I wouldn't use a foam cored board behind a wall hung toilet with thin tiles.

One more question. I am fitting a wall hung toilet and vanity unit. What thickness Kerdi board would be best to use under Porcel-thin tiles?
Cheers
John..
I generally fit 18mm ply behind where the toilet will hang, just around the footprint of the toilet plus 20mm or so, so that the ply takes the weight of the toilet and not the backer board and tile.
If you’re going t sit the toilet on the tile and not cut tight around it, drill all your holes, do not cut out a diamond shape to accommodate pipe work.

Yes I’ll tape joint Jerry, but look at it this way, you have two bloody great 10 inch bolts pulling the toilet and ply on to a frame, with just enough ply sticking out to sit on metal frame. Exactly where is it going to go? Drilled holes have a much higher chance of success than a sodding great hole with a pan stuck to it.So do you not anything between tile and plywood other than adhesive and if not do you scrim the joints or anything like that .
Cut a diamond shape ? How rough do you think I am
John..
Haha didn’t even see your post til now.I wouldn't use a foam cored board behind a wall hung toilet with thin tiles.
I would of drilled the holes anyway, not just cut a chunk out. I will be taking my time doing it all. As you can probably guess I have done a fair amount of research on it all
It’s just a pain all my joinery tools are all pretty useless to help me out doing this type of work. Well apart from a laser level and a cordless drill.
John..
Whatever works for you mate. Kool.What I have done before when drilling tiles is form a circle out of blu-tack a bit bigger than the hole and pour some water in it

Thin porcelain behaves no different to glass in actual fact, a lot of the original tooling was derived from the glass industry, and we still use it now.Thinking about it, it wasn’t tiles it was glass I was drilling
What do you use to match the thickness of the ply as far as i am aware tbb doesnt come in 18 mm or am i missing something .Yes I’ll tape joint Jerry, but look at it this way, you have two bloody great 10 inch bolts pulling the toilet and ply on to a frame, with just enough ply sticking out to sit on metal frame.

The point of it is that the ply will not crush at all, where’s as the same cant be said for backer boards can it. (Obviously depending two things, how accurately the plumber has secured the pan, and secondly, who exactly is going to be putting their full body weight on the pan. If the substrate flexes, so will the tile. And if anything does develop a leak, it’ll be behind the boarding anyway no matter what it’s made of.
