The short answer
For most homeowners, a prefabricated grill island (such as Bull Outdoor Products’ ready-to-finish islands) paired with a quality built-in gas grill head like a Blaze Premium LTE or Bull Outlaw is the fastest, most affordable path to an outdoor kitchen. If you want something modular you can rearrange or take with you, a stainless cabinet system like Napoleon OASIS is the better fit. Fully custom masonry islands give the most design freedom but cost the most and need a contractor.
Our picks at a glance
| Pick | Option | Type | Best for | Amazon |
|---|---|---|---|---|
| Best prefab island | Bull Outdoor Products BBQ islands | Prefab island, often sold with grill | Fast install, finished look | Amazon |
| Best built-in grill (value) | Blaze Premium LTE 32″ | Built-in gas grill head | Stainless build at a mid-range price | Amazon |
| Best built-in grill (alternative) | Bull Outlaw 30″ | Built-in gas grill head | Popular, well-supported grill head | Amazon |
| Best modular system | Napoleon OASIS | Modular stainless components | Flexible layouts, no masonry | Amazon |
| Best DIY modular | Stainless modular cabinets | Modular cabinets and countertops | Budget DIY builds | Amazon |
Large prefab islands are heavy, freight-shipped items. Check delivery terms, curbside vs. placement, and whether the grill is included before ordering.
How we picked
We compared manufacturer specifications, owner reviews and published guides on outdoor kitchen planning. We prioritized islands and grill heads that are widely sold, have available replacement parts, and use stainless steel components. We also weighed how much installation work each option requires, because that’s often the biggest hidden cost.
Three ways to build a grill island
| Approach | Pros | Cons |
|---|---|---|
| Prefab island | Arrives finished; quick install; matched cutouts | Limited layouts; heavy freight delivery |
| Modular stainless system | Rearrangeable; no masonry; expandable | Can look less “built-in”; premium systems cost more |
| Custom masonry or steel-frame build | Total design freedom; any finish | Highest cost; needs a contractor and permits |
1. Bull Outdoor Products BBQ islands — Best prefab
Bull is one of the best-known names in prefab outdoor kitchens. Its islands come in a range of sizes and finishes (stucco, stone veneer and others) and are commonly sold with a Bull grill head already fitted. A prefab island arrives as one piece or a few sections, so installation is mostly placing it, leveling it and connecting gas.
Good to know: islands are very heavy. Plan the delivery path and have enough help or equipment to move it.

2. Blaze Premium LTE 32″ — Best built-in grill head (value)
Blaze grills are a popular choice for custom islands because they offer stainless construction and strong warranties for the price. The Premium LTE line adds lighting and other upgrades over the base Blaze models. A 32-inch head with four burners is a common size for family cooking.
Good to know: confirm the cutout dimensions and whether you need an insulated jacket for a combustible island frame.

3. Bull Outlaw 30″ — Best built-in grill alternative
The Outlaw is one of Bull’s best-known built-in grill heads and is often used in Bull’s own islands. It’s a straightforward stainless grill with good parts support.

4. Napoleon OASIS — Best modular system
Napoleon’s OASIS line is a modular outdoor kitchen system: grill cabinets, sink, refrigerator and corner modules that bolt together in different layouts. It’s a good fit if you rent, may move, or want to start small and add modules later.
Good to know: component availability and configurations vary; check which modules fit together before ordering.

5. Stainless modular cabinets — Best DIY modular
Several brands sell stainless modular cabinets and countertops for outdoor kitchens. They’re the budget route to a built-in look, especially for DIYers who are comfortable leveling cabinets and running a gas line with a licensed pro.

Planning your layout
- Zones: plan for hot (grill, side burner), cold (fridge), wet (sink) and dry (prep counter) zones.
- Counter space: leave landing space on both sides of the grill for platters and tools.
- Utilities: gas (propane or natural gas), electrical for lights, rotisserie and fridge, and water if you want a sink.
- Clearances: follow the grill manufacturer’s clearance to combustibles, and never install under a low roof or overhang without proper ventilation.
- Ventilation: islands with an enclosed propane tank or gas line need vent panels to keep gas from collecting.
Add-ons worth considering
| Add-on | Why | Amazon |
|---|---|---|
| Access doors and drawers | Storage and access to gas connections | Amazon |
| Side burner | Sauces, sides, boiling | Amazon |
| Outdoor-rated refrigerator | Drinks and ingredients on hand | Amazon |
| Island cover | Weather protection | Amazon |
How big should your island be?
| Use | Typical setup | What it fits |
|---|---|---|
| Grill station | Island around 5–6 feet long | Grill head plus prep space on one side |
| Family outdoor kitchen | Around 8–10 feet, straight or L-shaped | Grill, side burner, storage, small fridge |
| Entertaining kitchen | L- or U-shaped with bar seating | Grill, side burner, fridge, sink, bar counter |
These are general planning ranges. Measure your patio, leave walkways at least a few feet wide around the island, and mock up the footprint with tape before ordering.
Gas, permits and safety
Built-in grills are sold for either propane or natural gas, and most need a conversion kit to switch. A natural gas line should be run by a licensed professional, and many areas require a permit for gas lines, electrical work and permanent structures. Test every connection with soapy water before first use. Install an access door so you can reach the shutoff valve. Keep a fire extinguisher nearby, and don’t build an island against vinyl siding.
Buying checklist
- Grill head: stainless (304-grade where available), with parts and warranty support.
- Cutout dimensions: match the grill to the island opening exactly.
- Insulated jacket: required for many grills in combustible frames.
- Fuel type: propane or natural gas, decided before you buy.
- Countertop: granite, concrete or tile that handles heat and weather.
- Delivery: freight terms, liftgate, and placement help.
- Permits: check with your city or HOA before you build.
FAQ
What is a grill island?
A grill island is a permanent outdoor counter with a built-in grill head, often with storage, side burners, a fridge or a sink. They’re sold prefabricated, as modular systems, or built custom.
Is a prefab grill island worth it?
For most homeowners, yes. Prefab islands arrive finished with matched cutouts, so installation is much faster and cheaper than a custom masonry build.
Do you need a permit for an outdoor kitchen?
Often, especially for natural gas lines, electrical work or permanent structures. Check with your city and HOA before you build.
Do built-in grills need an insulated jacket?
If the island frame is made of combustible material like wood, most manufacturers require an insulated jacket. Check the grill’s installation manual.
Propane or natural gas for an outdoor kitchen?
Natural gas is convenient if you already have a line and never runs out. Propane is easier to install. Decide before you buy because grills are configured for one fuel.
