110v vs 220v Hot Tub – Comparison Guide

110v_vs_220v_Hot_Tub_-_Comparisson_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 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.
