Hogwarts isn’t only a school – it’s a castle, and a historic building.
Apparently, it didn’t always have plumbing.
Pottermore, which is where JK Rowling goes to give little presents to Harry Potter fans about the books, and the world of wizardry, revealed that at one point in wizarding history, they had to use magic to get rid of their business.
For National Trivia Day, the website revealed:
Hogwarts didn’t always have bathrooms. Before adopting Muggle plumbing methods in the eighteenth century, witches and wizards simply relieved themselves wherever they stood, and vanished the evidence.
How… how does one ‘vanish’ the evidence? And where does it go?
The little titbit was shared on a post titled Chamber of Secrets, where Rowling added:
When Hogwarts’ plumbing became more elaborate in the eighteenth century (this was a rare instance of wizards copying Muggles, because hitherto they simply relieved themselves wherever they stood, and vanished the evidence), the entrance to the Chamber was threatened, being located on the site of a proposed bathroom.
The presence in school at the time of a student called Corvinus Gaunt – direct descendant of Slytherin, and antecedent of Tom Riddle – explains how the simple trapdoor was secretly protected, so that those who knew how could still access the entrance to the Chamber even after newfangled plumbing had been placed on top of it.
People are disgusted.
And what about if you're a first year and have a hand-me-down wand that loves to troll you? What if you can't vanish it???
So logistically... wizards soiled themselves?
