Benefits of Infrared 

  • The technology of the Spectrum Plus incoloy heaters warms your core body temperature, producing a cleaner, healthier sweat while lowering blood pressure, and maintaining heart health.
  • The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate much like a traditional sauna without the unbearable heat temperatures. This deeper penetration through sweating goes beyond the muscle and fat rather than a traditional or hot air sauna.  As a result, you're able to work up the best possible sweat in the least amount of time.
  • Spectrum Plus heaters remove 17% more toxins such as cholesterol, fat-soluble toxins, toxic heavy metals, sulfuric acid, sodium, ammonia, and uric acid.
  • Full Spectrum Sauna combination of long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus™ infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and a better experience than any other sauna.
  • Reap the benefits of a more natural pain relief remedy with every infrared sauna session.
  • Athletes can appreciate a faster muscle recovery with increased blood flow to the muscles, delivering more concentrated oxygen and creating more energy to heal.

      Owner's Manual

      Finnmark Design's infrared Saunas Are Made with Your Health in Mind— with Upgraded Heaters for Therapeutic Heat (up to 170°!), the Highest-Quality Cedar Wood, & Ultra-Low EMF!

      Shopping for infrared saunas can be confusing. You can easily waste countless hours and still not know which sauna you should choose.

      Here are 10 reasons why Finnmark Designs manufacturers the BEST infrared saunas on the market:

      • High, Therapeutic Temperature—most companies max temperature is 145° to 150°, which is well below the temperature that ALL the clinical research studies show offers health benefits.
      • Ceramic and Carbon Heaters for Whole-Body Therapy—the only sauna with this heater combination, giving you the best heater combination for 360° heat therapy.
      • Highest-Quality Cedar Wood that Won’t Mold and Won’t Off-Gas Toxic Chemicals—most other companies make you pay more for cedar or use low quality cedar that isn’t kiln dried correctly.
      • Ultra-Low Radiation (All 4 Types: EMF, ELF, EMI, and RF)—we’re the ONLY sauna company that has both low-emitting heaters AND upgraded, shielded electrical components, for the lowest electromagnetic fields possible.
      • Full-Spectrum Infrared Rays for the Highest Healing Potential—you get near- mid- and far-infrared, without the dangerous food heat lamps that many other infrared sauna companies use.
      • Safe and Certified by 3rdParties. Our saunas are backed by more safety certifications than any other sauna company.
      • Easy to Use. Setting up your infrared sauna in your home is WAY easier than other sauna brands. Any two people can do it, with just a screwdriver.
      • Heats Up Fast. With Finnmark Designs, you get the fastest heat-up times in the industry—under an hour up to 170° on a standard outlet. (Mini and Hybrid 2.0)
      • Comfortable and Relaxing. With whole-body therapy, you’ll feel the soothing heat throughout your sauna, with no cold spots—and special attention to the back, where 80% of Americans report pain and inflammation..
      • Backed by an Excellent Warranty. In the U.S., a “lifetime” warranty is considered 7 years, so don’t be fooled! Finnmark Designs has a warranty that covers your entire sauna for 10 years. Plus, our Spectrum Plus™ heaters are backed by an unconditional lifetime warranty—because we’re THAT confident in them.

      We manufacturer our infrared saunas in an actual sauna factory, not some furniture factory that builds couches and loveseats.  A factory that has decades of experience building infrared saunas.

      What Doctors Say…

      An Investment Towards Optimal Health

      Dr. Steve Masley

      An Investment Towards Optimal Health

      “Heating your core temperature is a powerful tool to enhance your health. It protects your heart, burns calories, and helps you sweat away toxins. INFRARED heat is the most comfortable way to accomplish this.

      Plus, you’re healing your skin, relaxing your muscles, producing ‘feel good’ endorphins, and getting a PASSIVE cardio workout!

      I love using my own sauna and believe it is an excellent investment towards optimal health.”

      —Steven Masley, MD, FAHA, FACN, CNS

      Focuses on how lifestyle choices impact brain function, heart disease, and aging

      Best-selling author Ten Years Younger, The Better Brain Solution, and more.

      Favorite Health Tool

      “Infrared sauna is my FAVORITE health tool. Everyone who gets one LOVES IT. Just sweat it out.

      There is nothing more powerful for detoxifying your body and stimulating your immune system!”

      Research Behind Saunas Is Strong

      “The research behind the health potential of saunas is strong.

      Heat stress activates a protein called FOXO3, which is known as the longevity gene.

      FOXO3 affects the immune function, DNA repair, alleviating pain, and STEM CELL activation!

      This is one wellness tool that does SO much for you, all in one.”

      Why Trust Finnmark Designs?

      • Backed by Certifications. Spectrum Plus Heaters are recognized by the prestigious Underwriters Laboratories. Saunas are ETL and CE certified. Plus, the cedar comes from a mill approved by the Forest Stewardship Council, ensuring forests will be around for generations to come. We use only dead trees—we never cut down living trees.
      • Excellent Warranties. Parts are NOT interchangeable between sauna brands, so you want to choose a company you can trust. Our factory has been manufacturing saunas for decades.
      • Upgraded Supplies. The power supplies and controllers we use are higher-end than other quality saunas. We upgraded capacitors, power relays, and wiring—these new materials should last 12-15 years. (Other saunas use parts that last 5-7 years.) The internal wiring is 14 AWG, and shielded to protect you—which makes the entire sauna low radiation instead of only the heaters.
      • Knowledgeable, Highly Trained Customer Service. The average number of years of sauna experience for people in our customer service department is 5 years.

      Best Investment for Health

      “Just three sessions a week for three months and my chronic neck pain is finally gone.

      I can say without a doubt that regular infrared sauna therapy was the best investment I’ve made for my health and the health of my family.

      It moved the mark on our health the fastest and most noticeable, more than anything we’ve done prior. It has exceeded my expectations.”

      Kelly R.

      Easy to Purchase & Use

      “The sauna was easy to purchase. Easy to put together. I have loved being able to use it in the privacy of my home.

      I have enjoyed my sauna more than I ever dreamed I would. It doesn’t take up much space, so if space is an issue you can still make it work. Because it is in my home, it is convenient and easy to use, and I can use it every day.

      It requires very little time and maintenance for care and cleaning. It is a wonderful aid for good health.”

      Linda M.

      Outstanding Materials & Craftsmanship

      “I use this sauna every night and love the improvement in my sleep. Because it takes away inflammation that can occur from running, I am able to work out the next day consistently without achy joints. My skin is so healthy and radiant since I began using the sauna.

      I like the integrity of the company, and the materials and craftsmanship they have chosen are outstanding. I feel it is an environmentally friendly and health-conscious product. Service from the sales staff was very helpful in choosing which unit would suit my needs.”

      Benefits of Infrared 

      • The technology of the Spectrum Plus incoloy heaters warms your core body temperature, producing a cleaner, healthier sweat while lowering blood pressure, and maintaining heart health.
      • The natural heat produced by the Spectrum Plus heaters is designed to achieve a more controlled hot climate much like a traditional sauna without the unbearable heat temperatures. This deeper penetration through sweating goes beyond the muscle and fat rather than a traditional or hot air sauna.  As a result, you're able to work up the best possible sweat in the least amount of time.
      • Spectrum Plus heaters remove 17% more toxins such as cholesterol, fat-soluble toxins, toxic heavy metals, sulfuric acid, sodium, ammonia, and uric acid.
      • Full Spectrum Sauna combination of long-wave Spectrum Carbon 360 infrared panels with UL-listed short-wave Spectrum Plus™ infrared panels. This combination provides higher temperatures, full body coverage, deeper penetration, and a better experience than any other sauna.
      • Reap the benefits of a more natural pain relief remedy with every infrared sauna session.
      • Athletes can appreciate a faster muscle recovery with increased blood flow to the muscles, delivering more concentrated oxygen and creating more energy to heal.

          Owner's Manual

          Finnmark Design's infrared Saunas Are Made with Your Health in Mind— with Upgraded Heaters for Therapeutic Heat (up to 170°!), the Highest-Quality Cedar Wood, & Ultra-Low EMF!

          Shopping for infrared saunas can be confusing. You can easily waste countless hours and still not know which sauna you should choose.

          Here are 10 reasons why Finnmark Designs manufacturers the BEST infrared saunas on the market:

          • High, Therapeutic Temperature—most companies max temperature is 145° to 150°, which is well below the temperature that ALL the clinical research studies show offers health benefits.
          • Ceramic and Carbon Heaters for Whole-Body Therapy—the only sauna with this heater combination, giving you the best heater combination for 360° heat therapy.
          • Highest-Quality Cedar Wood that Won’t Mold and Won’t Off-Gas Toxic Chemicals—most other companies make you pay more for cedar or use low quality cedar that isn’t kiln dried correctly.
          • Ultra-Low Radiation (All 4 Types: EMF, ELF, EMI, and RF)—we’re the ONLY sauna company that has both low-emitting heaters AND upgraded, shielded electrical components, for the lowest electromagnetic fields possible.
          • Full-Spectrum Infrared Rays for the Highest Healing Potential—you get near- mid- and far-infrared, without the dangerous food heat lamps that many other infrared sauna companies use.
          • Safe and Certified by 3rdParties. Our saunas are backed by more safety certifications than any other sauna company.
          • Easy to Use. Setting up your infrared sauna in your home is WAY easier than other sauna brands. Any two people can do it, with just a screwdriver.
          • Heats Up Fast. With Finnmark Designs, you get the fastest heat-up times in the industry—under an hour up to 170° on a standard outlet. (Mini and Hybrid 2.0)
          • Comfortable and Relaxing. With whole-body therapy, you’ll feel the soothing heat throughout your sauna, with no cold spots—and special attention to the back, where 80% of Americans report pain and inflammation..
          • Backed by an Excellent Warranty. In the U.S., a “lifetime” warranty is considered 7 years, so don’t be fooled! Finnmark Designs has a warranty that covers your entire sauna for 10 years. Plus, our Spectrum Plus™ heaters are backed by an unconditional lifetime warranty—because we’re THAT confident in them.

          We manufacturer our infrared saunas in an actual sauna factory, not some furniture factory that builds couches and loveseats.  A factory that has decades of experience building infrared saunas.

          An Investment Towards Optimal Health

          Dr. Steve Masley

          An Investment Towards Optimal Health

          “Heating your core temperature is a powerful tool to enhance your health. It protects your heart, burns calories, and helps you sweat away toxins. INFRARED heat is the most comfortable way to accomplish this.

          Plus, you’re healing your skin, relaxing your muscles, producing ‘feel good’ endorphins, and getting a PASSIVE cardio workout!

          I love using my own sauna and believe it is an excellent investment towards optimal health.”

          Favorite Health Tool

          “Infrared sauna is my FAVORITE health tool. Everyone who gets one LOVES IT. Just sweat it out.

          Research Behind Saunas Is Strong

          “The research behind the health potential of saunas is strong.

          Heat stress activates a protein called FOXO3, which is known as the longevity gene.

          FOXO3 affects the immune function, DNA repair, alleviating pain, and STEM CELL activation!

          This is one wellness tool that does SO much for you, all in one.”

          Why Trust Finnmark Designs?

          • Backed by Certifications. Spectrum Plus Heaters are recognized by the prestigious Underwriters Laboratories. Saunas are ETL and CE certified. Plus, the cedar comes from a mill approved by the Forest Stewardship Council, ensuring forests will be around for generations to come. We use only dead trees—we never cut down living trees.
          • Excellent Warranties. Parts are NOT interchangeable between sauna brands, so you want to choose a company you can trust. Our factory has been manufacturing saunas for decades.
          • Upgraded Supplies. The power supplies and controllers we use are higher-end than other quality saunas. We upgraded capacitors, power relays, and wiring—these new materials should last 12-15 years. (Other saunas use parts that last 5-7 years.) The internal wiring is 14 AWG, and shielded to protect you—which makes the entire sauna low radiation instead of only the heaters.
          • Knowledgeable, Highly Trained Customer Service. The average number of years of sauna experience for people in our customer service department is 5 years.

          Best Investment for Health

          “Just three sessions a week for three months and my chronic neck pain is finally gone.

          I can say without a doubt that regular infrared sauna therapy was the best investment I’ve made for my health and the health of my family.

          It moved the mark on our health the fastest and most noticeable, more than anything we’ve done prior. It has exceeded my expectations.”

          Kelly R.

          Easy to Purchase & Use

          “The sauna was easy to purchase. Easy to put together. I have loved being able to use it in the privacy of my home.

          I have enjoyed my sauna more than I ever dreamed I would. It doesn’t take up much space, so if space is an issue you can still make it work. Because it is in my home, it is convenient and easy to use, and I can use it every day.

          It requires very little time and maintenance for care and cleaning. It is a wonderful aid for good health.”

          Linda M.

          Outstanding Materials & Craftsmanship

          “I use this sauna every night and love the improvement in my sleep. Because it takes away inflammation that can occur from running, I am able to work out the next day consistently without achy joints. My skin is so healthy and radiant since I began using the sauna.

          I like the integrity of the company, and the materials and craftsmanship they have chosen are outstanding. I feel it is an environmentally friendly and health-conscious product. Service from the sales staff was very helpful in choosing which unit would suit my needs.”
