Steam is generated by pouring water on the sauna stones. You can simply take a wooden bucket, fill it up with water and place it inside the water. The water should be warm, otherwise, it will cool off the stones. Scoop some water from the bucket with a ladle and pour it one the sauna stones. Use this method for electric and wood-burning heaters. We also offer an alternative solution for wood-burning heaters – a stainless steel water tank that attaches to the chimney. The heat from the chimney warms the water, thus it will not cool of the sauna stones.
