Sauflex Jadeite Sauna Stones — 10–15 cm, 15 kg crushed (per bag)

Jadeite is prized in Finnish saunas for one simple reason: it holds heat like almost nothing else. Denser than the more common olivine diabase, a bag of jadeite stones will keep a stove throwing out radiant warmth long after the elements have switched off — and gives you that silky, soft löyly when you throw water over them.

These are the 10–15 cm crushed stones— angular, irregular faces that pack tightly around your heater and radiate strongly from every side. A 15 kg bag typically dresses a mid-sized electric or wood-burning stove.
