Ravn M - Modern Sauna

The RAVN M Outdoor Sauna is a compact Scandinavian-crafted sauna designed for homeowners who want a modern outdoor retreat without sacrificing too much space. Built with a clean, box-style silhouette and sized comfortably for 3 to 4 bathers, the RAVN M combines contemporary design, efficient performance, and premium materials in a format that works beautifully in modern backyards and urban outdoor settings.

More than just a compact sauna, the RAVN M is designed to deliver an authentic sauna experience in a highly functional footprint. From its durable Thermowood construction to its bright glass front and comfortable multi-level benching, every element is thoughtfully designed for everyday use and long-term enjoyment.

Modern Scandinavian Design in a Compact Footprint

With its clean lines and minimal architectural profile, the RAVN M is a refined take on the traditional outdoor sauna. Its modern Scandinavian appearance makes it an ideal fit for contemporary homes, while its compact dimensions allow it to integrate easily into smaller outdoor spaces without compromising the overall sauna experience.

Thermowood Construction for Durability and Stability

Crafted from Scandinavian Thermowood®, the RAVN M is built for durability, efficiency, and long-term performance. Thermowood is created by heat-treating Scandinavian softwood at temperatures between 180–230°C in special kiln chambers for up to 96 hours, using steam as a protective gas during the process.

This treatment improves the wood in several important ways. Thermowood is more dimensionally stable than untreated timber, meaning it is less likely to swell, crack, shrink, or react dramatically to changing humidity levels. It also does not secrete sap or resin in high heat. The process also improves resistance to rot and fungi, enhances insulation performance, and extends the lifespan of the wood — all while remaining environmentally friendly, as it is produced without chemicals using timber sourced from well-managed, PEFC-certified forests.

Built for Heat Retention and Weather Protection

The RAVN M features 42 mm (1.65") thick solid wood walls, providing excellent structural stability and reliable heat retention for a consistent sauna session. The roof is designed for outdoor durability and is compatible with PVC / EPDM roofing for dependable weather protection. Roofing is available as an add-on, or customers may choose to apply their own preferred waterproofing solution.

Comfortable Interior with Multi-Level Benching

Despite its efficient footprint, the RAVN M offers an interior volume of approximately 4.9 m³ (173 ft³), creating a surprisingly spacious feel inside. The interior is designed with multi-level benching to help bathers enjoy different heat zones, while the 450 mm (17.7") upper bench provides a comfortable platform for full-body relaxation. A lower step makes access to the upper bench simple and practical.

The large glazed front and tempered glass door bring natural light into the sauna, helping the interior feel more open while maintaining a sleek, premium appearance. The door measures 192 × 69 cm (75.6" × 27.2"), adding to the sauna’s bright and inviting feel.

Designed for Easy Delivery and DIY Assembly

The RAVN M Outdoor Sauna is supplied as a complete DIY sauna kit, making it easier to transport, handle, and assemble on site. With a net weight of approximately 550 kg (1,210 lbs) and compact packaging dimensions of 2350 × 1200 × 750 mm (92.5" × 47.2" × 29.5"), it is designed for efficient shipping while still delivering a premium sauna structure once installed.
