Why the MW20 Is the Ultimate Backyard Sauna for Groups
European Craftsmanship
The MW20 is built from genuine Scandinavian thermowood — a heat-treated timber that resists moisture, rot, and weathering far better than standard wood. This European engineering tradition ensures the sauna maintains its structural integrity and refined appearance season after season, even in demanding outdoor climates.
Spacious Group Wellness
Designed to comfortably seat 5–6 adults, the MW20 transforms your backyard into a genuine social wellness destination. Whether sharing post-workout recovery sessions with friends or hosting a weekend sauna ritual with family, this sauna provides the space and comfort that smaller units simply cannot match.
Flexible Heater Options
The MW20 supports three distinct heater configurations — the traditional Harvia M3 wood-burning stove, the reliable Harvia Kip 8.0kW electric heater, or a WiFi-enabled electric heater for remote control and scheduling. Choose the experience that best suits your lifestyle, and upgrade at any time.
Flat-Pack Delivery — Engineered for Efficient Assembly
The MW20 ships flat-packed in its original packaging, allowing for safe freight transport and organized on-site assembly. Each component is precision-cut and clearly labeled. Assembly, site preparation, and electrical hookup are the buyer's responsibility unless separately arranged. A licensed electrician is required for electric heater installations.
Installation
Site preparation and a suitable foundation are required before assembly begins
Prepare Your Site
Place the sauna on a level concrete pad, patio pavers, or reinforced deck for a stable, long-lasting foundation
Electrical Setup
A licensed electrician is required for all electric heater hookups — plan your electrical access in advance
Wood-Burning Note
Wood-burning heater installations require a chimney set and professional installation. Check local fire regulations before selecting this option
Assembly, site preparation, ventilation (for wood-burning), and electrical hookup (for electric heaters) are the buyer's responsibility unless separately arranged. Heater, chimney set, controls, and installation services are not included with the sauna cabin purchase.
