Travatine over Ditra over Caberfloor 24sqm area - Tile Advice

[MartinH]

Could you please give me your learned advice? I am currently building a house, the master bathroom will be located above the garage with a timber joisted floor (247mm Joists at 400mm centres), Aluminium plated underfloor heating (1mm thick on joists).
Question:- What should the make up be above this?
I want to end up with a warm Travitine floor.
My own thoughts were
22mm Caberfloor
Ditra
Tile.
The joiners are suggesting
22mm Caberfloor
6mm Plywood screwed down
A memberane
The tiles.
The tiles (Ditra) will be professionaly installed, but I need some idea of the makeup thicknesses to ensure that the floor levels between the rooms are close.
Thanking you in anticipation
MartinH

You might want to consider using 22mm WBP ply instead of the caberboard, UFH, ditra on the top of that and then tile on top.

I am not a great lover of 6mm ply in tiling applications as I feel it is a little thin and has the possibility of having voids underneath it. You may also want to consider putting noggins between the joists at 300mm centres as well - BS5385 part 3 recommends this. This will give a very solid floor to work with.
