Comparing Hot Tubs: Which Model Is Best?

Picking the perfect spa for your home isn’t an easy decision. There are so many models and makers out there, it can be difficult to know which hot tub is best for you. Whether it’s your first time, or whether you’re an old hand at this, buying a hot tub is an exciting moment. Even finding a new replacement for an older model can be a big decision. For first-timers and seasoned spa owners alike, the first step is the same: taking a look at the market to see what’s available and comparing hot tubs.

This can be easier said than done, even for those with experience. There’s an almost limitless number of sizes, features, options, warranties, colors, and accessories available for you to choose from. Facing down this flood of information can lead to a kind of buyer’s paralysis, and shoppers risk becoming overwhelmed and delaying their purchase. So we decided to give you some of the information you need to help you make an informed decision.

Comparing Hot Tubs: Spending a quiet evening in the Hot Spring Grandee NXT


For starters, we’ve created a side-by-side comparison of two premium spa collections: the Highlife®Collection NXT from Hot Spring® Spas and the J-500™ Collection from Jacuzzi®. The Hot Spring Highlife Collection NXT is a modern luxury spa that was designed in partnership with Designworks®, a BMW Group Company. The Highlife Collection NXT spas are a stunning enhancement to any home. Designers began with the user in mind and created a beautiful, easy-to-use, energy-efficient hot tub for the home spa owner. The Jacuzzi® J-500™ Collection was designed with fiber optic ProEdge™ lighting technology, giving the spas a beautiful “glow.” Beyond its looks, the J-500™ model is energy efficient and employs user-friendly advanced technology.

By comparing hot tubs from both collections directly, you’ll be able to gain a good idea of what matters the most to you and your family as you use your spa.

To give you a sense of where each model in the two series stands in terms of size, seats, and number of jets, this first chart features a direct comparison. A few things to keep in mind: When it comes to jets, quantity and quality are not equally important. Sheer numbers matter much less than the strength and positioning of your jets. Also, when it comes to size, “bigger” might not mean “better.” It’s all about personal preference: The best size for a hot tub is the size that works best for the people who use it. For instance, if you mostly plan on using your hot tub alone or with a single partner, a roomy hot tub that can accommodate a large group might be less desirable to you than a smaller model. Keep this in mind when comparing hot tubs.
