Infinity Pool Cost & Feasibility in the Phoenix Metro

What a negative edge pool really costs in the Phoenix metro, which lots can support one, and the engineering that separates a true infinity edge from a perimeter overflow.

A negative edge pool is the most requested and least understood design we quote. Homeowners see the vanishing water line against a mountain view and assume it is a finish upgrade. It is not — it is a structural and hydraulic decision that changes the shell engineering, the equipment set, and in many cases whether the pool can be built on that lot at all. Key Takeaways A negative edge needs a grade change and a view to work; on a flat interior lot it reads as an expensive wall with no payoff. Expect a meaningful premium over a comparable conventional pool — the catch basin, second pump, and engineered edge wall are all additional structure. The catch basin is the hidden cost. It is effectively a second concrete vessel with its own plumbing, and it must be sized for surge, not just for flow. Edge-wall level tolerance is measured in fractions of an inch across the entire span; this is a…
