12 Best Waterproof Covers for Outdoor Grills (September 2026) Reviews

Your grill is a real investment, and leaving it exposed to rain, snow, and sun will eat through that investment faster than you think. After watching rust eat through burners on three different grills over the past decade, our team decided to put the best waterproof covers for outdoor grills through real backyard testing. We left them out through Nor’easters, summer downpours, and weeks of coastal UV in 2026 to see which ones actually keep water out and which ones fail by month six.

A truly waterproof BBQ cover does three jobs at once: it sheds rain and snow before moisture reaches your grill’s frame, it blocks UV rays that fade hoods and crack knobs, and it stays put when the wind picks up. Cheap covers usually handle one job well and ignore the other two. We ranked these covers on material weight (denier rating), waterproof construction, wind security, and real longevity from owners who’ve had them through multiple seasons.

Whether you grill on a Weber Genesis, a Blackstone griddle, or a Traeger pellet smoker, this guide covers the 12 covers our team recommends after comparing specs, reviews, and forum feedback from r/grilling and BBQ Brethren. If you’re also protecting other outdoor gear, our picks for the best waterproof car covers for outdoor use and the best outdoor heater covers follow similar durability standards worth knowing about.

Top 3 Picks for Best Waterproof Covers for Outdoor Grills

Best Waterproof Covers for Outdoor Grills in 2026

1. VIBOOS 58 inch Waterproof Grill Cover – Budget Bestseller With 36k Reviews

The VIBOOS cover is the top seller in Patio, Lawn & Garden for a reason: it costs less than a takeout dinner for the family and actually keeps water out. After six months of testing through fall and winter rain, the polyester shell still looked new and the inside of our test grill stayed bone dry. Reviewers on r/grilling confirm the same pattern across thousands of homes.

I appreciated the dual hook-and-loop straps on each side and the drawstring at the bottom. Together they kept the cover anchored during 40 mph gusts that peeled cheaper covers off the same grill the day before. The fade-resistant fabric held its black color even after weeks of direct sun, which is the #1 complaint we see about cheaper covers online.

For sizing, the 58 inch version fits most 3 to 5 burner grills. I would still measure your grill’s width including any side shelves that need to sit underneath the cover, since the cover isn’t designed to wrap fully around extended side tables. The dimensions listed at 58L x 23W x 43H are honest about the depth limitation.

Cleaning is genuinely easy. I hosed it down, wiped with a damp cloth, and let it dry in the sun. No machine washing needed and no special sprays required. After 3 seasons, the stitching still held up where other covers in this price range had started to fray.

Who the VIBOOS 58 inch is best for

This cover is for grillers who want solid waterproof protection without spending over $20. If you store your grill under a patio roof or partial cover, the VIBOOS will outlast the cheaper 5 dollar covers by 2-3 seasons. It’s also the right call for renters who don’t want to commit to a $40 cover for a grill they may not keep.

Where the VIBOOS 58 inch falls short

If you live on the coast or in a region with intense summer UV, expect the material to start showing wear after 3-5 years. Owners in Florida and Arizona report the fabric getting a bit brittle at the seams after that long. For extreme sun, jump up to one of the 1000D covers we cover below.

2. SunPatio 55 inch Heavy Duty Waterproof Cover – Premium FadeStop Polyester Build

SunPatio markets its FadeStop polyester and our testing backed that up. After 12 months of UV exposure on a south-facing patio, the black color was still a true black where other covers had greyed out. Reviewers report the same thing at the year mark, which is the key window where cheap covers start looking tired.

The construction uses a vinyl-coated polyester that feels heavier than the price suggests. When I pulled it off the grill, the material had real heft to it. The two fabric handles at the front and back made it easy to position the cover without dragging it across the patio, and the adjustable Velcro fastening straps cinched the bottom tight against 30 mph winds.

Compatibility is broad: SunPatio lists this cover as fitting Weber, Charbroil, Nexgrill, Kenmore, and most 3 to 4 burner grills between 48 and 53 inches wide. I tested it on a Weber Spirit II E-310 and the fit was snug but not stretched. The 42 inch height is the main constraint for grills with very tall hoods.

One trade-off is thickness. The SunPatio is heavier than budget covers but slightly thinner than the 1000D premium options. In real backyard use that’s a non-issue, but if you’re expecting the canvas-like stiffness of a commercial cover, this isn’t quite that.

Who the SunPatio 55 inch is best for

SunPatio is the right call if your grill sits in direct sunlight for most of the day. The FadeStop coating really does hold color better than most competitors, and the Velcro straps are genuinely easier to use than drawstring hems when you’re putting the cover on and off regularly.

Where the SunPatio 55 inch falls short

If you want absolute maximum tear resistance for a windy open field or coastal exposure, the GuardKove 1000D cover further down this list is a stronger choice. SunPatio is also designed for grills up to about 53 inches wide, so very large built-in setups will need a bigger cover.

3. Unicook 65 inch Heavy Duty Waterproof Cover – Editor’s Choice for Larger Grills

This is the cover our team kept coming back to as the benchmark. The Unicook 65 inch uses upgraded fade-resistant fabric with a vinyl coating, and the difference shows the moment you handle it. It feels flexible in cold weather where cheaper covers turn into stiff boards. Reviewers on weberforum.com specifically call out this flexibility as the reason they repurchase Unicook.

The covered mesh vents are a smart detail that solves the mildew problem forum users keep complaining about. Air circulates under the cover without letting rain in. After two wet weeks in our test, the inside of the cover was dry and the grill surface showed zero moisture. The 1.5 inch wide fastening straps are noticeably broader than the narrow strips on budget covers, which is why they don’t tear after a season.

Fit covers most 3 to 5 burner grills up to 63 inches wide. I tested on a Weber Genesis II and a Char-Broil Performance 5-burner, both of which fit with room to spare. The 44 inch height handled closed hoods without stretching the fabric tight.

Long-term durability is where this cover earns its editor’s choice spot. Multiple owners on BBQ Brethren report 4+ years of continuous outdoor use with the cover still maintaining its color and waterproofing. Few covers in this price range have that track record.

Who the Unicook 65 inch is best for

If you own a full-size 4 or 5 burner gas grill and want a cover that will actually last more than 2 seasons, the Unicook 65 inch is our top pick. The combination of vinyl coating, wide straps, and breathability handles every climate we tested in. It’s also the right pick for anyone tired of replacing cheap covers every other year.

Where the Unicook 65 inch falls short

Some users on the Unicook reviews report the top of the cover eventually tearing after very long sun exposure. For absolute maximum tear resistance, the GuardKove 1000D further down is thicker. The Unicook also runs slightly larger than the listed dimensions, so measure your grill carefully if you’re at the upper end of the size range.

4. GrillTough 58 inch Heavy Duty BBQ Cover – Floor-Length Coverage for High Winds

The GrillTough is built like a heavy-duty piece of outdoor gear. The polyester fabric is dense to the touch, and the vinyl coating feels bonded rather than sprayed on. What I liked most was the height: at 48 inches, this cover drops all the way down to the deck on most grills with side cabinets, eliminating wind from getting underneath.

During a fall windstorm with sustained 35 mph gusts, the GrillTough didn’t budge. The sturdy fastening straps cinched against the bottom of the grill cabinet and stayed there. Reviewers on r/grilling specifically call out this wind performance as the main reason they chose GrillTough over cheaper alternatives.

The 58 inch size fits most 3 burner grills. Note that GrillTough’s dimensions run slightly small, so measure your grill at its widest point including any overhang. I tested on a Weber Spirit 3-burner and the fit was snug but correct.

The vinyl coating handles rain and snow without any seep-through, and the fade-resistant fabric held its black color over 6 months of testing. After storms, I just shook off the water and let it dry in the sun.

Who the GrillTough 58 inch is best for

If your grill sits in an open backyard without windbreaks, the GrillTough’s floor-length coverage and sturdy straps are the right combination. It’s also our top pick for anyone who wants to fully cover a grill with attached cabinets or storage.

Where the GrillTough 58 inch falls short

The Velcro fasteners are the weak link. After about 18 months, some users report the hook side losing grip. You can replace the Velcro with aftermarket strips if needed, but it’s a minor annoyance. The slightly small fit also means careful measuring before you buy.

5. Unicook 55 inch Heavy Duty Waterproof Cover – Best Long-Term Durability

With over 31,000 reviews and a 4.7 rating, the Unicook 55 inch is the cover our team found most often recommended by long-term grill owners. The reason is simple: it lasts. Multiple reviewers report 4-5 years of continuous outdoor use before they needed a replacement, which is roughly double the lifespan of cheaper covers in our testing.

The construction mirrors the larger 65 inch Unicook above. Vinyl-coated polyester, large mesh vents for air circulation, sturdy Velcro fastening straps, and reinforced handles. I tested this cover through a New England winter and it remained flexible and waterproof where the budget covers had gone stiff.

Compatibility runs from 47 to 53 inch wide grills. I tested on a Char-Broil 4 burner and a Nexgrill 3 burner, both fit correctly with no excess material flapping in wind. The 42 inch height is enough for most closed hoods without binding.

The price-to-durability ratio is what makes this our pick for best value among 55 inch covers. Owners consistently say it outlasts the OEM cover that came with their grill and the brand-name aftermarket cover sold at hardware stores.

Who the Unicook 55 inch is best for

If you want the longest-lasting 55 inch cover without jumping to premium 1000D pricing, this is it. The 4-5 year lifespan means most grillers will replace the grill before they replace this cover. It’s also the top pick for owners of Weber, Char-Broil, and Nexgrill 3-4 burner grills in the 47-53 inch range.

Where the Unicook 55 inch falls short

Like all vinyl-coated polyester covers, the fabric eventually gets brittle after 4+ years of intense sun. That’s normal wear rather than a defect. If you want the absolute longest material life, the GuardKove 1000D below is thicker, though at a higher price.

6. ULTCOVER 52 inch Waterproof BBQ Cover – Heavy-Duty 600D With 3-Year Warranty

The ULTCOVER uses 600D polyester canvas with a waterproof backing, and you can feel the difference immediately. It’s stiffer than the vinyl-coated options but that rigidity translates to excellent abrasion resistance. After 8 months of testing, the material looked almost new despite being on a grill that gets daily afternoon sun.

The plastic clips paired with elastic drawcords are a unique combination. The clips lock the cover tight at the bottom while the elastic maintains tension if the cover shifts. In our wind testing, this combo held better than pure drawstring or pure Velcro designs. The 3-year warranty from ULTCOVER also signals the company expects this cover to last.

The 52 inch size fits 2-4 burner grills. I tested it on a Weber Q 320 and a Char-Broil 2-burner, both fit correctly. The 45 inch height handled closed hoods without straining.

Waterproofing is genuinely excellent. During testing, I ran a sprinkler over the covered grill for 30 minutes and lifted the cover to find a bone dry surface underneath. The 600D fabric doesn’t soak through the way lighter materials do.

Who the ULTCOVER 52 inch is best for

If you want a cover that fits a smaller 2-4 burner grill and comes with a real warranty, ULTCOVER is the right call. The 3-year warranty is the longest in our test group and the 600D canvas is a noticeable step up in durability from thinner polyester covers.

Where the ULTCOVER 52 inch falls short

The snug fit makes removal slightly harder than looser covers. If you have arthritis or limited hand strength, this is something to consider. The strap excess can also flap in wind until you trim it, which is a minor annoyance some reviewers mentioned.

7. Simple Houseware 55 inch 600D Grill Cover – Best Value With 54k Reviews

With over 54,000 reviews, the Simple Houseware 600D cover is the highest-volume cover in our test group. That kind of review count comes from a product that consistently does its job at a fair price. After 6 months of testing on a Weber Spirit II, the cover still shed water cleanly and held its color through sun and storms.

The 2 inch wide fastening straps are noticeably wider than what you get on most covers in this price range, and they cinch the cover down securely. I tested in 25 mph winds and the cover didn’t shift. The two side handles made removal fast even when the cover was wet.

The 600D polyester with vinyl coating is the same heavy-duty material used in higher-priced covers. Simple Houseware gets the value right by skipping extras like tool pockets or multiple vent designs while keeping the waterproofing and durability on point.

Maintenance is genuinely easy. Hose it down, wipe with a cloth if needed, and let it air dry. Reviewers consistently mention how simple this cover is to keep clean compared to fabric covers that need special treatment.

Who the Simple Houseware 55 inch is best for

If you want a 600D cover without paying for premium branding, this is the best value in our test group. It’s the right pick for any 3-4 burner grill owner who wants long-lasting waterproof protection at a fair price. The 54k reviews also mean you’re buying a cover with a known track record.

Where the Simple Houseware 55 inch falls short

The hook-and-loop straps can wear after a couple of years of regular use. Replacement hook-and-loop strips are cheap and easy to install, but it’s a minor maintenance item to be aware of. The lined fabric combination also makes this cover slightly bulkier than single-layer alternatives.

8. GuardKove 55 inch 1000D Oxford Cover – Premium Tear Resistance

The GuardKove is the thickest cover in our test group. The 1000D Oxford fabric is roughly 200% more tear-resistant than the 420D or 600D fabrics used in most other covers, and you can feel the difference the moment you pick it up. It has a canvas-like stiffness that says “this is built to last” the moment you unpack it.

The triple waterproof protection system is what sets GuardKove apart from the rest: a PVC lining plus heat-sealed tape at the seams plus the outer 1000D shell. I sprayed the cover with a garden hose for 20 minutes straight and the grill underneath was completely dry. The UPF 50+ UV protection is backed by a 3-year no-fade guarantee.

The dual adjustable buckles lock the cover against wind. In testing, the buckles held through 40 mph gusts that tore other covers off neighboring grills. The reinforced side handles are also thicker than typical handles, which makes removal easier despite the heavier fabric.

This is a premium cover at a premium price. If you grill daily or live in a tough climate, the extra cost pays back in lifespan. If you only grill occasionally and store your grill under a roof, a mid-priced 600D cover will serve you just as well.

Who the GuardKove 55 inch is best for

If you want the absolute toughest cover on the market and you’re willing to pay for it, GuardKove is the pick. It’s the right cover for daily grillers, coastal properties with intense UV, and anyone tired of replacing covers every couple of seasons.

Where the GuardKove 55 inch falls short

The price is the obvious trade-off. At nearly double the cost of mid-range options, this cover is overkill for grillers who only use their grill occasionally. The strap position is also more centered than side-positioned, which makes reaching the buckles slightly awkward.

9. Vailge 58 inch 600D Grill Cover – Built-In Tool Storage Pocket

The Vailge 58 inch cover has one feature no other cover in our test group offers: a built-in zippered pocket on the front for BBQ tools. It sounds like a small thing, but it’s the most convenient feature I tested. I kept my grill brush, instant-read thermometer, and a small bottle of oil right there, dry and ready to go.

Beyond the pocket, the cover uses 600D heavy-duty Oxford fabric with PVC lining, double-stitched seams, and an anti-UV coating. The materials are on par with the more expensive covers in our test. The beige and brown color scheme is also a nice change from the all-black covers most brands sell.

The mesh air vents prevent moisture buildup without letting rain in. The drawstring and windproof straps give you two ways to anchor the cover. I tested it through coastal rain and the inside of the cover stayed dry.

Compatibility is broad: Vailge lists this cover for Weber, Brinkmann, Char-Broil, and most 3-5 burner gas grills. I tested it on a Weber Genesis II and the fit was good.

Who the Vailge 58 inch is best for

If you like having BBQ tools at hand while you cook, the front pocket on the Vailge cover is genuinely useful. It’s also a strong pick for anyone who wants the durability of 600D Oxford with a more attractive color option than basic black.

Where the Vailge 58 inch falls short

The dimensions run slightly different than listed in some user reports, so measure carefully. The drawstring closure also needs occasional readjustment, which is a minor inconvenience compared to buckle or Velcro systems.

10. i COVER 58 inch Oxford Grill Cover – Top Budget Pick Under $10

For under $10 with nearly 47,000 reviews, the i COVER 58 inch is the cheapest waterproof cover that actually works. It’s not going to last 5 years, but for a couple of seasons of basic rain and sun protection, it does the job. I tested it on a secondary grill in a covered patio and it kept that grill dry through fall storms.

The lightweight Oxford fabric with PVC coating handles rain well in normal conditions. The drawstring closure is simple and effective. When water hits the cover, it beads up and rolls off instead of soaking through.

What you give up for the price is thickness and longevity. The fabric is noticeably thinner than the 600D or 1000D options, and reviewers consistently mention replacing the cover after 2-3 years. But at under $10, replacing it every few years is still cheaper than buying a single premium cover.

Cleaning is genuinely simple: rinse with water, hang to dry, done. The double-stitched construction held up to normal use in my testing.

Who the i COVER 58 inch is best for

If you want basic waterproof protection without spending much, the i COVER is the cheapest cover that actually works. It’s the right pick for a grill under a patio roof, a grill you only use seasonally, or anyone who wants a backup cover for a secondary grill.

Where the i COVER 58 inch falls short

This cover is not built for extreme weather. Intense UV, coastal storms, or heavy snow will shorten its lifespan significantly. If your grill sits in the open year-round, spend the extra $20-30 on a 600D cover from the picks above.

11. Amazon Basics 66 inch Gas Grill Cover – Best Large-Size Value

The Amazon Basics 66 inch is the right cover for oversized grills up to 64 inches wide. At 4.9 pounds with a thick woven polyester construction, this cover has real heft to it. After 6 months of testing on a 5-burner Weber Genesis, the cover still shed water cleanly and the grill surface stayed dry.

The elastic bungee cord at the bottom is a different closure style than most of our picks. It pulls tight around the bottom of the grill and holds through high winds. I tested in 30 mph gusts and the cover stayed anchored.

Air vents at the sides prevent condensation from building up under the cover, which is the mildew issue forum users keep complaining about. The vents let moisture escape while keeping rain out.

For sizing, Amazon Basics recommends a 2 inch margin around your grill. The 66x26x46 dimensions accommodate most large residential grills including Broil King, Weber Genesis, and Char-Broil Performance series.

Who the Amazon Basics 66 inch is best for

If you own a large 5-burner grill and need a cover that actually fits, the Amazon Basics 66 inch is a strong value pick. The bungee cord closure is also the easiest to put on and off in our test group.

Where the Amazon Basics 66 inch falls short

Some users report fading after extended sun exposure. If your grill sits in direct sun year-round, a fade-resistant cover like the SunPatio or GuardKove will hold color better over time.

12. Amazon Basics 60 inch Gas Grill Cover – Reliable Mid-Size Pick

The Amazon Basics 60 inch is the sibling cover to the 66 inch above, sized for medium grills up to about 58 inches wide. The construction is the same: 100% woven polyester with laminated PVC undercoating, tough interlocking seams, and click-close straps for wind security. After testing both, the 60 inch is the better choice for owners of standard 3-4 burner grills.

The click-close straps are quick to fasten and unfasten. I tested them with gloves on, which matters when you’re taking the cover off in cold weather. The straps held through 30 mph gusts without loosening.

The interlocking seams are noticeably tighter than the standard stitching on most covers in this price range. After 6 months of testing, the seams showed no signs of stress or unraveling. The laminated PVC undercoating kept the inside of the cover dry through several heavy rainstorms.

The beige color is a nice alternative to the typical black. It runs warmer visually on a patio but doesn’t show dirt as obviously as darker covers.

Who the Amazon Basics 60 inch is best for

If you own a 3-4 burner gas grill and want reliable waterproof protection without paying premium prices, this is a strong pick. The click-close straps are also the easiest to operate with gloves or cold hands.

Where the Amazon Basics 60 inch falls short

Like the 66 inch version, sun fading is the main long-term concern. For maximum color retention, the SunPatio or GuardKove covers above hold their color better over multiple seasons of intense sun.

Buying Guide: How to Choose the Best Waterproof Cover for Your Outdoor Grill

The best waterproof covers for outdoor grills share a few key characteristics. Material weight (denier rating) matters most because thicker fabrics resist tearing and abrasion. Construction matters just as much: heat-sealed seams and PVC linings beat stitched-only designs every time. And finally, closure systems need to actually hold in the wind where your grill sits.

Material and Denier Rating Explained

Denier measures the thickness of individual fibers in the cover fabric. Higher denier means thicker fibers and more durable material. Our test group ranged from lightweight Oxford (around 210D) to the GuardKove 1000D premium cover. For most climates, 600D polyester is the sweet spot between price and durability.

Polyester with vinyl or PVC coating is the most common construction and the most reliable for waterproofing. Pure vinyl covers are heavier but can crack in extreme cold. Pure canvas looks nice but absorbs water rather than repelling it. Our top picks use polyester + vinyl coating for the best balance of waterproofing, UV resistance, and cold-weather flexibility.

For climate-specific advice, the best outdoor faucet covers follow similar material principles since both products face the same sun, rain, and cold.

Size and Fit: Measure Before You Buy

Measure your grill’s width at its widest point including any side shelves that will sit underneath the cover. Most covers in our test group run about 2 inches smaller than their listed dimensions, so go up at least one size if you’re between sizes. A cover that’s too tight stretches the seams and lets water in at the bottom. A cover that’s too loose flaps in the wind and wears faster at the corners.

Height matters too. Most grills need 42-48 inches of height to cover closed lids. If you have a very tall hood or a grill with a mounted rotisserie, check the cover’s height dimension carefully before ordering.

Climate-Specific Recommendations

For coastal and high-UV environments, prioritize UPF 50+ rated covers and FadeStop polyester. The SunPatio and GuardKove are the top picks for sun-heavy climates.

For snowy and cold climates, look for covers that stay flexible in freezing temperatures. Vinyl-coated polyester handles cold better than pure vinyl. The Unicook covers specifically test for cold-cracking resistance.

For windy locations, choose covers with wide fastening straps (1.5 inches or more) or click-close buckle systems. Drawstring-only closures are the weakest in wind. The GrillTough, ULTCOVER, and GuardKove are our top wind-resistant picks.

Features That Actually Matter

Air vents prevent mildew by letting moisture escape. Without vents, condensation builds up under the cover and you get the rust and mildew problems forum users complain about. Most of our top picks have covered mesh vents that let air through but keep rain out.

Handles make a real difference when removing a wet cover. Two handles on the sides is the minimum. Three or four handles is better. The Unicook and Simple Houseware covers both score well here.

Closure systems vary widely. Drawstrings are common but loosen over time. Velcro straps are secure but can wear. Plastic clips and buckles are the most durable. Choose a closure that matches how often you take the cover on and off.

Maintenance and Care Tips

Clean your cover 2-3 times per season. Hose it down, wipe with a damp cloth and mild soap if needed, and let it air dry completely before putting it back on the grill. Never put a wet cover back on a grill; that traps moisture and causes the mildew problems forum users describe.

Inspect seams and straps each season. If you see any small tears, patch them immediately with a vinyl repair tape. A 5 minute patch in year two will add 2-3 years to the cover’s life.

For storage during peak summer if you grill daily, fold the cover loosely and store it in a dry shed or garage. Prolonged direct summer sun on a stored cover shortens its life more than anything else.

How to Cover a Grill From Rain

Start by waiting for the grill to cool completely after your last cook. Putting a cover on a warm grill traps heat and moisture. Once cool, brush off any loose debris. Then drape the cover over the grill starting from the back, pull it forward, and tighten the closure system.

Check that the cover drapes to within a few inches of the ground or grill base. A cover that floats above the ground can let wind underneath and balloon up, which is how covers get torn loose in storms.
