Who handles the worktop cutouts, and when are they confirmed?

Cutouts are usually machined at the factory according to drawings, not cut on site. The confirmation point is at the re-measurement: the actual dimensions of the sink or cooktop, or a cutout drawing, are required, as any deviation directly affects worktop strength and edge finishing. If the appliance is purchased later, it is advisable to reserve according to common specifications first, then verify against the actual item.
