Decide on topmount or undermount first
A topmount sink covers the cut edge with its flange. An undermount sink leaves that edge visible and needs suitable finishing and support. Changing mounting styles is therefore more than enlarging a rectangle. Supply the exact template and identify which part of the opening will be visible. Rounded corners, flange coverage and cabinet width can determine whether the new fitting works with the old stone.
Plan the handover to your plumber
The cutting quote concerns the agreed stone modification; sink removal, pipework and reconnection are separate unless expressly included. Ask your plumber about the bowl depth and waste position before confirming the replacement. For your Robina enquiry, send a cupboard photo and mention any filter system, disposal unit or fixed shelf under the sink. Access to the property and the kitchen must also be confirmed for the scheduled Gold Coast visit.
Quote and scheduled Queensland visits
Send your Robina address, clear photos, the material if known and current and proposed dimensions. Queensland jobs are coordinated through scheduled visits; availability is confirmed for your address and accepted scope. Standard cooktop or sink cutting starts at $690 + GST per cut, and tap-hole drilling starts at $350 + GST for the first hole; each additional hole at the same visit is $100 + GST ($110 including GST). Other modifications are quoted for the actual cutting, finishing and access. Appliance, plumbing, electrical and cabinet work should be identified separately.
Suitability before the visit
We assess the existing installation, including cracks, joins, narrow stone rails and support. Work on legacy engineered stone is considered only within permitted scope and applicable requirements. Do not make a trial cut or remove a connected appliance to provide measurements. Send the product documents and accessible photographs first so the next step can be confirmed.

Questions, answered.
Can I change to undermount without replacing the stone?
Sometimes an assessment is worthwhile, but the old hole may be the wrong shape or have an unsuitable edge. A different sink or replacement section may be more practical.
How do I arrange stone cutting in Robina?
Send your suburb, photos and fitting specifications through the quote page. We review the proposed modification and confirm the written scope, price and available appointment before you coordinate other trades.
