Buying a 120v vs. 240v hot tub can be a difficult decision, especially for first-time buyers. Even for those who have purchased a hot tub before, choosing between these two types can be challenging due to the various opinions online.

Let’s take a closer look at the differences, pros, and cons of 120v and 240v hot tubs. By the end of this article, you should have a clear idea of which type suits your needs best.

120v Hot Tubs

120v hot tubs are often portable and available in various designs, including inflatable and acrylic models. These hot tubs are user-friendly and can be plugged into a standard electrical outlet.

Pros of 120v Hot Tubs

  1. Easy Installation
    No complicated setup is required. Simply plug the hot tub into an existing 120v power outlet, fill it with water, and it’s ready to use.

  2. Highly Portable
    With no permanent power connections, these hot tubs are easy to move. Inflatable models are especially convenient for relocation.

  3. Power Efficient
    These hot tubs use less power, which helps keep electricity bills low.

Cons of 120v Hot Tubs

  1. Takes More Time to Heat Water
    120v hot tubs heat water at a slower rate, typically 1–2°F per hour. This requires planning ahead for use.

  2. Smaller Size
    These hot tubs typically accommodate only 4–6 people, making them less suitable for larger gatherings or families.

  3. Expensive to Upgrade
    Converting a 120v hot tub to a 240v setup can be costly and time-consuming, requiring additional equipment like circuits, breakers, and GFCI cords.

240v Hot Tubs

240v hot tubs are designed for higher voltage and often include advanced features and performance enhancements, making them ideal for serious hot tub enthusiasts.

Pros of 240v Hot Tubs

  1. Quick Heating
    These hot tubs heat water faster and maintain temperature more efficiently than 120v models.

  2. Higher Jet Count
    With more jets and powerful performance, 240v hot tubs are excellent for hydrotherapy and massages.

  3. Simultaneous Pump and Heater Operation
    Unlike 120v hot tubs, 240v models allow the pump and heater to run at the same time, enhancing the soaking experience.

  4. Wide Range of Accessories
    Choose from features like Bluetooth speakers, underwater lights, Ozonators, and more.

Cons of 240v Hot Tubs

  1. Requires Additional Setup
    Installation requires professional assistance from a certified electrician and may involve upgrading your home’s electrical system.

  2. Difficult to Move
    Since the power supply is fixed, moving a 240v hot tub requires reinstallation of the electrical setup.

  3. Higher Installation Costs
    Materials such as wiring, GFCI outlets, and circuit boxes, along with labor costs, make 240v hot tubs more expensive to install.

Conclusion

The choice between a 120v and 240v hot tub depends on your needs, budget, and preferences:

  • 120v Hot Tub: Ideal for casual use, portability, and budget-conscious buyers. These hot tubs are easy to set up and operate but may lack advanced features.
  • 240v Hot Tub: Suitable for those who prioritize performance, quicker heating, and enhanced features. While more expensive, they provide a superior soaking experience.

If you’re a serious hot tub enthusiast, a 240v model is worth the investment. However, if you’re exploring hot tubs as a hobby or looking for a portable option, a 120v hot tub is a more affordable choice.
