Rounded Olivine Diabase Sauna Stones 3–5 cm (15 kg) are premium-quality natural sauna stones designed specifically for sauna heaters that require smaller stones. Their rounded shape promotes gentle, long-lasting löyly by allowing water to flow evenly over the heated stones.

These 3–5 cm olivine diabase stones are the recommended size for HUUM Cliff, Cliff Mini, Steel, and Steel Mini sauna heaters. The smaller stones fit efficiently between the heating elements while maintaining good airflow for fast, even heating and optimal heater performance.

Made from durable olivine diabase, these stones offer excellent heat retention and are highly resistant to repeated heating and cooling cycles. Each 15 kg box contains carefully selected natural stones. Refer to your heater’s manual to determine how many boxes are required for the recommended stone capacity.
