Daeseongtang is a public bathhouse in the Dongnae Oncheonjang area of Busan where bathers wash in hot spring water. Inside there is a semi-open-air bath, and the facility combines a hotel-style sauna with a communal bath. It was built only a few years ago, so the interior facilities are clean, the lockers are long, and ventilation works well. The parking area is large, which makes it easy to park a car.
