The handle to the only door in the bathroom is missing
There's a cupboard though, with one side locked but the other accessible
Inside you find a pocket watch
You can click on the latch to open it
There's a 4 digit numbered padlock keeping the other side locked
Using the time from the pocket watch as the digital unlocks the padlock
Inside is a wrench
Trying the wrench as it is does not help with the door situation
Examining the wrench again shows it's jaw is adjustable
Adjust the jaw size
And now you can use the wrench to open the door!
