The Leil Saunas Viva 210 Outdoor Sauna is a spacious 4-person retreat that blends modern design with authentic Nordic craftsmanship. Constructed from 1.57" thick ThermoWood®, it offers superior durability, thermal efficiency, and natural resistance to outdoor conditions, while the smooth Thermo-Alder benches and backrests provide warm, ergonomic seating. Its tempered bronze glass door with black hardware enhances both style and heat retention, and the stave-built ThermoWood® roof with EPDM membrane ensures lasting protection against the elements. Thoughtful ventilation with intake near the heater, exhaust under the benches, and an adjustable upper vent maintains fresh, oxygen-rich airflow and consistent warmth, including at foot level. Additional staves above doors and windows stabilize internal temperatures and minimize steam loss. Compatible with electric or wood-fired heaters, and supporting optional LED lighting or Hexagon DECO panels, the Viva 210 transforms any backyard or terrace into a versatile, premium sauna space ideal for families, couples, or small groups seeking daily wellness and comfort.
