Caldera Spas® Utopia® Series vs. Marquis Spas® Signature® Series

A hot tub helps complete a home, providing its owner with year-round luxury, comfort and health benefits. When considering any luxury hot tub, you’ll want to do your research so that you purchase a durable and reliable spa that offers all of the systems, features, and options you desire. Whether you’re a first-time spa buyer or trading up to a new hot tub, research will help you build the confidence you need to find the spa that’s perfect for you and your family.

To get you started, we’ve compared two luxury spa series side by side—the Utopia® Series by Caldera Spas® and the Signature® Series by Marquis Spas®.

The Caldera Spas® Utopia® Series vs. the Marquis Spas® Signature® Series

The styling of the two series is very different. The Utopia® Series embraces modernity in its material and technology, including in its entertainment options and LED spa lighting. Marquis Spas® has taken a different route, using modern features such as LED lighting in a more subdued way.

Caldera Spas® Utopia® Series

The Utopia® Series by Caldera Spas® features the distinctly modern Avante® all-climate cabinetry designed to evoke the sensation of movement. Its long-fiber technology resists not only the elements, but also cracking, splitting, and chipping. The exterior corner LED lights further the distinctly modern air and provide visibility to the deck or patio area around the spa.

Marquis Spas® Signature® Series

The Marquis Spas®Signature® Series uses DuraWood™ cabinetry in a very traditional design. It is resistant to rot in a way that wood cannot match, yet it looks very much like woodwork. LED lighting is present below the waterline of the spa and on the exterior of the cabinet.

Marquis spas® and Caldera spas® offer distinctly different systems and features.

Comparing the Caldera Spas® Utopia® Series to the Marquis Spas® Signature® Series

Both the Utopia and Signature® series offer high-quality, luxury models. So, it’s helpful to review the primary factors that distinguish them—spa size, seating, and the total number of jets.

When it comes to spa size and jets, the two series are comparable. With regard to seating, the Signature® Series offers two- and three-seat models, while the Utopia® Series includes an eight-seat hot tub for which the Signature® Series has no answer.

Choosing the Ultimate Home Hot Tub

A hot tub is more than the sum of its parts; how you plan on using it will also figure greatly in your final decision. Because no two spa collections are exactly alike, you’ll need to judge them on the most important criteria—performance, comfort, and design.

  • Reliable Performance. You’ll want a hot tub that provides forceful jets for hydrotherapy and gentler settings for more relaxing soaks. Since the best hot tub is one that is used every day, you’ll want performance paired with masterful engineering.
  • Comfort. The best hot tub for you enhances the spa experience with special features and precise control over them. Stimulating hydrotherapy massage should give way to soothing bubbles with minimal fiddling.
  • Superb Design. You deserve a hot tub that exhibits the great care put into its manufacturing and design. A spa should be beautiful, flawless, and good match for your home, while at the same time providing the comforts of modern technology and engineering.
Your perfect hot tub should provide years of relaxation.

Narrowing Down Your Hot Tub Choices

When offered, a test soak at your local spa dealer will allow you to experience jet performance, work the controls, and more, so you can take home the spa that best suits your needs.
