Five Burners, Infrared Searing, and 875 Square Inches of Total Cooking Space — the Regal S 590 Pro IR Is Built for Cooks Who Mean Business

The Regal S 590 Pro Infrared brings 55,000 BTUs of Dual-Tube burner power, a 10,000 BTU infrared side burner, 875 sq. in. of total cooking space, and an included rotisserie kit to a polished enclosed-cabinet freestanding grill.

Five stainless steel Dual-Tube burners give you 55,000 BTUs of even, controlled heat across 625 square inches of primary cooking surface — enough room to run multiple cooking zones at once without crowding. The 10,000 BTU infrared side burner closes the gap between a backyard grill and a proper sear station, and the 15,000 BTU rear rotisserie burner with included kit means whole birds and weekend roasts are covered the day the grill arrives. The stainless steel warming rack brings total capacity to 875 sq. in., 9 mm stainless steel cooking grids hold heat better than standard grates, and the Flav-R-Wave cooking system puts drippings-smoke back into your food. Illuminated control knobs and built-in lights keep things running after dark, and the enclosed cabinet base makes the whole setup look as purposeful as it performs — all without the complexity or cost of a built-in outdoor kitchen installation.

Why the Regal S 590 Pro Infrared Stands Apart

Five things that put this grill ahead of a standard five-burner freestanding setup.

55,000 BTU

5-Burner Main Output

Five stainless steel Dual-Tube burners deliver even, high-output heat across 625 sq. in. of primary cooking space — enough to run multiple cooking zones simultaneously without crowding.

10,000 BTU

Infrared Side Burner

Infrared technology converts gas heat into intense surface energy, reaching temperatures high enough for a genuine steakhouse-style sear — with faster preheat than a conventional burner.

875 sq. in.

Total Cooking Space

625 sq. in. of primary cooking surface plus a stainless steel warming rack brings total usable capacity to 875 sq. in. — room for a full entertaining spread.

9 mm

Stainless Cooking Grids

Thick 9 mm stainless steel retains heat longer and produces better sear marks than standard grates — with none of the seasoning or rust concerns of cast iron.

15,000 BTU

Rear Rotisserie + Kit Included

A dedicated rear rotisserie burner and included rotisserie kit mean whole birds and roasts are on the menu from day one — no separate purchase required.

Five-burner power with infrared and rotisserie versatility

With five stainless steel Dual-Tube burners producing 55,000 BTUs, the Regal S 590 Pro Infrared is designed for strong, even heat across a larger main grilling surface. The 10,000 BTU infrared side burner expands your options for high-heat searing and side-burner prep work, while the 15,000 BTU rear rotisserie burner helps support poultry, roasts, and more elevated outdoor menus.

Premium stainless steel grilling surfaces and flavor performance

The 9 mm stainless steel cooking grids provide durable heat retention with a more premium feel than standard grates, while the stainless steel Flav-R-Wave system helps vaporize drippings and return richer barbecue flavor to the food. Combined with the stainless steel warming rack and side shelves, this grill is designed to deliver a more substantial and more refined cooking experience for buyers who want more than a basic freestanding model.

Refined freestanding design with polished cabinet styling

Stainless steel side shelves, illuminated control knobs, and an enclosed cabinet base give the Regal S 590 Pro IR a cleaner, more finished appearance while preserving the flexibility of a freestanding layout. For homeowners building a more complete outdoor cooking setup, it offers a compelling balance of premium materials, practical storage, and grilling versatility.

Built-in convenience for day-to-night outdoor cooking

The included rotisserie kit and built-in lights add practical convenience right out of the box, helping this grill transition smoothly from casual weeknight meals to larger evening cookouts. Its combination of stronger burner output, premium stainless steel construction, and user-friendly features makes it especially attractive for buyers who want a more advanced backyard grill without stepping into a full island installation.

Who It's For — The Deck & Den Take

►

The Regal S 590 Pro IR is the five-burner for someone who wants a genuinely capable grill without paying for smart features they won't use. It has everything the Regal Q 590 Pro IR has — five Dual-Tube burners, infrared side burner, rear rotisserie burner and kit, 9 mm cooking grids, enclosed cabinet base — minus the iQue Wi-Fi and Bluetooth connectivity. If you don't need to monitor your grill from your phone, you don't need to pay for it.

The 875 square inches of total cooking space is worth paying attention to. The 625 sq. in. primary surface gives you five burners of usable grill space, and the warming rack adds 250 more square inches for holding finished food, warming buns, or keeping sides at temperature while the main course finishes. That's a meaningful amount of capacity for a household that entertains regularly.

Who should look at something else: if smart connectivity matters to you, step up to the Regal Q 590 Pro IR — same grill, adds iQue. If you consistently cook for ten or more people, the Regal S 690 Pro IR's dual-oven layout and 750 sq. in. primary surface may be a better fit. And if you're planning to eventually build an outdoor kitchen, starting with a built-in grill head instead of a cart grill is worth considering.

  • Homeowners who want premium five-burner freestanding performance without smart connectivity costs
  • Buyers who entertain regularly and want 875 sq. in. of total cooking capacity in a freestanding layout
  • Cooks who want an infrared side burner for genuine searing alongside the main grill
  • Anyone who wants a dedicated rear rotisserie burner and kit included from day one
  • Buyers who prefer a non-app grill experience but still want premium construction and feature depth

Frequently Asked Questions

►
Does the Regal S 590 Pro Infrared come in both propane and natural gas?►

Yes. The Regal S 590 Pro Infrared is available in both Liquid Propane (LP, model 958944) and Natural Gas (NG, model 958947). Select your fuel type at checkout.

What is the primary vs. total cooking space?►

The primary cooking surface is 625 sq. in. The stainless steel warming rack adds additional capacity, bringing total cooking space to 875 sq. in.

What is the total BTU output?►

The five main Dual-Tube burners produce 55,000 BTU. The infrared side burner adds 10,000 BTU, and the rear rotisserie burner adds 15,000 BTU.

Is the rotisserie kit included?►

Yes. The rotisserie kit is included, along with the 15,000 BTU rear rotisserie burner. No separate purchase is required.

What makes the infrared side burner different from a standard side burner?►

An infrared side burner focuses the gas flame onto a ceramic tile surface to convert heat into infrared energy, achieving significantly higher surface temperatures than a conventional burner. This makes it better suited for high-heat searing, wok cooking, and tasks that require intense, direct heat quickly.

Does the Regal S 590 Pro Infrared have smart Wi-Fi or Bluetooth connectivity?►

No. The Regal S 590 Pro Infrared does not include iQue smart technology. If Wi-Fi and Bluetooth connectivity are important to you, the Regal Q 590 Pro Infrared includes iQue and is otherwise very similar in configuration.

What type of cooking grids does this grill use?►

The grill comes with 9 mm stainless steel cooking grids. Thicker than standard grill grates, they provide better heat retention, more durable searing surfaces, and require far less maintenance than cast iron.

What is the Flav-R-Wave cooking system?►

The Flav-R-Wave cooking system uses stainless steel wave-shaped components positioned between the burners and cooking grids. They catch drippings and vaporize them, circulating smoke and flavor back up to the food for a richer barbecue result.

What are the assembled dimensions and weight?►

The assembled dimensions are 62.5" W x 24.8" D x 49.2" H. Weight is 215 lbs. for the LP version and 219 lbs. for the NG version.

What warranty does the Regal S 590 Pro Infrared carry?►

Covered by Broil King's Lifetime warranty on the cookbox, with 15-year top-to-bottom coverage, honored directly by Broil King (Onward Manufacturing Company).

How does the Regal S 590 Pro IR compare to the Regal Q 590 Pro IR?►

Both are five-burner freestanding grills with a 10,000 BTU infrared side burner, 15,000 BTU rear rotisserie burner, 9 mm stainless steel cooking grids, and an enclosed cabinet base. The key difference is connectivity: the Regal Q 590 Pro IR includes iQue smart technology (Wi-Fi and Bluetooth) while the Regal S 590 Pro IR does not. The S series also specifies primary cooking space (625 sq. in.) and total cooking space (875 sq. in.) separately.

How does the Regal S 590 Pro IR compare to the Regal S 490 Pro IR?►

The 590 adds a fifth burner, raises main BTU output from 50,000 to 55,000, and increases primary cooking space from 500 to 625 sq. in. (total 875 vs. 695 sq. in.). Both share the same infrared side burner, rear rotisserie burner and kit, 9 mm cooking grids, illuminated knobs, built-in lights, and enclosed cabinet base.

Is this grill freestanding or does it require installation?►

The Regal S 590 Pro Infrared is a freestanding grill with an enclosed cabinet base — no outdoor kitchen island or custom enclosure is required. It can be placed anywhere on your patio or deck with appropriate gas line or propane tank access.

    The five main Dual-Tube burners produce 55,000 BTU. The infrared side burner adds 10,000 BTU, and the rear rotisserie burner adds 15,000 BTU.

    Is the rotisserie kit included?►

    Yes. The rotisserie kit is included, along with the 15,000 BTU rear rotisserie burner. No separate purchase is required.

    What makes the infrared side burner different from a standard side burner?►

    An infrared side burner focuses the gas flame onto a ceramic tile surface to convert heat into infrared energy, achieving significantly higher surface temperatures than a conventional burner. This makes it better suited for high-heat searing, wok cooking, and tasks that require intense, direct heat quickly.

    Does the Regal S 590 Pro Infrared have smart Wi-Fi or Bluetooth connectivity?►

    No. The Regal S 590 Pro Infrared does not include iQue smart technology. If Wi-Fi and Bluetooth connectivity are important to you, the Regal Q 590 Pro Infrared includes iQue and is otherwise very similar in configuration.

    What type of cooking grids does this grill use?►

    The grill comes with 9 mm stainless steel cooking grids. Thicker than standard grill grates, they provide better heat retention, more durable searing surfaces, and require far less maintenance than cast iron.

    What is the Flav-R-Wave cooking system?►

    The Flav-R-Wave cooking system uses stainless steel wave-shaped components positioned between the burners and cooking grids. They catch drippings and vaporize them, circulating smoke and flavor back up to the food for a richer barbecue result.

    What are the assembled dimensions and weight?►

    The assembled dimensions are 62.5" W x 24.8" D x 49.2" H. Weight is 215 lbs. for the LP version and 219 lbs. for the NG version.

    Covered by Broil King's Lifetime warranty on the cookbox, with 15-year top-to-bottom coverage, honored directly by Broil King (Onward Manufacturing Company).

    How does the Regal S 590 Pro IR compare to the Regal Q 590 Pro IR?►

    Both are five-burner freestanding grills with a 10,000 BTU infrared side burner, 15,000 BTU rear rotisserie burner, 9 mm stainless steel cooking grids, and an enclosed cabinet base. The key difference is connectivity: the Regal Q 590 Pro IR includes iQue smart technology (Wi-Fi and Bluetooth) while the Regal S 590 Pro IR does not. The S series also specifies primary cooking space (625 sq. in.) and total cooking space (875 sq. in.) separately.

    How does the Regal S 590 Pro IR compare to the Regal S 490 Pro IR?►
