Key Features & Specifications

Standout Features

When evaluating if the Intex Ultra XTR pool set is worth it, the features tell a compelling story. This isn’t just a vinyl liner and some poles; it’s an engineered system.

• Ultra XTR Frame Design: The core innovation is the galvanized steel frame with a precision locking system. The components snap together without tools or locking pins, creating a remarkably rigid structure that feels far more solid than traditional frame pools.
• Krystal Clear Sand Filter Pump (Model #26643EG): Included is a 2,650-gallon-per-hour sand filter system. Sand filtration is superior to cartridge filters for larger pools, trapping finer particles and requiring less frequent cleaning—just a weekly backwash.
• Complete Filtration Package: Intex includes a 50lb bag of OptiFlow Premium Filter Sand. This is a huge plus, as it means you can have the filter operational immediately after setup.
• Super-Tough 3-Ply PVC Liner: The pool liner is made from puncture-resistant material with a polyester mesh core for extra strength. It’s designed to withstand the rigors of active families and comes with a repair patch.
• Rust and UV Resistant T-Joints: The critical connection points are infused with UV inhibitors to prevent sun degradation and are engineered for high strength, addressing a common failure point in lesser pools.
• Substantial Size: At 18 feet by 9 feet and 52 inches deep, this oval pool offers over 5,500 gallons of water. It’s large enough for swimming laps, playing games, and cooling off multiple adults and children comfortably.

What’s Included in the Box

Unboxing the Intex Ultra XTR feels like opening a serious piece of equipment. The packaging is robust, with components well-secured to prevent shipping damage. Here’s the complete inventory you can expect:

• The main 3-ply PVC pool liner, neatly folded.
• All galvanized steel frame components (uprights, top rails, bottom rails, and T-connectors).
• The Krystal Clear Sand Filter Pump unit with a 6-function control valve (Filter, Backwash, Rinse, Recirculate, Drain, Closed).
• One 50lb bag of OptiFlow Premium Pool Filter Sand.
• Necessary hoses and connectors to link the pump to the pool’s inlet and outlet.
• A ground cloth to protect the pool liner from beneath.
• A repair patch kit for the liner.
• Comprehensive instruction manuals for both the pool and the filter pump.

The build quality of the individual parts is immediately impressive. The steel feels heavy-duty, the powder coating is even, and the PVC liner is substantially thick. It’s clear this isn’t a disposable seasonal item. One important note: you will need to purchase pool chemicals (chlorine, pH balancers, etc.), a pool vacuum, and a test kit separately. These are essential for proper maintenance but are not included.

How to Use Intex 26355EH Ultra XTR 18ft x 9ft x 52in Above Ground Swimming Pool Set with Sand Filter Pump and OptiFlow 50lb Premium Filter Sand: Complete Guide

Step 1: Site Preparation and Frame Assembly

This is the most critical step. Choose a perfectly level area free of rocks, roots, or debris. Lay down the included ground cloth. The frame assembly is where the Ultra XTR system shines. The pieces truly do snap together without tools. Start by connecting the bottom rails to the T-connectors to form the oval base. Then, insert the upright legs into the T-connectors. Finally, click the top rails onto the uprights. The precision engineering ensures a tight, rattle-free fit. The entire frame can be assembled by two people in about 45 minutes to an hour.

Step 2: Installing the Liner and Filling with Water

Drape the liner over the assembled frame, ensuring it’s centered. Start filling the pool with a garden hose immediately. As the water rises (it will take many hours), smooth out wrinkles from inside the pool and adjust the liner around the top edges. The water pressure will help seat the liner perfectly. Do not leave the empty liner in the sun, as it can heat up and become more prone to damage.

Step 3: Setting Up the Sand Filter Pump

While the pool fills, assemble the sand filter pump according to its manual. This involves filling the filter tank with the included OptiFlow sand—a slightly messy but straightforward job. Connect the hoses from the pool’s water outlet (suction side) and inlet (return side) to the correct ports on the pump. Position the pump on a stable, level surface close to the pool. Plug it into a properly grounded GFCI outlet. Once the pool water level is about halfway up the skimmer opening, you can start the pump on the “Filter” setting to begin circulating and cleaning the water.

Step 4: Daily Operation and Chemical Balance

For daily use, the pump should run for at least 8-12 hours to properly filter the entire volume of water. Use a test kit to check chlorine and pH levels daily, adding chemicals as needed to keep the water safe and clear. The sand filter’s 6-function valve makes maintenance easy. Use the “Backwash” function for a few minutes once a week to clean the sand bed, then “Rinse” for 30 seconds before returning to “Filter.”

Step 5: End-of-Season Winterization

When the season ends, balance the water chemistry, lower the water level below the inlet/outlet ports, and drain the pump and hoses completely. Disconnect and store the pump indoors. Clean and dry the pool cover before use. Proper winterization is key to answering the long-term question of is the Intex Ultra XTR pool set worth it, as it ensures many seasons of use. For a detailed winterization guide, check out our pool care resource.

Step 6: Troubleshooting Common Issues

If the pump loses prime, check for air leaks in the suction hose. If water flow is weak, backwash the filter. If the pool walls are bulging, the ground is likely not level—this is a serious issue that requires draining and re-leveling. Always consult the manual for specific error codes related to the pump.

Performance & Real-World Testing

Testing Methodology

We assembled and used the Intex Ultra XTR pool over an entire summer season (approximately 4 months). It was subjected to regular family use with -4 adults and children, weekend gatherings, and varying weather conditions from intense sun to heavy rain. We monitored setup time, ease of maintenance, filtration effectiveness, and structural integrity.

Performance Metrics

The standout performer was the sand filter system. Compared to Intex’s cartridge filters we’ve used in the past, it maintained crystal clear water with significantly less effort. A weekly backwash was all it needed, whereas cartridges required cleaning every few days under heavy use. The 2,650 GPH flow rate provided strong circulation. The frame’s stability was exceptional; there was zero wobble or flex, even with multiple people in the pool. This directly impacts the Intex Ultra XTR honest opinion—it feels secure and permanent.

Real-World Scenarios

During a birthday party with ten people in the pool, the structure didn’t budge. After a major dust storm, the sand filter, when placed on “Recirculate” with a clarifier, cleared the cloudy water within 24 hours. The pump ran continuously during a heatwave without overheating. These stress tests proved its capability beyond casual use.

Claims vs. Reality

Intex’s claims of “easy assembly” and “rust resistance” held true in our testing. The snap-together frame is genius. However, the claim of “no tools needed” is mostly accurate, though a rubber mallet was helpful to fully seat a few stubborn connections. The “puncture-resistant” liner lived up to its name, showing no wear from normal play. Our testing confirms that for durability and filtration, the Intex Ultra XTR pool set is worth it for those seeking a long-term seasonal solution.

Pros and Cons

What We Loved (Pros)

• Exceptional Frame Stability: The galvanized steel and locking system create a rock-solid structure that inspires confidence.
• Superior Sand Filtration Included: Having a high-quality sand filter and the sand itself in the box is a massive value-add and a game-changer for water clarity.
• Tool-Free Assembly: The snap-together design makes setup intuitive and faster than traditional bolt-together frames.
• Complete Package: It truly is a “set.” You get the pool, pump, filter media, ground cloth, and patch kit—minimizing initial extra purchases.
• Durable Materials: The 3-ply liner and powder-coated, UV-protected steel are built to last multiple seasons with proper care.

What Could Be Improved (Cons)

• Significant Setup Time and Labor: While the frame goes together easily, the overall project—site leveling, assembly, filling—is a major 1-2 day undertaking requiring at least two people.
• High Ongoing Water & Chemical Costs: Filling and maintaining over 5,000 gallons of water has a notable utility and chemical cost, which should be factored into the budget.
• Not a Winter Pool: Like all above-ground pools of this type, it must be winterized and cannot be used in freezing temperatures, limiting its seasonal use in many climates.

Intex 26355EH Ultra XTR 18ft x 9ft x 52in Above Ground Swimming Pool Set with Sand Filter Pump and OptiFlow 50lb Premium Filter Sand vs. Competitors

How does this Intex set stack up against other popular options? Let’s compare it to a basic Intex frame pool and a higher-end steel-walled pool.

When to Choose This Product

Choose the Intex Ultra XTR if you want the closest experience to a permanent above-ground pool without the permanent installation. It’s ideal for those who plan to leave it up for multiple seasons, want minimal filter maintenance, and value a sturdy, safe-feeling structure. If your primary concern is whether the Intex Ultra XTR pool set is worth it from a durability and feature standpoint, this comparison shows it occupies a valuable middle ground.

When to Consider Alternatives

Consider a basic Intex Prism frame pool if you’re on a very tight budget, have a smaller space, or only want a pool for one season. Consider a traditional steel-walled pool if you want a truly permanent (10+ year) installation and are willing to invest significantly more in professional site prep and installation. For a full breakdown of Intex Ultra XTR vs alternatives, our dedicated comparison article has more details.

Who Should Buy Intex 26355EH Ultra XTR 18ft x 9ft x 52in Above Ground Swimming Pool Set with Sand Filter Pump and OptiFlow 50lb Premium Filter Sand?

Ideal For:

• Families with a Level Yard: Those with the space and a flat area who want a reliable, multi-season backyard fun center for kids and adults.
• Value-Seeking DIYers: Homeowners who appreciate a well-designed product that includes high-end features (sand filter) and is manageable to set up themselves.
• Those Tired of Flimsy Pools: If you’ve had a cheaper above-ground pool fail or feel unstable, the Ultra XTR’s robust construction is a worthy upgrade.

Not Recommended For:

• Those with Sloped or Uneven Yards: Proper installation requires a perfectly level site. Significant grading work can negate the value proposition.
• Extremely Budget-Conscious Shoppers: The initial cost is higher, and the ongoing water/chemical expense is substantial. A smaller, simpler pool may be a better fit.
• People Seeking a Permanent, Year-Round Pool: This is a seasonal product that must be winterized in cold climates.

Expert Tips for Maximum Value

Tip #1: Invest in a Proper Test Kit

Don’t rely on test strips alone. A liquid reagent test kit (like Taylor Technologies) is more accurate for pH and chlorine, saving you money on misapplied chemicals and keeping your water perfectly balanced.

Tip #2: Use a Solar Cover

A solar cover reduces water evaporation (saving on refills and chemicals), keeps heat in, and blocks debris. It’s one of the best accessory investments you can make.

Tip #3: Add a Skimmer Sock

Place a disposable skimmer sock or hairnet over the basket inside the pump’s skimmer. It catches fine dirt and pollen before they reach the sand filter, extending time between backwashes.

Tip #4: Level with Precision

Don’t eyeball it. Use a long 2×4 with a carpenter’s level on top to check your site in multiple directions. A pool that is off by even an inch can create dangerous pressure points.

Tip #5: Establish a Weekly Maintenance Routine

Pick one day a week for “pool day.” Test chemicals, backwash the filter, vacuum the floor, and skim the surface. Consistency is the key to clear water and a healthy pool.

Tip #6: Buy Chemicals in Bulk

Once you know your pool’s chemical consumption, buying chlorine tablets, shock, and pH adjusters in larger quantities from pool supply stores or online is far more cost-effective than small packages from big-box retailers. You can find good deals on bulk chemical kits alongside the pool.

Common Mistakes to Avoid

1. Mistake: Setting up on an unlevel surface. → Solution: Dedicate ample time to precise site preparation. It’s the most important step for safety and longevity.
2. Mistake: Running the pump for only a few hours a day. → Solution: Run the sand filter pump for 8-12 hours daily to ensure all the water is filtered multiple times, keeping it clean and algae-free.
3. Mistake: Forgetting to backwash the sand filter. → Solution: Set a weekly reminder to backwash for 2-3 minutes until the waste water runs clear, then rinse for 30 seconds.
4. Mistake: Adding chemicals directly to the skimmer or near the liner. → Solution: Always pre-dissolve chemicals in a bucket of pool water and pour them slowly into the deep end with the pump running to ensure even distribution and prevent liner damage.
5. Mistake: Draining the pool for winter without proper cleaning. → Solution: Balance the water, shock it, and clean the walls before lowering the water level. A dirty pool stored over winter will be stained and much harder to open.

Pricing & Where to Buy

The current price for the Intex 26355EH Ultra XTR set is around $1,074.98. While this is a significant investment, it’s crucial to view it as a complete kit. When you factor in the cost of a comparable sand filter system sold separately (which can be $300-$500), the value becomes clearer. You’re paying a premium for the convenience, engineered design, and included high-end filtration. Compared to the ongoing cost of a pool membership or the tens of thousands for an in-ground pool, it can pay for itself in a few summers for a family that uses it regularly.

Warranty & Support

Intex provides a 2-year limited warranty on this pool set, which is above average for the category and reflects their confidence in the materials. Registration is required online. Customer support is primarily handled via email and online forms. Based on user reports, they are generally responsive for part replacements under warranty, though the process can take some time. It’s wise to inspect all parts during assembly and report any missing or damaged components immediately.

Final Verdict

Summary of Key Findings

After a full season of testing, the Intex Ultra XTR impressed us with its stability, filtration performance, and thoughtful design. The sand filter is a standout, making maintenance easier than any cartridge system. The snap-together frame is both clever and incredibly sturdy. While the setup is a project, the resulting pool feels secure and high-quality.

Our Recommendation

So, is the Intex Ultra XTR pool set worth it? Our verdict is a resounding yes, for the right buyer. If you have a level yard, are willing to invest the initial effort in setup, and plan to use the pool for multiple seasons, it represents excellent value. It successfully bridges the gap between flimsy seasonal pools and permanent installations.

Bottom Line

The Intex Ultra XTR is a premium, feature-complete above-ground pool set that delivers a near-permanent feel with seasonal flexibility, making it a smart long-term investment for serious backyard fun.

Frequently Asked Questions

Is Intex 26355EH Ultra XTR 18ft x 9ft x 52in Above Ground Swimming Pool Set with Sand Filter Pump and OptiFlow 50lb Premium Filter Sand worth the money?

Yes, if you value durability and low-maintenance filtration. The included sand filter system alone adds significant value compared to buying a similar pool and filter separately. For a family that will use it for 3+ seasons, the cost-per-use becomes very reasonable, making the Intex Ultra XTR pool set worth it as a long-term backyard investment.

How does it compare to a basic Intex metal frame pool?

The Ultra XTR is in a different league. It has a more robust, tool-free frame, a vastly superior sand filter (basic pools use small cartridge filters), and includes the filter sand. The basic pool is a good one-season option, but the Ultra XTR is built and equipped for multi-year use with much clearer water and less daily hassle.

What’s the learning curve for beginners?

The assembly is beginner-friendly due to the snap-together design. The main learning curve involves understanding pool chemistry (testing and balancing pH/chlorine) and the sand filter’s backwash/rinse cycle. Both are well-explained in the manuals, and there are countless online resources. Plan for a learning period of about a week to get comfortable with the maintenance routine.

What accessories or additional items do I need?

Essential items not included: a pool water test kit, chlorine tablets or liquid chlorine, pH increaser/decreaser, pool shock, a manual vacuum head and hose, a telescopic pole, and a leaf skimmer. Highly recommended: a solar cover and a pool brush. You can find starter chemical kits here alongside the pool.

What warranty and customer support does it offer?

Intex offers a 2-year limited warranty on this set. You must register the product online after purchase. Support is available via their website. Keep your receipt and take pictures during unboxing to streamline any potential claims for missing or defective parts.

How long does setup take from start to finish?

For two reasonably handy people, plan for 4-8 hours total spread over 1-2 days. This includes final site leveling, frame assembly, liner placement, and starting to fill. The actual water filling time (often 12+ hours) is mostly unattended. Don’t rush the leveling step—it’s critical.

Where can I buy Intex 26355EH Ultra XTR 18ft x 9ft x 52in Above Ground Swimming Pool Set with Sand Filter Pump and OptiFlow 50lb Premium Filter Sand at the best price?

We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon typically offers reliable shipping, easy returns, and frequent price checks. Be wary of prices that seem too good to be true from unknown sellers, as warranty support may be difficult.
