We are the authorized dealer for Dimension One Spas , Clearwater Spas, Artesian Spas and redwood hot tubs for Marin, Sonoma, Napa, Contra Costa, Solano, Lake and Mendocino counties. By bringing you four hot tub lines, we can offer more choices and flexibility in options, features and designs. Our hot tub manufacturers have been making hot tubs for a combined 80+ years in the United States. They each have excellent tech support, very responsive customer service and top quality control.

Our manufacturers use a Green approach to building their hot tubs. They use recycled high impact resistant plastics that are designed to withstand the harsh elements that mother-nature will punish your outdoor appliance with. They use sealed ABS pan bottoms so rodents don’t get in and destroy your frame, plumbing and electrical. These hot tubs are properly designed to last twice as long as your average hot tub or longer for the same price or less! All of our manufacturers have passed the stringent California Energy Title 20 requirements.
