You might see an infinity pool referred to by other names. Sometimes they are called an infinite edge, vanishing edge, or negative edge pools. But they all refer to the same concept.

Basically, these are still pools without any swim current. The primary difference is that one wall is clear and slightly shorter than the others. This allows water to flow over that wall, or weir, and into a reservoir. The result is an unmistakable effect that gives infinity pools their distinct appearance.

There are many types of pools you've probably seen countless times. Hot tubs and other whirlpools offer an incredible sensory experience. Pools with a current allow for endless swimming cycles. And ordinary swimming pools are great for fun and entertaining.
