You may have passed a reflecting pool and seen this amazing effect: the water’s surface looks like a flat sheet of glass or appears to be perfectly contained without walls.
This effect is created by a perimeter overflow, a style used in many modern swimming pool designs in which the water overflows its edges and flows into a hidden slot or catch basin where it is then recycled back into the pool. This function is similar to an infinity-edge pool, but with a perimeter overflow, the water overflows on all four sides.
There are two main types of perimeter-overflow pools and spas: deck-level and raised. Deck-level perimeter-overflow pools are a popular style for contemporary homes. Many deck-level pools feature raised perimeter-overflow spas, which have a unique cube-like look.

Deck-Level Perimeter Overflow Pools
When the surface of the pool is flush with the deck, it creates a highly reflective surface and sleek contemporary look. The water appears motionless as it flows over all the edges simultaneously. Additional water features are not commonly included on perimeter overflow designs because the falling water would disrupt the pool’s smooth surface.
A deck-level perimeter overflow is often called “knife-edge” and “zero edge” because the slot where the water falls is almost invisible. It is also called “Lautner-edge” after Los Angeles architect John Lautner who first adopted the concept.

Dark interior finishes help to produce the mirror-like surface of the perimeter overflow. This is often used for reflecting pools as well as swimming pools.
