The Cal Spas story begins thirty years ago at a crowded county fair. The year was 1979 and California Acrylic Industries was a Pomona, California based pool builder in need of a way to exhibit a large variety of pool designs in a small space. To solve this dilemma, the company created small scale versions of its formed acrylic pools and put them on display for customers. The miniature pools sparked interest and the company began to receive special requests for acrylic hot tubs. A year later, with the company’s hot tub business growing, California Acrylic Industries took a leap of faith. The company stopped building pools and focused full-time on the hot tub business-and Cal Spas was born.
