Heat comes from Pure Infra Emitters far-infrared emitters, which warm you directly at a lower air temperature than a traditional sauna. It runs on 120V / 20 Amp / 1980 Watts power. The interior is finished in Okoume. Paradise Patio Solutions can walk you through electrical needs, placement and delivery.
