High-Temperature Sauna
Male
85°C
A Finnish-style far-infrared sauna. Automatic löyly operates every hour on the hour (and at 30 minutes past the hour in the left-side bath), filling the room with a wave of heat rising from the sauna stones. A TV is installed, allowing you to relax while sweating thoroughly. The left-side bath offers a spacious area, while the right-side bath is more intimate for a smaller number of people. The balance of heat and humidity is excellent, gradually warming the body to the core and promoting continuous sweating.

A salt sauna installed only in the right-side bath. By applying salt to the body to promote sweating, it helps lift impurities from the pores and is expected to tighten the skin. It operates at a moderate temperature, making it accessible for those who find high-temperature saunas challenging. The scrubbing effect of the salt leaves the skin smooth, and the refreshing feeling lasts after bathing.

Cold Bath3
Male
17°C
A cold plunge bath with a slightly deeper design at 90cm, allowing the entire body to be fully submerged for cooling. The deeper water depth provides buoyancy when submerged up to the shoulders, enabling a relaxed cool-down. By taking time to cool down thoroughly, the heat is drawn out from the core of the body, enhancing the state of perfect relaxation during outdoor air baths.
