The Nordhaus 4-6 Person Traditional Sauna is built from premium Canadian hemlock and powered by a 6kW electric heater, delivering the high, dry heat associated with traditional Finnish-style sauna bathing.
Dual-tier benches seat up to six people, with sauna stones included so you can pour water over them to generate steam (löyly) and adjust humidity during a session.
Canadian hemlock is widely used in sauna construction for its low resin content, resistance to warping under sustained heat, and light, tight grain.
Suited to households or shared spaces wanting a full-size, authentic traditional sauna with room for family or guests, supporting relaxation, circulation, and post-workout recovery.
