The Onlyfire 18"x12.5" Stainless Steel Griddle Insert offers over 200 square inches of cooking space with a 2.7-inch height. You might search for onlyfire 18 12 5 universal stainless steel alternatives if you need a larger surface area or a different fit for your specific grill model. This original unit provides a non-stick surface and a grease trough for easier cleanup, which appeals to many users. However, its dimensions may not suit every grill, or you might prefer a heavier gauge material for better heat retention.
The alternatives listed here were chosen because their specs overlap with the original product in key areas like material and form factor. You will find options ranging from compact 17-inch plates to massive 36-inch tops. Some models feature nonstick coatings for quick maintenance, while others prioritize durable stainless steel construction. This list covers various sizes and brands to help you find the right match for your cooking habits and available space.
How the Alternatives Compare
Uniflasy 25" x 16" Stainless Steel Nonstick Griddle
The Uniflasy griddle expands your cooking capacity significantly. At 25 inches by 16 inches, it offers much more surface area than the 18-inch Onlyfire model. You get a nonstick coating, which simplifies cleanup compared to bare stainless steel. However, this size increase comes with weight. At 19 pounds, it is more than double the weight of the Onlyfire option. You need a wider grill to accommodate these dimensions. Choose this if you prioritize cooking volume and easy release over portability and a lighter footprint.
Stanbroil 36-Inch Stainless Steel Griddle Top
The Stanbroil 36-inch top is built for specific compatibility. It is designed for 36-inch Blackstone frames, not universal gas grills. You gain 742 square inches of stainless steel space, which dwarfs the 200-square-inch Onlyfire surface. The height is 3 inches, providing deeper sides for flipping. This is not a drop-in replacement for standard grills. You should pick this only if you own a compatible Blackstone stand and need professional-grade capacity. It trades universal fit for massive cooking real estate.
Napoleon 20" x 16" Stainless Steel Griddle Insert
The Napoleon griddle is a precision fit for specific models. It is made for Freestyle and Rogue 425 grills, unlike the universal Onlyfire insert. The cooking dimensions are 18.2 inches by 22.7 inches, offering a different shape than the Onlyfire rectangle. It weighs 21.2 pounds, making it substantially heavier. You get a dedicated stainless steel surface that integrates seamlessly with your existing Napoleon grill. Avoid this if you have a generic gas grill. It is the right choice for brand-specific owners seeking durability and exact fit.
Skyflame 17x13 Stainless Steel Griddle Plate
The Skyflame griddle is a lighter, more compact alternative. It measures 17 inches by 12.8 inches, slightly smaller than the Onlyfire 18x12.5 model. The height is only 2.2 inches, which is lower than the Onlyfire’s 2.7-inch sides. At 6.44 pounds, it is the lightest option here, making it easier to handle. You trade some cooking surface and side height for reduced weight. This is a practical pick for users who want a durable stainless steel plate but need something lighter and easier to store.
Direct 18-Inch Stainless Steel Griddle Top
The Direct griddle is a close universal rival. Its dimensions are nearly identical to the Onlyfire model at 18.1 inches by 12.5 inches. The height is 2.8 inches, which is slightly taller than the Onlyfire’s 2.75-inch sides. It weighs 9.75 pounds, just over a pound heavier. You get a sturdy stainless steel surface suitable for breakfast cooking. The main difference is the marginal weight increase and slightly higher sidewalls. This is a solid alternative if you want a universal fit with comparable dimensions and a bit more side height.
Stanbroil 28-Inch Stainless Steel Griddle Top
The Stanbroil 28-inch top targets Camp Chef grill owners. It is not a universal insert like the Onlyfire model. The size is 28 inches by 17 inches, providing ample space for four-burner grills. You get a large stainless steel surface that is easy to clean. The trade-off is specific compatibility. You cannot use this on a standard gas grill. Choose this if you own a compatible Camp Chef unit and need more cooking area than the 18-inch Onlyfire provides. It prioritizes capacity and brand-specific fit.
