What is an infinity edge pool?

An infinity edge (also called a vanishing edge or negative edge) pool uses a designed overflow where water cascades over one or more edges into a recirculation basin below the pool deck. This basin collects the water and returns it to the filtration system, allowing the pool to maintain a continuous spill without the water level dropping. The illusion created is that the pool has no visible edge and blends seamlessly into the landscape beyond.

The design typically includes a weir, a low wall that controls the water's flow over the edge, and a catch basin built into the deck structure or ground. The basin must be sized to handle the volume of water being displaced, and the pool's pump and filtration system recirculate that water back into the main pool. In Naples, where elevated views and waterfront perspectives are common, infinity edges often face toward water features, golf courses, or scenic vistas to maximize the visual effect.

Construction requires precise grading, waterproofing of the catch basin, and careful plumbing integration. The deck edge must be finished cleanly, and the system's pump capacity must match the intended flow rate. Custom luxury feature contractors in the Naples area typically handle the structural and hydraulic details of infinity pool installations.
