2nd Floor Bath Issues..Please Advise!

[Anthony Nelson]

I have a 2nd floor bathroom at one of my rentals and I visited it yesterday. The tenant showed me that the drywall in the kitchen ceiling (right below 2nd floor bath) had some soft spot. When I went upstairs I noticed that the shower door does show some signs of water on the bottom outside. I also think it has something to do with the tenants getting out of the shower soaking wet and not drying the floor, but I cant prove it.

My question is if anyone has anything that they do to their rentals in order to combat the idea of the tenants getting out of the shower soaking wet? I plan on removing the shower door, cleaning it all up, re-siliconing and re-caulking all around it so it has a good fit. Im just concerned that the tenants will continue to get out of the shower soaking wet. Please advise if anyone has anything they do to fix this issue. Thanks
