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!

fill the crack with grout, seal the grout once cured.
The tiles should have a water barrier behind them, or cement board, but if this is the US, it’s a crap shoot.
