I'm working on a shower remodel project. I have chosen to use the Kerdi System under my tile.
Right now, I have 3 locations where my fiber cement backerboard (I know its not necessary with Kerdi but I did it anyway) and drywall meet.
1) left side of shower at an outside corner
2) right side of shower on level plane
3) at ceiling of shower (drywall ceiling w/ 3 edges to fiber cement backerboard)
I know I do not have to finish the backerboard since it is under the Kerdi, but what do you suggest I do for the other transitions? I have considered putting metal corner bead on all outside corners and letting the drywall finisher finish this like its regular drywall.
Any and all help would be appreciated.
