Thanks Dave,
that explains it a bit better, like you on the pic I want to use travertine marble and I couldt get me head round how the fall would work but now I see it !
I take it you need to try and get the biggest tray for the available space ie mine measures around 1300mm x 800mm so i presume i need a tray around this size ?
I will have a look at the Wedi trays tonight to get more of an idea of how it all works
Pics will be no problem once I get up and running, still in the planning stages at the Mo.
Thanks Rich.
