Measure and mark subfloor to be removed. Use a safe saw to cut close
to the framing but also in a safe and clean way. wedi recommends a
combination of saws including a sawzall and a saw like Dremel (r) US40
01 120 V where a standard circular saw might not reach.
Make sure your 2“ (50,8 mm) floor waste pipe is installed and posi-
tioned to fit the Ligno shower base drain. The pipe must be cut 5/8 inch
(15,9 mm) below the surface of the recessed floor to be installed be-
tween the joists. A 6 1/2“ (165,1 mm) cut out must be made into that
floor strip with the drain pipe in its center. It is important to position the
drain and cut out to not interfere with a floor joist.

Cut the joist brackets to the
length of the exposed floor
joists. Depending on length
and direction of floor joists
you may need to add a shorter
joist bracket. Please do not use
joist brackets shorter than 12“
(304,8 mm) or equipped with
less than two (at least partial)
mounting flanges.
Install the joist brackets to the
floor joist using the flat head
Phillips wood screws provided
by wedi. Set one (1) screw per
each mounting flange in the cen
-
ter screw hole (unless bracket is
cut which is when at minimum
two mounting flanges must be
fastened using available screw
holes). Brackets should be aligned
with top and side of floor joists
but allowing for up to 1/8“ and
minimum of 1/16“ of space be
-
tween the floor joist‘s vertical side
and the metal bracket. This helps
mitigating wood movement and
irregularities in the floor joist it
-
self without creating too much
tension.

Recess Kit
The Fundo Ligno Recess Installation Kit is designed to help you recess a
wood floor between existing floor joists (2x10 joists, engineered or I joist
construction) without the need of sistering these joists with more 2x6
or other wood framing material. It will add safety in terms of structural
stability of the recess, but will also allow for a safe installation process,
and save much time compared to working with framing material only.
The wedi recess bracket support system will allow a 3/4” wood floor to
be solidly situated between and flush with joists. The bracket system con-
nects, carries and supports the recessed wood not only along floor joists
but also along surrounding subfloor (not recessed) as well as sides of the
shower where the wood meets the framing bottom plates.
Please ensure the general subfloor construction, prior to installing the
wedi system meets current IRC requirements for structural construction
and dead and live load minimums, as well as a deflection potential of
less than L/360. Once the wedi Bracket System is installed, and the
recessed floor is in place, all requirements will still be met or exceeded.
The system comes in one box equipped with two different profile types
and all the hardware needed. One Kit covers recess spaces for a Fundo
Ligno up to 5 × 5 ft. in size. Do not use this system for any other re-
cessed shower installations except wedi Fundo Ligno system.
