Clearlight Saunas (sold through Heal With Heat) has been manufacturing infrared saunas since 1997. They're one of the original players in the space and have built significant credibility with health practitioners and wellness enthusiasts.
Peak Saunas entered the market more recently with a direct-to-consumer model and a unique combination of full-spectrum infrared plus integrated red light therapy.
Let's break down exactly how these two brands compare—no marketing spin, just facts that help you make an informed decision.
Side-by-Side Comparison
| Feature | Peak Saunas | Clearlight |
|---|---|---|
| Full-Spectrum Infrared | ✅ Yes | ✅ Yes (Sanctuary models) |
| Medical-Grade Red Light Therapy | ✅ Built-in | ❌ Optional add-on |
| Near-Zero EMF | ✅ Yes | ✅ Yes (Low EMF focus) |
| Price Range | $4,950-$10,250 | $5,449-$9,999+ |
| Warranty | Lifetime | Lifetime |
| Sales Model | Direct-to-consumer | Dealer network |
| Assembly | DIY (45-60 min) | Professional available |
Understanding Clearlight's Product Line
Clearlight offers several model lines with different technology:
Clearlight Essential Series: Far-infrared only (not full-spectrum). Entry-level pricing around $3,999-$4,999.
Clearlight Sanctuary Series: Full-spectrum infrared with True Wave™ heaters. Premium pricing around $6,499-$9,999+.
Clearlight Premier Series: Far-infrared with some full-spectrum options. Mid-range pricing.
When comparing to Peak Saunas, you need to compare the Sanctuary Series specifically—that's where Clearlight offers full-spectrum technology comparable to Peak's standard offerings.
Full-Spectrum Technology
Both Peak and Clearlight's Sanctuary models deliver near, mid, and far infrared wavelengths:
Near Infrared: Promotes skin rejuvenation and surface-level healing Mid Infrared: Supports pain relief and improved circulation Far Infrared: Facilitates deep detoxification and core body temperature elevation
Clearlight's True Wave™ heaters are well-regarded in the industry. They've invested heavily in heater technology and have documentation supporting their infrared output.
Peak Saunas uses high-quality carbon heaters with proven emissivity ratings. Both brands deliver therapeutic infrared exposure across the full spectrum.
Key difference: All Peak Saunas full-spectrum models include this technology standard. With Clearlight, you need to buy the Sanctuary series specifically—their entry-level Essential line is far-infrared only.
Red Light Therapy: A Significant Differentiator
This is where Peak Saunas offers something Clearlight doesn't match.
Peak Saunas integrates medical-grade red light therapy panels directly into their full-spectrum models. This isn't an afterthought—it's full-body coverage using clinically relevant wavelengths (typically 630-660nm red and 830-850nm near-infrared).
What red light therapy adds: - Mitochondrial function and cellular energy (ATP) - Collagen production and skin elasticity - Inflammation reduction - Muscle recovery acceleration - Joint health support
Clearlight does offer a red light therapy add-on option, but it's additional cost and not the same integrated experience. You're essentially adding a separate device to your sauna rather than having a purpose-built combination unit.
Cost impact: Peak includes red light therapy at no additional cost. Clearlight's add-on options can run $1,000-$2,000+ on top of already premium pricing.
The EMF Question
Clearlight has historically marketed heavily around EMF (electromagnetic field) levels, positioning their saunas as "low EMF" or "near-zero EMF."
Let's be clear about EMF: The World Health Organization has reviewed the scientific evidence and concluded that the EMF levels produced by household electronics, including infrared saunas, are not a health concern. The amounts we're talking about are far below levels that cause any documented biological effects.
Both Peak Saunas and Clearlight produce saunas with low EMF readings—this is standard in quality infrared sauna construction today. It's achieved through proper heater design and positioning.
Peak Saunas doesn't heavily market EMF because the science doesn't support it as a meaningful differentiator. We build low-EMF saunas because that's responsible engineering, not because it's a selling point that matters.
If EMF is a genuine concern for you, both brands will deliver acceptable levels. But it shouldn't be a primary factor in your decision.
Price Comparison: Where Your Money Goes
Clearlight Sanctuary Series (Full-Spectrum): - Sanctuary 1 (1-person): ~$6,499 - Sanctuary 2 (2-person): ~$7,599 - Sanctuary 3 (3-person): ~$8,999 - Sanctuary Y (4-person yoga): ~$10,499+
Peak Saunas (Full-Spectrum + Red Light Therapy):
- Olympus/Aspen 1-Person: $4,950-$5,150
- Crown/Sierra 2-Person: $5,950-$6,098
- Everest/Fuji 2-Person: $7,450-$7,950
- Denali/Matterhorn 3-Person: $9,250-$10,250
While Clearlight's Sanctuary series starts higher, Peak's pricing reflects for comparable sizes, and Peak includes red light therapy that Clearlight charges extra for.
Why the difference?
Clearlight sells through a dealer network. Showrooms, sales commissions, and retail markup add cost that ultimately comes from your wallet. That's not wrong—it's just a different business model.
Peak Saunas sells direct. No middlemen. Lower overhead. Those savings go directly to you as a better price.
Warranty Comparison
Both brands offer lifetime warranties, which is a strong signal of confidence in their products.
Peak Saunas: Lifetime warranty on structure, heaters, and electrical components.
Clearlight: Lifetime warranty on heaters and structure. Electrical components and accessories may have different coverage periods depending on the model.
Read the fine print on any warranty, but both brands stand behind their products long-term.
Build Quality and Materials
Peak Saunas: - Canadian Hemlock or Western Red Cedar options - Tempered glass doors - Tongue-and-groove construction - Interior LED lighting - Bluetooth speakers - Smart WiFi app control
Clearlight: - Eco-certified wood options (Basswood, Cedar) - Tempered glass doors - Tongue-and-groove construction - Interior lighting - Audio system - Medical-grade chromotherapy
Both brands build quality saunas. Clearlight has been doing it longer, but Peak's construction is at the same level—we wouldn't ship anything less.
Clearlight offers more customization options through their dealer network. If you want specialized configurations, that's worth exploring. Peak offers a streamlined product line focused on the most popular configurations.
Customer Experience
Peak Saunas: - Order online, direct from manufacturer - Free shipping nationwide (freight to your door) - Assembly: 45-60 minutes, no tools, 2 people - Direct US-based customer support - Peak Wellness Club membership included
Clearlight: - Purchase through authorized dealers - Delivery and assembly options vary by dealer - Professional installation available (additional cost) - Support through dealer network - Various financing options through dealers
With Peak, you're dealing with one company from purchase through support. With Clearlight, your experience depends on which dealer you work with—some are excellent, others may be inconsistent.
The Peak Wellness Club is a unique inclusion: guided sauna protocols, community access, and ongoing wellness education at no additional cost. This helps you actually use your sauna effectively rather than just owning it.
Who Should Choose Clearlight?
Clearlight makes sense if: - Brand longevity (27+ years) is important to you - You want to see saunas in person at a local showroom - You prefer professional installation and want someone to handle everything - EMF marketing resonates with your concerns - Budget isn't a primary constraint - You don't need integrated red light therapy
Clearlight has a track record and dealer presence that some buyers value. If you want the "see it, touch it, have someone install it" experience, their dealer network provides that.
Who Should Choose Peak Saunas?
Peak Saunas makes sense if: - You want full-spectrum infrared AND red light therapy built-in - Value matters—you want premium technology without the premium markup - Direct-to-consumer transparency appeals to you - You're comfortable with straightforward self-assembly - Lifetime warranty is important - You want access to the Peak Wellness Club community
The combination of full-spectrum infrared plus medical-grade red light therapy at a $3,000-$5,000+ savings is the core proposition. You're getting more technology for less money.
The Bottom Line
Both Peak Saunas and Clearlight produce quality infrared saunas that will deliver genuine health benefits. This isn't a "bad choice vs. good choice" comparison—it's about what fits your priorities.
Choose Clearlight if: Showroom experience, professional installation, and brand heritage matter more than price efficiency.
Choose Peak Saunas if: You want the most technology (infrared + red light) for the best price with direct manufacturer support.
For most buyers focused on results per dollar, Peak Saunas delivers better value. You get full-spectrum infrared, integrated red light therapy, lifetime warranty, and the Wellness Club—at thousands less than Clearlight's infrared-only Sanctuary models.
The savings could fund additional wellness investments: supplements, gym memberships, massage, or simply stay in your bank account.
