Cut the 2” (50.8 mm) pipe ush (or max. 1/8“ [3.2 mm] above) to the
oor construction. Make sure that the cut out ts to the Fundo panel
drain. Cut out a 5” (127 mm) diameter hole around the 2” (50.8 mm)
pipe to allow for the wedi drain to be inserted into the suboor while the
cut out area must remain free of deection. The drain and trap have to
be sturdily fastened to the sub oor.
Assemble the drain unit following
the instruction drawing.

Set up a continuous 1/4” (6.4
mm) bead of wedi sealant
along the top side of the wedi
Fundos’ valve groove prole.
Optionally you can apply the
bead on the underside of the
main drain body‘s ange. This
will help keeping sealant off
the threads of the main drain
body when it is inserted.
Drop the drain body firmly into
the sealant.

Installation
Before Installation:
 Have 2 × 4 blocking installed over bottom plate between studs along to
support wedi Building Panel to shower base transition area.
 Suboor is stable, even and load bearing, and meets deection criteria of
maximum L/360 as per IRC. Wooden or concrete structural substrates are
dry and sufciently load bearing considering live and dead load. Wood and
Steel framing is sufciently load bearing, plum and square.
 Floor drain assembly below oor is stabilized, xed and supported in posi
-
tion, and will not sink under water load.
 Only wedi products (Building Panels, Curb, Joint Sealant and Fasteners) are
used for wedi Fundo Shower System assembly.
 Installer has received instructions from wedi Technical Sales Staff or is in
-
formed about proper installation methods as described.

wedi Shower Bases can be cut to size using a skilsaw. The Z notch channel
must be remade and cleaned from sawdust or other possible contamination
 Follow applicable state or local plumbing codes requiring specic and
dimensioned waterproofed areas for a shower system or other wet
room installation. Requirements in this manual supersede local plumb-
ing codes; they extend and are not in conict. wedi Shower Systems
or other wet room installations in which non-wedi product is also used
require specic
project recommendations by wedi and may reduce the
extent and installation
area of protection offered by wedi’s warranty. .
 Ensure that no fasteners are used and penetrate through any horizontal
building panel or shower base surfaces in shower or immediate wet
rooms. This includes tub decks, pony shower wall tops, curb tops made
from building panels, seat tops. wedi panels in such areas are installed
in a full surface applied thinset mortar setting bed.
 Seams in the assembly, which are not flat transitions or right angle
inside corner connections, are treated with these extra steps:
 Assembly parts are installed tight and offer a minimum of ½ in. wide
continuous contact/ adhesion surface between two parts, inside
which wedi joint sealant is continuously applied.
 wedi joint sealant is applied over these seams topically, and 1 in.
wide on both sides of the seam.
 wedi mesh tape is installed over these seams and covered with joint
sealant 1 in. wide on both sides of the seam.
