The uniquely contoured seats on every Caldera Spa hot tub let you relax in unmatched comfort. Enjoy the hydrotherapy benefits without struggling to resist the effects of bouyancy. When the powerful jets are off, you’ll simply relax in the spacious interior, designed to cradle you in comfort you can really feel.

Energy Efficient Hot Tub

With its exclusive and highly efficient EnergyPro circulation pump, your Caldera spa is always hot and ready to use while meeting the most stringent energy efficiency
standards established for portable spas. The system operates at very low wattage to filter water and actually reduces heater use since 80% of the energy used to operate it is transferred to the water as heat.

Enjoy the comfort of knowing your Caldera EnergyPro heater, a highly efficient system that filters water continuously to keep it clean, is backed by an unconditional limited warranty. 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.

Easy Water Care

We know you don’t want to handle messy water chemicals so we offer a simple water care system called the FROG® as a standard feature on all Caldera Spas. The system makes it easy for you to manage the infrequent replacement of bromine and mineral cartridges so you can enjoy sparkling clear spa water every time you dip into your Caldera hot tub.

One Touch Controls

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.

Reduce Energy Use

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.

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.
