Begin your Osmosis journey with an authentic Japanese tea ceremony in a private room overlooking our breathtaking koi pond and zen garden.
Every Osmosis experience begins the same way — with stillness. Guests are welcomed with traditional Japanese tea served in a private room that looks out over our stunning koi pond, Japanese garden, and the lush Sonoma County hillside.
This isn't just tea. It's a conscious transition from the pace of everyday life into a space of genuine tranquility — a ritual that has grounded the Osmosis experience since our founding and sets the tone for everything that follows.
The Japanese tea service at Osmosis is an integral part of the overall spa experience — not an add-on or an afterthought. It is the opening chapter of your visit, designed to quiet the mind and prepare the body for what comes next.
Sip warm tea as you gaze out over the garden. Watch the koi move through the still water. Let the outside world fade. By the time you move into your cedar bath or massage, you're already halfway there.
All Spa Packages — from $127.50 per person
Cedar Enzyme Bath — from $155

Leave the world behind. You're guided to your private tea room overlooking the garden and koi pond.
Sip traditional tea in silence or quiet conversation as you settle into the tranquility of the Osmosis grounds.
Move into your cedar bath, massage, or facial — body and mind already calm and fully receptive.
After your treatment, wander the zen gardens, meditation spaces, and koi pond at your own pace.
There is no other Japanese tea ceremony experience quite like this in Sonoma County. Osmosis in Freestone offers a genuine, immersive setting that transports you — something you simply cannot find at a typical Santa Rosa spa.
Guests travel from Santa Rosa, Petaluma, Sebastopol, and the wider Bay Area specifically for the Osmosis experience. The scenic 45-minute drive from Santa Rosa is itself part of the journey.
