The Thermory No 43 is a premium 4-person square barrel sauna engineered for superior interior volume and high-performance climate resilience. We provide this model as the primary solution for homeowners seeking a private outdoor retreat, featuring thermally modified Nordic spruce that offers exceptional durability and chemical-free rot resistance. This specific model is the right choice for all-weather environments, as its solid back wall maximizes insulation and privacy while the included protective rain jacket ensures long-lasting readiness against the elements. By utilizing a square-barrel design that provides significantly more headroom than traditional circular models, we ensure a spacious environment for up to four people, complete with a built-in front porch for versatile cooling down between sessions. We offer the No 43 as a sophisticated backyard wellness sanctuary that combines modern square aesthetics with precision-engineered wood science for a durable and inviting recovery experience.
