The Caldera Difference

We create spas with a focus on
Comfort, Design and Performance

Our reliable, high-performance spas are designed for comfort, efficient energy use, and simple maintenance so you can enjoy the full wellness benefits that come from making a hot tub part of your daily routine.


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 can melt 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 colours 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.

Hot Tub Circuit Therapy™

Designed for Total Body Restoration

Each seat or position in a Caldera spa provides a deep massage to a different muscle group.
As you move from seat to seat, jets focus on those groups, one at a time.
