A portable sauna is made of western red cedar that is naturally rot resistant and antimicrobial. The Surf Sauna is built to accommodate two to eight people and although it's built for winter surfers, it can be used for other activities beyond surfing. The hardware and chassis are made from galvanized and stainless steel, according to the New Hampshire-based company.
A rectangular window higher up on the wall of the front of this outdoor sauna acts as a transom window to bring in light and give some definition to the outdoor room. Glenn Auerbach, a Minnesota sauna builder who blogs at SaunaTimes.com, also says a transom gives people using the sauna a panoramic view.
Cedar tongue and groove is used throughout this sauna. The "candle window" is an extra feature that Glenn Auerbach, an outdoor sauna builder who operates SaunaTimes.com, says can create a feeling of openness in an outdoor sauna.
Western red cedar is often used for saunas, including those built by Glenn Auerbach in Minnesota. He says in Scandinavia, many saunas are paneled with white spruce. Auerbach advises staying way from pine and if you need to save money, look for recycled cedar to use in an outdoor sauna.
Outdoor saunas can offer health benefits and relaxation as well as serve as a unique spot to socialize with friends and family, according to Glenn Auerbach, a sauna builder who blogs at SaunaTimes.com.
