A climate device for a sauna with a wood-burning or electric heater. Saunum Base solves the main problems of modern steam saunas that use classic wood-burning or electric heaters, such as temperature stratification, brief yet scorching steam, and low breathability. The unique Saunum Base sauna climate device, which complements the heater, fits in every sauna, ensuring a more even temperature with a softer and more airy steam. Himalayan salt balls and the unique features of the device make each sauna a relaxing spa experience.
