This high-volume jet delivers a powerful massage for your lower back, or a pleasant swirling effect throughout your spa.

The Advent® control panel gives you command of the spa’s functions at your fingertips. An auxiliary control panel, on Utopia Series spas, lets you operate your spa’s components from a second location within the spa.

A patented system vents the heat produced by the pump motors out of the equipment area to create cooler operating conditions, prolonging the life of your Caldera spa’s components.

For a more powerful massage, simply adjust the diverter valves, directing water flow to the seats in use. Turn the outer ring on any adjustable jet or air valve to alter the flow, or close them off entirely to increase the massage action of jets you’re currently enjoying.

In the harsh outdoors, all hot tub components must be able to resist moisture and weathering. Our exclusive EcoTech® Cabinet offers the beauty of real wood with the durability and easy maintenance of rigid polymers. EcoTech has natural, embossed wood grains and is available in neutral Coastal Gray, rich Espresso, or natural Redwood.

Given the exposure of the interior spa shell to daily use, a quality construction and composition is critical. Our triple-layer DuraBond reinforcement system strengthens the tough acrylic surface for proven, time-tested performance.

Along with full-foam insulation, a Caldera cover provides a tight custom seal to reduce energy use. Made of a durable, marine grade-vinyl, it features child-resistant safety locks and conforms to all applicable ASTM safety standards.

All Caldera Spas feature FiberCor, an innovation that revolutionizes spa insulation. Applied at a 2lb, density, FiberCor is 4-times denser than typical 1/2lb. urethane foam
