The Heritage Sauna® Löyly Original is an 8–10 person outdoor sauna designed around Finnish sauna principles and built for high-capacity group sessions. Its 1.6"-thick solid Thermo-Pine walls and insulated spruce ceiling provide a durable structure, while the 122.05" L × 118.50" W × 109.05" H exterior provides a spacious installation footprint. The full bronzed tempered privacy-glass front creates panoramic views while maintaining privacy from outside.
Inside, three-tier L-shaped Thermo-Aspen benches provide tiered seating designed to position users within the sauna's intended heat and steam zone. Mechanical intake and exhaust ventilation provides active airflow, while sloped floor drainage and a sloped outer roof support water management. A buffer above the door helps retain steam inside the sauna. Dimmable LED strips are positioned behind the benches and under the seating, with exterior LEDs for nighttime visibility. The sauna is compatible with a HUUM Hive 18 kW heater with 551 lbs of stones, sold separately, and requires professional installation.
