The Muggle Studies showroom was a room serving as an antechamber to the Muggle Studies Classroom on the fifth floor of Hogwarts Castle. This room was very spacious and square in shape. On two of the four corners of the room stood dioramas depicting parts of an ordinary Muggle household (such as a living room), and next to which blackboards with explicative diagrams (depicting how Muggles use recliners and the safety distance kept from the screen while watching television). Many other Muggle artifacts are kept in showcases or against the walls, such as radios, post boxes and vaccum cleaners. From the arched ceiling hang magic-powered lightbulbs.
