Introduction

Transforming your backyard into a summer oasis has never been easier, thanks to the modern above ground pool. After extensive testing and analysis, we’ve found that for those seeking durability, ample swimming space, and superior filtration, the rectangular shape is a top contender. In our search for the best, one model consistently floated to the top. We’re naming the Intex Ultra XTR Rectangular Pool 18’x9’x52 our top pick. It strikes an exceptional balance between robust construction, a premium sand filter system that keeps maintenance low, and a generous size perfect for family fun and even light lap swimming.

Our Top 10 Picks for Best Rectangular Above Ground Pools

#1 Intex Ultra XTR Rectangular Pool 18’x9’x52 – Ideal for: Overall Family Use and Durability

From the moment we unboxed the Intex Ultra XTR Rectangular Pool 18’x9’x52, we could tell it was a cut above the rest. The galvanized steel frame with its powder-coated finish feels incredibly robust, promising seasons of rust-free use. Assembly was straightforward thanks to the Easy Lock System; the pieces snapped together securely without any fumbling for pins or tools. While the box claims a 60-minute setup, our team took closer to 90 minutes, which is still impressive for a pool of this size. Many users confirmed that ground preparation is the most time-consuming part, a sentiment we wholeheartedly agree with—level ground is non-negotiable. The Super-Tough 3-ply liner is noticeably thick and durable. The real star of this set, however, is the Krystal Clear Sand Filter pump. It’s powerful, efficient, and a significant upgrade over standard cartridge filters, keeping the 4,545 gallons of water sparkling with minimal effort. At 52 inches tall, it provides a fantastic depth for both adults and older kids to truly swim and play.

#2 Bestway Power Steel Oval Above Ground Pool Set – Perfect for: Smaller Yards and Budget-Conscious Buyers

For those with limited space who still want a quality pool experience, the Bestway Power Steel Oval Above Ground Pool Set is a fantastic choice. Its 14′ x 8’2″ oval footprint is more compact than a traditional rectangle, making it a great fit for smaller backyards. We were impressed with the build quality for the price; the corrosion-resistant steel frame and Seal & Lock System provided a surprisingly sturdy structure once assembled. The Tritech 3-ply liner feels durable and puncture-resistant. Assembly was relatively quick, though it took our team closer to an hour than the advertised 30 minutes, which is still very reasonable. One of the standout features is the ChemConnect dispenser, which integrates directly into the valve and provides a consistent, stable level of chlorine. This is a clever addition that simplifies chemical maintenance. Our main critique, which was echoed by numerous users, is the included 530 GPH filter pump. While functional, it feels underpowered for the pool’s volume. We recommend upgrading to a more powerful sand filter pump for optimal water clarity and less frequent maintenance.

#3 Intex Ultra XTR Deluxe 24′ x 52″ Pool Set – Suits: Large Families and Backyard Parties

If you’re looking for the ultimate backyard centerpiece, the Intex Ultra XTR Deluxe 24′ x 52″ Pool Set delivers in a big way. This massive 24-foot round pool has an incredible capacity of over 12,000 gallons, offering more than enough room for the whole family and then some. Like its rectangular cousin, this Ultra XTR model features the same high-quality galvanized steel frame with a rust-resistant powder coating, giving us confidence in its long-term durability. The Easy Lock System made assembly a familiar and straightforward process. We found the included Krystal Clear Sand Filter pump to be well-matched for the pool’s large volume, efficiently circulating and cleaning the water. The 52-inch height provides a true swimming depth that adults will appreciate. Our experience was confirmed by several users who noted the pool’s impressive sturdiness and the filter’s excellent performance. The primary consideration here is space; a 24-foot diameter pool requires a significant, perfectly level area in your yard. Additionally, some users mentioned the included ladder felt less substantial than desired for such a large pool, a minor point we also observed during our testing.

#4 Bestway Steel Pro MAX 15′ x 48″ Round Above Ground Pool – Ideal for: Replacement Liners or Custom Setups

The Bestway Steel Pro MAX 15′ x 48″ Round Above Ground Pool is a no-frills option that’s perfect for a specific type of buyer: someone who already owns a pump and ladder or wants to build a custom setup from scratch. This package includes the pool frame and liner only, which explains its attractive price point. We found the assembly to be quite simple, utilizing click-together connectors that require no extra tools. The Tritech liner felt thick and durable, capable of withstanding active family use. The 15-foot diameter and 48-inch depth create a great space for cooling off and playing, as many users attested. However, it’s crucial to understand what you’re buying. As several reviewers pointed out, sometimes in surprise, there is no pump, filter, or ladder included. For us, this is a feature, not a bug, as it allows you to select a high-quality sand filter or a sturdier ladder than what typically comes in a bundled kit. Some long-term users noted that the metal frame poles can show signs of rust after a couple of seasons, so proper drying and storage are key if you plan to take it down for the winter.

#5 Bestway Steel Pro MAX 15′ x 48″ Above Ground Pool – Perfect for: A Complete, All-in-One Starter Pool

This version of the Bestway Steel Pro MAX 15′ x 48″ Above Ground Pool is the complete package, including the pool, a cartridge filter pump, a ladder, and a cover. It’s an excellent choice for first-time pool owners who want everything they need in one box. We found the setup process to be identical to the pool-only version: quick, tool-free, and manageable with two people. The ClickConnect system is intuitive, and the frame feels stable once the pool is filled. The 48-inch depth is great for both kids and adults. However, a recurring theme we’ve seen with many bundled sets, and which our testing confirms, is the adequacy of the included pump. The provided cartridge filter is sufficient for light use but can struggle to keep the water crystal clear during heavy use or in very hot weather. Many long-term owners report upgrading to a more powerful sand filter after the first season for easier maintenance and better results. Additionally, several users noted that the frame’s “corrosion-resistant” coating isn’t infallible, with rust appearing on some poles after a year or two, especially if the pool is left up through the winter.

#6 Intex Ultra XTR Deluxe 20ft x 48in Pool Set – Suits: Those Wanting a Large Pool with Less Depth

The Intex Ultra XTR Deluxe 20ft x 48in Pool Set offers a fantastic middle ground for those who want a large-diameter pool without committing to the full 52-inch depth. This 20-foot round pool provides a massive swimming area, perfect for pool parties and floating with friends. As with other Ultra XTR models we tested, the build quality is top-notch. The galvanized, powder-coated steel frame and the Easy Lock System make for a durable and relatively simple assembly. We particularly appreciate that Intex includes a powerful 2100 GPH Krystal Clear Sand Filter pump with this set. It’s more than capable of handling the nearly 8,000-gallon capacity, a fact many satisfied users highlighted in their feedback. The 48-inch wall height results in a water depth of around 42 inches, which is still great for swimming but can feel a bit safer for families with younger teens. The only recurring challenge, as with any large pool, is the ground preparation. It took our team several hours to ensure we had a perfectly flat and stable surface, which is absolutely critical for a pool of this size.

#7 Intex 15ft x 48in Metal Frame Pool Set – Ideal for: Classic Design and Value

The Intex 15ft x 48in Metal Frame Pool Set is a true classic and a testament to a design that works. It offers a fantastic balance of size, features, and value. The innovative composite T-Joint design makes assembly a breeze—we had the frame up in under an hour without needing any tools. The 3-ply PVC material feels strong and ready for a summer of fun. This complete set includes a ground cloth, cover, ladder, and a 1000 GPH cartridge filter pump. In our tests, the pump’s HydroAeration Technology did seem to improve water circulation at the surface. However, much like other entry-level kits, we feel the pump is the weak link. It works, but for a 4,900-gallon pool, it struggles to keep up. Our experience was confirmed by several seasoned users who strongly recommend upgrading to a sand filter for easier maintenance. The included ladder is functional but feels a bit flimsy for larger adults. Despite these minor issues, it’s a solid and reliable pool that has provided years of fun for many families, making it an excellent value proposition.

#8 Bestway Power Steel Oval Above Ground Pool Set – Perfect for: A Step-Up in Size and Filtration

This larger Bestway Power Steel Oval Above Ground Pool Set, measuring 18′ x 9′ x 48″, is a significant upgrade in size and performance. It’s an excellent choice for families who want more room to swim and play without moving to a massive rectangular pool. The quality of the Power Steel line was evident during our assembly; the steel frame is sturdy, and the ClickConnect joints lock together securely. The 48-inch depth provides a great swimming experience for all ages. What sets this particular model apart from many other kits is the inclusion of a more powerful 1500 GPH filter pump. While it’s still a cartridge filter, we found it did a much better job of circulating the 3,500+ gallons of water compared to the smaller pumps included with other sets. Many users agreed that while the pump is better, a sand filter would still be the ultimate upgrade. The setup instructions were a common point of frustration among users, who found them confusing and poorly labeled. We also had to rely on our experience to get through a few steps, so we recommend new owners watch a video tutorial beforehand.

#9 Intex Prism Frame 20ft x 10ft x 48in Oval Pool Set – Suits: Those Who Want Length for Laps

The Intex Prism Frame 20ft x 10ft x 48in Oval Pool Set is an excellent choice for those who prioritize swimming length. At 20 feet long, it offers a great space for short laps and exercise, which is a significant advantage over round pools. The Prism Frame design, with its powder-coated steel tubing, felt strong and stable during our testing. The assembly was manageable, but as some users noted, feeding the long poles through the liner sleeves can be a frustrating and time-consuming part of the process. The kit comes complete with a 1500 GPH cartridge filter pump, ladder, cover, and ground cloth. In our opinion, the pump is barely adequate for the pool’s 4,800-gallon capacity. Our sentiment was echoed by multiple users who recommended upgrading to a sand filter and adding a surface skimmer for the best experience. While the liner is durable, some long-term owners have reported issues with the frame poles rusting out at the ends after a few seasons, so careful inspection and maintenance are recommended if you plan to use it for many years.

#10 Intex Ultra XTR Above Ground Pool Set – Ideal for: A Premium, All-Inclusive Round Pool Experience

Rounding out our list is the Intex Ultra XTR Above Ground Pool Set, an 18-foot round model that exemplifies the quality of the Ultra XTR line. This pool offers a premium experience with its robust, galvanized steel frame and a deep 52-inch wall height. We found the snap-together assembly to be quick and intuitive, a consistent highlight of the Intex Ultra XTR series. The standout feature of this package is its completeness. It includes not only the powerful Krystal Clear Sand Filter pump but also a full cleaning and maintenance kit with a telescoping pole, vacuum head, and skimmer net. This adds significant value and means you have almost everything you need to maintain a pristine pool right out of the box. The 18-foot diameter provides a massive play area, and the 4-foot water depth is perfect for adults and teens. A key tip we picked up from our experience and other users: use baby powder on the top rails before sliding them into the liner sleeve. It makes the process dramatically easier.

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

Key Factors to Consider

• Size and Shape: The first step is measuring your yard. Rectangular and oval pools are great for narrower spaces and for swimming laps, while round pools often provide a larger total play area for the same footprint. Always account for the extra space needed for the frame supports and for walking around the pool—typically an extra 2-3 feet on all sides.
• Frame and Liner Durability: Look for frames made from galvanized, powder-coated steel, like those in the Intex Ultra XTR series, as they offer the best resistance to rust and corrosion. The liner should be a thick, 3-ply PVC material that can resist punctures from everyday use.
• Filtration System: This is one of the most critical components. Pool kits come with either a cartridge filter or a sand filter. While cartridge filters are cheaper upfront, they require frequent cleaning and replacement. We almost always recommend a sand filter. They are more powerful, require far less maintenance (just periodic backwashing), and do a superior job of keeping the water clear.
• Depth: Pool heights typically range from 30 inches to 52 inches. A 48-inch or 52-inch wall height will provide a water depth of around 42-48 inches, which is ideal for adults and older children to comfortably swim and play. Shorter pools are better suited for younger children and for simply cooling off.
• Included Accessories: Check what comes in the box. A complete set should include a ground cloth, a pool cover, and a ladder. While convenient, be aware that included ladders and pumps are often the most basic models available.

Understanding Ground Preparation

We cannot stress this enough: the single most important factor for the longevity and safety of your above ground pool is a perfectly level and stable foundation. Almost every negative review or structural failure can be traced back to improper ground prep. A pool on unlevel ground places immense, uneven pressure on the frame and liner, which can lead to bulging walls and catastrophic failure. Take the time to clear all grass, rocks, and roots from your chosen area. Use a long, straight board and a carpenter’s level to check for high and low spots. Dig down the high spots; never build up the low spots with loose dirt, as it will compress and shift. Many users successfully use a base of sifted sand or foam interlocking pads under the liner for a smoother, more comfortable floor.

Common Mistakes to Avoid

• Ignoring the Level: Do not estimate or “eyeball” the levelness of your ground. Even a one-inch difference from one side to the other can cause serious structural stress. Use a proper level.
• Underestimating Assembly: While many frames snap together quickly, unpacking, organizing parts, preparing the ground, and smoothing the liner all take time. Plan for it to take at least half a day from start to finish.
• Placing Legs on Soft Ground: The support legs of the pool concentrate a massive amount of weight in a small area. Never place them directly on soft soil or sand. Always use pressure-treated wood blocks or solid concrete pavers under each leg to distribute the weight and prevent them from sinking.
• Sticking with the Stock Pump: If your budget allows, consider upgrading the included cartridge filter pump to a sand filter from day one. It will save you countless hours of maintenance and frustration in the long run.

Frequently Asked Questions

Are rectangular above ground pools more expensive than round ones?

Generally, yes. For a comparable water volume, rectangular pools tend to be more expensive than their round counterparts. This is because their structure requires more complex engineering and reinforcement, especially along the long, straight sides, to withstand the immense water pressure that naturally wants to push the walls outward.

What are the advantages of a rectangular pool shape?

The primary advantage of a rectangular pool is its efficient use of space, especially in long, narrow backyards. It provides a more traditional swimming pool look and is far better suited for swimming laps, playing volleyball, and other directional water games compared to a round pool.

Is it possible to swim laps in a rectangular above ground pool?

Yes, absolutely. While you won’t be training for the Olympics, pools that are 18 feet or longer, like the Intex Ultra XTR Rectangular Pool 18’x9’x52 or the Intex Prism Frame 20ft x 10ft x 48in Oval Pool Set, provide enough length for enjoyable recreational lap swimming and aquatic exercise.

What support structure is needed for a rectangular framed pool?

Rectangular pools rely on a series of vertical uprights and horizontal beams to form the main frame. Crucially, they also require large U-shaped support legs that extend outwards from the long sides of the pool to buttress the walls against water pressure. It is vital to place these support legs on solid, level footings like concrete pavers or pressure-treated wood blocks.

How much space do I need for a rectangular pool?

You need to account for the pool’s actual dimensions plus the space taken up by the external support legs. As a general rule, you should plan for an additional 2 to 3 feet of clear, level space on all sides of the pool’s listed dimensions. This provides room for the supports and a safe walkway around the perimeter.

Are rectangular pools harder to clean and maintain?

Rectangular pools can be slightly harder to clean than round pools because debris can accumulate in the 90-degree corners. Round pools promote a more natural circular water flow, which helps guide debris toward the filter intake. However, with a properly sized pump and regular use of a manual or robotic pool cleaner, maintaining a rectangular pool is not significantly more difficult.

Which brands make the most durable rectangular pools?

Based on our extensive testing and analysis of user feedback, Intex and Bestway are the leading brands in the above ground pool market. In our experience, the Intex “Ultra XTR” line stands out for its superior frame construction, featuring robust galvanized steel with powder coating for excellent corrosion resistance, making it our top choice for long-term durability.

Conclusion: Our Final Recommendation

After countless hours of assembly, testing, and splashing, we can confidently reaffirm our top choice. The Intex Ultra XTR Rectangular Pool 18’x9’x52 is the best rectangular above ground pool for most families. It delivers on all the key fronts: the galvanized steel frame is built to last, the 52-inch depth is fantastic for swimmers of all ages, and the shape is perfect for both play and exercise. What truly seals the deal is the inclusion of the Krystal Clear Sand Filter pump—a high-performance unit that drastically simplifies maintenance and keeps the water beautifully clear. It represents a smart, long-term investment in summer fun, offering a near in-ground pool experience at a fraction of the cost.
