Hi all – I would love some creative ideas to fill a couple of small gaps left by a bad tile installation job. Tile goes most of the way up the wall in the shower stall, and then backer board. There are a couple of places where they left a gap between the tile, the backer board, and the drywall of the exterior walls.
Do I just pack these areas with grout? Mud? Tiny drywall patch? Any great ideas of how to transition them more smoothly? If grout, do I have to worry about the size of the grout based on the size of the area to fill?
