Rounded Olivine Diabase Sauna Heater Stones — 5–10cm, 20kg
Good löyly starts with good stones and rounded olivine diabase brings a softer, more refined take on the classic sauna rock. Just as durable and heat-retentive as split-faced stone, the smooth river-stone shape gives a gentler steam and a more natural, spa-like look inside your heater. Sourced from volcanic rock and packed in a 20kg box at 5–10cm.
Why you'll love it:
- Softer, Gentler Steam: The rounded shape encourages water to flow smoothly across the stones, producing a milder, more relaxing löyly compared to sharper, angular rock.
- Superior Heat Retention: Olivine diabase's density gives excellent thermal conductivity, so your heater warms efficiently and holds temperature consistently.
- Resists Thermal Shock: Handles the constant cycle of intense heat and sudden cooling from water without crumbling or breaking down like lower-grade rock.
- Better Airflow: The smooth, rounded contours create natural air channels through the heater bed, helping electric and wood-fired units heat evenly.
- A More Natural Aesthetic: Rounded, river-stone styling gives a softer, more organic look than traditional angular stones — a nice finishing layer over your existing bed.
- Volcanic Origin: A naturally occurring volcanic stone, chosen specifically for its density and durability under sauna conditions.
What's included: One 20kg box of rounded olivine diabase sauna stones, 5–10cm.
