The indoor pool temperature ranges from 94 to 98 degrees F, and the sides and bottom of the pool are lined with a porcelain-smooth layer of pale pink mineral deposit, the result of decades of contact with the mineral water. Like all swimming and soaking facilities in Hot Springs State Park, the pools and steam room at Star Plunge are supplied with hot mineral water from the nearby Big Spring.
