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!

Had a crack like that... The wife said "it's only a 5 minute job"
Sadly the (correct stuff - we rebuilt the bathroom side of the wall when we moved in) wallboard had cracked for some reason so 5 minutes to yank out a tile and stick in a new one turned into a mission - chasing the crack in the wall board, cutting the damaged bits, repairing with new pieces then replacing 4 tiles instead of one.
It hasn't cracked again so I must have done something right (or the wall has decided to stop moving)
What's the moral? Do not expect it to be a simple job. If it turns out to be simple, fix it, get a beer and chill. You will probably need to get a bit more involved than just replacing the tile.
Just curious, did you end up removing enough material to observe any mold growth? I’m always wondering how bad these things actually get behind the scenes.
There was no mold - the crack wasn't there long and there was a relatively thick adhesive bed which stopped the water getting to the cement board.
