Cosmo Appliances Releases 48-Inch Double Oven Gas Range With 8 Burners

The Lumin Collection model COS-GRC488KB pairs a 7.4-cubic-foot capacity with convection in both ovens

CHINO, California – June 15, 2026 – Cosmo Appliances today released the COS-GRC488KB, a 48-inch stainless steel double oven gas range with eight sealed burners, as part of its Lumin Collection. The range is available Home Depot, Lowe’s, Wayfair and Walmart at a list price of $5,399.00.

The range has 7.4 cubic feet of total oven capacity, split between a 4.8-cubic-foot main oven and a 2.6-cubic-foot secondary oven. Each oven has a convection fan to distribute heat more evenly.

The cooktop has eight sealed gas burners on cast iron grates: one 22,000 BTU burner, two at 18,000 BTU, three at 12,000 BTU and two at 9,500 BTU. Together they total 113,000 BTU. The main oven has a 22,000 BTU bake burner and a 13,500 BTU broil burner. The secondary oven has a 14,000 BTU bake burner.

Digital displays with a timer control both ovens. The range is configured for natural gas and can be converted to liquid propane [conversion kit sold separately].

“Households that cook for larger groups need more oven capacity and more burners without giving up control,” said Michael, Brand Manager at Cosmo Appliances. “The 48-inch format lets a kitchen run two ovens at different temperatures while keeping eight burners available for the cooktop.”

The COS-GRC488KB is part of Cosmo’s range lineup, which includes gas, electric and dual fuel models in 30”, 36” and 48” inch widths. Specifications, installation requirements and documentation are available at cosmoappliances.com.
