What to board on new bathroom floor prior to tiles ?

[Mehul9216]

Hi All

Just about to get my bathroom refurbished. Whole lot is coming out, and new suite and tiles etc going on.

The floor and the joists will be re-inforced to ensure that it is as stable as possible, as we have got tiles cracking on the floor currently ?previous poor installation, not sure, but this time round we don't want it to happen. House is only 10 years old, and otherwise built pretty well.

I am getting very confused. The bathroom person will be taking all the floor up, and then putting down new board. But should it be hardibacker, no more ply, ditra mat ? What thickness of the board should we use ?

What should go under the shower tray ? The same board ? or something different. The last shower tray starting to leak around the tiles, and into the kitchen, so dont really want that again.

Should the shower tray be bedded down onto cement ? Or glued down ?

Sorry for all the questions !

Hi Ashtray - thanks for the advice - what do you mean by "putting perimeter noggins and noggins on any joins" - just want to make sure that the builder does what I tell him to, and that I look as if I know what I am talking about ! Do you mean on the joists ?
