HUUM Replacement Stones
HUUM Replacement Stones

The HUUM 1.2-2 inch rounded olivine diabase sauna stones are purpose-selected for maintaining the high-performance heating and signature aesthetic of modern sauna units. We provide these small replacement stones in a 33-pound box to allow for a dense, tight pack in the heater basket, which minimizes gaps and promotes even airflow for smooth, consistent steam. This specific size is the right solution for refreshing heaters where original stones have fractured, as the 1.2-2 inch diameter ensures a gentle and enveloping sauna climate without stressing the heating elements. By utilizing high-density volcanic rock with rounded contours, we ensure these stones deliver reliable heat retention while providing a natural, sculpted look that suits any modern or traditional residential interior.

  • Heat-storing olivine diabase – Crafted from dense olivine diabase that tolerates repeated high-temperature cycles, these stones store and release heat gradually, creating a smoother, more stable löyly rather than short, harsh bursts of steam.
  • Gentle, controlled steam – Rounded surfaces and high heat capacity support softer steam when you ladle water, helping you fine-tune humidity and temperature for a more comfortable, enveloping sauna climate that suits extended, relaxing sessions.
  • Optimized small stone sizing – Sized roughly 2″–4″, the stones can be packed tightly with minimal gaps, promoting even airflow through the heater basket and more uniform heat distribution from top to bottom of the HUUM unit.
  • Durable, fracture-resistant set – Selected for structural integrity, the stones resist cracking and glazing under repeated heating and cooling, helping maintain efficient heater performance and reducing the frequency of stone replacement over time.
  • Tailored for HUUM heaters – The rounded, sculpted shapes complement HUUM’s open-basket design language, preserving the heater’s distinctive aesthetic while delivering the consistent thermal performance the heater’s engineering requires.
