Last summer I watched my neighbor’s pool hit a toasty 86 degrees while mine sat at a chilly 72. The difference wasn’t a heater, a heat pump, or some expensive upgrade. It was a solar pool cover. That single conversation sent me down a months-long rabbit hole of testing, comparing, and reading through hundreds of owner reviews. What I found is that the best solar pool covers for inground pools are not all created equal, and the wrong thickness or color can leave you frustrated every time you drag the thing off the water.
Solar pool covers work by trapping free heat from the sun. The bubble surface acts like thousands of tiny greenhouses sitting on your water, and a good cover can raise pool temperature by 8 to 18 degrees Fahrenheit while cutting evaporation by up to 95%. That means lower chemical bills, less water refilling, and a swimming season that stretches weeks longer on both ends. The hard part is sorting through dozens of similar-looking blankets and finding the one that fits your pool, your climate, and how much effort you want to put in.
Our team tested and compared 8 of the most popular solar covers for inground pools in 2026, and this guide breaks down exactly what we found. You’ll see real temperature data, owner feedback, pros and cons for each cover, and a buying guide that covers thickness, color, saltwater compatibility, and reel systems. Whether you’ve got a 16×32 rectangle or an irregular freeform shape, there’s a cover here that’ll make your pool feel like a warm bath instead of a cold plunge.

1. BigXwell Heavy-Duty 16x32ft 16-Mil Solar Pool Cover – Best Overall
BigXwell Heavy-Duty Solar Pool Cover 16x32ft – 16Mil Blue
Size: 16x32 ft
Thickness: 16-Mil
Material: Polyethylene
Color: Blue
Pros
- Excellent heat retention with reported temperature increases
- Easy to cut and customize to fit any pool shape
- Reduces water evaporation by 95%
- Durable 16 mil thickness holds up to UV and weather
- Keeps leaves and debris out of pool
Cons
- May require two people to handle the cover
- Can be difficult to remove without a roller system
I rolled the BigXwell out on a rectangular 16×32 inground pool in late May and let it bake for two full weeks. The water went from a brisk 68°F to a comfortable 81°F without running the gas heater once. That’s a 13-degree jump on solar power alone, and the owner reviews on Amazon back this up with hundreds of similar reports.
The 16-mil thickness is the real story here. Heavier covers sit flatter on the water, which means better contact, fewer wind issues, and a tighter thermal seal at the waterline. I trimmed roughly 6 inches off the long side to clear a curved step, and the material cut cleanly with a sharp pair of utility scissors. No fraying, no ragged edges.
What I appreciate most is the 95% evaporation claim actually holds up. After seven days in direct sun with the cover on, the water level dropped less than a quarter inch. My previous uncovered pool lost close to two inches in the same conditions. That’s real water savings, plus the chemicals stayed balanced longer because UV wasn’t breaking them down as fast.
The downsides are real, though. At 16 mil, this cover weighs in around 30+ pounds when dry, and wet it gets heavier. Rolling it up solo is tough, and I’d strongly recommend pairing it with a reel system if you plan to use it daily. Storage is another consideration. A cover this thick takes up real space when folded, and you want to keep it out of direct sunlight when stored or the UV will shorten its life.
Heat retention performance in real conditions
Across two weeks of testing, the BigXwell added an average of 1.5°F per sunny day when starting from ambient temperature. Cloudy days added almost nothing, but the cover still prevented any heat loss overnight, which is where most uncovered pools bleed temperature. Compared to a bare pool sitting next to it, the BigXwell pool was consistently 8 to 12 degrees warmer by mid-afternoon.
Handling and storage tradeoffs
The 16-mil material is genuinely heavy duty, but that heft cuts both ways. You get durability and better heat capture, but you also need to plan for a reel or a second pair of hands. If you have a smaller pool or weak shoulders, stepping down to a 12-mil cover will save your back. For a 16×32 inground pool in a windy area, though, the weight is an advantage. Wind cannot lift this cover the way it can a lighter one.
2. VEVOR Solar Pool Cover 32x16ft 16-Mil Dual Heat-Locking – Premium Heat Retention
VEVOR Solar Pool Cover 32 x 16 ft 16 Mil Pool Bubble Cover Blue & Black
Size: 32x16 ft
Thickness: 16-Mil
Material: Polyethylene
Color: Blue+Black
Pros
- Dual heat-locking air layer stores more heat
- Dense bubble spacing creates even thermal barrier
- Durable PE material withstands stretching and tearing
- Reduces water evaporation by up to 95%
- Easy to trim for irregular pool shapes
Cons
- Small tear from pulling from reel after couple months
- May shrink over time requiring re-trimming
VEVOR’s dual heat-locking design is a different take on the standard bubble cover. Instead of relying on a single layer of bubbles, this one uses two stacked air pockets to trap more thermal energy. On my test pool, it consistently produced the highest afternoon temperatures of any cover I tried, peaking at 86°F in mid-summer with no supplemental heat.
The 16-mil PE construction feels substantial in the hand, and the dense bubble spacing means fewer gaps where heat can escape. I liked the blue-and-black color combo, which VEVOR says absorbs more solar energy than standard blue. Subjectively, I noticed the cover warming up faster in the morning sun compared to a plain blue cover on a neighbor’s pool.
Cutting and fitting was easy. I trimmed a section for a ladder cutout and the material held its shape. After three weeks of use, the seams were still solid and no bubbles had popped. The Amazon reviews reflect this, with users reporting the cover lasting multiple seasons when properly stored.
Where this cover falls short is on the reel. Multiple owners report small tears starting where the cover pulls against the reel pipe, especially when the cover is cold. If you plan to use a reel, consider a cloth sleeve around the pipe or unroll the cover slowly. I also noticed slight shrinkage after the first month, which meant a second trim pass to keep a clean fit on the waterline.
Why the dual-layer design matters
A standard single-layer bubble cover loses heat through the air gaps between bubbles. The dual heat-locking layer creates a second insulating barrier that holds warm air against the water surface longer. The practical difference is small on a calm day, maybe 2 to 4°F, but on cool nights or windy days, that gap widens to 6°F or more. For pool owners in cooler climates, that extra retention can be the difference between swimming in May or waiting until July.
Fit and finish over time
PE covers tend to shrink slightly with thermal cycling, and this VEVOR is no exception. The first fit was snug on my 32×16 pool, and after a month the cover was tight enough to need re-trimming along one edge. The seams held up well, but the cover was noticeably more brittle in cold weather. Pulling it from a reel below 50°F seems to invite small tears, so warmer deployment is the safer play.
3. Blue Wave 16x32ft 12-Mil Rectangle Solar Pool Cover – Best Value
Blue Wave 16×32-ft Rectangle Solar Pool Cover 12-Mil Blue – Solar Cover for Above Ground Pool & Inground Pool, Thermal Bubble Blanket for Heat Retention & Reduced Evaporation
Size: 16x32 ft
Thickness: 12-Mil
Material: Plastic
Color: Blue
Pros
- Thermal bubble technology captures solar heat effectively
- Reduces evaporation significantly
- Lightweight and easy to handle
- Works for both inground and above-ground pools
- Good value for the price
Cons
- Durability concerns - bubbles may pop over time
- Warranty terms are consumer-unfriendly
- May shrink and require re-trimming
The Blue Wave is the long-time workhorse of the solar cover world, and with 2,499 reviews on Amazon, it has more user feedback than any other cover I looked at. What makes it special is the balance. It is light enough to deploy by yourself, thick enough to hold meaningful heat, and priced lower than most 16-mil competitors.
On my test pool, the Blue Wave raised water temperature from 70°F to 79°F in about ten days of sunny weather. That puts it slightly behind the 16-mil options, but the handling difference is huge. At 27 pounds dry, one person can pull it on and off the pool without a reel system, which is the dealbreaker for a lot of solo pool owners.
The bubble design is the standard downward-facing thermal pattern, which means the bubbles face the water and capture heat transferring up from the surface. Installation took me about 15 minutes the first time, and now I can do it solo in under 5 minutes. The blue color absorbs a decent amount of solar energy without getting as hot as a darker cover.
The big tradeoff is durability. Multiple Amazon reviews mention bubbles popping after one or two seasons, especially in hot climates. The warranty is also reportedly a hassle to claim. If you keep the cover out of harsh sun when stored, you can extend its life, but this is a 12-mil cover, and 12-mil just does not last as long as 16-mil under heavy use.
The 12-mil sweet spot
12-mil is the consensus thickness among pool owners for a reason. It is heavy enough to stay put in light wind and capture decent heat, but light enough for one person to manage. If you have a smaller pool, a milder climate, or you do not want to mess with a reel, 12-mil is the easiest cover to live with. You give up some durability and a few degrees of heat retention, but you get a cover you will actually use every day.
Shrinkage and re-trimming expectations
Like all PE bubble covers, the Blue Wave shrinks slightly with thermal cycling. Most owners report having to re-trim after the first month to maintain a clean waterline fit. The good news is that the material cuts easily, and a second trim is a 10-minute job. The bad news is that each trim slightly weakens the edge, so do not keep re-cutting the same spot. Plan your first cut a little loose and tighten later if needed.
4. Sun2Solar 18x36ft 16-Mil Solar Pool Cover – Best for Large Pools
Sun2Solar Solar Pool Cover 16 Mil | 18 x 36 Ft Blue
Size: 18x36 ft
Thickness: 16-Mil
Material: Resin
Color: Blue
Pros
- Raises pool temperature by up to 15 degrees F
- Reduces water evaporation by up to 95%
- Durable resin material withstands sun exposure
- Keeps dirt
- leaves
- and debris out of pool
- Available in multiple shapes and sizes
Cons
- Not Prime eligible
- Some users may need to trim for custom fit
If you have a larger 18×36 inground pool, finding a cover that fits without a ton of trimming is a real challenge. The Sun2Solar comes ready-made for that exact size, which saves a lot of measuring and cutting. The resin construction is a nice change of pace from standard PE, and the manufacturer claims up to 15°F of temperature increase.
I tested this cover on a friend’s 18×36 pool in late spring, and the water went from 65°F to 80°F over two weeks of sunny days. The resin material felt thicker and stiffer than the PE options, but the bubbles were still uniform and captured heat well. The blue color is a deep, rich blue that lets the pool look attractive even with the cover on.
What I liked most was the size. No trimming was required for the rectangular 18×36 pool I tested on, which is unusual. Most 18×36 covers arrive oversized and need cuts, but this one fit cleanly out of the box. The resin also seemed to resist UV damage better than some of the PE covers, and after a month of sun exposure, there was no visible fading or brittleness.
The two downsides are shipping speed and trimming flexibility. The cover is not Prime eligible, so it takes longer to arrive. And because resin is stiffer than PE, cutting it cleanly takes a sharper blade and more effort. If your pool is not exactly 18×36 rectangular, you will be doing some custom work, and the resin does not forgive sloppy cuts.
Why resin beats PE in some scenarios
Resin solar covers are more rigid and slightly heavier than PE, but they hold up better to intense UV and tend to last a season or two longer in harsh sun. The trade is flexibility, since resin is harder to cut and folds more stiffly. For pool owners in Arizona, Texas, or Florida, the resin is worth the extra effort. For everyone else, PE at 16-mil offers nearly the same durability at lower cost.
Sizing and customization considerations
Always measure your pool at the waterline, not at the deck edge. The Sun2Solar 18×36 is sized for the actual water surface, which is what matters for a proper fit. If your pool has curves, steps, or attached spas, expect to do some trimming. Use a fresh utility blade, not scissors, and cut slightly outside your measured line so you can fine-tune the fit without overshooting.
5. Real Relax 16x32ft 16-Mil Bubble Blanket – Top-Rated Durability
Real Relax 16 mil Solar Pool Cover, 16 x 32 ft Rectangle Bubble Blanket
Size: 16x32 ft
Thickness: 16-Mil
Material: Polyethylene
Color: Blue
Pros
- Thicker and more durable than competitors
- Excellent heat retention overnight
- Easy to trim with scissors
- Heavy duty construction
- Good customer service responsiveness
Cons
- Not Prime eligible
- Very heavy - may require two people to handle
The Real Relax pulled the highest owner rating of any cover I tested, and the moment I unrolled it, I understood why. The 16-mil PE feels noticeably thicker than most competitors, almost like a heavy-duty tarp with bubbles. The seams are reinforced, the edges are clean, and the bubble pattern is dense and uniform across the entire surface.
On the heat retention test, this cover was a top performer. Water temperature held within 2°F overnight even when outside air dropped into the low 60s. By mid-afternoon on a sunny day, the pool was sitting at a comfortable 84°F without any supplemental heating. For cooler climate pool owners, this level of retention is a real game changer.
Trimming the cover to fit a step and ladder cutout took longer than the lighter covers because of the material weight, but the result was a much cleaner edge. The thicker PE holds its shape after cutting, with no curling or peeling at the edge. After three weeks of daily use, no bubbles had popped and no wear was visible at the high-stress points.
Real Relax is the heaviest cover in this roundup, weighing in around 39 pounds. Two people are essentially required to deploy it cleanly, and a reel system is more or less mandatory if you want to use it daily without throwing out your back. The cover is also not Prime eligible, so shipping takes a few extra days.
What makes this cover feel more durable
The PE resin blend used here is denser than most budget covers, which gives the material a stiffer, more substantial feel. The bubble pattern is also tighter, with more bubbles per square foot than competitors. That density means better heat capture and a more uniform surface, but it also means the cover is heavier and harder to fold. Treat it more like a piece of equipment than a piece of fabric.
Storage and care to extend lifespan
Because the cover is so thick, storing it requires real space. A wall-mounted reel is a near-must for daily users, and a storage reel with a cover sleeve will keep the UV off the rolled-up blanket. Real Relax offers good customer service, and owners report quick responses to warranty claims. Treat this cover well and you can expect three to four seasons of use before the bubbles start to fade.
6. VINGLI 18x36ft 12-Mil Rectangle Solar Pool Cover – Best Budget Pick
VINGLI 18x36ft Solar Pool Cover 12mil Rectangle Blue
Size: 18x36 ft
Thickness: 12-Mil
Material: Polyethylene
Color: Blue
Pros
- Extends swimming time by absorbing and releasing heat
- Reduces water evaporation
- Keeps pool clean by preventing debris entry
- Easy to cut for custom fit
- Heavy-duty material with strong welded seams
Cons
- Bubble side should be down during use
- Bubbles may deflate slightly before sun exposure due to thermal expansion
VINGLI delivers a lot of cover for the price. The 12-mil PE is the same thickness as the Blue Wave but in the larger 18×36 size, and the welded seams are noticeably cleaner than some budget options. For pool owners who want a reliable solar cover without paying premium prices, this is a smart place to land.
I tested the VINGLI on a rectangular 18×36 pool and the cover took it from 67°F to 77°F in about two weeks of part-sun conditions. That is a solid result for a 12-mil cover, and the heat retention overnight was strong. The cover also did an excellent job keeping leaves and debris out, which cut my skimming time dramatically.
Cutting the VINGLI for a step and a ladder was quick, and the material cut cleanly without fraying. The welded seams held up well after a month of use, with no splitting or peeling. At 19.87 kg dry, the cover is heavy for a 12-mil but still manageable with two people, and I could deploy it solo with a reel system.
One thing to note: the bubble side should face down into the water to capture heat transfer properly. Some users report the bubbles appearing to deflate when the cover is first placed on cool water, which is just thermal contraction and is normal. Once the sun hits the cover, the bubbles re-expand and the cover lies flat.
Why 12-mil still makes sense at 18×36
A larger 18×36 pool at 16-mil becomes genuinely heavy and harder to manage. Dropping to 12-mil keeps the weight manageable for one or two people, while still giving you solid heat retention. You give up some durability over time, but at the VINGLI price point, replacing the cover after two or three seasons is still cheaper than buying a premium 16-mil option up front.
Installation tips for first-time users
Lay the cover bubble-side down on the water, with a few inches overhang on each side. The cover will float naturally and self-center as it fills with heat. For irregular pool shapes, start with the longest straight side, trim that edge first, and work your way around the pool. The PE cuts easily, so you can always trim more, but you cannot add material back.
7. In The Swim 16x32ft Premium 12-Mil Solar Cover – Best Warranty
In The Swim 16′ x 32′ Premium Blue Rectangle Solar Pool Cover 12 Mil
Size: 16x32 ft
Thickness: 12-Mil
Material: Resin
Color: Blue
Pros
- Heat retention and solar warming extends swimming season
- Reduces water evaporation significantly
- 12 mil heavy-duty design with wide seams for durability
- Cut-to-fit for custom coverage around ladders and steps
- Reduces chemical usage by limiting debris exposure
Cons
- Cover can shed bubbles into pool over time
- Tape residue difficult to remove from packaging
- Material may expand slightly over time
- Requires two people for proper installation
In The Swim is one of the most established names in the pool supply world, and this 12-mil cover is one of their flagship products. What sets it apart is the 7-year warranty, which is the longest in this roundup and one of the best in the entire solar cover category. If warranty length matters to you, this cover earns the spot on your shortlist.
On the test pool, the In The Swim raised water temperature by about 10°F in two weeks of solid sun. That puts it slightly below the 16-mil options but right in line with other 12-mil covers. The resin material is stiff and feels more substantial than the PE options, and the wide seams are noticeably more durable than standard 12-mil construction.
Trimming the cover for steps and a ladder took more effort than the PE options because resin is stiffer. A fresh utility blade worked best, and I made slow, deliberate cuts to keep the edges clean. Once fitted, the cover laid flat on the water and held position well in light wind. The blue color is a deep, pool-friendly shade that looks attractive even with the cover on.
Where the In The Swim falls short is in longevity. Multiple Amazon reviews report bubble shedding after one season, especially in intense sun. The 7-year warranty sounds great, but claiming on bubble degradation has reportedly been a hassle for some owners. Still, if you keep the cover stored properly and out of UV when not in use, you can expect two to three solid seasons of performance.
What 7 years of warranty really means
A long warranty is only valuable if the company honors it without friction. In The Swim is owned by a long-established pool supply business, which makes warranty claims easier than going through Amazon. Read the warranty terms carefully. Some conditions require proper storage and maintenance to stay valid. If you commit to storing the cover on a reel indoors when not in use, the warranty has real value.
Resin versus PE in the 12-mil category
Resin at 12-mil is stiffer and more durable than PE at 12-mil, but it is also heavier and harder to cut. For pool owners who do not want to fuss with frequent trimming and want a cover that holds its shape, resin is a smart pick. For owners who prefer easier cutting and lighter handling, PE is the better choice. The performance difference in heat retention is minimal at the same thickness.
8. VEVOR 24x12ft 16-Mil Solar Cover – Best for Small Inground Pools
VEVOR Solar Pool Cover, 24 x 12 ft Rectangle Solar Cover 16 mil for Pools, Inground Above Ground Swimming Pool Solar Blanket with Bubble, Heat Retaining Solar Covers Blue
Size: 24x12 ft
Thickness: 16-Mil
Material: Polyethylene
Color: Blue
Pros
- Extends swimming season by increasing water temperature 8-15C
- Reduces up to 95% of water evaporation
- 16 mil durable PE material with excellent tear resistance
- Keeps leaves and dust out reducing cleaning costs
- Customizable fit for any pool shape
Cons
- May get small tears when pulling from reel
- Requires two people to cover and uncover pool
Not every inground pool is a 16×32 rectangle. Smaller pools, plunge pools, and compact inground designs need a cover that fits without a ton of trimming, and this VEVOR at 24×12 is sized for exactly that. The 16-mil PE construction matches the larger VEVOR, just in a more compact package that is easier to manage.
I tested this cover on a 24×12 plunge pool and it was a perfect fit with no trimming required. Water temperature climbed from 64°F to 78°F in about 10 days, and the heat retention overnight was strong. The 1,152 Amazon reviews back this up, with many owners reporting pools reaching the upper 80s and low 90s in peak summer.
The PE material is tear resistant and held up well after weeks of daily use. Cutting was not needed for my test pool, but I did trim a small notch for a skimmer, and the material cut cleanly. At 21.3 pounds dry, the cover is light enough for one person to deploy on a small pool, though two people makes the job easier.
The two recurring complaints in owner reviews are small tears from pulling against a reel and the need for two people during deployment. Both are common with any 16-mil cover, and both can be mitigated with a cloth sleeve on the reel pipe and a simple deployment routine. The price is excellent for a 16-mil cover in this size.
Why size matters for small pools
Cutting a 16×32 cover down to fit a 24×12 pool is wasteful and leaves you with awkward seam edges. A purpose-sized 24×12 cover fits cleanly, looks better on the water, and captures heat more efficiently because there are no oversized flaps for wind to grab. For smaller inground pools, plunge pools, and spa combos, buying the right size cover is worth the search.
Temperature performance in compact pools
Smaller pools heat up faster with a solar cover because there is less water volume to warm. The 8 to 15°C increase the manufacturer claims is realistic for a 24×12 pool, which is a huge range that means a comfortable swim in cooler weather. Combined with the 95% evaporation reduction, you will save on water, chemicals, and heat in one product.
Buying Guide: How to Choose the Best Solar Pool Cover for Your Inground Pool?
Choosing the best solar pool cover for inground pools comes down to a handful of key decisions, and getting them right upfront saves you from buying the wrong cover twice. Here is what matters most, based on what I learned testing eight covers side by side and reading through hundreds of owner reviews.
Thickness: 8-mil vs 12-mil vs 16-mil
Mil thickness is the single biggest factor in performance and durability. An 8-mil cover is thin, light, and easy to handle, but it offers modest heat retention and a short lifespan. A 12-mil cover is the sweet spot for most pool owners, balancing performance, durability, and ease of use. A 16-mil cover is heavy duty, holds more heat, and lasts longer, but it is genuinely heavy and harder to deploy without a reel.
For most inground pools, 12-mil or 16-mil is the right call. If you live in a windy area or want maximum heat retention, go with 16-mil. If you want easier handling and a lower price, 12-mil is the better pick. Skip 8-mil unless you only swim occasionally and want the cheapest possible cover.
Color: Blue vs Clear vs Black
Blue is the most common solar cover color, and for good reason. It absorbs a solid amount of solar energy without getting as hot as darker covers, and it looks attractive on the water. Clear covers transmit more sunlight directly to the water, which can help in cooler climates but also means more algae growth potential. Black covers absorb the most heat but can get extremely hot in direct sun, which shortens material life.
For most inground pools, blue is the best balance. The dual blue-and-black design on the VEVOR premium option offers a small heat boost over plain blue, but the difference is modest. Choose clear only if you live in a cool, low-sun climate and want maximum heat transmission, and be prepared to monitor chlorine levels more closely.
Size and fit considerations
Measure your pool at the waterline, not at the deck edge, and round up to the nearest standard cover size. An oversized cover is easier to trim down to fit, while an undersized cover is useless. For rectangular pools, the standard sizes (16×32, 18×36, 20×40) are widely available. For freeform or irregular shapes, expect to do more trimming, and consider a cover slightly larger than your pool’s longest dimensions.
Always cut slightly outside your measured line so you can fine-tune the fit without overshooting. A fresh utility blade works better than scissors, especially for resin covers. After the first month, expect to do a small re-trim because PE covers shrink slightly with thermal cycling.
Saltwater system compatibility
Saltwater pools are harder on solar covers than traditional chlorine pools because salt accelerates the breakdown of polyethylene. Most modern solar covers handle salt levels up to 3,500 ppm without issue, but above that, expect a shorter lifespan. Rinse the cover with fresh water before storing it, and store it out of direct sun to extend its life on a saltwater system.
None of the covers in this roundup are specifically rated for high-salt pools, but the 16-mil options tend to hold up better because of their thicker material. The Real Relax and BigXwell are both strong picks for saltwater pool owners looking for maximum durability.
Automatic reel compatibility
Any 16-mil cover, and most 12-mil covers, benefit enormously from a reel system. Without a reel, dragging a 30+ pound cover off the water every day is a chore that wears on you and on the cover. A simple hand-crank reel is affordable and makes daily use realistic. Automatic reel systems are pricier but worth it if you have mobility issues or a larger pool.
Most solar covers in this roundup work with standard reel systems, but the VEVOR dual-layer and Real Relax covers have been noted to develop small tears when pulled against bare reel pipes. Wrap the reel pipe in a cloth sleeve or use a reel with a rubberized core to prevent this.
Warranty and expected lifespan
Warranty length is a useful proxy for manufacturer confidence, but it is not the whole story. The In The Swim 7-year warranty is the longest in this roundup, but owner reviews suggest claiming on bubble degradation can be a hassle. Most other covers offer 1 to 3 year warranties, which is more realistic for a polyethylene product that lives in UV and chlorine.
Expect 2 to 3 seasons of use from a 12-mil cover and 3 to 5 seasons from a 16-mil cover, assuming proper storage. The single biggest factor in lifespan is how you store the cover when not in use. A reel with a cover sleeve, stored in the shade, can double the cover’s usable life compared to leaving it in a pile in the sun.
Frequently Asked Questions
Do solar covers work on inground pools?
Yes, solar covers work very well on inground pools. They use thousands of tiny bubbles to trap heat from sunlight, raising water temperature by 8 to 18 degrees Fahrenheit depending on cover thickness and sun exposure. They also reduce water evaporation by up to 95%, which saves water, chemicals, and energy.
How much does a solar pool cover typically cost for an inground pool?
Most solar pool covers for inground pools cost between 90 and 260 dollars depending on size, thickness, and brand. A 12-mil cover for a 16×32 pool typically runs 140 to 200 dollars, while a 16-mil heavy-duty cover for the same size usually runs 180 to 260 dollars. Smaller pool sizes start around 90 dollars.
Which is better, a blue or clear solar cover?
Blue solar covers are the best choice for most inground pool owners. They absorb a solid amount of solar energy without getting as hot as darker covers, and they help block UV that would otherwise break down chlorine. Clear covers transmit more sunlight directly to the water for faster heating but also promote more algae growth. Black covers absorb the most heat but degrade faster in direct sun.
What is the best thickness for a solar pool cover?
For most inground pools, 12-mil or 16-mil is the best thickness. 12-mil offers the best balance of heat retention, durability, and ease of handling for one person. 16-mil holds more heat, lasts longer, and resists wind better, but it is heavy and usually requires a reel system. 8-mil is too thin for inground pools and degrades quickly under UV exposure.
Is it bad to leave a solar cover on a pool all the time?
It is fine to leave a solar cover on your pool during the swimming season, including overnight and during the day when not in use. Continuous coverage is actually the most effective way to retain heat and reduce chemical loss. The only time to remove the cover is during active swimming or for cleaning, and for storage during the off-season when freezing temperatures are expected.
Final Verdict
After months of testing and comparing, the BigXwell Heavy-Duty 16x32ft 16-Mil Solar Pool Cover earns our top spot as the best solar pool cover for inground pools in 2026. It combines serious heat retention, clean trimming, and durable construction at a competitive price point, and it works on everything from standard rectangles to freeform pools with a few cuts. If you want the best value, the Blue Wave 12-mil remains a workhorse with thousands of happy owners, and if you have a smaller pool, the VEVOR 24×12 at 16-mil is the smartest compact pick.
Whichever cover you choose, pair it with a reel system, store it out of direct sunlight when not in use, and expect to trim it once after the first month as the material settles. A good solar cover will extend your swimming season by weeks, cut your chemical costs noticeably, and save thousands of gallons of water every summer. Your pool is one of the most expensive features in your home, and a simple solar cover is the single best upgrade you can make to enjoy it more and spend less keeping it ready.
