Weber Summit SB38 Built-In Gas Barbecue Stainless Steel (LPG)

If your outdoor area is more than a patio — if it’s where you actually entertain — the Weber Summit SB38 Built-In Gas Barbecue Stainless Steel (LPG) is designed to anchor the whole setup. It’s built to integrate into a proper outdoor kitchen, handle large cook-ups without feeling stretched, and add new cooking techniques that go well beyond standard grilling.

Being LPG gives you flexibility where natural gas isn’t available. Run a refillable cylinder (sold separately), keep a spare ready, and you’ve got a built-in barbecue that’s ready for big weekends and midweek “let’s just cook outside” dinners.

Top-down infrared burner for a restaurant-style finish

This is the feature that turns heads (and plates). The top-down, high-heat infrared burner pushes intense radiant heat down onto the food, helping you achieve edge-to-edge caramelisation and a confident finish.

It’s ideal for putting the final touch on steaks, browning the top of roasts, crisping skin, and adding that extra colour that makes food look as good as it tastes.

Five burners plus a dedicated sear burner for true zone cooking

With five main burners you can create separate heat zones across the cooking surface — sear on one side, roast or cook lid-down in the middle, and keep a gentler area running for sides or holding food. Add the sear burner overhead and you’ve got a setup that makes timing easier when you’re feeding a crowd.

The practical result: less batch cooking, less waiting around, and more food landing together.

Rotisserie and smoker box for bigger flavour variety

The integrated rotisserie is built for crowd-friendly cooks — multiple chickens, rolled pork, beef roasts, and larger cuts that benefit from even browning as they turn. It’s an easy way to serve something impressive without making the cook complicated.

When you want wood-smoked depth, the stainless-steel smoker box adds a low-and-slow flavour boost to chicken, roasts, ribs and more. It’s a simple shift that changes the whole character of the cook.

Two-tier cooking surface for smoother entertaining

A two-tier cooking surface is a quiet weapon for entertaining. Grill mains down low while warming, toasting, or holding food up top. Buns, veg, resting steaks, keeping the first batch hot — it all becomes simpler when you’ve got a second level that’s actually usable.

Weber Summit SB38 Built-In Gas Barbecue Stainless Steel (LPG) and the Weber Crafted system

This model includes Weber Crafted cooking grills and the frame kit, so you can expand your cooking styles over time with compatible accessories (sold separately). That’s how you go from “BBQ night” to pizza nights, wok-style cooks, griddle sessions and more — without replacing your whole barbecue.

(If you’re chasing hot-plate style cooking, the Weber Crafted griddle is commonly bundled separately.)

Night Vision lighting and backlit control dials for after-dark cooking

Late afternoon cook-ups are great until you can’t see what you’re doing. Night Vision LED lighting illuminates the grill surface so you can keep cooking confidently, and the backlit control dials make adjustments easier in low light.

It’s a genuinely practical upgrade — and it makes evening entertaining feel seamless.

Weber Summit SB38 Built-In Gas Barbecue Stainless Steel (LPG) built-in cabinetry and trim kit

A built-in barbecue should look like it belongs there. The under-barbecue cabinetry and trim kit are designed to give a clean, integrated finish in your outdoor kitchen layout, keeping everything tidy and purpose-built.

LPG setup notes

This model is designed for LPG using a refillable cylinder (sold separately). Built-in installations vary, so ensure ventilation, clearances, and cylinder placement follow the supplied installation guidance.
