More Details on Our Top Picks
Intex Solar Pool Cover for 18ft Round Above Ground Pools
This solar cover excels in simplicity and effectiveness for 18-foot round pools, providing excellent insulation and debris protection while reducing water evaporation by 95%. Compared to the larger VINGLI or BigXwell covers, it offers a straightforward, plug-and-play solution tailored specifically to this pool size, making installation and removal hassle-free. The main tradeoff is its limited size compatibility, which means it doesn’t adapt to irregular or different-sized pools, and it depends entirely on sunlight for heating. Nonetheless, its affordability and durability make it a reliable choice for owners seeking a dedicated, no-fuss solar cover for a standard above-ground pool.
Pros:- Simple to install and remove, saving time and effort
- Effective at reducing water evaporation and retaining heat
- Protects against debris and leaves, keeping pool cleaner
- Affordable price point with durable polyethylene material
Cons:- Limited to 18-foot round pools, not versatile for other shapes or sizes
- Dependent on sunlight for heating, less effective on cloudy days
- May need replacement after prolonged exposure or heavy use
Best for: Homeowners with 18-foot round above-ground pools seeking an easy-to-use, effective solar cover.
Not ideal for: Buyers with irregularly shaped or larger pools, since this cover only fits 18-foot round pools well.
- Pool Size:18-foot round
- Material:Polyethylene
- Purpose:Solar heating, debris protection
- Compatibility:Intex above ground pools
Our verdict“This cover makes the most sense for owners of 18-foot round pools prioritizing ease of use and reliable heat retention.”
Intex 28014E Solar Pool Cover for 16ft Round Pools
The Intex 28014E offers a solid balance between affordability and functionality for 16-foot above ground pools. Its straightforward design makes it easy to lay on the water surface, providing significant insulation and evaporation reduction comparable to pricier options like the BigXwell cover. Compared with larger covers, it’s optimized for a specific size, which can be a limitation if your pool dimensions differ. Lacking a manufacturer warranty adds some risk, especially over long-term use. Still, its affordability and effectiveness make it a go-to for budget-conscious pool owners seeking reliable solar heating and debris protection.
Pros:- Simple to install and remove without fuss
- Reduces water evaporation by 95%, saving water and chemicals
- Protects from debris, keeping pool cleaner
- Affordable with durable polyethylene material
Cons:- Limited to 16-foot round pools, not adaptable to other shapes or sizes
- No manufacturer warranty included, potential long-term risk
- Performance may decline under overcast conditions
Best for: Owners of 16-foot round pools wanting an easy and economical way to reduce evaporation and extend swimming season.
Not ideal for: Those with irregularly shaped pools or larger pools, since this cover is designed specifically for 16-foot rounds and lacks flexibility.
- Suitable Pool Size:16 ft round
- Material:Polyethylene
- Purpose:Insulation, debris protection
- Warranty:None
Our verdict“Ideal for budget-conscious owners of 16-foot pools who want reliable evaporation reduction and easy handling.”
Intex Solar Pool Cover for 15ft Round Above Ground Pools
This 15-foot pool cover is tailored for smaller above-ground pools, providing effective insulation to keep water warmer and reducing evaporation by 95%. Compared with the 16-foot version, it offers a snug fit that enhances heat retention, though it’s less versatile for other sizes. Its simplicity makes it easy to use, but it lacks UV resistance details, which could affect durability over time. It’s best suited for owners who want an affordable, dedicated solution for their 15-foot pools, but those with larger or irregular pools should look elsewhere.
Pros:- Simple to install and remove, ideal for quick use
- Reduces evaporation by 95%, conserving water and chemicals
- Helps maintain warmer water temperatures
- Cost-effective for smaller pools
Cons:- Limited to 15-foot round pools, not adaptable
- No info on UV resistance or long-term durability
- May require removal during heavy rain or wind to avoid damage
Best for: Owners of 15-foot round above-ground pools seeking straightforward insulation and debris control.
Not ideal for: Pool owners with larger, irregular, or more complex pool shapes, as this is designed for a specific size and shape.
- Pool Size Compatibility:15-foot round
- Material:Polyethylene
- Features:Insulation, debris protection, evaporation reduction
Our verdict“A practical choice for owners of 15-foot pools prioritizing insulation and ease of use on a budget.”
VINGLI 18x36ft Solar Pool Cover 12mil Rectangle Blue
The VINGLI 18×36 ft cover offers a sizable, heavy-duty option for extending swimming seasons and reducing evaporation across larger or irregular pools. Its 12-mil thick material with welded seams emphasizes durability, making it suitable for frequent use and harsh weather. Compared to smaller, shape-specific covers like the Intex models, this cover’s size and flexibility for cutting make it a versatile choice. However, the bubble side appearing deflated initially can concern some users, and it requires a reel for easier handling. This cover suits pool owners seeking a durable, customizable solution rather than a simple fit for standard sizes.
Pros:- Large size suitable for big or irregular pools
- Heavy-duty with welded seams for enhanced durability
- Easy to cut to fit various shapes and sizes
- Effective at retaining heat and reducing evaporation
Cons:- Bubble side may appear deflated before sun exposure, impacting initial appearance
- Requires a pool cover reel for easier handling
- No specific info on UV resistance or long-term durability
Best for: Owners of large, irregular, or custom-shaped pools needing a durable, cut-to-fit solar cover.
Not ideal for: People with small or standard-shaped pools who prefer a ready-made, shape-specific cover for convenience.
- Size:18×36 ft
- Thickness:12 mil
- Shape:Rectangle
- Material:Heavy-duty PE
- Features:Welded seams, customizable cut
Our verdict“Best suited for pool owners with large or custom-shaped pools who need a tough, adaptable cover that lasts through tough conditions.”
BigXwell Heavy-Duty Solar Pool Cover 16x32ft – 16Mil Blue
The BigXwell 16×32 ft cover stands out for its thick 16-mil construction and thermal bubbles designed to trap heat efficiently, making it ideal for maintaining warm water during cloudy days or nights. Compared with thinner covers like the Intex or VEVOR options, its durability and heat retention capabilities are superior, especially in challenging weather conditions. However, the need for manual trimming for a perfect fit and the limited warranty details can be inconveniences. This product appeals most to owners of both inground and above-ground pools who prioritize long-term durability and consistent heating performance over ready-to-apply simplicity.
Pros:- Highly effective at heat retention with thermal bubbles
- Thick 16-mil construction for durability and longevity
- Easy to trim for custom fit and shapes
- Reduces evaporation by 95%, conserving water and chemicals
Cons:- Requires manual trimming for perfect fit, which can be labor-intensive
- Limited warranty information may concern long-term buyers
- Performance depends heavily on sunlight availability
Best for: Pool owners needing a heavy-duty, high-performance cover for diverse weather conditions and longer season extension.
Not ideal for: Casual users or those with pools that require a ready-made fit, since it may need trimming and potentially lacks a warranty.
- Size:16×32 ft
- Mil Thickness:16 Mil
- Color:Blue
- Material:PE
- Application:Inground or above-ground pools
Our verdict“Ideal for owners seeking a robust, long-lasting solar cover that can handle tough weather and maximize heat retention.”
VEVOR Solar Pool Cover, 24 x 12 ft Rectangle Solar Cover 16 mil for Pools, Inground and Above Ground Swimming Pool, Bubble Solar Blanket, Blue
This VEVOR 24 x 12 ft cover offers a practical size for mid-sized pools, standing out for its ability to effectively retain heat and cut evaporation for a lower-cost option. Unlike the larger 32 x 16 ft covers, it’s easier to handle and store, though it still requires manual cutting to fit non-standard shapes. Its 16 mil PE material provides durability against sun exposure, but its bulk can make handling cumbersome without assistance. This model is ideal for pool owners seeking a reliable, cost-effective cover that extends the swimming season, especially when a custom fit is desired. However, those with irregularly shaped pools may find cutting more challenging. Compared to the 32 x 16 ft options, it’s less unwieldy but less versatile in coverage size.
Pros:- Efficiently retains heat to extend swimming season
- Reduces evaporation by up to 95%
- Durable PE material resists sun damage and tearing
Cons:- Requires manual cutting for custom fit
- Handling can be difficult due to size and weight
Best for: Owners of medium-sized pools who want an affordable, durable cover with good heat retention.
Not ideal for: Pool owners with irregularly shaped pools who prefer a ready-to-apply cover without manual customization.
- Size:24 x 12 ft
- Material:16 mil PE
- Color:Blue
- Shape:Rectangle
- Application:Inground and Above Ground Pools
Our verdict“This cover makes the most sense for pool owners seeking a durable, budget-friendly option for standard-sized pools.”
VEVOR Solar Pool Cover 32 x 16 ft, 16 Mil Rectangle Solar Blanket Blue
This 32 x 16 ft cover is designed for bigger pools, offering excellent heat retention and evaporation reduction, comparable to the smaller 24 x 12 ft option but with a larger coverage area. Its 16 mil PE material withstands prolonged sun exposure, making it suitable for extended outdoor use. While it’s a solid choice for increasing water temperature by up to 15°C, the need for manual cutting can pose challenges for those unfamiliar with DIY fitting. It’s ideal for owners with sizeable pools who want a cost-effective solution that can be tailored to irregular shapes. Compared to smaller covers, it provides broader coverage, but the increased size makes handling and installation more labor-intensive.
Pros:- Extends swimming season by increasing water temperature
- Reduces evaporation by up to 95%
- Durable, sun-resistant PE material
Cons:- Requires cutting for a proper fit, which can be tricky
- Heavy and somewhat cumbersome to handle
Best for: Owners of large pools needing a customizable, heat-retaining cover that’s cost-effective.
Not ideal for: Pool owners with small or irregularly shaped pools who prefer a ready-made, no-cut solution.
- Size:32 x 16 ft
- Thickness:16 Mil
- Material:PE (Polyethylene)
- Color:Blue
Our verdict“This cover suits large pool owners seeking a customizable, economical solution for longer swimming seasons.”
VEVOR Solar Pool Cover 32 x 16 ft 16 Mil Pool Bubble Cover Blue & Black
Combining blue and black colors, this 32 x 16 ft cover adds an extra layer of versatility with its micro bubble design, supporting both inground and above ground pools. Its dual-color surface enhances heat absorption, with black on the bottom maximizing insulation. Compared to all-blue options like the previous models, this one offers improved heat retention, especially in windy or variable conditions. It’s made from durable PE, capable of reducing evaporation by up to 95%, and its easy trimming feature makes it adaptable to irregular shapes. However, the need for manual trimming and potential reduced effectiveness in very windy environments are tradeoffs. It’s best suited for owners seeking a flexible, high-performance cover that can adapt to unique pool contours.
Pros:- Micro bubbles enhance heat retention
- Supports irregular pool shapes with easy trimming
- Dual-color design improves insulation and heat absorption
Cons:- Requires manual trimming, which can be difficult
- Less effective in very windy conditions
Best for: Pool owners with irregular shapes or those who want a more adaptable, high-efficiency cover.
Not ideal for: Purely traditional pool owners with straightforward, standard-sized pools who prefer pre-cut covers.
- Size:32 x 16 ft
- Thickness:16 Mil
- Color:Blue & Black
- Material:PE
Our verdict“This cover is ideal for owners who need a flexible, efficient solution that can fit complex pool shapes and maximize heat gain.”
VEVOR Solar Pool Cover 40 x 20 ft, 16 Mil Rectangle Solar Blanket Blue
This 40 x 20 ft cover stands out for its generous size, making it suitable for large pools and those who prioritize maximizing heat retention. Its 16 mil PE material offers durable insulation, helping to extend the swimming season by increasing water temperature and reducing evaporation by up to 95%. Unlike smaller covers such as the Intex 28012E, it provides broader coverage with less need for multiple layers. However, the size can make handling and installation more challenging, especially for smaller pool owners. It works well in sunny conditions but may be less effective in very cold or cloudy weather. This pick makes sense for owners with large pools who want a reliable, high-capacity cover to retain heat and save energy.
Pros:- Extends swimming season through superior heat retention
- Reduces evaporation significantly
- Durable and resistant to sun exposure
Cons:- Handling can be cumbersome due to large size

Intex 28012E Solar Pool Cover for 12ft Round Pools
This cover is tailored specifically for 12-foot round Intex pools, making it a straightforward choice for owners of these models. Its simple plastic design offers effective insulation, reducing evaporation and helping to keep debris out. Compared to larger covers like the VEVOR 24 x 12 ft, it’s easier to handle and install but lacks the versatility for irregular shapes or larger pools. Its affordability makes it appealing for budget-conscious owners, but the red color can fade over time, and it requires removal for swimming. While not suitable for larger or differently shaped pools, it provides reliable performance for its intended size.
Pros:- Easy to install and remove
- Reduces water evaporation by 95%
- Affordable and durable for small pools
Cons:- Limited to 12 ft round pools
- Color may fade over time
- Requires removal for swimming

Our verdict“This cover is best suited for small, round Intex pools where simplicity and affordability are valued.”
VEVOR Solar Pool Cover, 24 x 12 ft Rectangle, 12 mil Bubble Solar Blanket for Pools
This VEVOR rectangular cover stands out for its generous size and durable 12mil polyethylene construction, making it a strong choice for both inground and above-ground pools. Compared to the VEVOR 32 x 16 ft cover, it offers a more manageable size for smaller pools, though it still provides excellent heat retention and evaporation reduction. The bubble design effectively traps solar heat, extending swimming seasons and lowering heating costs. However, its large size can make handling cumbersome, especially if you need a custom fit, as it may require cutting. Its durability against sun exposure is a plus, but lack of specific warranty details could be a concern for long-term buyers. This pick makes the most sense for pool owners seeking a reliable, all-around cover that balances size with durability, especially if they prefer a model that’s easier to store and manage than larger covers.
Pros:- Effective heat retention extends swimming season
- Reduces evaporation by up to 95%
- Durable and resistant to sun exposure
- Customizable shape with cutting flexibility
Cons:- May be difficult to handle due to size
- Requires cutting for irregular shapes

- Material:PE (Polyethylene)
- Color:Blue
- Application:Inground and above ground pools
Our verdict“This cover is best for pool owners seeking a durable, all-purpose solution that balances size and longevity.”
In The Swim 21′ Standard Blue Round Solar Pool Cover 8 Mil
Compared with larger or thicker covers, the In The Swim 21′ 8 Mil cover emphasizes lightweight handling and affordability. Its 8-mil thickness offers sufficient solar heat retention for smaller pools but may fall short in durability over time, especially with frequent handling or harsh sunlight. Its lightweight polyethylene makes it easy to trim and install, ideal for DIY pool owners who want a quick, cost-effective solution. However, the thinner material means it might not last as long as thicker options like the Blue Wave 16×32 ft cover, which offers more durability at a higher price. This model is perfect for owners of 21-foot pools or those seeking a simple, budget-friendly cover that’s easy to manage but willing to accept some tradeoffs in longevity.
Pros:- Lightweight and easy to handle
- Reduces water evaporation and chemical use
- Affordable price point
- Easy to trim for a custom fit
Cons:- Less durable due to thinner material
- Requires trimming around ladders or steps
- Limited to 21-foot pools
Best for: Owners of small to medium-sized pools who prioritize ease of use and affordability
Not ideal for: Pool owners with large or irregularly shaped pools needing a more durable, long-lasting cover
- Size:21 feet
- Material:Polyethylene
- Thickness:8 Mil
- Color:Blue
Our verdict“Ideal for budget-conscious pool owners who want a straightforward, easy-to-install solar cover for smaller pools.”
Blue Wave 16×32-ft Rectangle Solar Pool Cover 12-Mil Blue
The Blue Wave 16×32 ft cover offers a solid balance of size and performance, with its 12-mil thickness providing enhanced durability over thinner covers like the In The Swim 21′ 8 Mil. Its thermal bubble technology effectively captures solar heat, making it suitable for both inground and above-ground pools, and extending swim times into cooler seasons. Its lightweight design simplifies handling and installation, but it may require trimming to fit non-standard pool sizes, which could be a hassle for some users. The blue color helps with heat absorption but can show dirt more visibly. Compared to larger models, this size is manageable for most homeowners, yet it still delivers good energy efficiency. This cover suits pool owners seeking a reliable, mid-size option that improves energy savings without the bulk of larger covers.
Pros:- Enhances heat retention and reduces evaporation
- Durable 12-mil construction
- Easy to handle and install
- Suitable for both inground and above-ground pools
Cons:- May need trimming for non-standard sizes
- Blue color may hide dirt less effectively
- Performance depends on sunlight

Not ideal for: Those with irregularly shaped or very small pools who prefer a tailored fit or a lighter option
- Size:16×32 ft
- Thickness:12 Mil
- Color:Blue
- Material:Polyethylene
Our verdict“This cover makes a strong choice for pool owners looking for a durable, energy-efficient solution for standard-sized pools.”
VEVOR Solar Pool Cover 32 x 16 ft Rectangle 12 Mil Bubble Solar Blanket for Inground and Above Ground Pools
This VEVOR 32 x 16 ft cover is designed for larger pools, combining a generous size with high-performance 12mil bubble technology. It excels at increasing water temperature by up to 15°C, making it ideal for extending swim seasons and improving energy efficiency. Its durability against sun exposure and tearing surpasses thinner options, such as the In The Swim 21′ 8 Mil, and its customization potential allows it to fit various pool shapes with cutting. Handling this size may be cumbersome for smaller pools or irregular shapes, and it requires cutting for precise fit. Its strong heat retention capabilities make it perfect for owners seeking significant temperature boosts and water conservation, but it may need replacement after prolonged exposure or wear. Overall, this cover is best suited for large, in-ground pools where maximizing heat gain is a priority.
Pros:- Increases water temperature by up to 15°C
- Reduces evaporation by up to 95%
- Durable and resistant to sun and tearing
- Customizable to fit various pool shapes
Cons:- Requires cutting for irregular shapes
- Potentially cumbersome to handle
- May need replacement after extensive wear

Our verdict“This cover is best for large pool owners seeking maximum heat retention and energy efficiency with a customizable fit.”
In The Swim 18′ Premium Blue Round Solar Pool Cover 12 Mil
Compared with the In The Swim 21′ 8 Mil, this 18-foot round cover emphasizes durability and a longer warranty, with a 7-year coverage period. Its 12-mil polyethylene construction offers robust heat retention and evaporation reduction, making it well-suited for owners who want a resilient cover that can withstand frequent use and sunlight. Its ability to be trimmed for a precise fit adds flexibility, but manual trimming is necessary for an optimal fit, which may be inconvenient for some. While it may not be ideal for very small or irregular pools, this model balances durability and performance for standard round pools. The 12mil thickness also offers a good compromise between longevity and ease of handling, making it suitable for owners who prioritize long-term value.
Pros:- Helps retain heat and extend the swimming season
- Heavy-duty 12-mil polyethylene for durability
- 7-year manufacturer warranty
- Customizable fit by trimming
Cons:- Requires manual trimming for perfect fit

Not ideal for: Pool owners with irregular or very small pools who need a ready-made, no-trim solution
- Size:18 feet
- Material:12 Mil polyethylene
- Color:Blue
- Warranty:7 years
Our verdict“This cover is best for owners of standard 18-foot round pools who want a durable, long-term solution with a warranty to match.”

How We Picked
I evaluated these solar pool covers based on several key factors: material thickness, which impacts heat retention and durability; size and shape compatibility with common pools; build quality and UV resistance for long-term use; ease of handling and installation; and overall value considering price versus lifespan. Products were ranked to reflect the best balance of these qualities for different types of pool owners, from budget-conscious buyers to those seeking premium durability. The selection emphasizes real-world performance and usability, ensuring each pick addresses common buyer needs and tradeoffs effectively.Factors to Consider When Choosing Solar Pool Cover
Choosing the right solar pool cover involves understanding how different features impact performance and maintenance. Beyond initial cost, factors like thickness, material quality, and compatibility influence long-term savings and pool efficiency. Being aware of these considerations helps prevent common mistakes, such as overpaying for unnecessary thickness or buying a cover that doesn’t fit your pool shape. This guide highlights key aspects to consider so you can select a cover that balances cost, durability, and effectiveness.Material Thickness and Durability
Thickness, measured in mils, directly affects a cover’s ability to retain heat and resist wear. Thicker covers (around 16-20 mil) typically last longer and provide better insulation, but they also tend to be more expensive and heavier. Cheaper, thinner covers (around 8-12 mil) may be easier to handle but often degrade faster, especially under strong sun exposure. When choosing, consider how much wear your cover will endure and whether ease of handling outweighs longevity.
Pool Size and Shape Compatibility
Matching your cover size to your pool’s dimensions is critical for optimal performance. A cover that’s too small won’t maximize heat retention, while an oversized cover can be cumbersome to handle and may trap debris. Rectangular covers work well for standard pools, but irregular shapes or rounded pools require specially shaped covers for best fit. Measure your pool carefully before purchasing to ensure efficiency and ease of use.
Material Quality and UV Resistance
High-quality materials with UV inhibitors extend the lifespan of your solar cover by resisting sun damage and cracking. Cheaper options often lack these features, leading to brittleness and reduced effectiveness over time. Look for covers with strong, durable polymers that can withstand outdoor exposure without deteriorating quickly. Investing a bit more upfront in better materials can translate into longer-lasting, more reliable performance.
Ease of Handling and Installation
Lightweight and flexible covers are easier to install and remove, especially for smaller pools or those with limited mobility. Thicker, heavier covers may require additional effort or tools for handling, which can be inconvenient frequently. Consider features like handles or roll-up designs if ease of handling is a priority. Balancing weight with durability is key to making daily pool maintenance manageable.
Cost versus Value
While budget options may seem attractive initially, they often require more frequent replacement, increasing overall costs. Premium covers, though more expensive, tend to last longer and provide better insulation, saving money over time. Evaluate your long-term needs, pool size, and how much you’re willing to invest upfront. The goal is to find a cover that offers the best performance for your budget, considering both initial purchase price and longevity.
Frequently Asked Questions
How does thickness affect the heat retention of a solar pool cover?
Thicker solar pool covers, typically around 16-20 mils, improve heat retention because they trap more heat and reduce evaporation. The increased material density enhances insulation, helping your pool stay warmer for longer periods. However, thicker covers also tend to be heavier and more cumbersome to handle, so balancing thickness with ease of use is important when selecting the right product for your needs.
Can a solar pool cover fit any pool shape and size?
Not all covers are compatible with every pool shape or size. Rectangular covers suit standard pools, but irregular or round pools require specific shapes to ensure proper coverage. Always measure your pool accurately and select a cover designed for your pool’s dimensions. Improper fit can lead to reduced heat efficiency or increased debris accumulation, so precision in sizing matters significantly.
How long do solar pool covers typically last?
The lifespan of a solar pool cover depends on material quality, thickness, and exposure to sunlight. Good quality covers with UV inhibitors can last 3-5 seasons with proper care. Cheaper, thinner covers might need replacement after just a season or two, especially if exposed to harsh sunlight or chemicals. Regular cleaning and avoiding sharp objects during handling can extend your cover’s usability.
Is it worth investing in a premium solar pool cover?
Investing in a premium cover often pays off over time, as these tend to be more durable, better insulated, and resistant to UV damage. While the initial cost is higher, the longer lifespan and improved efficiency can reduce your heating costs and replacement frequency. Premium options are especially beneficial for larger or more frequently used pools where consistent performance impacts your swimming comfort and energy savings.
What features make a solar pool cover easier to handle?
Look for lightweight designs, handles, or roll-up features that facilitate easy installation and removal. Some covers come with reinforced edges or built-in handles, reducing strain during handling. Choosing a slightly thinner but durable cover can also improve manageability, especially if you need to frequently remove or adjust the cover. Ease of handling is a key factor in making routine pool maintenance less of a chore.
Conclusion
For most pool owners seeking a reliable, all-around option, the Intex Solar Pool Cover offers a solid balance of durability and affordability. Those prioritizing longevity and maximum heat retention should consider premium options like the BigXwell Heavy-Duty Cover, especially for larger or high-use pools. Budget-conscious buyers will find value in thinner, simpler covers but should be prepared for more frequent replacements. Beginners or casual pool owners benefit from lightweight, easy-to-handle models, while experienced users with larger pools might prefer custom or dual-layer designs for enhanced performance. Ultimately, your choice depends on your pool size, climate, and how much you’re willing to invest for energy savings and convenience.
