Not All Saunas Are
Created Equal
Infrared saunas heat your body directly at the cellular level, delivering deeper therapeutic benefits at lower, more comfortable temperatures.
7x Deeper Detoxification
Infrared wavelengths penetrate 1.5 inches into tissue, mobilizing toxins stored in fat cells that traditional steam saunas simply cannot reach.
Accelerated Muscle Recovery
Deep infrared heat increases blood flow by up to 70%, delivering oxygen and nutrients to damaged tissue while flushing metabolic waste faster.
Passive Cardiovascular Workout
A 30-minute infrared session can burn 300-600 calories while raising your heart rate to a moderate cardio zone — all while sitting still.
Collagen & Skin Renewal
Near-infrared light stimulates collagen production and cellular regeneration, improving skin tone, elasticity, and reducing fine lines over time.
Sustained Energy & Mood
Infrared therapy triggers endorphin release and reduces cortisol levels, creating a natural energy boost without the crash of stimulants.
Lifetime
Heater Warranty
We stand behind every Onyx Series sauna with a lifetime warranty on all carbon fiber heater panels. No fine print, no expiration.
What Owners Are Saying
Frequently Asked Questions
Everything you need to know about our premium saunas
General Information
What are the health benefits of using a sauna?
Regular sauna use offers numerous health benefits including improved cardiovascular health, stress reduction, better sleep quality, and enhanced muscle recovery. The heat therapy helps increase circulation, promotes relaxation, and may support immune system function.
How often should I use my sauna?
For optimal benefits, we recommend using your sauna 3-4 times per week for 15-20 minute sessions. Beginners should start with shorter sessions and gradually increase duration as they become more comfortable with the heat.
What's the difference between infrared and traditional saunas?
Traditional saunas heat the air around you using heated stones, reaching temperatures of 150-195°F. Infrared saunas use light to directly heat your body at lower temperatures (120-140°F), making them more comfortable for longer sessions while still providing excellent health benefits.
Installation & Setup
Do I need special electrical requirements?
Most of our infrared saunas plug into a standard 120V outlet, making installation simple. Larger traditional saunas may require 220V electrical service. We provide detailed electrical specifications with each model and recommend consulting with a licensed electrician for installation.
How much space do I need for a sauna?
Space requirements vary by model. Our compact 1-person saunas need as little as 3' x 4' of floor space, while our largest 6-person models require approximately 7' x 7'. We recommend adding 6-12 inches of clearance on all sides for proper ventilation and access.
Can I install a sauna in my basement or bathroom?
Yes, our saunas can be installed in basements, bathrooms, bedrooms, or any indoor space with adequate ventilation and electrical access. Ensure the floor can support the weight and that there's proper ventilation to prevent moisture buildup.
Maintenance & Care
How do I clean and maintain my sauna?
Regular maintenance is simple: wipe down benches and walls with a damp cloth after each use, vacuum the floor weekly, and deep clean monthly with mild soap and water. Avoid harsh chemicals and always ensure the sauna is completely dry before the next use.
How long do infrared heaters last?
Our high-quality infrared heaters are designed to last 10,000+ hours of use, which typically translates to 15-20 years of regular home use. All heaters come with comprehensive warranties for your peace of mind.
What should I do if my sauna isn't heating properly?
First, check that the sauna is plugged in and the circuit breaker hasn't tripped. Ensure the door is properly closed and the temperature sensor isn't blocked. If issues persist, contact our technical support team for troubleshooting assistance.
Warranty & Support
What warranty do you offer on your saunas?
We offer a comprehensive warranty: lifetime warranty on the sauna structure, 5-year warranty on heaters and electrical components, and 1-year warranty on accessories. Our customer service team provides ongoing support throughout the warranty period.
Do you offer installation services?
Yes, we offer professional installation services in most areas. Our certified technicians ensure proper setup and provide a complete walkthrough of your new sauna. Installation typically takes 2-4 hours depending on the model.
How can I contact customer support?
Our customer support team is available Monday-Friday 8AM-6PM EST. You can reach us by phone, email, or live chat through our website. We also provide video support for technical troubleshooting when needed.
