When a client asks what is the on-going operating cost of a private pool, I struggle to offer a precise answer. The upfront cost to install a private pool can be determined after a 30 minute consultation with one of the many pool builders in the Phoenix area. But what are the daily operating costs that a homeowner can expect? For luxury homes, a well appointed private pool can be a standard expectation. A family with children may look to a private backyard pool as a essential activity for the children during the 100+ degree summer days common to Phoenix. So what is the day to day cost of this hydrated desert amenity?
