Bathroom Floor tiling

[rickl]

Hi. I am about to tile a bathroom floor however the level of the bottom of the tile is about 25-35mm from the current floor level (concrete slab). Waht is my best option? Should I lay a "new" bed first (sand and cement) or can I use a sand/cement mixture, maybe with an adhesive additive, and lay the tiles direct as I build up the level? Suggestions appreciated.

If so I would screed it first.

What ever you do, don't forget that you will need to apply a waterproofing membrane at some stage. Preferably on top of your screed.
