Hi, this is my first post so be gentle please.
I'm about to start tilling the bathroom floor and although I've some experiance tilling walls, this will be my first go at a floor.
The first problem I have is how high the bathroom floor would be if I had to glue and screw over the floorboards and then use either a backer board or Ditra matting (yes I've read some of the other threads before posting )
The gap between the top of the bathroom joists and the bottom of the batroom door / landing carpet is 32mm ish so I could probably eek that out a bit more without it looking too much of a step up.
My tiles are 8mm thick and if I go with 6mm adheshive and 2mm back butter I'm left with 16mm to put plyboard and anything else thats needed down.
My question I guess is that if I were to remove the floorboards could I just put ply straight onto the joists without it causing any issues and what would be best, going with an 18mm ply and tilling straight on top of it or getting a 12mm ply and using Ditra/backer on top.
Thanks for any help you can give me and I hope there's not too many people just shaking their heads at me
Chris.
