Thank you for the reply Dave, I will spend a bit more time looking...haven't found the right thing yet, have looked at PHG & Tilefix & also Impey (huge prices), marmox, Topps, Kaskade, maxxus, Schluter, aquafix & others over the last couple of days. I am trying to avoid diagonal cuts in the tiles, prefering a minimalistic look - have built the stud walls either side & the rear of the wetroom is an external wall, so the waste can go straight out into the stack easily, so I want a linear full width 1200 waste which can butt up against the external wall, any suggestions greatly appreciated. I'm now thinking, maybe I could make something myself with a slope to the drain...do you professional guys ever do that?
