Key Takeaways
- Thicker covers (16 mil) generally retain heat better but tend to be more expensive and less flexible.
- Larger covers like 20×40 ft models are ideal for bigger inground pools but may be heavier to handle.
- Bubble covers with multiple layers typically improve heat retention and reduce evaporation more effectively than single-layer options.
- Durability varies significantly—heavy-duty options last longer but come at a higher upfront cost.
- Size precision matters—oversized covers can be cut to fit, but miscalculations may lead to waste and added expense.

More Details on Our Top Picks
In The Swim 20′ x 40′ Premium Blue Rectangle Solar Pool Cover 12 Mil
This heavy-duty 12-mil cover stands out for its exceptional durability and ability to retain heat, making it a reliable choice for those prioritizing long-term performance. Unlike thinner options like the VEVOR 16 Mil, this cover is built to withstand seasonal wear, though it requires manual trimming to fit your pool shape, which can be less convenient. While it helps lower chemical and water evaporation, its limited UV resistance info may impact longevity in intense sun. The solid polyethylene material and heavy-duty construction make it suitable for owners who want a long-lasting solution that can be customized for a precise fit.
Pros:- Exceptional durability for seasonal use
- Helps reduce chemical and water evaporation
- Easy to cut for custom fit
Cons:- Requires manual trimming for perfect fit
- Limited info on UV resistance and long-term sun exposure

- Size:20′ x 40′
- Material:Polyethylene
- Thickness:12 Mil
- Color:Blue
Our verdict“This cover suits owners who need a tough, customizable option and are willing to handle trimming and installation.”
VEVOR Solar Pool Cover, 24 x 12 ft Rectangle, 16 mil Bubble Solar Blanket for Pools, Inground and Above Ground, Blue
Compared with the larger but thinner VEVOR 36 x 18 ft cover, this 24 x 12 ft model offers a versatile size with a thicker 16-mil bubble design that enhances heat retention and reduces evaporation effectively. It’s a solid option for owners with rectangular pools who want a balance between durability and affordability. While it can be cut to fit various shapes, it shares the same trimming inconvenience as other covers, and its limited shape options might not suit irregular pools. Its tear-resistant PE material ensures longevity in sun exposure, making it a practical choice for budget-conscious owners who want reliable performance without the premium price.
Pros:- Thicker 16-mil material for durability
- Reduces evaporation and heats water efficiently
- Flexible size with cut-to-fit customization
Cons:- Requires manual cutting for fit
- Limited to rectangular shapes, less suited for irregular pools
Best for: Homeowners with rectangular pools seeking a durable, cost-effective cover that extends swimming seasons

- Size:24 x 12 ft
- Thickness:16 Mil
- Material:PE (Polyethylene)
- Color:Blue
- Application:Inground and Above Ground
Our verdict“This cover offers strong value for pool owners who need a durable, versatile option at an affordable price.”
VEVOR Solar Pool Cover 40 x 20 ft, 16 Mil Rectangle Solar Blanket Blue
Compared with smaller covers like the 24 x 12 ft VEVOR, this 40 x 20 ft option provides expansive coverage ideal for large inground pools that need consistent heat retention. Its 16-mil bubble design offers excellent insulation, helping extend the swimming season even in colder climates. However, the size means it requires more effort to cut and handle, and precise fitting can be challenging without careful measurement. Its sun-resistant PE material ensures durability, but the sheer size might be cumbersome for owners with limited storage space. This pick is best for those with large pools who want maximum coverage and heat retention.
Pros:- Generous size for large pools
- Excellent heat retention and evaporation reduction
- Durable, sun-resistant PE material
Cons:- Difficult to handle and cut due to large size
- Requires precision for custom fit

- Size:40 x 20 ft
- Thickness:16 Mil
- Material:PE (Polyethylene)
- Color:Blue
Our verdict“This cover is ideal for owners of large pools who prioritize maximum heat retention and seasonal extension, despite handling challenges.”
Blue Wave 16×32-ft Rectangle Solar Pool Cover 12-Mil Blue
Offering a practical size of 16 x 32 ft and a 12-mil thickness, this cover balances affordability with effective heat retention via thermal bubble technology. It compares favorably to the thicker 16 Mil covers like VEVOR’s 40 x 20 ft, but with slightly less insulation power. Its compatibility with both above-ground and inground pools makes it a flexible choice, although trimming is necessary for a perfect fit, which may be tricky for some owners. The thermal bubbles effectively absorb and transfer solar energy, making it suitable for owners seeking a reliable, budget-friendly option that can be adapted to various pool shapes.
Pros:- Good balance of cost and performance
- Fits both above-ground and inground pools
- Thermal bubble technology enhances heating efficiency
Cons:- Requires trimming, which can be challenging
- Less effective in very cold or cloudy conditions

Not ideal for: Owners with irregular-shaped pools or those who need maximum insulation in cold climates
- Size:16 x 32 ft
- Thickness:12 Mil
- Material:Thermal Bubble PE
- Color:Blue
Our verdict“This cover makes sense for owners seeking a versatile, affordable option that balances performance and ease of use.”
Solar Pool Cover 12 x 24 ft Blue Bubble Heating Blanket 12 Mil
This 12 x 24 ft cover offers a compact size with 12-mil thickness, making it a practical choice for owners with smaller or medium-sized pools. Its thermal bubble design efficiently captures solar energy to raise water temperature by up to 15°F, similar to larger, more expensive covers like the 40 x 20 ft VEVOR. While it’s easy to trim and handle, its size limits coverage for larger pools, and its effectiveness depends heavily on sun exposure. This pick is well-suited for those on a budget who want a straightforward, reliable solar heating solution for moderate-sized pools.
Pros:- Efficient solar heating for smaller pools
- Heavy-duty 12-mil thickness for durability
- Easy to trim for a custom fit
Cons:- Limited coverage area for larger pools
- Effectiveness varies with sun exposure
Best for: Owners of small to medium pools seeking an affordable, effective solar cover
Not ideal for: Large pool owners or those in heavily shaded locations needing maximum coverage
- Size:12 x 24 ft
- Thickness:12 Mil
- Material:Polyethylene
- Color:Blue
Our verdict“This cover is a solid option for smaller pools where budget and simplicity are priorities, despite size limitations.”
VEVOR Solar Pool Cover, 36 x 18 ft Rectangle Bubble Cover, 8 Mil Pool Solar Blanket with Bubble & PE Material
This VEVOR 36 x 18 ft cover stands out for its generous size and effective heat retention, making it a flexible choice for many inground pools. Compared with the thicker 16 mil options, its 8 mil thickness offers adequate insulation while remaining lightweight and easy to handle. Its durable PE material resists weather damage but isn’t ideal for highly chlorinated or acidic environments, which could accelerate wear. The larger size and universal fit make it suitable for various pool shapes, though some trimming might be needed for irregular pools. Its main strength lies in balancing affordability, durability, and coverage, but it sacrifices some longevity compared to thicker, more robust covers.
Pros:- Effective heat retention and solar absorption
- Durable and weather-resistant PE material
- Reduces water evaporation by up to 95%
Cons:- Not recommended for highly chlorinated or acidic environments
- May require trimming for irregular pool shapes

- Size:36 x 18 ft
- Material:PE
- Thickness:8 Mil
- Color:Blue
- Suitable for:Inground & Above Ground Pools
Our verdict“This cover suits owners who want broad coverage and durability at an accessible price, accepting some trimming and environmental limitations.”
VEVOR Solar Pool Cover 32 x 16 ft, 16 Mil Rectangle Solar Blanket Blue
This VEVOR 32 x 16 ft cover excels at extending swimming seasons thanks to its 16 mil thickness, which provides superior heat retention compared to thinner options like the 12 mil cover from In The Swim. Its high durability against sun exposure and weather makes it ideal for long-term outdoor use, but it requires careful handling due to its weight and size, especially when trimming to fit irregular pools. The thicker material also means it’s less prone to tears, offering a longer lifespan. Unlike thinner covers, it may be more cumbersome to manage, yet it offers the best balance between heat retention and durability for owners willing to handle a heavier product.
Pros:- Extends swimming season by increasing water temperature
- Resistant to sun exposure and harsh weather
- Thicker 16 mil material offers increased durability
Cons:- Requires cutting for irregular shapes
- Potentially heavy and difficult to handle
Best for: Pool owners looking for maximum durability and extended heat retention over a long swimming season

- Size:32 x 16 ft
- Thickness:16 Mil
- Color:Blue
- Material:PE
Our verdict“This cover is ideal for those prioritizing longevity and thermal efficiency, even if it demands more effort to manage.”
BigXwell Heavy-Duty Solar Pool Cover 16x32ft – 16Mil Blue
The BigXwell 16×32 ft cover offers a solid option for those who want to warm their pool efficiently while maintaining ease of use. Its 16 mil thickness provides a good balance between durability and flexibility, similar to the VEVOR 16 mil cover, but with a more manageable size for trimming. The thermal bubbles trap heat effectively, helping to maintain warmer water temperatures during cloudy days. However, its performance still depends on sunlight exposure, and in harsh weather, wear may accelerate. Compared to the smaller 16 mil covers, its larger size allows for fewer seams and better coverage, but it still requires trimming for irregular pool shapes.
Pros:- Effective heat retention through thermal bubbles
- Durable 16 mil PE material
- Easy to cut and customize for various pool shapes
Cons:- Performance depends on sunlight and weather conditions
- Potential wear over time in harsh environments
Best for: Owners needing a durable, heat-trapping cover that’s easy to customize for their pool size
Not ideal for: Those seeking a lightweight, super-easy-to-handle cover for quick installation and removal
- Size:16×32 ft
- Mil Thickness:16 Mil
- Material:PE
- Color:Blue
Our verdict“This cover suits owners who prioritize durability and thermal efficiency with flexible fitting, accepting some weather-related wear risks.”
In The Swim 18′ x 36′ Premium Blue Rectangle Solar Pool Cover 12 Mil
This In The Swim 12 mil cover offers a robust option for long-term pool care, with a thick and tear-resistant design that helps retain heat effectively. Its heavy-duty polyethylene material makes it more cumbersome to handle, especially when trimming, but it promises a longer lifespan compared to thinner covers. Designed for larger pools, the 18 x 36 ft size provides good coverage and reduces water and chemical use, which appeals to environmentally conscious owners. While its weight may deter quick setup, its durability and ability to extend swimming seasons make it a standout for serious pool owners willing to invest effort in installation.
Pros:- Helps retain heat and extend swimming season

- Thickness:12 Mil
- Material:Polyethylene
- Color:Blue
- Warranty:7 Years
Our verdict“This heavy-duty cover is best for owners seeking durability and resource savings, despite handling challenges.”
VEVOR Solar Pool Cover 32 x 16 ft 16 Mil Pool Bubble Cover Blue & Black
This VEVOR 32 x 16 ft cover features a dual-color design—blue and black—that enhances heat absorption by maximizing sunlight exposure. Its 16 mil thickness offers effective thermal retention similar to other 16 mil covers but with the added benefit of the color contrast, which can absorb more heat in different conditions.

This BigXwell cover stands out for its balanced 16 mil thickness combined with a generous 12×24 ft size, making it a versatile choice for both inground and above ground pools. Compared with larger options like the BigXwell 20×40 ft, it offers easier handling and storage without sacrificing heating efficiency. Its lightweight design simplifies installation, and the thermal bubbles effectively trap heat, extending your swimming season. However, its durability can vary depending on weather exposure, and it might require trimming for irregular pool shapes, which adds a minor inconvenience.

- Thickness:16 mil
- Material:Polyethylene
- Color:Blue
- Application:Inground & Above Ground Pools
- Bubble Thickness:Thermal bubbles
Our verdict“This cover offers a well-rounded solution for pool owners wanting simplicity and reliable heat retention with moderate weather resistance.”
Real Relax 16 mil Solar Pool Cover, 16 x 32 ft Rectangle Bubble Blanket
Compared with the BigXwell 12×24 ft, the Real Relax 16 mil cover offers a larger 16×32 ft size, making it ideal for bigger pools or those needing a bit more coverage. Its 16 mil thickness ensures durability and efficient heat retention, helping reduce heating costs and extend your swim season. The ability to trim the cover allows a tailored fit, which is an advantage over pre-sized options, but it also means manual work is required for proper sizing. Its bubble side faces down, which can lead to deflation over time. This cover suits pool owners who want a customizable, cost-effective way to retain heat without the bulk of larger models like the Sun2Solar 18×36 ft, but those seeking a maintenance-free product may find it less appealing.
Pros:- Helps retain heat and reduce heating costs
- Prevents debris and leaves from entering the pool
- Easily trimmed for a custom fit
- Reduces water evaporation by up to 95%
Cons:- Requires manual trimming for proper fit
- Durability depends on handling and storage

Best for: Owners of larger or irregularly shaped pools who are comfortable trimming and customizing their cover for optimal fit and performance.
Not ideal for: Users preferring a ready-to-use, no-trim solution or those who want a more durable, weather-resistant cover for prolonged outdoor exposure.
- Material:16 mil-thick PE
- Size:16 x 32 ft
- Shape:Rectangle
- Bubble Side:Down
Our verdict“This cover is best suited for pool owners seeking a customizable, budget-friendly heating solution that can be tailored to their specific pool shape.”
Sun2Solar Solar Pool Cover 16 Mil 18 x 36 Ft Blue
The Sun2Solar 18×36 ft cover stands out for its thick 16 mil resin material, providing a strong barrier against UV damage and wear over multiple seasons. It excels at raising water temperature by up to 15°F, making it a solid choice for extending your swimming season without additional energy costs. Compared to the VEVOR 24×12 ft, which is more suited for smaller or above-ground pools, this larger rectangular cover offers flexible fit options for various inground pool sizes. Its durability comes at a slightly higher price point, and proper placement is essential to maximize heat retention. This cover is ideal for those prioritizing longevity and maximum heat gain, but users with irregular or non-rectangular pools may find it less adaptable without trimming.
Pros:- Raises pool temperature by up to 15°F
- Reduces water evaporation by up to 95%
- Durable resin material resists warping and fading
- Suitable for extended seasonal use
Cons:- Requires proper placement for optimal heat retention
- May need replacement after several seasons

Best for: Inground pool owners wanting a durable, large cover that significantly boosts water temperature and lasts multiple seasons.
Not ideal for: Pool owners with irregularly shaped pools or limited budget, since larger sizes and thicker material tend to be more costly and less adaptable without modifications.
- Size:18′ x 36′
- Thickness:16 mil
- Material:Resin
- Shape:Rectangular
- Color:Blue
- UPC:840304218387
Our verdict“This heavy-duty cover is best for owners seeking a long-lasting, high-performance solution for larger inground pools aiming to extend their swimming season.”
VINGLI 18x36ft Solar Pool Cover 12mil Rectangle Blue
The VINGLI 18×36 ft cover offers a 12 mil thickness, slightly thinner than other options, but compensates with welded seams and heavy-duty construction that withstands frequent handling. Its ability to be cut to fit irregularly shaped pools makes it a flexible choice compared to fixed-size covers like the BigXwell 20×40 ft. The bubble side faces down during use, which some may see as a drawback, since it can appear deflated, but this does not reduce its heat retention capability. Its compatibility with VINGLI’s pool cover reel enhances ease of use, making handling less cumbersome. This pick is ideal for pool owners who need a durable, customizable cover that can adapt to non-rectangular shapes, but those seeking a thicker, more insulating layer might prefer 16 mil options for better heat retention.
Pros:- Extends swimming season by retaining heat
- Reduces evaporation and debris entry
- Easy to cut and customize for various shapes
- Heavy-duty welded seams for durability
Cons:- Bubble side is down, may appear deflated
- Requires pool cover reel for best handling
- Thinner 12 mil material offers slightly less insulation
Best for: Owners of irregular or complex-shaped pools needing a heavy-duty, customizable cover that pairs with their reel for easy handling.
Not ideal for: Those wanting a thicker, more insulating cover or a simple, ready-to-use product for straightforward rectangular pools, as the 12 mil thickness offers less thermal efficiency.
- Size:18×36 ft
- Thickness:12 mil
- Material:Heavy-duty, welded seams
- Shape:Rectangle
Our verdict“This cover is best suited for pool owners who need a tough, customizable option capable of fitting complex shapes and enduring outdoor conditions.”
BigXwell Heavy-Duty Solar Pool Cover 20x40ft – 16Mil Blue
The BigXwell 20×40 ft cover offers ample coverage for large inground pools, with a sturdy 16 mil thickness that balances durability with heat retention. Its size makes it ideal for owners with big pools who want a straightforward, no-fuss solution to extend swimming seasons and reduce energy costs. It performs similarly to the Sun2Solar 18×36 ft but provides more area coverage, which can be advantageous for larger pools. However, this size and thickness mean it’s less manageable for smaller or irregular pools, and it may require more storage space. This product suits owners prioritizing maximum coverage and heat efficiency for sizable pools, but it might be overkill for smaller or maintenance-sensitive setups.
Pros:- Effectively heats large pools using sunlight
- Reduces evaporation and chemical loss
- Durable, weather-resistant construction
- Easy to install and handle with proper equipment
Cons:- Requires ample space for storage and handling
- May need replacement after prolonged exposure
- Size may be too large for smaller pools
Best for: Large inground pool owners seeking a robust, high-capacity cover to maximize solar heating and minimize evaporation across extensive surface areas.
Not ideal for: Owners of small or irregular pools who might find the large size cumbersome or unnecessary, or those with limited storage space.
- Size:20×40 ft
- Thickness:16 Mil
- Color:Blue
Our verdict“This large, heavy-duty cover is perfect for owners of big pools looking to maximize solar heating with minimal maintenance effort, provided they can handle the size.”
How We Picked
Products were evaluated based on their size range, material thickness (mil), construction quality, and customer feedback on durability. Performance in heat retention and ease of use were key criteria, along with value for the price. We prioritized covers that are designed specifically for inground pools, ensuring proper fit and effectiveness. The ranking reflects a balance between affordability, longevity, and usability, giving buyers options across different needs and budgets.Factors to Consider When Choosing Solar Pool Cover For Inground Pools
Selecting the right solar pool cover involves understanding several key factors that influence performance and longevity. While size is obvious, material thickness, bubble structure, and material durability play critical roles. Beyond these, consider ease of installation, UV resistance, and whether the cover is designed for in-ground pools specifically. Making an informed choice means weighing these factors against your pool’s size, climate, and maintenance preferences. Avoid common mistakes like choosing too thin a cover or one that’s incompatible with your pool dimensions, which can lead to poor performance or early replacement.Size and Fit
The most important consideration is choosing a cover that precisely fits your inground pool. Oversized covers can be trimmed, but undersized ones leave gaps that reduce efficiency. Measure your pool carefully and compare with product dimensions. An ill-fitting cover can allow heat loss and evaporation, negating the benefits of solar heating. For custom or irregularly shaped pools, consider covers that can be cut or tailored to your specific dimensions, though this may require extra effort.
Material Thickness and Bubble Structure
Thickness, measured in mils, directly influences heat retention and durability. Thicker options, such as 16 mil, tend to hold heat better and resist tears, but they may be less flexible and harder to handle. Bubble structure also matters; multi-layer bubbles improve insulation and reduce evaporation more effectively than single-layer designs. Balancing thickness with ease of handling is key—thicker covers last longer but may require two people for installation.
Durability and UV Resistance
Since solar covers are exposed to sunlight daily, UV resistance is vital for prolonged lifespan. Poor-quality covers degrade faster, becoming brittle and prone to tears. Investing in UV-resistant materials can extend the life of your cover significantly, especially in sunny climates. Heavy-duty options offer superior longevity but come at higher initial costs. Consider how much wear and tear your pool’s environment typically produces when choosing between standard and heavy-duty covers.
Ease of Use and Handling
Handles, weight, and flexibility influence how easily a cover can be installed or removed. Heavier, thicker covers tend to be sturdier but more challenging to manage without assistance. Features like built-in handles or lightweight designs can make routine use more manageable, especially if you need to cover and uncover your pool frequently. For smaller or less physically capable users, choosing a lighter, more manageable cover can improve overall satisfaction.
Cost and Longevity
While cheaper covers might seem attractive initially, they often require replacement sooner, reducing overall value. More durable, thicker covers tend to cost more upfront but last longer and perform better over time. Consider your budget and how long you expect the cover to serve you. If you live in a climate with intense sun exposure, investing in a higher-quality, UV-resistant model can save money in the long run by reducing replacement frequency.
Frequently Asked Questions
How do I size a solar pool cover for my inground pool?
To size a solar pool cover correctly, measure the length and width of your pool at the water surface, then add a few extra inches on each side to ensure coverage of the entire surface. Many manufacturers offer standard sizes, but for irregularly shaped pools, you might need to cut a larger cover to fit. Accurate measurements prevent heat loss and evaporation, maximizing the cover’s effectiveness. Keep in mind that slightly oversized covers are easier to trim down than undersized ones, which won’t provide full coverage.
Are thicker solar covers always better?
Generally, thicker covers—such as 16 mil—offer better insulation and durability, but they can be heavier and more difficult to handle. Thinner options, like 12 mil, are easier to manage and lighter but may degrade faster and provide less heat retention. The choice depends on your balance between ease of use and longevity. For larger, heavily used pools, investing in a thicker, more durable cover can be worthwhile, whereas smaller or less frequently used pools might do well with a thinner, more affordable option.
How long will a typical solar pool cover last?
The lifespan of a solar pool cover varies based on material quality, climate, and usage. Most standard covers last 3-5 years, while heavy-duty UV-resistant models can extend to 5-7 years or more. Proper maintenance, like rinsing off debris and avoiding sharp objects, can significantly prolong its life. If you live in a sunny, hot climate, UV degradation occurs faster, making higher-grade, UV-resistant options a better investment for longevity.
Can I cut or modify a solar cover for my pool?
Many solar covers are designed to be cut to fit irregularly shaped pools or specific sizes. Using sharp scissors, you can trim the excess material, but it’s important to measure carefully beforehand. Manufacturers often provide guidelines or templates for cutting. Cutting a cover can help maximize coverage and efficiency, but it’s best to do so carefully to avoid uneven edges that may cause tears or reduce insulation performance.
How does a solar cover improve my pool’s heating efficiency?
A solar pool cover traps heat from sunlight and reduces evaporation, which is a major source of heat loss. By creating a barrier over the pool surface, it helps maintain higher water temperatures overnight and during cloudy days. Bubble structures enhance insulation by trapping air, which acts as a natural insulator. Properly fitted and thicker covers tend to perform better, translating into warmer water and less energy needed for heating, especially in cooler months.
