Harvia Sauna Stones 5–10 cm — 20 kg Box (AC3000)

Official Harvia sauna heater stones in the small 5–10 cm size — the right stones for Harvia electric heaters including the Cilindro PC70 and PC90 range. Quarried olivine dolerite, chosen for heat storage, durability and clean, safe use at sauna temperatures.

Why proper sauna stones matter

• Heat storage — dense stone holds heat and gives soft, even löyly when you throw water
• Safety — only officially designated sauna stones should ever be used in a heater; ordinary garden stone can crack or spit at temperature
• The right size — 5–10 cm is the correct grade for Harvia electric heaters

How many boxes do I need?

• Harvia Cilindro PC70 — approx. 90 kg (5 boxes)
• Harvia Cilindro PC90 / PC90XE / PC90XW — approx. 80 kg (4 boxes)
• Wall-mounted Harvia heaters (e.g. Vega) — typically 20–25 kg (1–2 boxes)

Stones should be rinsed before first use and stacked loosely so air can circulate — full instructions come with your heater. Replace sauna stones roughly once a year with heavy use.
