Installation Guide

The KERDI collar on KERDI-LINE-VARIO is
integrated with the adjoining waterproofing
assembly using Schluter SET
®
, ALL-SET
®
,
FAST-SET
®
, or unmodified thin-set mortar.
The KERDI collar must be cut and folded
where the KERDI-LINE-VARIO is installed at
a wall corner and may require trimming to
avoid excess build up over the tray recess
lip.
Begin by dry-fitting the components; make
any necessary modifications to the existing
plumbing. Apply the thin-set mortar or
KERDI-FIX underneath the foam support.
Prepare the adjoining pipe and KERDI-LINE-
VARIO per the manufacturer’s instructions
and connect when installing the flange in
Step 7.

or unmodified thin-set mortar, centered over
the joint. Install KERDI-KERECK at all inside
and outside corners.
Note: A flood test is strongly recommended
before setting tile to verify a successful
installation. Wait a minimum of 24 hours
after the membrane installation is complete
to allow for final set of thin-set mortar and
ensure waterproof performance at seams
and corners. Refer to local plumbing codes
for any specific requirements in your area.
Note: A specialized inflatable bladder style
drain plug works best with KERDI-LINE-
VARIO for flood testing.
10
Install the flange with foam supports and
coupling of choice and solidly embed in the
thin-set mortar or KERDI-FIX.
Note: If the drain location is desired to be
close to the wall, orient the flange so the
offset is opposite the wall. Refer to the
provided template for wall placement.
7
Determine the tile layout and install the first
course of tile on the back and side walls.
11
Ensure that the flange and foam support
are firmly embedded. Check to ensure the
KERDI-LINE-VARIO flange is level. The
flange should now be flush with the top of
the shower tray.

Waterproofing
Plumbing Access: When there is no access to the plumbing from below, the flange must be set and connected to the waste line simultaneously according
to Step 6. When there is access to the plumbing from below and the waste pipe can be connected after installing KERDI-LINE-VARIO, you may skip Step 6.
Note: If the KERDI-LINE-VARIO flange is installed in advance of the shower tray, the construction cover is used to protect the flange and KERDI collar from
any damage that may happen on the work site. The cover can be cut to fit in instances where the flange sits tight to the wall.
The construction cover is secured into place until the next steps of installation resume.
