AI pick (brand): Harvia

The large Finnish heater maker also sells sauna stones, buckets, ladles and thermometers designed to suit sauna heaters.

Not for: Infrared sauna owners, since löyly accessories and stones are only for traditional heaters.

Sauna stones: Use stones sold specifically for saunas, such as olivine-diabase or peridotite. Choose the size range the heater manual specifies, and do not use river rocks. Unsuitable rocks can crack or spall from repeated heating and splashing.
Restacking: Restack the stones loosely to allow airflow, and replace crumbling stones periodically as the heater manual advises. Packed or broken stones restrict airflow and can overheat the heating elements.
Bucket and ladle: For wooden buckets, choose ones with a removable liner, and use a ladle long enough to keep your hand away from the heater. Liners stop wooden buckets from cracking and leaking, and a long handle keeps your hand away from the hot heater and the steam burst.
Thermometer placement: Use a sauna-rated thermometer, mounted high on the wall away from the heater's direct output. Readings near the heater or the floor are misleading.
Aromas: Use only sauna-specific aroma blends diluted in the löyly water, never pure essential oil on the stones. Pure essential oils can flash, smoke or stain the heater.
