How to deal with Densheild to drywall transition disparity
I think the difference appears to be minimal and you can just leave it.
Take a tile and place in on the denshield so it overlaps the drywall and place the edge trim behind the tile, if the gap between the back of the edge trim and the drywall is an 1/8&quot; or less it will be fine.
A little extra thinset will fill the difference in the depth.
The extruded aluminum edging may not sit flush or down tight to the drywall but that can be hidden with a bead of caulking.
