Broil King Imperial S 590iJ – Premium Outdoor Kitchen Grill Island
Five Dual-Tube burners, a rear rotisserie setup, and a powder-coat finished 304 stainless steel island — everything you need to anchor a premium outdoor kitchen, no connected system required.
The Imperial S 590iJ puts serious cooking capability into a finished outdoor kitchen island without adding a connected monitoring layer between you and the food. Five stainless steel Dual-Tube burners deliver 55,000 BTU across 625 sq. in. of primary cooking space — enough to handle weeknight dinners and full weekend entertaining — and the 875 sq. in. total with the warming rack gives you plenty of room to run a proper spread. The 15,000 BTU rear rotisserie burner and included premium rotisserie kit take weekend cooks well beyond standard grilling, and the 10,000 BTU side burner keeps sauces and sides running alongside. Linear-Flow valves with 180° precision control and a roll-action lid put heat management exactly where it should be: in your hands. Four storage drawers, a side burner cabinet, built-in lights, and illuminated knobs in a powder-coat finished cabinet complete the picture.

Deep Dive — Imperial S 590iJ›
Strong everyday grilling performance for patios and entertaining spaces
The Imperial S 590iJ is built for buyers who want real cooking power without overcomplicating the setup. With five stainless steel Dual-Tube burners, a generous primary cooking area, and professional cast stainless steel grids, it has the performance to handle both quick weeknight meals and more ambitious weekend entertaining. If you want one outdoor kitchen centerpiece that feels capable, durable, and easy to use, this layout makes a real difference.
Premium cooking components with side burner and rotisserie flexibility
This grill island does more than cover the basics. The rear rotisserie burner and included premium rotisserie kit expand what you can cook beyond standard grilling, while the range side burner helps with sauces, sides, and finishing work outdoors. Combined with the stainless steel Flav-R-Wave cooking system and precision heat control, the S 590iJ is built for buyers who want a more substantial grilling experience.
Built-in storage, polished styling, and nighttime cooking convenience
The S 590iJ is more than a grill set into a cabinet. It is a full grill island setup with 304 stainless steel utility drawers, dedicated storage, a side burner cabinet, and details that make evening cooking easier, including built-in 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.
Who It's For — The Deck & Den Take›
The Imperial S 590iJ is for homeowners who grill well, want a finished outdoor kitchen island, and see a connected control system as complexity rather than value. The build is premium throughout — 304 stainless steel, cast stainless steel grids, Linear-Flow valve control — and the included rotisserie kit means you're ready for serious weekend cooks from day one without sourcing anything separately.
If preset Smoke/Roast/Grill modes and electronic meat probes would genuinely change how you cook, the Imperial QS 590iJ adds the iQue connected system on the same five-burner layout. The S 590iJ delivers the same cooking performance without it — typically the right call for cooks who are confident managing heat directly and don't want to pay for features they won't use.
One thing to resolve before ordering: this listing specifies the granite countertop as not included, but does not address the sink or faucet. Confirm with our team whether those need to be sourced separately before you plan your installation — it's easier to have that answer before the island ships than after.
- Homeowners who want a premium finished island and cook confidently without connected monitoring
- Buyers who want strong five-burner performance, a rotisserie setup, and built-in storage in one complete package
- Anyone who values 304 stainless steel construction, a powder-coat cabinet finish, and cooking performance over smart features
- Outdoor kitchen shoppers looking for a solid premium option at a step below the iQue-equipped QS 590iJ
- Cooks who want a rear rotisserie burner and kit included without any additional purchase

Frequently Asked Questions›
Does the Broil King Imperial S 590iJ run on propane or natural gas?›
The Imperial S 590iJ is available in both natural gas and liquid propane configurations. Confirm your fuel preference at the time of purchase.
What is the total BTU output of the S 590iJ?›
The main burners produce 55,000 BTU total. The rear rotisserie burner adds 15,000 BTU and the side burner adds 10,000 BTU, for a combined output of 80,000 BTU across all cooking zones.
What is the total cooking surface area?›
The primary cooking surface is 625 sq. in. With the stainless steel warming rack included, total cooking space reaches 875 sq. in.
Does the Imperial S 590iJ have a smart control system or connected temperature monitoring?›
No. The Imperial S 590iJ uses Linear-Flow valves with 180° precision control and a premium thermometer for temperature management, but does not include a connected smart control system, preset cooking modes, or electronic meat probes. If you want those features, the Imperial QS 590iJ includes the iQue burner monitoring system, preset Smoke/Roast/Grill modes, and two electronic meat probes.
Is the rotisserie kit included, or is it sold separately?›
The premium rotisserie kit is included with the S 590iJ. The 15,000 BTU stainless steel rear rotisserie burner is also built in, so you can use it right out of the box without any additional purchase.
Are electronic meat probes included?›
No. The Imperial S 590iJ does not include electronic meat probes. It comes with a premium thermometer for monitoring cookbox temperature. If meat probes matter to your decision, the Imperial QS 590iJ includes two electronic meat probes as part of its iQue control system.
What stainless steel grade is used for the cabinet and cookbox?›
The cabinet system, cookbox, and Flav-R-Wave cooking system are all 304-grade stainless steel. The cookbox features cast aluminum end caps and a roll-action lid. The cooking grids are professional cast stainless steel. The cabinet and base use a premium powder-coat paint finish.
What storage does the S 590iJ include?›
The island includes four storage drawers in the main five-burner cabinet, a side burner cabinet with tank storage, and a one-door/one-drawer storage cabinet. All are part of the 304 stainless steel cabinet system.
Does the countertop, sink, and faucet come with the island?›
The granite countertop is not included. This listing does not specify whether a stainless steel sink and faucet are included or sold separately — confirm with our team before ordering so you can plan your installation correctly.
Does the S 590iJ have built-in lighting for nighttime grilling?›
Yes. The island includes built-in lights in the cookbox and illuminated control knobs, making it easier to monitor food and adjust settings after dark.
What does the Flav-R-Wave cooking system do?›
The 304 stainless steel Flav-R-Wave system sits between the burners and the cooking grids, acting as a flame tamer that distributes heat evenly and vaporizes drippings to add flavor back into the food.
How does the S 590iJ compare to the QS 590iJ?›
Both models share the same five-burner layout, 55,000 BTU main output, 625 sq. in. primary cooking surface, 875 sq. in. total cooking space, rear rotisserie burner and kit, and 304 stainless steel construction. The key difference is the control system: the QS 590iJ includes iQue burner temperature monitoring with preset Smoke, Roast, and Grill modes and two electronic meat probes. The S 590iJ uses Linear-Flow valve control and a premium thermometer without connected monitoring or probes. If guided control and meat probe monitoring matter, the QS is worth the step up. If you prefer managing the grill directly, the S delivers the same cooking performance without the connected layer.
How does the S 590iJ compare to the S 590iF, S 590iG, and S 590iH?›
All four are Imperial S single-oven five-burner islands with identical cooking specs — 55,000 BTU, 625 sq. in. primary, 875 sq. in. total, 304 stainless steel construction, and powder-coat cabinet finish. The suffix differences (iF, iG, iH, iJ) typically indicate fuel configuration or regional variants. Confirm the specific distinction with our team or the Broil King spec sheets before ordering.
What is the Broil King Imperial S 590iJ warranty?›
Covered by Broil King's limited manufacturer warranty: limited lifetime coverage on stainless steel/porcelain steel lid components and the stainless steel cookbox; 15 years on cast stainless/stainless steel grids, Dual-Tube burners, side burner, rear burner, stainless steel Flav-R-Wave, stainless steel components, and remaining parts and paint warranty, honored directly by the manufacturer. Contact Broil King for warranty service and claims.
