The bathroom has been torn apart. Remember the tub in the dumpster?
The space under the window is where that tub sat.
The cantilever failed for a number of reasons:
- the joists didn’t come in twice as far as they projected out
- the joists were notched, we can only guess why
- there was no header over the basement window
- someone may not have taken into consideration how much a tub full of water weighs?
