HUUM Replacement Stones 12– Extra Small are crafted to renew the performance and clean visual look of your HUUM sauna heater with compact, rounded olivine pieces. Ranging from 1″ to 2″, these extra-small stones fill upper layers tightly, helping the heater store heat efficiently and release steam smoothly when water is applied. Their dense olivine diabase composition resists fracturing under rapid temperature shifts, ensuring long service life even in frequent sauna use. The rounded shapes support natural airflow through the heater basket, allowing elements to warm evenly while producing the soft, balanced steam HUUM heaters are known for. Ideal for fine-tuning heat distribution or restoring a well-used unit, this 33 lb box provides an authentic set of HUUM sauna stones that enhance durability, responsiveness, and overall bathing comfort.

  • Rounded Olivine Stones – Crafted to withstand extreme heat while delivering a gentler, more comfortable steam, enhancing overall sauna enjoyment and preserving the soft heat characteristic of HUUM heaters.
  • Durable Construction – Made from dense olivine diabase, these stones resist cracking under rapid temperature changes, ensuring long-lasting performance even with frequent sauna use.
  • Optimal Heat Distribution – Extra-small stones (1″–2″) fit tightly in the upper layers, supporting even heating and smooth steam release, helping the sauna maintain balanced warmth throughout sessions.
  • Complements Heater Design – Rounded shapes align with HUUM heater baskets, promoting natural airflow, efficient element heating, and an aesthetically pleasing, polished appearance.
  • Customizable Steam Regulation – Pouring water on these stones allows precise control over steam intensity, enabling users to tailor the sauna experience to personal comfort preferences.
  • Convenient Package – A 33 lb box provides sufficient stones for refreshing or topping off your heater, ensuring consistent performance and easy maintenance of the sauna’s heating surface.
