What Is the SunSwell Above Ground Pool?

The SunSwell above ground pool is a rectangular framed swimming pool designed for residential backyard use. It measures 18 feet long by 9 feet wide by 47 inches deep (inner dimensions), with overall frame dimensions extending to 20 feet by 11 feet 3.4 inches. Manufactured by SunSwell, this pool set targets families who want a spacious swimming area without the commitment of an in-ground pool. It’s categorized as a “framed swimming pool,” meaning it relies on a metal frame for structural support rather than inflatable rings or simple blow-up walls.

The pool’s rectangular shape sets it apart from the more common round above-ground pools, offering a more traditional “swimming lane” feel. The gray color and 3-ply PVC construction aim for a sleek look that blends into a modern backyard. SunSwell markets this pool as a solution for creating “peaceful outdoor spaces,” emphasizing ease of assembly and durability.

This review will focus on the product’s specifications, user feedback (based on the 3.8 out of 5 stars from 88 ratings), and how it compares to similar models from other brands. Whether you’re a first-time above-ground pool owner or upgrading from a smaller kiddie pool, this article will give you the honest overview you need.

Key Features & Specifications

The SunSwell 18×9 rectangular pool comes with a set of features that combine convenience with structural integrity. Below is a breakdown of the most important aspects.

Durable Construction Materials

• Puncture-Resistant 3-Ply PVC Liner: The pool liner is made from three layers of PVC, which the manufacturer claims resists everyday wear and tear. Repair patches are included for minor punctures.
• Material Behavior Note: SunSwell states that the liner becomes stiff in winter (making installation or folding harder in cold weather) and softer in summer. This is typical of PVC and not a defect.
• Frame Material: The frame uses high-quality galvanized steel combined with a precision-engineered locking system to improve overall stability.

Dimensions and Capacity

Measurement	Value
Overall dimensions with frame	20 ft x 11 ft 3.4 in x 47.24 in
Inner dimensions (water surface)	17 ft 8.6 in x 8 ft 10.3 in x 47.24 in
Water capacity	3,848 gallons

Included Accessories

• Filter Pump: Comes with a control valve for filtering, draining, and adding water. The pump is described as leak-proof.
• Movable Ladder: Attached to the pool for safe entry and exit; can be repositioned as needed.
• Pool Cover: Included to keep debris out when the pool is not in use.
• Repair Patches: For fixing accidental punctures.

Assembly and Locking System

SunSwell promotes an “Easy Lock System” where the main body of the pool assembles without hardware. The manufacturer states that the pool can be ready for water in 60 minutes. Note that this time is for the frame assembly and liner setup; filling the 3,848-gallon pool will take considerably longer depending on water pressure.

What’s Included in the Box

According to the product details, the SunSwell above ground pool set arrives with the following components:

• Pool liner (3-ply PVC, rectangular shape)
• Galvanized steel frame tubes and connectors
• Filter pump (with hoses and control valve)
• Pool cover
• Movable ladder
• Repair patches
• Installation manual

The package is comprehensive, meaning you won’t need to purchase a separate pump or ladder for basic operation. However, you will need to supply your own water source, a level ground area, and potentially a ground cloth or tarp (not included) to protect the liner from rocks and roots.

How to Use the SunSwell 18×9 Pool

Setting up and maintaining an above ground pool requires some planning. Below are step-by-step guidelines based on the manufacturer’s instructions and typical best practices. (Note: We have not personally tested this unit; the following is based on product literature and general knowledge of similar framed pools.)

Setup

1. Select a Level Location: Choose a flat, clear area free of sharp objects. The final footprint (including frame) is about 20×11 feet, so ensure adequate space.
2. Prepare the Ground: Many users recommend using a ground cloth or sand base to protect the liner. The manufacturer does not specify a base, but it’s a common practice.
3. Assemble the Frame: Follow the manual to connect the galvanized steel tubes using the Easy Lock System. No tools are required for the main frame.
4. Install the Liner: Drape the 3-ply PVC liner inside the frame and smooth out wrinkles. Attach the liner to the top rail.
5. Add Water: Begin filling the pool. The manufacturer states the pool can be ready for water in about 60 minutes of assembly time. Filling will take several hours depending on hose flow.
6. Set Up the Pump: Attach the filter pump according to instructions, then start the pump once water level is above the intake.
7. Install Ladder: Position the movable ladder at your preferred entry point.

Operation

After filling, the filter pump should run daily to keep water clear. The control valve allows you to switch between filtering, draining, and infusing (to add fresh water). SunSwell describes the pump as leak-proof, which should reduce water loss from connections.

Maintenance

• Chemical Balance: Like any pool, you must regularly test and adjust pH, chlorine, and alkalinity. The manufacturer does not supply chemicals.
• Cleaning: Skim leaves and debris daily. Vacuum the pool floor periodically. The included cover helps reduce debris.
• Winter Storage: Because the PVC stiffens in cold weather, the manufacturer recommends draining and disassembling before freezing temperatures arrive. Folding the liner when stiff may lead to cracks; wait for warmer days or carefully handle.

Troubleshooting Common Issues

• Liner Wrinkles: If wrinkles appear after filling, they may be cosmetic. Avoid dragging heavy objects across the liner.
• Pump Not Priming: Ensure water level is high enough and hoses are properly connected. Check for air leaks.
• Slow Leak: Use the included repair patches for small punctures. For larger tears, a patch kit from a pool supply store may be needed.

Performance & User Experience

SunSwell positions this pool as a “super tough” rectangular option. Based on the product description, the key performance claims are:

• Puncture resistance from the 3-ply PVC.
• Stable structure thanks to galvanized steel frame and locking system.
• Quick assembly in 60 minutes.
• Effective water filtration from the included pump.

User reviews on Amazon (3.8 out of 5 stars from 88 ratings) suggest generally positive experiences, but with some caveats. Common praise includes the spacious rectangle shape, solid frame, and relatively straightforward assembly. Some users noted that the 60-minute assembly time is optimistic, especially for first-time builders, and that leveling the ground is critical to avoid stress on the frame.

The filter pump is described as adequate for a pool of this size, though some buyers recommended upgrading to a larger pump for heavy usage. The movable ladder received mixed feedback—some found it sturdy, others reported it feeling less secure over time. As with any above ground pool, longevity depends on proper ground preparation, chemical maintenance, and winter storage.

Because the liner changes stiffness with temperature, owners in colder climates should plan to disassemble in autumn. The product’s material note is an honest disclosure, but it’s worth factoring into your decision if you live in an area with harsh winters.

Pros and Cons

Weighing the benefits and drawbacks helps determine if this pool fits your needs.

Pros

• Rectangular shape: Provides a more traditional swimming experience than round pools, ideal for laps or games.
• Sturdy frame: Galvanized steel with locking system offers good stability.
• Easy assembly: No tools needed for the main frame; clear instructions help.
• Complete set: Includes pump, ladder, cover, and repair patches—no extra initial purchases.
• Puncture-resistant liner: 3-ply PVC is tougher than single-layer inflatable pools.

Cons

• Temperature sensitivity: Liner becomes stiff in cold weather, complicating winter storage.
• 60-minute assembly claim may be unrealistic: Ground prep and careful liner placement take additional time.
• Filter pump may be underpowered: Some users recommend a larger pump for heavy use.
• Ladder quality concerns: Mixed reviews on long-term stability.
• No ground cloth included: You’ll need to purchase additional protection.

Comparison With Alternatives

Two main competitors in the rectangular above ground pool segment are Intex (Ultra Frame or Prism Frame series) and Bestway (Steel Pro or Power Steel series). Below is a feature comparison based on publicly available specs.

Feature	SunSwell 18×9	Intex Ultra Frame 18x9x52	Bestway Power Steel 18x9x48
Shape	Rectangular	Rectangular	Rectangular
Water Depth	47 in	52 in	48 in
Liner Material	3-ply PVC	3-ply PVC	3-ply PVC
Frame Material	Galvanized steel	Galvanized steel	Galvanized steel
Included Pump	Yes (spec not stated)	Krystal Clear (110-1200 GPH)	Flowclear (530 GPH or higher)
Ladder	Movable included	Removable A-frame	Removable A-frame
Cover	Included	Included	Included
Assembly Claim	60 min	~180 min	~120 min

Note: SunSwell’s assembly claim is shorter, but users of Intex and Bestway often report longer actual times. The Intex model offers a deeper 52-inch depth, which may be preferred by adults, while Bestway’s pump specifications are often published in detail. SunSwell’s included pump capacity is not specified in the product data, making direct filtration comparison difficult.

Who Should Buy This Product?

Ideal For:

• Families with moderate-sized backyards wanting a rectangular pool that fits into a rectangular deck or landscaping.
• First-time above ground pool buyers who value a complete kit (pump, ladder, cover) and a relatively quick setup.
• Users in mild climates where winter storage is not a major issue, or those willing to disassemble each fall.
• People who want a pool for casual swimming, cooling off, and basic water games rather than serious lap training.

Not Ideal For:

• Those living in regions with long, harsh winters, unless they are prepared for careful winterization and storage.
• Swimmers looking for deep water (over 48 inches) for diving or aggressive lap training.
• Buyers who want a heavy-duty pump from a well-known brand—check pump specs or plan to replace.
• Anyone constrained by ground leveling challenges; this pool is less forgiving on uneven terrain.

Expert Tips

1. Always level the ground thoroughly: Even a slight slope can cause frame stress and eventually lead to liner tears. Use a long level and consider a ground cloth or tarp underneath.
2. Allow extra time for assembly: While the manufacturer says 60 minutes, a careful first-time setup with liner smoothing and pump connection could take 2–4 hours. Plan accordingly.
3. Consider a larger filter pump: If the included pump seems underpowered, upgrading to a 1500 GPH or larger pump (compatible with 1.5-inch hoses) can improve water clarity, especially on hot days.
4. Maintain chemical balance from day one: Cloudy water and algae are common issues when new pool owners neglect testing. Invest in a test kit and basic pool chemicals.
5. Winter storage strategy: If you live in a freeze zone, drain and disassemble the pool before night temperatures drop below 40°F. Store the liner in a warm place to keep it flexible.

Common Mistakes

1. Not clearing debris from the ground: Rocks or roots under the liner cause punctures quickly. Spend time clearing and smoothing the area.
2. Over-tightening frame connections: The Easy Lock system should be snug, not forced. Overtightening can crack components.
3. Neglecting to use the cover: Without it, leaves and dirt accumulate, straining the filter and requiring more chemicals.
4. Running the pump dry: Never run the filter pump when water level is below the intake. This can damage the pump motor.
5. Ignoring material temperature warnings: Attempting to fold the liner when it’s stiff in winter can cause permanent creases or cracks. Handle with care.
6. Forgetting to check local regulations: Some municipalities require fences or safety inspections for pools over a certain capacity. Confirm before installation.

Final Verdict

After analyzing the SunSwell above ground pool’s features, specifications, and user feedback, we find it to be a solid option for families seeking a rectangular pool without a high upfront cost. The puncture-resistant 3-ply PVC liner, galvanized steel frame, and included accessories make it a convenient package. The assembly system is genuinely simpler than many competitors, though the 60-minute claim should be taken as a best-case scenario.

However, the pool’s winter stiffness, uncertified pump performance, and mixed ladder reviews are important trade-offs. For users in moderate climates who can dedicate a few hours to setup and seasonal care, this SunSwell pool offers a spacious, attractive swimming area. Those in cold regions or wanting a premium filter pump might look to Intex or Bestway alternatives instead.

Ultimately, the SunSwell 18×9 pool review verdict is that it’s worth considering if you prioritize rectangular shape, easy assembly, and a complete kit. It’s not the most heavy-duty option, but for the intended use—backyard family fun—it should serve well with proper maintenance.

Frequently Asked Questions (FAQ)

1. How long does it really take to set up the SunSwell 18×9 pool?
   While the manufacturer claims 60 minutes, users report 2–4 hours for the full process including ground preparation and pump installation.
2. Can I leave the pool up all year?
   It is not recommended for cold climates. The PVC stiffens in winter, making the liner brittle. Drain and store indoors below freezing temperatures.
3. What kind of ground base do I need?
   You should have level, clear ground. Many users place a tarp or ground cloth underneath to protect the liner. Never install directly on rocks or roots.
4. Does the filter pump produce enough flow for this size pool?
   The pump is rated for the pool’s capacity, but for heavy usage or hot weather, some users upgrade to a higher-GPH model. Check specific pump specs on the product page.
5. Is the ladder safe for children?
   The ladder is movable and designed for general entry/exit. Children should always be supervised. Consider placing a lock on the ladder when not in use.
6. Can I use the pool with salt water?
   The manufacturer does not specify saltwater compatibility. Standard chlorine, bromine, or hydrogen peroxide sanitizers are recommended.
7. What if the liner gets a tear?
   Repair patches are included for small punctures. For larger holes, you may need a PVC patch kit or pool liner sealant.
8. How often should I run the filter pump?
   Typically, 6–8 hours per day in hot weather, and less when the pool is not used. Always follow the pump manufacturer’s guidelines.
