Hukka Höyrykivet

While traditional sauna stones let the water evaporate on the surface of the bricks, the Hukka Höyrykivet Steam Stones feature 4 small chambers. The 4 holes act as a reservoir and collects approximately 1.35 oz of water and sauna fragrance oils when in use. As the water starts to gradually warm up, the vapors mixed with fragrance oils are evenly evaporated into the air calmly and continuously.
