SEATS & JETS
Take a seat. You’ll immediately feel the Caldera difference, thanks to unique, body-hugging contours and ergonomically designed configurations. Utopia Series spas take jet massage to a new level with added hip, wrist and neck jets for a full body experience.
HOT TUB CIRCUIT THERAPY®
The Cantabria features more targeted massage seats than any other Caldera spa. As you move from seat to seat in the Cantabria, you’ll experience a full body massage, with jets that focus on your neck, shoulders, upper back, mid back, lower back, hips, thighs, calves, feet and wrists.

FRESHWATER® IQ SYSTEM
Our innovative water care system automatically generates the perfect amount of chlorine, uses smart monitoring technology to test your water every hour and provides clear instructions if adjustments are needed.
ENERGY EFFICIENCY
In addition to the energy saving features built into every Caldera spa, the Utopia Series features a thermal isolated base pan that beautifully frames the bottom of the spa while minimizing ground contact and improving energy efficiency.
The EnergyPro circulation pump in our Utopia Series spas saves you money by operating at a very low wattage to filter water. Heater use is reduced, as energy used to operate the pump is transferred back to the water as heat.
ECOTECH® PLUS CABINET
Our premium cabinet includes a modern black header, wood grain accent, stainless-steel trim and integrated LED light bar that will complement any backyard aesthetic.
LIGHTING
Create a special ambiance with the adjustable SpaGlo® lighting system that accents individual zones throughout the spa, such as bar top, footwell, waterfall and exterior corners.
TOUCHSCREEN CONTROL
Your daily hydrotherapy experience is easily managed with our intuitive Advent control panel which gives you complete control over water temperature, jet systems and ambient lighting effects.
The Hot Spring® Spas App, powered by the Connected Spa Kit allows you to control and monitor your spa from home or on the go.
Patented cover lifters make opening and closing the spa cover simple, helping maintain the life of your cover.
An optional Bluetooth® music system can be added for streaming high-quality sound to your spa.
Designed to match the spa cabinets, steps help you more confidently move in and out of your spa.
