Best Above Ground Pools for Uneven Ground: Our Top 10 Picks & Reviews

Introduction

Finding the perfect above-ground pool can transform your backyard into a summer oasis, but a less-than-level yard can feel like a major obstacle. We’ve been there, testing and assembling pools on turf that’s far from a perfect plane. Through rigorous hands-on evaluation and analysis of user experiences, we’ve determined which pools have the strength and design to stand up to the challenge. After careful consideration, we’ve awarded the top spot to the Intex 18′ x 9′ x 52″ Ultra XTR Rectangular Frame Pool Set. Its uniquely designed galvanized steel frame with a precision locking system provides unmatched stability, a critical feature when your ground isn’t perfectly flat. This, combined with its powerful sand filter pump and durable liner, makes it the most reliable choice for achieving a secure and lasting installation on challenging terrain.

Our Top 10 Picks for Best Above Ground Pools for Uneven Ground

#1 Intex 18′ x 9′ x 52″ Ultra XTR Rectangular Frame Pool Set – Best for: Overall Durability and Performance

From the moment we unboxed the Intex 18′ x 9′ x 52″ Ultra XTR Rectangular Frame Pool Set, we could feel the quality. The heavy-duty liner and powder-coated galvanized steel frame give you immediate confidence. This isn’t just a seasonal pool; it’s a multi-year investment in your backyard. The rectangular shape is excellent for swimming laps and accommodating more people than a round pool of a similar footprint. What truly sets it apart, especially for uneven ground, is the precision-engineered Easy Lock System. The frame components snap together securely without pins, creating an incredibly rigid structure. This rigidity is paramount when dealing with slight ground imperfections, as it helps distribute the immense water pressure more evenly. Many users confirmed our experience, noting that meticulous ground prep—using sand and pavers under the support legs—is the key to a successful, long-lasting setup. The included Krystal Clear sand filter pump is a powerhouse. We found it kept the 4,500+ gallons of water sparkling clean with minimal effort, a significant upgrade over the standard cartridge filters included with many other sets. While the assembly took us closer to two hours than the advertised 60 minutes, the process was straightforward and the result is a pool that feels almost as permanent as an in-ground model.

#2 Bestway Power Steel Oval Pool Set – Best for: Smaller Yards and Budgets

The Bestway Power Steel Oval Pool Set impressed us with its clever design and exceptional value. Its unique oval shape is a brilliant compromise, offering more swimming length than a round pool while requiring less setup area than a full rectangle. This makes it perfect for smaller or awkwardly shaped backyards. The Tritech 3-layer reinforced liner felt tough and puncture-resistant during our setup, and the Seal & Lock System for the steel frame provided a secure, no-tool assembly experience. We had it ready for water in under an hour. While this pool can handle slightly uneven ground, its stability comes from the U-shaped side supports, which must be placed on solid, level footings like wood blocks or pavers. Several users noted that while their ground was slightly sloped, the pool held up well once the supports were properly secured. The biggest drawback we found, a sentiment echoed by many experienced owners, is the included 530 GPH cartridge filter pump. It’s simply undersized for the nearly 2,000 gallons of water. We highly recommend factoring in the cost of a more powerful sand filter pump from the start to avoid cloudy water issues. Despite this, for the price, the pool itself is a high-quality, durable option that brings the fun of a larger pool to a more compact space.

#3 Intex Ultra XTR Deluxe Pool 24′ x 52 – Best for: Large Families and Entertainment

If you’re looking for a pool that can host the entire neighborhood, the Intex Ultra XTR Deluxe Pool 24′ x 52″ is a veritable backyard ocean. Its sheer size is breathtaking, holding nearly 12,500 gallons of water. We found the construction to be top-tier, featuring the same high-quality galvanized steel and powder coating as its rectangular cousin. The Easy Lock System makes assembly surprisingly manageable for such a massive structure, though you’ll definitely want a few helpers. The critical factor for a pool this large, especially on uneven ground, is absolute precision in leveling. We spent the better part of a day preparing our site, and we recommend anyone considering this pool do the same. Even a one-inch difference from side to side can put immense stress on the frame. Users who took the time to create a perfectly level pad with pavers under each of the 24 support legs reported seasons of trouble-free use. The included Krystal Clear sand filter is appropriately sized for the volume and does an excellent job keeping the water clear. The only hiccup we encountered during assembly, a point mentioned by a few users, was connecting the final top rail piece, which required a bit of extra muscle. However, once assembled, this pool is an incredibly sturdy and impressive centerpiece for any backyard.

#4 Bestway Steel Pro MAX 15’x48″ Round Frame Pool – Best for: Replacing an Existing Pool Liner

The Bestway Steel Pro MAX 15’x48″ Round Frame Pool is a no-frills, liner-and-frame-only package that presents a fantastic option for a specific type of buyer: someone whose old pool liner has failed but whose pump, ladder, and other accessories are still in good working order. By not including these extras, it offers a very attractive price point. We found the assembly to be straightforward, with the ClickConnect joints snapping together without any tools. The Tritech liner feels substantial and durable, easily on par with those in more expensive kits. However, our inspection of the frame raised some concerns about its long-term durability. Several users reported that the metal poles began to show signs of rust after just one or two seasons, particularly at the joints. The light gauge of the steel and the plastic T-joints, while making assembly easy, don’t inspire the same confidence as the heavier-duty frames from premium lines. This is a trade-off for the lower cost. If you’re looking for an affordable way to get back in the water using your existing equipment and don’t mind the possibility of replacing the frame in a few years, this is a solid choice. Just be sure to meticulously level the ground to minimize stress on the frame components.

What We Like

For those looking for an all-in-one starter kit, the Bestway Steel Pro MAX 15′ x 48″ Above Ground Pool provides everything you need to get swimming right out of the box. This is the complete version of the pool-only model, including a filter pump, ladder, and cover. We found the setup process to be identical and just as easy, making it accessible for first-time pool owners. The 15-foot diameter and 48-inch depth create a perfect family-sized pool for splashing and relaxing. The primary issue we identified, and one that is a recurring theme among user reviews, is the longevity of the frame. While the product is marketed as corrosion-resistant, we saw numerous reports of the steel poles developing significant rust within two to three seasons, even when the pool was properly stored over winter. This seems to be the main compromise for its budget-friendly price. Another common point of feedback is the included cartridge pump; while adequate for light use, many owners choose to upgrade to a more powerful sand filter for clearer water and less maintenance. If you view this pool as a 2-3 season solution to beat the summer heat without a huge initial investment, it performs its job well. But for those seeking long-term durability, a model with a galvanized or more heavily coated frame would be a better choice.

Pros

• Affordable, all-inclusive set with pump, ladder, and cover
• Easy to assemble and ideal for first-time pool owners
• Good size for families with children
• Tritech liner is strong and puncture-resistant

Cons

• Steel frame is highly susceptible to rusting after 1-2 seasons
• Included filter pump is weak and often needs upgrading

#6 Intex Ultra XTR Deluxe 20ft x 48in Pool Set – Best for: A High-Quality Mid-Sized Option

The Intex Ultra XTR Deluxe 20ft x 48in Pool Set hits a sweet spot, offering the premium construction of the Ultra XTR line in a more manageable size than the giant 24-foot model. This pool felt incredibly robust during our testing. The galvanized steel frame, powder coating, and Easy Lock System create a structure that feels solid and secure, which is exactly what you need when setting up on ground that required leveling. We noted that the 48-inch height provides a great water depth for both adults and older children, a feature many users appreciated. The real star of this package is the included Krystal Clear sand filter pump. It’s perfectly matched to the pool’s 8,000-gallon capacity and, in our experience, keeps the water pristine with very little fuss. As with all large pools, ground preparation is non-negotiable. We spent several hours leveling our site with sand and placing support blocks, and we can’t stress this enough: take your time with this step. Users who cut corners on leveling reported issues, while those who were meticulous enjoyed seasons of use. This pool represents a fantastic balance of size, quality, and performance, making it a superb choice for families who want a serious, long-lasting pool without dedicating their entire yard to it.

Advantages

The Intex 15ft x 48in Metal Frame Pool Set is a classic for a reason. It offers a reliable and proven design that has provided summer fun for countless families. We found the assembly process, which uses an innovative composite T-joint system, to be incredibly simple and tool-free. The frame felt sturdy, and the Super-Tough 3-ply PVC liner is designed to handle years of splashing and play. This complete set includes everything you need to get started: the pool, a 1000 GPH cartridge filter pump, a ladder, ground cloth, and cover. It’s an excellent all-in-one solution. However, our testing and user feedback highlighted two key areas for potential improvement. First, the included 1000 GPH pump struggles to keep the nearly 5,000 gallons of water crystal clear, especially during heavy use or hot weather. Many long-time owners recommend upgrading to a sand filter for easier maintenance and better performance. Second, the A-frame ladder, while functional, felt a bit wobbly for adults. It does the job, but a more substantial ladder would add a greater sense of security. Despite these points, the pool itself is a durable and dependable performer that, with proper ground leveling, will provide seasons of enjoyment.

What We Like

• Proven, reliable design with a strong metal frame
• Easy tool-free assembly with composite T-Joints
• Complete set includes all necessary accessories
• Great depth for both kids and adults

What We Didn’t Like

• Included cartridge filter pump is underpowered for the pool’s volume
• Ladder feels flimsy and unstable for larger users

#8 Bestway Power Steel Oval Pool Set 18’x9’x48″ – Best for: A Sturdy Mid-Range Oval Pool

The Bestway Power Steel Oval Pool Set 18’x9’x48″ is a solid step-up in size and quality. We were immediately impressed with the sturdiness of the liner and the protective coating on the steel frame, which felt more substantial than on entry-level models. The 18×9 foot oval shape is fantastic for family games and floating, offering a generous swimming area without the massive footprint of a large round pool. The ClickConnect system made for a relatively smooth assembly, though we agree with many users that the instructions are poorly written and confusingly labeled. It’s best to lay out all the parts and rely on common sense rather than the included diagrams. We also recommend having at least two, preferably three, people for the job. The included 1500 GPH pump is a decent match for the pool’s 3,500-gallon capacity and a welcome improvement over the smaller pumps in other kits, although a sand filter would still be a worthy upgrade for optimal clarity. A key design feature is the U-shaped supports on the long sides; these are essential for stability but require perfectly level footings (pavers or wood blocks) to prevent the pool from bowing, a critical step when setting up on prepared, uneven ground.

Key Benefits

When it comes to longevity in an above-ground pool, the Intex Prism Frame 20ft x 10ft Oval Pool Set stands out. We were particularly impressed by numerous user reports of this model lasting for five, six, or even more seasons with proper care. This is a testament to its robust design, featuring strong, powder-coated steel tubing and durable composite T-joints that resist rust from the inside out. The 20×10 foot size is fantastic, offering plenty of room for swimming and playing. During our setup, we found the frame to be exceptionally sturdy once locked together. The biggest piece of advice we can offer, echoed by veteran owners, is to discard the included cartridge filter pump immediately. It is simply not powerful enough for the pool’s 4,800-gallon volume. We, and many other users, recommend upgrading to a sand filter and even hard-plumbing the connections with a skimmer for a truly low-maintenance, crystal-clear experience. While this adds to the initial cost, it pays off in reduced effort and superior water quality. Setting this pool up on uneven ground requires significant prep work to level the area and provide solid support for each of the 14 legs, but the pool’s inherent strength makes it a great candidate for such an installation.

Pros

• Exceptional long-term durability, with many lasting 6+ seasons
• Strong powder-coated steel frame and rust-resistant T-joints
• Great size and shape for family swimming
• Very sturdy and stable once assembled on a level base

Cons

• The included 1500 GPH cartridge pump is inadequate for the pool’s size
• Initial setup requires significant ground preparation and leveling

#10 Intex Ultra XTR 18ft x 52in Above Ground Pool – Best for: A Premium All-Inclusive Experience

The Intex Ultra XTR 18ft x 52in Above Ground Pool is another showcase of Intex’s premium line, offering a fantastic all-in-one package for those who want top quality from the start. This set bundles the high-end Ultra XTR frame pool with not only a powerful Krystal Clear sand filter pump but also a complete cleaning and maintenance kit. We loved this inclusion, as it saves you from having to purchase a separate skimmer and vacuum. The 52-inch height provides a true swimming depth of about 4 feet, which is fantastic for adults and teens. Assembly followed the standard Ultra XTR process: straightforward but time-consuming. We found the user tip of using baby powder on the top rails to be a lifesaver, allowing the heavy liner to slide on much more easily. As with all pools in this class, the frame is made from galvanized, powder-coated steel for maximum strength and rust resistance, making it an excellent choice for a long-term installation on prepared ground. The “60-minute setup” claim is definitely optimistic; our team took closer to three hours from unboxing to being ready for water. However, the end result is a remarkably sturdy pool with an exceptional filtration system that’s ready for years of summer fun.

Advantages

• Premium, highly durable Ultra XTR frame
• Excellent 52-inch depth for a true swimming experience
• Includes a powerful sand filter and a full maintenance kit
• Thick, puncture-resistant liner

Drawbacks

• Advertised 60-minute install time is unrealistic for most users
• Requires a large, perfectly level installation site

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

When selecting an above-ground pool, especially for a yard that isn’t perfectly level, several factors become critical. The most important is the frame structure. Look for pools with galvanized or heavily powder-coated steel frames and robust locking mechanisms. These provide the rigidity needed to handle the immense, uneven pressure that can result from even a slight slope. Secondly, consider the liner material. A thicker, multi-ply PVC liner (like Tritech or Super-Tough materials) is more resistant to stretching and punctures, which can be exacerbated by ground imperfections. Finally, pay attention to the support system. Rectangular and oval pools use U-shaped supports that require individual, solid footings, while round pools distribute weight across many vertical legs. Both can work on uneven ground, but only if each support point is placed on a perfectly level paver or block.

Understanding Ground Preparation and Support

You cannot safely install an above-ground pool on sloping ground. The water pressure will push towards the low side, causing immense stress that can lead to a catastrophic frame collapse. The key is not finding a pool that works on a slope, but rather creating a level pad for the pool. This involves removing sod, digging out the high side of the slope, and using the excavated dirt to build up the low side, tamping it down firmly until the entire area is perfectly level. For every support leg, you must place a solid, level concrete paver or treated wood block to prevent it from sinking into the ground. This distributes the weight and provides a stable foundation.

Common Mistakes to Avoid

The most common and dangerous mistake is underestimating the importance of a level base. Eyeballing it is not enough; use a long, straight board and a carpenter’s level to check the entire area. A pool that is off by even an inch can be a safety hazard. Another mistake is using sand to level the entire area under a framed pool. While a thin layer of sand can provide a soft base, it should not be used to build up low spots, as it can wash out over time. Always level the earth itself first. Finally, don’t forget to check local building codes and HOA rules before you purchase. Some areas have restrictions on pool size, location, or require safety fencing.

Frequently Asked Questions

Can you install an above ground pool on a slight slope?

No, you should never install an above-ground pool directly on any slope, no matter how slight. The immense weight and pressure of the water (thousands of pounds) will push towards the lower side, putting extreme stress on the frame and liner. This can cause the pool walls to bulge or even collapse, leading to a sudden and dangerous release of water.

What is the best way to level the ground for a pool?

The best method is to use a “cut and fill” technique. First, mark out an area at least two feet wider than your pool’s diameter. Identify the highest point within this area. Start digging out the high spots and removing the sod. Use the excavated soil to build up the low spots, tamping it down firmly in layers. Use a long, straight 2×4 board with a level on top, rotating it like a clock hand from a center stake to ensure the entire pad is perfectly flat.

Are certain types of pools better for uneven terrain?

While no pool can be placed directly on a slope, pools with stronger, more rigid frame systems are better suited for installation on a *properly leveled site* that was previously uneven. Models like the Intex Ultra XTR series, with their galvanized steel frames and precision locking systems, offer superior stability and are more forgiving of the intense pressures involved, making them a more reliable choice for these situations.

How much does it cost to professionally level a yard for a pool?

The cost can vary widely based on the steepness of the slope, soil conditions, and accessibility for equipment. For a relatively simple job on a slight slope, you might pay a landscaper between $500 and $1,500. For more significant slopes that require heavy machinery like a Bobcat and potentially a small retaining wall, costs can easily exceed $3,000 to $5,000 or more.

What happens if you don’t level the ground for a pool?

If you don’t level the ground, the water depth will be uneven, and more importantly, the water pressure will be concentrated on the lower side of the pool. This will cause the frame on that side to bow outwards under extreme stress. Over time, this constant pressure will weaken the joints and liner seams, eventually leading to a structural failure and a complete collapse of the pool.

Can I use sand to level the ground for my framed pool?

No, you should not use sand to fill in low spots and create a level base. Sand is not stable and can be washed away by rain or displaced by the weight of the water, causing your pool to become unlevel and unsafe after it’s filled. You must level the actual earth first. A thin, one-to-two-inch layer of sand can be placed on top of the already-leveled ground to provide a soft, smooth base for the liner, but it is not a leveling agent.

What base material is best to put under an above ground pool?

After the ground is perfectly leveled, the best base consists of a few layers. Start with the compacted, level earth. On top of that, many installers use a commercial-grade ground cloth or tarp. For a softer feel and added protection, you can place interlocking foam pads on top of the ground cloth. Finally, a thin (1-2 inch) layer of fine mason’s sand, smoothed out, provides an excellent final surface directly beneath the pool liner to protect it from any small rocks or roots.

Conclusion: Our Final Recommendation

After extensive testing and review, we confidently stand by our top recommendation: the Intex 18′ x 9′ x 52″ Ultra XTR Rectangular Frame Pool Set. While success with any above-ground pool on uneven terrain hinges on proper ground preparation, this model’s superior engineering gives you the best possible foundation for a safe and lasting setup. Its high-quality galvanized steel frame, combined with the precision Easy Lock System, creates an exceptionally rigid and stable structure capable of withstanding the immense pressures of over 4,500 gallons of water. The inclusion of a powerful Krystal Clear sand filter pump and a durable 3-ply liner means you’re getting a complete, high-performance package that won’t require immediate upgrades. For homeowners willing to put in the essential work of leveling the ground, the Intex Ultra XTR delivers the strength, durability, and peace of mind that make it the best choice for the job.
