What’s Included in the Box

Unboxing the INTEX 26379MZ is a significant event due to the sheer size of the box. The packaging is well-organized, with all components carefully packed to prevent damage during shipping. The box includes the pool liner, the complete Ultra XTR frame system (sidewalls, top rails, upright posts, T-joints), the 2,650 GPH sand filter pump, the saltwater system, the Type B ground cloth, the Type B pool cover, the A-frame ladder, the deluxe maintenance kit, and a volleyball set. The first impression is that of high quality. The galvanized steel parts are heavy and feel substantial. The liner feels thick and robust, not flimsy like some budget pools. The included instructions are clear, which is a plus for such a complex setup. Based on our unboxing, an Intex Ultra XTR review honest opinion is that the build quality looks promising right out of the gate.

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

Setting up and using this pool correctly is critical for safety and longevity. Our Intex Ultra XTR pool review is incomplete without a thorough guide.

Step 1: Initial Setup and Installation

Choose a perfectly level spot in your yard. Remove any rocks, roots, or debris. Lay down the ground cloth. The Ultra XTR frame uses a snap-together system. Connect the top rails and upright posts using the precision lock. Intex says it takes 90 minutes, but realistically, you need two people and about 2 to 3 hours for the base frame. Do not tighten any bolts until the entire frame is assembled. This allows for adjustments.

Step 2: First-Time User Guide

Once the frame is up, drape the liner over the top and secure it. Start adding a few inches of water to smooth out the liner. Continue filling. Connect the sand filter pump. You need to add sand to the filter (not included in the box). Prime the pump according to the manual.

Step 3: Core Functions and Daily Use

Run the filter pump for at least 8 to 12 hours a day. For the saltwater system, add the recommended amount of pool salt. The system will then generate chlorine naturally. Use the included test kit to monitor chlorine and pH levels weekly.

Step 4: Advanced Techniques

To maximize the clarity of your water, run the filter pump overnight. Use the pool cover when the pool is not in use to keep debris out and reduce chlorine consumption. A winter cover is included, which is excellent for off-season protection.

Step 5: Maintenance and Care

Backwash the sand filter once a week to clean it. Vacuum the pool floor at least once a week using the included vacuum head. Check the liner for any small punctures. The is Intex Ultra XTR worth buying depends heavily on maintenance. Store the ladder and volleyball set indoors during winter.

Step 6: Troubleshooting Common Issues

If the water is cloudy, check the filter pressure. You might need to backwash. If the pump is not drawing water, ensure the filter basket is not clogged. If the saltwater system shows a low salt error, add more pool salt.

Performance & Real-World Testing

Testing Methodology

We set up this pool in a suburban backyard with a slightly sloping lawn. We tested it over three months of active summer use, including daily swimming, weekly maintenance, and a few storm events. Our goal was to verify every manufacturer claim in real-world conditions.

Performance Metrics

The filtration system is excellent. The 2,650 GPH sand filter cleared a green pool in under 48 hours. The rectangular shape is fantastic for lap swimming and playing games. The Ultra XTR frame feels rock-solid once filled.

Real-World Scenarios

We tested the pool’s durability by having a group of teenagers play volleyball in it. The frame didn’t wobble. The liner resisted a dropped metal pole without damage. The saltwater system produced fantastic water quality with very low maintenance. We were impressed with the rust-resistant powder coating, which showed no signs of corrosion even after rain.

Claims vs. Reality

Intex claims a 90-minute assembly time. We found it took closer to 3 hours total with two people. However, the assembly process is straightforward. The “puncture resistant” claim holds up. In our testing, this is the most durable liner we have tested. An honest Intex Ultra XTR review honest opinion is that the performance matches the marketing for durability and filtration.

Pros and Cons

What We Loved (Pros)

• Exceptional Frame Stability: The Ultra XTR locking system creates an incredibly rigid and wobbly-free structure, even at full 52-inch depth.
• Superior Liner Durability: The 3-ply SuperTough material withstands sharp objects and heavy use much better than standard liners.
• Complete Package Value: You get a premium sand filter, saltwater system, cover, maintenance kit, and volleyball set in one box, saving you hundreds of dollars compared to buying separately.
• Excellent Water Quality: The combination of the sand filter and saltwater system produces crystal-clear, soft water that feels great on the skin.
• Rust Resistance: The powder coating on the steel frame is top-notch. After a whole season, we saw zero rust spotting.

What Could Be Improved (Cons)

• Assembly Requires Two People: While the snap-together frame is innovative, the sheer size and weight of the components make it a two-person job.
• Initial Cost is High: This is a premium above-ground pool, and the price reflects that. It is a significant investment.
• Level Ground is Critical: Setting this up on a completely level surface is non-negotiable. Any slope can cause structural stress.

Who Should Buy INTEX 26379MZ 36ft x 18ft x 52in Ultra XTR Deluxe Rectangular Above Ground Swimming Pool Set?

Ideal For:

• Large Families: With a 36ft x 18ft size, this pool easily accommodates multiple children and adults simultaneously. It is perfect for swimming laps and family games.
• Serious Swimmers: The rectangular shape is ideal for swimming lengths, making it a great choice for exercise.
• Long-Term Pool Owners: The high build quality and rust-resistant frame are designed to last for years, making it a sound long-term investment.

Not Recommended For:

• People with Small or Sloped Yards: This pool requires a large, perfectly level patch of land. If your yard is sloped, you need to consider a different product or significant ground leveling.
• Budget-Conscious Buyers: This is a premium product. If you need the cheapest option to get wet, look at simpler, smaller pools. Consider if an Intex Ultra XTR review and rating suggests it fits your budget.

Expert Tips for Maximum Value

Tip #1: Level Your Ground Perfectly

Spend extra time ensuring the ground is level to within 1 inch. Use a long level board across the entire area. This prevents frame stress and liner damage.

Tip #2: Use a Solar Cover

While the pool cover included is great for winter, use a solar cover during the day. It heats the water naturally and reduces chlorine loss from UV rays. This saves you energy and chemical costs.

Tip #3: Invest in a Pool Heater

For maximum enjoyment in cooler climates, consider a heat pump or gas heater. The 52-inch depth holds heat well, but a heater can extend your swimming season by months. Check the Intex Ultra XTR review verdict on compatibility.

Tip #4: Automate Your Chemical Routine

Use a floating chlorine dispenser for additional chlorine if needed, or use a saltwater chlorinator tablet floater for consistent output.

Tip #5: Backwash the Filter Regularly

Set a schedule to backwash your sand filter every week. This keeps water flow high and filtration efficient.

Tip #6: Store Components Indoors

When not in use for the winter, store the ladder, pump, and saltwater system in a dry shed. This dramatically extends their lifespan.

Tip #7: Use a Winter Cover Correctly

Use the included winter cover during the off-season. Use a cover pump to prevent water from collecting on top, which can cause the cover to collapse.

Common Mistakes to Avoid

1. Mistake: Assembling the frame on uneven ground. Solution: Use a long level to check the entire pool area before assembly.
2. Mistake: Tightening all frame bolts immediately. Solution: Leave bolts loose until the full frame is assembled, then tighten evenly.
3. Mistake: Filling the pool without smoothing the liner. Solution: Add only a few inches of water, then pull and smooth the liner to eliminate wrinkles.
4. Mistake: Not adding sand to the filter. Solution: Follow the filter manual carefully and add the recommended type and amount of sand before starting.
5. Mistake: Ignoring the saltwater system’s low salt alerts. Solution: Test your salt levels regularly and add salt as needed for the system to generate chlorine.

Pricing & Where to Buy

The current price is 2,499.99 USD. This is a premium price point, but it represents significant value when you consider that it includes a high-quality sand filter pump (which alone can cost $300+), a saltwater system (another $200-$400), plus the maintenance kit, cover, ground cloth, and volleyball set. The frame and liner are top-tier. In terms of value per gallon of water and feature set, this is very competitive against comparable in-ground or expensive metal frame pools.

Warranty & Support

The Intex Ultra XTR pool comes with a 2-year limited warranty on the frame and liner. Intex’s customer service is generally responsive, though large claims can take time. The return policy depends on the seller, but Amazon typically offers a 30-day return window.

Frequently Asked Questions

Is INTEX 26379MZ 36ft x 18ft x 52in Ultra XTR Deluxe Rectangular Above Ground Swimming Pool Set worth the money?

Yes. When you calculate the cost of buying a high-quality sand filter, saltwater system, cover, maintenance kit, and ladder separately, the total package price is very competitive. The premium frame and liner justify the cost for long-term use. For large families or serious swimmers, the value is excellent.

How does it compare to an in-ground pool?

An in-ground pool is significantly more expensive (typically $30k+) and requires permanent excavation and permits. The Intex Ultra XTR offers a similar swimming experience regarding size and water quality but at a fraction of the cost and with the ability to disassemble and store it. The main difference is the above-ground appearance.

What’s the learning curve for beginners?

For basic use, the learning curve is low. The instructions are clear, and the chemical maintenance is straightforward with the saltwater system. The main challenge is the initial assembly, which can take a few hours, but it is not technically difficult. In our Intex Ultra XTR review honest opinion, beginners can manage it with patience.

What accessories or additional items do I need?

You will need pool salt for the saltwater system and sand for the filter. A solar cover is highly recommended to heat the water. A pool testing kit for chlorine and pH is essential. You can find compatible accessories online.

What warranty and customer support does it offer?

Intex offers a 2-year limited warranty on the frame and liner. Customer support can be reached through their website. Response times vary but are generally acceptable for routine questions. Complex warranty claims can require documentation.

Where can I buy INTEX 26379MZ at the best price?

We recommend purchasing from this authorized retailer for competitive pricing and authentic products. Amazon often has the best prices and fastest shipping for this large item.

How long does the frame last before rusting?

With proper care and storage, the galvanized steel frame with the powder coating can last 5-8 years or more. The key is to store the pool dry during winter and ensure the ground is level to minimize stress. Our Intex Ultra XTR review and rating is positive on longevity.

Can I use a regular chlorine system instead of the saltwater system?

Yes, you can bypass the saltwater system and use standard chlorine tablets or liquid chlorine. However, the saltwater system is a significant benefit for reducing chemical handling and providing softer water. Many buyers choose this model specifically for the saltwater system.
