This boys' bathroom was located on the sixth floor of Hogwarts Castle, on the passageway by the marble stairs leading to the Seventh-floor corridor.


On 17 March, 1997, after Defence Against the Dark Arts class with Severus Snape, Ronald Weasley and Harry Potter walked into this bathroom while discussing the upcoming Apparition tests. There, they found Myrtle Warren expecting a young boy to come in. The ghost says that the youth is very upset and has been confiding in her and when Harry asked her who he was, she tells him that she swore to take his secret to the grave. But before she could finish her sentence, Ron interrupts saying that this is not much as she is already dead, and that she would do it "more like to the sewers" — upsetting the ghost who, with a howl of rage, left the bathroom.[1]

About a month later, Harry, who had been looking for Draco Malfoy (whom he suspected of being working for the Death Eaters from inside the Castle) in the Marauder's Map, found that the boy was in this bathroom in the company of Myrtle. As Harry quitely pushed the door open, he listened as Draco cried and as Myrtle offered to help him. Realising that Harry had been listening, Draco drew his wand, starting a duel. Remembering about a spell he had read about in the Half-Blood Prince's copy of Advanced Potion-Making, Harry cast Sectumsempra, heavily wounding Draco. Severus Snape arrived at the scene, and healed Draco, but had to take the boy to the Hospital Wing. Harry was then given detention with Snape for every Saturday until the end of term.[2]
