About The Cal Spas

The Cal Spas story begins forty years ago at a crowded county fair. The year was 1978 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.

Signature Spas USA are manufactured with economical, energy-efficient methodologies. All of our hot tub and spa models include high-density foam insulation on the shell of the hot tub, as well as the closed cabinetry system which ensures the best level of insulation available. We offer, for colder climates, an economical thermal wrap upgrade that is rated for up to 30 degrees below 0! Additionally, most of our 220V models have at least one 2-speed pump that enables the tub to be put into a low-energy mode when it is not being used, which represents significant savings over hot tubs with single-speed pumps and circulating pumps.
