Wall tiling with with rounded drywall corners

pmarkham72

I need some serious assistance here. I am going to be installing tile (6 x 6) in my master bathroom on the walls. They have textured paint which I'm going to sand and use mastic. The big issue I have is I have rounded drywall corners, which means no door casings.

A. How do I break up going from the hallway to the bath with nothing to go by? Just have to get close to the edge where it starts to round and put in a piece of schluter?

B. What is the best way to tile around the rest of the outside corners? Do like they did with the baseboards...2 - 45 degrees cuts? I doubt they'll stick though. Or just bring it to a 90 degree and have a little space between the edges and the rounded corner?

Any help would be appreciated.
