Infinity Pool vs Overflow Pool: What's the Difference?

Infinity pools and overflow pools are two of the most visually stunning pool designs available. Both create a "vanishing edge" effect where the water appears to flow endlessly into the horizon, but they work quite differently. Here's everything you need to know.

What is an Infinity Pool?

An infinity pool (also called a negative edge or vanishing edge pool) has one or more edges where the water flows over the rim into a catch basin below. From the swimmer's perspective, the pool appears to merge seamlessly with the landscape, sky, or ocean beyond it. The water is collected and pumped back into the main pool continuously.

What is an Overflow Pool?

An overflow pool (also called a wet deck or rim-flow pool) has water that rises to exactly the level of the surrounding deck and overflows on all four sides into a perimeter gutter or channel. This creates a mirror-like, perfectly flush surface — popular in luxury resorts and high-end residences.

Which is Better for Tamil Nadu and Kerala?

Infinity pools are the more popular choice in Tamil Nadu and Kerala because many luxury villas and farmhouses are built on sloped terrain — perfect for the vanishing edge effect. In hill areas like Ooty, Kodaikanal, and Wayanad, infinity pools create breathtaking views.

Overflow pools are preferred for high-end resorts and properties with flat terrain where a mirror-like aesthetic is desired. They are commonly seen in luxury resorts in Kerala's backwaters and Coimbatore's premium residential projects.
