These premium Finnish stones are hand-selected for quality and safety, offering a softer approach to steam generation that transforms your sauna ritual.\u003c\/p\u003e\n\u003ch3\u003eSofter Steam, Better Experience\u003c\/h3\u003e\n\u003cp\u003eUnlike angular stones that release steam quickly, rounded olivine diabase stones allow water to cascade gently down through the layers. This unique flow pattern reaches more stone surface area, generating a greater volume of steam with a noticeably softer, more pleasant touch on your skin. The result is a more luxurious löyly—the Finnish term for the steam that defines authentic sauna bathing.\u003c\/p\u003e\n\u003ch3\u003ePremium Olivine Diabase Quality\u003c\/h3\u003e\n\u003cp\u003eThese stones are crafted from olivine diabase, one of the most durable and heat-resistant materials approved for sauna use. The gray-green olivine coloring adds an elegant, natural aesthetic to your heater while providing excellent thermal mass for consistent heat distribution. Each stone is inspected to ensure it's clean, safe, and free of harmful ingredients.\u003c\/p\u003e\n\u003ch3\u003eProper Installation for Best Results\u003c\/h3\u003e\n\u003cp\u003eRounded stones work best as a top layer over angular stones. For optimal performance, use same-sized angular stones (like Harvia AC3000) in the bottom layers of your heater—they provide more heating surface area for water contact. Place the rounded stones loosely on top, allowing proper air circulation for longer heater life and better steam production. This layering technique works in all compatible Harvia sauna heaters.\u003c\/p\u003e\n\u003ch3\u003eCompatible Heaters\u003c\/h3\u003e\n\u003cp\u003eThese 5-10cm rounded stones work with Harvia heaters designed for smaller stone sizes, including the Cilindro series, Club series, KIP series, Vega series, TopClass series, The Wall series, Spirit series, and Virta Pro models (HL160E, HL200E). Each 33-pound box contains enough stones for a generous top layer. We recommend purchasing an extra box to allow selection of the best-fitting stones for your specific heater configuration.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003ch3\u003eStone Quality\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Olivine Diabase\u003c\/strong\u003e — one of the most durable materials approved for sauna heaters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand-Selected Stones\u003c\/strong\u003e — inspected for safety and quality before packaging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Harmful Ingredients\u003c\/strong\u003e — clean, natural stones safe for high-heat use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSteam Performance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSofter Steam Generation\u003c\/strong\u003e — rounded shape allows water to cascade through layers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGreater Steam Volume\u003c\/strong\u003e — more surface contact produces more löyly per pour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved Air Circulation\u003c\/strong\u003e — loose piling extends heater element life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDesign \u0026amp;
