110v vs 220v Hot Tub – Comparison Guide


Buying a hot tub means making a lot of choices. One of the largest decisions refers to voltage. Choosing whether to get a 110V vs 220V hot tub can be a bit overwhelming, so it is important to know the difference between them. 

110V hot tubs can typically be plugged into a standard outlet. On the other hand, 220V hot tubs are connected from the main circuit box to the spa by using a safety box. Since both kinds of tubs have their pros and cons, we will talk about getting a 220V vs 110V hot tub in detail so you can choose the best one. 

110V vs 220V Hot Tub Comparison 

110V Hot Tubs

  • Lower Cost. 110V hot tubs are also called ‘Plug and Play’. Their price is lower than the price of 220V tubs. That’s why they are more commonly bought by spa builders and those who do not want to splurge on a spa. They cost less because they are smaller and have fewer jets. Also, they come with less powerful heaters and pumps. Overall, these kinds of hot tubs have less ‘attractive’ features. 
  • Easier Installation. These hot tubs are much easier to install. Simply place it in a suitable location, fill it with water and turn it on. Just make sure the place can support its weight, and you are all set. It does not get much simpler than that. You can plug in 110V into most outlets. But, you may need to plug it into a 20 amp outlet or unplug other loads on the required circuit.
  •  More Portability. 110V hot tubs often weigh less than 220V hot tubs because they are smaller and have fewer features. For example, inflatable hot tubs and rotomolded hot tubs are a perfect example of portability. However, some models’ weight can be up to 500 lbs. 

220V Hot Tubs

  • Larger Tubs. When you are comparing a 220V vs 110V hot tub, you may notice that 220V tubs are typically larger. So, if you want a tub that can fit 5 or 6 people, maybe it is better to get a 220V one. A larger tub with larger filters is much easier to maintain than a small tub. 2-people hot tubs can overflow if more people try to fit there.
  • Larger Heaters. Larger tubs generally require larger heaters. When comparing a 110V vs 220V hot tub, it is obvious that smaller heaters can take longer to heat and reheat the tub. If a spa is not well-insulated, or if the cover is off, it will lose the heat much quicker. This is very important if you want to be able to relax in your tub at any time. 220V tubs can heat the water no matter if the jets are turned on low or high. On the other hand, 110V tubs can heat it only when the jets are running on low power. 
  • Larger Pumps. 220V tubs often have 4 to five horsepower pumps, which means they are much more powerful than 110V tub pumps. Less powerful tubs cannot manage both the pump and the heater at the same time so if you want more power, it is a better idea to go with 220V tubs. Larger pumps will make the whole experience much more comfortable. 

Convertible Hot Tubs

If you are not able to choose the best option in the 220V vs 110V debate, it might be a good idea to get a hot tub with a convertible voltage option. Such tubs can work using either voltage which is a very convenient feature. 

The heaters will switch to a smaller power if you run the tub on 110V. Besides, the tub will make other smaller adjustments to distribute the power accordingly. For example, it will opt for low-speed pumping while the heater is running. 



Q: What’s Better 110V or 220V Hot Tub?


110V hot tubs generally cost less, are easier to install, and are more portable so they are better if you have a smaller budget. On the other hand, 220V hot tubs are larger with bigger pumps and heaters so they are better if you want to invest in a tub that can fit more than 3 people.

Q: Is 110V Better Than 220V?


The answer depends on your preference. If you’d like a smaller hot tub which costs less and is easier to install, then 110V tubs are better than 220V ones.

Q: What Voltage Do You Need for a Hot Tub?


A hot tub generally needs 110V or 220V voltage. The type you choose depends on your preference and needs.

Q: Do Hot Tubs Need 220V?


Not all tubs need 220V. You can also get 110V hot tubs but they are generally smaller and less powerful.

Q: Will a 220V Motor Run on 110V?

A: It is technically possible to run a 220V motor on 110V but it is not recommended because the motor will certainly die because if it was not specifically made for this voltage.

Q: What is the Difference Between 220V and 110V?


220V hot tubs need more power to run smoothly and safely because they are larger and have bigger pumps. On the other hand, 110V hot tubs require less power because they are smaller, more portable, and easier to install.
