Thermo-Aspen interior
Interior cladding, sauna bench, backrest, bench skirt and wooden floor mat all use pale, heat-treated Thermo-Aspen.
Included
The Classic Mini brings Saunum's full outdoor-cabin construction into a 1.86 × 2.1 m footprint. It seats two in comfort or three at classic sauna closeness.
The fixed cabin package includes black Thermo-pine outside, Thermo-Aspen throughout the room, clear 8 mm tempered glazing, dimmable LEDs, Bluetooth speakers, drainage, ventilation, rainwater system and protective OSB transport box. Order it cabin-only or add one of four Saunum heater sets in the customiser.

The Classic Mini arrives as a coherent fixed package, without a trail of paid finishing upgrades.
Interior cladding, sauna bench, backrest, bench skirt and wooden floor mat all use pale, heat-treated Thermo-Aspen.
IncludedLED strips behind the backrest and beneath the upper bench give the compact room depth without harsh overhead glare.
IncludedIntegrated speakers let you play audio without carrying a separate speaker into the sauna room.
IncludedThe exterior is finished in black Thermo-pine with hidden fasteners for a clean, quiet architectural face.
IncludedClear 8 mm tempered glass keeps the front visually open while the compact dark shell sits discreetly in the garden.
IncludedFloor drain, electrical box, ventilation and rainwater system are already built in, so there's nothing extra to source or fit once the cabin's on site — just the final electrician's connection. The assembled cabin travels protected in an OSB transport box.
Included
Thermo-Aspen runs across the walls, bench, backrest, skirt and floor mat, so the cabin reads as one warm timber interior. The glass front brings in the garden, while the layered LEDs make evening sessions feel calm rather than cramped.
Add a Saunum heater and its patented system blends hot ceiling air with cooler floor-level air, creating a more even sauna climate from head to toe.
The cabin can be ordered without a heater. If you add one, choose 6 or 9 kW in either the Experience or Spa Session design; every set includes stones and the complete WiFi-enabled Saunum Leil control system.
The clear glazed front brings daylight into the room and makes the 1.86 m depth feel more open. Black frames and exterior cladding keep the structure visually compact.
Inside, the pale Thermo-Aspen and warm LED lines create a deliberate contrast with the dark shell. The result is a small cabin that still feels like a finished piece of garden architecture.

The Mini is compact for a sauna, but it still arrives as a large assembled cabin in protective packaging.
Prepare a level, stable and well-drained base at least 75 mm above the surrounding ground. Every base beam needs continuous, load-bearing support.
The cabin weighs approximately 1,000 kg and 1,150 kg in its OSB transport box. Plan a suitable forklift, HIAB or crane for unloading and positioning.
Internal electrical work is completed at the factory and a 5-pin 16 A CEE plug is provided. A qualified electrician must confirm the site supply and connect the cabin and any heater.
The narrow rectangular shell works beside a house, pool or garden room, while the warm interior remains visible through the clear front.
Use the customiser above to add a 6 or 9 kW Saunum heater, or leave it unselected for the cabin on its own. Request an installation quote before ordering if you need help with access, positioning or commissioning.

The cabin arrives assembled in protective OSB packaging. Mechanical unloading, positioning and final on-site assembly and electrical connections are not included.

The Sauna of the Next Century
Saunum’s patented air-blending system traps the scorching steam, that rises under the ceiling of the sauna room, mixes it with cooler air on the floor surface, and directs the soft steam back evenly. This ensures a more even temperature of the steam, and the oxygen-enriched steam makes it easier to breathe. Water can be thrown more often to produce more steam, making the sauna air more humid, and ensuring more intense sweat. With Saunum’s patented method of enriching the air with salt ions, the salt ions from the natural salt spheres added to the sauna climate device are infused into the circulating air to reach the skin and respiratory tract. An even more relaxing sauna experience is created with the help of the aroma system, which mixes sauna oil aromas with the steam. It is a healthy alternative to burning aromatic oil on hot stones.
