We recently moved into this place and the shower has this crack in the tiles.
I imagine this is quite bad in terms of humidity creeping into the wall?
Is there a way to fix this without having to redo the entire wall?
Thanks for thinking along!
There's no really universal answer because there are many ways to do waterproofing.
I'd start by removing the trim around the doorframe, light switch, or outlet to check the wall structure - or look for a service hatch on the ceiling to peek at the unfinished top part of the wall.
