Harvia Stones for Virta, M3 and Pro 20 Wood Burning Stoves, and Harvia Legend Models

Crafted according to traditional Finnish standards, genuine Harvia sauna granite stones (4" - 6") are designed to deliver consistent, balanced heat and an authentic sauna experience. These angular, split-face stones are specifically engineered for electric heaters and wood-burning stoves. Their fractured surface increases surface area, allowing water to evaporate efficiently and produce a softer, more even steam.

Why Split-Face Stones Matter:

• Superior Heat Retention — Stores high temperatures for consistent performance
• Efficient Steam Production — Fractured surfaces enhance water evaporation
• Improved Airflow — Angular shape allows loose stacking, promoting proper circulation
• Extends Heater Lifespan — Better airflow helps reduce strain on heating elements
