110v vs. 220v hot tub

6 Minute Read

Hot tub shopping is full of choices and decision-making. There are many factors to consider when narrowing down your choices. While size, jet configuration, seating options, water care, filtration, and features for ambiance such as lighting, sound systems and waterfalls are all things you’ve probably already considered, have you thought about the voltage of your future hot tub? This article will explain what 110v and 220v mean, the difference between them, what type of hook up either requires and more. In addition, Larry Ovalle, Jacuzzi VP of Innovation and Technology, offers his expert insight and recommendation on which is better — 110v vs 220v hot tubs.


What does a 110v or 220v mean?

Beginning with the basics, the “v” in a 110v or 220v hot tub refers to the voltage of the electrical line from the main electrical panel of a home. In North America, a 110/120v is a standard wall outlet. A 220/240v is a dedicated electrical line that is typically run to a hot tub. Understanding the basics of this can help you pick out a hot tub with the appropriate voltage setup.


Which type of voltage does a Jacuzzi® hot tub require?

If you are considering a Jacuzzi® hot tub, you will typically need a dedicated electrical hookup that is 22v or 240v. We also suggest a 40, 50 or 60 amp breaker be installed in order to use all the pumps and heaters at the same time. A breaker refers to a circuit breaker, which is an electrical safety device that serves to automatically stop the flow of power. This helps protect your hot tub (or any equipment connected to it) as well as your house from fire risk in the case of a short circuit or overcurrent. The number associated with the amp refers to the maximum amperage, which translates to Watts that can be transferred to the equipment on the circuit. It’s also important to understand that any given circuit breaker is designed to handle approximately 80 percent of its overall amperage.


Which is the best option — 110v vs 220v?

A 220v/240v is the ideal option so you can use all the features of your hot tub at the same time. This setup will allow you to have the best hydrotherapy experience without having to worry about tripping your circuit breaker. A 110v hot tub typically uses weaker heaters and pumps, so the hydrotherapy experience will not be as good as if you were in a 220v hot tub. However, these systems tend to be easier to install without requiring any updates to your home’s electrical system so you will want to weigh the pros and cons. While these systems may consume less power, a 220v/240v system is very efficient without adding a significant amount to your electric bill. Plus, you get the added benefit of enjoying all the hydrotherapy features of your hot tub at one time. When you’re looking for a 220v hot tub, you’ll want to look for these five features every quality hot tub should have.

110v vs 220

Do 110v or 220v hot tubs require professional installation or hookup?

A 110/120v hot tub does not require the assistance of an electrician if there is an outdoor wall outlet available to plug the spa in. However, if an outlet is needed or the one available isn’t sufficient to handle the voltage, the help of an electrician may be required, regardless of the amperage of the hot tub you choose. An electrician is necessary for the hookup of all 220/240v systems. It’s important to note the experts at Jacuzzi always recommend the expertise of an electrician in case you have any questions, concerns or issues. This is where the term “plug and play” hot tub comes from. These types of hot tubs are meant to be able to simply “plug in” and enjoy them soon after installation.


In short, a 220/240v hot tub model with a 50 or 60 amp breaker electrical is the recommended choice so that all the pumps and heaters can run uninterrupted. Even a 220v/240v hot tub with a 40 amp breaker cannot run the jet pumps and the heater at the same time. So, for example, if you live in a cold climate or are using your hot tub in the winter and the jet pumps are on, the heater may be unable to turn on so your water will cool down. On the other hand, 110v/120v hot tub models are weaker in hydrotherapy and take much longer to heat up. For example, when a hot tub is filled with water from a hose, the water is typically cold. A 220/240v model will heat the water up two to five degrees per hour while a 110v/120v system could take up to 24 hours or more to heat the water to your desired temperature, depending on the size of your hot tub.


One of the benefits of a “plug and play” hot tub is the electrical hookup is the only requirement. Most plug and play hot tubs are entirely self-contained. They are not powered by natural gas, only electric. Another plus is that plug and play portable hot tubs are equipped with their plumbing system. No additional plumbing is needed, making installation of your new hot tub hassle-free.


Once you’ve decided on the appropriate voltage you want for your hot tub, there are many other factors to consider. Here are some additional hot tub features that can enhance your hydrotherapy experience:


  • Multiple specialty jet configurations designed for full-body hydromassage
  • Smart technology that allows you to control and monitor your hot tub, even when you’re away from home
  • Softly filtered LED lighting that is easy on the eyes
  • Seating options that suit your needs including lounge seats, therapy seats, loveseats and “cool down” seats
  • Ease of entry to comfortably get in and out of the hot tub
