Located on the top floor, the 11th floor, this two-tiered automatic löyly sauna features windows that allow bright sunlight to fill the open space. There is no TV, providing a quiet environment to focus on yourself and sweat thoroughly. The automatic löyly generates steam periodically, filling the room with heat waves that quickly promote sweating. The design allows a visual connection to the indoor and open-air baths, providing a pleasant experience. The two-tiered seating offers ample space, allowing multiple people to use it comfortably.

The cold plunge bath is located right next to the sauna room. Equipped with a chiller (cooling device), it maintains a constant cold temperature. It quickly cools down the body temperature elevated by the sauna, and the sharp coldness is pleasant. The bath is deep enough to submerge up to the shoulders, cooling the entire body. The water quality is clear and clean, with a circulation system that keeps it fresh at all times. The flow from sauna to cold plunge bath to outdoor air bath is smooth, completing the loop seamlessly.
