📦 Design & Build
This range is as much a statement piece as it is a cooking appliance. The white enamel doors have a high-gloss, mirror-like finish that’s both heat-resistant and long-lasting. Stainless steel trim and a polished finish add to the professional aesthetic. The control knobs have a solid feel, and the LED-lit oven controls give it a modern touch. Adjustable legs make it easier to align with your counters, even in older kitchens.
⚙️ Performance
Here’s what you get on the cooktop:

Rear left: 12,000 BTU
Rear middle: 12,000 BTU

Griddle burner: 15,000 BTU
The dual ovens give you flexibility — use the larger 4.6 cu. ft. oven for roasts, turkeys, or batch baking, and the 2.2 cu. ft. oven for side dishes, bread, or desserts. The convection fan ensures even heat distribution, making it perfect for professional-level results at home.
👌 Ease of Use
The 360° energy regulator allows for precise temperature control, whether you’re searing on high or simmering low. The built-in griddle is a breakfast game-changer — think pancakes, eggs, or smash burgers without extra pans. The LPG conversion kit is included, so you can easily switch fuel types if needed.
💡 Energy Efficiency
Gas ranges are already efficient for high-heat cooking, and having two ovens means you can use just the smaller one for quick meals, saving energy. The convection feature also reduces cooking time for many recipes.
💰 Value for Money
At nearly $4,000, the KOSTCH KOS-48RG03M is an investment piece. But for the serious home chef or entertainer, it’s hard to beat the combination of power, space, and versatility in this size category.

After testing this range, I found myself using the griddle almost daily — from grilled sandwiches to fajitas, it made meal prep faster.
