The Broil King Imperial S 590i is the grill center for the buyer who wants the whole picture: five Dual-Tube burners delivering 55,000 BTUs across 625 square inches of primary cooking surface, a 10,000 BTU side burner for prep work, and a 15,000 BTU rear rotisserie burner with the kit already in the box. Broil King's Flav-R-Cast stainless steel cooking grids bring exceptional heat retention and a proper sear to every cook. Built-in oven lights and illuminated control knobs extend the session well into the evening without squinting at settings.

Deep Dive — Imperial S 590i
›
Premium Broil King construction for elevated outdoor kitchen performance
The Imperial S 590i pairs a stainless steel grill body with premium Flav-R-Cast stainless steel cooking grids, a stainless steel Flav-R-Wave cooking system, and utility cabinetry finished with a granite countertop. On the LP model, the cabinet includes a tank holder, while the NG version uses 304 stainless steel utility cabinet drawers, helping this island deliver a more complete built-in feel without sacrificing everyday functionality.
Five-burner power with side burner and rotisserie versatility
With five stainless steel Dual-Tube burners producing 55,000 BTUs, the Imperial S 590i is built for even heat delivery and strong performance across a large primary cooking surface. The side burner expands your prep flexibility for sauces, sides, and pan work, while the built-in rear burner and included rotisserie kit support more advanced roasting and entertaining use cases.
Illuminated controls and interior lighting for premium day-to-night use
The Imperial S 590i includes built-in oven lights and illuminated control knobs to support easier cooking after dark and a more premium user experience overall. These upscale convenience features, combined with the included premium cover and the refined island cabinetry, make it a compelling centerpiece for a more ambitious outdoor cooking setup.
Island-ready design with integrated utility storage
This grill center is part of Broil King's Imperial S island lineup and is positioned in the small 6 to 8 foot island range. Its centered grill placement, integrated utility storage, and side burner make it an attractive fit for buyers who want a more refined outdoor kitchen layout without piecing together multiple separate components.
Who It's For — The Deck & Den Take
›
The Imperial S 590i is for the buyer who wants to arrive — not assemble. Everything is here: five burner zones, a rotisserie, a side burner, a granite countertop, built-in lighting, and a premium cover. You're not buying a grill and then hunting for add-ons. One delivery, one setup, done.
It makes the most sense for homeowners with a dedicated patio space and some room to commit to a 79-inch wide station. If your outdoor space is tighter, the Imperial S 590i's smaller sibling or a Baron Island is worth considering instead. And if you want something even larger — more burners, wider counter run — the 690i steps up from here.
One practical note on fuel: the LP version includes a pull-out tank drawer for propane storage, which is convenient. But if you have a natural gas line at the house, the NG version eliminates tank swaps entirely and is worth the planning effort if your setup allows for it.
- Homeowners who want a complete, premium island station with granite counter and no immediate add-ons required
- Buyers who entertain regularly and need all three cooking zones — primary grill, side burner, and rotisserie
- Shoppers comparing complete outdoor kitchen islands in the 6–8 ft range
- LP or natural gas households — both configurations available (LP: 896844 / NG: 896847)
- Buyers who want oven lights and illuminated knobs for evening entertaining
