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.
We’re committed to energy-efficient design as a way to save energy and save you money on operating costs. From our innovative FiberCor® cabinet insulation to our highly efficient EnergyPro® system to custom-fit covers, a Caldera spa meets the most stringent energy efficiency standards established for portable spas. And that saves you money.
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 the Vacanza® Series. 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.
Heaters, pumps and other components are designed so they’re more efficient, robust and longer-lasting.
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 from ground zero. Stress can negatively affect your immune system, your social interactions and your health in general. The ability to fully let go, to completely power down, is so vitally important to your overall well-being. So, yes, we take comfort very seriously.
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.
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 force all day. Our seats are also designed in a way that help keep the water’s buoyancy from floating you out of the seat. After all, it’s hard to relax when you’re fighting the water to stay in place. There’s also a Foot Ridge® unique to Caldera® spas that helps keep you stable in your seat even when the jets are at their highest setting.
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 melts your tension away. And a whisper-quiet sound dampening design enhances the comfort experience.
A spa’s warm water massage promotes healing by increasing circulation, carrying nutrients to help cells and tissue regenerate. According to the textbook Comprehensive Aquatic Therapy by industry experts Dr. Bruce Becker and Dr. Andrew Cole, immersion in warm water is a “unique healing environment” that can lead to temporary relief from muscle aches and pains.
The immediate allure and beauty of the Vacanza® Series comes from its EcoTech® all-climate cabinetry. EcoTech cabinet, offers a contemporary design that is extremely durable it resists rotting, and is warrantied not to crack, split, or chip. It’s a gleaming, high-strength material that gives the spa it’s contemporary look and fluid impression. The transformed Vacanza design features a new vision of the spa shell design, one that’s minimal, elegant, and contemporary. Its curved lines add to the spa’s beauty with an uplifting impression.
The Vacanza® Series spas represent our most innovative approach to design, performance, and comfort with features that are simply unlike any other spa available today. With it’s stunning multi-dimensional EcoTech® all-climate cabinet and elegant new shell design, the Vacanza Series will captivate you.
Accessorize your Caldera hot tub with a wide range of options that make your spa uniquely yours. Choose from an array of conveniences including steps, cover lifters, hand rails, umbrellas and hydro massage jet kits all designed to help you relax and enjoy your own private retreat.
Music has the ability to enhance or create nearly any mood. For the ideal setting in or around a hot tub, it’s important to have components designed to deliver high fidelity sound in a wet, outdoor environment. We offer a range of integrated music options so that you can find the entertainment system that works best for you.
Aventine is a wonderful spa.
“Great small spa; very comfortable and easy to maintain. I’ve used daily for 3 years without any problems. “
Love the 2-Person Spa!!!!
It is the best overall spa we have ever owned. You cannot believe how roomy it is for the size and the features are great. Comes with lights and spots to hold drinks.
Our hot tub for two
We are very happy how easy it is to use and maintain the Aventine and we would recommend it to any one who is looking for a hot tub for two.
Aventine (Life Saver)
At 71 years young this spa is a life saver. I get in it right after I wake up each morning and it loosens up my aching muscles and joints so I can go out and shoot a money winning round of golf.
This is the second Hot Springs spa we have owned and would definitely purchase another one. We would recommend Hot Spring spas to anyone who talks about purchasing a spa.
