Are Kirkland Grills Good? | What Buyers Should Know

Kirkland grills often give you a lot of stainless steel and cooking room for the price, but long-run parts access varies by model.

Kirkland Signature grills hit a familiar Costco formula: big cook boxes, lots of burners, and pricing that can undercut many same-size name-brand grills. That can feel like a no-brainer. It can also leave you wondering what happens after a couple of summers in the heat and rain.

This article answers that in plain terms: how they’re built, how they cook, and what ownership looks like once the return window is behind you.

Are Kirkland Grills Good? For Real-World Backyard Cooking

If you want a large gas grill with wide grates and plenty of burner space, Kirkland models can be a strong buy. In many cases you get features like a side burner, a rear burner, and extra storage without paying a “badge tax.”

The catch is consistency. Costco rotates inventory, and Kirkland-branded grills don’t always stay on sale year-round. That makes model numbers matter more than the logo on the lid.

What A Kirkland Grill Is And Who Makes It

Kirkland Signature is Costco’s house label, not a manufacturer. A Kirkland grill is produced by an outside grill company and sold under the Kirkland name. Many Kirkland gas grills share model-number patterns seen on Nexgrill-built units (often 720-xxxx), which is useful when you’re hunting manuals and replacement parts.

Practical takeaway: save the model number the day you buy. A quick photo of the data plate or product listing can save you hours later.

Build Quality Checks You Can Do In Two Minutes

Warehouse grills look similar at a distance. Up close, you can spot the stuff that decides whether a grill lasts one season or many.

Start with the “hot zone” parts

• Burner tubes: They should feel solid and sit straight. Deep pitting, cracked welds, or heavy rust is a red flag on a used unit.
• Heat plates: Look for wide coverage over each burner. Gaps and warping often lead to flare-ups and hot spots.
• Firebox floor: Peek under the grates. If the bottom is flaky or thin, the grill may be near the end even if the outside shines.

Then check the structure

Open the doors. Push gently on the side shelves. If the cart twists or the doors bind, the frame may be light. A steadier cabinet keeps panels aligned and reduces rattles over time.

How They Cook: Heat, Control, And Evenness

Big BTU numbers are easy to print on a tag. The more useful question is whether the grill gets hot across the whole grate and holds a steady low setting when you want it.

Preheat and searing

Plan on 10–15 minutes of lid-closed preheat for most gas grills. Once hot, many Kirkland models sear well if the grates have enough mass. If the grates are lighter, you can still get good browning by giving the grill more preheat time and avoiding overcrowding.

Low-and-slow on a gas grill

For ribs or chicken, you want smooth knobs that let you run one or two burners low while the rest stay off. A lid that closes evenly helps a lot. If you can, test the floor model lid for wobble and check that the thermometer sits tight.

A simple heat-map test

Once you own the grill, map hot spots with bread. Lay slices across the grates on medium heat for a few minutes, then check browning. That quick test teaches you where to park thick chicken pieces and where to put quick-cooking vegetables.

Warranty And Returns: What To Read Before You Buy

Costco’s satisfaction guarantee is a reason many people try a Kirkland grill. Still, you should know two things: the store policy for your category, and the warranty info tied to the exact model you’re buying.

Costco publishes the broad policy and the main categories with special limits. Costco’s return policy details are worth a quick read so you know what to expect if something arrives damaged or fails early.

Also check the “Manuals & Guides” and warranty section on the product page, since that’s where you’ll usually find the model number and the manufacturer warranty info in one place. The Kirkland Signature 6-burner grill listing shows where Costco posts manuals and specs for a current model.

Buying New Versus Used

New gets you clean internals, easy returns, and a clear paper trail for warranty claims. Used can save a lot of money, yet it can also turn into a parts hunt if the grill is missing pieces or the data plate is gone.

New-buy tips

• Pick the model that fits your patio, then buy when it’s in stock instead of waiting for a “maybe later” restock.
• Confirm fuel type (propane vs natural gas). Conversions are not always approved and can be unsafe if done wrong.
• Download the manual the same day and save it in cloud storage.

Used-buy tips

• Ask for a photo of the model plate before you drive over.
• Lift the grates and heat plates to inspect the firebox floor and grease channels.
• Expect wear parts: burners, heat plates, and igniters may need replacement.

What To Check Before You Buy Or Pick One Up Used

Use this list in the aisle or in a driveway. It keeps you from paying for a grill that’s already on its last legs.

Check Point	What To Look For	Why It Matters
Model number	Clear ID on listing or data plate	Makes manuals and parts searches doable
Burner tubes	Straight, clean ports, no deep rust pits	Drives heat output and evenness
Heat plates	Wide coverage, not warped through	Reduces flare-ups and spreads heat
Firebox floor	No holes, no flaky rot	Rust here can end a grill early
Lid fit	Closes evenly, minimal rocking	Helps temp control for indirect cooks
Ignition	Each burner lights without repeat clicks	Flags electrode, wire, or valve issues
Regulator and hose	No cracks, no kinks, no fuel smell	Gas safety check before cooking
Cart rigidity	Doors align, shelves don’t sag	Less rattle, longer panel life

Common Pros And Cons In Daily Use

Pros people tend to notice

• Cooking space: You can run big batches for family meals or parties.
• Features for the money: Side burners, rear burners, and storage show up often.
• Easy weeknight cooking: Gas is fast to light and simple to control.

Cons that can show up later

• Model turnover: The exact unit may be gone next season.
• Mixed internal metals: Some inner parts can rust before the outer shell does.
• Parts shopping takes effort: It’s smoother if you saved the model number.

Where Buyers Get Surprised

Most complaints about big stainless warehouse grills come from a few repeat patterns. Knowing them up front helps you choose the right model and treat it right once it’s on the patio.

Rust shows up inside first

Stainless on the outside doesn’t mean every inner part is stainless. Heat plates, burner brackets, and the firebox floor take the harshest mix of heat, grease, and moisture. If you see surface rust on a store display, don’t panic. If you see flaking metal under the grates on a used grill, walk away.

More burners can mean more fiddling

Six-burner carts look fun, yet they also create more seams and more heat zones. That’s fine if you like zoning food across hot and cooler areas. If you want simple, a smaller burner count with thicker parts can be the calmer choice.

Parts are easy only when you saved the model

Many Kirkland owners lose the manual, then search “Kirkland grill burner” and hit a wall. Save the model number and the part diagram early. Then parts shopping becomes a normal task, not a guessing game.

Care Habits That Keep Them Cooking

Most grill deaths are grease and rust, not “mystery defects.” A few habits go a long way.

After each cook

• Run burners on high for 3–5 minutes with the lid closed, then brush the grates.
• Empty the grease tray before it overflows.
• Cover the grill only after it’s cool and dry.

Every month in grilling season

• Pull grates and heat plates and scrape the firebox floor and grease channels.
• Clear burner ports with a soft brush if you see debris.
• Check fasteners on handles and doors and snug them if they loosen.

Small Tweaks That Pay Off

You don’t need a pile of add-ons. A couple of low-cost changes can make a big grill easier to live with.

Use a simple grate routine

After you brush, wipe the grates with a lightly oiled paper towel held with tongs. It reduces sticking on fish and chicken and slows rust on cast grates.

Keep a spare igniter battery and a long lighter

Many grills use batteries for ignition or knob lights. A spare battery and a long lighter keep dinner on track if the igniter decides to quit mid-season.

Add an extra thermometer only if you cook by numbers

Lid thermometers often read hotter than grate level. If you do lots of indirect cooks, a clip-on probe at grate height gives you a more honest reading and helps you repeat results.

Which Kirkland Grill Fits Your Cooking Style

Kirkland grills come in a few common shapes: mid-size carts, large carts, and extra-large island builds. Use your space and your habits to choose.

Cook Type	Traits To Favor	Trade-Off To Accept
Weeknight griller	Simple controls, easy cleanup	Less room for big parties
Entertainer	More burners, wide warming rack	More parts to maintain
Steak fan	Heavier grates, strong preheat	Higher gas use at max heat
Indirect-cook cook	Tight lid fit, smooth low settings	Needs practice with burner zones
Small patio owner	Narrow cart, fold-down shelves	Less prep space
Used-market hunter	Clean firebox, clear model plate	May need new wear parts

Decision Checklist Before Checkout

Run this last pass and you’ll dodge most regrets.

• Fuel type matches your setup (propane vs natural gas).
• Model number saved and manual downloaded.
• Grates and heat plates feel solid, not flimsy.
• Grease tray pulls out easily and the drain path is clear.
• Lid closes evenly and the cart feels steady.
• If buying used, price replacement burners and heat plates before you pay.

Verdict On Kirkland Grills

For many shoppers, yes. The value is strongest when you want lots of cooking room and Costco-style pricing. Treat the grill like a real appliance: keep the model number, clean it on a schedule, and replace wear parts when they age out. If that sounds fine, a Kirkland grill can be a satisfying long-term backyard workhorse.
