No entry due to flooding - Mr Filch

This room was located off the Gallery. It was an out-of-bounds area and was kept locked at all times because it was prone to flood.^[1]

Behind the scenes[]

There seems not to be any way of entering this room in the game and, as such, this door seems to be purely decorative. It seems to be, given its proximity in the game, a reference to Myrtle Warren's frequent bathroom floods.
