110v versus 230v Hot Tubs

You are so excited! You’ve decided to get a hot tub for your backyard, and you just can’t wait to get started. We can’t blame you — you have made a fantastic decision. But before you buy that hot tub you have always wanted, check the voltage. Your hot tub’s voltage can make a big difference. For example, 110v versus 230v hot tubs differ in the amount of power they offer, the needed set up, and portability as well as the price. If you are trying to figure out which one you were wanting for your home, check out our breakdown of the two types of hot tubs.

110v Hot Tubs

When you see a small to medium-sized hot tub without any extra lights or features, odds are it has 110 voltage. The 110v hot tubs are great for small groups or individual soaks. They can offer the relaxation you need.

On the other hand, maybe you are looking for a bigger tub that can accommodate more people. If you don’t need one for larger groups, maybe you just want one that offers extra features like a waterfall, pressure jets, or ambient lighting. With features like these, maybe the 110v isn’t your best option. Since it’s a smaller voltage, it can’t power as many things at the same time. You might be able to have your jets running full power as long as your waterfall and lights are off. Come nighttime, you may need to shut off those jets so you can enjoy the comforting lights.

  • Lower Jet Pressure
  • Cannot Power Multiple Features At Once

230v Hot Tubs

If you are wondering if 230v hot tubs offer double the power and electricity of a 110v hot tub, you would be right. When it comes to 110v versus 230v hot tubs, you get more power, accessories, and heating with the 230v. The biggest reason people choose the 230v over the 110v is because it offers faster and more effective heating. Since there is more power behind it, the heaters work faster and heat the water quickly. As well, they can more efficiently keep your water at the temperature you want it.

On the other hand, with great power comes great benefits. You’ll be able to enjoy every amenity of your spa, including powerful jets, water features, lighting and more. Your monthly electricity bill to be a little bit higher, because your hot tub is using more energy. But the perks will outweigh the cost. Since your 230v hot tub requires more energy, it also might require additional wiring or a specific outlet to connect to. So now you have to decide what you want to use your hot tub for. Do you want it just for you and your relaxation or are you wanting something to entertain more people and offer extra functions?
