The 4-6 person Lennon Outdoor Cube Sauna swaps the L-shaped bench for a stacked two-tier layout, so you can choose your heat intensity. The bigger interior seats up to six with room to spread out. Tongue-and-groove cedar, 8mm tempered glass, and a steel roof keep the heat in and the weather out. The PrairieFire 9kW heater is built to preheat fast, while everything you need for a dry or steam sauna comes in the box.
