A large swimming pool changes the way you live. It turns a backyard into a destination—a place where morning laps, afternoon pool parties, and evening swims under the stars all happen in the same week. Ecopool builds large pools from 400 to over 1,200 square feet using aerospace-grade tubular steel, delivered factory-built and installed in days instead of months. Whether you want an inground pool, an above-ground architectural statement, or a canvas-clad design, every large Ecopool is custom-sized to your yard and your ambitions.
Every large Ecopool is built on the award-winning S-Series platform—the same aerospace-grade steel, insulated core, and intelligent water management, scaled to whatever size your backyard demands. Choose how you want it installed.
Fully buried for a clean, flush-with-deck finish. The classic choice for expansive backyards where the pool blends into the landscape.

Traditional large pools mean months of construction, cracking concrete, and six-figure budgets. Ecopool's modular steel system ships factory-finished and connects on-site in days—no rebar, no cure time, no weather delays. You get a pool that's bigger, stronger, and ready faster than anything concrete can deliver.
A large pool doesn't just hold more water—it holds more life. Space for a baja ledge where guests lounge half-submerged. Room for corner entry steps that double as seating. Enough length for a proper volleyball net or basketball hoop without crowding swimmers.
With Ecopool, large doesn't mean complicated. The same modular steel panels that build an 8-by-20 pool scale effortlessly to 16-by-40, 20-by-40, or beyond. Every inch is engineered to the same aerospace-grade standard—so going big never means going soft on quality.

A large pool gives you something a small pool simply can't: uninterrupted swimming distance. At 40, 52, or 60 feet in length, an Ecopool becomes a genuine lap pool—long enough for fitness training, aquatic therapy, or just the meditative rhythm of swimming end to end.
Pair that length with widths up to 20 feet and depths reaching 9 feet, and you have a pool that accommodates diving, water sports, and multi-lane swimming without compromise. Whether you're training for a triathlon or teaching your kids to swim, a large Ecopool gives everyone room to move.
A large swimming pool isn't just about volume—it's about freedom. Freedom to add features, host gatherings, swim real distances, and design a backyard that feels like a private resort. With Ecopool's steel construction and modular engineering, going big is faster and more affordable than you'd expect.
Small pools force trade-offs: stairs or a ledge, a deep end or a shallow play area. A large pool eliminates the compromise. Add a full-width baja shelf for lounging, integrated entry steps at one end, and a 6-foot deep zone for diving—all in the same pool. Include a swim-up bar ledge and still have 30+ feet of open swimming lane.
With widths from 12 to 20 feet and lengths stretching past 60 feet, Ecopool's large pools give you the canvas to design the backyard you've been imagining—without cutting a single feature from the list.
Ecopool's modular panel system means your large pool doesn't have to be a plain rectangle. L-shapes wrap around patios. T-shapes create separate swimming and lounging zones. U-shapes turn a single pool into a private courtyard. Each configuration uses the same structural steel—no custom engineering delays, no structural compromise.
Looking for something truly unique? Ecopool designs pools for commercial properties, swim schools, and residential estates where standard dimensions don't apply. If you can draw it, we can build it.
Building a large pool from concrete means more rebar, thicker walls, and exponentially longer cure times. Steel doesn't work that way. Ecopool's 80-ksi tubular steel frame carries load through geometry, not mass—so doubling the pool's footprint doesn't double the complexity. Each modular panel connects tube-to-tube on-site, forming a monocoque shell that's six times stronger than 8-inch concrete and entirely immune to cracking.
Dual hot-dip-galvanized skins sandwich R-10 closed-cell insulation, keeping heat in during winter and chemical costs low year-round. The structure can be lifted by a single corner with minimal flex—proof that scale and strength aren't mutually exclusive.
A larger pool doesn't mean more maintenance. Ecopool's embedded sensor array monitors pH, ORP, and temperature continuously—the same system used in Olympic facilities. Data flows to your phone in a single dashboard, and a commercial-grade UV-C reactor paired with micro-dosing chemistry keeps free chlorine near 0.5 ppm, the same level as drinking water.
No salt generators corroding your coping. No stabilizer tablets clouding the water. Just clean, balanced chemistry managed by algorithms—whether your pool holds 5,000 gallons or 25,000. Explore our smart pool technology to learn more.
Every large Ecopool is fabricated in our precision manufacturing facility in Salado, Texas. CNC plasma machines cut each tube. Hot-air welders lay membrane seams under controlled temperature and pressure. Dimensional lasers verify alignment before shipping. When the modules arrive at your home, two technicians assemble the full pool on-site—no crane, no rebar, no cure time. Multi-module large pools are typically ready for water in 1–3 days.
A 16-by-40 Ecopool is four modular sections. A 20-by-60 might be six. Each section is built to the same exacting standard—insulated, skinned, membrane-welded, and laser-verified—then shipped on a standard flatbed. On-site, tube-to-tube joints lock the sections into a continuous monocoque with no weak points at the seams.
This is how Ecopool delivers large pools without large-pool headaches. No excavation surprises. No six-month construction timelines. No weather-dependent concrete pours. Just precision components that click together with aerospace discipline.
Large pools are historically energy hogs—massive heaters, oversized pumps, and chemical bills that climb with every gallon. Ecopool rewrites that equation. Continuous R-10 insulation cuts heat loss by up to 80 percent. Variable-speed pumps draw a fraction of the energy. Optional solar integration can bring the entire system to net-zero on an annualized basis.
Micro-dosing chemistry reduces chemical consumption by roughly 40 percent compared to traditional pools. No stabilizer byproducts. No salt damage to landscaping. A large Ecopool is the most sustainable way to swim big. Learn how our Zycore™ interior contributes to lower maintenance costs.
Ecopool's Architectural 3D Membrane transforms large pool interiors from functional waterproofing into a sensory experience. German-embossed textures inspired by natural sandbars and layered stone balance grip and glide. The non-porous Zycore™ composite resists algae, staining, and chemical damage far better than plaster, fiberglass, or tile—and it never needs resurfacing. Available in designer shades from Mediterranean blues to dramatic black sapphire.
Family backyards. Swim schools. Boutique hotels. Therapy and rehabilitation centers. Ecopool's large pool range serves them all. The same structural steel and intelligent monitoring that protects a residential pool scales to commercial applications where code compliance, durability, and water quality are non-negotiable.
Whether you need a 16-by-40 backyard oasis or a 20-by-60 training facility, every Ecopool ships with the same warranty, the same factory precision, and the same commitment to zero-defect construction.
