Imperial S 590i Island Grill

A five-burner built-in island version of Broil King's flagship Imperial line, with a 304 stainless steel cookbox and granite countertop.

$7,999Approx. MSRP

A solid pick for someone who wants a serious mid-size island grill and will do basic maintenance, but not the cheapest way to get into grilling.

Pros

  • Best-value pick in the Imperial line with a strong balance of cooking space, power and price
  • Excellent indirect/roasting performance in independent testing
  • Lifetime cookbox and 10-year burner warranty are strong even if the general parts warranty is shorter
  • Loads of cooking room — 875 sq in feeds a crowd
  • Serious heat (55,000 BTU) — sears fast

Watch-outs

  • Only a 2-year warranty on general parts, weaker than some competitors
  • Long-term owners in wet climates report rust working through the cookbox over many years
  • Island-style footprint takes up more patio space than a cart grill
  • Premium price ($7,999)

Known niggles

  • Some owners report burner rusting within the warranty period, though Broil King replaced them
  • One long-term owner reported internal rust-through requiring welded patches despite regular cover use
  • Occasional flare-ups reported when cooking fatty meats like chicken
