Our Picks: Best Gas Barbecue Grills With Lava Rocks reviews
Atosa ATCB 48-Inch: A Wide Charbroiler With Four Independent Burners
The Atosa ATCB is a wide commercial charbroiler designed for kitchens that need room to cook several items at once. It has four stainless steel burners rated at 35,000 BTU each, with independent manual controls. Separate controls give you the option to manage different areas of the grill rather than treating the entire cooking surface as one heat zone.
Its reversible cast-iron top grates are adjustable for multi-level charbroiling. The product information also describes a lava-rock grate, along with a stainless steel interior and exterior. It is configured for natural gas and includes an LP conversion kit, though any fuel conversion and installation should follow the manufacturer’s instructions and local requirements.
This is a substantial commercial appliance, not a portable backyard grill. Its width calls for a compatible counter and adequate kitchen space. For a smaller operation, the footprint may be more than you need; for a busy kitchen, the four burners and broad surface offer more flexibility than the compact options below.
Pros:
- Four independently controlled burners for managing heat by area
- Wide cooking surface for higher-volume service
- Adjustable, reversible cast-iron grates
- LP conversion kit is included with the natural gas configuration
Cons:
- Requires substantial counter space and a suitable commercial gas setup
- Its size may be unnecessary for low-volume cooking
Verdict: Choose this Atosa if you need a large commercial charbroiler with multiple burner controls; skip it if you want a compact or freestanding home grill.
Atosa CookRite ATCB-24: A Smaller Lava Briquette Countertop Model
The ATCB-24 is a 24-inch commercial countertop charbroiler that uses lava briquettes to absorb and retain heat from the gas flames. The manufacturer says the briquettes help spread heat across the cooking area and catch drippings, which can create smoke and flare-ups as food cooks.
The stainless steel finish is intended for commercial kitchen use, and adjustable steel legs can help level the unit on a suitable counter. Compared with the 48-inch Atosa models, this one takes up less space, but the narrower cooking area also limits how much you can cook at once.
The supplied product information marks this model unavailable, so check the listing before making plans to purchase it. As with other commercial countertop units, confirm your gas connection and installation requirements rather than assuming it will work with a standard home setup.
Pros:
- More compact than a 48-inch charbroiler
- Lava briquettes help retain and spread heat
- Adjustable legs help with leveling on a suitable counter
- Stainless steel finish suits commercial kitchen settings
Cons:
- Smaller cooking area than the 48-inch models
- The supplied product data marks it unavailable; confirm listing status
Verdict: Consider the ATCB-24 if you need a compact commercial lava-briquette charbroiler and can confirm it is available; its smaller surface is a poor fit for high-volume cooking.
Atosa CookRite ATCB-48: A Wide Lava Briquette Grill for Commercial Counters
This 48-inch CookRite model uses lava briquettes to absorb and radiate heat across its cooking surface. The briquettes also catch drippings, which can contribute to smoke and flare-ups. That may appeal to cooks looking for a charbroiled style, but it also means you should pay attention to cleaning and safe operation.
It has a stainless steel exterior and adjustable steel legs for leveling on a commercial counter. The broad cooking area is the main reason to choose it over the 24-inch CookRite: it gives you more room for simultaneous cooking, but also requires more counter space. The supplied product details do not list burner count or BTU output, so compare those specifications with your needs before ordering.
This model is best considered for an equipped commercial kitchen rather than a casual outdoor setup. Verify the fuel configuration and installation instructions on the listing, since the provided product details do not specify a conversion kit for this model.
Pros:
- Wide cooking surface for commercial use
- Lava briquettes retain and distribute heat
- Stainless steel construction
- Adjustable legs help with leveling
Cons:
- Needs more counter space than the 24-inch model
- Burner count and BTU output are not specified in the supplied details
Verdict: Pick the ATCB-48 if you want a wide lava-briquette charbroiler and have room for a commercial countertop unit; compare its full specifications with the four-burner Atosa ATCB before deciding.
STEELBUS 24-Inch: A Two-Burner Charbroiler With 56,000 BTU Output
The STEELBUS is a 24-inch countertop charbroiler with two U-shaped burners and a stated total output of 56,000 BTU. Its lava-rock system is designed to absorb, retain, and radiate heat, while reversible cast-iron grates provide the cooking surface. Independent burner controls are not specified in the supplied details, so check the product listing if separate zone adjustment matters to you.
The unit is made from stainless steel and has insulated double-wall sides, according to the product description. It is configured for natural gas and includes propane conversion accessories. The description also lists an ETL certification and a removable grease tray. These features make it a compact commercial option, but you should still confirm the certification details, connection, and installation requirements for your location.
The supplied product information marks this model unavailable. If the listing becomes accessible, its stated burner output and fuel-conversion accessories may make it worth comparing with the smaller Atosa model. Its 24-inch width is easier to accommodate than a 48-inch grill, but it remains a commercial appliance rather than a portable patio barbecue.
Pros:
- Two U-shaped burners with 56,000 BTU stated output
- Reversible cast-iron grates and lava-rock heating system
- Natural gas setup with propane conversion accessories included
- Removable grease tray for cleanup
Cons:
- The supplied product data marks it unavailable; verify listing status
- Still requires a compatible commercial counter and gas installation
Verdict: The STEELBUS is a promising compact commercial option on paper, but confirm that it is available and that its connection and installation requirements fit your kitchen.
FammyLoft 12-Inch: A Space-Saving Single-Burner Lava Rock Grill
The FammyLoft is the narrowest option in this group, with a 12-inch countertop format and one burner rated at 28,000 BTU. Its lava-rock system is intended to retain and spread heat, while cast-iron grates provide the cooking surface. The manufacturer describes it as suitable for settings such as food trucks, pop-ups, and small kitchens where counter space is limited.
It is built with stainless steel and is configured for natural gas, with propane conversion mentioned in the product information. The description also lists a standard 3/4-inch NPT gas connection and a removable grease tray. Confirm the exact installation and conversion steps before use; gas connections and fuel changes should be handled according to the manufacturer’s directions and applicable local rules.
The compact size is its main advantage, but it also means less room to cook than the 24- and 48-inch models. The single burner may suit small batches or a limited menu, but it is not the best choice when you need to cook many items at once. Its commercial design also means it should not be confused with a freestanding residential barbecue.
Pros:
- Compact 12-inch width for space-constrained counters
- 28,000-BTU burner for searing and grilling
- Lava-rock heating with cast-iron grates
- Natural gas setup with propane conversion described
Cons:
- Limited cooking area compared with the wider models
- One burner offers less flexibility for separate cooking zones
Verdict: Choose the FammyLoft if counter space is your top concern and you only need a compact commercial charbroiler; choose a wider model for more simultaneous cooking.
How to Choose a Gas Charbroiler With Lava Rocks
Decide whether you need a commercial countertop unit
All five picks are described as commercial charbroilers, and none is presented as a freestanding backyard grill with a cart. Before comparing features, decide where the appliance will go and whether your space is set up for a commercial countertop unit. Check the required counter support, ventilation, clearances, and installation instructions for the specific model.
Match the grill width to your cooking volume
The options range from a compact 12-inch unit to 48-inch models. A smaller grill can make sense for a food truck, small operation, or limited menu, while a wider surface offers more room for cooking multiple items at once. Measure your available counter space and leave room for the clearances required by the manufacturer.
Compare burner layout and heat controls
Burner count and controls affect how you manage heat across the cooking surface. The Atosa ATCB 48-inch model lists four independently controlled burners, while the STEELBUS lists two U-shaped burners. The FammyLoft has one burner. For the two CookRite models, the supplied details do not give burner counts, so check the full specifications if burner layout is a deciding factor.
Understand what the lava rocks do
Lava rocks or briquettes absorb and hold heat, then radiate it toward the cooking surface. They can also catch drippings, which may create smoke and flare-ups. That can help produce a charbroiled cooking style, but it makes correct setup, cleaning, and safe operation important. Follow the manufacturer’s instructions for arranging and maintaining the rocks or briquettes.
Check fuel type and conversion details
Some of these grills are configured for natural gas and include propane conversion accessories or a conversion kit. Do not assume that a model supports both fuels just because another product in this list does. Verify the exact configuration, connection size, and conversion instructions for your chosen model, and use a qualified installer where required.
Look at grate material and cleaning access
Cast-iron grates are featured on several options, and some are reversible or adjustable. A removable grease tray, listed on the STEELBUS and FammyLoft models, can make routine cleanup easier. Before buying, check how the unit’s grates, tray, and lava-rock system are meant to be cleaned and maintained.
Verify installation, certification, and listing details
Commercial gas equipment needs a suitable connection and a safe installation. Confirm that the product’s specifications match your kitchen and local requirements. The STEELBUS description lists ETL certification; check the listing and product documentation for the certification details that apply to your use. Also confirm the current listing status and included parts before placing an order.
Frequently Asked Questions
Are these lava-rock grills suitable for a typical backyard?
These picks are described as commercial countertop charbroilers, not freestanding outdoor grills. If you want a patio barbecue, look for a model specifically designed for outdoor residential use, with a stand or cart and instructions for outdoor installation.
Do lava rocks make a gas grill cook more evenly?
Lava rocks absorb and radiate heat, which can help spread heat across the cooking area. Actual results depend on the grill design, burner layout, setup, and maintenance, so lava rocks alone do not guarantee perfectly even cooking.
Do lava rocks add a smoky flavor?
The product descriptions say the rocks or briquettes catch drippings and can create smoke and flare-ups. The amount of smoke and the flavor you get can vary with the food, heat, and grill setup.
Can I use propane with these grills?
Fuel options differ by model. The Atosa ATCB 48-inch is configured for natural gas and includes an LP conversion kit; the STEELBUS and FammyLoft descriptions also mention propane conversion accessories or conversion. Check the product details for each model and follow its conversion instructions rather than assuming all models support both fuels.
Which option is best for a small kitchen?
The FammyLoft is the most compact listed option at 12 inches wide, while the Atosa CookRite ATCB-24 and STEELBUS are 24-inch models. A smaller footprint means less cooking area, so measure your space and consider how much you need to cook at one time.
Are any of these models listed as unavailable?
The supplied product information marks the Atosa CookRite ATCB-24 and STEELBUS as unavailable. Availability can change, so check the product listing before relying on either model as an option.
Conclusion
For a commercial kitchen that needs broad capacity and multiple independently controlled heat zones, the Atosa ATCB 48-inch is the clearest fit in this group. If counter space is tight, the FammyLoft 12-inch offers the smallest footprint, while the 24-inch models provide a middle ground. Keep in mind that these are commercial countertop charbroilers, not standard backyard grills, and confirm fuel compatibility, installation needs, and listing availability before you buy.
