The customer service was really great. We couldn’t decide between three models and we called and spoke to Pedram who took care of us. He really cared about making us feel good. Thanks and wish you all the best. :)

2-PERSON FULL SPECTRUM COMPARISON
Finnmark FD-2 vs Golden Designs GDI-8020-03
Compare two 2-person full spectrum infrared saunas from Finnmark and Golden Designs. Both operate on 120V power, but they use different approaches to infrared heating, near-infrared delivery, cabin construction, controls, lighting, and EMF classification.
About This Collection
Shop full spectrum infrared saunas from Finnmark and Golden Designs in compact personal and larger multi-person sizes. These indoor saunas use more than one infrared heating technology to create a broader infrared system than a sauna built only around standard far-infrared carbon panels.
Full-spectrum systems are not all built the same. Finnmark and Golden Designs use different combinations of infrared heaters and emitters, so it is worth comparing how each sauna produces its infrared output rather than choosing by the “full spectrum” label alone.
Full Spectrum Infrared Saunas for Home Use
A full spectrum infrared sauna is designed to use multiple parts of the infrared spectrum rather than relying on a single heater type. The exact way this is achieved depends on the manufacturer, which is why two saunas described as full spectrum can use noticeably different heating systems.
Finnmark combines its Spectrum Plus™ infrared heaters with Spectrum Carbon™ panels and near-infrared LED technology in its dedicated full-spectrum models. Golden Designs takes a different approach in its current Reserve Edition models, combining near-infrared heating elements with far-infrared carbon panels.
Why Full Spectrum Sauna Designs Differ
“Full spectrum” describes the infrared approach, not one universal heater configuration. Heater placement, emitter type, cabin construction, electrical requirements, controls, and infrared delivery can vary from one model to another.
This makes the individual sauna design more important than the category name by itself. A buyer comparing Finnmark with Golden Designs should look at how the complete heating system is built and how well the cabin fits the intended space and number of users.
How to Choose the Best Full Spectrum Infrared Sauna
Start with how the sauna will be used. A smaller cabin can make sense for one person or a more compact home setup, while a larger sauna provides more seating space for shared use. From there, compare the heating approach used by each manufacturer and decide which design best matches what you want from a full spectrum infrared sauna.
Installation should also be considered before choosing a model. Full spectrum infrared saunas can have different power requirements even when their seating capacities are similar, so confirm that your planned location can support the sauna you are considering.
Our comparison section provides the model-level specifications needed to review these differences side by side before choosing a sauna.

Full Spectrum Infrared Sauna FAQs
Which is better: far infrared or full spectrum sauna?
Neither is automatically better. A far infrared sauna focuses on far-infrared heating, while a full spectrum sauna uses more than one infrared range or heating technology. The better choice depends on the type of heating system you want, the cabin design, electrical requirements, and the specific sauna you are comparing.
Buyers who prefer a simpler far-infrared system can compare our far infrared saunas. If you want multiple infrared technologies in one cabin, a full spectrum model may be the more relevant category.
Is a full spectrum infrared sauna worth it?
It can be worth considering if you specifically want a sauna that combines multiple infrared technologies rather than relying only on far-infrared carbon panels. The added value depends on how the manufacturer builds the heating system and whether the other specifications fit your needs.
Do not choose a sauna only because “full spectrum” appears in the product name. Compare the actual heater design, cabin size, electrical requirements, controls, construction, and manufacturer documentation before deciding whether the additional technology is worthwhile for you.
Does full spectrum mean there are separate near, mid, and far infrared heaters?
Not necessarily. The term “full spectrum” does not tell you the exact hardware arrangement inside the sauna. Manufacturers can use different combinations of heaters, carbon panels, infrared elements, and LED technology to create their full spectrum systems.
This is why the manufacturer specifications matter more than simply counting the words “near, mid, and far.” Look for documentation that explains what each heater or emitter actually produces and where it is positioned in the cabin.
Is red light therapy the same as near infrared in a sauna?
No. Visible red light and near infrared are different parts of the light spectrum. A sauna can include a visible red-light feature while using a separate near-infrared heater or emitter as part of its infrared system.
When comparing saunas, do not assume that a red interior light is the near-infrared component of the heating system. Check the manufacturer specifications to see whether near infrared is produced by dedicated heating elements, LEDs, or another documented emitter.
Is full spectrum the same as Low EMF or Near Zero EMF?
No. “Full spectrum” describes the infrared heating approach, while Low EMF and Near Zero EMF describe electromagnetic-field measurements or manufacturer classifications. They are separate product characteristics.
A full spectrum sauna can contain heaters with different EMF specifications, so an EMF claim should always be tied to the exact heater, measurement distance, unit, and test conditions. If EMF classification is a priority, compare our low EMF infrared saunas.
Does a sauna with more infrared heaters automatically perform better?
No. Heater count by itself is not enough to judge an infrared sauna. Individual heaters can differ in wattage, infrared range, construction, size, placement, and purpose.
A more useful comparison looks at the complete heating system: total published power, heater or emitter type, placement around the cabin, cabin volume, electrical requirements, and how the manufacturer documents the infrared technologies being used.
Is a full spectrum infrared sauna safe?
The “full spectrum” label by itself does not determine whether one sauna is safer than another. Safe use depends on choosing an appropriately certified product, following the electrical and installation requirements for the exact model, and operating it according to the manufacturer's temperature, time, and safety instructions.
Manufacturer manuals also include precautions for people who are pregnant, taking medications, or living with certain medical conditions. In those situations, review the model's safety instructions and speak with a qualified healthcare professional before sauna use.

What Customers Are Saying
As an older adult starting to use my Power Plate Move I first enjoy the increased circulation of my lower extremities! Then comes balance work, stretching and toning! I love the machine so much I bought two!
This device helps to keep me comfortable. I am also using it after my recent surgery to help with healing. I will continue to use it daily since I see the benefits first hand and I love it.
I use my power plate at least once a day. Feel so relaxed after using it and my muscles are getting very toned especially in my arms and legs. Had an imitation vibration plate before and there’s no comparison. Power Plate blows it out of the water. Such a difference and definitely worth the extra money.
Smooth delivery process. We spoke to other companies and the response was vague. What I liked most about our conversation was that Pedram asked me what was my intention and why I wanted to buy a sauna instead of pushing a sale. This was very different. Appreciate the honesty.
I got an email from Pedram and he mentioned how we could add a sauna to our business. At first, I wasn’t much for it but when we set up an audit and reviewed my business, I liked what I saw. It was definitely an investment on our part but the service has been great for our clients. Thanks again for your support and caring.
I needed something for my basement but didn’t know what to buy. I saw this brand before but couldn’t make a decision. I called Pedram and he walked me through it and we even looked at my floor plans for my basement. This was really fun and I am enjoying it. You guys rock!
My body is not the same as it used to be, but I wanted something that would be ok for me and also give me a good workout. I liked how I was recommended to go with STEPR because it is a low impact fitness machine. Looks good in my garage and my son uses it too.
I was honestly on the fence for weeks because it is not a small purchase. I kept looking at different brands and reading reviews. What made the difference was actually getting on the phone and talking through my space and what I wanted out of it. It feels solid, heats up fast, and has become part of my nightly routine. No regrets at all.
I bought this mostly for recovery after workouts but ended up using it way more than I expected. I sit on it while reading and sometimes just lay on it before bed. It is calming in a way I did not expect. Shipping was smooth and everything came well packaged. Very happy with it so far.
I was not sure if I really needed a massage chair or if it was just one of those things that sounds nice but never gets used. I can honestly say this gets used almost every day. I work long hours and my lower back is usually tight by the end of the day. I sit in it for about twenty minutes in the evening and it actually helps me unwind.
