Outdoor hot tubs face more external environmental challenges, including weather changes, dust, leaves, and other natural elements. Indoor hot tubs are relatively simple to maintain because they are not subject to the effects of the outdoor environment.

Based on typical usage, the monthly energy consumption of a plug and play hot tub depends on several factors, including the size of the tub, how often it is used, the ambient temperature, and the quality of the insulation. A typical plug and play hot tub, used for about an hour per day, may add $30 to $60 to your monthly electricity bill.
