Rectangular Pool or Freeform Pool- What’s It Gonna Be?
Choosing the shape of your backyard pool is one of the biggest decisions you’ll make when planning an inground oasis. Rectangular pools and freeform pools each bring distinct vibes, practicalities, and considerations to the table. It’s not a choice you can easily undo once the concrete’s poured, so weighing factors like design flexibility, build time, cost differences, and materials is key. At Town & Country Pools, we’ve built thousands of pools since 1977, and we’re here to break down the differences to help you decide—no pressure, just the facts.
Design: Style and Setting
The shape of your pool sets the tone for your entire outdoor space. Rectangular pools are the classic choice, rooted in symmetry and clean lines. Their straight edges and sharp corners naturally complement formal landscapes—think sleek patios, geometric decking, or minimalist gardens. They’re a go-to for homeowners who want a polished, architectural look that mirrors the lines of a modern home. That said, a rectangular pool isn’t stuck in a formal box. With creative decking (curved edges, perhaps), natural stone coping, or lush landscaping, you can soften its edges to blend into a more organic backyard setting.
Freeform pools, by contrast, are all about fluidity. Their irregular, flowing shapes—think kidney beans, lagoons, or custom curves—mimic nature’s contours, making them a perfect fit for rustic or tropical environments. Picture boulders, waterfalls, or winding paths; a freeform pool thrives in that laid-back, natural vibe. It’s tougher, though, to make a freeform pool feel at home in a structured, formal space. Its curves clash with straight lines, so forcing it into a cleanlined setting often looks off. Your backyard’s personality—wild or refined—plays a big role in which shape feels right.
Design also ties to functionality. Rectangular pools shine for lap swimming or organized games like volleyball, thanks to their predictable dimensions. Freeform pools lean toward leisure—lounging, floating, or soaking in a spa-like nook. Think about how you’ll use the pool: exercise or relaxation? That can tip the scales.
Build Time: Straight Lines vs. Curves
How long it takes to build your pool depends partly on its shape. Rectangular pools generally have a simpler construction process. Their straight sides and uniform angles mean less time plotting layouts or shaping rebar—everything’s measured and cut to predictable specs. For a typical project, this can shave off about 10-15% of the build time compared to a freeform pool, assuming similar square footage. The excavation stays straightforward, and the concrete or gunite application follows a grid-like pattern, speeding things along.
Freeform pools, with their custom curves and organic outlines, take more effort. The design phase alone requires extra planning—each bend needs precise mapping to match your vision. Excavation gets trickier, as does forming the structure; workers spend more time sculpting the shape and ensuring the curves hold up under pressure. That adds roughly 10-15% more time to the project. Weather, site conditions (e.g., rocky soil), and size still play bigger roles in the timeline, but shape nudges it one way or the other. If you’re eager to dive in sooner, rectangular might edge out.
Cost: Breaking Down the Percentages
Cost is a top question we hear: “Is a rectangular pool cheaper than a freeform one?” The short answer is no—at its core, pricing hinges on surface area, not shape. A 400-square-foot rectangular pool and a 400-square-foot freeform pool start at the same base cost, whether we’re pouring concrete or gunite. But the real answer gets nuanced, and here’s why.
Rectangular pools often cost 10-20% more overall because of add-ons. Homeowners who pick this shape frequently opt for an automatic pool cover—a safety and maintenance game-changer that only works with straight-edged designs. That feature bumps up the total by a noticeable chunk, depending on the cover’s quality and installation. Without it, though, a rectangular pool stays neck-and-neck with its freeform cousin in price.
Freeform pools can creep 5-10% higher than a bare-bones rectangular build due to complexity. Those curves mean more labor—think extra hours shaping the shell or fitting coping around irregular edges. Landscaping often plays a bigger role too; freeform designs pair with natural features like rockscapes or plants, which can nudge costs up if you go all-in. So, while the base price aligns, a fully decked-out freeform might outpace a basic rectangular pool by a small margin. Your budget and extras dictate the final tally.
Materials: Concrete and Gunite Options
At Town & Country Pools, we stick to durable, customizable materials—concrete and gunite—for both shapes. (No fiberglass here; it’s not our style.) Both options adapt to rectangular or freeform designs, but how they’re applied shifts slightly.
Concrete pools, poured into molds, suit rectangular builds beautifully. The straight forms are easy to set, and the finish—smooth or textured—holds up across flat planes. Gunite, a sprayed concrete mix, is our go-to for flexibility. For rectangular pools, it’s applied evenly over rebar grids, curing into a rock-solid shell. For freeform pools, gunite shines—it lets us sculpt those curves with precision, layer by layer, matching your backyard’s flow. Material costs don’t vary much between shapes (maybe 2-5% more for freeform’s extra gunite finesse), but the application time and skill tilt the labor slightly.
Decking matters too. Rectangular pools often pair with concrete or pavers for a crisp look—cost-effective and quick to lay. Freeform pools might lean toward natural stone or irregular tiles to echo their shape, which can run 10-15% pricier per square foot. Landscaping—say, gravel vs. boulders—also tweaks the material spend. Your aesthetic choices shape the bill as much as the pool itself.
Making Your Choice
So, rectangular or freeform? It’s your call, and there’s no wrong answer. Rectangular pools offer clean design, faster builds, and cover compatibility, with costs spiking only if you add features. Freeform pools bring natural charm and leisurely vibes, with a bit more build time and a slight cost bump for complexity. Both can be stunning in concrete or gunite, tailored to your yard with the right materials.
We’ve guided countless homeowners through this since 1977, and it always comes down to your space and vision. Want a formal retreat with a cover? Rectangular’s your pick. Craving a lagoon-like escape? Freeform fits the bill. Either way, we’re here to weigh the pros and cons with you—site specifics, lifestyle needs, the works.
