Hi all, I'm going to be fitting a new shower. I've read plenty of advice on kerdi vs liquid membrane etc etc, but one question I don't see being asked is how much of the wall should you do - lets say my bathroom is 3m by 3m and I'm putting in a 900mm Quadrant. How much of the two walls that touch would you waterproof - just the bit behind the shower and a "bit more" ? If so, can't the water go "around" the matting/membrane then?

So what happens to any moisture that's caught. Does it just trickle down to the (now waterproof) floor and sit there until it evaporates?

Now I'm confused. I was under the impression I waterproof - walls and floor - then fit tray on it, tile down to the tray.

Moisture will just evaporate - If there's water trickling down behind your tiles then you've got problems!

I disagree that's the best way to tank a shower enclosure is to fit the tray and tank down to it. Surely the best way is to fully tank the wall to the floor, then fit the tray, silicone it well with a profile tool, then tile.

When tile to a tray I prefer it fitted with Classi seal, silicone that to the wall, overlap it with tanking tape then also the verticals and paste the lot.
