Treasure Room shitter!

Near the Hogwarts Castle grand staircase you’ll find a door that can be opened with a lil’ math puzzle that will reveal this pirate’s locker of shitters and other sanitation fixtures. I’m delighted to see this of course, but also - why is this here? Why would they need to store extra cisterns, bowls, sinks, and tubs anywhere, when they have a Room of Requirement that can effortlessly create anything they might need out of thin air?

This Hogwarts Legacy shitter represents a $5 donation to Plan International USA!
