"You know the Prefects' bathroom on the fifth floor? It's not a bad place for a bath."
Cedric Diggory to Harry Potter about the Prefects’ Bathroom[src]

The Prefects' Bathroom[1] is a special bathroom on the fifth floor of Hogwarts restricted to use by school Prefects, Head Boys, Head Girls and Quidditch captains. It is located on the fifth floor behind the fourth door to the left of a statue of Boris the Bewildered, which only opens when given the correct password.


In one side of the room there are the stalls with toilets inside.[2] Opposite the toilets there is a large, swimming pool-like tub with bath taps surrounding it. The pool-like bath is sunk into the ground and is not above ground. The bath taps all run different-coloured bath water, soap bubbles, foam, towels, and bathrobes.These bath taps are a hundred golden taps surrounding the whole pool-like tub, with a different jewel set in each tap. There are most likely bath supplies on one side of the pool, such as soap, bath oil, bath powder, bath salts, shampoo, hair spray, and conditioner. Looking at the tub, one would imagine it would take quite some time to fill, but it actually fills remarkably fast, considering its size.[3] Under the bathroom there are sewers that can be entered by blasting one section of the wall. These sewers may or may not be a part of the passages and tunnels of the Chamber of Secrets.[4]


"That gives you equal status with Prefects! You can use our special bathroom now and everything!"
Hermione Granger regarding Harry Potter's Quidditch captaincy[src]
After the first task of the Triwizard Tournament, Barty Crouch Jr, disguised as Alastor "Mad-Eye" Moody, tells Cedric Diggory to open the golden egg that contains the clue for the second task under water. Cedric takes the egg to the prefects' bathroom and follows Crouch's advice. Underwater, he can hear the merpeople's song, but it takes him some time to deduce that it is sung by merpeople, despite the fact that the mermaid in a nearby painting is wide awake. Myrtle Warren, who visits this bathroom sometimes to spy on the prefects, witnesses the scene. Cedric then told Harry, in return for telling him about the first task: dragons.

Harry Potter in the bathroom with his golden egg

After the Yule Ball, Cedric Diggory tells Harry Potter to try to solve the riddle of the golden egg while taking a bath in the prefects' bathroom. He also gives him the current password, which is "pine fresh". Harry follows his advice in the night of 21 January, 1995. Awed as he is by the bathroom, he has no idea at first how a bath is going to help him solve the egg's clue. He fills the pool with water and bubble bath from several taps, takes a short swim and opens the egg. As usual, it emits a loud, wailing noise and he closes it quickly. Moaning Myrtle reveals her presence and tells him to open the egg under water, like Cedric did. To Myrtle's delight, Harry solves the clue much faster than Cedric.

One of the first things Hermione Granger mentions when she congratulates Harry for becoming Captain of the Gryffindor Quidditch team in 1996 is that he can now use the prefects' bathroom. Ron Weasley also mentions it while congratulating Harry. It is unknown whether Harry ever used the bathroom in his sixth year. It has pictures of mermaids on stained glass windows.
