Cita:"Hogwarts no siempre tuvo baños. Antes de adoptar los métodos de plomería Muggle en el siglo XVIII, brujas y magos simplemente satisfacían sus necesidades dondequiera que estuvieran, y luego desaparecían la evidencia", dice el tuit.

Cita:When first created, the Chamber was accessed through a concealed trapdoor and a series of magical tunnels. However, 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.
