Myrtle's Bathroom is located on the second floor of Hogwarts, and was once used by female students, until Moaning Myrtle was killed by Tom Riddle, who set the Basilisk on her. It has been out of order ever since Myrtle began haunting the bathroom, and students avoid it. The sink with the snake-embossed tap is the entrance to the Chamber of Secrets, which is accessed by speaking the words "Open up" in Parseltongue. It was used by Tom Riddle to open the Chamber of Secrets, and by Harry Potter, Ron Weasley and Hermione Granger as a hiding place to brew Polyjuice Potion. Later, Harry Potter, Ron Weasley and Gilderoy Lockhart opened the Chamber of Secrets and it was accessed again by Ron Weasley and Hermione Granger to open the Chamber of Secrets and destroy Helga Hufflepuff's Cup with a Basilisk fang.

Gabriella slowly pushed open the door to the bathroom, trying to desperately to be quiet but to no avail as the door was already creaking far too loud for her to be sneaky. She carefully peered in and looked around before quietly moving to the sink. She definitely did not want Moaning Myrtle to bother her right now and just needed a few moments to think; all day she had been around other students and all of their thoughts had caused such a headache for Gabriella.
