Buying the best infrared sauna is not always easy. Many brands make bold promises. On the other hand, many products appear similar but differ significantly in terms of safety, materials, heater quality, durability, and actual performance.

A low-quality sauna can waste energy, heat unevenly, off-gas chemicals, or even deliver unsafe EMF levels. Read on to understand how infrared therapy works, how to choose the right infrared sauna for your needs, the features that matter most, and how to evaluate build quality, heater technology, size options, and warranty terms.

What Is an Infrared Sauna and How is Infrared Heat Different?

The best infrared saunas use safe infrared light to heat your body directly. The heat penetrates the skin and warms your muscles, tissues, and joints from the inside out. This differs from traditional saunas, which heat the air to very high temperatures. Infrared saunas operate at a comfortable 110–140°F. Yet the heat feels deeper because infrared wavelengths reach several millimeters into the skin. This supports internal heating and increased circulation, rather than creating a hot external environment. Infrared saunas use three distinct wavelengths, each of which interact with the body differently, as seen below:  

·       Near-Infrared (NIR)

These short wavelengths primarily target the skin surface. NIR is popular for people who seek anti-aging benefits or light therapy alongside heat.

·       Mid-Infrared (MIR)

Medium-length wavelengths that penetrate deeper than near infrared. They can help reduce inflammation and support faster recovery after workouts.

Far-Infrared (FIR)

These are the deepest-penetrating wavelengths, and most home infrared saunas focus on FIR, providing the most comprehensive therapeutic experience.

Which Type of Infrared Sauna Should You Buy for Your Home?

Choosing the right outdoor infrared sauna is crucial. The type determines heat quality, health benefits, and overall performance. So, should you choose far-infrared, near-infrared, or a full-spectrum sauna? Here are the pros and cons.

Quality wood and build ensure durability, safety, and a clean, comfortable sauna environment. Ensure the sauna uses solid natural wood. Avoid plywood or particle board. Low-quality materials may warp, crack, or release volatile organic compounds (VOCs) under heat. Good wood types resist heat stress, last longer, and often impart a pleasant aroma. Ensure construction uses non-toxic adhesives and finishes, especially if you’re sensitive to smells or chemicals. Here are wood options to consider. 

·       Canadian Hemlock

Canadian Hemlock is used by many premium sauna brands. It is suitable because it is:

  • Non-toxic and chemical-free
  • Strong and warp-resistant, even under repeated heat cycles
  • Has a light color that looks modern and clean in homes
  • Excellent value for durability and longevity

Canadian Red Cedar

Canadian Red Cedar is a durable, aromatic softwood prized for its natural resistance to decay, warm reddish tones, and stability, making it an ideal choice for saunas. This wood:

  • Is naturally antimicrobial, resisting mold and mildew
  • Has an aromatic scent that enhances relaxation
  • Is extremely durable and moisture-resistant
  • Features a beautiful reddish color and premium aesthetic

Basswood

Basswood is a light, hypoallergenic hardwood known for its smooth texture, low resin content, and stability. It’s commonly used in saunas due to its clean, gentle nature. Basswood is:

  • Hypoallergenic for people with allergies or sensitivities
  • Very smooth texture and pleasant finish
  • No strong smell
  • Despite the advantages, basswood is
  • Softer wood that can dent more easily
  • Less durable over long-term use

Spruce

Spruce is a strong, lightweight softwood valued for its bright color, clean grain, and good acoustic qualities. It’s commonly used in saunas due to its durability and stability. However, spruce is prone to cracking under heat and is not visually appealing. Other pros include:

  • Lower-cost option for budget buyers
  • Lightweight and easy to assemble

Which Sauna Heater Type Offers the Best Experience?

The best outdoor infrared sauna heater depends on the experience you want. Traditional electric or wood-burning heaters offer the classic high-heat, steamy environment many people prefer. Infrared heaters provide gentler, deeper warmth at lower temperatures, ideal for comfort and longer sessions. Hybrid heaters combine both for maximum flexibility. Overall, traditional heaters provide the most authentic sauna experience, while infrared heaters suit those who prefer milder heat.

What Sauna Safety Features Should You Look For?

When selecting a weatherproof outdoor infrared sauna, look for safety features that protect you and enhance the comfort of each session. A built-in timer prevents overheating by automatically shutting the sauna off. Temperature limiters prevent the heater from overheating, while proper ventilation ensures steady airflow.

Cool-touch door handles, tempered glass, and sturdy construction add extra protection. Inside, ergonomic seating, non-slip flooring, and low-EMF infrared panels (available in infrared models) enhance overall safety. Look for reliable certifications from recognized testing organizations to ensure the sauna meets established safety standards.

Why Do EMF Levels Matter?

Choose saunas with low or ultra-low electromagnetic field (EMF) emissions. High EMF or poorly shielded wiring can expose you to unnecessary electromagnetic exposure. Look for real test data showing EMF readings, ideally under 3 milligauss (mG) at sitting distance. Many high-end units aim even lower. This ensures wiring and components meet safety standards. Low EMF and correct wiring reduce potential health risks and ensure safer long-term use. They matter most for users who spend 20–45 minutes per session inside the home sauna. Here is an EMF checklist to help you make an informed choice.

  • Ensure levels are independently tested and certified
  • Look for EMF output below 3 milligauss at the sitting position
  • Choose saunas with shielded wiring to minimize exposure
  • Consider brands that prioritize ultra-low EMF engineering

Are Electrical Certifications Important?

Electrical certifications are important because they confirm a sauna has been tested and meets strict safety standards. Since saunas involve high heat, powerful electrical components, and long usage times, certified equipment helps prevent electrical faults, fire risks, or wiring issues. Certifications like ETL, UL, CE and ROHS compliance, or CSA also ensure the materials, wiring, and heaters perform reliably under stress. They also protect your investment and safety for many years. When buying an infrared sauna: 

  • Opt for saunas with clear safety certifications and documentation. This ensures compliance with electrical standards and safer operation.
  • Check the warranty terms. Longer warranties indicate manufacturer confidence. Good units often offer extended heater and structural coverage
  • Inspect overall build quality. Solid joints, good sealing, quality heater panels, and clean wiring. Avoid cheap imports with hidden flaws
  •  Avoid saunas without proof of any certifications.

Ensure the Sauna is not made with Toxic Materials

A high-quality luxury home sauna should be built with materials that remain safe when heated, meaning it must not off-gas chemicals during use. The sauna you choose should:

  • Have no particleboard or plywood inside the cabin
  • Feature non-toxic, water-based adhesives
  • Be made of FSC-certified wood to ensure sustainable sourcing
  • Have low-VOC finishes that do not release fumes
  • Produce zero chemical smell during operation

What Sauna Features Should You Consider Before Buying?

Modern saunas incorporate technology and features that enhance comfort and the overall experience. While they may not significantly impact the sauna’s core function, they can enhance comfort, mood, and the overall experience. These include:

  • Chromotherapy / LED light therapy
  • Audio integration (speakers or Bluetooth)
  • Touch controls for temperature, timer, and lighting
  • Glass doors or windows for brightness and a modern look
  • Ventilation or an ionizer for better air quality 

How Much Should Your Sauna Budget be?

  • Portable Infrared Saunas $150–$6,000
  • 1-Person Saunas $900–$5,399
  • 2-Person Saunas $1,500–$10,699
  • 5 Person Saunas $6,000–$13,799
  • Luxury Full-Spectrum Models $10,000–$17,199

How Much Space Do You Need for Installation?

To determine the required space for a sauna installation, start by measuring the floor area where it will be situated, ensuring there is sufficient room for the sauna’s footprint, plus a small buffer around it. Check the ceiling height, since most saunas require a minimum clearance for proper heat circulation.

Ensure there is sufficient space for the door to open fully and provide safe access in and out. If it is an indoor sauna, confirm that there is adequate ventilation and sufficient room for electrical connections. For outdoor infrared saunas, consider level ground, weather protection, and access to power. Always compare your measurements with the manufacturer’s specifications before installation.

How Difficult Is Installation?

Considering the sauna installation process before buying ensures the model you choose fits your space, electrical setup, and lifestyle without unexpected complications. Understanding installation needs, such as floor space, ceiling height, ventilation, and power requirements, helps avoid costly modifications or delays. It also allows you to determine whether you can manage the installation yourself or if you need professional help. Planning ensures a smooth setup, safer operation, and a sauna that seamlessly integrates into your home.

What Warranty Should Your Sauna Include?

       A warranty reflects product quality. Consider the following: 

  • A lifetime warranty for heaters in premium brands
  • 5–10 years for wood cabin structures
  • 1–5 years for electronics like speakers and control panels
  • Replacement parts available long-term
  • Clear return and refund policies
  • Avoid brands offering short warranties

What Are Common Mistakes Infrared Sauna Buyers Make?
