Tanking/tiling/grout depth

[lagi]

Trying to source the bits for a small size bathroom. I have some reading up to do on tanking.

But as the room is so small, on the scenario that all the walls would be tanked, grouted and tiled.

I have yet to fit any plasterboard to the stud walls yet (as still have pipes to run). But all stud walls will be tiled as will the floor.

What would you suggest fitting to the walls and how much should i add for measurements?

Might be a tad late as I never noticed this one before...........................

25mm for board, impey tanking system and tiles. That allows for 9mm thick tiles.

Thanks, not too late, well behind on this room.
