The Kokomo 40-inch Professional Built-In Grill is a five-burner gas grill designed for larger outdoor-kitchen installations. Its strongest buying case is straightforward: 304 stainless construction, cast stainless burners, five independently controlled zones, lighting, LP or natural-gas configurations, and a documented built-in cutout.
This review focuses on the current manufacturer specifications and the installation questions that matter before you give a fabricator the final dimensions.

What you are actually getting
Kokomo currently lists the 40-inch Professional Built-In Grill as completely constructed from 304 stainless steel. The model uses five heavy-duty cast stainless burners, an infrared rear burner, stainless and ceramic flame-tamer sets, an adjustable warming rack, a full-size drip tray, heat-zone dividers and multiple lighting features.
For buyers comparing large built-in gas grills, the combination of five independently controlled burners and a 920-square-inch cooking surface is the main reason to consider this size.

Five burners are most useful when you use them as separate zones
The Professional model includes heat-zone dividers between the burners. That matters more than simply having five control knobs: it gives you more flexibility to establish hotter and cooler areas across a large cooking surface.
Cast stainless burners
The Professional model uses heavy cast stainless main burners rather than the pipe-style burners listed on Kokomo’s Classic 40-inch model. The distinction is worth checking when you compare the two product lines.
Two flame-tamer approaches
Kokomo lists both stainless steel and ceramic flame-tamer sets with the Professional grill. That gives the owner flexibility in how heat is diffused above the burners.
Infrared rear burner
The rear burner is intended to support rotisserie-style cooking when paired with the appropriate rotisserie equipment. Confirm which accessories are included versus optional at the time of purchase.
Full-size drip tray
A front-accessible stainless drip tray is part of the current feature list, making grease management easier to include in a regular cleaning routine.

Lighting is one of the real differences in the Professional line
The current 40-inch Professional listing includes interior oven lights, illuminated knobs and a hood light that illuminates when the hood is open.
If your outdoor kitchen will be used after sunset, plan the required electrical service before cabinetry and countertops are finished. The current installation documents should control the final electrical requirements.
The cutout is 38″ × 8⅝″ × 21¼″
Kokomo currently lists a 38-inch cutout width, 8⅝-inch cutout height and 21¼-inch cutout depth for the 40-inch Professional grill. The grill body is larger than the opening because Kokomo uses a perimeter flange around the built-in head.
- Choose the grill before cutting the island. Do not size the opening from the advertised 40-inch product name.
- Use non-combustible island construction. Kokomo’s current installation guidance calls for a non-combustible BBQ island.
- Plan combustible clearances from the current manual. The manual contains model-specific clearance guidance that must be reconciled with local code.
- Use qualified gas installation. Gas type, shutoff access and leak testing should be handled according to the manufacturer instructions and applicable code.
- Plan for the listed 172-pound appliance weight. Delivery to the property and placement into the island are separate steps.

Who should consider the Kokomo 40 Professional?
Good fit if…
- You are building a larger permanent outdoor kitchen.
- You want five independently controlled main burners.
- You want 304 stainless construction documented by the manufacturer.
- You value built-in lighting for evening cooking.
- You need either LP or natural-gas configuration.
Consider another format if…
- Your existing opening is substantially smaller than the required cutout.
- You prefer charcoal or live-fire cooking over gas.
- You need a portable or freestanding appliance rather than a built-in head.
- Your project cannot support the required non-combustible enclosure and utility planning.
Separate included features from add-ons
Kokomo’s current product page lists a sear burner, rotisserie kit and griddle insert as optional upgrades. They should not be treated as included unless the exact configuration you are purchasing says otherwise.
This distinction matters on high-ticket grills because accessory assumptions can change the real project cost and the cooking setup you expect on delivery.

A strong candidate when a large 304-stainless built-in gas grill fits the project
The Kokomo 40 Professional makes the most sense when you actually need a 40-inch built-in footprint, five-burner zoning, lighting and the current Professional feature set. The decision should be driven by the island dimensions and cooking style—not by the word “Professional” alone.
