Cal Spas – America’s premier hot tub brand, crafting comfort since 1978

Cal Spas began in 1978 at a Pomona county fair when California Acrylic Industries, a local pool builder, displayed miniature versions of its pools. The exhibit drew interest in hot tubs, inspiring a full shift to spa production—and Cal Spas was born. What started with a few models soon expanded nationwide, leading to today’s 40-acre headquarters in Pomona, California, built on craftsmanship, quality, and innovation.
