Bathroom subfloor on concrete slab question

I renovated my basement over the last year and now am down to the final piece of the puzzle:the bathroom tiling job. The whole basement is now floored with Dricore subfloor and floating cork tile over it; about 1 3/8in thick.
The flooring stops by the bath entrance and the bath floor is still slab. So basically I need to build up the bath subfloor so I don't have a ridiculous transition. The slab is fairly clean and level and had thought about a product like ditra on the slab with tile(still not picked out) over. Now am thinking maybe cement board on slab with ditra and tile to ease transition. Do you guys think this is the way to go or am I just dead wrong? Am very inexperienced but low funds tell me I need to give it a go. Appreciate any input. Thanks

"Dead wrong"!!!

You can not satisfactorily install cement board on the slab, DITRA YES, CEMENT BOARD NO!

How about you take the path of least resistance and simply tilt a few pieces of tile at the door to convert from one level to the other? It's a cheap fix and really doesn't look that bad, done it many times.

While my DIY tile book is not clear about underlay, the tile guy definitely is.

I will take the advice and not worry about the transition and leave the cement board on the shower walls.

By the way, I got the Dricore idea from you guys on this forum, best choice I
could have made. My basement is now a real living space and the floor is as comfortable as could be.
Thank You!
