The Almost Heaven Seneca Barrel Sauna is built for comfort, space, and authentic sauna experiences—right in your backyard or home. Measuring a spacious 7’x7’, it’s a full foot wider than standard barrel saunas, giving you extra room to stretch out or comfortably seat up to six people.

Designed for both indoor and outdoor use, the Seneca comes standard with a Harvia 8kW electric heater that delivers temperatures of up to 180ºF. Prefer a rustic touch? Upgrade to the Harvia M3 wood-burning stove for a traditional, off-grid sauna experience. With the electric model, you can start heating immediately or delay the start time by up to 8 hours—optionally controlled via Wi-Fi.
