The S820 is Finnleo's popular two-person infrared model: a 13.3 sq ft hemlock cabin with the brand's Pure Infra low-EMR/low-EF design, color light therapy, and Bluetooth audio, all on a standard 120V outlet. The trade-off is the dealer model — Finnleo publishes no price, no max temperature, and no warranty terms online, so you have to get a local quote to compare it against DTC rivals.

Finnleo positions the S820 as one of its most popular infrared models, and the published spec sheet explains why: it seats two in a footprint of only 13.3 square feet, plugs into a standard 15-amp 120V outlet, and carries the S-Series feature set — Pure Infra low-EMR/low-EF panels, an all-glass front wall, in-backrest low-voltage lighting with a color therapy system, valance and bench-skirt lighting, and a Bluetooth sound system. The cabin measures 47-3/4" W x 40" D x 76-1/2" H and is built in hemlock inside and out, and Finnleo suggests it slots into a home gym or even a bedroom.
What the official page does not tell you matters just as much. Finnleo sells exclusively through its dealer network, so there is no published price — the figure listed here is an approximate market price, and your quote will vary with delivery and installation. The page also omits heater wattage, maximum temperature, and warranty terms, which makes head-to-head comparison with direct-to-consumer infrared brands harder. What you are buying instead is the backing of the largest US sauna manufacturer, a division of Sauna360 building in Cokato, Minnesota since 1984, with local dealer support before and after the sale.
