Lucas Congdon is kind of a mad scientist with a jackhammer. If you’ve ever sat through an episode of Insane Pools: Off the Deep End, you know exactly what I’m talking about. By the time Insane Pools Season 3 rolled around on Animal Planet, the stakes weren't just about digging a hole in the dirt anymore. It was about moving literal tons of Pennsylvania fieldstone and creating ecosystems that looked like they’d been there since the Jurassic period.
Most reality TV home Reno shows feel staged. You know the drill: a couple "discovers" a leak, there’s a fake argument about the budget, and everything is magically fixed in forty-four minutes. Lucas Lagoons is different. Season 3 felt grittier. The builds were bigger. We’re talking about projects where the crane rentals alone probably cost more than my first house.

What Really Happened During Insane Pools Season 3
People still search for this season because it represents a peak in "aquatic architecture." During these episodes, Lucas and his team—Old Man, Sunshine, and Crash—stopped just building pools and started building destinations.
One of the standout projects was the "Mountain Lodge" build. This wasn't just a place to do laps. They had to figure out how to integrate a massive, multi-ton stone waterfall with a custom spa that looked like a natural hot spring. The engineering required for these Season 3 builds is actually insane when you break it down. You aren't just pouring concrete. You’re balancing the weight of massive boulders against the structural integrity of a pool shell, all while ensuring the plumbing for a grotto doesn't leak five years down the road.
Honestly, the chemistry of the crew is what kept people coming back. You had Lucas, the visionary who speaks to stones, and then you had the guys on the ground actually trying to make his "napkin sketches" a reality. It’s that tension between high-concept art and "how do we get this forklift through a three-foot gate" that made Insane Pools Season 3 so watchable.
The Technical Magic Behind the Grottos
Let’s talk about the grottos for a second. In the third season, the grottos became more complex. A "Lucas Lagoons" grotto isn't a plastic shell from a big-box store.
They use a mix of natural stone and carved concrete to create spaces where you can actually sit behind the waterfall. The trick is the "curtain." If the water flow isn't calibrated perfectly, you just get sprayed in the face. If it’s too thin, the effect is lost. In Season 3, they mastered the acoustics of these spaces. They started looking at how sound bounces off the stone so that when you’re inside the grotto, the outside world basically disappears.
- Natural Stone Selection: Lucas often sources specific rocks that match the local geography, even if it means shipping them across state lines.
- The "Bio-Fall" System: Many of these pools use advanced filtration that mimics natural streams, reducing the "chemical smell" of traditional chlorine pools.
- Zero-Entry Features: We saw more "beach entries" this season, which are notoriously hard to waterproof where the "sand" meets the deep end.
Why This Season Felt Different
Money. Or rather, the lack of fear regarding it.
The clients in Insane Pools Season 3 seemed to have completely leaned into the "lifestyle" aspect. We saw a shift from "I want a pool" to "I want a private resort." This was the season of the double-decker waterfalls and the fire-on-water features.
Adding fire to a pool isn't just about a gas line. You have to manage the heat so it doesn't crack the surrounding stonework or melt the high-end finishes. The team started using more automation too. By Season 3, clients could control the entire "insane" environment—the lights, the pumps, the fire pits—from an iPad. It was tech meeting nature in a way that hadn't been seen on the DIY Network or Animal Planet before.
The Reality of "Insane" Budgets
One thing the show doesn't always spell out is the cost. If you're watching Insane Pools Season 3 and thinking, "Hey, I want that," you need a reality check. These aren't $50,000 backyard upgrades.
Most of these projects start in the mid-six figures and can easily climb north of $1 million. The stone alone is a fortune. Then you factor in the specialized labor. You can’t just hire a local handyman to carve a custom lagoon. You need artisans. Lucas himself has often mentioned in interviews that the "show" price and the "real world" price can vary based on site conditions.
If they hit palmetto roots or Florida limestone (caprock) that requires a different type of excavator, the budget bloat is real. Season 3 showed a few of these "uh-oh" moments, though they usually ended with a beautiful drone shot and a happy family in bathing suits.

Real-World Lessons from Lucas Congdon
What can a regular homeowner actually take away from Insane Pools Season 3? You might not have a million bucks, but the design principles still apply.
First: Lighting is everything. Lucas uses LED uplighting on the trees and inside the waterfalls. It changes the pool from a black hole at night into a piece of art.
Second: Leveling. Most people think a pool has to be flat. Lucas uses the "elevation" of the yard—even if he has to build it himself with dirt—to create layers. Layers create interest. They create "rooms" in an outdoor space.
Third: Plantings. The "lagoon" look isn't just the water. It’s the tropicals. It’s the palms and the ferns that hide the pool equipment. In Season 3, the landscaping became just as important as the masonry.
What Most People Get Wrong About the Show
There’s a common misconception that these pools are high-maintenance nightmares. Actually, because of the way the Lucas Lagoons team builds them, they are often more efficient than old-school pools.
They use oversized plumbing and high-efficiency pumps. The "natural" look often hides very sophisticated cleaning systems. However, you can't just ignore a lagoon. Debris gets caught in the rock crevices. You have to be diligent about skimming. If you let algae get a foothold in a rock-heavy pool like the ones in Insane Pools Season 3, you’re going to have a bad time. You need a pressure washer and a lot of patience.
The Legacy of the Season 3 Finale
By the end of the season, the show had cemented a specific aesthetic. It moved away from the "blue rectangle" that has dominated American suburbs since the 1950s. It proved there was a massive market for "experiential" backyards.
The "Insane" part of the title isn't just hyperbole. It refers to the scale. While the show has had different iterations and specials, Season 3 remains the benchmark for when the builds went from "cool" to "how is that even possible?"
Actionable Steps for Your Own Backyard Build
If you’re inspired by the work seen in Insane Pools Season 3, don't just start digging. There's a process to getting that lagoon look without losing your shirt.
- Prioritize the "Anchor" Stone: If you can't afford a whole rock wall, invest in three or four massive "character" boulders. Place them so they break the waterline. It immediately grounds the pool.
- Focus on Variable Speed Pumps: These are the backbone of the "waterfall" look. You can dial them back for a trickle when you're reading, or crank them up for a roar when you're hosting a party.
- Use Darker Liners or Finishes: Lucas rarely uses bright "public pool" blue. He uses greys, blacks, and deep greens. This makes the water reflective like a natural lake and helps heat the pool naturally using the sun.
- Integrate the "Hidden" Spa: Instead of a plastic tub sitting on the deck, build your spa into the rockwork. Season 3 showed that a "spillover" spa is the best way to get both a focal point and a functional heater.
- Audit Your Drainage: The biggest mistake people make when mimicking these "insane" designs is forgetting where the rain goes. Large rock structures can act like dams. Ensure your contractor has a plan for runoff so your "lagoon" doesn't end up in your living room during a storm.
The brilliance of the show wasn't just the final reveal. It was the reminder that water is the most versatile building material we have. Whether it's a small backyard in Sarasota or a massive estate, the principles of flow, sound, and natural materials can turn a boring lot into something that feels alive.
Expert Insight: If you're looking for the specific contractors or products used during the season, look for "PebbleTec" finishes and "Jandy" pool equipment, which were staples of the high-end builds during this era of the show.
