Hi all can I pick your brains? I've been tiling a few years now but not tackled a full wet room. I've done bits of tanking ect. I'm looking at a job with a builder friend and My questions are what's your favourite products, on new build chip board flooring is it best to pull up floor and re-ply or possibly board over with product? Best suppliers ? Membrane or boards. Please feel free to answer individual questions or the lot. Thanks for looking
