COSMO COS-GRT366 36 in Gas Cooktop - 6 Italian Burners

In this review of the COSMO COS-GRT366 gas cooktop, the bottom line is simple: this 36 in, six-burner range-top is for home cooks who need high heat and flexible burner options without upgrading to a full range. The review finds the standout feature is the mix of two 18,000 BTU dual-ring burners with mid and low-power burners, which delivers both searing power and gentle simmering in one compact slide-in unit. Cleanability and durable materials also make it a practical choice for busy kitchens seeking a performance cooktop.

Key Features

• Six sealed Italian burners: A combination of two 18,000 BTU, two 12,000 BTU, and two 8,000 BTU burners provides a wide power range for everything from rapid boiling to low simmering.
• Dual ring 18,000 BTU burners: The dual ring design gives responsive high heat for searing and fast boiling while allowing finer control when needed.
• Black porcelain cooktop surface: The smooth porcelain finish makes daily cleanup straightforward and resists staining during routine use.
• Dishwasher-safe cast iron grates: Heavy-duty flat cast-iron grates let pots slide between burners and can be removed for cleaning, simplifying maintenance.
• Metal front knob controls: 304-grade stainless steel knobs offer a sturdy feel and clear flame adjustment at the front of the unit for convenient control.
• Advanced safety features: Electronic ignition and flame failure technology add safety and reliable starting for routine cooking.

Who It's For

The COS-GRT366 suits home cooks who regularly use multiple burners at once and want powerful, chef-style performance in a 36 in cooktop footprint. It works well in modern kitchens that benefit from a stainless steel, slide-in presentation and for anyone who values durable cast-iron grates and high-BTU burners for searing.

Those who should look elsewhere include buyers needing induction cooking, an integrated oven, or significantly lower-profile residential cooktops; similarly, if you require countertop-level controls or a cooktop narrower than 36 in, this model may not match your installation needs.

Pros & Cons

Pros

• Powerful dual-ring 18,000 BTU burners that handle high-heat tasks like searing and rapid boiling.
• Versatile six-burner layout with a range of outputs for multitasking while cooking.
• Durable 304-grade stainless steel metal knobs and removable cast-iron grates for long-term use and easier cleaning.
• Built-in safety with electronic ignition and flame failure technology for reliable operation.

Cons

• As a gas slide-in cooktop, it requires a compatible installation and 110V electrical hookup; not suitable for those seeking induction or electric-only options.
• The cooktop surface is black porcelain which, while easy to wipe, can still show wear or require careful cleaning to maintain a pristine look.
