Deep Dive — Imperial S 590iF›
Strong everyday grilling performance for patios and entertaining spaces
The Imperial S 590iF 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 590iF is built for buyers who want a more substantial grilling experience.
Built-in storage, polished styling, and nighttime cooking convenience
The S 590iF 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 590iF is a strong pick for homeowners who want a premium, finished outdoor kitchen island and cook well enough by feel that they don't need connected temperature monitoring or preset cooking modes. If you know how to manage a grill and you want it to look great, hold up long-term, and have everything — burners, rotisserie, side burner, storage — in one package, this delivers all of that cleanly.
If you want iQue smart control, preset Smoke/Roast/Grill modes, and included electronic meat probes, step up to the Imperial QS 590iF or QS 590iG — those models are built on the same cabinet and cooking spec but add the connected control layer. The Imperial S skips that and keeps the focus on cooking performance and build quality.
The granite countertop, sink, and faucet are sold separately on this model. Plan for those before the island ships — having your countertop dimensions sorted before delivery is the one thing most buyers wish they'd done sooner.
- Homeowners who want a premium finished island and are confident grilling without connected monitoring
- Buyers who want strong five-burner performance, a rotisserie setup, and built-in storage in one complete package
- Anyone who values build quality, 304 stainless steel construction, and a polished finish over smart features
- Outdoor kitchen shoppers looking for a solid premium option at a step below the iQue-equipped QS line
- Cooks who want a rear rotisserie burner and kit included without any additional purchase

Frequently Asked Questions›
Does the Broil King Imperial S 590iF run on propane or natural gas?›
The Imperial S 590iF 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 590iF?›
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 590iF have a smart control system or connected temperature monitoring?›
No. The Imperial S 590iF 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 590iF or QS 590iG includes the iQue burner monitoring system and two electronic meat probes.
Is the rotisserie kit included, or is it sold separately?›
The premium rotisserie kit is included with the S 590iF. 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 590iF does not include electronic meat probes. It comes with a premium thermometer for monitoring cookbox temperature. If meat probes are important to your purchase decision, the Imperial QS 590iF and QS 590iG both include two electronic meat probes as part of their iQue control systems.
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 590iF 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?›
No. The granite countertop, stainless steel sink, and faucet are sold separately. Measure and budget for those items before installation to complete the island look.
Does the S 590iF 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 590iF compare to the QS 590iF or QS 590iG?›
The cooking specs are similar — five burners, 55,000 BTU, 625 sq. in. primary cooking surface, 875 sq. in. total, and 304 stainless steel construction throughout. The key difference is the control system. The QS 590iF and QS 590iG both include iQue burner temperature monitoring, preset Smoke/Roast/Grill modes, and two electronic meat probes. The Imperial S 590iF does not include a connected control system or meat probes — it uses Linear-Flow valve control and a premium thermometer. If smart monitoring and preset modes matter to you, the QS versions are worth the step up. If you prefer straightforward, performance-focused grilling without the connected layer, the S 590iF delivers that cleanly.
What is the Broil King Imperial S 590iF 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.
