A small hole needs a considered position
A tap hole must fit the fixing shank and leave room for the base, handle and hoses. Send the manufacturer’s required hole diameter and mounting instructions. The width of the visible tap base does not tell us which hole to drill.
New holes, enlargements and replacement taps
Tell us whether you need a completely new opening or an existing hole enlarged. Include the current hole diameter, proposed centre point and any nearby sink opening, stone edge or join. An enlargement depends on the condition of the surrounding stone and how the new fitting will cover the opening.
Clearance above and below the stone
A good position must work on both sides of the benchtop. We review the sink bowl, clips, cabinet rails and access for the fixing nut below, plus the splashback and handle movement above. A photo from underneath is often as helpful as a photo of the surface.
Quote and installation planning
Tap-hole drilling starts from $350 + GST ($385 including GST) for the first hole; each additional hole at the same visit is $100 + GST ($110 including GST), as shown on our pricing page. The written quote confirms material, access, number of holes, finishing and any travel. A plumber installs and connects the tap; the cutting quote covers the agreed stone work.

Cutout questions, answered.
Can you drill a tap hole in an installed stone benchtop?
Suitable installed stone can be assessed for on-site drilling. We check the material, condition, edge distances, support and access before accepting the job.
What size hole does my tap need?
Use the installation instructions for your exact tap model. Hole sizes and fixing arrangements vary, so send the model and manufacturer drawing before a hole is marked.
Can a new hole hide an old tap hole?
Moving a tap usually leaves the old opening behind. A cover or repair may remain visible. Send photos of both positions so the options can be discussed before drilling.
