Outdoor Grill Cover Buying Mistakes to Avoid in 2026
The Unicook 55-inch Grill Cover is the best pick here for most three- and four-burner owners because its stated fit, ventilation and straps solve the mistakes that shorten a cover's useful life. The biggest outdoor grill cover buying mistake is treating a cover as universal: a cover only protects well when its width, depth and height suit the closed grill.
Outdoor grill cover mistakes to avoid before ordering
Start with the grill rather than its brand name. Measure the widest point, the front-to-back depth including handles, and the height with the lid shut. The 55-inch Unicook is listed at 55 W x 23 D x 42 H inches and is intended for many grills up to 53 inches wide. The 52-inch Unicook is a closer 52 W x 25.8 D x 42.8 H fit for Weber Spirit 200 and 300 series grills, while the iCOVER is the roomier option at 58 x 24 x 45 inches for grills up to 58 inches wide.
Do not select by width alone. Extra length can gather on the ground and hold water; a cover that is too shallow can leave the back or side shelves exposed. Compatibility wording is useful only after the dimensions agree. In particular, the 52-inch Unicook explicitly does not fit Spirit II 300 models or older Spirit E-310 grills with the gas valve on the right-side table. That kind of exception is exactly why a model name is not a substitute for checking the product page and your own grill.
Another common mistake is assuming waterproof fabric needs no airflow. Rain resistance matters, but a sealed damp space can leave condensation against a cooled grill. The 55-inch Unicook has concealed ventilation holes on both sides to circulate air and let moisture escape. It also uses a waterproof vinyl underlining beneath fade-resistant fabric. The specialized 52-inch Unicook uses fade-resistant polyester with a waterproof vinyl coating, whereas the iCOVER uses Oxford fabric with a waterproof PVC coating and high-density double-line stitching. These are useful construction details, not a reason to skip drying the grill before covering it.

The three covers, and the fit errors they prevent
Unicook 55-inch Grill Cover
The Unicook 55-inch is the balanced choice for a conventional three- or four-burner gas grill that measures no more than 53 inches wide. Its 55 W x 23 D x 42 H inch shape gives a small allowance without jumping immediately to an oversized cover. More importantly, it combines 1.5-inch fastening straps with concealed vents on both sides, so it addresses two practical failure points: wind lift and moisture retained under the fabric. The stated heavy-duty, fade-resistant fabric has a waterproof vinyl underlining, and the two top handles make removal less awkward. Choose it when you want a broadly compatible cover with ventilation rather than a brand-specific cut. Its limitation is fit precision: grills with deep rear hardware, very broad shelves, or a width above 53 inches need a different measurement match.
Pros
- Concealed vents on both sides help moisture escape instead of enclosing a damp grill.
- 1.5-inch fastening straps provide a defined wind-retention system.
- 55 W x 23 D x 42 H dimensions suit many three- and four-burner grills up to 53 inches wide.
Cons
- The listed fit stops at 53 inches wide, despite the cover's 55-inch overall width.
- It is not the precise shaped option for a Weber Spirit owner who wants a model-specific cut.
Unicook 52-inch Spirit Cover
This Unicook earns the Weber Spirit badge because its 52 W x 25.8 D x 42.8 H inch dimensions match the Weber 7106 cover dimensions and it is specified for Spirit 200 and 300 series grills, including Spirit 210 with the tables up. The extra depth compared with the general-purpose 55-inch model matters when side tables and the lid profile dictate the shape. Heavy-duty fade-resistant polyester and its waterproof vinyl coating are designed to resist UV exposure, rain, tearing and cold cracking; fastening straps keep the hem from slipping in wind. Handles also serve for lifting and hanging the cover after it dries. It is the sensible choice for the stated compatible Spirit models, not a generic recommendation for every Weber. It expressly excludes Spirit II 300 and older right-valve Spirit E-310 configurations, so confirm the generation before ordering.
Pros
- Its 52 W x 25.8 D x 42.8 H dimensions are matched to the Weber 7106 cover size.
- The listing specifically covers Spirit 200 and 300 series grills, including Spirit 210 with tables up.
- Fade-resistant polyester with waterproof vinyl coating is described as resistant to UV, rain, tears and cold cracking.
Cons
- It does not fit Spirit II 300 models or older Spirit E-310 grills with the right-side gas valve.
- Its 50-inch maximum compatible grill width is less forgiving for broad non-Weber grills.
iCOVER 58-inch Grill Cover
The iCOVER is the better answer when the grill is wider than the Unicook 55-inch's stated 53-inch compatibility limit. Its 58 x 24 x 45 inch dimensions are designed for most three- to five-burner grills up to 58 inches wide, so it gives larger gas grills a more appropriate starting point. The construction is lightweight Oxford fabric with a waterproof PVC coating, plus high-density double-line stitching intended to resist wear at seams. Instead of hook-and-loop straps, this model uses an adjustable drawstring closure to cinch the lower edge against wind. That is useful on a grill whose width suits the cover, provided the cord can be tightened evenly. Choose it for the wider size range and a simple adjustable hem. The tradeoff is that it has no listed ventilation system, so covering a warm or wet grill would be an especially poor choice.
Pros
- 58 x 24 x 45 inch sizing is intended for grills up to 58 inches wide.
- Oxford fabric, waterproof PVC coating and double-line stitching target weather exposure and seam wear.
- An adjustable drawstring lets the lower edge be cinched to the grill instead of relying on a fixed hem.
Cons
- No ventilation feature is listed, so it is less suited to trapping residual moisture after rain or cleaning.
- The larger cut can be excessive on a compact two-burner grill and may leave loose fabric to manage.
Care mistakes that defeat a good cover
Never put any of these covers over a hot grill. Apart from the burn risk, heat and trapped moisture can stress coated fabric. Let the appliance cool completely, brush away loose grease and food residue, and dry standing water from the lid before fitting the cover. Tighten the Unicook straps or the iCOVER drawstring after it is positioned, rather than yanking the cover into place by a seam.
Cleaning also deserves restraint. Both Unicook listings direct owners to hose the cover and air-dry it in the sun; the 52-inch version says it is not machine-wash safe. A gentle rinse removes pollen and dirt without treating a coated fabric as laundry. Take the cover off occasionally in a long wet spell to inspect the grill and let both surfaces dry.
FAQ
Should a grill cover touch the ground?
No. A cover should reach low enough to protect the cabinet and wheels without pooling on the patio. Fabric resting in puddles can stay wet and dirty, while excess material is easier for wind to catch. Measure height as well as width, then choose the smallest cover that still accommodates the closed lid and normal shelf position.
Are vents important in a barbecue cover?
They can be useful because outdoor temperature changes can create condensation under a cover. The Unicook 55-inch model lists concealed vents on both sides, while the iCOVER listing does not specify vents. Vents do not make it safe to cover a hot or wet grill, but they can reduce retained moisture after the grill has cooled and dried.
How do I know whether the 52-inch Unicook fits my Weber Spirit?
Compare your grill's measured dimensions and configuration with the listing, not just the word Spirit. This cover is specified for Spirit 200 and 300 series grills and Spirit 210 with tables up. It excludes Spirit II 300 models and older Spirit E-310 models with the gas valve on the right-side table, so those exclusions need checking first.
