Perimeter Overflow (Knife-Edge)
A pool design where the water spills over all four edges into a perimeter slot, creating a mirror-flat surface.
Perimeter-overflow pools are the most demanding pool design and the most striking. Water is in constant motion over every edge, requiring oversized plumbing, a balance tank, and millimeter-level shell precision. Construction cost often runs 60–120% over a standard pool of the same size.
