When tiling bathroom floor, I left a 1/4" gap between Hardiebacker and the tub wall. I'm planning to fill this with backer rod and silicone caulk.
I'd like to leave only 1/8" between TILE and tub for cosmetic purposes.
Once I add rod and caulk, can the tile go slightly over top of the backer rod and silicone to narrow that gap? Or should tile stop exactly where the Hardiebacker stops?
I'm new and this is a 2nd floor bathroom so I'm also planning to use Red Guard to be cautious.
