Built-In Grill Cutout Dimensions: Weber, Coyote, Bull, Summerset, Alfresco, Hestan Chart

Why cutout dimensions matter more than brochure reviews

Every contractor who has rebuilt a counter will tell the same story. Island poured, tile set, grill arrives, grill does not fit. The homeowner swears the measurements came from the spec sheet. They did. They came from the wrong spec sheet — a different model year, a different sub-model, or a competitor they read earlier that morning. The built-in gas grill category has no cutout standard. Every brand publishes its own rectangle, and the rectangles are different enough that a counter cut for a Bull Angus will not fit a Coyote C-Series 36, even though both are nominally 30-ish inches wide.

The chart below is the cheat sheet. Every grill we stock from Weber, Coyote, Bull, Summerset, Alfresco, and Hestan — width, depth, height, gas stub position, ventilation requirement. Paired with the per-brand notes further down, it is the reference we wish we’d had on our own first built-in install.

Weber Summit — the widest footprint

The Weber Summit SB38 S wants a cutout of 36 1/2 inches wide by 24 3/8 inches deep by 10 3/4 inches tall. Deeper than every other brand on this list. That extra 4 inches of depth is where the smoker box, the sear burner, and the rotisserie motor housing sit. Rough in a stub-up gas line at center-rear. Weber publishes 10 to 12 inches of clearance to combustible surrounds and zero clearance to non-combustibles (stone, stainless jacket, tile over cement board).

A common mistake on Summit installs is building the counter to the width of the grill head, not the width of the cutout. The flange that sits on top of the counter is 38 inches edge-to-edge, so the counter needs at least 2 inches of material on each side for the flange to land on. Measure the flange, not the hole.

Coyote C, CL, and SL — the predictable 20 1/4 in depth

Coyote’s advantage is that it publishes the same depth across the entire built-in lineup. C-Series, CL-Series, and the sear-forward SL-Series all live inside a 20 1/4 inch depth window. Widths scale with the grill size — 28, 34, or 36 inches of cutout for the 28, 34, and 36-inch heads. Height 10 inches. Gas stub center-rear. Two 10 square inch ventilation openings in the island on opposing sides, within 2 inches of the base.

If an island is getting speced before the exact Coyote model is chosen, specify the cutout to the 36-inch C-Series dimensions and leave the burners decision for later. Any Coyote built-in drops into that opening, and you keep the ability to trade up to the SL-Series without touching stone.

Bull Outlaw, Angus, and Brahma — left-rear gas is the trap

Bull Outlaw, Bull Angus, and Bull Brahma share a 20 3/4 inch depth and a 9 3/4 inch cutout height. Width is where they split — 30 1/2 for Outlaw and Angus, 38 1/4 for Brahma. Gas stub is left-rear, which is where more than one rookie plumber has installed a center-rear stub-up and had to cut and re-route the day before grill delivery. Rough in the gas against the left wall of the cavity.

Bull’s install documentation calls for a non-combustible surround on the Angus and Brahma lines — stone, stucco, cement board with tile, or stainless jacket. The Outlaw tolerates combustible material at 12 inches of lateral clearance. If the island is framed in wood against an exterior wall, either pick the Outlaw or sheath the surround properly.

Alfresco ALXE — the vent-panel brand

Alfresco is the only brand on this chart that ships its own ventilation panels as part of the install kit. The Alfresco ALXE 36 wants a cutout of 35 1/2 inches wide by 22 1/2 inches deep by 11 3/4 inches tall — the deepest 36-inch in the group. That depth is for the pivoting halogen interior lights, the custom rotisserie track, and the double-wall insulated jacket. Gas stub lives right-rear.

The ALXE vent panel is a 15-inch stainless grille that mounts into the island wall below the grill. Factory spec forbids substituting a generic louvered vent — the panel is engineered for the required airflow, and the warranty voids on substitution. Build the island with a panel-ready opening cut to Alfresco’s drawing before the stone goes up.

Summerset Resort, Sizzler, and the single-piece casting

Summerset is the install-friendly brand in this chart. The Resort SBG30 wants 29 3/4 wide by 20 1/2 deep by 10 high. The Sizzler SZR40 scales up to 39 3/4 wide at the same depth and height. Gas stub left-rear. Two 10 square inch opposing vents in the island.

What makes a Summerset easier to live with than its price suggests is the single-piece drawn-stainless firebox — no welded corners to leak, no gasket seams to split. If a built-in has to sit under a cover for most of the year, the Summerset holds up better than the brochure lets on.

Hestan Aspire EB and the premium line — zero clearance

Hestan built-ins are the only grills in this chart that publish a true zero-clearance-to-combustibles rating. The Aspire EB36 wants 35 7/8 wide by 23 1/4 deep by 10 7/8 high. The premium 36-inch Hestan wants 35 1/2 wide by 23 3/4 deep by 11 high. Gas stub center-rear. Both lines ship with factory vent panels and an insulated outer jacket that is what lets them be legal against wood-framed walls.

Hestan’s cutout numbers include a specification buyers often miss — a 2-inch non-combustible bottom requirement under the firebox. On an island with a wood shelf or a raised stone pad, that shelf needs to be stainless, stone, or cement board. Build the base to the spec, not the width.

Install considerations the brochures skip

Gas line sizing by total BTU

A 30-inch Bull Outlaw pulls 60,000 BTU main; a Summit SB38 S pulls 103,000. The rule of thumb is 1/2-inch rigid natural-gas pipe for anything under 80,000 total BTU and 3/4-inch for anything above, assuming a reasonable run length from the meter. If the run exceeds 40 feet, bump a size regardless. Propane runs 3/8-inch flare copper or stainless braided, with the tank located outside the island cabinet.

Counter overhang and hood clearance

The hood, when open, swings on an arc. A 36-inch grill with a hood that stands 20 inches tall at full open wants at least 6 inches of counter overhang in front — the hood apex sits above the counter edge, not above the grill body. 10 to 12 inches of overhang is preferred because it keeps the control panel from steam-burning during normal use. Measure the hood arc before pouring.

Deciding the grill before pouring the counter

The only install mistake worse than a wrong cutout is a committed cutout. If the grill model is not chosen before the island is poured, specify the cutout to the widest and deepest grill under consideration and use a stainless filler frame to shim to a smaller model. A 1/4-inch filler strip is easier to live with than re-cutting stone.

How we keep this chart current

Manufacturers revise cutout dimensions quietly, usually in silent 1/8 or 1/4 inch tweaks that never make it to the marketing brochure. This chart gets rebuilt from the current install-manual PDFs on every product refresh — not from brand sheet downloads, from the actual install manuals linked off the product pages. If a spec here disagrees with what came out of the box, trust the physical manual and let us know; we fix the chart the same day.
