Illustration of transparent infinity pool

Quick answer：

An infinity pool, also known as a vanishing edge pool, is a design feature where the pool appears to have no edge as it extends into the landscape beyond. This effect is achieved by having the pool's edge at the same level as the ground, creating the illusion that the water spills over the edge into a larger body of water. Transparent infinity pools are constructed with glass or clear materials, allowing a seamless view of the water's depth and the surrounding environment. These pools are often installed in luxurious homes and hotels for aesthetic appeal and a sense of openness.
