The Boiler Room is an underground room below the Dance Club in Club Penguin. Located here is the Boiler, which serves as a power source for the entire island. Also located here is a large filing cabinet, which hosts old issues of the Club Penguin Times; however, only the most recent six are viewable.

The Boiler Room can be accessed by climbing down from a fake speaker in the Dance Club, or from a door on the left side of the Underground Pool. Aside from the boiler and filing cabinet, the room is fairly sparse. On the back wall, there are a variety of tools and a fuse box, but these are only viewable in missions.
