How to tile surround over this Durock?
I didn't install this Durock, but apparently the ideal way is to fur out the studs so that the durock can be brought down over the lip of the tub. However, I'm hopeful I can tile this area nonetheless instead of redoing the durock and furring out.
The problem is I still need the tiles to come down over those lips. Therefore, they'd "hang" in the air a half inch or so below the durock. I have no doubt the tiles can withstand that without failing; it's not like anybody will be banging on that area, but I can't very well grout that small space now. I was going to caulk the edges, but caulk doesn't perfectly match grout and caulking the bottom half inch would look weird, too...
I am going to redgard the entire surround area, but before I do what's the proper way to fill in those gaps in pic 1? They seem a little large to caulk?

I've done this before. I used Z flashing behind the backerboard. It extended over the tub lip by 1/2". I put a bead of silicone along the flashing and then set the tiles to hang over to just above the tub. Then just caulk the tile/tub joint.
