Clearlight Sanctuary™ 2 Infrared Sauna Review

If you’re like most people researching home saunas, you’ve probably spent hours comparing brands, reading specs, and wondering whether a full-spectrum infrared sauna is worth the investment.

I get it. With prices ranging from $6,000 to $7,500, the Clearlight Sanctuary™ 2 Infrared Sauna isn’t a casual purchase.

After diving deep into the specifications, customer feedback, and clinical research behind infrared therapy, I’ve put together this honest review to help you decide if this two-person sauna fits your wellness goals and budget.

Product Overview

The Clearlight Sanctuary™ 2 Infrared Sauna is a full-spectrum infrared sauna designed for two adults, featuring Clearlight’s patented True Wave™ heating technology that delivers near, mid, and far infrared wavelengths simultaneously.

Unlike traditional saunas that heat the air, infrared saunas use light waves to warm your body directly at lower ambient temperatures (typically 120–140 Fahrenheit), making sessions more comfortable for people who struggle with extreme heat.

This model stands out for its low EMF/ELF emissions, smartphone app control, and furniture-grade wood construction available in mahogany or basswood.

Clearlight has been manufacturing infrared saunas since 1997 and has sold over 85,000 units across the U.S., with the Sanctuary series representing their flagship full-spectrum line.

Key Features and Benefits

True Wave™ Full Spectrum Heating System

The Sanctuary 2 uses a combination of carbon and ceramic heaters to deliver all three infrared wavelengths (near, mid, and far) throughout your entire session.

Two 500W full spectrum heaters on the front wall target your face and upper body
Far infrared heaters positioned on the back wall, side walls, behind your calves, and under the floor provide 360-degree coverage
This hybrid design aims to maximize tissue penetration and therapeutic benefits compared to far-infrared-only saunas

Full-spectrum infrared may offer advantages for skin health, cellular repair, and deeper heat penetration, though research is still emerging in this area.

Low EMF/ELF Technology

Clearlight claims their heaters produce less than 1 milligauss of electromagnetic field (EMF) exposure at typical seated distance, achieved through proprietary winding design that cancels opposing magnetic fields.

If you’re sensitive to EMF exposure or plan to use your sauna daily, this could be a meaningful differentiator compared to budget brands that don’t address EMF levels.

Smartphone App Control

The digital control system works with a tablet/smartphone app, allowing you to:

Start preheating your sauna remotely before you arrive home
Adjust temperature and session duration from your phone
Control chromotherapy lighting and audio systems

This convenience feature might matter if you want to maximize your limited relaxation time.

Lifetime Warranty

Clearlight offers a lifetime warranty on heaters, wood, and electrical components for residential use—one of the strongest warranty packages in the infrared sauna industry.

This could provide peace of mind given the significant investment, though some customers report mixed experiences with warranty claim response times.

Pros and Cons

Based on product specifications, customer reviews, and third-party testing, here’s what stands out about the Clearlight Sanctuary 2:

Things We Liked:

Full-spectrum infrared heating with near, mid, and far wavelengths for comprehensive therapeutic coverage
Industry-leading low EMF/ELF emissions (under 1 mG) verified by third-party testing
Lifetime warranty on heaters, wood, and electrical components—one of the best in the industry
Smartphone app control allows remote preheating and session customization
Furniture-grade wood construction (mahogany or basswood) with natural grain variations
Backed by clinical studies from universities including Binghamton and Loras College
Two 500W front-wall full spectrum heaters provide targeted facial and upper-body heating
Company has 25+ years in business with 85,000+ saunas sold since 1997

Things We Didn’t Like:

Premium pricing ($6,000–$7,500 range) may be prohibitive for budget-conscious buyers
Some customers report long wait times for replacement parts and slow warranty claim responses
Requires dedicated 20-amp circuit, which may need electrical upgrades in older homes

Verdict

The Clearlight Sanctuary 2 delivers on its core promises: full-spectrum heating, validated low EMF levels, and durable construction backed by a lifetime warranty.

However, the premium price point and occasional customer service delays mean it might not be the best fit for everyone.

Research from Binghamton University found that participants using Clearlight infrared saunas three times per week for 30 minutes lost an average of 4% body fat over four months, while a Loras College study showed significantly improved blood lactate recovery after maximal aerobic exercise.

Who Is This Product For? Personal Opinion

The Clearlight Sanctuary™ 2 Infrared Sauna might be a good choice if:

You want a full-spectrum infrared sauna with near, mid, and far wavelengths for comprehensive therapeutic benefits
Low EMF/ELF exposure is a priority for you or your family members
You plan to use your sauna regularly (3+ times per week) and want a lifetime warranty for long-term peace of mind
You have space for a two-person unit (roughly 4 feet by 4 feet footprint) and access to a dedicated 20-amp electrical circuit
You value smartphone app control and remote preheating convenience

This might not be the best fit if you’re on a tight budget, need a smaller one-person sauna, or prefer traditional high-heat steam saunas.

FAQ & Additional Tips

How much does the Clearlight Sanctuary 2 cost?

How do I use the Clearlight Sanctuary 2?

Start with 10–15 minute sessions at lower temperatures (100–120 Fahrenheit), gradually increasing to 20–30 minutes at 120–140 Fahrenheit as your body adjusts. Stay hydrated before, during, and after sessions.

What is the warranty and guarantee?

Clearlight offers a lifetime warranty on heaters, wood, and electrical components for residential use. Commercial use is covered under a separate, shorter warranty structure.

Final Verdict

After reviewing the specifications, clinical research, and customer feedback, the Clearlight Sanctuary™ 2 Infrared Sauna earns a solid recommendation for buyers who prioritize full-spectrum heating, validated low EMF levels, and long-term durability.

The lifetime warranty, smartphone app control, and furniture-grade wood construction justify the premium price for many users, especially those planning daily or near-daily sessions.

However, if you’re budget-conscious, need faster customer service response times, or prefer traditional high-heat saunas, you might want to explore alternatives in the $3,000–$5,000 range.

If the Sanctuary 2 aligns with your wellness goals and you’re ready to invest in a long-term home sauna, it could be worth checking out.
