SunRay Seneca 3-Person Contemporary Outdoor Sauna With Harvia Heater

The Seneca 3-Person Outdoor Contemporary Sauna blends modern design with authentic traditional sauna performance, making it a refined addition to any backyard or outdoor living space. Built for durability in harsher climates, it features a maintenance-free metal roof and a sealed weatherproof red cedar cabin that protects against the elements while maintaining a clean, contemporary aesthetic.

Inside, the spacious cabin includes a deep bench with an ergonomic backrest, providing comfortable seating for up to three adults or enough space for one person to fully stretch out and recline. Powered by a Harvia 6 kW electric heater, the Seneca delivers intense traditional heat, reaching temperatures up to 170°F for a deeply restorative sauna experience.

To enhance each session, the Seneca includes a water cask and ladle for creating steam and adjustable humidity, along with a hygrometer and sand timer to monitor comfort and session length. Interior dome lighting with automatic shutoff creates a relaxing ambiance, while the easy-assembly design makes this sauna a convenient and long-lasting outdoor wellness retreat.
