Welcome to our forum.
The first month is always much higher than subsequent months. 8-)
There are so many factors.What is the cost of your electricity? Â What temp do you keep the tub at? Â How often is it used? Â Jets on? Â Jets off? Â Bubbler? Â 60 amp? Â 50 amp?$60/month could easily be at the high end of normal for a Sundance.
I am curious why do you say normal for a Sundance and also would not the model play a big part. The Maxus would be the only model I would think they make that could run that much but that is a much larger tub than most others.
