An infinity edge pool (also named negative edge, zero edge, infinity pool, disappearing edge, or vanishing edge pool) is a reflecting or swimming pool where the water flows over one or more edges, producing a visual effect of water with no boundary. Such pools are often designed such that the edge appears to merge with a larger body of water such as the ocean, or with the sky. They are often seen at exotic resorts and exclusive estates, in advertisements, and in other luxurious places.[1][2][3]


The infinity pool design concept is said to have originated in France, where one of the first vanishing edge designs was utilized in the "Stag Fountain" at the Palace of Versailles in the early 1400s.[citation needed]

Infinity pools are very expensive and require extensive structural, mechanical, and architectural detailing. Since they are often built in precarious locations, sound structural engineering is paramount. The high costs of these pools are often found in the foundation systems that anchor them to hillsides.

The "infinite" edge of the pool terminates at a weir that is 116 to 14 inch (1.6 to 6.4 mm) lower than the required pool water level. A trough or catch basin is constructed below the weir. The water spills into the catch basin, from where it is pumped back into the pool.
