RecoSauna Sisu Square Sauna in Thermowood: Modern Scandinavian Sauna Living
RecoSauna Sisu Square Sauna in Thermowood blends modern Scandinavian architecture with a rich natural timber finish for a sauna that feels as considered as the space around it.
Its open glass frontage creates a brighter, more connected atmosphere, while the 2 to 6 person interior makes it equally suited to quiet solo recovery and shared sauna evenings. Built with a 46 mm solid-wood wall structure, the design combines natural materials with clean lines for a sauna that feels substantial, warm and timeless.
Modern Scandinavian Sauna Design
The Square Sauna collection is designed around a simple idea: make authentic sauna bathing feel at home in contemporary spaces. Tempered tinted glass across the front brings in natural light and creates a more open feeling, while the square silhouette gives the sauna a refined architectural presence.

Inside, a Straight Black Alder or Aspen sauna bench creates a comfortable place to settle into the heat. The sauna can be paired with electric or wood-burning heating, giving you flexibility to shape the experience around your preferred sauna ritual. The heater is sold separately.
