- Solid 304 stainless build with included LP-to-NG conversion
- Cutout footprint runs tight; measure twice before drilling
What's inside
When you are finalizing an outdoor kitchen build, the main grill is the obvious purchase decision, but the side burner quietly determines whether you actually use that island on a Saturday evening or just admire it from across the yard. A good built-in side burner lets you drop a saucepan, boil corn, toast buns, or sear a steak without stepping back inside. A bad one gives you uneven flame, rust spots within two seasons, and a cutout that does not sit flush against your stonework.
Over the past several months we installed, lit, and ran a range of built-in side burners across propane and natural gas setups, checking BTU output consistency, grate durability, corrosion resistance after repeated wash cycles, and how cleanly each unit dropped into a standard 12-to-16-inch cutout. The best built in side burners in this roundup all share one trait: they treat drop-in fit and material quality as non-negotiables rather than afterthoughts. Price differences in this category often map directly to those fundamentals, which is why we ranked them after real use rather than spec-sheet reading.

How We Picked
We scored each unit on four criteria that matter most in daily use: flame consistency across the grate surface (not just peak BTU), stainless steel grade and weld quality as a proxy for longevity in humid or coastal climates, drop-in cutout accuracy relative to published dimensions, and ease of conversion between fuel types when the spec sheet claims both. We also flagged units where the LED accent light introduced a wiring point that could corrode over time, because that is a failure mode nobody mentions in marketing copy.
The 8 Best Built In Side Burners in 2026
VEVOR Double Grilling Side Burners, 2 x 17,000BTU (LED)
This unit is the obvious answer for anyone who wants twin high-output burners without spending a premium. Two 17,000 BTU burners let you run a full saucepan and a cast-iron skillet at the same time, and the 304 stainless housing held up well through our salt-spray test without visible pitting. The LED ring adds a clean look for evening cookouts, though it is a cosmetic addition rather than a functional one. Conversion to natural gas is included and straightforward. The main drawback is that the cutout dimensions are slightly aggressive compared to some competitors, so verify your island opening before committing.
- Twin 17,000 BTU burners for simultaneous cooking tasks
- Solid 304 stainless build with included LP-to-NG conversion
- Cutout footprint runs tight; measure twice before drilling
VEVOR Single Grilling Side Burner, 15,000BTU
At under $180, this is the entry point for a single built-in side burner that still uses 304 stainless and handles liquid propane at a respectable 15,000 BTU. It converts to natural gas too. We used it mainly for sauce-warming and quick boil tasks, and the flame coverage was adequate for a 10-inch pan but started to thin at the edges with a 12-inch skillet. The grate feels lighter than premium competitors, which is acceptable at this price. Skip it if your cooking plan demands wide, even heat or if your island is in a high-wind zone where a shorter flame can get disrupted.
- Lowest price for a 304 stainless LP-to-NG convertible burner
- 15,000 BTU is sufficient for sauces, sides, and quick boils
- Grate stability and edge flame coverage weaken on larger pans
VEVOR Single Grilling Side Burner, 17,000BTU (LED)
This model sits between the 15,000 BTU and the double-burner options, adding two thousand extra BTUs and an LED accent for a few dollars more. In practice the higher output helped maintain a rolling boil in a full stockpot on a breezy day, which the 15K unit struggled with. However, this is the one product in our test group that earned the lowest rating at 3.5 out of 5, and our experience matched that score. The LED wiring housing felt less sealed than it should, and we noticed a faint burner-clicking delay on cold starts. If the LED is not important to you, the 15K version is a safer pick.
- 17,000 BTU handles a full stockpot without losing temperature
- LED ring gives a modern island look at minimal cost
- Build quality and ignition consistency lag behind the lineup
Stanbroil Built-In Single Side Burner, 12,000 BTU (Natural Gas)
Stanbroil targets the dedicated natural gas audience, and the 12,000 BTU output is honestly modest. Where this unit earns its place is the protective lid, which is rare at this price point and genuinely useful for keeping debris and moisture off the grate between uses. The 304 stainless and rust-resistant coating survived our six-week outdoor exposure test without discoloration. Drop-in installation was clean and matched published specs. The lower BTU rating means it suits simmering and warming more than aggressive searing, so think of it as a dedicated sauce station rather than a second grill.
- Includes a protective lid that most competitors omit
- Rust-resistant finish held up in coastal humidity testing
- 12,000 BTU limits it to simmer and warm tasks
Blaze Grills 12,000 BTU LTE Single Side Burner (Natural Gas)
Blaze carries a premium brand name, and at $431 you pay for that reputation. The LTE line shares the same stainless fabrication and fit-and-finish standards as their grills, so if you are building a full Blaze island this integrates seamlessly in both look and warranty coverage. The 12,000 BTU output is identical to the Stanbroil above, which makes the price gap hard to justify on performance alone. Build quality and weld consistency were excellent. Choose this if you already own Blaze grills and want uniform aesthetics and a single warranty contact, not because it outperforms cheaper rivals in BTU delivery.
- Premium stainless fabrication with consistent weld quality
- Integrates with full Blaze island and warranty ecosystems
- 12,000 BTU output at nearly double the Stanbroil price
Double Grilling Side Burners, 2 x 17,000BTU (Heavy Duty)
At $500 this is the most expensive dual-burner option in our lineup, but the “duty heavy” 304 stainless is noticeably thicker than the VEVOR double we tested first. We could flex the grate assembly less under pressure, and the overall unit weight gave it a more permanent, built-in feel rather than a bolt-on. Both burners hit a clean 17,000 BTU and conversion to natural gas is included. The tradeoff at this price is that you are getting no LED accents or protective lid, and the cutout is wide, so plan your island layout around it early rather than retrofitting into an existing opening.
- Thicker 304 stainless with a notably rigid grate assembly
- Dual 17,000 BTU burners with full LP-to-NG conversion
- Wide cutout demands early island planning, not retrofit
Double Grilling Side Burners, 2 x 15,000BTU (NG Kit)
This model costs the same $500 as the 17K heavy-duty double above but trades two thousand BTUs per burner for an included natural gas conversion kit and the same thick-gauge stainless build. In our testing the 15,000 BTU burners were plenty for side dishes and a simmer station, and the NG kit made the dual-fuel transition faster than the VEVOR process. However, the price-for-BTU ratio is worse than almost any other option here. Unless your kitchen runs exclusively on natural gas and you want a heavy stainless double, the 17K version delivers more for the same money.
- Natural gas kit included for a smoother fuel transition
- Heavy-duty 304 stainless matches the pricier 17K double
- Only 15,000 BTU per burner at the same $500 price
Built-in Single Side Burner, 15,000 BTU (Brass Cap, 8mm Grate)
This is the sleeper of the group and our highest-rated single burner at a perfect 5 out of 5. The brass burner cap is the key differentiator: brass distributes heat more evenly than stamped steel and resists warping under repeated high-heat cycles. The 8mm reinforced grate flexed almost zero under our foot-pressure test, which is unusual at this price. It runs both natural gas and propane out of the box. The 15,000 BTU output is mid-range, but the consistent flame pattern across the full grate surface made it feel more powerful than the spec suggests. For a single built-in side burner under $300, nothing else in this group matched its overall build quality.
- Brass burner cap and 8mm reinforced grate outlast steel rivals
- Dual fuel (NG and propane) supported without separate conversion
- Minimal brand presence; replacement parts may be harder to source
Buying Guide
Cutout Fit and Drop-In Tolerance
Built-in side burners are not universal. Each unit has a specific cutout dimension, and most published numbers describe the opening, not the visible trim. Measure your existing island hole or plan your masonry cut before purchasing, and leave at least a quarter-inch of adjustment tolerance so you can shim or trim without re-cutting stone. A unit that does not sit flush will trap moisture against your island face and accelerate corrosion at the weld seams.
Burner Material and Flame Coverage
Stamped steel burner caps are common in budget units and warp over time, creating hot spots and cold zones. Brass caps cost more but maintain their shape through thermal cycling, giving you even flame coverage across the grate. If a product does not specify the cap material, assume stamped steel and plan on replacing it within two or three seasons. Pair the material with grate thickness, since an 8mm or thicker grate prevents the pan from tipping when you shift a heavy stockpot toward the back of the burner.
Fuel Type and Conversion Realism
Many listings claim dual fuel support but only include the conversion kit on one fuel variant. Verify which gas the unit ships with by default, and confirm whether the opposing conversion kit is included or costs extra. If your island is plumbed for natural gas and the burner ships as propane-first, budget for the conversion parts and check that the orifices are accessible without removing the entire burner housing.
Our Verdict
Our top pick for most buyers is the Built-in Single Side Burner with the brass cap at $269.99. It has the best materials at its price point, dual fuel without conversion hassle, and a perfect 5 out of 5 rating that our own testing confirmed. The 15,000 BTU output is more than enough for the sauce-and-side role a single burner fills in a well-planned outdoor kitchen.
For budget buyers who need a side burner today and can wait for replacement parts if something wears out, the VEVOR 15,000 BTU single at $175.9 is the lowest-risk entry into the category. It is not the most refined, but the stainless build and included conversion keep it functional for several seasons.
If you are building a full island and want two burners from the start, the VEVOR Double 17K at $295.9 gives you 34,000 total BTUs for nearly $200 less than the premium heavy-duty double. You sacrifice grate rigidity and thicker steel, but the output and fuel flexibility match what a working cookout actually requires.
FAQ
How many BTUs does a built-in side burner actually need?
For boiling water, simmering sauces, and heating side dishes, 12,000 to 15,000 BTU is sufficient and most buyers never need more. If you plan to sear proteins in a cast-iron skillet or run a full stockpot simultaneously with the main grill, aim for 17,000 BTU per burner or go dual.
Can I convert a propane side burner to natural gas myself?
Yes, most units in this category ship with a conversion kit that replaces the orifice and adjusts the regulator. The job requires a wrench and a few minutes per burner, but if you are uncomfortable working with gas fittings, have a licensed technician handle the connection at the supply line for safety.
Is 304 stainless steel really necessary, or will 430 last as long?
430 stainless is magnetic and contains less nickel, making it more vulnerable to surface rust in humid or coastal environments. 304 stainless resists chloride corrosion significantly better. If your outdoor kitchen is in a region with regular rain, snow, or salt air, the upgrade to 304 is the single best material decision you can make in this category.
What is the best way to protect a side burner between uses?
A fitted protective cover blocks rain and UV from the grate and burner housing, and a built-in lid like the one on the Stanbroil model keeps debris out of the flame ports. Either approach prevents the two most common failure modes: clogged orifices from insect nests and surface rust from standing water under the grate.
