The Cal Spas story began 1978 at a crowded county fair. The California Acrylic Industries was a Pomona, California-based pool builder searching for a way to exhibit a large variety of pool designs in a small space. To solve this dilemma, the company created smaller versions of its formed acrylic pools and put them on display for customers. The miniature pools immediately 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. Cal Spas was born. Cal Spas current headquarters grew into a 1-million square foot State-of-the-Art manufacturing plant in Pomona, California. Today, the celebrated hot tub maker is world renowned as the #1 Global Manufacturer of Home Resort Products. Cal Spas produces premium collections of products from its headquarters in Pomona, California and distributes worldwide through a network of specialty dealers.
