Cooktops

An outdoor kitchen cooktop runs on natural gas or propane and delivers 15,000-50,000 BTU per burner — enough power to sear, wok-cook, and boil at restaurant speed outdoors. Shop drop-in gas cooktops and electric models from NXR, ZLINE, and Summit, sized for 24″ to 36″ outdoor kitchen cutouts.

Gas vs. Electric Outdoor Kitchen Cooktop

The choice between gas and electric comes down to one factor: fuel availability. A natural gas outdoor kitchen cooktop connects directly to your home gas line and delivers unlimited cook time with no tank management. A propane model gives you the same BTU output wherever you run a line. An electric radiant cooktop (230V) works where no gas line runs but requires a 240V circuit within reach of the outdoor kitchen frame.

Gas Outdoor Cooktops (Natural Gas & Propane)

The NXR 36″ Pro-Style Cooktop SCT3611 ($1,030 natural gas) and SCT3611LP ($1,734 propane) are the benchmark sealed-burner outdoor options. Sealed burners sit in a recessed bowl and resist grease, rain, and debris better than open-burner designs. Critical spec: the NXR runs 18,000 BTU on its power burner and 650 BTU on simmer. For searing protein at 700F+ grate temperature, that power burner output is the number that matters. The ZLINE 36″ 6-Burner Drop-In RC36 ($773) covers the same 36″ cutout at a lower price with brass burners across all six positions.

Electric Outdoor Cooktops (Radiant 230V)

The Summit 4-burner ($481) and 5-burner ($975) radiant cooktops fill the no-gas-line scenario. Installed with a GFCI-protected 240V circuit, a radiant cooktop delivers consistent, dial-controlled heat appropriate for sauce work, side dishes, and extended low-temperature cooking.

BTU Guide — What You Need by Cooking Style

BTU measures how much heat a burner produces per hour. Outdoor kitchen cooktops run hotter than indoor ranges, and that extra heat matters differently depending on what you cook.

15,000-20,000 BTU: Standard Outdoor Burner

Sufficient for boiling water (8-quart pot in 9-12 minutes), sauteing vegetables, and maintaining rolling heat on a large wok.

25,000-35,000 BTU: High-Output Power Burner

Reduces 8-quart boil time to 5-6 minutes. Required for deep-frying (maintains oil temp when cold food is added), high-heat wok cooking, and rapid crust formation on fish or scallops.

40,000-50,000 BTU: Commercial-Grade Output

Verify BTU-to-burner-diameter ratio before specifying a high-BTU unit. A properly calibrated 18,000 BTU burner with good flame spread often outperforms a 50,000 BTU burner with poor pot-to-flame contact for most outdoor cooking tasks.

Installation Checklist Before You Order

Cutout Dimensions

Standard sizes: 24″, 27″, 30″, 36″. Measure the inside opening of your outdoor kitchen frame. The NXR and ZLINE 36″ models both specify a 35.5″ x 20.5″ cutout. Allow 1/8″ clearance per side per manufacturer spec.

Gas Line Access

Natural gas: requires a dedicated shutoff valve within 3 feet of the cutout. Propane: requires a regulator-equipped line with adequate BTU capacity for total appliance load. All gas connections must be made by a licensed plumber or gas fitter in most US jurisdictions.

Electrical (Electric Models)

Summit radiant cooktops require a dedicated 240V/30A GFCI-protected circuit. Outdoor electrical must use weatherproof conduit rated for wet-location per NEC 406.9.

Frequently Asked Questions

What is the best outdoor kitchen cooktop for a built-in installation?

For a permanent built-in outdoor kitchen, the NXR SCT3611 (natural gas) is the top pick: sealed burners, stainless finish rated for outdoor exposure, and a 36″ width fitting standard outdoor kitchen frame openings. For propane, the SCT3611LP delivers identical performance. The ZLINE RC36 offers more total burners (6 vs 5) at a lower price point.

How much does an outdoor kitchen cooktop cost?

Entry-level 4-burner electric: $481 (Summit). Mid-range 6-burner gas: $773 (ZLINE RC36). Premium sealed-burner gas: $1,030-$1,734 (NXR SCT3611). Budget $200-$500 additional for professional gas line connection.

Can you use an indoor gas cooktop outdoors?

Not recommended. Indoor cooktops are not rated for rain, humidity, UV, or temperature cycling. Outdoor-rated cooktops use sealed ignition systems, corrosion-resistant alloys, and weatherproof gaskets. Using an indoor cooktop outdoors voids the warranty and creates safety hazards from corroded gas valves.

What size outdoor kitchen cooktop do I need?

A 36″ 5-6 burner unit handles two-zone cooking (high heat + simmer simultaneously) for 6-12 people. A 30″ 4-burner works for everyday family grilling. Under 30″ is adequate for a prep station, not a primary cooking surface for entertaining.

How long does an outdoor kitchen cooktop last?

Properly maintained stainless steel outdoor cooktops — cleaned after each use, covered when not in use, gas valves closed at the manifold — realistically last 10-15 years in temperate climates. In coastal or high-humidity environments, prioritize 304 stainless steel over 430, and rinse salt deposits after storms.
