Jadeite Sauna Stones – Polished (5–9 cm, 10 kg)

Jadeite gives a sauna heater a deep green colour, and polishing leaves these stones smooth and glossy. It's a dense stone with a non-porous surface that stores heat well. The 5–9 cm size suits electric heaters and wood stoves that take mid-sized stones. Because the pieces are smooth and rounded, read your heater's manual first: some makers, including Harvia for its Legend, call for angular split-face stones. Rinse before use and stack the stones loosely so air can circulate.
