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?
My house has one of those types of detachable showerheads, and you control switching the shower and bath by pulling up a thing on the bath spout. The showerhead has a holder that you can attach it to when not holding it.
I would never, ever just lay the detachable showerhead on the floor. Due to the system not cutting off water to the shower when the bath spout is selected, a little water will always come out, and I would bet doubly so if the shower head is laid down on the ground. I would bet that is the problem, OR she isn't tucking the shower curtain into the tub when she runs the shower.
Also no, bathroom floors are almost never intended to take much water. I also would never install one of these detachable showerheads in a rental unless it was required by an elderly/handicapped tenant.
Lesson learned about the detachable shower heads. The wood here was also very soft from the water; can a single event make the wood that soft or is more likely that multiple events caused the wood to rot.
@David Lee Hall, III Can you be more specific on what damage you are seeing. To put the image in context, the bathrooms had drop ceilings installed for some reason in the past, previous to the drop ceiling there was plaster and lathe which was half heartedly removed. The image you are seeing is the ceiling beneath the drop ceiling on the first floor and the blackened wood is where water was dripping from the second floor. Most of the wood that is visible is lathe.
Wood won't get that soft from a single event. The showerhead should have a holder that it sits in when not being held in the hand. The same one that allows it to be used as a shower.

Okay. Pictures on my phone aren’t quite that clear. I thought that was moldy, rotting cross braising.
