If you’re looking for a spa that comfortably accommodates friends and family, seating seven adults, the Niagara® hot tub is a crowd pleaser. Its power and size makes this hot tub model an exceptional performer and perfect for backyard entertaining.
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.
Our unique and patented design automatically generates chlorine from salt, keeping water clean and fresh up to 3x longer than any other system. After all, your spa should take care of you, not the other way around.
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.
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 Utopia® Series comes from its Avante™ all-climate cabinetry. Avante is an amazing long-strand fiber technology that is so 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 Utopia 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 Utopia® 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 Avante™ all-climate cabinet and elegant new shell design, the Utopia 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.
The SpaGlo system in our Utopia Series models includes six colors that accent individual zones throughout the spa. All the zone lighting is adjustable. We’ve enhanced the system with pin-point lighting that highlights selected areas of the spa, including the Euphoria® jets in the footwell of the Geneva®, Niagara® and Tahitian® models. In addition to their interior lighting, the Utopia Series models feature corner and perimeter lighting that intensifies the beauty of the area immediately surrounding your spa.
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.
Seat or lounge (varies by model) for neck, shoulder and middle back massage.
A contoured pillow cradles your head while specialized above-the-water-line jets focus on neck and shoulders.
Multiple jets focus on large muscles in your back. Select models work on wrists and calves.
A unique jet configuration relieves tension and pain in your back’s lumbar region.
These jets provide a deep, penetrating massage to thighs, knees, calves and feet (Two in most Utopia® models).
In Niagara, Geneva and Cantabria these jets work an often overlooked stress point and enhance movement there.
In Utopia® models they work on muscles in the lower leg.

We have had our Niagara for about one year now. It is a beautiful addition to our patio area. We spend quite a bit of time in it. Plenty of room for several people! Love it!
