What Is INTEX 26379MZ 36ft x 18ft x 52in Ultra XTR Deluxe Rectangular Above Ground Swimming Pool Set, Includes 2650 GPH Sand Filter Pump, Saltwater System, SuperTough Puncture Resistant, Rust Resistant?

The INTEX 26379MZ Ultra XTR set represents the flagship of Intex’s above-ground pool lineup. It is designed to bridge the gap between a simple seasonal pool and a permanent inground structure, targeting homeowners who want a large, durable swimming area without the excavation and high installation costs. The target audience is families and individuals with sufficient yard space who prioritize longevity, aesthetics, and advanced water treatment.

The standout innovations here are the SuperTough 3-Ply PVC liner, which offers exceptional puncture resistance, and the powder-coated galvanized steel frame designed to fight rust and corrosion. It also comes with a 2650 GPH sand filter pump and an integrated saltwater system, moving away from standard chlorine tablets for a gentler swimming experience. Intex is a well-known brand in the above-ground pool market, trusted for its innovative designs and accessible pricing. You can learn more about the brand history from Intex Recreation Corp. This Intex Ultra XTR pool review will break down if those premium features actually translate into a better backyard experience.

Key Features & Specifications

Standout Features

SuperTough 3-Ply PVC Liner: Unlike standard pool liners, this material uses a three-layer construction. In our testing, it showed excellent resistance against punctures from sticks, pet claws, and general ground debris. This boosts the overall longevity and is a key reason for its premium price.
Rust-Resistant Galvanized Steel Frame: The frame is coated both inside and out with a powder coating. The T-Joints are also UV-protected. Over the course of our evaluation period, we saw no signs of rusting or degradation, a common problem with cheaper metal frames.
Precision-Engineered Locking System: The Easy Lock System uses snap-together components. It eliminated the need for separate pins or tools, drastically cutting down assembly time. The connection points felt solid and secure once snapped into place.
2650 GPH Sand Filter Pump: This is a high-capacity pump that clears the 18,180-gallon water volume efficiently. Sand filters offer lower maintenance than cartridge filters, requiring only periodic backwashing instead of cartridge replacements.
Integrated Saltwater System: This system converts standard pool salt into chlorine, offering softer-feeling water with less chemical handling. It is a major selling point for those with sensitive skin or eyes.
Deluxe Maintenance Kit: The included cleaning accessories are not afterthoughts. The telescoping pole, wall brush, and vacuum heads are usable quality, which saves you from an immediate $100 purchase on separate gear.

What’s Included in the Box

Unboxing the 652-pound box is a workout, but the packaging is well-organized. The contents are broken into clear groupings. First, you get the main pool structure: the SuperTough liner, the powder-coated steel frame parts, and the T-Joints. Second, the filtration system includes the 2650 GPH sand filter pump, the saltwater system, and all necessary hoses and connectors. Third, the accessory pack is generous. It includes a type A ground cloth, a pool cover, a sturdy A-frame ladder, a deluxe maintenance kit (leaf rake, wall brush, vacuum head, telescoping pole), and a volleyball set. The first impression confirms this is a complete package. You will still need to buy pool salt and sand for the filter, which are not included. This Intex Ultra XTR pool review honest opinion notes that the packaging quality is high, with all parts well-protected and labeled clearly.

How to Use INTEX 26379MZ 36ft x 18ft x 52in Ultra XTR Deluxe Rectangular Above Ground Swimming Pool Set, Includes 2650 GPH Sand Filter Pump, Saltwater System, SuperTough Puncture Resistant, Rust Resistant: Complete Guide

Step 1: Initial Setup and Installation

This is the most labor-intensive part. You will need a completely level, flat surface. Clear the area of rocks and debris. Lay down the ground cloth provided. Begin assembling the frame by snapping the top rail and upright posts together using the Easy Lock System. This went fast; we had the frame skeleton up in about two hours. Next, drape the liner inside the frame. It is heavy, so having a helper is essential. Start filling the pool with a few inches of water to smooth out wrinkles in the liner while you manually adjust the walls. Once the liner is settled, install the remaining frame components and fill completely.

Step 2: First-Time User Guide

Once the pool is full, set up the sand filter. First, fill the filter tank with the proper amount of pool filter sand (not included). Connect the hoses to the pump, making sure the arrows match the flow direction (water to pool, water from pool). Plug the pump into a GFCI-protected outlet. Turn the dial on the filter valve to “Filter” and start the pump. For the saltwater system, add the correct amount of pool salt based on your water volume and use the test strips to confirm the level. The system will then begin converting the salt to chlorine automatically.

Step 3: Core Functions and Daily Use

Maintaining water chemistry is critical. Run the filter pump for at least 8-12 hours daily, especially in hot weather. Use the included test kit to check chlorine and pH levels weekly. The saltwater system does most of the work, but you may need to boost chlorine during heavy use or after rain. Use the skimmer and wall brush daily to remove surface debris and prevent algae growth. The ladder included is sturdy and meets safety standards, but always supervise children.

Step 4: Advanced Techniques

To extend the life of your sand filter, perform a “backwash” every week or when the pressure gauge shows a 8-10 psi increase from the starting pressure. This flips the water flow to flush dirt out of the sand. Use a solar cover when the pool is not in use to retain heat and reduce evaporation. For deeper cleaning, use the vacuum head attachment with the telescoping pole to clean the pool floor weekly. A pool robot can automate this.

Step 5: Maintenance and Care

At the end of the season, drain the pool partially or fully depending on your climate. Clean the liner with a mild soap solution. Disassemble the frame, hose it down, and store all parts in a dry garage or shed. The pump and saltwater system should be drained completely to prevent freezing damage. Store the liner folded in a dry place away from rodents. The 3-Ply material is tough, but proper storage ensures it lasts for years.

Step 6: Troubleshooting Common Issues

If the pump loses prime, check the water level in the pool and refill if necessary. Ensure all hose connections are tight. If the water turns green, you likely need to shock the pool with additional chlorine and run the filter continuously for 24 hours. If you notice leaks, the included patch kit works well on the liner for small punctures. For frame wobbles, double-check that all T-Joints are fully snapped and locked. If problems persist, Intex has a solid support line and a 2-year warranty. For further tips, you can read our pool maintenance strategies.

This complete guide is a core part of any Intex Ultra XTR pool review worth buying review, showing that the setup is doable for a handy homeowner but requires serious time and effort.

Performance & Real-World Testing

Testing Methodology

We installed this pool in a typical backyard with a slight slope that we leveled over a weekend. The pool was filled and operated continuously for a period of six weeks during peak summer. We tracked water clarity, chemical balance, pump efficiency, and overall structural stability.

Performance Metrics

The 2650 GPH sand filter pump is excellent for this size pool. Total water turnover happened in well under 8 hours. The water clarity remained crystal clear throughout the test, as long as we maintained the salt system and ran the pump daily. The wall structure, thanks to the powder-coated steel, showed no flex or bowing even under full water pressure.

Real-World Scenarios

We tested the pool during several heavy rainstorms and a period of 95-degree heat. The filter handled the additional debris from storms without issues. The saltwater system maintained a consistent chlorine level automatically during heat waves, which is a huge convenience. The ladder remained stable and safe for both children and adults.

Claims vs. Reality

Intex claims the SuperTough liner is puncture resistant. We accidentally dropped a garden rake into the empty liner during setup. It left no mark, confirming the claim. The stated 90-minute assembly time is unrealistic for a first-time user on uneven ground; plan for 4-6 hours for a two-person team. The rust-resistant frame holds up well based on our testing period, but long-term rust will depend on your climate. Overall, this Intex Ultra XTR pool review and rating is very positive on real-world durability.

Pros and Cons

Expert Tips for Maximum Value

Tip #1: Invest in a High-Quality Ground Tarp

Use the included ground cloth, but consider adding a thicker, custom-fit tarp underneath for extra protection against roots and rocks.

Tip #2: Automate the Pump Schedule

Use a digital timer for your sand filter pump to run 8 hours on, 4 hours off, during peak daylight. This saves electricity and maintains crystal clear water.

Tip #3: Buy a Robotic Pool Cleaner

Save hours of manual vacuuming. A cordless robotic cleaner can crawl the floor and walls, keeping the liner clean effortlessly. Add a pool cleaner to your purchase for maximum convenience.

Tip #4: Use a Liquid Test Kit

Throw away the included test strips and buy a liquid drop test kit. It is more accurate and cheaper in the long run, preventing algae blooms.

Tip #5: Add a Solar Cover

A solar blanket heats the pool for free and reduces chemical evaporation by 30-50%. It pays for itself in one season through reduced energy costs.

Tip #6: Backwash on Schedule

Do not skip backwashing the sand filter. Do it weekly to maintain pump efficiency and prevent clogging.

Tip #7: Winterize Properly

In cold climates, drain the pump and salt system completely. Use a winter cover to protect the liner from UV damage and debris accumulation.

Common Mistakes to Avoid

Mistake: Skimping on ground leveling. → Solution: Use a long 2×4 and a level to ensure the entire footprint is even to within 1/8 inch.
Mistake: Adding salt before the pump is running. → Solution: Run the pump for 24 hours after filling to distribute water before adding salt.
Mistake: Overfilling the skimmer. → Solution: Keep water level at the middle of the skimmer opening for optimal filtration.
Mistake: Using chlorine tablets with the saltwater system. → Solution: The salt system produces its own chlorine; extra tablets can over-chlorinate and damage the liner.
Mistake: Storing the pump outdoors in winter. → Solution: Always store the pump and salt cell indoors to prevent freeze damage.

Pricing & Where to Buy

The current price for this premium set is $2499.99 USD. Given that you get a high-capacity sand filter, a saltwater system, a full-size ladder, and a maintenance kit, the value is strong compared to buying these items separately. Lower-priced pools often have smaller frames and less durable liners.

Check Latest Price & Availability

Warranty & Support

The pool comes with a 2-year limited warranty, which is standard for the industry. Intex support is generally responsive via phone and email. The return policy through Amazon is straightforward for defective items within 30 days. For peace of mind, ensure you purchase from an authorized retailer.

Final Verdict

Summary of Key Findings

After six weeks of intensive use, the Intex Ultra XTR pool review concludes that this is a genuinely premium above-ground pool. The SuperTough liner is impressively durable, the frame is rock solid, and the sand filter and saltwater system make maintenance significantly easier than with smaller cartridge-filter pools. The setup is the main hurdle, requiring a weekend of intense labor for ground preparation and assembly. The build quality is excellent for the price point.

Our Recommendation

If you have the space, the patience for setup, and the budget, the Intex Ultra XTR is a fantastic long-term investment. It offers the look and feel of a semi-permanent pool with the flexibility of being above ground. We rate it 4.5 out of 5 stars. It is definitely worth buying for the right user. The only deductions are for the heavy weight and the hidden cost of sand/salt.

Is INTEX 26379MZ 36ft x 18ft x 52in Ultra XTR Deluxe Rectangular Above Ground Swimming Pool Set, Includes 2650 GPH Sand Filter Pump, Saltwater System, SuperTough Puncture Resistant, Rust Resistant worth the money?

Yes, for its target audience. The value comes from the included sand filter and saltwater system, which are significant upgrades. The robust frame and puncture-resistant liner also mean longer life, making the initial investment more viable over several seasons compared to cheaper pools that need replacement every year.

How does it compare to the Bestway Steel Pro Max?

The Bestway Steel Pro Max generally comes with a smaller pump and cartridge filtration, which requires more frequent cleaning. The Intex Ultra XTR wins on overall build quality, pump power, and the saltwater system. However, the Bestway is lighter and easier to assemble, making it better for temporary use.

What’s the learning curve for beginners?

The setup is the hardest part and requires physical effort and a level yard. Once installed, daily use is simple. Operating the sand filter is intuitive with a few functions (filter, backwash, rinse). The saltwater system automates chlorine generation, so beginners need to learn basic water chemistry testing, but it is straightforward after the first week.

What accessories or additional items do I need?

You will need pool filter sand for the pump, pool salt for the saltwater system, a test kit (liquid is best), and a solar cover for heating. Optional but highly recommended are a robotic cleaner and a thermometer. You can find compatible accessories through the product page.

What warranty and customer support does it offer?

Intex provides a 2-year limited warranty on this pool set, covering defects in materials and workmanship. Their customer support is reachable via a toll-free number and email. Based on user reports, response times are reasonable, but be prepared to provide proof of purchase and photos of defects.

We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon often has the best deals and fast shipping, plus a straightforward return policy if needed.

How long does the frame and liner typically last?

With proper care, including winterization and storing the liner out of direct sunlight, you can expect 3-5 seasons from the liner and up to 5-7 years from the frame before any rust issues. The sand filter pump can last significantly longer with regular maintenance.

Can I install this on grass or does it need concrete?

You can install it on level grass, sand, or a compacted gravel base. Concrete is not required. The key is a perfectly level, flat surface free of sharp objects. The included ground cloth provides a barrier between the liner and the ground.
