Smart Island Grilling, Complete Storage, 875 Square Inches — All in One Package.
Five Dual-Tube burners, iQue connected temperature control, a rear rotisserie burner with kit included, a 10,000 BTU side burner, and 304 stainless steel cabinetry — the outdoor kitchen that replaces the planning headache with one complete setup.
The Broil King Imperial QS 590iJ is for homeowners who want a finished outdoor kitchen without the project. Five stainless steel Dual-Tube burners deliver 55,000 BTUs across 625 sq. in. of primary cooking surface — enough room for serious family entertaining — and the stainless steel warming rack pushes total capacity to 875 sq. in. The main cookbox runs on Broil King's iQue system: Smoke, Roast, and Grill preset modes dial in temperature management, and two included electronic meat probes keep you monitoring internal temps without the guesswork. The 15,000 BTU rear rotisserie burner and premium kit are already in the box, so rotisserie cooking is available from day one — no separate purchase. A 10,000 BTU range side burner handles sauces, sides, and anything that needs a separate burner. Five-burner 304 stainless steel cabinetry with four storage drawers, a side burner cabinet with tank storage, and a one-door/one-drawer cabinet round out a setup that arrives looking like a finished outdoor kitchen, not a grill waiting to be surrounded by one.

Deep Dive — Imperial QS 590iJ Features
►
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 590iJ 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.
Built-in storage, side burner convenience, and polished island styling
The QS 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 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.

Who It's For — The Deck & Den Take
►
The 590iJ is the smart island for buyers who want the full iQue experience and a complete outdoor kitchen setup without needing the dual-oven layout of the 690iJ. If you don't regularly need to run two separate cooking environments at the same time — or if your patio space or budget doesn't justify the larger 690iJ footprint — this is the model that makes more sense. You get identical iQue control, the same rotisserie kit, the same side burner, and the same cabinet quality. What changes is one cookbox instead of two, and 625 sq. in. of primary space instead of 750 sq. in. For most households, that's still more than enough.
The iQue preset modes — Smoke, Roast, Grill — are genuinely useful if you're new to managing a larger island grill or cooking techniques beyond standard direct grilling. The two included meat probes mean you have temperature visibility on two cuts simultaneously without buying anything extra. That's a meaningful practical advantage over islands that sell probes as accessories.
Who might want to look elsewhere: if you regularly entertain very large groups and want to cook two different proteins at significantly different temperatures simultaneously, the 690iJ's dual-oven layout is worth the step-up. If your outdoor space is truly compact, the Imperial S 520i or Regal S 520i island options offer smaller footprints. And as with the 690iJ: granite countertop is sold separately — plan for that cost in your outdoor kitchen budget.
Practical note: this island is a substantial freight shipment. Confirm your delivery access before ordering and have at least two people available for unloading and positioning.
- Homeowners who want a complete, smart outdoor kitchen island without the dual-oven complexity of the 690iJ
- Buyers who want iQue connected temperature control and guided preset cooking modes in a five-burner setup
- Anyone who cooks for family groups or regular gatherings and wants 875 sq. in. of total cooking capacity
- Cooks who want rotisserie capability and a side burner already included — no add-ons needed
- Buyers choosing between the 590iJ and 690iJ who don't need two independent ovens and want a slightly smaller footprint
- Natural gas or propane setups equally — both fuel versions available

Frequently Asked Questions
►
What is the total BTU output of the Imperial QS 590iJ?►
The main burner output is 55,000 BTU across five stainless steel Dual-Tube burners. The rear rotisserie burner adds 15,000 BTU and the range side burner adds 10,000 BTU, for a combined system output of 80,000 BTU when all burners are running.
What is the cooking area on the Imperial QS 590iJ?►
The Imperial QS 590iJ offers 625 sq. in. of primary cooking surface. Including the stainless steel warming rack, total cooking space is 875 sq. in.
Does the Imperial QS 590iJ have two independent ovens like the 690iJ?►
No. The Imperial QS 590iJ has a single cookbox. The dual independent oven layout is a feature of the 690iJ models. The 590iJ offers the same iQue smart control system, rotisserie, side burner, and cabinetry — with one cookbox and 625 sq. in. of primary cooking surface instead of the 690iJ's two separate cooking environments.
What is the iQue system and what does it do?►
iQue is Broil King's connected burner control and temperature monitoring system on the main cookbox. It includes preset cooking modes — Smoke, Roast, and Grill — that guide temperature management for different cooking styles. Two electronic meat probes are included to monitor internal food temperatures. Broil King lists Wi-Fi and Bluetooth connectivity through the Broil King Grilling App.
Is a rotisserie kit included with the Imperial QS 590iJ?►
Yes. The Imperial QS 590iJ includes both a 15,000 BTU rear rotisserie burner and a premium rotisserie kit in the box — no additional accessory purchase required for rotisserie cooking.
Is the granite countertop included?►
No. The granite countertop is not included and is sold separately. The island ships with all cabinetry, the grill, all burners, and the included accessories listed above — but the countertop finish requires a separate purchase.
What fuel options are available for the Imperial QS 590iJ?►
The Imperial QS 590iJ is available in both natural gas (NG) and liquid propane (LP). Select the correct fuel version for your outdoor kitchen connection at the time of purchase — the two versions are separate SKUs and are not interchangeable without a conversion kit.
What are the assembled dimensions of the Imperial QS 590iJ?►
The assembled island measures approximately 49.12" H × 110.7" W × 30.9" D. Listed weight is 926 lbs. for model 696844J; confirm freight documentation if fuel-specific shipping weights are required.
What cabinet storage is included with the 590iJ island?►
The island includes a five-burner 304 stainless steel cabinet with four storage drawers under the main grill, a side burner cabinet with tank storage for a propane tank (LP version), and a one-door / one-drawer storage cabinet. All cabinetry has a premium powder-coat paint finish on the cabinet and base.
What warranty covers the Imperial QS 590iJ?►
The Imperial QS 590iJ is covered by Broil King's manufacturer warranty, honored directly by Broil King. Broil King provides limited lifetime coverage on stainless steel/porcelain steel lid components and the stainless steel cookbox, plus 15 years on cast stainless/stainless steel grids, Dual-Tube burners, the side and rear burners, stainless steel Flav-R-Wave, stainless steel components, and remaining parts and paint. The warranty does not state a separate iQue/electronics term; labor, service calls, shipping, removal, and reinstallation are excluded. Warranty applies only to products purchased and used in the country of purchase.
How does the Imperial QS 590iJ compare to the Imperial QS 690iJ?►
The primary differences are the cookbox layout and cooking surface. The 690iJ has two independent cookboxes (500 sq. in. + 250 sq. in.) and six main burners at 60,000 BTU; the 590iJ has one cookbox at 625 sq. in. and five main burners at 55,000 BTU. Both include identical iQue smart control, the same rotisserie burner and kit, the same side burner, and equivalent 304 stainless steel cabinetry. The 590iJ is the right choice when you don't need simultaneous dual-temperature cooking environments — you get the same smart island experience at a more accessible price point and slightly smaller footprint.
Does this island require professional installation?►
The island arrives largely pre-assembled and requires final setup rather than full construction. Natural gas connections must be made by a licensed gas professional. LP propane setup should follow the instructions in the owner's manual. Due to the size and weight of this island, plan for at least two people for unloading and positioning. An Assembly Manual is linked in the Manuals & Documents section above.
