Caldera® Spas Comfort

Why Comfort 
is important to you in a hot tub

Designing a spa for Pure Comfort® is about more than just making you feel good. It's about helping you relax completely, putting you in a place where you can leave stress behind and recharge.

Key Comfort Features

Our designers have created ergonomically sculpted seats that comfortably cradle you, decompress your spine, and keep you aligned. Combined with the buoyancy of the water, the seat's design releases pressure off parts of the body that are under stress all day.

Personalized Massage

Easily direct or increase water flow to the seats you choose with the diverter valves located around the Utopia® and Paradise® Series spas. Adjust the strength and flow of many individual jets to your preference by simply turning the air valves or outer ring around individual jets.

A Caldera spa is carefully and purposely designed with a variety of jet types, strategically placed to deliver just the right type of massage right where it's needed—whether it's your aching lower back or the soles of your feet.

Hot Tub Circuit Therapy®
Designed for Total Body Restoration

When you workout in a gym with a personal trainer, he or she will create a plan that moves you from station to station with different exercises to give you a balanced, full-body workout that emphasizes all major muscle groups.

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, including your neck and shoulders, the large muscles of your back, lower back, hamstrings, calves and feet.

Rotate through the circuit for total-body restoration, or just concentrate on the areas that need the most attention. A Caldera spa is yours to personalize as you see fit.
