Countertop cutouts are the one step in a countertop that cannot be revised. Once we cut the opening for a sink, a cooktop or a faucet, it is permanent. That holds in every material we fabricate, natural stone and engineered alike.
There’s one honest qualifier. A hole can sometimes be enlarged, depending on the material and the layout.
It cannot be made smaller. It cannot be moved over. And it cannot be put back the way it was. Enlarging and undoing are not the same thing.
Everything else about a cutout follows from that. What it costs, what makes one harder than another, and what has to be settled before anybody cuts stone. And at the end, what we can actually do for you if your countertop is already in.
What a Countertop Cutout Actually Is
A cutout is any opening we take out of the middle of a slab. On a typical kitchen there are three kinds. The sink opening, the cooktop opening, and the faucet holes behind them.
None of it happens in your kitchen. Your slab goes on the CNC bridge saw or the waterjet and gets cut to the template we built off your cabinets as they actually sit. By the time the truck pulls up at your house, every opening in that stone is already exactly where it’s going to be.
That’s why the decisions come early. On install day there’s nothing left to decide about a cutout, because the deciding happened before the stone was cut.
What Makes One Cutout More Complicated Than Another
A cutout gets complicated when it’s more than a standard opening in an open, easy-to-work-with run of countertop. A simple round faucet hole is one thing. A large undermount sink opening with a polished interior edge is another. Five things move a cutout from routine to careful.
The Shape of the Opening
Size is the obvious part. Shape is the part people underestimate.
A rectangle with generous corners is easy work. An opening with tight inside corners, an irregular outline, or a shape that has to follow a specialty fixture takes longer and carries more risk. Every inside corner is a place where stress collects, which is why we finish them in a radius and never in a sharp point.
Where It Lands on the Slab
An opening close to the front or back edge leaves less stone to carry the load around it. So does one near the end of a piece, near a seam, or beside another cutout. There’s less stone left in front of a sink than almost anywhere else on a counter, and that strip is the part we handle most carefully.
It’s also where most of the damage we get called out to look at shows up, and whether a crack there can be repaired depends a great deal on exactly where it runs.
We don’t work from a chart here. We work out how much room an opening needs when we lay your slab out, against the actual piece and the actual fixture. If your layout is tight, tell us at the estimate and we’ll look at it with the measurements in front of us, not after the fact.
The Finished Inside Edge
An undermount sink opening has its cut edge on show. Nothing sits over it, so it gets polished to the same standard as the outside edge of your counter. That’s real finishing work, and it’s the single biggest difference between an undermount cutout and a drop-in one, where the sink’s rim covers the cut.
There’s a reveal decision that comes with it too. It’s whether the stone sits slightly inside the bowl, slightly outside it, or dead level with it, which the trade calls a positive, negative or flush reveal. The three look different and they live differently, so we go through them with you before anything is cut. That’s not a decision to let happen by itself.
The Fixture Itself
A standard drop-in sink is simple work. A farmhouse sink, a handmade sink or a specialty fixture with unusual corners is not. An unusual rim adds time. So does an odd mounting system, or an installation instruction that dictates how the opening has to be cut.
A farmhouse sink is the clearest example. The counter meets it on three sides instead of sitting over it, so the sink and the cabinetry built for it both have to be finished and in place before we template.
The Material
Material changes how an opening is cut and how much care it takes.
Porcelain is very hard, and an exposed cut edge can chip if it’s not finished properly. That’s why cut edges get treated, which is routine fabrication rather than a sign of a problem. Farmhouse and irregular openings in porcelain are the one thing I’d talk you out of, because those cuts work against the stability of the panel.
Heavily veined natural stone, and slabs with natural fissures or fragile areas, get evaluated before we cut. I want to know where an opening is going to land relative to the movement in a slab before anything happens to it, so the hole doesn’t end up somewhere the stone is weak. That evaluation is part of laying the slab out, which we do before a blade touches it.
All five come back to the same thing. The hole itself is not the issue.
The cutout has to fit the fixture and have enough stone around it. It has to work with the cabinet and the plumbing underneath. And it must not leave a weak spot in a countertop you’re going to live with for a long time.
What Customers Get Wrong About Cutouts
The biggest misunderstanding is that a cutout is something that can be changed later without much trouble. Four more come up almost as often.
“The manufacturer’s template will do.”
It will not. Manufacturer templates are typically off in their measurements, and we won’t cut a permanent opening from a paper template, an online drawing or a product photo.
We need the sink itself. That lets us check its real size and shape, its rim, and exactly where the opening has to sit.
“Any sink will fit once the countertop is in.”
The sink has to work with more than the countertop. It has to suit the cabinet opening underneath it, the depth of your top, and the faucet layout going in behind it.
A sink that looks right in the catalog and is too wide for the cabinet below is a problem nobody finds until somebody opens that cabinet door.
“A cooktop cutout is a standard size.”
Cooktops are not standard. Cutout size differs between them, and so does how they mount and how much clearance they need. Their installation instructions differ too. We need the exact model before we cut, not the brand and not a width taken off the old appliance.
I would rather wait on a model number than cut a rectangle to the wrong specification. There is no second attempt.
If you’re looking at an invisible induction unit that mounts under the surface, that’s its own conversation, because the section of countertop it sits in cannot carry any cutouts at all.
“A hole is just a hole.”
They are not interchangeable. A faucet hole and a polished undermount sink opening are different operations. So are a rectangular cooktop opening and a farmhouse cut.
Each one needs its own layout, its own cutting, its own finishing and its own handling. The word covers four jobs with almost nothing in common except that stone comes out of the middle.
What Countertop Cutouts Cost, and What the Price Covers
Cutouts are itemized on our estimates and stated up front, so you see them before the job starts and not afterward. A cooktop cutout runs $150 to $250. A sink cutout runs $200 to $340, depending on complexity and whether you’re going undermount. Faucet holes are included with your sink cutout at no extra charge.
Faucet holes are a few minutes of work once the sink cutout is already being made. Charging for them separately is technically defensible, and we’ve chosen not to.
If you want to see where cutouts sit against every other line on a countertop estimate, our breakdown of what a countertop quote actually includes goes through the whole list.
What the Sink Cutout Charge Actually Covers
People read the cutout charge as payment for drilling, and drilling is only part of what’s in it.
What sits inside that $200 to $340:
- Laying the opening out on your slab
- Verifying the fixture against the real thing, not against a drawing
- The equipment and tooling it takes to cut stone accurately
- Fabrication time
- Finishing the interior edge, where an undermount leaves it exposed
- The extra handling risk once there is a hole in the middle of a large piece of stone
That last one matters more than it sounds. A countertop is at its most vulnerable after the openings are cut, because a piece of stone with a sink opening in it is a much weaker thing to lift and carry than the same piece was before the cut. Every hand on it from that point on is being careful.
Decide These Before We Template
Three things have to be settled before we build your template, and all three are decisions only you can make.
The sink, physically on site. Please have the actual sink at the house before the template visit. Not ordered, not on the way, here where we can put hands on it. This matters most with undermount, specialty, handmade and vessel sinks, and with anything bought online.
The faucet, and everything else that needs a hole. We need the configuration, whether that’s single-hole, widespread or something else, because those holes are permanent too. Please tell us about a soap dispenser, an air switch, a filtered water tap or an instant hot at the same time. Every one of those is a hole, and every hole is a decision you make once.
The cooktop, by model. The model number is what we work from, because that’s what carries the cutout specification and the clearances.
There’s more to a template visit than the cutouts, and what actually happens on template and install day covers the rest of it.
The best time to change your mind about any of this is before we template and fabricate. After that, the sink opening, the cooktop opening and the faucet holes are permanent, and the only conversation left is about what can be done with a top that is already in.
What If the Countertop Is Already Installed?
Some people find this article too late. The counters are in, the sink is in, and they want a bigger one.
We do take that work on, including on countertops we did not install. It is a real service and not a polite referral. There are two things to understand first, and the second one is why I would rather you read it here than hear it for the first time on the phone.
It does not happen on site. The top comes out and comes back to our shop. That’s the only way to do the cutout properly, with the piece on the machine and the interior edge finished the way it needs to be. Cutting an installed top in place is a different job and it does not produce the same result.
The material decides whether taking it out is realistic. Quartz comes out without breaking. Enlarging an opening in an installed quartz top is workable, and that’s the easy version of this conversation.
Granite is the risk. The sink is secured underneath with adhesive, and granite can break as the sink comes away. If it breaks, the countertop around the sink will need to be replaced. Sometimes it can be repaired, but that is not something to count on.
Here is where I will be direct with you. Removing an installed granite top to enlarge an opening carries real risk, and you need to understand that before you decide, not afterward. I’m not telling you not to do it. I’m telling you what we’re walking into, so the decision is yours with the facts in your hand.
Send us a photo of the top and the sink you have in mind, and tell us what the material is. That’s enough for us to tell you which of those two conversations you’re in.
This is not the same as swapping a drop-in sink for an undermount in a top you already own. That’s a different job with a different answer, because the existing opening was cut for a rim to cover it. We go through why that one is almost never worth attempting separately.
Frequently Asked Questions
Why do sink cutouts vary in price?
Our sink cutouts run $200 to $340. Two things decide where a job lands in that range. The first is whether the sink is undermount, because an undermount leaves the cut edge on show and it has to be finished, while a drop-in rim covers it. The second is the shape of the opening. A plain rectangle is quicker than one that has to follow an unusual fixture. Faucet holes are included either way, so they’re never what moves the number.
My sink is on backorder. Can you template without it?
We need the actual sink at the house before we template, because we cut the opening to your real sink and not to a drawing. Manufacturer templates are typically off in their measurements, and a sink opening is not something anybody gets to cut twice. So please tell us as soon as you know a sink is delayed. We’d much rather schedule the template around the delivery than measure early and hope the sink matches its paperwork. Telling us early costs nothing. Finding out on the day costs everybody a trip.
What if I want a soap dispenser, an air switch or a filtered water tap?
Tell us before we fabricate. Every one of those needs its own hole in the countertop, and a hole is permanent the moment it is drilled. We need to know what is going in and where you want it, along with your faucet configuration, whether that’s single-hole, widespread or something else. This is an easy one to leave until the countertop is already in, and it’s the decision with the least room to fix afterward. If you’re torn between two setups, tell us both and we’ll talk it through before anything is cut.
What happens if a cooktop opening ends up bigger than the cooktop?
An opening cannot be made smaller once it has been cut. That is the whole reason we ask for the exact cooktop model before fabrication, not the brand and not a measurement taken off the old appliance. Cooktops differ in cutout size, in how they mount and in the clearances they require, so two units that look alike side by side can still need different openings. If you’re already looking at an opening that does not match your appliance, send us photos and we’ll tell you what we’re actually looking at instead of guessing over the phone.
