Material Properties and
Areas of Application
KERDI-DRAIN drain casings are formed
using ABS, PVC, or stainless steel 304
(1.4301 = V2A). Plastic drain casings
feature a polypropylene fleece webbing. The
KERDI-DRAIN adaptor kits feature adaptor
rings made of stainless steel 304 (1.4301
= V2A) with thermoplastic rubber gaskets
and adaptor flanges made of stainless steel
304 (1.4301 = V2A) or ABS. Drain grates
are available in stainless steel 304 (1.4301 =
V2A) and anodized aluminum. The covering
support is stainless steel 304 (1.4301 = V2A)
with KERDI laminated on the surface.
The KERDI-LINE channel body is formed
using stainless steel 316 L (1.4404 = V4A)
and features a bonding flange with a KERDI
collar laminated on the surface. KERDI is a
bonded waterproof membrane made of soft
polyethylene, which is covered on both sides
with a special fleece webbing to anchor the
membrane in the thin-set mortar. The frame
and grates are made of stainless steel 316
L (1.4404 = V4A). The channel support
is made of pressure-resistant, expanded
polystyrene (EPS).
KERDI-DRAIN and KERDI-LINE are suitable
for use in residential and commercial
applications, including areas subject to foot
and wheelchair traffic, such as showers
and wet rooms in homes, hotels, schools,
healthcare facilities, etc.
The KERDI-LINE-FC is roll-formed using
stainless steel 316 L (1.4404 = V4A).
Stainless steel can sustain high mechanical
stresses and is particularly suitable for
applications requiring resistance against
chemicals and acids. However, even stainless
steel is not resistant to all chemical stresses,
and may be affected by hydrochloric and
hydrofluoric acid or certain chlorine, chloride
and brine concentrations, which may be
present in detergents or swimming pools. In
special cases, the suitability of the selected
floor drainage system must be verified based
on the anticipated chemical, mechanical,
and/or other stresses.
Anodized aluminum retains a uniform
appearance during normal use. The surface,
however, is susceptible to scratching and
wear and may be damaged by grout or
setting material. Therefore, these materials
must be removed immediately.
Various configurations of KERDI-DRAIN and
KERDI-LINE are listed by UPC
®, CSA, NSF
and ICC-ES PMG.
DRAIN adaptor kit is particularly useful in
renovations where the clamping ring drains
are difficult to replace with the standard
KERDI-DRAIN (e.g., when they are set in
concrete slabs).
The KERDI-DRAIN grate assembly consists
of a frame, which can be seamlessly
adjusted to the thickness and layout of the
ceramic tile or stone covering via the height
adjustment collar and lateral adjustment
ring, and grates or cleanout covers that are
placed within the frame. The 4" (100 mm)
standard grate assembly frame features an
approximately 1/8" (3 mm) wide reveal after
installation and grate/frame combinations
are available in stainless steel with plain,
chrome, or oil-rubbed bronze finish or
anodized aluminum with brushed nickel,
brushed copper, or brushed brass finish.
The 4" (100 mm) style grate assembly frame
features a minimal reveal after installation
and can be combined with one of three
brushed stainless steel grate options: Floral
(E), Curve (F), or Pure (G). The 4" (100 mm)
covering support is a square stainless steel
plate with KERDI laminated on the surface
to allow for bonding of ceramic or stone tile,
which creates a virtually invisible drainage
line. The 6" (150 mm) square and round
stainless steel grate assembly frames feature
an approximately 3/16" (5 mm) wide reveal
after installation and can be combined with
stainless steel grates or cleanout covers.
Please note that grate assemblies included
with the plastic KERDI-DRAIN featuring 3"
(75 mm) outlets and the residential adaptor
kits only allow vertical and tilt adjustment (no
lateral adjustment).

-KERDI-LINE is a low profile
linear floor drain specifically designed for
bonded waterproofing assemblies. KERDI-
LINE can be installed adjacent to walls or
at intermediate locations. The floor can be
sloped on a single plane to KERDI-LINE,
which enables the use of large-format tiles
and creates interesting design opportunities.
KERDI-LINE consists of a formed stainless
steel channel body and grate assembly or
covering support to which tile is applied.
The channel body features a standard 2"
(50 mm) no-hub outlet and is attached to
the pipe using an appropriate mechanical
(e.g., flexible or no-hub) coupling. The simple
connection to standard drain outlets makes
KERDI-LINE suitable for new construction
and renovation. KERDI-LINE is available
with both center and off-set outlets. The
off-set outlet is located 8" (20.3 cm) from
the edge of the channel body and provides
flexibility when obstacles (e.g., floor joists) are
encountered during installation. KERDI-LINE
includes a corresponding polystyrene foam
channel support to set the drain elevation to
the corresponding KERDI-SHOWER-L/-LS
shower trays. The perimeter of the channel
body consists of a bonding flange laminated
with a collar made of KERDI. It ensures a
simple and secure connection to the bonded
waterproofing assembly, both in the floor
area and on adjacent walls. KERDI-LINE is
available in channel lengths from 20" to 72"
(50 cm to 180 cm) in 4" (10 cm) increments.
The bonding flange extends approximately
1" (2.5 cm) beyond the channel on all sides.
The KERDI-LINE grate assembly consists of
a stainless steel frame that can be seamlessly
adjusted to the thickness of the ceramic
tile or stone covering – 1/8" to 1" (3 mm
to 25 mm) for standard grate assemblies
and 1/4" to 23/32" (6 mm to 18 mm) for
style grate assemblies – and stainless steel
grates that are placed within the frame. The
standard grate assembly frame features a
3/8" (10 mm) wide reveal after installation
and can be combined with one of two grate
options: Closed (A) or Perforated (B). Each
standard assembly is available in a brushed
or chrome finish. The Perforated (B) option
is also available with a locking mechanism
(brushed stainless steel, 3/4" – 19 mm
frame only) for applications where tamper
resistance is desired or required (e.g.,
healthcare and education facilities, etc.).
The style grate assembly frame features a
minimal reveal after installation and can be
combined with one of three grate options:
Floral (E), Curve (F), or Pure (G). Each style
assembly is available in a brushed finish. The
covering support is placed flush with the
top of the channel body and can therefore
accommodate any thickness tile covering.
If KERDI-LINE is placed at shower entrance,
it is recommended that grate assembly A or
the covering support is chosen and that the
drainage openings span the maximum width
of the entrance to limit potential overflow;
secondary drainage (e.g., KERDI-DRAIN)
may be required in the drying area.

-KERDI-LINE-FC is a stainless
steel cover plate for use with KERDI-LINE to
create a seamless look in applications where
multiple drains are installed end-to-end.
KERDI-LINE-FC is available in a brushed or
chrome finish, and is designed for use with
either the solid or perforated grates with
brushed stainless steel frame.
