A small pool is any swimming pool under 400 square feet—typically ranging from 8'×8' up to 20'×20'. Far from a compromise, a small pool delivers the full swimming experience with lower costs, faster installation, and a fraction of the maintenance. Ecopool builds every small pool from high-strength structural steel with insulated walls, smart water monitoring, and a Zycore™ interior membrane—the same technology found in our largest custom designs.
Not every backyard needs an Olympic-sized pool. What it needs is a space that transforms daily life—a place for morning laps, afternoon cool-downs, and evenings under the stars. Ecopool's small pools pack the full S-Series platform into a compact footprint: aerospace-grade tubular steel, R-10 insulation, UV-C sanitation, and intelligent water monitoring. Every feature of a full-size pool, scaled to fit your space.
Whether you want a compact plunge pool for cooling off, a cocktail pool for entertaining, or a spa-pool hybrid for wellness—Ecopool builds it from the same steel platform, to any size you need.

Less mass than a concrete pool of equal size.
Cheaper to maintain than gunite pools.
Urban lots, side yards, courtyards, rooftops—spaces that would reject a traditional pool welcome a small Ecopool. The modular steel structure arrives factory-built and ready to install, without the excavation crews, rebar trucks, and months of disruption that concrete demands.
Because every panel is precision-cut in our Salado, Texas facility, we build to the inch. Odd dimensions, L-shapes, and tight setbacks are standard practice, not special orders.
Starting at just $22,320, a small Ecopool costs a fraction of a traditional gunite build—and arrives with the pump, filter, UV-C sanitation, and smart monitoring already integrated. No separate bids for plumbing, electrical, and equipment pads. No six-figure surprise at the end of a five-month build.
R-10 insulated walls reduce heating costs by up to 80 percent, while micro-dosing chemistry cuts chemical spend by roughly 40 percent. The smaller water volume amplifies every efficiency gain.
A small pool holds less water, which means less chemical to balance, less energy to heat, and less time to clean. Ecopool takes it further with commercial-grade UV-C disinfection and a micro-dosing chlorine pump that keeps free chlorine near drinking-water levels—0.5 ppm.
An onboard robotic cleaner maps the floor automatically, and smart sensors track pH, ORP, and temperature around the clock. You get a text when something needs attention. Most days, it won't.
Every Ecopool is custom-built. Choose a standard size or specify your own dimensions down to the inch. With our modular steel platform, small pools can be rectangular, L-shaped, or fully custom—inground, above-ground, or partially recessed.
Our smallest configurations start at 8'×8'—just 64 square feet of water, yet fully equipped with filtration, UV-C sanitation, and smart monitoring. At this size, heating is nearly instantaneous and chemical consumption is minimal. Ideal as a cold plunge for athletic recovery, a heated soak, or a courtyard water feature that doubles as a pool.
For families who want real swimming space without a massive build, the 12-to-16-foot-wide range delivers. Room for laps, a baja ledge for lounging, and enough depth for diving boards or tanning shelves. These mid-range small pools are the most popular sizes we build—large enough to swim in, small enough to heat efficiently and maintain effortlessly. You can even add an integrated spa for year-round relaxation.
Every small Ecopool is built on the same high-strength tubular steel platform as our largest installations. Dual hot-dip-galvanized skins sandwich a closed-cell polyurethane core rated at R-10. The Zycore™ interior membrane resists algae, staining, and UV damage for decades. At a compact size, these engineering advantages compound—less surface area to heat, fewer gallons to treat, and a rigid monocoque structure that shrugs off ground movement without the cracking that plagues small concrete shells.
Every small Ecopool can be installed fully inground for a flush, traditional look; raised as an above-ground architectural statement with optional viewing windows; or partially recessed as an S-Series Canvas wrapped in stone, brick, or any cladding material. The same steel structure supports all three approaches—decide during planning, not during fabrication.
A small Ecopool arrives on a single truck, fully fabricated with plumbing, insulation, and interior membrane already in place. Single-module designs are ready for water in as little as 30 minutes after placement. Even multi-module small pools assemble in under two days—no crane, no rebar, no weather delays.
Compare that to four-to-six months for a concrete pool of the same size, and the math speaks for itself.
Every small pool shares the same S-Series platform—aerospace-grade tubular steel, insulated core, and intelligent water management. Choose the installation style that fits your vision.

Common questions about small swimming pools, sizing, costs, and installation.
Our smallest pool is 8'×8'—just 64 square feet. It's fully equipped with the same filtration, UV-C sanitation, and smart monitoring found in every Ecopool. This size is popular for cold plunges, heated soaks, and compact courtyard installations.
Ecopool small pools start at $22,320, which includes the pool structure, pump, filter, and UV-C sanitation system. Traditional concrete pools of similar size typically cost $80,000–$150,000+ and take months to build. Ecopool delivers a stronger, smarter pool at a fraction of the price—and installs in days.
Absolutely. Every Ecopool can be installed fully inground, above-ground, or partially recessed. The same steel structure supports all three configurations, so you choose your installation method during planning without any change to the pool itself.
Single-module small pools (up to approximately 8'×20') can be placed and ready for water in as little as one day. Preplumbed models need only 30 minutes to connect the pump and filter. Multi-module designs assemble in under two days by a two-person crew—no crane or rebar required.
Yes. A narrow 8'×20' or 12'×24' pool provides a genuine swim lane for laps, water aerobics, and resistance training. Paired with an optional swim jet or tether system, even an 8'×12' pool can deliver an effective cardio workout. Check out our spools and lap pools for exercise-focused configurations.
Small pools are ideal for year-round heating. The lower water volume heats faster and the R-10 insulated walls reduce heat loss by up to 80 percent compared to uninsulated concrete. A standard heat pump brings a small Ecopool to temperature in hours, not days, and holds it there efficiently through winter.
A well-designed small pool adds both lifestyle value and resale appeal. Buyers increasingly favor low-maintenance outdoor amenities over large, high-upkeep installations. A compact Ecopool with smart monitoring and steel construction positions a property as modern and move-in ready—without the maintenance concerns that scare buyers away from older gunite pools.
"Small pool" describes any compact swimming pool, while "plunge pool" specifically refers to a pool designed for wading and cooling off rather than lap swimming. All plunge pools are small pools, but not all small pools are plunge pools—a 12'×20' small pool with a full-depth swim lane and baja ledge is a different experience from an 8'×8' cold plunge. Ecopool builds both.
Ecopool small pools can be built up to 9 feet deep, though most compact designs range from 4 to 5.5 feet. Depth is fully customizable during the design phase—add a shallow baja shelf at one end and a deeper plunge zone at the other, or keep a consistent depth throughout.
Yes. Ecopool's prefabricated design makes small pools one of the most DIY-friendly pool options available. The pool arrives fully assembled with preplumbed connections—you need a level prepared area, a final plumbing hookup (about 30 minutes), and an electrician to run power to the pump. Many homeowners save significantly on installation by handling site prep themselves.
