Comparing the Caldera Paradise Series and the Bullfrog® R Series

The Caldera Spas Paradise Series

Caldera, a leader in hot tubs, puts comfort above all else, with spacious interiors, deep seats, and the Foot Ridge™ to keep you in place so you can enjoy your soak without floating out of your seat. Jet diverter controls are conveniently located on the bar top, allowing you to customize your hydrotherapy massage without getting out of the spa. The combination of FiberCor® insulation, durable and beautiful EcoTech™ cabinets, and multiple water care options makes the Paradise Series enjoyable and reliable.

The Bullfrog® Series

Bullfrog® Spas is recognized as the creator of the JetPak Therapy System, which allows you to enjoy hydrotherapy by manually switching out the JetPaks. The premium models in the R Series allow owner customization and fit into budgets without sacrificing features. Designs place a heavy emphasis on reliability, with wood-free cabinets for year-round durability and dual-filter water care systems to keep spas dependably clear.

Consider the different design philosophies behind the Caldera Paradise Series and the Bullfrog® R Series.

The Caldera Paradise® Series vs. Bullfrog® R Series

Caldera and Bullfrog® are both known for exciting innovations in home spas. Caldera hot tubs are known for their performance, Pure Comfort® design, and Hot Tub Circuit Therapy®, which provides a deep massage to different muscle groups as you move from seat to seat in the spa. Caldera also offers a unique and optional hot tub cooling system called CoolZone™, which can lower the temperature of spa water to a cool 60 degrees Fahrenheit for summer enjoyment, and heat it back up again in just a couple of hours.

Bullfrog® is known for its JetPak Therapy System™. JetPaks can be swapped between seats even when the spa is running. But switching JetPaks to achieve the type of massage you want means getting out of the spa each time and keeping JetPaks in storage. Also remember that when it comes to jets, more isn’t necessarily better. Powerful, integrated jets that are optimized through a continuous circulation pump offer greater force and more benefits than systems that require owners to manually switch out jets. Caldera Spas offers other features, including deep seats and the Foot Ridgethat allow users to anchor themselves to get the full benefits of powerful hydrotherapy jets.

Choosing between series with very different jet technologies isn’t easy. But by comparing the quality and design of materials, equipment, and the features in each series, you’ll be one step closer to determining which spa best suits your lifestyle.
