With five stainless steel Dual-Tube burners producing 55,000 BTUs, the Imperial QS 590i is designed for strong, even heat across a large grilling surface. The 13,000 BTU side burner expands your prep options for sauces, sides, and pan work, while the 15,000 BTU rear burner and included rotisserie kit add flexibility for more advanced outdoor cooking.
Premium Broil King materials with island-level refinement
This grill center pairs premium cast stainless steel cooking grids, a stainless steel Flav-R-Wave cooking system, and utility cabinetry with a granite countertop to create a more upscale outdoor kitchen presentation. The LP version includes an iQue tank holder, while the NG configuration uses utility drawers within the same polished island footprint.
Integrated island design for a more complete outdoor kitchen setup
The Imperial QS 590i is designed as a finished grill center rather than a simple freestanding grill, making it a strong fit for buyers building a more complete outdoor cooking setup. Its side burner, utility storage, exact-fit island form, and granite workspace all support a more functional and more luxurious entertaining environment.
The Imperial QS 590i combines premium island styling, smart grilling control, and strong burner performance in a format built for serious outdoor entertaining. Its granite countertop and stainless steel cabinetry help create a more polished and more complete backyard kitchen feel.
