Harvia is a Finnish sauna heater and sauna maker founded in 1950, headquartered in Muurame, Finland. It has been publicly listed on Nasdaq Helsinki since 2018, and Harvia states it manufactures more than 150,000 heaters a year, shipped to more than 80 countries. In 2018, Harvia acquired Almost Heaven Saunas, the West Virginia sauna builder founded in 1978, adding US manufacturing to its Finnish base.

That scale shows up in the hardware. The heaters in this catalog, the KIP, the Wall, and the Spirit, use Harvia's own stone chambers, heating elements, and Xenio or Fenix WiFi controls rather than third-party parts, the same core platform many other sauna brands build their cabins around.

Ellara carries Harvia for that reason: a genuine industry-standard heater, sold here on its own for a new build, a replacement, or an upgrade.
