What if the existing cooktop cutout is too large?

Measure the opening separately from the appliance

The glass or metal top can hide the size and condition of the hole underneath. Use existing documentation where available and arrange safe appliance removal with the appropriate trade when needed. Do not lift or disconnect an appliance yourself just to obtain a quote. Send the exact new model, its installation drawing and whatever existing measurements are already accessible.

Why further cutting does not solve an oversized hole

Removing more stone cannot restore the missing support or reduce the opening. A replacement appliance must suit the installation requirements for its own model. A wide glass top that appears to cover the gap is not by itself proof that the appliance body, supports and required overlaps are suitable. Ask the appliance installer to establish the fitting requirements before proceeding.

Options to discuss before buying

A different model may suit the existing opening. In some situations an appliance manufacturer-approved trim or support solution may be available; confirm compatibility with the supplier and installer. Another option may be replacement of the affected benchtop section. Do not assume a generic trim or stone infill will deliver an acceptable result for every appliance or material.

When a stone infill needs separate assessment

An infill introduces new joins and may create narrow strips around an opening. Matching an older stone’s colour, pattern and finish is uncertain, and reinforcement or support can be complicated. Photos are needed of the entire run, nearby joins, cabinet and underside. Any proposed infill is its own scope rather than a standard cooktop enlargement, and an invisible finish cannot be promised.

Make the enquiry about the fit problem

State that the opening may be too large. Include the present hole dimensions, both appliance model numbers if known and photos showing edges, joins and damage. Standard cutting from $690 + GST is for a suitable agreed cutting scope; it is not a fixed price for rebuilding an oversized opening.
