The best built-in natural gas grills include the BRANDMAN Brand-Man Built-In Gas Grill Head for large multi-zone cooking, the SPIRE 30" Built-In 5 Burner Dual Fuel for a compact built-in head, and the Blaze Prelude LBM Built-In Natural Gas Grill for a specified natural gas cutout.

4. Which built-in natural gas grill should you choose?

The best built-in natural gas grills depend on your island cutout and fuel connection. Blaze is a direct natural gas grill with published cutout dimensions; Brand-Man offers a larger cooking area but needs a separate conversion kit for natural gas.

For an outdoor kitchen, the fit is as important as the burner count. If a freestanding gas grill is a better fit, read our Weber Spirit E-310 review.

Measure the opening before choosing a grill head, and confirm that the model’s fuel setup matches the gas line you plan to use.

This roundup compares natural gas models and dual-fuel options by cooking area, burner layout and installation details. If you are still planning the island, see How To Build A Built In Gas Grill? and How To Build Outdoor Gas Grill? for build considerations.

BRANDMAN Brand-Man Built-In Gas Grill Head: Best for large multi-zone cooking

9.5/10Our score

• 6 burners
• 860 sq in total cooking space
• 60,000 BTU total burner output
• Natural gas conversion kit sold separately

The 6-burner layout and 860 sq in total cooking space suit larger outdoor kitchens. It starts as a propane grill, so natural gas buyers need to account for the separate conversion kit.

See it on Amazon

Pros

• Large total cooking area
• Cast iron grates and griddle plate
• Slide-out front grease tray

Cons

• Natural gas conversion kit sold separately
• Cutout width range requires careful measurement

Brand-Man suits an island designed for a broad grill head and several cooking zones. Its 860 sq in total cooking space includes a 620 sq in primary area with cast iron grates and a griddle plate, plus a 240 sq in warming rack.

Six burners provide 60,000 BTU total output, according to the stated specifications. The layout gives you separate zones for foods that need different heat levels, while the slide-out front grease tray makes drippings easier to remove.

This model operates on liquid propane and is described as natural gas convertible with a separate conversion kit. Its cutout range is 40.5–42.8 in wide, 16.7 in deep and 11.5 in high, so compare those measurements with your island plans before choosing it.

Pick Brand-Man for a large cooking area and multi-zone layout, provided you have the right cutout and confirm the conversion requirements for natural gas. For a propane setup, compare it with best propane grills for outdoor kitchens.

SPIRE 30" Built-In 5 Burner Dual Fuel: Best for a compact built-in head

9.1/10Our score

• 5 main burners
• 750 sq in total cooking space
• 13,000 BTU rear burner
• Stainless steel body and grates

This 30-inch class head pairs 5 main burners with a rear burner and 750 sq in of stated cooking space. Confirm the fuel configuration and required cutout before ordering.

See it on Amazon

Pros

• Rear burner adds cooking flexibility
• 304 stainless steel grates
• Stainless steel frame

Cons

• Cutout dimensions are not specified here
• Fuel configuration should be confirmed

The SPIRE 30-inch head fits buyers who want a built-in grill with a rear burner and a more compact width class. It has 5 main burners and 750 sq in of total cooking space, with a 13,000 BTU rear burner for rotisserie cooking or warming.

Its stainless steel frame and 304 stainless steel grates are designed for outdoor use. The listed overall dimensions are 34.05 in wide, 25.55 in deep and 23.07 in high, but the cutout measurements are not provided here.

The model is described as dual fuel, while its product title identifies it as a propane grill. Confirm that the exact unit can be configured for natural gas and ask for the required cutout dimensions before building around it.

Choose this SPIRE when the rear burner and 30-inch class size suit your plan. If you have not fixed the fuel line yet, compare natural gas with propane options and installation needs before choosing a grill.

Blaze Prelude LBM Built-In Natural Gas Grill: Best for a specified natural gas cutout

9.0/10Our score

• Natural gas model
• 4 burners with 56,000 BTU total output
• 740 sq in cooking area
• Removable heat zone separators

The Blaze is a natural gas model with cutout dimensions specified for planning. Its heat zone separators support cooking at different temperatures across the grill.

See it on Amazon

Pros

• Natural gas configuration
• Published cutout dimensions
• Flame stabilizing grids

Cons

• Smaller cooking area than the largest heads here
• Verify the island opening against the stated cutout

Blaze is the straightforward pick for buyers who want a built-in natural gas grill with a specified opening size. To compare other four-burner options, see four-burner gas grills.

Its 4 burners provide 56,000 BTU total output, and the cooking surface measures 740 sq in.

The cutout needs to measure 30 5/8 in wide, 21 1/4 in deep and 8 1/2 in high. Removable heat zone separators support different cooking temperatures, while flame stabilizing grids are designed to reduce flare-ups and spread heat.

Blaze states that the grill uses 304 stainless steel and backs it with a lifetime residential warranty and a 3-year commercial warranty. Review the warranty terms and installation instructions directly with Blaze before making the final decision.

Choose Blaze if its stated cutout fits your island and you want a natural gas model. For a broader comparison that includes freestanding options, see Best Natural Gas Grill.

SPIRE 36" Built-in 6 Burner Dual Fuel: Best for a wide cooking surface

8.8/10Our score

• 6 main burners
• 904 sq in total cooking space
• Rear burner
• Stainless steel body and grates

The widest SPIRE pick has 6 main burners and 904 sq in of stated cooking area. Make room for its 40-inch width and verify the natural gas setup before purchase.

See it on Amazon

Pros

• Largest stated cooking area in this group
• Six main burners plus a rear burner
• Stainless steel construction

Cons

• Cutout dimensions are not specified here
• Requires more width than the 30-inch class option

The SPIRE 36-inch head is for outdoor kitchens with room for a wider grill and a large cooking surface. It has 6 main burners, a rear burner and 904 sq in of stated total cooking space.

Its overall dimensions are 40 in wide, 25.2 in deep and 21.8 in high. The stainless steel body and grates suit an outdoor setup, and the rear burner adds another cooking area for rotisserie use or warming.

The model is described as dual fuel, but the available information does not guarantee its exact natural gas conversion method or cutout dimensions. Verify both with the manufacturer before committing to the island opening or gas connection.

Pick this SPIRE for a wide head and high stated cooking capacity, if the measurements work for your island. For a different build approach, read How To Build A Brick Gas Grill?.

Stanbroil 28-Inch Built-In Natural Gas Griddle: Best for flat-top meals

8.7/10Our score

• Natural gas powered
• 412 sq in cooking surface
• Two independently controlled burners
• 304 stainless steel

This drop-in griddle is a natural gas option for an outdoor kitchen built around a flat cooking surface. Two independently controlled burners let you set separate heat zones.

See it on Amazon

Pros

• Natural gas model
• Cutout dimensions provided
• Separate burner controls

Cons

• Flat cooking surface rather than grill grates
• Less cooking area than the grill heads

The Stanbroil is a built-in natural gas griddle for cooks who want a flat surface instead of grates. Its 412 sq in cooking area is heated by two H-shaped burners with a combined 34,000 BTU output.

The 304 stainless steel griddle has independently controlled burners, so you can set different heat levels across the surface. The stated cutout is 26 in long by 21.72 in wide and 7.16 in high.

A griddle handles foods such as eggs, pancakes, bacon and sandwiches that can be awkward on grill grates. It is a different cooking format from the four grill heads above, so choose it when a flat top suits your regular meals.

Choose Stanbroil for a natural gas drop-in griddle, not a grate-style grill head. Check the opening dimensions and make sure the flat surface is the cooking style you want.

How we compared built-in natural gas grills

We compared the stated fuel setup, cooking area, burner layout and cutout information for each option. Our score weighs specs and features against what shoppers looking for a built-in natural gas cooking surface need.

The most useful distinction is direct natural gas operation versus a model that needs conversion. For another brand to compare, see Napoleon natural gas grills.

Blaze and Stanbroil are natural gas models, while Brand-Man requires a separate conversion kit and SPIRE’s dual-fuel configuration should be confirmed for the exact unit.

Cutout details also vary. Blaze, Brand-Man and Stanbroil provide opening dimensions, while the SPIRE models’ cutout dimensions need confirmation before you build or order.

What should you check before choosing a built-in gas grill?

Check the cutout, gas connection and cooking style before comparing extra features. A grill that does not fit the island or fuel supply is not a practical choice, even if its cooking area looks right.

For cooking away from the island, compare portable propane grills.

How do you measure a natural gas grill built-in cutout?

Measure the opening’s width, depth and height at more than one point, since masonry or counters can vary slightly. Compare the smallest measurements with the required cutout size, not just the grill’s outer dimensions.

Brand-Man gives a cutout width range of 40.5–42.8 in, while Blaze specifies 30 5/8 in wide by 21 1/4 in deep and 8 1/2 in high. Stanbroil’s griddle opening is 26 in long by 21.72 in wide and 7.16 in high.

How can you confirm a dual-fuel grill is right for natural gas?

Ask the manufacturer whether the exact model supports natural gas and what conversion parts and installation steps it requires. “Dual fuel” alone does not tell you which parts are included or whether conversion is needed.

Brand-Man specifies a separate conversion kit. The SPIRE models are described as dual fuel, but their cutout dimensions and precise natural gas setup should be confirmed before purchase.

Do you want grill grates or a flat-top griddle?

Choose grill grates for searing and cooking foods directly over a grate surface. A flat top suits foods that need a solid surface, such as eggs, pancakes and chopped vegetables.

Stanbroil is the only griddle in this group. Its two independently controlled burners create separate heat zones on a 412 sq in surface, while the other options are grill heads.

Which built-in natural gas grill should you choose?

Choose Blaze if you want a natural gas grill head with published cutout measurements, or Brand-Man if your island has room for a much larger head and you are prepared to source its conversion kit. Pick a SPIRE model only after confirming the natural gas configuration and opening dimensions; choose Stanbroil when a flat-top surface fits your cooking.

If you are planning around a standard outdoor kitchen layout, use the cutout as your first filter. For a freestanding alternative, compare the Best Natural Gas Grill For Seniors guide for another natural gas buying perspective.

Frequently asked questions

What should I measure before buying a built-in natural gas grill?

Measure the cutout width, depth and height, then compare each with the grill's required opening dimensions. Also check the island's clearances and access for the gas connection against the grill and island instructions.

Do not rely on the overall grill dimensions alone, because the body and the cutout can have different measurements.

Can a propane built-in grill use natural gas?

Only if the manufacturer supports conversion for that model and the correct conversion kit is installed. Brand-Man describes its grill as natural gas convertible, with the conversion kit sold separately.

Confirm the exact model and installation requirements before connecting it to a natural gas line.

Is a built-in grill the same as a drop-in grill?

Both terms can describe a grill head made to sit in an outdoor kitchen island, but the required opening and installation details vary by model. Check the manufacturer's cutout dimensions and instructions before framing the island.

A drop-in griddle, such as the Stanbroil, has a flat cooking surface instead of grill grates.

Should I choose a natural gas grill or a griddle?

Choose a grill head if you want cooking grates and the option to use different heat zones across the surface. Choose a griddle if a flat top better suits foods such as eggs, pancakes, sandwiches and chopped vegetables.

The Stanbroil has a 412 sq in flat cooking area and two independently controlled burners.
