Our top pick: KOSTCH 36-Inch 6-Burner Gas Range.
How these models differ from the KOSTCH
AAOBOSI 36-Inch 6-Burner Gas Range
The AAOBOSI model shares the 36-inch width and six-burner layout, but it weighs significantly less at 140 pounds compared to the KOSTCH’s 240 pounds. It also includes a self-cleaning oven feature, which the KOSTCH does not list. Both units offer convection cooking and manual controls. The AAOBOSI is a lighter, easier-to-move option with added cleaning convenience. If you prefer a simpler cleanup process and do not need the heavy-duty build of the KOSTCH, this model provides similar burner power with less physical bulk. It lacks the explicit propane conversion kit details found in the KOSTCH specs.
COSMO 36-Inch Vista 6-Burner Gas Range
The COSMO Vista model is slightly narrower at 35.8 inches and taller at 38.4 inches, differing from the KOSTCH’s 36.6-inch height. It weighs 206 pounds, which is lighter than the KOSTCH. Both are 36-inch class ranges with six burners and convection ovens. The COSMO focuses on even heat distribution rather than maximum raw BTU output. If your kitchen has height restrictions or you prefer a slightly different footprint, this model fits well. It offers standard convection performance without the high-output burner emphasis of the KOSTCH. It is a solid choice for standard 36-inch spaces needing reliable convection cooking.
COSMO 36-Inch 6-Burner Convection Gas Range
The COSMO Haven model matches the KOSTCH in width and burner count but is shorter at 35.6 inches. It weighs 235 pounds, close to the KOSTCH’s 240 pounds. This model features dual 18,000 BTU burners, offering more high-heat options than the KOSTCH’s single 18,000 BTU burner. Both use convection and manual controls. The COSMO provides robust construction and straightforward operation. If you need multiple high-power burners for heavy-duty cooking, this model gives you more high-heat capacity. It lacks the included propane conversion kit mentioned for the KOSTCH but delivers comparable convection performance and durable build quality.
COSMO 36-Inch Stellar 6-Burner Gas Range
The COSMO Stellar model is a 36-inch range with six burners and air fry functionality, which the KOSTCH does not list. It shares the stainless steel color and gas fuel type. Both are freestanding units. The Stellar model adds air fry as a cooking feature, providing versatility beyond standard convection baking. If you want dedicated air frying capabilities alongside high BTU output, this model is a strong alternative. It focuses on air fry convenience and strong burner performance. The KOSTCH offers a larger oven capacity and propane conversion, but the Stellar model adds air fry utility for those who prioritize multi-function cooking modes.
KOSTCH 36-Inch Gas Range with Range Hood
This KOSTCH model includes a matching range hood, which the original standalone KOSTCH range does not. It shares the same 36-inch width, six burners, and 36.6-inch height. The weight is not listed, but the dimensions and model number suggest similar construction. If you need ventilation included in your purchase, this bundle saves you from buying a separate hood. It offers the same high-output burners and convection oven. The main difference is the addition of the hood unit. For cooks who want a complete ventilation and cooking setup, this model provides both. It lacks the standalone flexibility of the original but includes essential exhaust components.
Vulcan 36-Inch 6-Burner Natural Gas Range
The Vulcan model is a 36-inch range with six burners but has a much greater height at 58 inches. It weighs significantly more, though the exact weight is not listed. Both are gas ranges with six burners. The Vulcan offers a standard 36-inch footprint but differs in vertical space requirements. If your kitchen has high ceilings or you need a taller unit for specific installation reasons, this model fits. It provides robust burner count without the convection or propane conversion details of the KOSTCH. It is a straightforward six-burner option for those prioritizing width and burner count over advanced oven features or compact height.
