The Caldera Difference


Comfort is the essential element in our hot tubs. Deep, cradling seats and a textured Foot Ridge® help you stay relaxed and seated even when enjoying powerful jets. Perfectly positioned hydrotherapy massage melts your tension away. And a whisper-quiet sound dampening design enhances the comfort experience.


We craft each hot tub detail to awaken the senses. From rich colors and contemporary cabinet styles to the organic contours of our sculpted seats, every element is intended to soothe and delight.


To get the most out of your spa, it needs to operate at a consistently high level. Each Caldera hot tub is engineered and built with the strictest attention to quality and efficiency. Our commitment is your assurance of reliable, energy-efficient performance for years of worry-free hot tubbing.

Energy Efficiency

At Caldera® spas, we don't compromise when it comes to energy efficiency. Each of our hot tubs meets the most stringent energy standards established by the California Energy Commission (CEC). Every aspect of your spa's construction - insulation, heaters, pumps, and even our spa covers - work together to keep your spa water hot, and your energy bills low.

Circuit Therapy

Caldera hot tubs are designed specifically to deliver a full-body massage. It's an innovative design idea called Hot Tub Circuit Therapy and it's patterned after circuit weight training where you move from station to station, performing different exercises that help you work all your major muscle groups.

Caldera® Spas was founded in 1976 and is one of the most heralded and trusted spa brands in the world. Caldera is manufactured by Watkins Wellness—the global industry leader having built more than one million hot tubs.

Caldera spas are recognized throughout the industry for performance, quality, and customer satisfaction. Recent awards and recognition include receiving thirteen consecutive certifications for excellence in customer satisfaction from the consumer group SpaSearch.

FreshWater IQ System

FreshWater IQ is an in-line, self-monitoring salt system that tells you what it needs to maintain clean, natural-feeling water, with less time and effort. Because we believe your hot tub should take care of you, not the other way around.

How It Works:
Salt System + Smart Monitoring System

The Salt System automatically generates chlorine from salt to keep your spa water feeling naturally fresh and ready to enjoy.

The Smart Monitoring System automatically tests your water every hour and provides clear instructions when adjustments are needed for clean water.
