Hot Tub vs Jacuzzi (What’s the Difference?)

Hot tubs and Jacuzzis. When you hear about these, you probably think they are the same thing: a tub with jets full of hot water. Although it’s common for most people to interchange these two, they are in fact different. Another common mistake people make is believing that a hot tub is the same as a swim spa.

At Modtub, we’re the experts and we’re here to break old habits. We want to explain why these aren’t all the same. So keep reading, and we’ll tell you about a hot tub vs. a Jacuzzi and a hot tub vs. a swim spa. 

For so long, society has used the term “jacuzzi” when they are actually referring to a hot tub. So, what’s the difference? A hot tub is a large tub of heated water with jets used for relaxation and recreation. On the other hand, a Jacuzzi is a trademarked brand name for jetted tubs and other spa equipment.

Last but not least, a swim spa is different from a hot tub for two main reasons: the size and the uses. Modtub is DFW’s modern hot tub company, and we provide a stress-free process to buy your next relaxing hot tub. Not only do we sell hot tubs, but we also offer fully-loaded swim spas. 

Jacuzzi Hot Tubs

Jacuzzi is a trademarked brand that derived from the Jacuzzi family, who came to the United States from Italy in the early 1900s. In the 1940s, Candido Jacuzzi invented a hydrotherapy pump to relieve his son’s arthritis. This soon led to a home version of the pump that evolved any ordinary bathtub into a relaxing hydrotherapeutic spa. The pump was known as the J-300, and its demand was great. Soon after, in the 1950s, the Jacuzzi brand was born. 

Jacuzzi became a genericized trademark or proprietary eponym, which means it has become the generic term for hot tubs. This has happened to other brands, like Kleenex – for example. Jacuzzi sells various products ranging from hot tubs to showers. Jacuzzi hot tub prices differ from other hot tubs. What does a hot tub vs. a Jacuzzi cost? Hot tub costs range from $6,000 to $16,000 or more, while Jacuzzi costs are between $8,000 and $25,000. 

What is a Hot Tub?

A hot tub is just as it sounds. It’s a tub filled with hot water that people use for relaxation, recreation, or hydrotherapy. The idea of hot tubs began in the 1960s as a wooden spa. In the 1970s, the hot tub industry was born, and hot tubs quickly advanced into what they are today. Hot tubs have evolved significantly, and now come in many different shapes, sizes, and colors and have various features. They range from very basic to fully loaded. 

You’ve probably seen a hot tub in someone’s backyard, a hotel, or maybe an apartment complex. Hot tubs are a great addition to a backyard. They add just the perfect touch to create your backyard oasis. Think about it; you can come home from a long day at work and enjoy a relaxing soak in your hot tub. Everyone knows about the entertainment and relaxation benefits of hot tubs, but they are also now widely known for their medical benefits:

  • Stress relief 
  • Improved sleep
  • Better cardiovascular health
  • Muscle relaxation 
  • Pain relief 

Hot tubs have come along way and now offer various hydrotherapy jets and settings, massagers, and even ergonomic seating. 

What is a Swim Spa?

A swim spa often gets thrown into the mix of hot tubs and Jacuzzi’s, but there is also a big difference between a swim spa vs. a hot tub. For starters, swim spas are much larger than hot tubs, sometimes double or triple the size. That’s because while swim spas have seating, they are best used for recreation and exercise. This is a key difference because hot tubs are known for relaxing and socializing. 

Swim spas and hot tubs have many of the same features, including user-friendly hydrotherapy jets, seating, lighting, user-friendly control systems, and Bluetooth capabilities. The large tank size and the powered jets set the swim spa apart. Think of it like this: swim spas are all-in-one above-ground pools, hot tubs, and exercise swim spas! The best part is, Modtub offers both hot tubs and swim spas, so you don’t have to look far for your family’s next spa.

Hot Tub vs. Jacuzzi vs. Swim Spa: The Breakdown

Hot tubs, Jacuzzi, and swim spas are commonly interchanged, all referring to a traditional hot tub. We now know that these are all different. Hot tubs are tubs of warm water with hydrotherapy jets, and Jacuzzi is a trademarked brand name hot tub.

Jacuzzi offers hot tubs and other products such as showers and bathtubs. Another common mistake is that hot tubs and swim spas are the same things when, in fact, they are very different. Swim spas are much larger than hot tubs and have other uses. While hot tubs are commonly used for winding down and relaxing, swim spas are better for exercising and entertainment because of their size.
