Start with the main wall and cut a notch in the first Wedi board for the shower bench.
Ensure the rabbet cut in the Wedi Fundo Primo shower pan is clean. Then fill it with Wedi Joint Sealant.
Also apply Joint Sealant along the perimeter of the shower bench that’s up against the main wall.
Embed the first Wedi board in the Joint Sealant and start the first set of screws/washers 4 inches above the shower pan.
Add successive screws and washers every 12 inches.
We built a custom 16″ shower niche using Wedi Board. Existing 2×4 framing was cut from the niche using a Fein oscillating tool.
And a portion of second Wedi Board on the main shower wall was in that niche area.
The bottom wood blocking for the shower niche was slightly sloped downward and secured to the studs with 3″ decking screws.
We added 2×4 wood blocking in the main wall for grab bars. Then applied Joint Sealant to the top of the first Board and installed the second Board on top of it. Again adding screws and washers every 12 inches along the stud.
Cut a notch in the bottom Wedi Board for the curb. Then puncture the back of the Board to indicate the mixing valve location. Cut holes for the mixing valve and plumbing ports with a utility knife or hole saw.
Add Wedi Boards to the plumbing wall using the same protocol as the main wall, i.e. Joint sealant on the top edge of successive Boards and screws/washers every 12 inches.
Start the shower bench wall by adding a thick bead of Joint Sealant to the top of the bench. Then embed the Wedi Board in that Joint Sealant and attach it to the studs. Complete the shower bench wall like the main wall.
Apply Joint Sealant to all the vertical and horizontal seams as well as screws/washers. Smooth the Joint Sealant with a Wedi corner putty knife or 3″ putty knife. There should be a 3/4″ to 1″ bead of Joint Sealant on either side of seams.
The last step is to add a mixing valve and pipe seal. Our video shows the details on how to do this and the complete Wedi Board Installation

So for the extra pipe holes; you do not make a sealant to pipe connection or do you just basically make a dam?
I used one of these flexi collars around my shower head pipe. If I need to change my shower heat pipe. Can I remove it from the collar/flange and reinstall the new shower head pipe thru the collar – and it will still be water proof?
I can't believe this shower system relies on CAULKING AT THE BOTTOM!!!!!!!! I mean seriously people, this defies all logic and common sense…You better pray there is no movement in that shower/pan/bench, or in 10 years you'll be replacing the rotted out structure under this shower…
WHY NO JOINTING TAPE OVER THE JOINTS?
What u put on floor brother
Hello there, at 7:29 what type of thinset is being used? Modified or unmodified?
Can I use formica laminate sheets with the wedi board instead of tiles? I would think so but you’d probably have to use an epoxy or something similar to make it adhere to it. Please let me know because it’s what I have already. Thanks and awesome educational video! Keep up the good work.
I put in wedi board for the backsplash on a soaker tub 4 years or so ago. I believe Then the correct procedure was to notch half the width of the two boards and lock them into each other (top board notch back half bottom board notch front half out. Also believe I did this for the side seams too. When did this all change? Putting in a shower soon and don't want to mess up.
Great video. About to install my system. What exactly is the power tool you are using to make the delicate cuts – like cutting the wood for the custom shampoo box?
Doesn't wedi say start screws 12" from bottom not the 4" you did?
