Description

The SaunaLife Model S4N is a wood-fired soaking vessel engineered for rapid thermal performance and operational efficiency. This six-person SOAK-Series unit features a fiberglass basin with ergonomic contours and a durable spruce exterior, arriving pre-assembled for immediate installation. Its corrugated firebox incorporates a secondary heat-recovery chamber that minimizes wood consumption by approximately 50% while achieving 40°F-to-95°F heating in 1.5 to 2 hours—industry-leading speed for wood-fired systems. Dual-channel circulation ensures uniform temperature distribution, while superheated air trapped between the fiberglass and exterior wood layers amplifies heating efficiency. The design requires no electrical infrastructure. Built in Northern Europe with meticulous attention to thermal dynamics, the Model S4N balances quick warm-up capability with sustained fuel economy for year-round outdoor use.
