Point drainage on screed substrates (horizontal)

Fundo One-Step shower system

Before Installation:

- Subfloor is stable, even and load-bearing, and meets deflection criteria of maximum L/360 and requirements as per IRC. Wooden or concrete structural substrates are dry and sufficiently load-bearing considering live and dead load. Wood and Steel framing is sufficiently load-bearing, plum and square.

- Floor drain assembly below floor is stabilized, fixed and supported in position, and will not sink under water load.

- Installer has received instructions from wedi technical sales staff or is informed about proper installation methods as described.
Step 1 Step 1 Cut the 2” pipe flush to the surface of the floor construction. Make sure that the cut out fits to the One Step base drain. Cut out a 5” diameter hole around the 2” pipe to allow the wedi drain to be inserted into the subfloor. The drain and trap have to be sturdily fastened to the sub floor.
Step 2 Step 2 Set up a continuous 1/4” bead of wedi sealant along the top side of the wedi One Step valve groove profile. Drop the drain body firmly into the sealant. Turn the One Step pan upside down and apply the rubber and the fiber gasket. Tighten the gaskets firmly to the pans steel ring.
Step 3 Step 3 Dry fit the base and make sure that floor drain is located in the center of the wedi drain. Make sure the base walls are square and tight with the framework.
Step 4 Step 4 Apply a bed of modified thinset on the floor using a minimum 3/8" x 3/8" or max. 1/2" x 1/2" square notch trowel. The whole contact area for the base must be covered.
Step 5 Step 5 Press the Fundo One Step firmly into the thinset bed, ensuring that the installation is level and void free. Apply some weight equally and for at least 30 minutes (thinset bags).
Step 6 Step 6 Set up the rubber caulking gasket (bevelled side up) around the 2” pipe in the subfloor. The rubber gasket must be flush with the upper end of the 2” ABS or PVC pipe. Tighten the connection using caulking nut, metal guide and screw driver.
Step 7 Step 7 You can now install waterproof wedi 1/2" building panels directly to the framework and seal all joints and fastener points as usual and per wedi building panel installation guidelines. (you may install other Backerboards but have to add topical waterproofing / membranes).
Step 8 Step 8 Your shower is ready for tile!
