Summerset Grill Liner for the 25 inch Sizzler: A heat barrier for wood framed islands

The Summerset Grill Liner for the 25 inch Sizzler is a stainless steel sleeve that lines the cutout for a built in grill. It is for an island framed in wood or any other material that can burn, because the heat from the grill would otherwise reach the framing. Liner means a double walled stainless steel box, one inch thick, that goes into the cutout first, and the grill drops into it. It fits only the 25 inch Sizzler. Each grill size has its own liner. It is built from 304 stainless steel, the grade that holds up best outdoors, and Summerset backs it with a lifetime warranty.

An island built entirely of block, metal studs, and cement board does not need one. Frame the opening to the liner size in the grill manual, not to the grill itself. It suits a small patio island framed in wood, where the framing sits even closer to the firebox. Planning a larger grill? See the Summerset Grill Liner for the 32 inch Sizzler and Sizzler Pro. The Summerset Grill Liner for the 25 inch Sizzler ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ

I am planning a compact patio island – is a liner still necessary?

Size does not change the physics: if the enclosure around your 25-inch Sizzler is wood or composite, it needs the GL-SZR25. Small islands actually put framing closer to the firebox, so the 1-inch insulated barrier is arguably even more important in a tight build.

Does this liner fit any Sizzler, or just the 25?

Just the 25-inch Sizzler – Summerset makes separate liners for the 32- and 40-inch models in the series. The GL-SZR25 matches the smallest grill in the family, which is exactly what makes the fit snug and the finished reveal look clean.

What is the cheapest safe way to build a small grill island?

Wood framing plus a liner is the classic budget route. Lumber is cheaper and easier to work than masonry, and the GL-SZR25 is what makes that construction safe for a bbq grill. Frame it, face it however you like, sleeve the cutout, drop in the Sizzler 25.

What is the GL-SZR25 built from?

Double-walled, weather-resistant #304 stainless steel at 1 inch thick. An interesting detail: that is a higher steel grade than the #443 used on the Sizzler body itself, making the liner one of the most corrosion-proof parts of the whole station.

Does it need any maintenance once installed?

Practically none – an occasional wipe of the visible stainless lip when you clean the Sizzler 25 is all the GL-SZR25 asks. There is nothing mechanical to service, and the steel never needs sealing, painting, or any kind of seasonal attention.

If I later rebuild with brick instead, is the liner wasted?

A true full-masonry island would not require it, so you could omit it there. But if brick ends up as a veneer over wood studs – the most common DIY approach – the GL-SZR25 is still doing essential protective work behind that facade.

How long is it warrantied for?

For life. The GL-SZR25 is covered by Summerset’s Gold Standard Lifetime Warranty, their industry-leading program – the same coverage tier their premium grills carry, on a component designed to be framed permanently into your patio island and never replaced.
