What Makes the Paradise Series Different?
Paradise blends practical and premium. Every model is ready for FreshWater® IQ, which adds hourly water testing and one-touch dosing to salt-water care. EnergyPro® circulation and FiberCor® insulation keep running costs low through the year.
Hot Tub Circuit Therapy®
Caldera builds each seat as its own station, with a different jet layout aimed at a specific muscle group. You move from seat to seat and work through a full-body circuit, the way you would a set of exercises.
Made for the evening
SpaGlo® multi-zone lighting sets the mood inside and out, and an Acquarella® illuminated waterfall adds the sound of moving water. The EcoTech® cabinet keeps the outside low-maintenance and contemporary.
Efficient to run all winter
The EnergyPro® circulation pump runs on low wattage and returns most of its energy to the water as heat. FiberCor® insulation with a WeatherPro® cover holds that heat on cold Tennessee nights, so your running costs stay low when you use it most.

Get PricingFind the Right Hot Tub
Most people only buy a hot tub once, so it’s normal not to know where to start. These six questions cover what actually matters. Answer them and you’ll know what to look for.
How many people will use it?
Choose based on a normal week. This one answer narrows the field more than any other.
What do you want it to help with?
Back pain, arthritis, stress relief, better sleep. Each one has a straight, sourced answer in Hydrotherapy 101.
Lounge seat, or open seating?
A lounge lets one person recline full-length. Open seating fits more people. Neither is better, and it’s the main reason to try a few spas before choosing.
Which features matter most?
Massage systems, water care, lighting, audio, smart controls. Don’t get hung up on jet count, though; where the jets sit and how they’re designed matters far more than how many there are.
Do you want salt water care?
Softer-feeling water, far less dosing, and up to a year between water changes. Paradise is salt-ready, so you can add the FreshWater® Salt System whenever you want it.
What’s your timeframe?

Salt-ready water care with FreshWater®
Every Paradise spa is salt-ready, so you can add the FreshWater® Salt System whenever you want it. It turns a small amount of dissolved salt into chlorine automatically, so you spend far less time on upkeep and add fewer chemicals.
How the Salt System works
A titanium cartridge converts dissolved salt into chlorine as the water circulates, and it’s owner-replaceable about every four months. Softer-feeling water, less dosing, and up to a year between water changes. Learn more about the Salt System.
Add FreshWater® IQ for hands-off testing
Every Paradise model is FreshWater IQ ready, so you can add hourly water testing and one-touch dosing on top of the salt system. The spa tests itself, shows what it needs on the panel or app, and corrects pH at a tap. Learn more about FreshWater IQ.

Frequently Asked Questions
Quick answers to the hot tub questions we hear most. The Learning Center covers each one in depth.
How much does a Paradise hot tub cost?
Paradise is Caldera’s premium series, so it sits in the upper part of the Caldera range. Our cost guide walks the tiers with real numbers. We don’t price a specific model sight-unseen because your real cost depends on the model, the features you choose, and what your site needs. Get pricing and we’ll quote your exact setup, no pressure and no obligation.
Will it cost a fortune to heat in winter?
Cold climates cost more, but Paradise is built for it. The EnergyPro® circulation pump returns most of its energy to the water as heat, and FiberCor® insulation with a WeatherPro® cover holds it in. The cover is the biggest daily factor.
Is the salt system included?
Paradise is salt-ready: the FreshWater® Salt System is an option you can add rather than standard equipment. Every model is FreshWater® IQ ready, so you can add hands-off testing and dosing as well.
What size Paradise do I need?
The series runs from the three-seat Kauai® up to the seven-seat Salina® and Reunion®, with lounge and open-seating layouts in between. 2 to 3 seats fits couples and small spaces, 4 to 6 fits most families, and 7 is built for entertaining. If you’re between two sizes, choose based on a normal week.
