About This Service

Full-Spectrum Heat for Deep Recovery

Royal Thai Spa features the Sunlighten Signature III — a clinically-backed full-spectrum infrared sauna that heats your body directly rather than the air around you. The result is a deeper sweat at a lower, more comfortable temperature than a traditional sauna.

Choose from seven preset wellness programs designed for specific goals: Detoxification, Relaxation, Anti-Aging, Cardiovascular, Weight Loss, Pain Relief, and Recovery. Each program adjusts the balance of near, mid, and far infrared wavelengths to target the right outcome.

Infrared sauna pairs beautifully with cold plunge for contrast therapy. The deep heat opens vessels and prepares the body, then the cold plunge amplifies the effects — reducing inflammation, accelerating recovery, and supporting the immune system.
