DANGER ZONE! (bathroom)

The portion of the floor marked out as the "DANGER ZONE" (which needs to be expanded now) is where the sub-floor is gone underneath. It all sags a couple inches if you stand on or near it. The toilet moves when you sit down on it. The bathroom is very tiny (literally a "water closet") and with nearly half the floor rotted out, it is very hard to maneuver around in there. I added the "Danger Zone" on the floor because I want to make sure any guests know what they're dealing with.
