Few sights in luxury living compare to a perfectly still sheet of water dissolving into the horizon.
That’s the magic of an infinity edge (also called a vanishing edge or mirror pool) where architecture, engineering, and artistry meet to create a seamless visual illusion.
At Southern Pool Designs, we specialize in these technically demanding, visually breathtaking designs. Pools that don’t just complement a property, but define it.
What Is an Infinity Edge Pool?
An infinity edge pool uses a carefully calculated overflow system that allows water to spill over one or more edges into a hidden trough or “catch basin.”
The result is a reflective, mirror-like surface where the water appears to extend endlessly. Often blending perfectly with a lake, golf course, or skyline view.
It’s one of the most visually striking features in modern pool design, but it’s also one of the most technically complex to execute properly.
The Engineering Behind the Illusion
Infinity pools are less about magic and more about math.
A flawless edge requires perfect alignment between:
- Elevation and slope — even a 1/8-inch variance can break the illusion
- Hydraulic design — flow rate must balance to maintain a uniform sheet of water
- Catch basin capacity — sized precisely to handle surge volume during use
- Structural reinforcement — accounting for water weight and soil conditions on sloped lots
At Southern Pool Designs, every vanishing edge project starts with detailed CAD drawings and structural engineering to ensure visual perfection and long-term durability.
Our laser-leveling and precision-forming process guarantee a mirror-straight spillway that performs flawlessly year after year.
Why They Work Best on Elevated Sites
Infinity edges perform best when the pool is positioned above grade where the water can visually merge with a backdrop such as a lake, forest, or sunset.
For homeowners building on hillsides, elevated lots, or lakefront properties, it’s the ultimate way to frame a view.
The more dramatic the elevation change, the more powerful the effect.
If you’re working with an architect or builder, bringing our design team in early allows us to align structural elevations and drainage plans to make the edge perfect — both visually and mechanically.
Design Options: Single, Double, and Perimeter Overflow
There’s more than one way to achieve the infinity effect:
- Single-edge infinity — one spillover edge, often oriented toward a view
- Double-edge — two sides vanishing for a more dramatic wraparound look
- Full perimeter overflow (mirror pool) — all sides spill evenly, creating a level glass-like surface
Mirror pools are especially popular in contemporary architecture, where symmetry and reflection are part of the aesthetic language.
Each option requires different hydraulic and structural systems which is why few builders can execute them flawlessly.
How We Maintain That “Mirror” Finish
Infinity edges require more than good design. They demand precise ongoing calibration.
We install adjustable weirs, automatic leveling systems, and surge tanks that balance volume even under heavy use.
This ensures that the water always flows evenly over the edge, maintaining the signature “liquid glass” effect.
Why Precision and Stability Matter
Many builders attempt infinity pools without proper engineering – undersizing the catch basin, neglecting reinforcement, or misaligning spillways.
The result? Uneven edges, noisy hydraulics, and endless maintenance headaches.
At Southern Pool Designs, we build above code and design with margin. Not guesswork.
That’s how our mirror pools stay silent, balanced, and visually perfect long after completion.
A Statement Piece That’s Built to Perform
A true infinity edge pool isn’t just about looks. It’s a symbol of craftsmanship, precision, and performance.
We combine architectural vision with engineering discipline. Creating pools that are as reliable as they are beautiful.
Whether you’re designing a modern masterpiece overlooking Lake Nona or a coastal retreat in Viera, our team ensures that every drop of water moves exactly as it should.
Bottom Line
An infinity or vanishing edge pool isn’t a trend. It’s an architectural statement that transforms a property.
But behind the beauty lies a level of engineering that only comes from experience, precision, and craftsmanship.
At Southern Pool Designs, we’ve mastered that balance.
We don’t just build the illusion of perfection. We engineer it.
