El Capitan 4-Person Outdoor Full Spectrum Infrared Sauna with Full-Body Medical-Grade Red Light Therapy and Smart WiFi App Control

El Capitan — The 4-person outdoor flagship.

The El Capitan is our outdoor flagship — a weatherproof four-person cabin with thirteen heating panels, two medical-grade red-light panels, full-spectrum infrared, and a true 170°F. The most complete sauna we build.

Included free with every El Capitan

• Lifetime Peak Wellness Club membership — $588/yr value. Guided daily sessions, 30-day programs, an expert research library, and session tracking — free for life.
• Free delivery, shipped in a custom protective crate.
• Lifetime warranty + lifetime U.S.-based support.
• $3,598 value — two medical-grade red-light panels, included standard.
• Peak Welcome Box to start your practice from day one.

Medical-grade red light, where it works. Two medical-grade red-light panels across the front wall — not a decorative strip — positioned for full-body coverage while seated, and designed to support skin, circulation, and recovery.

360° full-spectrum infrared heat. A hybrid of carbon FAR panels plus halogen + quartz emitters delivers near, mid, and far wavelengths (700–25,000nm) for even, full-body warmth — built to support deep relaxation and recovery.

A true 170°F. Reaches a true 170°F — well beyond the 140°F ceiling of most infrared saunas — for a deeper, more satisfying sweat.

Run it from your phone. Preheat from anywhere; adjust temperature, lighting, and session length in the Peak Saunas app (iOS & Android).

An atmosphere for the ritual. Two HiFi Bluetooth speakers, dual-level LED accent lighting, built-in chromotherapy, and a smart oxygen-ionization system that freshens the air during and after each session — plus a foot-reflexology heater for head-to-toe warmth.

Built to last. Weatherproof cabinetry built for year-round outdoor use, in hand-finished Canadian hemlock — non-toxic and naturally durable. Clasp-together assembly. Ultra-low-EMF construction throughout. Installs on a dedicated 240V circuit (professional installation recommended).
