    Sunlighten Infrared Saunas

    Are you on the hunt for the perfect infrared sauna? Between the many brands, technology, and options, it can be overwhelming to decide which will work best for your lifestyle and needs. 

    One company you might come across in your research is Sunlighten Saunas. Founded in 1999 originally as Sunlight Saunas, this manufacturer is based out of Kansas. They offer several lines of infrared saunas that feature their own proprietary carbon heaters. 

    Below, we’re taking a closer look at Sunlighten’s quality and innovations to help you narrow down your list.

    Sunlighten Infrared Sauna Quality & Innovation

    Sunlighten infrared saunas are available in three series, each of which offers different features and technology. Regardless of the sauna style or model, the manufacturer values innovation, quality, and safety.

    Sunlighten mPulse Sauna


    Sunlighten Saunas are manufactured in Vietnam, where their team is closely involved in all stages of the production process, including:

    1. Premium Wood Selection: Sunlighten hand-selects their eco-friendly wood, kiln-dries it, and then matches the color and grains on each sauna to ensure a beautiful finished product.
    2. Quality Framework: Sunlighten saunas are twice the weight of their competitors’ because they use 100% solid, non-toxic wood. The tongue-and-groove boards are 10mm sanded to 8mm, instead of the industry standard of 8mm sanded to 5mm.
    3. Cut, Assembly & Frame Testing: The manufacturer cuts their panels precisely using a CNC machine. Each sauna is then assembled and checked for quality craftsmanship.
    4. Electrical Installation & Testing: At this stage, the factory installs all ETL-certified wiring and electronics. The sauna exterior is then sealed with a natural finish.
    5. Final Quality Check: Sunlighten assembles the sauna one more time to test electrical components and EMF levels. The sauna is then disassembled and each part is wrapped and carefully packed in two to three boxes and shipped to the Sunlighten warehouse in Kansas City. 
    6. Careful Delivery: Sunlighten usually delivers saunas curbside using a lift gate and two men who leave the package in a garage or dry place.

    The Sunlighten team works directly with their designers, engineers, and scientists to constantly innovate and improve upon their saunas. 

    Additionally, Sunlighten infrared saunas must undergo rigorous health and safety inspections, including third-party tests and certifications. They even assign home office employees to oversee the complete manufacturing process, including sourcing safe and sustainable materials to making regular visits to their Vietnam manufacturing facilities.

    When it comes to sauna safety, electromagnetic fields (EMF) are likely one of the first things that come to mind. Sunlighten saunas feature ultra-low EMF technology, meaning they give off virtually no EMF. The manufacturer explains that their exclusive manufacturing process essentially cancels out EMF levels.


    All Sunlighten Saunas are built with non-toxic premium wood, inside and out. This includes Basswood and Cedar options for both the Signature and Amplify series. The brand’s latest and greatest line of infrared saunas, the mPulse series, gives the option of Basswood, Eucalyptus, and a Euca/Cedar combo. There is no hidden plywood.

    Not to mention, the patented Solocarbon® heaters include a proprietary blend of FDA-approved materials and are heat-sealed to withstand extreme temperatures so that no unhealthy gases are released during usage. 

    Solocarbon Far-infrared Heating Panels

    Sunlighten’s original patented carbon emitters, the Solocarbon far-infrared heating panels, are used in their Signature® Far Infrared and Amplify collections. The active ingredient in these emitters is a special coating that emits the highest quality and quantity of infrared heat. Each Solocarbon panel is made up of three separate layers which are cured at 320 degrees.

    According to third-party testing, the Solocarbon heaters have a 95% emissivity. In other words, they are more efficient and consume less energy than their competitors. The large surface area of each panel evenly distributes heat so that they maintain a constant lower temperature optimal for far infrared therapy. They are also safe and effective because Sunlighten uses only FDA approved materials.

    Solocarbon 3-in-1® Heating Panel

    Sunlighten mPulse Infrared Sauna

    The manufacturer’s latest heating technology is used in Sunlighten’s mPulse infrared saunas. The Solocarbon 3-in-1 is one heater that produces mid, near, and far-infrared wavelengths at once. 

    This innovative sauna heater is designed with non-toxic, highly emissive carbonized bamboo as a protective cover on the Solocarbon heating technology. There is a separate layer of Kapton® polyimide, a lightweight material used in space applications, which can be heated independently to much higher temperatures in order to generate mid-infrared heat.

    Finally, the Solocarbon 3-in-1 emitter’s LED technology produces consistent near-infrared wavelengths without dangerous levels of heat or light.


    To further maximize the efficiency of their saunas, Sunlighten developed Magne-Seal, a patented magnetic locking system that eliminates unsightly clips, buckles, and screws. Magne-Seal enables both easy assembly and breakdown of the sauna. The system also creates a stronger seal between the walls to keep heat in and cold air out. It is both powerful and flexible, preventing cracks and warps because the wood can expand and contract as the sauna heats up and cools down.

    A Luxurious Alternative: Saunacore Infrared Saunas

    While a Sunlighten infrared sauna is a high-quality choice, USA Health & Wellness has conducted a significant amount of research showing that a Saunacore sauna is a better alternative. This Canadian manufacturer has innovations of their own and takes a great deal of pride in their quality and safety-first mindset.

    Saunacore Infrared Saunas

    100% Canadian Made

    That’s right, Saunacore engineers and manufactures all of their infrared saunas in Canada. All of their materials and parts are sourced from North America, meaning easy and efficient service or parts replacement in the rare necessary case.

    High-quality Materials & Craftsmanship

    Another perk of being Canadian-based? Saunacore sources Canadian Cedar from one of the finest mills in the country. This wood is kiln-dried and naturally decay-resistant, allowing for much thicker cabinet walls. In fact, each wall is dual or triple construction to ensure highly-efficient insulation. This is why any Saunacore infrared sauna can be converted for outdoor use!

    Plus, the company sources its metal components from one of the largest and most reputable metal suppliers in the United States. And to give you added peace-of-mind, Saunacore is the only manufacturer that uses NO adhesives or glues.

    Saunacore’s company president is even involved in the processes and products being manufactured on the plant floor daily. Every sauna is assembled and tested prior to leaving the factory, he gives his final seal of approval, and they are off!


    Each Saunacore infrared sauna is built with their patented Infra-Core concave solid ceramic heaters. These emitters housed in a surgical stainless steel housing with stainless steel deflectors and shields. 

    What does this mean? They are highly efficient and safe. But there is a lot more to this unique heating system than that—learn more about the Infra-Core technology.

    The Canadian brand doesn’t skimp when it comes to options, either. Their product catalog includes infrared saunas, traditional saunas, and dual-purpose saunas. Dual-purpose units give users the option to enjoy the benefits of both infrared and traditional heat, depending on their health needs and preferences.

    Safety First

    The Infra-Core ceramic heaters produce low EMF levels, so you can be sure you and any loved ones who enjoy a sweat can do so safely. The third-party test results found almost nonexistent EMFs!

    Finally, Saunacore ensures all of their products (excluding Sunset Infrared Saunas) are Canadian Standards Certified (CSA). This safety standards testing has rigorous requirements. The electrical components of the saunas are also tested according to UL and CE safety standards.

    If you’ve been researching Sunlighten Saunas, consider Saunacore first. To learn more about these innovative infrared saunas and for help finding the perfect unit for your home and needs, contact us at 207-619-4291 or shop our selection of Saunacore saunas today!

    Awesome hot tub, great sound and bass!

    We ordered for our personal use in 2020, October I believe it was and just received it April 2021 due to the covid b/s. Tyler was excellent with communication and keeping us updated the entire time. Will buy from again when the need arises for our vrbo rentals. This company actually has customer service a rare find these days!

    Unequaled Performance

    I am pleased to provide an objective review of USA Health & Wellness, and of the Therasauna TS5753, a full spectrum infrared sauna I ordered from them on December 9, 2020 and received on January 14, 2021.

    Why USA Health & Wellness?

    I have been using saunas, etc. for six decades, first in Europe where I spent my teenage years, and then in the United States. I have owned a custom-built Finnish/traditional sauna, a steam bath, a hot tube, and now a full spectrum infrared sauna, and I have used all except infrared saunas in gyms, hotels, etc. Hence I did not approach my most recent purchase as a complete neophyte. Even so, I found the current market place to be rich in inflated claims, with each merchant touting his products as the best, often with unsupported claims. On the USA Health & Wellness site, Garen accurately describes the journey of trying to separate fact from fiction. It was clear that he had carefully navigated the maze I was attempting to navigate, and I determined to pursue that journey in earnest with USA Health & Wellness.

    My first call was made at the end of a weekend, in the evening, in early December. To my amazement, Tyler answered the phone and explored the options with me at length. I found it remarkable that he and Garen were always available and never rushed – in the evenings, on weekends, and even on Christmas and New Year's Day when I intended only to leave messages. I posed unusual, sometimes provoking questions, to which they always replied in a forthright, informative, and affirming manner. I'm embarrassed to say that more than 100 emails have been exchanged, with them always welcoming my inquiries and occasional apprehensions. I was treated like their most important customer, as if we had been friends in college. In contrast, questions sent by email to the manufacturer, especially those with technical content, typically have been ignored or treated dismissively. On those occasions when I have been able to reach someone in customer service by phone, the individuals have been consistently welcoming and eager to help. Hence, I do not recommend email communication with the manufacturer.

    During the selection and purchase process, I read everything I could find on saunas, investigating product, health, and benefit claims (including many unfounded claims by other vendors), reaching the conclusion that USA Health & Wellness had told it straight, right from the beginning. If they are guilty of anything, they are guilty of understatement (e.g. “I estimate 1 - 2 weeks (for delivery);” it arrived only three days later, and without any damage or blemishes.)

    Having never used an infrared sauna and not wanting to use a publicly available sauna during the COVID-19 pandemic, I was left to the literature and to Tyler's guidance. As an extensive user of traditional saunas, my initial leanings were toward a Finnish sauna. Selecting an infrared sauna from Therasauna has proved to be a better choice. It heats up more quickly, the interior heat distribution can be customized, and it draws substantially fewer watts.

    My already high confidence in USA Health & Wellness developed to a point where I was comfortable paying for the sauna by personal check (without the protection of a credit card). Tyler graciously reduced the purchase price to reflect the savings of the entire credit card fee. Tyler found other creative ways to reduce my costs without detracting in any way from the product or its quality.

    Why an Infrared Sauna from Therasauna?

    USA Health & Wellness offers a variety of saunas. As best I can tell, their assessment of the strengths and weaknesses of each product is accurate. Wanting a quality product with abundant room for one person and comfortable, symmetrical space for two, I selected the Theresauna TS5753. It is part of the only line of infrared saunas made entirely in the USA; along the way I have developed a healthy aversion for anything made even in part in China. Further, Therasauna has a reputation for taking exceptional pride in their workmanship. This visible surfaces are all nicely finished (the invisible, outside back wall less so).

    Recently I began working with a world-class sports medicine physician in Park City, where many Olympic athletes reside and train. During my early January visit with him, I asked him about the possible relevance of a sauna to my regular exercise regimen. He immediately endorsed the idea and proceeded to tell me about the categories (and sub-categories, and sub-sub-categories) of saunas, and the advantages and disadvantages of each, concluding with his endorsement of full spectrum infrared saunas, characterizing them as the saunas of the future, all while I listened politely. His endorsement further solidified my confidence in my choice and in the guidance Tyler had provided right from the start.

    How has My Sauna Performed?

    One week after my sauna was assembled and usable, I spent a morning ...

    American Spa Purchase

    Great spa for a great price. No sales tax or delivery fees so that made it worth it right there. Some one is in the spa daily now it is cold outside. I would recommend the spa and buying it from USA Health and Wellness. The biggest catch is they will only drop it off at the drive way. You will need to get it to the final spot.

    Absolutely love it. It could not be more perfect!

    My thoughts on the tsp3737

    The sauna was easy to assemble, the delivery time was not as told even though it showed in stock! The delivery service was awesome, no problems with damage or unloading. We like our sauna but it has a couple of design issues, the heaters under the seat are not doing much, I think because they aren't close enough to your legs and the other quip is that I can't adjust the control up or down to add more time until it shuts off after initial setting. Outside room temp is 68 degrees and it takes about 15 minutes to reach 120 but quickly goes to 140 from there, this is an uninsulated sauna so this is acceptable. The main con is the under bench backwall heaters are too far away to feel! Also if you are looking for the Made in USA seal on the front of the bench, it was missing, so that is a concern with me! This is our first sauna and we do enjoy it almost every nite, wish we had room for a bigger unit!
