36,000 BTUs of Stainless Power, Sized to Fit Almost Anywhere
Full-size grilling power in a 25-inch footprint, built for the spaces a bigger grill won't fit.
36,000 BTUs across three 304 stainless tube burners puts even, edge-to-edge heat within reach on a condo patio, rooftop deck, or tight outdoor kitchen — no cold corners to chase your food around. 550 sq in of total cooking space, including a 123 sq in warming rack, gives you room to plate a full family meal in one pass. A #443 stainless body and double-lined hood shrug off weather without losing their shine, and piezo plus flash-tube ignition lights instantly with no electrical hookup needed. Available in natural gas or liquid propane, the Sizzler 25 brings Summerset's build quality to a footprint almost any install can handle.

Heat That Stays Where You Put It

Who It's For — The Deck & Den Take›
The Deck & Den Take — The Sizzler 25 is the grill we point space-conscious buyers toward when they still want real BTUs and stainless durability without the footprint of a 30-inch unit. If you're regularly cooking for more than 4-5 people, look at adding the optional infrared sear burner or stepping up to the Sizzler 32 for more primary cooking area — but for a condo patio, rooftop deck, or secondary kitchen island, this size hits the mark.
-
Condo and townhome owners who need full grilling performance on a patio or balcony footprint.
-
Multi-family and rooftop installs where electrical hookups for ignition aren't practical — piezo ignition needs no power.
-
Compact outdoor kitchen builds looking for a built-in grill that fits a smaller island without sacrificing stainless quality.
-
Everyday grillers who want dependable mid-range heat for burgers, chicken, and vegetables rather than a high-end pro rig.
-
Secondary or guest-house kitchens that need a reliable grill without the premium price tag of Summerset's larger lines.
