Ganbanyoku is a Japanese word meaning ‘stone bath.’ At SpaPure, we call it a granite sauna. Wearing comfortable, loose clothing or a towel, you’ll lie under an herbal steam dome on a slab of specially quarried Indian granite. The stone is gently warmed to 103 degrees, releasing a very safe far-infrared energy that increases blood circulation and produces a deep, profuse sweat that flushes out toxins. Proponents say ganbanyoku also stimulates your skin’s own production of youth-enhancing collagen. Ganbanyoku’s immediate results are undeniable: a clean, non-sticky sweat that you don’t need to shower off, a softening of formerly stiff muscles, and skin that’s radiant, smooth and shiny.
