I am often disturbed when the neighbour on level 3 in my building takes a late-night shower. But in my scenario it’s because their floor drain pipe extends to the skin of the building and the “catchment bucket” [rainhead? sorry, don’t know proper term] that would normally feed the water into the down pipe and into the drain has fallen off at some stage. So the water pours directly onto the path below, which is right near my own ground floor bathroom window. Basically a localised torrential downpour and very noisy. Not the stuff of soothing rain apps!
(Also not great if anyone should actually want to use the path at that time, since the path is narrow with building on one side and fence on the other.)
