Infinity pool design guide: how to make an edge vanish into the horizon

An infinity pool is more than an overflow edge. Here are the engineering and design rules behind the illusion.

Infinity pool design guide: how to make an edge vanish into the horizon

The infinity — or vanishing-edge — pool is one of the most striking designs, and one of the most demanding to engineer. Its beauty lives in details you never see.

When does an infinity pool make sense?

It shines when the pool faces an open view: sea, lake, city skyline or golf course. Surrounded by nearby walls, it won’t deliver the effect.

Key engineering elements

The overflow wall

The edge must be perfectly level along its entire length; even a tiny difference shows up as an uneven waterfall.

Catch basin and balancing tank

Water falls into a basin below the edge and is pumped back into the pool. Its volume must be calculated carefully so it neither overflows when swimmers enter nor runs dry through evaporation.

Design considerations

  • Match the finish to the view: deep blue for the sea, grey for a city skyline.
  • Orient the edge around the main viewing angle.
  • Linear lighting beneath the edge creates a magical night scene.

Cost and upkeep

Infinity pools cost more than traditional ones because of the structure, extra basin and pumps, and they need automatic level control and regular attention to the edge. Built well, though, the pool becomes a work of art that adds real value to the property.
