The best Costco grills of 2021

Food & DrinkTrending

Written by:

Wholesale retailer Costco is known for its low prices on big items, which is, perhaps, why it’s a popular destination if you’re in the market for a new grill. While the warehouse chain’s online inventory is not as robust as some home improvement chains, like Lowe’s and Home Depot, there are some good grills in their lineup. Here are the best Costco grills.

The best Costco grills

The best Costco grills are made from high-grade materials and have high customer ratings. They also offer competitive warranties. 

Keep in mind, prices on these grills are subject to change. The cited ratings and number of reviews were accurate at the time of publication. Shoppers should read each grill’s warranty in full to understand what is covered (and what isn’t).

Serious backyard chefs might want to consider this highly rated propane gas grill, which touts all the features you expect from a Weber grill and then some.

It offers 513 square inches (or 20 burgers worth) of primary cooking space.

The grill comes with a number of bells and whistles, including four meat probes, a grill cover, backlit knobs for nighttime grilling and a smart thermometer that pairs with Weber’s iGrill app to send you notices when your food has reached the recommended temperature. 

Reviewers were generally pleased with all of the grill’s features and capabilities, though some reported delivery issues and recommended purchasing in-stores to avoid any shipping-and-handling markups (see below for more details.) Weber offers a 10-year warranty on all parts. It excludes normal wear and tear and stipulates the grill is used in accordance with your owner’s manual, among other things.

The big selling point for the main portable grill in Costco’s lineup is its dual 304-grade stainless steel burners offering 13,500 BTUs (or 6,750 BTUs per burner) across 262 square inches of primary cooking space. It also features cast-iron cooking grates, a built-in thermometer, push-and-turn ignition, and cast aluminum lid and firebox. The grill runs off of a 20-pound propane tank, which is not included. (You can typically purchase one for $15 to $40.)

How to buy a grill at Costco

In order to buy a Costco grill, you’ll need a Costco membership. A standard or Gold Star membership costs $60 a year. An executive membership, which includes 2% rewards on qualified purchases, additional savings on Costco services and benefits on certain Costco travel products, cost $120 a year. There’s also a business membership available for $60 a year, plus an additional $60 for each affiliate cardholder.

Costco technically offers free delivery options on many of its grills. However, its website notes that you may be able to find a lower priced grill in-store — a caveat that some purchasers also called out in their reviews. (For more ways to save on your purchase, check out our article on the best time to buy a grill.) 

Keep in mind, too, some grills won’t arrive until approximately two-to-three weeks from the time of your order. Costco customers can opt to pay an extra $50 for grill assembly. The grills can be returned directly to any of its 700 warehouses.
