Area Around Shower

[Jared Schroeder]

Hi,

My wife and I just bought our first rental house. It looks great and have a tenant lined up. We were redoing the caulking around the bathtub/shower and noticed right at the end of the tub on the floor, it is squishy. Looks like it gets wet there whenever the shower is used. The bathroom is carpeted, so I am unsure of what's going on underneath. From underneath, it seems ok. Not like there is a hole or anything, but just wondering what you guys thought? Is there any way to keep the water from getting out? The shower curtain only goes to the front of the tub where it starts curving, so water is splashing out on the floor. The shower in my residence is a walk in shower, so I have never had to deal with this issue. Any advice or suggestions would be much appreciated!

Thanks in advance!
