Sun Stream Saunas
Backed by 20+ Years of Infrared
Sauna Expertise




At Sun Stream Saunas, our mission is simple — to bring the safest, most effective infrared saunas to your home, backed by science, integrity, and over 20 years of expertise.
Our story started with a personal health journey. When co-founder Asano faced a major health challenge, we discovered the transformative benefits of infrared sauna therapy. Since then, we’ve been dedicated to helping New Zealanders reduce toxins, relieve pain, and boost energy through premium home infrared saunas.
Founded in 1999, Sun Stream Saunas is one of the original pioneers in the infrared sauna industry. For more than two decades, we’ve led with innovation — introducing ultra-low EMF saunas before they were standard and refining them with our advanced Evolve EHS system for minimal EMF and ELF exposure.
Today, our Evolve 360° Infrared Saunas set the benchmark for home wellness in New Zealand. With full surround heat — even in the glass door — and premium Canadian Hemlock timber, every detail is designed for safety, purity, and superior performance.
From homes across New Zealand to North America and beyond, Sun Stream Saunas have transformed thousands of living spaces into personal wellness sanctuaries. More than just a sauna, it’s a long-term health upgrade for life.

Sun Stream Saunas is known for producing high performing saunas with 360 degree radiant heat coverage and ultra low EMF & ELF heating technology. With over 300 five-star google reviews from New Zealand customers, we are one of the most trusted infrared sauna brands in the country.
We were one of the first companies to incorporate EMF cancellation technology into our Nano Carbon heaters back in 2010. Then in 2019, we took this a step further with the introduction of our Evolve EHS heater and electrical system, which brought EF/ELF electric field mitigation to unprecedented levels in the industry.
Magnetic Fields (EMF) – Near Zero, less than 1mG when measured from a distance of less than 1 inch from the heaters.
Electric Fields (EF/ELF) – Less than 20m/V (Only 2 sauna brands in Australasia mitigate ELF, the majority of other brands exceed 1000+m/V
Infrared saunas are energy efficient making them economical for regular use. For the Sun Stream Evolve Mini approximately $0.35 cents per hour, and for the larger saunas like the Evolve 30 only $0.50 cents per hour. These costs are based on $0.25/kWh tariff from your electricity supplier.
Yes, all Sun Stream saunas include an Invisible fastening system where the panels simply slot together to create a solid connection. Installation is quick, easy and requires only a screwdriver to fix the handle to the door along with a couple of additional minor tasks. Check out our easy assembly manuals.
Click here to learn why a Sun Stream Sauna is hotter than all other brands!
Yes. All Sun Stream models are designed for residential use and are simple to assemble. Most units are plug-and-play and require no special wiring, just a 10Amp power point, making them ideal as a home infrared sauna solution.
An infrared sauna uses advanced infrared panels to warm the body directly, rather than heating the air like a traditional sauna. This allows for a deep, comfortable sweat at lower temperatures, making it ideal for regular home use.
Sun Stream offers models ranging from compact 1-person units to spacious 4-person saunas suitable for families.
Consider available space, number of users and placement location. Our team can help you select the best infrared sauna for your needs and budget.
Yes you can put your sauna outside, however there is strict criteria. All Sun Stream Saunas are made from untreated natural timber and are not designed to withstand exposure to weather. Our warranty does not cover damage caused by exposure to the elements, so the onus is on the customer to keep their sauna protected at all times.
Regular use may support relaxation, improved circulation, detoxification, stress relief, and general wellness. See health benefits.
With good supervision and following the recommended guidelines there really is no age limit to using infrared saunas safely.
With proper use, care and maintenance, our premium saunas are built to last many years, in fact with offer a residential lifetime warranty.
Absolutely. Many customers integrate sauna sessions with cold therapy or other wellness practices including the Solace Ice Bath for a complete recovery and relaxation routine at home.
The main difference is the way the saunas are heated. A traditional sauna uses a sauna stove which heats special stones. Water is then ladled onto the stones creating steam, which in turn heats up the sauna cabin. A far infrared sauna uses infrared heating technology to heat the body directly. Since there is no water involved, no plumbing is required, meaning the infrared sauna cabin can be placed in any room of your house.
