Osmosis is the only day spa in the U.S. that offers the Cedar Enzyme Bath, a rejuvenating heat treatment from Japan. Inspired by a vision of healing, beauty, and inner peace, Osmosis was founded in Sonoma County in 1985. Since that time, many hands have worked together with an abundance of heart to manifest one of the most unique and relaxing spas in the country.
Our LocationLocated on five secluded acres in a scenic valley 1.5 hours north of San Francisco, Osmosis is a Japanese-style retreat with beautiful bonsai and bamboo gardens. Close to Northern California's breathtaking Sonoma Coast, wine country and redwoods, Osmosis is situated in a great destination spot with superb lodging nearby and many activities to choose from.
The Osmosis staff has worked hard to create a healing environment with attention to detail and aesthetics. A talented coterie of massage therapists has crafted their art into a style that combines wonderfully with the Cedar Enzyme Bath. The cornerstone is shared vision and meaningful work.
