Rounded Olivine Diabase Sauna Stones 5–10 cm (15 kg) are premium-quality natural sauna stones designed to produce soft, long-lasting löyly while providing excellent heat storage and durability. Their rounded shape allows water to flow smoothly over the stones, creating gentle, even steam for a comfortable sauna experience.

These 5–10 cm olivine diabase stones are ideal for larger sauna heaters, including HUUM DROP, HIVE Mini, HIVE, and HIVE Wood models, as well as other sauna heaters that specify 5–10 cm stones. Their larger size promotes proper airflow and efficient heat distribution throughout the stone compartment.

Made from durable olivine diabase, these stones are engineered to withstand repeated heating and cooling cycles. Each 15 kg box contains carefully selected natural stones. Refer to your heater’s manual to determine the total amount of stone required.
