[Billy Hunt]

Anyone know where i can get 25mm boards,got to make that up in a wet room to come level with the tray,
seen 20mm and 30mm but not 25mm as yet.
Thanks

What sort of boards are you after? Cement or insulation (or other!) Would 2 layers of 12mm hardiebacker do the job? Should be there or there abouts with adhesive to stick it.

Yeah sorry,It is to go on new floorboards,upstairs wet room.
the two hardibacker together is an option but was wondering if there are any 24/25mm boards out their,save me a bit of time in one hit.

I was going to suggest the same as Bri,, dont know of any 24/25mm boards...

Can't you lower the tray so that you only need the 6mm hardibacker. I have done a couple of jobs where the flooring was removed and cut to fit between the joists with extra dwangs to support it. This meant the tray was now just proud of the floor so a slim board could be used to level off. This also meant that there wasn't too big a step into the room. In your case, adding 25mm boards plus tiles and adhesive could leave you with a 35mm floor difference.

why not use a 20mm insulation board and overlay it with hardibacker screwed right through into the subfloor Should be warm and solid.....

are you going to fitt the tray on top of your floor and then make up the dif . or have you set the tray on top of the joist amd supported in between???
