Cooktop cutouts and clearances

A new induction cooktop rarely drops cleanly into the hole an old gas unit leaves behind. The cutout width, depth or corner radius usually differs, and finding that out at template rather than at install keeps the job from waiting on a second piece of stone.

What the cutout actually needs

A cooktop cutout is not a generic rectangle. Every model has its own cutout width, depth and corner radius, published by the manufacturer, and we work from that spec sheet rather than from the old appliance sitting in the kitchen. Two ranges that look interchangeable in an appliance store can call for cutouts an inch apart in width, and a slab is not the place to find that out.

Why the old hole is not a safe guide

Homeowners often assume the new range will match the old one, especially when both are the same brand. Cabinet openings get resized during a remodel, control layouts move, and knobs or touch panels sometimes need extra clearance behind the front edge. We ask for the new model number at template, not at install, so the cutout drawing reflects the appliance that is actually going in the kitchen.

Clearance to walls, cabinets and the sink

Code and manufacturer specs set minimum clearance from a cooktop to a side wall, a cabinet, and any combustible surface nearby, and gas ranges carry their own ventilation requirements above the unit. We also keep enough stone between the cooktop cutout and a sink cutout so the slab has structural integrity between the two openings. On a narrow galley kitchen this can mean shifting the cooktop location slightly rather than crowding two large cutouts side by side.

Support under a downdraft or slide-in unit

A slide-in range that rests on the cabinet below needs the base cabinet built to the right height and depth before template, because the slab sits on top of it like any other section of counter. A downdraft cooktop adds a second consideration: the ductwork below has to clear the cabinet structure, and the cutout position has to line up with where that duct actually runs, not just where the drawing shows it.

What we confirm before cutting

At template we confirm the exact model, pull the manufacturer's cutout template or spec sheet, mark the cutout location on the digital template, and check clearances against the surrounding cabinets and any nearby sink. We flag anything that looks tight (a narrow peninsula, a cutout close to a wall) before the slab goes to the saw, because a cutout is one operation we cannot redo without ordering another piece of stone.

Peninsulas and small kitchens

A peninsula cooktop with cabinets or a wall close on two or three sides is the tightest layout we template, since the manufacturer's side clearance and the available counter width sometimes leave very little margin. On a small galley kitchen we will often talk through moving the cooktop a few inches, or choosing a narrower model, before the layout gets locked in, rather than discovering the conflict once the slab is already cut.

Getting the appliance detail right on your end

The single biggest help on a cooktop job is the actual model number and, if you have it, the manufacturer's cutout spec sheet, before template day. If the appliance is not chosen yet, tell us and we will build in reasonable clearance so the final choice still fits. Either way, the cutout gets checked against the real dimensions before anyone picks up a saw.

A cooktop cutout is a small detail on paper and a hard one to fix after the fact, so we treat it as its own step rather than an afterthought to the rest of the layout.
