The Sentinel Hybrid 2 puts both heat types in one 16.8 sq. ft. room: Pure Infra far-infrared panels for gentle, penetrating warmth, and a Piccolo heater for authentic Finnish löyly. Both run from a single SaunaLogic 3-H control with a colour LCD touchscreen, Wi-Fi and a mobile app, and the whole room plugs into a 120-volt outlet (15- or 20-amp). Okoume lines the interior and exterior, with an all-glass front wall, multi-colour LED chromotherapy, Bluetooth speakers and a heater drip pan.
Explore our innovative sauna features
The SaunaLogic2® control can be activated from anywhere. Worldwide mobile functionality lets you take your control with you and set your sauna up to be ready when you are. The intuitive glass touch screen display lets you control timing, temperature, lighting and system status. Bluetooth functionality is built in to support an optional audio kit, and within the mobile app you can set up preferences by user, manage calendar programming and control all sauna features.
All Finnleo sauna series include color therapy lighting systems, discreetly integrated into the backrests or ceiling. In addition to white light, the LED lighting system can create six different colors — red, green, blue, yellow, turquoise and violet — so you can choose the color according to the mood desired.
Hallmark, S-Series and InfraSauna rooms include a built-in Bluetooth® sound system so you can stream audio straight into the room. Styles may vary by sauna. On NorthStar, Designer and Euro saunas the Bluetooth audio sound bar is available as an option.
Finnleo's patented CarbonFlex® carbon fiber heating panels produce the deep, soft, even heat you expect in an infrared sauna. Coverage runs wall to wall, side wall panels extend to the floor, and bench seat heaters are included, guaranteeing head-to-toe comfort. While the ambient air rests somewhere between 120˚ and 140˚ F, your core body temperature rises as it absorbs the infrared energy.
Finnleo's patented low EMR/EF far-infrared technology soothes and heals safely. In a Finnleo sauna the infrared waves penetrate deep into your body, warming you inside and out. EMR and EF performance is independently verified by Intertek.
Top quality clear Canadian Hemlock inside and out reflects golden light in a warm, comforting glow. On Hallmark and InfraSauna rooms the exterior is protected with a biodegradable finish for a luxurious look and ease of maintenance.
Every Finnleo sauna room includes an all-glass door with hardware. NorthStar and Euro saunas use bronze-tinted glass, and where room size allows they add bronze-tinted insulated sidelite windows.
The laser etched door handle doubles as a towel bar on the exterior. On S-Series infrared rooms the interior side of the handle features a slot to hold a mobile device.
Backrests carry integrated low-voltage LED lighting with the RGBW color light therapy system. Hallmark rooms use a 6-bar backrest, NorthStar and Euro a 2-bar backrest, and the Designer saunas vary by model — Centurion a 2-bar wide, Solace a 3-bar, Twilight a 5-bar with bench skirts.
Hallmark and InfraSauna rooms include a built-in floor with vinyl surface, which makes cleaning and maintenance a breeze. The integral floor with waterproof surface is standard on the NorthStar 44 and on all NorthStar Outdoor saunas, and is available as an option on the other NorthStar indoor models and on Vita II.
Every traditional Finnleo sauna ships with a bucket and ladle so you can throw water on the rocks and enjoy löyly from the first session.
