The Modern Small Pool—Designed Your Way

SPA + POOL = SPOOL

What Is a Spool?

A spool—short for spa + pool—started as a solution for tight backyards. A compact body of water that could cool you off in summer, heat up in winter, and fit where full-scale pools couldn't. Over time, spools evolved into something much bigger than their footprint.

At Ecopool, we took that idea and rebuilt it from the ground up. Our architectural spools aren't downsized compromises. They're fully custom, performance-engineered pools that are fully designed and custom-made to your needs.

Above-Ground Small Spool

Above-ground doesn't mean temporary.
And it definitely doesn't mean ugly.

ARCHITECTURAL DESIGN

Above-Ground Spools That Look Intentional

Our above-ground architectural spools are designed to be seen, not buried. Clean lines. Precision steel construction. Exterior finishes that feel closer to modern architecture than backyard equipment.

  • Faster installation
  • Lower excavation costs
  • Ideal for rocky or sloped sites
  • Perfect for modern homes and courtyards

Many clients intentionally keep their spool fully above ground—or partially recessed—using elevation as a design feature.

Above-Ground Architectural Spool

FULLY CUSTOM SIZES

Not Preset Boxes

Most "spools" come in fixed molds: 10×6, 12×7, maybe 14 feet if you're lucky. Ecopool spools don't work that way. We build custom pools and spas in any length, width, and depth, designed around how you want to use the water—not what a factory mold allows.

8×8 Heated Spool

Compact hot tub alternative for intimate spaces.

10×16 Architectural Plunge

Modern statement piece for design-forward homes.

Narrow Lap Spool

Tucked along a fence line for daily exercise.

Spool with Premium Zycore Interior

COMMERCIAL-GRADE INTERIOR

A Surface That Redefines the Spool Experience

Most spools rely on acrylic shells or plaster interiors. Both age poorly.

  • Smooth, comfortable surface—never abrasive
  • Non-porous, algae-resistant interior
  • No plaster cracking, etching, or staining
  • Designed to last decades, not years

For a spool—where you're often sitting, leaning, and relaxing—surface comfort matters more than ever.

YEAR-ROUND COMFORT

Heated. Cooled. Used Year-Round.

Our pools are insulated steel structures, not bare concrete shells. That insulation dramatically reduces heat loss in winter and heat gain in summer.

  • Faster heating
  • Lower energy costs
  • Stable water temperatures
  • Comfortable shoulder-season swimming

In cold months, your spool becomes a large in-ground hot tub. In summer, it stays refreshingly cool.

Year-Round Spool Hot Tub
Exercise-Ready Spool

FITNESS & WELLNESS

Exercise-Ready Spools (Without the Swim-Spa Look)

Ecopool spools can be configured with resistance swimming systems, allowing you to swim or walk against a current in a compact footprint—without the bulky appearance of most acrylic swim spas.

  • Low-impact fitness
  • Rehabilitation
  • Daily movement in small spaces
  • Year-round training

Because the pool is architectural—not molded plastic—you don't sacrifice aesthetics to get performance.

DESIGNED FOR EVERY BACKYARD

Custom-Designed

Spools exist because not every property can accommodate a traditional pool. Ecopool expands where spools can go even further.

Small or Narrow Yards

Perfect for urban homes, courtyards, and atriums where space is at a premium.

Hillsides & Sloped Lots

Above-ground and partially inground installs eliminate the need for deep digging.

Rocky Soil Sites

Where excavation is expensive, Ecopool spools save time, money, and frustration.

SPOOL VS TRADITIONAL OPTIONS

Why Ecopool Architectural Spools?

Concrete Spools

  • Long build times
  • High maintenance
  • Poor insulation
  • Plaster resurfacing every 7–10 years

Acrylic Swim Spas

  • Limited sizes and layouts
  • Bulky appearance
  • Hard to integrate architecturally
  • Fixed factory mold options

Ecopool Architectural Spools

  • Modern steel construction
  • Insulated, energy-efficient shell
  • Long-life interior surface
  • Install almost anywhere
Smart Spool Technology

SMART TECHNOLOGY

Technology That Actually Makes Ownership Easier

Small pools shouldn't mean big maintenance. Ecopool spools can be equipped with:

  • Ultraviolet water disinfection
  • Variable-speed energy-efficient pumps
  • Robotic pool cleaning
  • Smart water monitoring

Together, these systems reduce chemical use, cleaning time, and ongoing effort—making spool ownership feel effortless instead of fussy.

WHO AN ECOPOOL SPOOL IS FOR

Is an Architectural Spool Right for You?

Ecopool spools are ideal if you want:

  • A design-forward pool, not a backyard appliance
  • Full customization without full-scale pool complexity
  • A year-round water feature
  • Faster installation and predictable costs
  • A pool that feels intentional—even when compact

Especially popular with modern homes, design-driven renovations, and homeowners who value performance as much as aesthetics.

Spool FAQs

Common questions about Ecopool architectural spools.

What is a spool pool?

A spool—short for spa + pool—is a compact body of water that sits somewhere between a hot tub and a swimming pool. Bigger than a spa but smaller than a conventional pool, spools are often heated, jet-driven, and typically used for lounging, cooling off, or light exercise. Ecopool's architectural spools take this concept further with fully custom sizes, modern steel construction, and performance engineering.

What sizes do Ecopool spools come in?

Unlike most spools that come in fixed molds, Ecopool builds custom pools in any length, width, and depth. Common configurations include 8×8 heated spools, 10×16 architectural plunge pools, narrow lap spools, and integrated pool + spa combinations. Our modular system scales cleanly in 4-foot increments—or fully custom by quote.

Can I DIY install a spool?

Yes, an Ecopool is super DIY friendly and can save you a ton of money off of your total project cost. With a prefabricated design, an Ecopool is the ideal candidate for a DIY job. Pools arrive factory-built and ready to install with minimal on-site work required.

How long does it take to install an Ecopool spool?

Typical timeline: Site prep takes 1–2 days, pool placement takes hours, and final connections take days. In many cases, homeowners are swimming within a week of delivery. No drawn-out construction zones, no weather delays, no endless subcontractor scheduling.

Can Ecopool spools be heated?

Yes! Our spools can be heated and even ordered with a pool heater. Because our pools are insulated steel structures (not bare concrete), they heat faster, maintain stable temperatures, and cost less to operate. In cold months, your spool becomes a large in-ground hot tub. In summer, it stays refreshingly cool.

What is the interior surface made of?

Ecopool uses a commercial-grade reinforced polymer membrane—the same technology trusted in high-end European pools, resorts, and municipal installations. It's smooth, comfortable, non-porous, and algae-resistant. No plaster cracking, etching, or staining. Designed to last decades, not years.

Can spools be used for exercise?

Yes! Ecopool spools can be configured with resistance swimming systems, allowing you to swim or walk against a current in a compact footprint—without the bulky appearance of most acrylic swim spas. Ideal for low-impact fitness, rehabilitation, daily movement, and year-round training.
