Caldera Spas: Built to Perform
Caldera designs every hot tub around one goal: helping you feel better. From the engineering of the shell to the precision of every jet, no detail is accidental. The FreshWater® Salt System keeps your water clean, soft, and natural-feeling for up to a full year — so your spa is always ready when you are. The result is a spa that delivers a genuinely therapeutic experience — every single soak.
Freshwater Salt SYstem
- Salt System Technology: generates chlorine naturally from salt, keeping water fresh, clear, and soft-feeling for up to a full year.
- Fewer Chemicals. More Soaking. You spend less time managing your water and more time enjoying it.
FiberCor Insulation: Superior heat retention, lower energy bill
- This full-fill insulation method keeps heat inside the spa where it belongs, reducing energy consumption and maintaining water temperature efficiently even through Michigan winters.
Hot Tub Circuit Therapy® — A Full-Body Massage, Not Just Jets
- Caldera's signature Hot Tub Circuit Therapy® is what sets these spas apart from the competition. Each seat is designed to target a specific muscle group — back, shoulders, calves, feet, hips, and neck.

Additional Features and Options
Aquarella waterfall
The Aquarella Waterfall is a built-in cascading water feature available on select Caldera Spa models. It adds a soothing visual and auditory element to your soak — the sound of flowing water creates a naturally calming atmosphere that enhances the overall hydrotherapy experience. The waterfall integrates seamlessly into the spa’s shell design and can be toggled on or off to suit your mood.
freshwater IQ
The FreshWater IQ System takes the guesswork out of water care. This intelligent saltwater monitoring system continuously tracks your spa’s sanitizer and pH levels. The result is consistently clean, clear water with minimal effort on your end, and fewer chemicals overall.
Bluetooth Audio System
Caldera’s integrated Bluetooth speaker system option lets you stream music, podcasts, or anything else directly from your phone or device to weatherproof speakers built right into the spa. The audio is tuned for outdoor use so it sounds clear even with jets running. Pair your device once and it reconnects automatically every time you’re ready to soak.

Everything You Want to Know
Most in-stock Caldera Spas at our Metro Detroit showrooms can be delivered within 1–2 weeks. Delivery includes placement at your home and a full in-home startup walkthrough so you're up and running the same day. Lead times on special orders may vary — call or visit either showroom for current availability.
Absolutely. Caldera's FiberCor® full-foam insulation is built for cold-climate performance. Many Michigan owners use their hot tub most in winter — and Caldera's energy efficiency keeps operating costs low even when temps drop below zero.
The FreshWater® Salt System continuously generates chlorine from a titanium cartridge and salt, meaning your spa self-sanitizes. You get softer water, fewer chemicals, and up to a year between complete water changes. It's standard on all Utopia Series models and highly recommended across the lineup.
Every purchase includes standard delivery ($650 value), a premium insulated cover, a watercare startup kit ($259 value), and an in-home startup tutorial. Financing is available with multiple plans including 0% interest for qualified buyers.
Yes — and we strongly encourage it. Beninati offers one of Metro Detroit's only true wet-test experiences. You get in the actual spa, feel the jets, experience the seating, and know exactly what you're buying. Book your appointment at our Utica or Clinton Township showroom.
