Finnleo introduced its B-series in 2006. With its superb design combined with Finnleo’s unique CarbonFlex technology and best body coverage, the B-series established a new standard in IR sauna design and performance—and it truly changed the industry. Though competitors try to copy the B-series design, it simply cannot be duplicated. By popular demand by those who prefer a more traditional look, Finnleo proudly continues to offer the “industry classic” B—but with its state-of-the-art Pure Infra Low EMR/Low EF technology.
