Choosing a Hot Tub with the Right Voltage

articletitle featured 2marquis spa with four users

What? Hot tubs come with a choice of voltage? Most of us have no idea that voltage is actually one of the decisions that need to be made when purchasing a hot tub. We get mired down in the myriad of other fun choices we need to make: seating configurations, number of jets, LED lighting options, and whether we should go with the Bluetooth stereo. The issue of voltage never crosses our minds. Well, it turns out that your choice of voltage could be significant. So, how do you go about choosing a hot tub with the right voltage for your needs? Never fear, we are here to provide you the information.

The Two Choices

Hot tubs come in two voltage options: 110 and 220. In the past, most hot tubs were manufactured to run on 220V, and for the larger sizes of spas, that is still a good choice. These days, however, some spas can come in a 110V. So why choose one over the other?


A 220V hot tub will heat up more quickly and maintain its temperature longer, even in colder temperatures. If you plan to use your hot tub in the winter, the higher voltage will be your friend. Spas that run on 220V can run the heater and jets at the same time and keep the temperature where you want it for as long as you like. If you live in a mild climate and won’t be using your hot tub for hours on end, the 110V may suffice. Keep in mind that with the lower voltage, your hot tub will take longer to heat up.

Capacity and Jets

Do you want a big hot tub with a lot of jets? Then the 220 voltage choice is for you particularly if you plan to have 4-6 people in the spa at a time. If you will be using the hot tub by yourself or with one other person, the 110 voltage might be just fine. Another consideration is that the 220V hot tubs can run multiple features at one time such as heater, jets, special lighting, and built-in sound systems. The 110V hot tubs can struggle to run multiple features at one time and also may have inconsistent jet pressure.


The 110V hot tubs are called “Plug-N-Play” for a reason. All you have to do is plug them into a normal electrical outlet, let them heat up, get in, and enjoy a nice long soak. A 220V hot tub requires a 220 outlet, which you may need an electrician to install. The 220 outlet will be connected to your home’s central circuit breaker box This could add to the cost of the initial price of your spa by as much as $1000. 

So, which to choose? The choice is ultimately a matter of your personal preference and needs. If you live in a colder climate and/or want a larger hot tub to accommodate more people and special features, the 220V will be for you. Keep in mind you may need an electrician to get you set up properly. On the other hand, having a Plug-N-Play hot tub makes temporary installation much easier. Choosing a hot tub with the right voltage is something you will have to consider when making your purchase, but with the right information at hand, we are confident you will make the right choice
