Waterproofing options for new shower room

Yes. I am thinking - self-love over the mat on the flat part. No leveller on the slope and just make up the height with thinset..?

Autocorrect… agghhh

Self-leveller!!!!!!! 😱

The entire floor is level, and you want to create a slope in the shower area? Thought you already pitched down the shower. You will have to rise up the entire floor to be able to get a pitch down in the shower area.

No… the floor is flat, the shower area is already sloped (a wedi riolito neo tray with a linear drain up against the wall).

I am putting a heating mat everywhere, including the shower area. And ideally I will bed it in a thin layer of self leveller. But I don’t want to do that on the shower area because I don’t want to level the slope!

I think the answer is: use self leveller on the flat floor (not to level, just to cover the heating mat prior to tiling) - and don’t use leveller on the tray, just make up the height with thinset. Ideally I don’t want a junction between the leveller and something else -beneath the tiles - but I can’t see a better way.

Someone must have put a mat on one of these trays….?!

Schluter system would be good for what you are describing over there.

Thank you. I already have the mat - but perhaps the answer is to embed in thinset and cover with membrane (wedi do a membrane too), so I have a flat and even surface to tile on. And I can use the same technique on the tray as I am not bothering with leveller.

Embed the membrane in thinset only, make sure it gets a good bonding.
If the membrane is similar to Schluter then it is easy to install the tiles on top following the manufacturer's instructions.

In the end I put my Big Boy pants on, mixed up some rapid setting leveller, waited 5 minutes, poured it, and raked it back up the slope a few times till I was happy it had set.

I have so many layers going on already I decided against membrane. The mat and leveller are on 50mm wedi board so I am happy there is decoupling.
