Tenant putting shower head in the sink caused flood

[John Deyrup]

The bathroom in our rental has a cartridge that you push in to change from a shower to a bath, and the shower has a hose that lets you detach it from the wall. My tenant said that she had been putting the shower head on the floor when taking a bath. There was quite a lot of water that leaked in from the bathroom into the floor below. If the water is not currently leaking that means that there is not an issue with a leaky pipe, but that water was flowing down the path of least resistance; i.e. the shower to the floor? Does the fact that the floor leaked mean that something is not caulked correctly or is it not possible for floors in bathrooms to handle a lot of water?

Not an expert, but it looks long term to me.
