Broil King Imperial QS 590iG – Smart Outdoor Kitchen Grill Island
The Broil King Imperial QS 590iG is a premium outdoor kitchen grill island for homeowners who want a polished cooking setup without piecing together separate components. It is built for patios, entertaining spaces, and buyers who want smart grilling control, premium storage, and the look of a finished island in one package. What makes it stand out is the connected iQue temperature control in the main cookbox, the full stainless steel cabinet base, and a feature set that gives you more capability than a standard freestanding grill. You get the grill island cabinet system, five stainless steel burners, cast stainless steel cooking grids, a rear rotisserie burner with premium rotisserie kit, a side burner, oven lights, illuminated knobs, and built-in storage drawers, making it a compelling choice for shoppers exploring premium outdoor kitchen islands that feel complete from day one.
Smart iQue control for easier, more confident grilling
The main cookbox uses Broil King’s iQue burner temperature control and monitoring system, giving you a more guided cooking experience than a traditional gas grill island. Preset smoke, roast, and grill functions help simplify heat management, while the included electronic meat probes add more confidence when you are cooking larger cuts. If you want a premium grill island that feels easier to manage without losing performance, this setup makes a real difference.
Strong burner performance with room for everyday meals and entertaining
With five stainless steel Dual-Tube burners, 625 square inches of primary cooking space, and 875 square inches of total cooking space including the warming rack, the QS 590iG has the size and power to handle both weeknight dinners and larger gatherings. The side burner helps with sauces and sides, while the rear rotisserie burner expands what you can cook beyond standard grilling. Want to know more? Reach out to us.
Built-in storage, side burner convenience, and polished island styling

It is a full grill island setup with 304 stainless steel utility drawers, dedicated storage, a side burner for sauces and sides, and details that make evening cooking easier, including oven lights and illuminated control knobs. It gives outdoor kitchens a more finished, furniture-like feel than a bare built-in grill head alone, while still keeping performance front and center. For shoppers comparing premium backyard cooking setups from leading manufacturers, browsing our outdoor living brands page can help you see where Broil King fits.
