A 48-inch gas range with a double oven is the kitchen powerhouse most home cooks only dream about — until they start shopping and realize the spec sheets are a maze of BTUs, cubic feet, and burner counts. The real question is simple: which of these hefty machines actually fits your cooking style, your counter depth, and your budget without driving you crazy with propane conversions or flimsy knobs? This guide breaks down the top four contenders by what matters most on a daily basis — oven capacity, burner power, and real owner experience.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you are upgrading from a standard 30-inch range or building a dream kitchen from scratch, the best 48 inch gas range with double oven is the one that balances cooking flexibility with honest, long-term durability.
Our Picks at a Glance
How To Choose The Best 48 Inch Gas Range With Double Oven
Stepping up to a 48-inch range changes how you cook. Before you dive into the models, here are the three factors that separate a great long-term purchase from a regret.
Oven Capacity and Cavity Layout
Double ovens are the whole point here. Some ranges give you one large main oven (4-plus cubic feet) and a smaller secondary oven for sides or warming. Others split the space more evenly. Think about your typical cooking: are you roasting a turkey while baking pies, or do you mostly need one big cavity and a small space for keeping plates warm? The total cubic feet number tells only part of the story — you need to know whether those cubic feet are shaped for a full-size sheet pan.
Burner Power and Flexibility
Not all BTUs (British Thermal Units — the measure of heat output) are the same. A range might boast a single 20,000 BTU burner but leave you with weak 6,000 BTU burners everywhere else. The best layout gives you at least one high-output burner (18,000+ BTU) for wok cooking or rapid boiling, plus a few medium burners and at least one low simmer burner for sauces. A center griddle burner is a bonus for pancakes or searing multiple items at once.
Build Quality and Serviceability
At this size and price, you want a range that will last a decade or more. Look for heavy-duty cast iron grates (they hold heat and resist warping), a stainless steel body that resists corrosion (ideally 304-grade), and triple-layer oven glass for heat insulation. Pay attention to the knobs — plastic or thin metal knobs that sit close to the oven vent can warp over time. Also check whether the manufacturer provides clear propane conversion instructions and spare parts without a fight.

In‑Depth Reviews
1. AAOBOSI 48 Inch Gas Range with 7.8 Cu. Ft. Double Ovens
The total-BTU king that combines an enormous oven capacity with a griddle for under.
You get the biggest ovens and the most burner power in one package here — and it costs less than any other range in this lineup. The AAOBOSI delivers 93,000 BTU total across seven sealed burners plus an iron center griddle burner. That breaks down to five 12,000 BTU burners, one 15,000 BTU burner, and one 18,000 BTU burner, so you have real high heat for wok cooking or boiling pasta fast. The two separate oven cavities measure 2.8 cubic feet and 5 cubic feet, giving you a combined 7.8 cubic feet of cooking space — noticeably larger than the BRAMA’s 5.5 cubic feet and the Cosmo GRP’s 6.6 cubic feet. Every burner runs on an Italian-designed sealed system with automatic flame-failure shut-off (the gas cuts if a flame blows out). Owners consistently mention how the “oven door seals shut and no heat escapes,” which speaks to the triple-insulated glass construction. The stainless steel body is CSA certified, and the unit comes with a gas converter so you can switch between natural gas and propane right from the start. At 36.25 inches tall and 27.47 inches deep, it sits between standard counter depths, though the backsplash is slightly raised (0.69 inches) as a fire-prevention detail. The rear high-speed cooling system protects the internal electronics and extends the range’s service life.
Every single owner review so far lands at 5 stars, which is unusual for a newly launched product in this category. The consensus is that the cooking power and clean stainless finish are exactly what a home chef needs. Both the heavy-duty cast iron grates and the interior enamel coating clean up with minimal effort — the grates are even dishwasher safe. The dual convection ovens (each with its own fan and temperature probe) let you bake a cake in one cavity while roasting vegetables in the other, and the seven rack positions inside give you flexibility for everything from a tall turkey to shallow sheet trays. The only real note for buyers is that this is a freestanding range, not a slide-in, so it needs a finished backsplash behind it — check your kitchen layout before pulling the trigger.
What wins people over
- 93,000 total BTU across 7 burners plus a griddle — the highest heat output in this comparison.
- 7.8 cu. ft. total oven capacity (2.8 + 5.0) beats every other range here by a measurable margin.
- Italian sealed burners with flame-failure shut-off and included LP/NG converter for low-maintenance setup.
- Dishwasher-safe cast iron grates and easy-clean enamel oven interior.
The honest trade-offs
- Small initial owner pool (11 ratings) so long-term data is still emerging.
- Freestanding design requires a backsplash — not ideal for those with unfinished walls.
Your best pick if: you want the largest oven capacity and maximum burner flexibility at a mid-range price point — this is the highest-scoring range in the group for raw cooking power and value.
Think twice if: you need a slide-in range to sit flush with surrounding countertops, or you want a brand with decades of parts availability.
2. BRAMA 48 Inch Gas Range with 8 Burner Cooktop and Double Oven
Eight burners, continuous grates, and dual-ring flexibility — but the propane-conversion stories are real.
The BRAMA throws raw burner count at your cooking. It packs eight sealed burners onto a single continuous grate surface, including two triple-crown 20,000 BTU burners for serious searing, alongside two rapid burners at 12,000 BTU, two semi-rapid burners at 9,000 BTU, and two auxiliary burners at 6,000 BTU for gentle simmering. That adds up to a theoretical 94,000 total BTU, just edging past the AAOBOSI above. The dual convection ovens split into a 3.5 cubic foot main cavity and a 2 cubic foot secondary cavity, both lined with blue porcelain that reflects heat evenly and cleans up easily. The front right burner features a dual-ring design, meaning you can run the full high-output ring or switch to just the inner ring for warming without burning your sauce. The polished stainless steel body and blue-illuminated knobs give it a professional-kitchen look that owners consistently call “stunning” and “beautiful.” At 48 inches wide and 28.75 inches deep, it sits as a freestanding unit.
The honest reality check here is the propane-conversion experience. Multiple buyers report paying hundreds of dollars for the conversion kit and labor, only to have the range still not operate correctly on LP gas. One owner sums it up directly: “Would love this stove, but for the fact I’ve spent to have it converted to propane, ordered kit from Brama itself and the plumber can still not get it working correctly.” Another unit arrived badly damaged during shipping, though Amazon handled the refund quickly. On the positive side, owners who got a working unit love the analog knob control, the blue lights, and the broil function. The oven knob does get hot when the broiler is running, and the side panels can warm up noticeably, so you need clearance from cabinetry and countertops. This range is a strong value at its price point — but the conversion risk means it is best for homes already plumbed for natural gas, or for buyers willing to work through the LP teething issues with BRAMA’s support team.
Best for natural gas kitchens: if you are on NG, the eight-burner layout with two 20K BTU triple-crown burners gives you restaurant-grade firepower on a continuous grate that pans slide across easily.
The conversion catch: the propane conversion process has frustrated multiple owners — budget extra time and money if you are on LP, and expect to work directly with BRAMA support to dial it in.
Reach for this if: you want the most burner positions available (8) and two dedicated high-output triple-crown burners, and your kitchen already runs on natural gas.
Look elsewhere if: you need propane — the conversion headaches documented by owners make this a gamble no one should take lightly.
3. Cosmo COS-GRP486G 48 Inch Gas Range with 8 Burners and Griddle
Italian-made burners, a backlit LED panel, and corrosion-proof 304 stainless steel for the design-conscious cook.
This Cosmo range from the Vista Collection is built around eight sealed Italian burners, including two 20,000 BTU burners for high-heat work, two 12,000 BTU burners, two 9,000 BTU burners, and two 6,000 BTU simmer burners. It also includes a center griddle attachment so you can do pancakes or smash burgers on the flat top. The total burner output reaches 94,000 BTU — lower than the AAOBOSI and BRAMA, but the burner quality and simmer control are what owners rave about. The rapid convection main oven measures 4.3 cubic feet with a 22,000 BTU bake burner and a 10,000 BTU broil burner, while the secondary oven offers a 14,000 BTU bake burner. That brings the total to 6.6 cubic feet of oven space. The construction is a highlight here: the body is 304-grade stainless steel, which resists corrosion and fingerprints better than standard stainless. The LED light panel running across the front illuminates the knobs and doubles as a subtle nightlight — a design detail buyers consistently call “beautiful.” The heavy-duty cast iron grates cover the entire cooktop in a continuous pattern, so you can slide a pot from one burner to another without lifting.
Looking at owner feedback, functionality and performance are the most-discussed strengths — buyers find the temperature accurate, the broiler effective, and the value strong compared to name-brand ranges costing double. Several owners replaced Viking or Dynasty units with this Cosmo and reported being equally happy with the cooking results. The main durability concern is that a few owners mention issues after four years of use, including a timer dial that spins freely and an igniter that eventually fails. Cosmo does not offer a warranty beyond standard coverage, so servicing a broken part after a few years requires a local appliance repair shop. The LP conversion process is straightforward (you need a small 1.8mm by 60mm flat screwdriver for the adjustment), though very few reviews mention propane performance. With 38 ratings and a solid 4.1-star average, this is the most-reviewed unit in the lineup and has the broadest owner base to draw from.
Why it wins fans: the 304-grade stainless steel body resists rust and smudges far better than standard stainless, and the LED light panel gives your kitchen a modern professional look without an upcharge.
The long-term watch: a small but real number of customers note timer and igniter issues after 4 years, and Cosmo’s warranty does not cover these — factor that into your decision if you want a low-maintenance range for the next decade.
Perfect for the style-focused buyer: if the look of your kitchen matters as much as the cooking, the illuminated LED panel and corrosion-resistant build are unique at this price tier.
skip it if: you plan to keep this range for 10+ years without any tinkering — the post-warranty reliability data is mixed enough to give some buyers pause.
4. Cosmo COS-EPGR486G 48 Inch Gas Range with 6 Burners and Griddle
The Haven Collection’s most spacious double oven with blue LED knob indicators and a 1,700+ owner consensus.
This Cosmo range from the Haven Collection leans into a different layout than the others: it gives you six sealed burners (an 18,000 BTU burner and five 12,000 BTU burners) plus a 15,000 BTU griddle instead of eight or seven separate positions. The total burner output is 78,000 BTU across the cooktop — significantly lower than the AAOBOSI and BRAMA, but you get a larger main oven as a trade-off. The primary oven measures 4.8 cubic feet with both a 22,000 BTU bake burner and a 14,000 BTU broil burner, and the secondary oven adds another 14,000 BTU bake burner, bringing total oven capacity to 7 cubic feet. That makes the main cavity the largest single oven in this comparison, perfect for big holiday roasts or multiple sheet pans. The slide-in form factor is unique here: unlike the freestanding units above, this Cosmo is designed to sit flush with your countertops for a built-in look, with the controls and knobs positioned on the front face rather than a raised backsplash. The bright blue LED lights above each knob add a professional touch that owners consistently call “amazing” and “high-end.” The unit features a cavity cooling ventilation system, overheating protection, and triple-thick oven glass with a cool-to-touch handle for safety.
This is by far the most-reviewed range in the group with 173 ratings, so the owner feedback is deep. The things buyers praise most are quality (30 mentions) and appearance (25 mentions) — the stainless steel body, mirror-finished knobs, and blue lights are a strong visual statement. The size is another standout: many owners replaced a standard 30-inch range and found this Cosmo fit perfectly into their existing cabinetry. The main durability concern is that functionality gets mixed reviews, with 14 owners specifically flagging durability issues. A few reviewers point out that plastic knobs can warp from the heat escaping the oven door gap over time, and replacement knobs cost around from customer service. The griddle performance also draws some criticism for uneven heating. On the positive side, the range ships well-packaged and installation is straightforward for a gas appliance. The total weight of 323 pounds is manageable compared to the BRAMA’s 396 pounds, and the storage drawer at the bottom adds practical space for baking sheets.
The big oven advantage: at 4.8 cubic feet, the main oven cavity is the largest single oven across all four picks — you can fit a 25-pound turkey plus two side dishes comfortably.
The knob durability watch: heat from the oven door gap can warp the plastic knobs over time, and replacements require a call to Cosmo’s support line — plan for this if you use the oven heavily.
Ideal for the slide-in look: if you want a professional, flush-counter finish without a raised backsplash, this is the only option here that delivers that built-in aesthetic.
Think twice if: maximum burner power is your priority — at roughly 78,000 total cooktop BTUs, this range trails the AAOBOSI and BRAMA significantly for high-heat cooking tasks.
Understanding the Specs
Total BTUs — What the big number means
BTU stands for British Thermal Unit, and it measures the heat output of a burner. A higher total BTU number sounds impressive (93,000 in the AAOBOSI vs 78,000 in the Cosmo EPGR), but the real story is how those BTUs are distributed. A range with one 20,000 BTU burner and five weak 6,000 BTU burners is less useful than one with several 12,000 to 15,000 BTU burners spread across the cooktop. Look for at least one high-output burner for boiling and searing (18,000+), plus at least one very low burner (6,000 or less) for delicate simmering.
Oven Capacity and Convection
The total cubic feet number (7.8, 6.7, 6.6, 7.0) combines both ovens. But how those cubic feet are split matters a lot. A 5.0 plus 2.8 split (AAOBOSI) means the main oven can hold a large roasting pan while the smaller one handles sides. A 3.5 plus 2.0 split (BRAMA) means both ovens are on the smaller side for a 48-inch range — fine for everyday cooking but tight for a big Thanksgiving dinner. Convection means a fan circulates hot air around the food, cooking it faster and more evenly than a standard oven. All four ranges here have at least one convection fan.

Final Thoughts: The Verdict
For most buyers, the best 48 inch gas range with double oven winner is the AAOBOSI 48 Inch because it delivers the largest combined oven capacity (7.8 cu. ft.) and the highest total burner output (93,000 BTU) with a griddle, all at a mid-range price point that undercuts the competition. If your kitchen runs on natural gas and you need the maximum number of independent burner positions (8), the BRAMA is the one to reach for. And for the cook who prioritizes a sleek slide-in look and the largest single main oven (4.8 cu. ft.), the Cosmo Haven EPGR is the clear choice — just plan for the possibility of knob replacement down the line.
