Hi Folks, I am building a wetroom from scratch, i am a very experienced plumber and bathroom fitter but amazingly have never been asked to do a wetroom before - I have watched a lot of videos on the subject and am happy to pay for and use a tray however it occurs to me that I am building a whole new floor from the exisitng joists which I will have to pack up to the correct levels anyway - would it be feasable to create my own levels using packed up 18mm caber flooring and 12mm marine overply which would then be tanked and tiled with the appropriate falls to the trap.
It is a ground floor job with good manouverability of the trap position. I am not trying to cut corners, I simply prefer this idea to trying to marry up a 30mm timber floor to a 30mm tray - this idea would cut out any potential weakness at the joints. Thanks in advance. ps I know there is an argument for hardibacker cement board instead of marine ply but i have used marine ply for decades with no complaints and tiled floors i fitted decades ago are still in perfect condition - i believe if you fit it properly and use primer then there should be no issues - in this circumstance it will have a 1mm tanking membrane. cheers.
