Hot Box Outdoor Sauna
The Hot Box saunas are unique in their shape. The huge glass panel allows views of the stars at night, sunset or sunrise, or just watch the world go by.
The Hot Box is very effective and efficient. There is less wasted space to heat, and the curved sides allow the heat to circulate efficiently as new heat rises from the heater. The reduction in wasted space allows the space to heat up in less time and with excellent insulation the outside surface of the sauna will stay cool to the touch.
Our Hot Box is very low on maintenance, with the Thermowood being naturally resistant to water and insects, and it’s strength allows it to handle even a heavy snow fall. The integrity of the structure ensures that the sauna is able to withstand all outdoor elements. The construction of The Hot Box allows the wood to expand and contract without any distortion while also maintaining the seals for a lifetime.
The Hot Box is available as a two-person, four-person or six-person model, making it a perfect place to relax and enjoy time with family and friends, and is an ideal addition to a sociable outdoor space.
