wedi Fundo Ligno Recess Kit Installation Guide

1. Measure and mark the area of subfloor to be removed. Use a circular saw to cut close to the framing. wedi recommends a

combination of saws (i.e. sawzall or rotary cutter tool) where a standard circular saw might not reach. Ensure the 2 in. floor

waste pipe is installed and positioned to fit the Ligno shower base drain. The pipe is cut square and even at 5/8 in. below

the recessed subfloor top surface. A 6 1/2 in. cutout must be made into that floor strip with the drain pipe in its center. It

is important to position the drain and cutout to not interfere with a floor joist.

2. 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. Do not use joist brackets shorter than 12 in, or equipped with less than two (at least

partial) mounting flanges.

3. Install the joist brackets to the floor joist using the pancake head wood screws provided by wedi. Set one screw per each

mounting flange in the center 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 the top and side of floor joists, but allowing for up

to 1/8 in. and minimum of 1/16 in space between the floor joist‘s vertical side and the metal bracket. This helps to mitigate

joist expansion/contraction, and irregularities without creating too much tension.

4. Fasten the next bracket on the other side of the floor joist. The mounting tabs must be staggered from those on the first

bracket; this may require cutting the second bracket.

5. Repeat the process shown under step 4 and install joist brackets to all exposed joists.

6. Place C brackets at the wall sides. The C brackets are installed at both ends of the recess area first, and then along the wall/

side every 12 in. (center of C bracket to center of C bracket).

7. The C brackets are inserted with their claws between the floor surface and the underside of the base plate. Use a wood

block or a hard rubber mallet to push the C brackets into position.

8. Make sure the C brackets are mounted in a level position (assuming a level base plate), and use the longer Phillips self-

drilling screws with wings provided by wedi. Fasten through the base plate and into the metal claw resting between the

base plate and the wood floor top.

9. Install one C bracket against the wall, and centered between each pair of floor joists.

10. Dry fit C brackets to the edge of the wood floor to ensure C brackets can be installed for full support along the edge of

the floor plate. Use a wood block or hard rubber mallet to push the brackets to position.
