Each hot tub owner will have different operating costs depending on the model purchased, the temperature set, frequency of use and the outside temperature.
It depends on your hot tub. All hot tubs use a different amount of power. It will depend on the cost of electricity in your area and how you plan to use your spa. Your dealer can walk you through those estimates.
The cost to operate an energy efficient hot tub is only $10 to $20 per month. Outdoor hot tubs in colder climates may cost more to run.
