An infinity pool, also known as a vanishing edge pool, is a type of swimming pool with one or more edges that appear to end at the horizon. The pool design typically involves creating the illusion that the water spills over the edge, blending the pool into the surrounding landscape. This design requires careful planning and engineering to ensure structural integrity and safety. A '46 floor infinity pool plan' would refer to a blueprint or layout for an infinity pool located on the 46th floor of a building, which would present unique challenges such as supporting the structure at high altitudes and ensuring the pool's appearance is seamless with the skyline.
