The sink cutout is the most precise, least forgiving cut in the whole job. When the counter shop supplies the sink too, a whole category of expensive surprises disappears.
Plenty of our clients show up with a sink they bought online, and we make it work — that's part of the job. But when we supply both the top and the sink, the job gets measurably better, and it's not a sales pitch to explain why. It's geometry.
The cutout is cut to the actual sink
An undermount sink cutout is CNC-machined to follow the sink's bowl within about a sixteenth of an inch. When the sink is ours, we're cutting to a model we've templated dozens of times — or to the physical sink sitting in our shop. When the sink is arriving “sometime this week” from a marketplace seller, we're cutting to a PDF that may or may not match the casting that shows up. A sink that arrives 3/8” different from its spec sheet is a delayed job or a compromised fit.
The reveal is a decision, not an accident
On an undermount, the “reveal” — whether the stone overhangs the bowl, sits flush, or shows a lip of sink rim — is a real design choice, and each option changes the cutout dimensions. When sink and stone come from one shop, you pick the reveal at templating and we machine exactly that. It's also our crew setting the mounting rails and clips, so the sink's support is engineered with the stone, not improvised under it later.
What one-shop accountability gets you
- No schedule roulette — the sink is in our warehouse before we ever cut stone.
- A cutout polished and machined for that exact bowl, at the reveal you chose.
- One warranty conversation: a chip at the cutout, a loose mount, a leak at the rim — one phone number, no finger-pointing between a counter shop, a plumber, and an online seller.
- A cleaner plumbing handoff: your plumber connects a sink that's already perfectly set, level, and sealed.
- Honest pairing advice: bowl depth vs. cabinet, gauge vs. garbage disposal, workstation ledges vs. faucet spread — we've lived every combination.
And it usually doesn't cost more
We stock sinks from SinkSource, MSI, Blanco, and Kohler at prices competitive with the big online retailers — browse them all on our sinks page. Bundled with the countertop, the package price typically lands within a few dollars of DIY sourcing, minus every risk above. Sometimes the boring answer is the right one: buy the hole and the thing that goes in it from the same people.
