7 INTERIOR COLORS

Choose Your Zycore® 3D Interior

Every 20' x 28' S-Series ships with your choice of 7 premium interior finishes—each engineered with Zycore® 3D membrane technology for vivid color, algae resistance, and long-term durability. Choose from Mystic Blue, Aqua Blue, Blue Matrix, Black Sapphire, Deep Sea Blue, Titanium Stone, and Blue Topaz. Each finish transforms the water color and overall feel of the pool, from deep ocean blues to shimmering stone textures. The 6-layer, 70-mil membrane is over 5× stronger than typical above-ground pool liners.

BUILT TO LAST.

60% Stronger Than Gunite Pools

Forget rebar and concrete. The Ecopool uses automotive-inspired construction: multi-layer aluminum panels over a reinforced composite shell. The result? Strength that rivals in-ground pools—at a fraction of the weight.

It ships with ease, installs in hours, and resists warping, corrosion, and impact. You’re not building a pool. You’re assembling an engineered aquatic environment.

FAQs

Frequently Asked Questions about Ecopool S-Series Inground Pools

Can I build any size pool with the S-Series?

Yes. The S-Series uses modular structural steel construction, which means your pool can be built to virtually any length, width, and depth. From a compact 8'×12' plunge pool to a full-size 20'×40' family pool—and everything in between. There are no molds to limit your options. If you can dream it, we can build it.

How deep can an S-Series Inground pool be?

S-Series pools can be built to virtually any depth—from a shallow 3.5' wading area to 8' deep or more. Multi-depth configurations are also available, letting you combine a shallow sun shelf or Baja ledge with a deep end for diving, all in a single pool.

What makes the S-Series different from concrete or fiberglass?

Structural steel. Every S-Series pool is built around an engineered steel frame that's fabricated in our factory and assembled on your site. There's no curing time like concrete, no mold limitations like fiberglass, and no worry about cracking or shifting soil. Steel gives you complete design freedom with the strength of a commercial building.

How long does it take to install an S-Series Inground pool?

Most S-Series Inground pools are installed in 2–5 days once site preparation is complete, depending on the size and complexity of your design. Compare that to 3–6 months for a typical concrete pool. Your pool arrives factory-fabricated and preplumbed—site work is focused on excavation, placement, and final connections.

What is the interior finish made of?

Every S-Series pool features a German-engineered Zycore® reinforced polymer membrane with factory-welded seams. This creates a continuous, watertight interior surface that's smooth, chemical-resistant, UV-stable, and easy to clean. Available in multiple designer colors from bright white to deep charcoal.

Can I add features like a Baja ledge, bench seating, or attached spa?

Absolutely. The modular steel design supports tanning ledges, bench seating, integrated spas, custom entry stairs, and virtually any feature you want. Because there are no molds, we can design and fabricate custom features specific to your pool. Work with our design team to configure yours.
