GIRLS ONLY! STAY OUT, POTTER AND WEASLEY! The funny inscription etched on this door with a potions knife reminds us all of the great deeds Harry Potter and his friends performed in this very bathroom. Today it is fortunately no longer nearly as shifty as it used to be. Nevertheless, this bathroom is still haunted by the one and only Moaning Myrtle and, if you happen to speak Parseltongue, can gain access to an empty Chamber of Secrets.

If you are ever in need of extra toilet paper or a towel dispenser needs to be restocked, there is a small cupboard across from the sinks containing all of the bathroom necessities you could ever need. Do the caretaker a favour and keep this restroom clean and in tact. The toilets should only be used for, well, your bathroom business -- not for brewing advanced potions. And please try not to upset Myrtle in any way so she doesn't burst into a loud fit of crying and wailing and decide to flood the bathroom and the corridor outside for the millionth time. Be nice to her, even if you must lie.
