Infinity Edge vs. Knife-Edge Pools: What’s the Difference?

What’s the difference between an infinity edge and a knife-edge pool

If you’ve ever found yourself mesmerized by a pool that seems to spill endlessly into the sky or one that looks more like a serene mirror than a swimming space, you’ve already seen the magic of infinity edge and knife-edge pools. These two luxury pool styles are becoming favorites for homeowners, designers, and architects who want that “wow” factor – but they’re definitely not the same thing.

So, what’s the difference between them? And which one makes the most sense for your home and the way you live? We’ll break it down in a way that’s easy to follow. However, if you’re still on the fence afterward, no stress. Professional pool contractors in Prairieville can walk you through your options and help you make the call.

What’s the difference between an infinity edge and a knife-edge pool?

An infinity edge pool is designed to make water look like it’s disappearing into the horizon. The effect is created by lowering one or more walls of the pool just enough for water to flow over them continuously. That water then cascades into a hidden basin below, where it’s filtered and recirculated back into the pool. From the right vantage point, the edge simply disappears, offering a breathtaking, resort-style experience right in your backyard.

On the other hand, a knife-edge pool allows water to overflow evenly on all sides into a concealed trough. This setup creates a mirror-like finish that looks incredibly calm and symmetrical, often reflecting the sky, surrounding greenery, or nearby structures like glass. The result is minimalist and modern – perfect for homeowners who value understated elegance and cutting-edge design.

So, what’s the difference? 

While both pool styles are undeniably luxurious, they achieve their visual magic in very different ways. Here’s the simplest way to think about it:

  • Infinity edge: Designed to create the illusion of no edge—usually just on one side—for a breathtaking, horizon-melding effect.
  • Knife-edge: Designed for uniform overflow on all sides, giving it a modern, still-water appearance with clean architectural lines.

Which pool type is easier to maintain: knife-edge or infinity edge?

If we’re talking about day-to-day upkeep, infinity edge pools are generally the easier option. They use a single spillover wall, meaning fewer components and less complexity.

Knife-edge pools, on the other hand, require precise leveling during construction to ensure even water flow on all sides. Their full-perimeter troughs can be more prone to clogging and demand more attention to water balance, filtration, and cleaning systems.

What is the better option?

At the end of the day, there’s no wrong choice here. Infinity edge and knife-edge pools each have their own charm, and both can completely transform the feel of a backyard. It really depends on what suits your space and your taste. Whether you’re after bold and dramatic or sleek and understated, either option is a solid choice for a standout, high-end pool.

That said, both pool types fall under the luxury category—so either way, expect to work with experienced pool professionals and invest in quality equipment
