Finnmark Combination Barrel Sauna FD-6

The FD-6 is the first 4-person hybrid barrel sauna engineered for both deep-penetrating infrared and traditional steam heat — in one precision-built Western Red Cedar cabin. Designed for residential use indoors or outdoors under cover, this model merges UL-listed Spectrum Plus™ near-infrared, 360° carbon far-infrared, and an optional 4.5kW traditional rock stove, offering unmatched flexibility for daily recovery, detox, and relaxation.

 

Built from 1.5-inch thick clear cedar staves, the FD-6 delivers superior insulation and durability. Its spacious barrel shape comfortably seats four adults, while the dual-tier benches, tempered glass door and windows, red light therapy system, and WiFi-connected touchscreen controls provide a spa-grade experience without hardwiring the infrared system. With plug-and-play infrared operation on 120V, a weather-resistant design, and an optional steam upgrade, the FD-6 is the most versatile, full-spectrum barrel sauna available.
