An outdoor kitchen is one of the few home projects where the expensive mistakes are made before anyone breaks ground. Once the masonry cures around a grill cutout that is an inch too narrow, or the gas line is trenched to the wrong side of the patio, the fix is demolition rather than adjustment.
The good news is that nearly every one of those mistakes is avoidable with an afternoon of planning. Here is the sequence that keeps a build on track, from deciding where it goes to choosing appliances that actually fit the island you are about to pour.
If you are already comparing appliance sizes, start with the Built-In Grills collection so the equipment can drive the island dimensions rather than the other way around.
Quick Takeaways
- Choose appliances before the island is designed, not after. Cutout dimensions drive the framing.
- Plan for three zones: hot, cold, and prep. Skipping prep space is a common compromise that reduces usable workspace.
- Utilities are an early decision. Gas, electrical, and drainage choices can affect framing and trade work.
- Covered and partially enclosed spaces require extra attention to the appliance manual, ventilation, clearances, and local code.
Start With Placement, Not Product
Before you look at a single grill, walk the space and answer four questions.
- Where does the smoke go? Consider prevailing wind and keep smoke movement away from seating areas, doorways, and nearby windows where practical.
- How far is the kitchen door? Think about the path between indoor storage, the outdoor cooking surface, and serving areas. Shorter, clearer routes generally make the space easier to use.
- What is underfoot? Built-in islands need a stable, level, load-bearing base appropriate for the planned structure and appliances.
- Where is the sun at dinner time? Afternoon sun can materially affect comfort at the cooking station, so shade and orientation belong in the early layout discussion.
The Three-Zone Layout
Outdoor kitchens are easier to plan when the major functions are separated into cooking, cold storage or beverage service, and prep space.
- The hot zone. Grill, griddle, side burner, and anything else that produces heat. This anchors the layout and should be placed with the appliance's clearance and ventilation requirements in mind.
- The cold zone. Refrigeration, ice storage, and beverage service. Separating these from the primary heat source can improve workflow and keeps guests from crowding the cook.
- The prep zone. Uninterrupted counter space for landing platters, resting food, and staging ingredients.
A practical starting point is to leave landing space on both sides of the primary grill, then increase the prep run if the overall island allows. Final dimensions should reflect the appliances, serving style, and available footprint.
Size the Grill to the Cooking, Not the Island
The temptation is to fill the space. A better approach is to match burner count and cooking surface to how you actually cook, then design the island around that decision.
| Typical Use | Grill Size | Planning Consideration |
|---|---|---|
| Couple, occasional guests | 26 in. / 3 burner | Compact footprint for smaller runs and everyday cooking |
| Family, regular entertaining | 32 in. / 4 burner | More room for separate heat zones and mixed cooking |
| Frequent large gatherings | 40 in. / 5 burner | More primary cooking area and room for larger loads |
For a compact run, the Kokomo 26-inch 3-burner keeps the footprint tight. A 32-inch 4-burner suits many family builds, and the 40-inch 5-burner gives entertaining-focused kitchens more primary cooking area.
Let the grill determine the opening
The Kokomo 32-inch Professional Built-In Gas Grill is a good example of why nominal grill width and island cutout are different measurements. Choose the appliance, then build from its current installation specifications.
Cutout Dimensions Are Not Product Dimensions
A grill described as 32 inches is not a 32-inch hole. Built-in appliances have specified cutout dimensions and installation requirements that account for the way the appliance sits in the island.
Pull the current installation manual for every built-in appliance before the island is framed, and give those dimensions to the builder. Do not assume an insulated jacket makes an otherwise non-compliant enclosure acceptable. Kokomo's current installation guidance for its built-in grills says not to install the grill into combustible enclosures; follow the exact model manual, required clearances, ventilation instructions, and local code before construction.
Build the Supporting Cast
Once the primary cooking appliance is chosen, the rest of the island can be planned around it.
- Refrigeration. Use a refrigerator that is specifically rated by its manufacturer for the intended outdoor installation and operating conditions.
- Beverage service. A drop-in ice bin can create a separate self-service area away from the primary cooking zone.
- A second cooking surface. A built-in gas griddle adds a flat cooking surface for breakfast, burgers, vegetables, and other foods that benefit from a plancha-style surface.
- Searing and rotisserie. An infrared sear burner or a rotisserie kit can expand the cooking methods available from the island when compatible with the selected grill.
- Charcoal or ceramic. Some cooks want live fire alongside gas. A built-in charcoal grill or ceramic kamado can create that second fuel option.
Plan refrigeration before the cabinet opening is finished
Refrigerators have their own dimensional, ventilation, electrical, and installation requirements. Treat them as built-in appliances to be planned early, not as empty cabinet space to fill later.
Decide on a griddle before utilities are finalized
A built-in griddle changes the appliance footprint and adds another gas connection to the project. If it belongs in the plan, include it while the utility layout and island framing are still flexible.
Utilities and Structure
- Gas. Natural gas and propane installations must follow the appliance requirements and local code. Have qualified trades size and install gas service where required.
- Electrical. Plan weather-appropriate outdoor electrical service and follow the appliance manual and local electrical code. Refrigeration, lighting, rotisserie motors, and convenience outlets can all affect circuit planning.
- Water and drainage. A sink adds supply, drainage, and climate-specific maintenance considerations. Decide whether it materially improves the way you will use the kitchen before adding that utility work.
- Overhead cover. Kokomo's current manuals specify outdoor use and require adequate ventilation. For a covered or partially enclosed setup, follow the exact appliance manual and consult the authority having jurisdiction if there is uncertainty about whether the installation qualifies.
- Permits. Requirements vary by jurisdiction. Confirm what applies locally before scheduling trades or permanent construction.
Protecting the Investment
For any outdoor appliance, verify the manufacturer-rated materials, finish, care instructions, and exposure limits for the exact model. Kokomo's current built-in grill pages for the models featured in this guide specify 304 stainless construction, but material grade is only one part of outdoor suitability.
A fitted canvas cover can help reduce direct exposure to outdoor debris and light moisture between uses; it does not replace normal cleaning, inspection, or manufacturer care.

Frequently Asked Questions
How much counter space does an outdoor kitchen need?
There is no single universal dimension. Plan landing space around the primary cooking appliance plus a dedicated prep area, then adjust the run for the exact appliance manuals, serving style, traffic flow, and available footprint.
Should I choose natural gas or propane?
Natural gas can eliminate tank changes but requires permanent gas service sized and installed for the appliance load. Propane changes the fuel-storage and access requirements. Decide the fuel type before ordering because the appliance configuration and installation requirements can differ.
Do built-in grills need an insulated jacket?
Do not use an insulated jacket as a substitute for the grill manufacturer's enclosure requirements. For Kokomo built-in grills, current installation guidance says not to install the grill into combustible enclosures. Follow the exact model manual, clearances, ventilation requirements, and local code.
Can I put an indoor refrigerator in an outdoor kitchen?
Use a refrigerator rated by its manufacturer for the intended outdoor installation and operating conditions. Indoor-only equipment should not be assumed suitable for outdoor use.
What is the most common outdoor kitchen planning mistake?
One of the most expensive mistakes is finalizing the island before the built-in appliances are selected. Appliance cutouts, clearances, ventilation, and utility locations should inform the framing before permanent construction.
