The Weber Genesis II S-345 is a premium three-burner propane gas grill exclusive to Costco, combining top-tier performance with durable stainless steel construction. Powered by Weber's GS4 High Performance Grilling System, it delivers exceptionally even heat distribution with minimal flare-ups, making it one of the best gas grills available at any price point.

This grill features three primary burners, a dedicated sear station burner for restaurant-quality sear marks on steaks, and a side table burner for preparing sauces or side dishes simultaneously. The 7mm stainless steel rod cooking grates are easy to clean and retain heat beautifully. Backlit control knobs make nighttime grilling convenient, and the iGrill 3 app-connected thermometer module with four meat probes lets you remotely monitor internal temperatures from your smartphone. A Weber Premium Grill Cover with a three-year warranty is included.

Weber backs every component of this grill with a comprehensive ten-year warranty. The Genesis II S-345 is a Costco-exclusive model not sold directly through Weber's website, representing a significant value over comparable Weber models sold elsewhere. Compatible with liquid propane only.
