When it comes to selecting the perfect design for your backyard pool, shape plays a significant role. Two of the most popular choices are round and rectangular pools. While both offer their own unique advantages, the decision often comes down to personal preferences, space limitations, budget, and intended use. In this detailed article, we’ll explore the pros and cons of each pool type, compare their features, and help you determine whether a round pool is better than a rectangular pool.
Understanding the Basics: Round vs. Rectangular Pools
Before diving into the details, let’s understand what qualifies as a round or rectangular pool.
Round Pools
A round pool is exactly what it sounds like: a circular-shaped pool. These pools can be above-ground or in-ground. They typically offer a compact design, making them ideal for small spaces.
Rectangular Pools
Rectangular pools are the standard and most recognizable pool shape. They are usually longer and narrower, which makes them attractive for lap swimming and a more formal aesthetic.
Design and Aesthetics
The visual appeal of your pool is often the first consideration when planning your backyard oasis.
Visual Impact of Round Pools
Round pools offer a soft, flowing appearance that can complement natural and informal landscapes. Their curved edges bring a sense of gentle elegance to any backyard setting. If your backyard has a natural, rustic, or contemporary bohemian style, a round pool can serve as a striking centerpiece without overwhelming the space.
Pros:
- Offers a soft, organic feel
- Blends well with freeform or curved landscaping
Cons:
- Might not suit modern or minimalist architecture
- Less traditional compared to rectangular pools
Visual Impact of Rectangular Pools
Rectangular pools are synonymous with clean lines, symmetry, and a polished look. They are often preferred in contemporary and modern architectural settings because of how well they balance with geometric structures.
Pros:
- Classic, timeless shape
- Matches well with modern or formal landscapes
Cons:
- Clinical or boxy appearance in natural settings
- Less unique than other pool shapes
Functionality and Use
Of course, looks aren’t everything. The way you use your pool matters a lot. Let’s compare the two shapes in terms of functionality.
Swimming and Exercise
If you plan to use your pool for exercise or lane swimming, the shape of your pool can significantly affect your experience.
Round Pools
While round pools can work for casual swimming, their lack of clear direction and limited length makes them unsuitable for lap swimming. You’ll quickly reach the edge and need to turn around. That said, they’re fun and great for younger swimmers or relaxation.
Rectangular Pools
Rectangular pools, particularly those that are 25 or 50 feet long, are perfect for swimming laps and keeping fit. Their long, straight layout allows you to swim uninterrupted. For serious swimmers, the rectangular pool is by far the better option.
Entertaining and Social Use
Pools are often social hubs. So, what shape facilitates better group activities?
Round Pools
Round pools tend to be more compact and allow swimmers to interact from nearly every angle. This makes them ideal for social gatherings, especially if you have a smaller backyard or want a close-knit environment.
Rectangular Pools
Rectangular pools can have both ends dedicated to depth changes—shallow for lounging and deep for diving—making them versatile. Larger models can accommodate many people at once and allow for organized games like water volleyball.
Accessibility and Pool Entry
In terms of accessibility, some pool shapes accommodate features like steps, benches, or tanning ledges better than others.
Round Pools
Their curved design can make integrating steps awkward without compromising on space. However, they often come with a simple, central step or a bench around the edge.
Rectangular Pools
Rectangular pools allow greater flexibility in planning various entryways—like a gentle slope entry, built-in benches, or multiple steps across the shallow end. Many also integrate a tanning ledge for sunbathing and entry/exit points.
Space Requirements and Placement
Pools come in many sizes, and the shape affects how they fit into your landscape. Here’s how each type handles space dynamics.
Round Pools
Round pools are excellent when you have limited space. A 16-foot diameter round pool can fit in spaces where a rectangular pool of the same size could not, due to space geometry and turning radius. Their compact nature also makes them ideal for:
- Small backyards or lots with space constraints
- Backyards with irregular shapes or existing landscaping
Rectangular Pools
Rectangular pools tend to take up more linear space. If your backyard is long and narrow, you’re in luck. But if you have an odd or compact yard, a rectangular pool may require major landscaping to accommodate.
If your goal is to create a resort-style backyard, a large rectangular pool can serve as a standout feature when space allows.
Cost Considerations
Cost is always a crucial factor when building or purchasing a pool. Let’s break down how each pool shape compares in terms of price.
Round Pools
Round pools—especially above-ground options—are often more budget-friendly. The standardized factory manufacturing cuts down on expenses. Furthermore, their smaller footprints mean less excavation, less water, and fewer landscape adjustments required.
Rectangular Pools
Rectangular pools, particularly in-ground models, can be more costly. Factors such as:
- Custom design or engineering
- Larger size options
- Equipment like filtration, heater, and lighting systems
…can increase the final cost.
Additionally, the more surface area a rectangular pool has, the more expensive ongoing maintenance can be.
Maintenance and Durability
You’ll live with your pool for many years, which means thinking about longevity, durability, and regular upkeep is essential.
Round Pools
Many round pools—especially above-ground ones—are constructed from steel or aluminum frames with vinyl liners or resin walls. While modern materials have improved dramatically, they may not match the durability of concrete or fiberglass in-ground options.
Because they have less surface area, round pools:
- Require less water
- Have less space to clean
- Exhibit less evaporation (especially if covered)
But vinyl liners may need replacement every 5–9 years.
Rectangular Pools
Depending on construction material—fiberglass, concrete, or vinyl—maintenance varies:
| Material | Maintenance Level | Lifespan |
|---|---|---|
| Concrete | High | 10+ years, requires resurfacing |
| Fiberglass | Low | 25+ years |
| Vinyl | Moderate | 5-9 years, liner replacement needed |
With more surface area, rectangular pools may cost more to heat, filter, and clean. However, they are more versatile in terms of structural upgrades over time.
Installation and Customization Options
A critical decision point is how easy your pool is to install and how much customization is possible.
Round Pools
Round pools, especially prefabricated ones, can be set up in a matter of hours. Above-ground models are typically DIY-friendly, making them an appealing option for budget-conscious homeowners.
They do have standard sizes, which limits customization.
However, adding features like:
- Portable filtration systems
- Simple decking or stone walkways
- Ladders and covers
…can easily be done.
Rectangular Pools
Rectangular in-ground pools can be fully customized. You can specify:
- Depth variations
- Built-in benches, steps, or spa areas
- Infinity or vanishing edges
But they come at the cost of longer installation times and higher expense.
Resale Value and Long-Term Appeal
A pool adds value to your home—but which shape makes it more attractive on the market?
Round Pools
Above-ground round pools often do not add substantial value and can even deter some buyers. In-ground round pools, while less common and distinctive, are not as universally appealing to a broad buyer base.
Rectangular Pools
A well-built, properly maintained rectangular in-ground pool typically increases property value by 5–10%, especially in competitive real estate markets. Because of its timeless design, a rectangular pool tends to be more appealing to a variety of buyers.
Common Types of Pools by Shape
Let’s review the different kinds of pools and how the round vs. rectangular debate fits into the broader pool landscape:
In-Ground vs. Above-Ground
- In-Ground: Offers durability, deeper designs, and often rectangular shapes. High initial cost but better resale impact.
- Above-Ground: Common in round shapes, often plastic or metal, low initial cost, easy to install but limited permanence.
Liner Pools vs. Concrete
Round pools often rely on vinyl liners for affordability. In contrast, rectangular pools are frequently constructed from concrete for longevity and luxury. Each material has pros and cons regarding cost, maintenance, and customizability.
Alternative Shapes
Options like L-shaped, keyhole, and freeform pools exist, but they generally stem from rectilinear or curved fundamentals. Round and rectangular are the two most frequently chosen due to their wide availability and practical attributes.
Environmental Impact and Sustainability
As sustainability becomes increasingly important, understanding the environmental footprint of pools is wise.
Water Consumption
Round pools generally consume less water due to their smaller surface area and depth. Rectangular pools with greater volume can hold more water, increasing water use and heating.
Round Pool Average Water Volume:
- 16-foot diameter pool: ~6,600 gallons
Rectangular Pool Average Water Volume:
- 16′ x 32′ by 5′ deep pool: ~19,200 gallons
Energy Efficiency
Larger rectangular pools require more energy for heating and circulation. Using solar covers and energy-efficient pumps can help reduce impact in both types.
Eco-Friendly Materials
Some modern pool manufacturers are beginning to incorporate recycled resin, environmentally friendly liners, and non-chemical filtration systems. This is worth exploring when selecting a pool shape and model brand.
Final Thoughts: Is a Round Pool Better Than a Rectangle?
Deciding whether a round pool is better than a rectangular one requires weighing several key factors:
If You Prioritize:
Entertainment and Close Interaction
Then a round pool is a great option. It allows people to face each other, encourages conversation, and feels more intimate.
Exercise or Lap Swimming
Then a rectangular pool is the clear winner. Its straight, long design makes for effortless laps and serious use.
Space Constraints
If space is tight, a round pool may offer the flexibility needed without sacrificing aesthetics or usability.
Aesthetics
For a modern or minimalist outdoor space, a rectangular pool offers clean lines. For organic or garden-centric setups, a round option may fit better.
Long-Term Value
In-ground rectangular pools add more value to a home than round in-ground or above-ground pools.
In short, neither shape is categorically “better”. The best pool shape depends entirely on your personal needs, the landscape of your outdoor space, and how you plan to use the pool.
If you’re a fitness enthusiast with a large rectangular backyard—go with a rectangular in-ground pool. If you’re starting small, have kids, and enjoy a cozy backyard setup—then a round pool makes perfect sense.
Ultimately, each pool shape brings unique strengths to the table, and your final decision should reflect your lifestyle and vision for your outdoor area.
So, whether you choose round, rectangular, or something in between, your ideal pool is one that brings joy, functionality, and relaxation to your home.
What are the main differences between round and rectangular pools?
Round pools and rectangular pools differ primarily in shape, which influences their aesthetics, functionality, and suitability for different spaces. Round pools typically provide a more traditional, casual appearance and are often easier to install, especially in smaller or irregularly shaped yards. They tend to have a more uniform depth and are usually associated with above-ground pool setups, though some in-ground versions also exist.
Rectangular pools, on the other hand, are often considered more modern and sleek in appearance. They are more commonly found as in-ground installations and typically have a consistent depth across the width, offering a more versatile space for swimming laps and formal entertaining. Their angular shape also allows for better integration with decked or landscaped areas, making them a popular choice for homeowners seeking a sophisticated look and enhanced functionality.
Which pool shape is better for swimming laps?
When it comes to swimming laps, a rectangular pool is generally the better choice. Its straight sides and uniform width provide a more practical and efficient lane for consistent swimming. Many rectangular pools are designed with lap swimming in mind, often being longer in length and deeper in the middle sections to accommodate uninterrupted strokes.
While round pools can be used for exercise, their shape makes it more challenging to swim laps in a straight line, especially in smaller sizes. Swimmers may find themselves frequently changing direction or adjusting their strokes due to the curved edges. However, for casual exercise or water therapy, round pools can still be suitable, especially if the model is large enough to provide adequate swim space.
Which pool is more cost-effective to install?
Round pools are often more cost-effective to install than rectangular pools, particularly for above-ground models. Because of their symmetrical design, they require fewer materials for both the pool structure and the surrounding support systems. The installation process is typically simpler and faster, which further reduces labor costs. This makes them an attractive option for budget-conscious homeowners.
Rectangular pools generally come with higher installation costs due to their more complex construction and support requirements. Especially in the case of in-ground models, the need for reinforced walls and additional materials increases the overall expense. However, some economies of scale may apply for larger round pools, meaning that at a certain size, the price difference between the two shapes might be less significant.
How does pool shape affect maintenance and cleaning?
Pools with a round design often have better water circulation due to their curved walls, which can help distribute chemicals more evenly and reduce stagnant water spots. This natural flow can make maintaining proper water chemistry slightly easier. In addition, some automated pool cleaners perform better in round pools because they can navigate the continuous curved surfaces without getting stuck in corners.
Rectangular pools, with their straight edges and sharp corners, may require more attention during cleaning as these areas can trap debris and algae if not properly maintained. However, the flat walls and predictable layout can make certain maintenance tasks like vacuuming or installing water features more straightforward. Ultimately, the difference in maintenance is manageable with the right equipment and regular care, regardless of the shape.
Which pool type offers more flexibility in design and landscaping?
Rectangular pools tend to offer greater flexibility when it comes to integrating with landscapes and outdoor designs. Their angular lines complement patios, decks, and walkways, and they can easily be customized with features like tanning ledges, built-in seating, or infinity edges. This makes them a popular option for homeowners who want a sleek, designer look that matches an outdoor living space.
Round pools, while less flexible in terms of custom features, can provide a unique and charming focal point, particularly for backyard spaces with a more casual or rustic style. They work well in naturalistic or compact environments and are often easier to place in odd-shaped or limited spaces. However, because of their classic shape, they may not offer the same level of architectural versatility as rectangular pools.
Which pool shape is better suited for families?
The suitability of a round or rectangular pool for families often depends on the intended use and available space. Round pools are often a good choice for families who prioritize ease of installation and have limited yard space. Their open, less segmented design can be excellent for younger children to swim and play in, without distinct deep or shallow ends that may pose challenges in supervision.
Rectangular pools can provide more defined areas, such as a deep end for diving or a shallow end for younger swimmers, allowing families to customize the pool for varied activities. They also give more freedom in hosting pool parties or using the space for structured play and games. For larger families or those who enjoy recreational swimming alongside lap swimming, the versatility of a rectangular pool can offer more long-term satisfaction.
Which pool shape is more energy-efficient?
Round pools can be more energy-efficient in certain scenarios thanks to their compact, symmetrical shape and better water circulation. The consistent flow helps distribute heat and chemicals more effectively, which can reduce the amount of energy and chemicals needed to maintain optimal pool conditions. This can translate to lower operating costs over time, especially for smaller, residential models.
Rectangular pools may require slightly more energy to heat and circulate water, depending on their size and depth. However, modern technology such as energy-efficient pumps, solar heating, and pool covers can help offset any inherent differences in efficiency. Ultimately, both pool shapes can be made energy-efficient with proper equipment and maintenance practices tailored to the owner’s specific needs and climate conditions.
