Home infrared saunas have come a long way from a niche wellness purchase. They now show up in home gyms, basements, and spare bedrooms, and the market is full of sleek wooden cabins promising gentle heat and a spa-like experience without leaving the house.
At the same time, shopping for one can feel genuinely confusing. Listings throw around terms like FAR infrared, full spectrum, low EMF, carbon heaters, Canadian hemlock, chromotherapy, and red light therapy, and it is not always clear what those words mean or what you are actually paying for.
This infrared sauna buying guide walks through ten things worth knowing before you buy, so you can compare home infrared saunas with confidence and spend your money on what matters most to you.

1. What Is an Infrared Sauna?
Traditional saunas, like the classic Finnish-style sauna, heat the air around you. They typically run at high air temperatures, and heat reaches your body through the surrounding hot air.
Infrared saunas work differently. Instead of heating the air first, infrared heaters transfer radiant heat to your body directly. That is why infrared saunas generally operate at lower air temperatures than traditional saunas while still producing a feeling of warmth for many users.
Beyond that basic distinction, infrared saunas vary considerably from one model to the next. The type and number of heaters, the materials used in the cabin, EMF measurements, interior and exterior size, electrical requirements, warranty coverage, and available features all differ between products. This guide covers each of those areas in turn.
2. FAR Infrared vs. Full-Spectrum Infrared
FAR infrared refers to the portion of the infrared range used by most home sauna heaters today, and FAR infrared saunas are the type most shoppers encounter when browsing compact, plug-in home cabins.
Some products describe themselves as full-spectrum, which usually means they are designed to emit near-, mid-, and far-infrared wavelengths rather than far-infrared alone.
Here is the important part: a full-spectrum label does not automatically make a sauna better, and it does not automatically justify a higher price. Instead of shopping by label, compare the complete product. Look at the heater types and count, the cabin materials, the documented EMF measurements, the size, the electrical requirements, the warranty, and the price, and judge the sauna as a whole.
3. What Does "Low EMF" Really Mean?
Many listings use phrases like low EMF or ultra-low EMF as a selling point, but those phrases are marketing terms, not standardized measurements. Shoppers should look beyond the label.
Instead, check the actual EMF measurement a manufacturer reports, and pay attention to the details that shape what that number really means:
- Where the measurement was taken, such as at the heater surface or at a seated position
- What distance from the heaters the reading was taken at, since EMF readings change with distance
- Whether the testing was independent or conducted by the manufacturer
It is also worth knowing that measurements taken at different distances cannot necessarily be compared directly. A reading reported at one distance is not automatically better or worse than a reading reported at another; the measurement conditions have to match before the numbers mean the same thing.
BodyWell1 does not establish a "safe" EMF threshold for home saunas. We encourage shoppers to gather the specific numbers available for each model they are considering and decide what is comfortable for them.
4. Sauna Materials Matter
The wood that makes up your sauna cabin is a bigger part of the purchase than it might first appear. Canadian hemlock and cedar are two of the most common woods in home infrared saunas. Hemlock is a light-colored wood often chosen for compact cabins, while cedar has a distinctive aroma and its own look and feel. Other woods appear as well, and each brand describes its choice differently.
If cleaner living is part of what draws you to a sauna at home, it is worth digging past the wood species. Consider checking the manufacturer's documentation or asking directly about:
- Adhesives and composite materials used in the panels
- Finishes, stains, and sealants applied to the wood
- Any VOC (volatile organic compound) information the maker publishes
- Off-gassing claims and how they were evaluated
Specific material information is far more useful than vague "non-toxic" marketing. If a brand cannot tell you what is in the panels, the adhesive, or the finish, that is useful information too.
5. 1-Person vs. 2-Person Infrared Saunas
Advertised capacity can be misleading. A "2-person" sauna may fit two smaller users comfortably or one person with room to spare, and the difference comes down to interior dimensions rather than the marketing copy.
Before you buy, check the interior dimensions, not just the exterior footprint. Then measure what you actually have at home:
- The floor space the sauna will occupy
- Ceiling clearance, including any light fixtures, fans, or beams overhead
- Door clearance for moving the sauna into the room
- Assembly access, since many cabins assemble in place and need room to open the panels
A 1-person infrared sauna can be the right call when space is tight, while a 2-person infrared sauna works best when you have measured carefully and know the footprint fits.
6. Check Electrical Requirements Before Buying
Electrical requirements are one of the most commonly overlooked details in a home sauna purchase. Some compact infrared saunas operate on standard 120V household service, while larger models may require different electrical service.
Before you order, verify the model's voltage, amperage, and any dedicated circuit requirements, and read the installation instructions before the unit arrives. If the sauna needs a dedicated circuit or other electrical work, that is a conversation to have with a qualified electrician. It is much easier to budget for that work before the sauna arrives than after it is sitting in a crate in your living room.
7. Infrared Heat vs. Red Light Therapy
This is where shoppers most often run into confusing claims, so it deserves its own section. Infrared sauna heat, chromotherapy lighting, red-colored lighting, and dedicated red or near-infrared photobiomodulation devices are not automatically the same thing.
Some saunas include chromotherapy lighting systems, which may include a red-light feature. That does not, by itself, make the sauna a therapeutic red-light device.
If a sauna advertises red light therapy, check the actual details: the wavelengths the product emits, the irradiance reported, and the manufacturer's specifications for the lighting system. Do not assume that any red-colored light provides the wavelengths or intensity that dedicated red-light products are designed to deliver.
8. What Does the Research Say About Sauna Bathing?
Sauna bathing has attracted a substantial body of research, and it is fair to say the topic is genuinely interesting. It is equally important to understand what that research does and does not show.
A review of the sauna research
A review by Laukkanen, Laukkanen, and Kunutsor published in Mayo Clinic Proceedings in 2018 examined the cardiovascular and other potential benefits of sauna bathing. The authors describe research that has identified potentially beneficial associations between regular sauna bathing and cardiovascular and other health outcomes.
One caveat matters: much of the strongest long-term evidence comes from studies of traditional Finnish sauna bathing, which is a different practice from using a residential infrared cabin.
The dementia study
A separate observational study by Laukkanen and colleagues, published in Age and Ageing in 2017, followed middle-aged Finnish men over long-term follow-up and found an association between more frequent sauna bathing and lower rates of dementia and Alzheimer's disease.
It is important to be precise about what that means. An observational association does not prove that sauna bathing prevents dementia or Alzheimer's disease. Studies like this identify patterns worth studying further; they do not establish cause and effect.
What this means for a home infrared sauna
These studies are interesting and worth reading, but they should not be read as proof that a particular home infrared sauna delivers the same benefits. Infrared saunas differ from traditional Finnish saunas in temperature, heater design, and how the body is heated, and the research on residential infrared cabins specifically is narrower.

9. How Much Should You Spend?
There is no single right price for a home infrared sauna, and the most expensive sauna is not automatically the best one for your situation. Rather than anchoring on price alone, compare the full picture:
- Construction and materials
- Heater type and count
- Interior and exterior dimensions
- Documented EMF testing and how it was performed
- Electrical requirements
- Warranty coverage
- Customer support and reputation
- Safety certifications the manufacturer claims
- Availability of replacement parts
- Price relative to all of the above
A More Accessible Example: Dynamic Barcelona FAR Infrared Sauna
To see how this works in practice, it helps to walk through one specific product. The Dynamic Barcelona 1–2 Person Low-EMF FAR Infrared Sauna is an example of a compact home infrared sauna, not "the best sauna" for everyone.
It is built with Canadian hemlock, uses FAR infrared carbon heating panels, and operates on 120V household service. Its compact size is the reason it fits spaces a larger cabin would not, and that is exactly the trade-off shoppers make when they choose a smaller model. Whether it suits you depends on your space, your electrical setup, and how you weigh the factors in the checklist above.

- What wood and materials are used in the cabin?
- What adhesives and finishes are used?
- Is VOC information available?
- What are the interior and exterior dimensions?
- What are the electrical requirements?
- Does the sauna require a dedicated circuit?
- What safety certifications does the manufacturer claim?
- What does the warranty cover, and for how long?
- Are replacement parts available?
- If red light therapy is advertised, what wavelengths and irradiance are documented?
Final Thoughts
A home infrared sauna can be an appealing wellness purchase, and for many households it is a good one. The key is to look beyond health promises and marketing buzzwords and to compare the things you can actually verify: the technology, the materials, the electrical requirements, the warranty, the manufacturer's support, and the documented testing.
Sauna research is interesting and growing, but much of the strongest long-term evidence involves traditional Finnish sauna bathing rather than residential infrared cabins. That is not a reason to avoid infrared; it is a reason to be a careful shopper and to choose a home sauna for its build quality, fit, and value rather than for claims about outcomes.
If you are considering a compact option to start with, the Dynamic Barcelona 1–2 Person Low-EMF FAR Infrared Sauna is a natural place to start comparing.
