More Details on Our Top Picks
VEVOR Solar Pool Cover 40 x 20 ft, 16 Mil Rectangle Solar Blanket Blue
This VEVOR 40 x 20 ft solar pool cover stands out for its combination of durability and customization. Its 16mil PE material provides excellent resistance to sun and chemical exposure, making it suitable for frequent use. Compared with the smaller In The Swim 18′ cover, this option offers a larger coverage area, ideal for bigger pools, but it requires careful handling to prevent tears during installation. Its ability to be cut to fit irregular pool shapes makes it highly adaptable, though improper trimming can lead to gaps that reduce efficiency. This model’s strength lies in its capacity to insulate and reduce evaporation for sizable pools, making it a practical choice for owners with larger or uniquely shaped pools who prioritize durability and flexibility.
Pros:- Highly durable and resistant to sun and chemical exposure
- Large coverage area suitable for big or irregular pools
- Can be cut to fit various shapes for a tailored fit
Cons:- Requires careful handling to avoid tearing during installation
- Needs trimming for irregular shapes, which can be cumbersome
Best for: Owners of large or irregularly shaped pools that need a durable, customizable cover.
Not ideal for: Pool owners with small or standard-sized pools who prefer easy-to-use, ready-fit covers without trimming.
- Brand:VEVOR
- Model Name:Solar Pool Cover
- Model Number:pool cover 400-40*20
- Material:PE (Polyethylene)
- Thickness:16 mil
- Color:Blue
Our verdict“This cover is best for owners with large or uniquely shaped pools who seek durability and customization despite handling challenges.”
In The Swim 18′ Standard Blue Round Solar Pool Cover 8 Mil
This 8-mil polyethylene cover from In The Swim offers a cost-effective way to extend your swimming season while reducing evaporation. Its lightweight design makes it easy to handle, especially compared to thicker covers like the Intex 18ft Round Solar Cover, which provides more durability at a higher cost. However, the thinner material means it may wear faster with frequent use or exposure to rough handling. Its ability to be trimmed allows a custom fit around ladders and steps, but owners must be comfortable with manual adjustments. This cover makes the most sense for owners of small pools who want an affordable, straightforward solution that effectively conserves heat and water without the need for high-end features or long-term durability.
Pros:- Cost-effective and easy to trim for custom fitting
- Lightweight and simple to handle
- Effective at reducing evaporation and extending season
Cons:- Less durable due to thinner 8-mil material
- May require replacement after several seasons
Best for: Owners of small, 18-foot round pools seeking an affordable, easy-to-trim cover.
Not ideal for: Owners of larger or heavily used pools who need a more durable, long-lasting cover.
- Size:18 feet
- Color:Blue
- Material:Polyethylene
- Thickness:8 Mil
- Warranty:3 years
Our verdict“This cover is ideal for budget-conscious owners of small pools who prioritize affordability and ease of use over long-term durability.”
Sun2Solar Solar Pool Cover 16 Mil, 18 x 36 Ft, Blue
Compared to the smaller Intex 28014E, the Sun2Solar 16 mil cover provides a larger surface for bigger pools, making it a better choice for above ground and inground pools up to 18 x 36 ft. Its thicker 16mil design offers enhanced durability and insulation, capable of raising water temperature by up to 15°F. The heat-trapping bubbles efficiently prevent up to 95% of evaporation, conserving water and chemicals. However, its size can make handling and storage more challenging, especially for owners with limited space or less strength. This model’s high insulation makes it well-suited for owners looking to maximize heat gain and water savings in larger pools, though it demands more effort to manage properly.
Pros:- Raises water temperature significantly without extra energy costs
- Prevents up to 95% of water evaporation
- Durable 16 mil resin resists warping and fading
- Large coverage area ideal for big pools
Cons:- Handling and storing large size can be difficult
- May require trimming for non-standard pool shapes
Best for: Owners of large above ground or inground pools who want maximum insulation and evaporation control.
Not ideal for: Pool owners with small or irregularly shaped pools that cannot accommodate such a large cover comfortably.
- Brand:Sun2Solar
- Thickness:16 mil
- Dimensions:18 x 36 ft
- Color:Blue
- Temperature Increase:Up to 15°F
- Material:Durable resin
Our verdict“This cover is best suited for large pools where maximum heat retention and evaporation reduction are priorities, despite handling challenges.”
In The Swim 18′ Premium Blue Round Solar Pool Cover 12 Mil
This 12-mil polyethylene cover from In The Swim offers a strong balance of durability and performance, making it suitable for owners who want a long-lasting solution. Its thicker 12mil material provides better resistance to tears and UV damage compared to thinner options like the 8-mil cover, ensuring it can withstand multiple seasons. Its ability to warm water naturally and reduce evaporation makes it a practical choice for those looking to extend their swimming season while conserving resources. However, the heavier weight can make handling more cumbersome, and trimming is necessary for a perfect fit around irregular features. This pick makes the most sense for dedicated pool owners wanting durability and efficiency in a premium model, even if it requires more effort to manage.
Pros:- Heavy-duty 12 mil polyethylene for enhanced durability
- Effective at warming water and reducing evaporation
- Long-term performance with a 7-year warranty
- Can be trimmed for a custom fit
Cons:- Heavier and more cumbersome to handle
- Requires manual trimming for irregular shapes
Best for: Owners seeking a durable, long-lasting cover for regular seasonal use on 18-foot round pools.
Not ideal for: Owners of smaller pools or those seeking a lightweight, easy-to-install cover for occasional use.
- Brand:In The Swim
- Model Name:12MIL 18RND
- Model Number:12MIL 18RND
- UPC:803354900749
- Warranty:7 Years
- Unit Count:18 Feet
Our verdict“This premium cover is ideal for dedicated pool owners wanting long-term durability and reliable performance despite handling weight.”
Intex Solar Pool Cover for 18ft Round Above Ground Pools
Designed specifically for 18-foot round pools, the Intex Solar Cover offers straightforward protection with minimal fuss. Its simple, ready-fit design makes installation quick, and its 8-mil material provides basic resistance to UV and physical wear. While it doesn’t offer the durability of thicker covers like the In The Swim 12mil, it effectively reduces evaporation and debris entry, making it suitable for owners who prioritize convenience and a perfect fit for their specific pool size. Its lack of a warranty and limited size options mean it’s less adaptable for irregular pools or heavy seasonal use. This cover works well for users who want an affordable, no-hassle solution that does its job without extra features or customization.
Pros:- Easy to install and remove
- Effective at reducing evaporation and debris
- Designed specifically for 18-foot pools for a perfect fit
Cons:- Limited durability due to thinner 8-mil material
- No warranty included
Best for: Owners of 18-foot round above ground pools seeking a simple, hassle-free cover.
Not ideal for: Pool owners with larger, irregular, or high-usage pools who need more durable or flexible options.
- Brand:Intex
- Model Name:18FT Round Solar Cover
- Model Number:28015E
- UPC:078257316618
- Item Part Number:FPS-91765
- Warranty:No Applicable Warranty
Our verdict“This cover is best for owners of 18-foot round pools who want a straightforward, budget-friendly option for seasonal protection.”
VEVOR Solar Pool Cover 32 x 16 ft, 16 Mil Rectangle Solar Blanket, Blue
This VEVOR cover stands out for its large size and durable 16 mil PE construction, making it suitable for both inground and above-ground pools. Compared with the Blue Wave 16′ x 32′ cover, it offers a bigger area for larger pools but requires more effort to handle and position. Its ability to increase water temperature by up to 15°C and reduce evaporation by 95% makes it highly effective, though actual heating depends heavily on environmental conditions. The option to trim it for custom shapes adds flexibility, but its size may challenge users with smaller pools or limited storage space. While it’s robust and long-lasting, the larger size may involve more effort during installation and removal, especially for those with limited physical strength or storage options.
Pros:- Helps increase pool water temperature by 8-15°C depending on conditions
- Reduces water evaporation by up to 95%
- Durable 16 mil PE construction resists sun damage and tearing
- Can be trimmed to fit different pool shapes
Cons:- Size makes handling and positioning more labor-intensive
- Heating performance varies with weather and sunlight exposure
Best for: Homeowners with large or irregularly shaped pools seeking a durable, versatile cover that maximizes heat retention.
Not ideal for: Pool owners with small or standard-sized pools who prefer a lightweight, easy-to-manage cover.
- Size:32 x 16 ft
- Shape:Rectangle
- Thickness:16 mil
- Color:Blue
- Material:PE
- Installation Type:Floating
- Best Sellers Rank:#1,674 in Patio, Lawn & Garden
Our verdict“This cover is best suited for users with larger pools who need a tough, customizable solution to extend their swimming season.”
Blue Wave 16′ x 32′ Rectangle Solar Pool Cover, 12-Mil Blue
This Blue Wave cover is a practical choice for those with 16×32-ft pools, offering a lightweight 12-mil design that simplifies handling. Unlike the heavier VEVOR, its lower thickness means easier placement and removal, making it ideal for pool owners who prefer quick, straightforward maintenance. It works well for both above-ground and inground pools, providing reliable heat retention and evaporation reduction, similar to the Intex 28014E, but with a longer warranty of 5 years. The ability to trim it with household scissors gives a custom fit for ladders and accessories, though the thinner material requires careful storage to avoid tears or damage. Its performance is weather-dependent, and it may need to be stored carefully to maximize lifespan.
Pros:- Works with both above-ground and inground pools
- Lightweight 12-mil design for effortless handling
- Reduces evaporation and debris buildup
- Trimtable to fit ladders and accessories
Cons:- Performance depends on sunny weather
- Requires careful storage to prevent damage
Best for: Owners of 16×32-ft pools who want a lightweight, easy-to-handle cover with reliable performance.
Not ideal for: Pool users in variable climates or those looking for a heavier, more durable cover for harsher conditions.
- Size:16 x 32 ft
- Shape:Rectangle
- Thickness:12 mil
- Color:Blue
- Pool Type:Above-ground and inground
- Warranty:5-year limited
Our verdict“This cover is excellent for owners seeking a lightweight, adaptable solution that balances ease of use with reliable heat retention.”
Intex 28014E Solar Pool Cover for 16ft Round Easy Set and Metal Frame Pools
This Intex cover offers straightforward use for 16-ft round pools, emphasizing ease of deployment with its simple flat placement. Its bubble design efficiently absorbs solar heat and insulates, reducing evaporation by up to 95%, similar to the Blue Wave but tailored specifically for round pools. The cover’s design means it’s quick to lay on and remove, ideal for pool owners who prioritize convenience. However, its specificity to 16-ft round pools limits flexibility—if your pool size or shape varies, this cover may not fit well. Also, the absence of drain holes can lead to rainwater pooling, which might require manual removal. Despite this, it remains a reliable, economical option for typical round above-ground pools.
Pros:- Very easy to use—simply lay flat on the pool surface
- High evaporation reduction of up to 95%
- Keeps debris out and reduces chemical use
- Affordable and lightweight
Cons:- Designed specifically for 16ft round pools only
- No drain holes may cause rainwater to pool
Best for: Owners of 16ft round above-ground pools seeking an easy, no-fuss solar cover that reduces evaporation and debris.
Not ideal for: Pool owners with irregular or larger pools, or those needing a cover with drainage features.
- Compatible Pool Size:16 ft round
- Material:Bubble design
- Evaporation Reduction:95%
- Pool Type:Easy Set and Metal Frame
Our verdict“This cover is perfect for owners of 16ft round pools who want quick, effective, and simple solar protection.”
BigXwell Heavy-Duty Solar Pool Cover 16 x 32 ft, 16 Mil, Blue
Compared with the VEVOR and Blue Wave options, the BigXwell cover emphasizes durability with its 16 mil thickness and heavy-duty PE material, making it suitable for both residential and commercial pools. Its thermal bubbles effectively trap heat, helping maintain pool temperature in varied weather, from sunny to cloudy. The ability to trim the cover adds flexibility, but heavy-duty construction means it’s somewhat bulkier, requiring more effort during handling. Its performance depends on sunlight exposure, and manual coverage may be necessary, especially in shaded conditions. This cover’s rugged build makes it a strong choice for demanding environments, but less so for owners prioritizing lightweight or quick deployment.
Pros:- Helps retain heat and reduce evaporation effectively
- Heavy-duty 16 mil PE resists tears and sun damage
- Can be trimmed for custom fit
- Suitable for various pool types and conditions
Cons:- Heavier and bulkier to handle
- Requires manual effort for covering and removal
Best for: Commercial or large residential pool owners needing a highly durable cover that withstands frequent use and harsh conditions.
Not ideal for: Pool owners with smaller or infrequently used pools who prefer lightweight, easy-to-move covers.
- Size:16 x 32 ft
- Thickness:16 mil
- Color:Blue
- Material:PE
- Features:Trim-to-fit, thermal bubbles
Our verdict“This heavy-duty cover is best suited for large or demanding pools needing a resilient, long-lasting thermal barrier.”
VEVOR Solar Pool Cover, 24 x 12 ft Rectangle, 16 mil Blue Solar Blanket for Inground and Above Ground Pools
This VEVOR cover offers a practical balance between size and durability, with a 24 x 12 ft rectangle suited for a variety of pools. Its 16 mil PE material with heat-trapping bubbles helps raise water temperatures by up to 15°C and reduces evaporation by 95%, similar to the larger VEVOR model but designed for smaller pools. It provides a flexible, trim-to-fit option, making it suitable for both inground and above-ground pools of different shapes. While its performance can vary depending on sunlight and weather, it offers reliable thermal protection for users who want an effective yet manageable cover. The main tradeoff involves cutting to size, which might be inconvenient for some
Pros:- Raises water temperature by up to 15°C
- Reduces evaporation and debris
- Can be trimmed for a custom fit
- Durable 16 mil PE material resists sun wear
Cons:- Temperature gains depend on environmental factors
- Requires cutting for custom shapes, which may be inconvenient
Best for: Pool owners with moderate-sized pools seeking a durable, flexible cover that boosts heat retention efficiently.
Not ideal for: Owners with very large or irregularly shaped pools who need more coverage or a larger size.
- Size:24 x 12 ft
- Shape:Rectangle
- Thickness:16 mil
- Material:PE
- Compatibility:Inground and above ground
Our verdict“This VEVOR model offers a strong choice for owners of moderate pools needing reliable heat and evaporation control with flexible sizing.”
Intex Solar Pool Cover for 15 ft Round Above Ground Swimming Pools
This Intex solar cover is tailored specifically for 15-foot round above-ground pools, making it a straightforward choice for those with this pool size. It excels at absorbing solar heat to warm your water, outperforming traditional covers that only block debris. Compared to larger or more versatile options like the VINGLI 18×36 ft cover, this one offers a focused fit but limits flexibility. Its ease of use and debris protection are clear advantages, but it depends heavily on sunlight exposure for heating, which can be inconsistent. The insulation and evaporation reduction features help extend your swimming season while cutting water and chemical costs. Ideal for owners of small, round above-ground pools seeking a simple, budget-friendly solar solution. However, it’s less suitable if your pool isn’t exactly 15 feet or if you want a more universal, multi-shape cover.
Pros:- Specifically designed for 15 ft round above-ground pools for perfect fit
- Helps warm water using solar energy, reducing heating costs
- Reduces debris and trash, keeping pool cleaner
- Low maintenance and easy to place on pool surface
Cons:- Limited to 15-foot round pools; not adaptable to other sizes or shapes
- Heating performance varies with sunlight intensity, affecting efficiency
Best for: Owners of 15-foot round above-ground pools looking for an affordable, easy-to-install solar cover.
Not ideal for: Pool owners with irregularly shaped or larger pools, or those seeking a cover that works equally well without direct sunlight.
- Brand:Intex
- Product Type:Solar Pool Cover
- Compatible Pool Size:15 ft Round
- Pool Type:Above Ground
- Shape:Round
- Evaporation Reduction:95%
Our verdict“This cover is best suited for owners of small, round above-ground pools who prioritize simplicity and cost-effectiveness in solar heating.”
In The Swim 21′ Standard Blue Round Solar Pool Cover 8 Mil
This 21-foot round solar cover from In The Swim offers a larger size and thicker material compared to the Intex 15 ft model, making it suitable for bigger pools and more durable over multiple seasons. Its 8-mil thickness strikes a good balance between flexibility and durability, allowing owners to trim it for a customized fit—an advantage over thinner, less durable covers like some 6-mil options. While it requires manual trimming for a perfect fit, this feature is valuable for owners with irregular pool shapes or ladders. Compared to the VINGLI 18×36 ft cover, it is more manageable for smaller pools but less versatile for larger or irregular pools. It retains heat effectively, prolongs your swimming season, and reduces water and chemical use. The 3-year warranty adds peace of mind, but the need for replacement after some seasons, depending on use, is a consideration. This cover is ideal for pool owners seeking a mid-sized, durable solar blanket with customization options. If you prefer a pre-cut, ready-to-use cover, this might be less convenient than fixed-size options.
Pros:- Larger 21-foot size for bigger pools, extending usability
- Thicker 8-mil polyethylene enhances durability and longevity
- Can be trimmed for a perfect fit around ladders or irregular shapes
- Helps retain heat and reduce evaporation effectively
Cons:- Requires manual trimming for a tailored fit, which can be time-consuming
- May need replacement after several seasons depending on exposure and use
Best for: Owners of larger round pools up to 21 feet who want a durable, customizable solar cover to extend their swimming season.
Not ideal for: Owners of irregular or very small pools, or those who prefer a no-trim, ready-to-use cover for convenience.
- Size:21 Feet
- Material:8 Mil Polyethylene
- Shape:Round
- Color:Blue
- Warranty:3 Years
- Functions:Heat retention, evaporation reduction, customizable fit
Our verdict“This cover suits pool owners seeking a durable, customizable option that extends swimming seasons for larger round pools.”
VINGLI 18×36 ft Solar Pool Cover, 12 mil, Rectangle, Blue
The VINGLI 18×36 ft solar cover stands out for its generous size and heavy-duty 12-mil bubble material, making it a robust choice for rectangular pools that require extended heat retention. Its thick construction offers superior durability compared to thinner covers like the 8-mil In The Swim model, and its large size provides flexibility for various pool shapes. Owners can cut it to fit irregular shapes, but the bubble side must be placed down for optimal performance, which is a critical step for effectiveness. Compared with smaller, pre-cut options, this cover demands a bit more effort but offers better long-term resilience. It effectively reduces water evaporation, keeps debris out, and captures sunlight to prolong swimming seasons. A pool reel is recommended for easier handling, especially given its size and weight. This pick makes the most sense for owners of large, rectangular pools who want a durable, customizable solar blanket. It may be overkill for small pools or those seeking a fuss-free installation.
Pros:- Large 18×36 ft size suitable for big pools
- Thick 12-mil material offers enhanced durability and lifespan
- Can be cut to fit irregular shapes for a tailored fit
- Helps retain heat and reduce evaporation efficiently
Cons:- Bubble side must face downward for proper heat absorption
- Handling and trimming can be challenging without a reel or helper
Best for: Owners of large rectangular pools needing a heavy-duty, customizable solar cover to extend their swimming season.
Not ideal for: Pool owners with smaller or irregularly shaped pools who prefer ready-to-use covers without trimming or handling large sheets.
- Size:18 x 36 ft
- Thickness:12 mil
- Shape:Rectangle
- Color:Blue
- Material:Heavy-duty bubble solar blanket
- Installation:Bubble side down, can be cut to fit
Our verdict“This cover is best suited for owners of large, rectangular pools who need a durable, customizable solar blanket to maximize heat retention over many seasons.”
How We Picked
Our evaluation focused on several key criteria: coverage size, thickness (mil), material quality, UV resistance, and overall durability. We prioritized products that balance performance with value, ensuring they provide effective heat retention without excessive weight or difficulty in handling. Compatibility with popular pool sizes was also essential, along with ease of installation and maintenance. The ranking reflects a combination of these factors, favoring options that excel in both longevity and affordability while noting tradeoffs such as weight or price for premium features.
Factors to Consider When Choosing Solar Pool Cover
When selecting a solar pool cover, understanding the key factors that influence performance and convenience can help you make a smarter choice. Beyond price, consider how the cover’s thickness, material, and size will match your pool’s needs. Making the right decision can extend your swimming season, reduce your heating costs, and simplify maintenance. Here are the main considerations to keep in mind:Pool Size and Shape Compatibility
Ensuring the cover fits your pool properly maximizes its effectiveness. Rectangular covers are suited for inground pools, while round covers are designed for above-ground pools. An ill-fitting cover can allow heat to escape and reduce energy savings, so measuring your pool accurately before buying is essential. Many covers come in standard sizes, but custom options are available for non-standard pools. Picking a cover that matches your pool dimensions reduces waste and improves efficiency.
Thickness (Mil) and Durability
The thickness of a solar cover, measured in mils, directly impacts its durability and heat retention. Thicker covers (12-16 mil) tend to last longer and insulate better, but they are heavier and more difficult to handle. Thinner options, like 8 mil, are easier to manipulate but may require replacement sooner. Consider how often you’ll need to remove or replace the cover and your ability to handle heavier materials when choosing thickness.
Material Quality and UV Resistance
High-quality materials with strong UV resistance prolong the lifespan of your cover, especially in sunny climates. Look for covers made from durable, UV-stabilized polyethylene or similar materials, which resist cracking and fading. Investing in a more resistant material can pay off over time by reducing replacement frequency and maintaining heat efficiency. Cheaper options often degrade faster, so balance initial cost with long-term performance.
Ease of Handling and Installation
Handling a solar cover can be challenging, especially for larger or thicker models. Features like built-in handles, lightweight design, or roll-up systems can make installation and removal easier. Consider your strength and space—some covers require multiple people or specialized equipment. Ease of handling influences how often you’ll use the cover and how much effort you’ll invest in maintaining your pool’s warmth.
Cost-Effectiveness and Long-Term Value
While premium covers cost more upfront, their longer lifespan and better insulation can lead to savings over time. Conversely, cheaper covers may need frequent replacements, adding to your overall expense. Assess your pool usage, climate, and budget to find a balance. Investing in a durable, well-fitting cover pays off by maintaining pool temperature more efficiently and reducing heating costs.
Frequently Asked Questions
How long does a typical solar pool cover last?
The lifespan of a solar pool cover depends on its material quality, thickness, and climate conditions. Generally, a high-quality cover with UV protection can last 3 to 5 years, while cheaper models may need replacement after 1 to 2 seasons. Proper maintenance, such as cleaning and storing it away from harsh sunlight when not in use, can extend the lifespan. Investing in a durable, UV-resistant cover typically offers better long-term value despite a higher initial cost.
Will a larger cover waste energy if it overlaps the pool edges?
No, a slightly larger cover that overlaps the pool edges can actually improve heat retention by minimizing heat escape around the edges. However, excessive overlap may make handling more cumbersome. It’s best to choose a cover that fits your pool size closely, with just enough overhang to ensure complete coverage. Proper fitting enhances efficiency without adding unnecessary bulk.
Can I use a solar cover on an in-ground and an above-ground pool?
Yes, but you should select a cover designed for your pool type and size. Rectangular covers fit well with in-ground pools, while round ones are suited for above-ground pools. Using a cover that is too small or too large can reduce effectiveness and complicate handling. Always measure your pool accurately and choose a cover specifically recommended for your pool’s shape and dimensions.
Is a thicker solar cover always better?
Not necessarily. Thicker covers (12-16 mil) do offer better durability and insulation but can be heavier and harder to handle, especially for smaller or elderly users. Thinner options (8-10 mil) are easier to manipulate and may suffice for pools in mild climates or occasional use. Consider your handling preferences and climate conditions when opting for thickness; sometimes a balance between ease of use and longevity is ideal.
How do I clean and store my solar pool cover?
Cleaning your solar cover with a gentle brush and mild soap periodically removes dirt and debris that can degrade the material. Rinsing thoroughly prevents soap buildup that might reduce UV protection. When not in use, store the cover in a cool, shaded area away from direct sunlight to prevent UV damage. Proper cleaning and storage extend the life of your cover and maintain its insulating properties.
Conclusion
For most pool owners, the VEVOR Solar Pool Cover 40 x 20 ft offers an excellent balance of size, durability, and value, making it the best overall choice. Those seeking the best long-term investment and superior insulation might prefer the In The Swim 12 Mil Premium Blue Round Cover for its enhanced heat retention. Beginners or casual users could opt for lighter, easier-to-handle options like the Intex Solar Pool Cover for 18ft Round. Pool owners with larger or irregular-shaped pools should focus on custom-fit or larger coverage options like the VINGLI 18×36 ft Solar Pool Cover. Ultimately, selecting the right cover depends on your pool size, usage frequency, and handling preferences, but these picks provide a solid starting point for 2026.
