What’s the Difference between Voltage in Hot Tubs?

When looking at buying a hot tub, one thing you will have to consider is if you want a 110-Volt or 220-Volt hot tub. Now, the big question is, what’s the difference between voltage in hot tubs?

Each option has different benefits and features that the other does not. Both of them, however, offer luxury and complete relaxation. Let’s discuss the differences between both voltage models and the benefits they bring to the table to ensure you get the most out of your spa experience.

What Is Voltage?

Voltage is the amount of electricity traveling through an electrical current at one time. This enables electricity to reach certain devices and switches allowing for things as simple as turning on a light or heating a hot tub’s water. The voltage makes a difference in how much electricity your hot tub is receiving and what it can do with this power.

For example, the 220V hot tubs are receiving more electricity than the 110V options. With this excess of power, the 220V models can better handle certain tasks, or more tasks at once.

Now that we know the difference between these two options, let’s discuss what that difference can do for you.


110V hot tubs are commonly known as “Plug N Play” hot tubs because they can simply be plugged in to any regular outlet and receive the energy they need. With these hot tubs, all you need to do is fill them up, plug them in, and once the water is heated up, you are ready to use it.

Another great benefit to these hot tubs is they are usually smaller and lighter than the 220V hot tubs. Both homeowners and renters and love how easy it is to transport these hot tubs. When it comes time to move, you can simply pick up and take it with you.


220V hot tubs are usually larger and once they are placed, they are meant to stay. The biggest benefit that comes from 220V hot tubs is the extra power. They heat up the water faster than the 110V models, and for a lot of people, this is one of the most important features.

On top of that, the 220V hot tubs have extra capabilities. For example, 110V hot tubs can either run the jets or heat the water while 220V can do both at the same time. The 220V models also more commonly feature special additions such as: Wi Fi, extra jets, and lighting capabilities. 

Whichever model you decide is best for you and your home, something to remember is that both options are designed to keep the water warm 24/7 after it’s heated, as well as retain the heat through the hot tub’s insulation.
