6-8 Person Sauna

6-8 Person Sauna

This 6-8 person edition is heated with an 8 kW SAWO heater, with dimensions of 1.8 m x 2.4 m. 


We use New Zealand grown Radiata that has been thermally modified in NZ, producing a timber that excels in the harsh conditions of a sauna. With internal and external Magnum Board wall lining, sheeps wool insulation actively keeps the walls dry, while local Douglas Fir maintains structural integrity.


Shipping included of fully finished sauna to nearest Mainfrieght depot. Hiab from depot is organised by buyer.


All saunas require installation of electric heater by an electrician.Heaters run on single phase supply.

  • Terms of Service

    We offer a Limited Liability Waranty on our saunas. The heater comes with a 3 year warrantly while the owner is responsible for the maintenance of the sauna.

  • Durability

    Our saunas are built to the NZ building code. Unlike imported saunas, our locally crafted units are designed to endure the harsh sun, wind, and rain of the NZ outdoors. Without using any plastics or chemical treatment, our saunas are built by licensed builders to the NZ building code, creating one of NZ's most durable saunas.

  • Plastics

    The building industry is one of the top consumers of plastic, and since fossil fuels are used to create plastic, this is not good news for the climate. Plastics are used in insulation, roofing, windows and doors.. the list goes on. Even building paper is made of plastic, believe it or not. So we are doing our part by building our saunas completely plastic free, while still adhering to the building code to provide you with a high quality, durable product that will last.

  • Chromated Copper Arsenate (CCA)

    Chromated Copper Arsenate (CCA) is banned in Europe, Australia and the United Sates. However, CCA is still used to treat a lot of timbers in NZ. Due to its carcinogenicity and environment toxicity, we choose not to include it anywhere in our saunas. Our thermally modified NZ timber cladding has a hazard rating of H3.2 from the thermal modification alone, while our our Magnesium Oxide flooring replaces typical CCA treated plywood.

  • Timber

    Cedar and Spruce are two great timbers to use inside a sauna. However, the trees grow too quickly in NZ, so this timber is imported from Canada, the US and Scandinavia. At Sustainable Saunas we are doing our best to minimise our carbon footprint, so we use a thermally modified NZ timber. During its thermal modification process it transforms into one of the best timbers you can use in a sauna and gains a wonderful scent similar to cedar.
