Peak Saunas — Full Spectrum Infrared with XL Red Light Therapy

Peak Saunas is a premium infrared sauna brand built around two core features: full spectrum infrared heating in every model and XL medical-grade red light therapy panels that are larger and more powerful than what most competing brands offer. Every Peak sauna also includes WiFi app control (iOS and Android via SmartLife), Bluetooth audio with dual speakers, chromotherapy lighting, and a limited lifetime warranty on heating elements and cabinetry. The lineup spans 1-person indoor cabins through 5-person outdoor saunas, with options in Canadian Hemlock and Canadian Red Cedar. Free shipping on every Peak sauna, 0% APR financing available.

Indoor Saunas

Shasta (PSS-1001-01) — 1-Person, Canadian Hemlock — Peak's flagship 1-person model and one of the best-reviewed infrared saunas in our catalog. Seven high-efficiency full spectrum infrared panels provide 360° heat distribution with a maximum temperature of 150°F — higher than the 140°F ceiling on most competing infrared saunas. The front-mounted XL medical-grade red light therapy panel emits 8 optimized wavelengths spanning 590nm to 940nm, covering visible red through near-infrared for the broadest therapeutic range available in a built-in sauna panel. Sustainably sourced Canadian Hemlock construction. Plugs into a standard 120V outlet.

Rainier (PSR-1001-01) — 1-Person, Canadian Red Cedar — The same 7-panel full spectrum heating system and XL red light therapy as the Shasta, built in No-VOC premium Canadian Red Cedar instead of Hemlock. Cedar adds a natural aromatic scent and warmer visual character — a luxury upgrade for buyers who want the classic cedar sauna experience combined with Peak's full feature set. Same 150°F max temperature, WiFi control, and 120V plug-and-play operation.

Olympus — 1-Person, FAR Infrared — Peak's entry-level model. FAR infrared panels (not full spectrum) with WiFi app control but without the XL red light therapy panel found on the premium models. A more affordable entry point into the Peak ecosystem for buyers who want WiFi control and Peak build quality but don't need full spectrum or red light.

Fuji (PSF-2001-01) — 2-Person — Peak's spacious 2-person model with a distinguishing feature: a 45-degree angled near-infrared heater positioned for targeted front-body heat. This directed panel angle is rare in residential infrared saunas and improves near-infrared exposure to your chest and torso during sessions. XL red light therapy panel, WiFi control, full spectrum heating. Shop all full spectrum infrared saunas.

Everest (PSE-2001-01) — 2-Person — Peak's 2-person smart sauna with 8 full spectrum infrared panels (one more than the 1-person models) for enhanced heat coverage with two users. Canadian Hemlock construction, XL red light therapy, WiFi app control, 150°F max temperature. If you want a 2-person Peak sauna without the Fuji's angled panel design, the Everest is a straightforward full-featured choice.

Matterhorn (PSM-3001-01) — 3-Person — Peak's largest indoor model with dual red light therapy panels for increased coverage across a wider cabin. Full spectrum infrared heating, WiFi control, and enough bench space for three people or for stretching out solo. Shop all red light therapy saunas.

Outdoor Saunas

El Capitan (PSC-4001-01) — 4-Person Outdoor — Peak's outdoor architectural sauna designed for permanent backyard placement. Full spectrum infrared panels, weather-resistant construction, and the same WiFi control and smart features as the indoor lineup. A premium outdoor infrared option for buyers who want Peak's technology in an outdoor setting.

Kilimanjaro (PSK-5001-01) — 5-Person Outdoor — Peak's largest model with commercial-grade performance in a 5-person outdoor cabin. Built for heavy residential use or commercial settings like wellness centers, spas, and gyms. Full spectrum infrared, WiFi control, and construction designed to handle year-round outdoor exposure.

XL Red Light Therapy — What Makes It Different

The XL medical-grade red light therapy panel is Peak's biggest differentiator. While brands like Dynamic (Elite models) and Finnmark Designs include red light panels in their saunas, Peak's panels are physically larger and emit 8 optimized wavelengths spanning 590nm to 940nm — a broader range than most competing built-in panels. The panel is front-mounted on the door or front wall, positioning it directly in front of your face, chest, and torso during sessions for maximum skin and tissue exposure.

Red light therapy in the 600–900nm range is used for skin health and collagen production, muscle recovery and inflammation reduction, wound healing and cellular energy production, and joint pain relief. Running red light simultaneously with infrared heat is more effective than either therapy alone — the infrared heat increases blood flow and dilates blood vessels, which helps your cells absorb more of the therapeutic light wavelengths. If red light therapy is a primary purchase driver, Peak offers the most built-in RLT coverage of any brand we carry.

Frequently Asked Questions

Which Peak sauna should I buy?

For a single user who wants the full Peak experience at the best value, start with the Shasta (Hemlock) or Rainier (Cedar) depending on your wood preference. For two people, the Fuji offers the unique angled near-infrared panel, while the Everest is a more traditional layout with an extra heating panel. The Matterhorn is the largest indoor option with dual red light panels. If budget is the main concern and you don't need full spectrum or red light, the Olympus is Peak's most affordable entry point. Our Peak Saunas review covers each model in detail.

Do Peak saunas plug into a standard outlet?

The indoor models (Shasta, Rainier, Olympus, Fuji, Everest, Matterhorn) plug into a standard 120V household outlet — no electrician or dedicated circuit required. Check the specific product page for the outdoor models (El Capitan, Kilimanjaro) as electrical requirements may differ.

How does Peak compare to Finnmark Designs?

Finnmark Designs is the closest competitor to Peak in the premium infrared space. Both offer full spectrum infrared, red light therapy (in hybrid saunas), and WiFi control as standard. Peak's advantage is their XL medical-grade red light panels — physically larger with a broader 8-wavelength spectrum (590–940nm). Finnmark's advantage is the Trinity hybrid line that combines infrared with a traditional electric heater for steam, which Peak doesn't offer. If red light therapy is your top priority, Peak wins. If you want the option to do both infrared and traditional steam in one unit, Finnmark's Trinity is the only choice.

How does Peak compare to Dynamic and Maxxus?

Dynamic and Maxxus are mid-range brands from Golden Designs, Inc. — they offer more models at lower price points but with fewer standard features. Full spectrum and red light therapy are upgrade tiers on Dynamic and Maxxus (you pay more to get them), while they're standard on every Peak sauna. Peak also offers a higher max temperature (150°F vs. the typical 140°F) and the XL red light panel. The tradeoff is price — Peak saunas cost more than equivalent-size Dynamic or Maxxus models. For a full comparison, browse our infrared sauna collection.

What warranty do Peak saunas include?

Every Peak sauna includes a limited lifetime warranty covering heating elements (lifetime, defined as 7 years under normal residential use) and cabinetry/wood structure (lifetime, defined as 7 years). This is among the strongest warranties in the infrared sauna market. The warranty applies to original purchases from authorized dealers, and Peak provides lifetime USA-based customer support.
