LumaPanel Full-Body Red Light Therapy Panel ($899 Value): The Relaxe Sauna combines 660 nm red light with 850 nm near-infrared wavelengths to support full-spectrum recovery routines. Red light may support collagen and skin clarity, while near-infrared penetrates deeper to support muscle recovery, help ease joint stiffness, and promote healthy circulation—within one dual-spectrum session. (Includes protective glasses. For best results, position yourself within 0–24" of the panel.)
Low EMF + Hemlock Frame + Tempered Glass Door: Built with an emphasis on safety and durability, featuring a Canadian hemlock frame (moisture-resistant, deformation-resistant) and a premium tempered glass door designed to retain heat and stand up to daily use. Low-EMF performance varies by configuration; always follow the included safety guidelines.
Far-Infrared Thermal System (9 Carbon Heaters): Far-infrared heat is delivered through 9 carbon heaters to create consistent, comfortable warmth. Additional heating zones under the bench and underfoot help deliver a more complete session for legs and feet. Customize your routine with 64–149°F temperature control and a 0–90 min timer.
Smart Controls + Immersive Sessions (Inside & Outside Panels): Dual control panels make it simple to adjust settings from inside or outside the sauna. Many configurations include modern convenience features like audio connectivity (e.g., Bluetooth) and device support. Features can vary by model/variant—please reference the specs listed on this product page.
Roomy, Ventilated, and Built for Real-World Use: The 1-person model measures 36" × 43" × 75" (L × W × H), and the 2-person model measures 47" × 43" × 75". A top vent supports airflow, and safety-first design choices help maintain a stable, comfortable environment during your sessions.
Chromotherapy Lighting + Built-In Convenience: Includes multi-color lighting modes designed to support a calming, spa-like atmosphere. Practical add-ons like storage and holders keep essentials within reach (towel, water, device, etc.). Exact accessories can vary by model—confirm what’s included for your selected option.
Delivery, Assembly & Returns (No Confusion):
Free in-home delivery to your door (up to the 2nd floor) with typical delivery in 5–7 business days. Your sauna ships flat-packed to fit through standard doorways, and most customers can assemble it with two adults in about ~45 minutes following the included guide.
Comprehensive 3-Year Warranty + Technician Support: Coverage on core components (heaters, electronics, and wood panels) with replacement parts and responsive, US-based support for three full years.
The Wellness Benefits Of Sauna Use
- Reduce Risk of Cardiovascular Disease and Mortality: Observational research has reported associations between regular sauna use and improved cardiovascular outcomes, including lower all-cause mortality and cardiovascular mortality. Infrared heat may increase heart rate and support circulation in a way that can resemble moderate activity.
- Accelerate Muscle Recovery and Pain Relief: Infrared heat may support blood flow and relaxation, which can help recovery routines after training and support comfort for muscle and joint stiffness. When combined with red light wavelengths (660/850 nm), many users report improved recovery quality.
- Boost Skin Health and Cellular Regeneration: Red and near-infrared wavelengths are commonly studied for collagen support and skin appearance. Consistent routines may support skin tone, elasticity, and the appearance of fine lines.
- Enhance Detoxification and Immune Support: Sweating is one path the body uses to eliminate certain compounds, and heat exposure may support lymphatic flow and recovery routines.
- Improve Longevity and Quality of Life: Some long-term observational studies suggest frequent sauna bathing is associated with improved health outcomes and quality of life markers.
- Relieve Stress and Promote Better Sleep: Heat exposure may promote relaxation and support better sleep quality by helping the body transition into a calmer state post-session.
- Support Metabolism and Weight Management: Infrared heat can elevate core temperature and may increase short-term energy expenditure; consistent routines may support broader wellness goals.
