Saunum’s patented air blending system draws heat and steam from near the ceiling, mixes it with cooler, more oxygenated air near the floor, then directs more comfortable, breathable steam throughout the room. This equalizes room temperature by more than 60% for a significantly better sauna experience. You’ll enjoy longer, more satisfying sauna sessions with more intense sweating.
All sauna bathers have experienced the same issue, extreme variance in temperature and oxygen from the ceiling to the floor. The temperature at the ceiling can often exceed 200°F, while at the floor it will be under 100°F, causing your feet to feel uncomfortably cool and your head to be too hot. The temperature and oxygen level should be more consistent throughout.
This revolutionary sauna heater includes an ingenious climate equalizing system that more evenly balances the temperature and oxygen levels throughout your sauna for softer, more breathable air.
Saunum is all about the air!
- The AIR we heat
- The AIR we feel
- The AIR we breathe
Enrich the air with Himalayan salt ions
The ions released from the patented Himalayan salt feature are propelled into the sauna to maximize their health benefits. Salt aerosol has long been used for its benefits as a decongestant, inflammation reduction, and possesses anti-microbial properties.
Add another dimension to your sauna with aromatherapy
Breathe deep, relax, let the room fill with heat and steam, and clear away your tension with the invigorating and awakening scents of Saunum’s available aromatherapy option.
Experience 6 distinct styles of sauna bathing
Saunum lets you customize your bathing experience by adjusting airflow, temperature, and steam to suit your exact preferences.
- Russian Banya – Air blending, massive stone volume, intense heat, and steam. Heat, ventilation, and humidity merge to simulate a traditional banya.
- Finnish Sauna – Harness the power of intense, dry heat for an authentic Finnish sauna. Its huge rock mass radiates intense, consistent heat.
- Estonian Sauna – Long sweats, soothing heat and rich steam are the hallmarks of an Estonian sauna.
- Yoga Sauna – Oxygenated airflow allows for yoga sauna experience. Even at floor level, equalized Air delivers warming heat for ideal hot yoga sessions.
- Salt Sauna – A patented system propels healthful Himalayan salt ions throughout the room. Air passes across the salt chamber creating a true salt sauna.
- Aroma Sauna – Not possible in most saunas, Saunum uses high humidity and air movement to bring satisfying aroma to your experience.
- Air Mixing Technology: Saunum’s patented air blending system mixes cold, oxygen-rich air from the floor with hot, oxygen-poor air from the ceiling to eliminate the discomfort commonly associated with traditional saunas. Whether you prefer an extremely hot sauna or a more gentle warmth, this system ensures consistent heat and oxygen distribution from head to toe.
- European Design: Sleek Scandinavian design with high-quality materials. Available in two elegant finishes—black or stainless steel. The only difference between the two models is the exterior finish.
- Massive Stone Capacity: Features a large 132 lb stone capacity (requires 4 boxes of stones, sold separately). A greater quantity of stones results in softer, more even heat and more luxurious steam.
- Himalayan Salt Reservoir: Built-in Himalayan salt spheres are positioned within the air stream, allowing salt ions to circulate throughout the sauna for added health benefits.
- Water-Tossing Friendly: Saunum is engineered to handle water being tossed onto the rocks for an authentic sauna experience. After use, the patented fan system helps dry the sauna efficiently.
- UL Certification: Built to exceed strict UL safety and reliability standards.
- Optional Aromatherapy: Enhance your sauna session with Saunum’s optional aromatherapy system, which infuses aroma into the steam for a deeper sensory experience.
- Sauna Room Size Compatibility: Suitable for sauna rooms ranging from 106 to 212 cubic feet.
