Bull BBQ Grill Covers, Drip Liners and Griddle Plate: The Fit Guide

The right Bull BBQ grill cover depends on three things: the grill size (24, 30, 38 or 46 inch), whether it is a built-in head or a freestanding cart, and whether the top is a grill or a griddle. Covers run $99 to $179, drip liners $18.99 to $57.99 a pack, and the griddle plate is $319. Get those three answers and the SKU picks itself.

Which Bull BBQ cover fits my grill?

Read the row for your grill. Built-in owners need a head cover. Freestanding owners need a cart cover. Griddle owners need the griddle-specific cover, because it is cut for a different hood. Every price and SKU below comes straight from the live product pages as of November 2026.

We built this matrix because the listing titles are long and the covers look nearly identical in a thumbnail. In my experience the most common wrong order is a 30-inch cover bought for the right size and the wrong grill type. A 30-inch Angus, a 30-inch Bison charcoal and a 30-inch griddle all take a 30-inch cover, and those are three different SKUs.

Two of the rows deserve a flag. The Diablo gap is real and I cover it below. The 24-inch liner is the other one: its web address and listing title say “25-inch 3-burner,” but the product description says it fits Bull’s 24-inch grills. The Steer Premium is 24 inches wide. If you are searching for a 25-inch Bull grill, that is the Steer.

Why does Bull sell separate covers for built-in and freestanding?

A built-in grill is only a head. It sits in an island and the cabinet below is stone, stucco or steel, so the cover only has to wrap the hood. A freestanding grill is a head plus a cart, so the cart cover wraps the whole thing. That is why cart covers cost $60 to $70 more than head covers.

Look at the price gap across sizes. The 24-inch built-in cover is $99 and the freestanding is $159, a $60 spread. At 30 inches it is $99 to $169, a $70 spread. At 38 inches it is $109 to $179, also $70. The extra money buys more fabric, nothing fancier.

Here is the part that trips people up. The material changes between the two types and across sizes. Per the listings, the 30-inch head cover (45005), the Bison head cover (72018) and the 38-inch head cover (56006) are 300D polyester. The 24-inch head cover (72016), the Diablo head cover (72017) and every freestanding cart cover for Steer, 30-inch and Brahma are heavy-duty vinyl. The 30-inch griddle cart cover (72020) is 300D polyester, and the griddle head cover (72019) is described as all-weather with an elastic hem.

How do the cover types compare at a glance?

Is a 300D polyester cover good enough?

For a grill under a roof or a pergola, yes. For a grill sitting in open sun, wind and coastal air, 300D is the thin end of the range. Bull publishes 300D on several of its head covers, and our own cover guide calls anything under 600D a light-duty fabric. Both things are true at once, and the honest answer is that the cover buys you protection from dust, pollen and rain, not a ten-year shield.

Here is where I disagree with the usual advice, and where this guide gives you something a generic roundup will not. Most cover guides tell you to buy the heaviest denier you can find. That is correct for the fabric. It is incomplete for the fit. A tailored $99 head cover that actually closes under the hood lip and ties down will outlast a heavier universal cover that flaps and chafes at the corners. Fit is what keeps wind from working the seams. Our grill cover buying guide covers denier, seam construction and vents in detail, and it is the right read if your Bull lives uncovered through a northern winter.

What does that mean in practice? If your Bull sits on a covered patio, the $99 head cover is a sensible dust sleeve. If it sits in the open, budget for replacing the cover every few seasons and treat it as a consumable, the way you treat the drip liners.

What if I own a Diablo?

The built-in Diablo head has a cover: SKU 72017 at $119. The freestanding Diablo has no Bull-made cart cover in the catalog, and there is no Diablo drip liner either. Do not assume the 38-inch Brahma products stretch to cover a 46-inch grill. They do not.

We learned to flag this gap the hard way. A 46-inch grill is eight inches wider than the Brahma, and a cover cut for 38 inches will not reach the end caps. The Diablo built-in cover’s listing has its own wrinkle: the product title says 46-inch, but the web address says 42-inch. That is a naming leftover. The title, the description (it names the Diablo grill head) and the product match each other. Trust the 46-inch title.

For a freestanding Diablo, measure width, depth and total height from the floor to the top of the hood, then call us before you buy anything. We can talk you through what makes a decent aftermarket fit, and whether a built-in head cover is wide enough for your cart configuration. Do not buy blind.

Drip liners follow the same pattern. Bull’s liner range stops at the 38-inch Brahma pack, so ask us what we recommend for the Diablo tray rather than trimming a smaller liner to fit.

Which cover fits a Bull griddle, and can I use the grill cover?

Use the griddle cover on a griddle. Bull sells two: SKU 72019 for the 30-inch built-in griddle head and SKU 72020 for the freestanding griddle cart, both $109. The grill covers named for Angus, Lonestar Select and Outlaw are not interchangeable with them, even though every one of these is 30 inches.

The Bull 30-inch 4-burner built-in griddle has a flat cook top and no hood. A hood-shaped cover will hang wrong on it. That is why Bull cut a dedicated cover with an elastic hem for the built-in version, so it does not billow in wind.

What is the Bull slide-in griddle plate, and is $319 worth it?

The Bull slide-in griddle plate (SKU 97020, $319) is a removable 304 stainless steel flat top with a built-in grease trough. It replaces two cooking grates on any Bull grill. For eggs, pancakes, tacos and smash burgers on a grill you already own, it is the cheapest way into flat-top cooking.

Put it next to the alternative. The 30-inch built-in natural gas griddle is $2,769. The plate is $319. That is a gap of $2,450 before you pay for a cutout in the island, a gas line and a cover for the second appliance. If a griddle is a once-a-week cook and you already own an Angus, Outlaw, Lonestar Select or Brahma, the plate is the sane choice.

Where the plate loses: it shares your grill’s burners and grate layout, so you are not getting a dedicated multi-burner griddle with its own zones. If you griddle for a crowd every weekend, the stand-alone unit earns its price. Everyone else should start with the plate.

One practical note from the listing: it slides in and out, so it stores off the grill. Keep it dry and oiled between cooks, because stainless gets spotty if it sits wet. That is general stainless care, not a Bull-specific rule.

How much do Bull drip pan liners really cost?

Per piece, Bull liners cost about $4.00 for the 30-inch (box of 12 at $47.99), about $4.83 for the 38-inch (box of 12 at $57.99), and about $6.33 for the 24-inch (set of 3 at $18.99). The smallest grill has the highest cost per liner because Bull only packs it in threes.

That last column is my arithmetic, not a Bull recommendation. Change the liner as often as your cooking demands. Heavy smash-burger and rib weeks burn through them faster than a quiet winter. The point is the order of magnitude: a year of liners for a 30-inch grill costs about what a single head cover does, and a liner is the cheap part of keeping grease fires off your list of worries.

What are the liners actually made of?

Per the listings, they are lightweight disposable aluminum trays that sit in the grease tray. That is all the listings state, so I will not invent a gauge or a temperature rating. Let the tray cool before you lift it out, and bag the liner with the grease rather than dumping the pan into the yard.

Which liner pack is the better deal?

The 30-inch box of 12 at $4.00 a liner is the best per-piece price of the three, and it covers the three most popular Bull models (Outlaw, Lonestar Select, Angus). The 24-inch set of 3 is the one to watch if you own a Steer and cook often: you will reorder it often, and the per-liner cost stays the highest of the range.

Is the Bull grill jacket a cover?

No. The Bull insulated grill jacket is an installation part for building a grill into a combustible enclosure, such as a wood-framed island. It has a stainless steel exterior and costs $649 for 30-inch grills (SKU 47017) or $729 for 38-inch grills (SKU 47018). It does not protect a grill from weather.

This is the claim we had to fix elsewhere on our own site. An earlier version of our Bull grill lineup guide pointed to the jacket for coastal installs. The product page says the opposite: it is for combustible framing. If you are building an island out of wood studs, you need the 30-inch jacket or the 38-inch jacket as part of the build. If you are near the coast and want protection from salt air, you need a cover and a rinse routine. Different jobs.

If you are planning the island itself, the jacket decision belongs in the first drawing, not the accessory cart. Tell your builder which grill head you picked before the framing goes up.

What should I buy together for each Bull grill?

For most Bull owners the right starter set is one cover and one liner pack. On a 30-inch built-in that is $146.99. On a freestanding Angus it is $216.99. Add the $319 griddle plate if flat-top cooking is on the list.

Totals are listed prices as of November 2026 and exclude tax and shipping. Prices change, so confirm on the product page before you order.

How do I confirm the fit before I order?

Check four things: the model name on your grill, built-in or freestanding, grill or griddle, and the size in inches. Match those to the row in the fit matrix. If any of the four is a guess, stop and confirm before ordering.

1. Model. Steer Premium, Outlaw, Lonestar Select, Angus, Bison, Brahma, Diablo or griddle. Read the model off the grill, not off the order confirmation.
2. Built-in or freestanding. Is there a cart under it? A cart means a cart cover. A masonry or steel island means a head cover.
3. Size. 24, 30, 38 or 46 inches. The title on every Bull accessory lists this.
4. Fuel and tray. Liners are sized for gas grill trays. If yours is charcoal, skip the liners.

If you are still choosing the grill itself, start with the complete Bull BBQ buyer’s guide or the head-to-head in Weber vs Bull vs Coyote. Our Angus review and Brahma review go deeper on the two models most buyers land on. The whole catalog, grills and accessories, sits on the Bull BBQ brand page.

What do most Bull owners get wrong with covers and liners?

Three mistakes cause most wrong orders: ordering by size alone, buying a head cover for a freestanding grill, and treating the jacket as weather protection.

Ordering by size alone. Thirty inches covers three grills, a charcoal Bison and a griddle. The title names the grill for a reason. Read it to the end.

Head cover on a cart. A head cover is cut for the hood only. If there is a cart under the grill, you want the $159 to $179 cart cover sized for it.

Jacket as a cover. Covered above. Different part, different job, and $550 more expensive than the cover it gets mistaken for.

One more, smaller than the others: skipping liners entirely. Grease that bakes onto the tray is a chore. A liner turns that chore into a thirty-second swap. At $4.00 each on the 30-inch box, I would rather pay for the liner than scrape the pan.
