Finnleo Centennial Infrared Saunas
The Finnleo Centennial Infrared line, new for 2026, is a set of indoor far-infrared saunas for 1 to 3 people: the Sentinel 1, 2 and 3. Each model uses Pure Infra emitters with wall-to-wall panels, calf emitters, a floor emitter and an in-bench emitter.
These saunas are built with Okoume wood and an all-glass front wall, and use the SaunaLogic2-IR control panel and app. All three plug into 120V power: 15 amp for the Sentinel 1 and 2, 20 amp for the Sentinel 3.
