Hot Tub Electricity Cost Calculator
Truth to tell, there is no straightforward answer to it. The electricity cost mainly depends on 5 main factors.
1. Size Of Tub
The size of your tub can be a deciding factor. Keeping the water warm will use more energy. And using more energy will add up to your monthly bills. Before you choose the tub, consider the following things:
- How Many People Are Going To Use It

Draining the tub could be a difficult task. So, keep in mind that bigger is not always better.
2. How Often You Use It
