Specifications side by side

COSMO Cooktops Ranked by Specs

The COSMO lineup features gas cooktops designed for different kitchen layouts. The primary differences lie in width and burner count. You can choose between a 30-inch model with five burners or a larger 36-inch unit with six burners. Both units are constructed from stainless steel for durability. The 30-inch Haven model fits standard drop-in spaces, while the 36-inch option suits larger openings. Both models prioritize high heat output for daily cooking tasks. The 36-inch unit includes metal controls for precise adjustment. You should select the size that matches your cabinet dimensions. Check the burner count to ensure it meets your cooking volume needs. This comparison helps you pick the right fit for your kitchen.

Where COSMO fits your kitchen

COSMO offers gas cooktops in two main sizes. You can choose a 30-inch drop-in model with five burners. This suits standard kitchen upgrades. The other option is a 36-inch slide-in unit with six burners. This fits larger openings and provides more burner flexibility. Both models feature stainless steel construction and Italian burner components. The lineup covers standard widths for most homes. It does not include 24-inch or 48-inch options. You also will not find induction or electric models in this selection. The brand focuses strictly on gas performance in these two configurations.

Choose Your COSMO Cooktop Specs

1. Match Your Cabinet Width

   Check your existing cutout size before buying. The 30-inch Haven model fits standard 30-inch openings with a width of 30.3 inches. If you have a larger 36-inch opening, consider the 36-inch slide-in unit, which measures 35.9 inches wide. Choosing the correct width ensures the cooktop sits flush with your countertop. Measuring your space accurately prevents installation issues and guarantees a proper fit for your kitchen layout.

2. Select Burner Count

   Decide how many pots you cook with simultaneously. The 30-inch Haven offers five burners, which handles most daily meals efficiently. The larger 36-inch model provides six burners for maximum flexibility. More burners allow you to prepare complex dishes with multiple components at once. If you frequently host dinners or cook elaborate meals, the extra burner space in the larger unit is practical. Match the count to your typical cooking volume.

3. Check Installation Type

   Identify whether you need a drop-in or slide-in unit. The Haven is a drop-in cooktop, designed to sit into a countertop cutout. The 36-inch model is a slide-in unit, which slides under existing cabinetry. Drop-in models are common for standard kitchen upgrades. Slide-in units often provide a seamless look with adjacent appliances. Your choice depends on your current kitchen design and whether you are replacing an existing unit or building new.

4. Consider Weight Capacity

   Ensure your countertop can support the unit. The 30-inch Haven weighs 41 pounds, making it manageable for standard cabinetry. The 36-inch slide-in model weighs 84.9 pounds due to its larger size and additional burners. Heavier units require sturdy support structures. Verify that your cabinet frame and countertop material can handle the weight. This is especially important for the larger model to prevent sagging or damage over time.

5. Verify Material Durability

   Look at the finish and build quality. Both models feature stainless steel construction, which resists corrosion and is easy to clean. Stainless steel is a practical choice for high-heat environments. It maintains its appearance with regular maintenance. Check the finish details in the product specifications to ensure it matches your aesthetic preferences. Durable materials extend the lifespan of your cooktop and reduce long-term upkeep needs.
