipe to connect
KERDI-DRAIN to the odor trap using the
detachable center section of the tray or
foam spacers included with the drain as a
spacer. Prepare the odor trap, pipe, and
KERDI-DRAIN with cleaner, primer and ABS
or PVC cement per the solvent cement
manufacturer’s instructions and connect.
1
Apply thin-set mortar to the substrate and to
the top and bottom of the detached center
section of the KERDI-SHOWER-ST tray.
Slide the center section into place below the
drain to ensure solid and uniform support of
the bonding flange.
2
Apply unmodified thin-set mortar to the
substrate using a 1/4" x 3/8" (6 mm x 10 mm)
square- or U-notched trowel. Place the
KERDI-SHOWER-ST tray and solidly embed
in the mortar. Check the underside of the
tray to ensure full coverage and support are
achieved.

No Plumbing Access: When there is no access to the plumbing from below, KERDI-DRAIN is installed to the appropriate height and connected to the
waste line prior to the installation of the shower tray.
