Choose a full spectrum sauna if you want near, mid and far infrared in one cabin; choose far infrared if you want far infrared heat alone. The right fit depends on wavelength coverage, available power and where you'll place the sauna.

Far infrared is one part of the infrared range. Full spectrum models add near and mid infrared, though the cabin's panels, temperatures and electrical needs still vary by model.

This guide compares those choices and a few examples, including an option for localized far infrared heat. For the basics of how panels warm a session, see how an infrared sauna works.

Full spectrum sauna vs far infrared: what is the difference?

Full spectrum covers near, mid and far infrared; a far infrared sauna focuses on far infrared. The phrase describes wavelength coverage, not a guarantee that one sauna heats faster or feels better.

A far infrared setup may suit you if that is the only range you want. Full spectrum may suit you if you prefer a cabin designed to include additional infrared ranges.

The terms can be confusing because full spectrum saunas also include far infrared. If you're comparing near and far specifically, our guide to near vs far infrared saunas explains that narrower comparison.

What does a full spectrum sauna include?

A full spectrum sauna is designed to deliver near, mid and far infrared. The implementation depends on the model: some combine light panels for near and mid ranges with separate far infrared heating panels.

For panel material trade-offs, compare ceramic and carbon infrared heaters.

For example, the SALUSHEAT combines 7 far infrared heating panels with LEDs described as 660 nm red light and 850 nm near-infrared. Its product description also states that the system combines near, mid and far infrared.

Full spectrum doesn't mean every model uses the same panel layout. Check the stated ranges and what hardware produces them before you choose.

What does far infrared mean in a sauna?

A far infrared sauna centers its heat system on far infrared. Its cabin still needs to fit your room and power supply, and its operating temperature depends on the particular model.

Don't assume that a far infrared cabin is automatically smaller, simpler or more efficient than a full spectrum one. Compare the physical dimensions and installation requirements for the exact models you're considering.

Does full spectrum feel hotter than far infrared?

Wavelength coverage alone doesn't tell you which sauna will feel hotter. Compare the temperature range, heater arrangement and conditions where you'll use the cabin.

The Dynamic Saunas Cordoba states an operating temperature up to 140°F, with a recommended comfort range of 120°F to 130°F. The SALUSHEAT states a maximum of 149°F, with lower temperatures possible in cold ambient conditions.

Those figures describe different models, not a controlled comparison between full spectrum and far infrared technology. A sauna's maximum temperature doesn't guarantee that you'll prefer its session.

If you want to compare infrared heat with a different sauna style, read our guide to infrared sauna vs traditional sauna. The heat source and typical operating approach differ, so the number on a temperature display doesn't tell the whole story.

Which infrared sauna fits your room and power?

Choose by the cabin's placement and electrical needs before choosing by wavelength. A sauna that offers the ranges you want still needs a suitable space and connection.

The Dynamic Saunas Cordoba is described as an indoor, two-person cabin using a standard 120 V, 15 A plug. SALUSHEAT's full spectrum model is described for indoor or outdoor use and requires a 120 V / 20 A connection.

The LTCCDSS is an outdoor model with a sloped roof, but its electrical requirement isn't stated here. Confirm that detail and the intended installation conditions before making a decision.

Measure ceiling height, wall clearance and the route from delivery point to the installation spot. For a cabin intended to sit outside, use our guide to choosing an outdoor far infrared sauna to think through placement and weather exposure.

What should a one-person buyer consider?

A one-person cabin is a space choice, not a separate infrared category. Look for a model whose interior and exterior dimensions suit your room, then decide whether you want far infrared or full spectrum coverage.

The models compared here are larger: Cordoba is designed for two adults, and the two outdoor cabins are described for multiple people. If you're shopping for a single seat, our guide to a one-person full spectrum infrared sauna focuses on that size and setup question.

Is an outdoor full spectrum sauna practical?

An outdoor full spectrum sauna can work when its design, location and power connection match your climate and site. Check the stated operating range and protect the unit as its instructions require.

The LTCCDSS describes a stated outdoor temperature range of -5°F to 120°F and a sloped roof intended to improve drainage. The SALUSHEAT describes outdoor use, but its temperature guidance notes that colder ambient conditions affect the temperature it reaches.

These product details don't replace site preparation or installation instructions. Confirm the foundation, weather exposure, clearances and circuit before settling on an outdoor location.

What do the example products offer?

The three cabins here provide full spectrum coverage, while the HealthyLine mat offers far infrared heat without a sauna cabin. They serve different room and session needs, so compare the use case as well as the heat type.

How should you compare full spectrum and far infrared models?

Compare the details that affect your use: wavelength coverage, heater layout, size, power and placement. A short checklist helps separate a useful feature from a label.

Start with the heat ranges. Full spectrum models are designed to include near, mid and far infrared; a far infrared model focuses on far infrared.

Next, review the cabin's stated dimensions and capacity. A two-person design may be unnecessary in a small room, while a compact model may not fit your preferred seating position.

Check the electrical requirement against the outlet and circuit where the sauna will go. The 15 A Cordoba and 20 A SALUSHEAT illustrate why the word “infrared” isn't enough to plan installation.

Finally, confirm whether the cabin is intended for indoor or outdoor use. Weather exposure, temperature limits and site preparation can change which model makes sense.

What should you ask about the heater setup?

Ask which ranges the sauna delivers and how its panels are arranged. A brand may describe a full spectrum system while using more than one type of panel.

Look for explicit details about near, mid and far infrared rather than relying on the product name alone. Also check whether the stated temperature is a maximum or a recommended comfort range.

If the details leave a practical question unanswered, ask the manufacturer before ordering. Don't assume the same panel arrangement or electrical setup across models with similar names.

Which should you choose?

Choose full spectrum if you want near, mid and far infrared coverage; choose far infrared if far infrared alone matches your preference. Then confirm the cabin's fit, power and installation location.

For a full spectrum cabin, the Cordoba offers an indoor two-person format with a 120 V / 15 A plug. The SALUSHEAT is a larger indoor or outdoor option with a 20 A requirement.

For an outdoor installation, the LTCCDSS has an outdoor design and stated temperature range, but you'll need to confirm electrical details. For localized heat without a cabin, the HealthyLine mat is the far infrared option here.

Frequently asked questions

Is full spectrum better than far infrared?

Full spectrum covers near, mid and far infrared, while far infrared focuses on the far range. Neither is automatically better for every buyer.

Choose based on the wavelength coverage you want, available room and power, and whether you prefer a cabin or a smaller heat device.

Does full spectrum mean more heat?

Full spectrum describes wavelength coverage, not a guaranteed higher temperature or stronger session. Compare each sauna's stated temperature range, heater layout and room conditions.

A model with more wavelength ranges may offer more types of infrared, but that alone doesn't tell you how warm or comfortable it will feel.

Can you get near, mid and far infrared in one sauna?

Yes. Full spectrum saunas are designed to include near, mid and far infrared.

Check how the specific model delivers each range, since one design may use separate light panels and far infrared heaters while another may use a different setup.

Is a far infrared mat the same as a far infrared sauna?

No. A far infrared mat provides localized heat across its surface, while a sauna is a cabin intended for a whole-body session.

A mat can suit a smaller space or focused use, but it doesn't replace a sauna enclosure.

What should you check before installing an infrared sauna?

Measure the cabin and delivery route, then confirm indoor or outdoor placement, circuit requirements and the maker's temperature guidance. For example, the SALUSHEAT requires 120 V / 20 A, while the Cordoba states 120 V / 15 A.

Have an electrician review a circuit if you're unsure.
