The reason I suggested plywood is that I have lots of 3/4" GOS that I was thinking of using. Do you think that it will warp as the Kerdi is supposed to be completely waterproff. I realise that anything can happen such as a hole in the membrane but if carfully installed it should be 100% waterproff.[/quote]
I do what I do because it works, not because I have an excess supply of a specific building item. You can do whatever you want to do, I don't really care.
I should, but I don't.
