Our UNION 3–5 person sauna comes as a preassembled kit for easy setup. Made from 42mm thick thermotreated spruce, it’s engineered for excellent heat retention and durability. Inside, you’ll find premium split-level benches made of knotless Thermo Aspen for both comfort and style.
When you choose the UNION 3–5 person model, everything you need comes in the box:
The UNION Sauna 3–5 person model uses the same proven stave assembly method as its smaller sibling. Precision-cut staves interlock to form a solid, airtight cabin, while a subtle roof curvature ensures rainwater runs off easily, keeping your sauna dry and weatherproof.
Functional, modern, and beautifully crafted, your backyard just got an upgrade.
With 42mm thick thermotreated spruce, the 3–5 person sauna heats quickly and maintains steady warmth throughout. 8mm bronze-tinted glass adds a refined aesthetic while offering privacy and soft natural light, the perfect setting for deep relaxation.
Choose your perfect position, high bench for an intense sweat, or lower for a gentle session. The curved, ergonomic Thermo Aspen benches provide lasting comfort and elegant simplicity for every sauna experience.
Every UNION 3–5 person sauna is crafted from sustainably sourced Nordic Spruce and fitted with premium knotless Thermo Aspen benches. It’s a natural, breathable, and long-lasting build that looks stunning in any setting.
Eco-friendly, stable, non-toxic wood that delivers natural durability and beauty.
Premium seating with ergonomic comfort for up to 5 people.
42mm stave boards for consistent warmth and minimal energy loss.
