Peoria's pools make the most sense once you know how quickly this city grew — and how much pool building changed at the very moment it did.
The modern pool took shape over decades. Gunite, the sprayed-concrete method that freed pools from rigid poured forms, arrived in the 1940s and set off a mid-century boom in freeform and kidney-shaped designs. Through the 1950s and '60s the craft matured — PVC plumbing replaced galvanized iron and copper, skimmers and main drains became standard — and by the 1980s two Arizona-defining changes landed close together: aggregate finishes like Pebble Tec, invented in neighboring Scottsdale in 1987–88, and the state's pool barrier law in mid-1991.
Here's what makes Peoria distinctive: it was still a small town of roughly 2,500 people as late as 1970, then exploded into a city of more than 200,000. According to Point2Homes, the median home in Peoria was built in 1999, with about 27% of homes going up between 2000 and 2009 and another 17% from 2010 to 2019. That means the bulk of Peoria's pools arrived right around and after those two turning points. Most were built to the modern barrier standard and finished in aggregate from the start — a genuinely different starting point than the older Valley cities.
But Peoria isn't all new. The oldest neighborhoods in south Peoria hold earlier stock that can predate both the barrier law and the aggregate era — original plaster, pre-barrier layouts — while the master-planned communities up north went in almost entirely in the modern era. So the question we ask first in Peoria is simply: north or south, and what year? That usually tells us more than anything else about what a pool needs. Whatever the answer, the water runs hard here like the rest of the Valley, so planning for scale is part of every honest conversation about a Peoria pool.
