Cooktop Base Cabinet Planning: Burlington & Waterdown Cutout Guide

A cooktop should be planned as a three-part system: appliance, countertop cutout and cabinet below. Select the exact model first, then use its installation instructions to verify the cutout, clearances, service requirements and space occupied below the countertop. Only after that should the base-cabinet configuration be finalized.

In Burlington and Waterdown renovations, this step prevents a common coordination problem: a drawer, cabinet rail or utility connection occupying the same space the cooktop requires.

Why the cabinet below a cooktop matters

A cooktop body extends below the countertop. Depending on the model, that space can affect drawers, shelves, structural rails and utility routing. The fact that a cooktop is described by a nominal width does not tell you its complete installation envelope.

Use the exact manufacturer's drawing

Record the model number and current installation sheet. Identify the countertop cutout dimensions, minimum cabinet dimensions, required clearances, mounting details and the location of electrical or gas connections. Requirements vary by appliance, so generic dimensions are not a substitute.

Measurements to put on the cabinet plan

• Cooktop overall width and depth.
• Countertop cutout width and depth.
• Distance from cutout to front and back edges as required.
• Depth of components below the counter.
• Clearance required to drawers or shelves.
• Service connection zone.

Decide what storage can actually fit below

Homeowners often want drawers under a cooktop. Whether that works depends on the selected appliance and cabinet configuration. Do not order a standard drawer stack and assume the upper drawer will clear the cooktop body.

Compare base cabinets and drawer cabinets only after the appliance envelope has been plotted on the elevation.

Coordinate the countertop fabricator

The fabricator needs the exact appliance cutout information and should follow its own templating and fabrication process. Confirm the cooktop model before template day. Changing models after the stone is cut can create a serious fit problem.

Plan ventilation as part of the same zone

The cooktop location also determines where the ventilation appliance needs to work. Review the selected hood or ventilation manufacturer's requirements and coordinate upper cabinetry, ducting and clearances separately. Do not infer ventilation clearance from cabinet proportions alone.

Electrical and gas coordination

The service type depends on the appliance. Connection locations must not conflict with drawers, cabinet backs or mounting components. In Ontario, regulated electrical or gas work should be handled according to applicable requirements by qualified trades.

Common mistakes

• Choosing the cooktop after cabinets are ordered.
• Using nominal appliance width as the countertop cutout.
• Ignoring the cooktop body below the countertop.
• Planning a top drawer without checking clearance.
• Putting connections where drawers need to travel.
• Changing appliance models after countertop fabrication.

Pre-order checklist

1. Select the exact cooktop model.
2. Save the installation specification.
3. Plot the cutout on the countertop plan.
4. Plot the below-counter appliance envelope.
5. Check drawer and shelf clearance.
6. Coordinate electrical or gas service.
7. Coordinate ventilation.
8. Confirm the final model with the countertop fabricator.

FAQ

Can I put drawers under a cooktop?

Sometimes, but the usable drawer space depends on the specific cooktop's below-counter dimensions and required clearances. Verify before ordering the drawer cabinet.

Is a 30-inch cooktop cutout 30 inches wide?

Do not assume so. Product names are nominal. Use the manufacturer's specified cutout dimensions for the exact model.

When should the cooktop be selected?

Ideally before cabinet ordering and certainly before the countertop is fabricated. The model affects both the cabinet below and the countertop cutout.

What if I change from electric to gas?

That can change service requirements and trade coordination. Re-review the cabinet, ventilation and connection plan rather than treating it as a simple appliance swap.

Next step

Put the cooktop specification beside your cabinet elevation and verify every overlap. Then select the surrounding base cabinetry and storage configuration around the confirmed appliance envelope.
