I have a 2m x 4m bathroom. There is going to be a wetroom former at one end. I also want electric underfloor heating installed. The subfloor is a suspended timber floor boards. Whats the best way to go about this, I advised tanking the shower area, and reinforce floor, adding noggins and replacing floor boards with 25mm ply then over laying 6mm cemment board, then heat mat then slc then tile?? Not usually something i deal with and want to ensure the correct prep is done as i have serious doubts about the builder who is project managing, he says i wont need to envelope the tiles in the former as its an "novolinni". We all know tiles dont bend so need to see exactly what he is talking about?? anyone heard of this? I will be tiling with polished porc tile. Does my prep sound ok?

the prep sounds ok but make sure the cement boards are laid with adhesive and screwed. be careful with the polished porcelain as they'll be very slippy when wet

i'm not familiar with that tray and it's hard to tell on the video

No envelope needed

what do you do about the little step directly above the v? you can see it when the ply's being laid at about 4mins 10 secs of the video
