Founded in 2014, Saunum is an Estonian-based company dedicated to revolutionizing the sauna experience by addressing a common issue: uneven sauna temperatures. We've all experienced the frustration of a sauna where the temperature isn't consistent—your head feels too hot, your back just right, and your feet are cold. This uneven heat distribution can significantly detract from the relaxation and health benefits that saunas are meant to provide.

Saunum solves this problem with its innovative air-blending technology. This patented system takes in hot air from the upper levels and cooler air from the lower levels of the room, mixing them to release perfectly balanced heat with oxygen-enriched steam. This ensures an optimal temperature throughout the sauna, providing a warming experience from head to toe while making it easier to breathe.

Saunum's heaters are suitable for both commercial and private settings and are compatible with traditional and infrared saunas. Additionally, the Saunum Base offers advanced climate control for both wood-burning and electric saunas, providing consistent steam and gentle heat that enhances skin rejuvenation, respiratory function, and cardiovascular health. The inclusion of Himalayan salt balls in some models adds an extra layer of wellness benefits.

Saunum's Product Offerings

Saunum offers a range of products designed to cater to various sauna preferences and styles. From the modern AirCube series to the classic designs, each product is crafted for maximum durability and year-round use. Saunum also provides control panels for customizing your sauna experience and wellness add-on kits with soothing sauna oils and other accessories to enhance your relaxation.
