Thoughtful craftsmanship The Leil Sauna Viva 250 is crafted in Estonia using 1.57” (40 mm) ThermoWood® walls, which are built for outdoor performance and steady heat retention. Inside, thermo-alder benches and backrests feel smooth in humid conditions and hold up beautifully over time. The fit and finish is the kind you notice in the quiet details, from the clean front wall styling to the hardware choices on the glass. 
 Comfort-driven design Added height makes the sauna feel lighter and less boxed-in, especially for groups. The interior width gives you room to settle in without bumping knees, and the bronze-tempered glass front creates a warm, inviting glow without putting you on display. Optional under-bench and backrest LED lighting gives the room a softer mood when you want that spa feel at home. 
 Performance you can feel Three integrated ventilation openings support smoother airflow, oxygen-rich sessions, and more consistent heat. The Viva 250 is also compatible with both electric and wood-fired heaters, so you can build your setup around the kind of heat ritual you prefer. If you want a stronger steam presence, pairing the unit with a properly sized HUUM heater package helps the room perform at its best. 
 Built for long-term use ThermoWood® is naturally durable and well-suited for changing seasons. With proper installation over a flat, load-bearing surface and basic care (venting out after use), the Viva 250 is built to stay sharp, stable, and enjoyable for the long haul.
