ONE POOL PLATFORM. THREE WAYS TO INSTALL.

The S-Series Steel Pool

Concrete cracks. Fiberglass fades. The S-Series was designed to replace both. Built from aerospace-grade tubular steel, every S-Series pool can be installed fully inground, onground as an architectural feature, or partial inground with custom cladding. Same engineering. Same water quality. You choose how it lives in your backyard.

THE S-SERIES RANGE

Choose Your Installation Style

Every S-Series pool shares the same steel architecture, insulated core, and intelligent water management. The difference is how it sits on your property.

S‑Series Inground Steel Swimming Pool

S‑Series Inground

Fully buried for a clean, flush-with-deck finish. The traditional pool look with anything-but-traditional engineering underneath.

Architectural S‑Series Steel Swimming Pool

S‑Series Architectural

Fully onground with sculptural lines and a minimalist silhouette. No excavation required — a bold statement piece that stands on its own.

S‑Series Canvas Steel Swimming Pool

S‑Series Canvas

Partial inground with a blank exterior ready for stone, stucco, brick, or any cladding. Looks like it was designed by your architect.

Built Different.
Tubular Steel Architecture.

While others pour concrete that cracks within a decade, the S-Series is built around 80-ksi tubular steel — the same engineering principles used in aircraft fuselages. Precision-welded into a monocoque frame so rigid, the entire vessel can be lifted by a single corner with minimal flex.

Wall deflection under full hydrostatic pressure measures less than 1/16 inch across 20 feet. That's six times stiffer than 8-inch concrete — and entirely immune to the micro-fractures and concrete cancer that plague traditional pools.

INSULATED PANELS WITH R-10 PERFORMANCE

Insulated Core Technology

Dual hot-dip-galvanized steel skins sandwich a closed-cell polyurethane core rated at R-10 — the same logic as a modern jet fuselage. Heat stays in during winter. Excess warmth is expelled in summer.

The result is a thermally stable pool that protects water chemistry, deters algae before it can form, and cuts heating costs by up to 80%.

CLEARER WATER. LESS CHLORINE.

Intelligent Water Management

A commercial-grade UV-C reactor deactivates 99% of viruses and bacteria in a single pass. Downstream, a micro-dosing pump holds free chlorine near 0.5 ppm — the same level as municipal drinking water.

No vapor. No chemical odor. No bleached swimsuits. Just water that's cleaner than what most people drink.

Concrete Cracks. Salt Corrodes. Pumps Scream.
We Replaced All of It.

Most pools still rely on cracking concrete shells, corrosive salt cells, and single-speed pumps that waste electricity and sanity. These compromises have survived for decades because nobody offered a real alternative. So we built one — from the ground up. High-strength tubular steel that outlasts gunite. Micro-dosing chemistry that eliminates salt damage. Variable-speed equipment that runs in near silence. Every system reimagined, not patched.

Modern 8x20 S-Series Steel Swimming Pool

BUILT IN A FACTORY, NOT A BACKYARD

Factory Precision

Every S-Series is fabricated in a controlled manufacturing facility. CNC plasma tables cut each tube. Hot-air welders seal every seam under repeatable conditions. Hydrostatic load testing and waterproof verification happen before shipping — not after.

Delivery arrives on a single truck. Two technicians, one to three days, no crane, no rebar, no weather delays. Factory tolerances, field-proven.

INGROUND. ONGROUND. YOUR CALL.

Install It Anywhere

The S-Series isn't limited to one installation style. Bury it flush with your patio for a traditional inground look. Set it onground as a sculptural architectural feature with finished exterior panels. Or go partial inground and clad the exposed walls in stone, stucco, or brick to match your home.

Sloped lots, elevated decks, tight side yards — the modular steel platform adapts to sites where concrete would require months of excavation, forming, and curing.

Ecopool Zycore Architectural 3D Membrane Close-Up

STRONGER THAN CONCRETE. SMOOTHER THAN TILE.

Architectural 3D Membrane & Zycore™

The interior of every S-Series is finished in Zycore™ — a commercial-grade composite that fuses polymer layers with a high-strength polyester matrix. Tensile strength near 3,200 psi, several times that of standard concrete. UV stabilizers are co-extruded into the membrane so color and integrity endure decade after decade.

German embossing technology presses natural textures — rippled sandbars, layered stone — into the surface, balancing grip and glide so bare feet feel secure without abrasion. Unlike plaster, it never chalks. Unlike fiberglass, it never crazes. Unlike tile, there's zero grout to maintain. The smooth, non-porous surface stabilizes water chemistry and resists algae on contact.

SILENT, SMART, SELF-ADJUSTING

Quiet Intelligence

Micro-sensors track pH, ORP, and temperature every hour. A predictive processor interprets the data and adjusts chemistry before deviations become visible. A 24-volt robotic cleaner maps the floor, scrubs an optimized path, and returns to dock — all without you lifting a finger or hearing a sound.

Welder Crafting an Ecopool Steel Pool Frame

85% LESS MATERIAL THAN CONCRETE

Measured Impact

High-strength steel requires 85% less mass than a concrete pool of equal capacity — yet carries greater load. R-10 insulation cuts heat-loss energy by up to 80%. Micro-dosing chemistry trims chemical use by roughly 40% and eliminates stabilizer byproducts entirely.

Every steel tube, insulation board, and membrane sheet enters a recycling pathway at end of life. Projected lifespan: 40+ years.

MODULAR. MOVABLE. BUILT TO ADAPT.

Adaptive Design

Every S-Series pool bolts together through tube-node interfaces. That means it can be relocated without demolition, expanded without re-engineering, or transitioned from onground to inground as your property evolves.

This modularity protects your investment and the environment. At end-of-life, high-strength steel re-enters the metals stream at high value — nothing goes to landfill.

The Vision

The S-Series is for people who want proof, not promises. A steel vessel that keeps water immaculate, energy use near zero, and maintenance limited to a glance at your phone. Inground, onground, or partial — the installation adapts to your site. The performance doesn't change.

From order to first swim, the timeline is measured in weeks. From then on, performance is measured in data you can see, verify, and trust.
