FLOOR DRAINS
for floor drains with integrated bonding flange
include methods B422, B422C, SR613 and
SR614 in the Tile Council of North America's
(TCNA) Handbook for Ceramic Tile Installation
and Method 326DR in the Terrazzo, Tile
and Marble Association of Canada (TTMAC)
Specification Guide 093000 Tile Installation
Manual.
KERDI-DRAIN flanges are formed using ABS,
PVC, or stainless steel 304 (1.4301 = V2A).
Plastic drain flanges feature a polypropylene
fleece webbing on the surface of the bonding
flange to accept a bond to thin-set mortar. 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 ABS. Drain grates are
available in plain and coated 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 with a
modified polyethylene (PEVA) with non-woven
polypropylene fleece on both sides 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). The KERDI-LINE-FC cover
plate is roll-formed using stainless steel 316
L (1.4404 = V4A). The SHOWERPROFILE-S
anchoring leg is made of recycled, rigid PVC.
The SHOWERPROFILE-S/-R profiles are made
of stainless steel 316 L (1.4404 = V4A) with
KERDI laminated on the backside.

-Systems drain grates are resistant
to most chemicals encountered in tiled
environments. In special cases, the suitability
of a proposed type of material must be verified
based on the anticipated chemical, mechanical,
and/or other stresses. In general, grates should
be protected against abrasion or scratching.
Exceptions and special considerations are
listed below.
Stainless steel can sustain high mechanical
stresses and is particularly well suited for
applications requiring resistance against
chemicals and acids. For more severe chemical
exposure, such as de-icing salts and chemicals
used in swimming pools, we recommend
the use of stainless steel 316 L, which offers
even higher corrosion resistance than the
304. Even stainless steel cannot withstand
all chemical exposures, such as hydrochloric
acid, hydrofluoric acid or certain chlorine,
chloride and brine concentrations.
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, nickel, classic gold,
vintage gold, rose gold, or oil-rubbed bronze
finish and 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 grate
options: Floral (E), Curve (F), or Pure (G). The
style grates are available in brushed stainless
steel with plain, nickel, classic gold, vintage
gold, or rose gold finishes and a range of
textured color-coated finishes including stone
grey, cream, greige, bronze, matte black and
matte white. 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-LT/-LTS 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.
Material Properties and
Areas of Application
KERDI-DRAIN and KERDI-LINE are suitable for

including areas subject to foot and wheelchair
traffic, such as showers and wet rooms in
homes, hotels, schools, healthcare facilities,
etc.
