Who it fits
Good fit for
This range suits cooks who need maximum burner power and large oven space. It fits well in professional-style kitchens where a 36-inch footprint is standard. The high BTU output is ideal for searing steaks or boiling large pots quickly. The included LP conversion kit makes it versatile for homes with different gas lines. If you value traditional mechanical controls and a robust build over digital interfaces, this model aligns with your needs.
Who should skip it
Skip this model if you prioritize smart home integration or digital displays. The controls are mechanical 360° regulators, not electronic touchpads. There is no mention of Wi-Fi, app connectivity, or remote monitoring. The design is traditional rather than minimalist. If you prefer a sleek, handle-less look or automated cooking cycles, this mechanical interface may feel outdated. It is also heavy, requiring sturdy cabinetry support.
Verdict: The KOSTCH 36-inch range delivers high BTU output and large capacity for traditional cooking. It is a solid choice for those who value power and durability over digital features.
Key specs explained
Maximum BTU: 18,000 BTU
This rating indicates the highest heat output available on the front right and left burners. High BTU allows for rapid water boiling and quick searing of steaks. You benefit from faster cooking times and better control over high-heat techniques. When shopping, compare this to standard ranges that often top out at 9,000 to 12,000 BTU for their strongest burners.
Number of Burners: 6
The cooktop features six individual gas burners, providing ample workspace for multiple pots and pans simultaneously. This layout suits families or hosts who prepare large meals frequently. You can keep sides warm while main dishes cook. Compare this to smaller four-burner models, which may force you to cook in batches during busy dinner services.
Oven Capacity: 6.0 cu. ft.
This interior volume offers significant space for large roasts, multiple sheet pans, or a whole turkey. You gain flexibility in meal planning and holiday cooking. The spacious cavity accommodates standard large bakeware without crowding. When comparing ovens, note that many standard 30-inch ranges offer only 4 to 5 cubic feet of capacity.
Gas Type: Natural gas or liquid propane
The range includes a conversion kit, allowing you to switch between natural gas and liquid propane fuel sources. This versatility is useful if you move to a home with different infrastructure or if your local supply changes. You follow the included instructions to make the switch safely. Always verify your home’s gas type before purchase.

The KOSTCH 36-inch range presents a professional aesthetic with a stainless steel finish. According to the listing, the oven door features a high-quality enamel coating. This surface is described as smooth, bright, and mirror-like. It is heat-resistant and distinct from powder-coated alternatives. This finish choice aims for long-lasting durability and a premium look in your kitchen. The unit weighs 240 pounds, providing substantial stability. Its dimensions are 36 inches wide, 27.5 inches deep, and approximately 36.6 inches high. Four legs with adjustable height allow for leveling on uneven floors.

The control layout centers on a 360° energy regulator. This mechanism lets you dial in precise heat levels for each burner. The metal oven light and fan buttons include LED indicators for clear visibility. Inside, the oven offers a 6.0 cubic foot capacity. A convection fan ensures even air circulation during baking and roasting. The six single gas burners are arranged in a pro-style layout. The front right and left burners deliver 18,000 BTU. The front and rear middle burners provide 12,000 BTU. The rear right and left burners offer 9,000 BTU. This configuration gives you flexibility for different cookware sizes. You can manage high-heat searing and gentle simmering simultaneously. The range operates on natural gas or liquid propane. An LP conversion kit is included for switching fuel types.
Setup and Everyday Use
This KOSTCH 36-inch gas range is a freestanding unit designed for straightforward installation in standard kitchen layouts. The dimensions are 36 inches wide, 27.5 inches deep, and approximately 36.6 inches high. It weighs 240 pounds, so you should plan for careful handling during placement. The range stands on four legs that allow for height adjustment. This feature helps you level the unit on uneven floors, ensuring stable operation.
Fuel flexibility is a key aspect of setup. The unit comes with a liquid propane conversion kit. This allows you to switch from natural gas to liquefied petroleum gas by following the included instructions. You do not need to purchase separate adapters. The control type uses a 360-degree energy regulator. This dial mechanism gives you precise heat control for each of the six burners. You can adjust the flame intensity smoothly without clicking or stepping through discrete settings.
Daily use involves managing six single gas burners. The output varies by position. The front right and left burners deliver 18,000 BTU. The middle burners provide 12,000 BTU.

Before you buy this range
You should verify your kitchen’s gas line compatibility before ordering. This unit comes with a liquefied propane conversion kit, but you must ensure your home’s supply matches the initial natural gas setup or follow the instructions to convert it. The 36-inch width requires a dedicated space, so measure your cabinetry clearance carefully. The freestanding design allows for easy placement, yet the 240-pound weight means you may need assistance for safe installation. Regularly clean the stainless steel finish and the enamel-coated oven door to maintain the mirror-like surface. Check that your electrical outlets can support the control panel and LED indicators. This model fits well in larger kitchens where high output and convection cooking are priorities. Compare its 6.0 cubic foot capacity against other options in this guide to ensure it meets your storage needs for large roasts or multiple pans. Ensure your ventilation system can handle the heat from the 18,000 BTU burners.
Check before you buy
- Confirm your gas line matches natural gas or propane.
- Measure your kitchen space for the 36-inch width.
- Check electrical outlet availability for the control panel.
- Ensure ventilation handles high BTU output.
- Plan for moving the 240-pound unit.
