| What the listing says | Holes | Under the deck | Spread | Adjustable |
|---|---|---|---|---|
| Centerset (4-inch) | 3 | One cast base | Fixed at 4″ | No |
| Widespread — integrated | 3 | Separate pieces, joined by an internal metal tube | Set at one spread | No |
| Widespread — split | 3 | Separate pieces, joined by hoses | As far as the hose reaches, about a meter in practice | Yes |
| Single-hole + deck plate | 3 (two covered) | One body, a plate over the spare holes | None | No |
Four rows. Every one says three holes. No two are the same thing once you look under the deck.
“Three holes” counts the deck, not the faucet
Three holes means the countertop or basin has three openings drilled in a line. That is a fact about the deck. It says nothing about what mounts into it.
A one-hole deck takes a single-lever faucet. A four-hole deck adds a sprayer or a soap pump. Three is the middle count, and the middle count is where buyers get lost — because three different faucet builds all sit in it.
Somewhere along the way “3-hole” got treated as a type of faucet. Several product listings and buying blogs call it “a widespread faucet” outright. That quietly drops two of the three builds. One large retailer’s own single-hole-versus-widespread guide even notes that centerset is also an option, then says it will cover only the other two.
Three holes only ever described the deck.
The one build that’s actually locked — centerset
A 4-inch centerset sits on one cast base under the deck. The spout and both handles are part of that single base, fixed four inches apart. Nothing about it moves.
This is the only one of the three where “three holes” really is one rigid unit. Order a centerset expecting to slide the handles wider, and they won’t go. The four inches is cast in.
The build that adjusts — widespread, and how far
A widespread is three separate pieces on top: a spout and two handles, each in its own hole. What joins them underneath decides whether the spread moves.
We make it two ways. The integrated build runs an internal metal tube between the pieces, set at the factory, so the spread is fixed. The split build joins them with hoses instead. There, the hose sets the limit. The handles sit as far apart as the hose reaches, around a meter in practice. That is well past the 8-to-16 inches most guides quote, though the hose still caps it.
So the word “widespread” on its own doesn’t tell you whether the faucet adjusts. That depends on which of the two builds it is. The three pieces raise a second question too. Each one is coated on its own run, so the spout and handles can drift a shade apart. The widespread finish guide covers why.
The build that isn’t a spread at all — single-hole with a plate
A single-hole faucet can sit on a 3-hole deck with a plate over the two outer holes. It is one body, and the plate is cosmetic. It hides the holes the faucet doesn’t use.
The plate has its own fit rules — width, gasket, a flat deck to seal against. Those match a kitchen deck plate, so there is no reason to repeat them here. They sit in the single-hole kitchen guide and the single-handle bathroom guide. For a 3-hole buyer the point is smaller: a plate covers holes; it can’t turn a single-hole faucet into a widespread.
Why the listing can’t tell you, and what we ask instead
Here is where it bites in an order. Our catalog doesn’t mark whether a model is fixed or adjustable, or integrated or split. The photo and the words “3-hole” read the same across all of them.
In April 2026 a customer came in from a social post, went through the catalog, and picked a 3-hole basin faucet. He took “3-hole” to mean widespread, and widespread to mean he could slide the handles to fit his basin. We walked him through it: some of our models are fixed, some adjust, and which one he had depended on the build.
That was not a one-off email. It comes in every time we run a promotion.
So we work the other way around. Once a customer picks a style, we ask which structure they need — integrated or split — before we build it. I can’t tell you how many buyers assume adjustable until we ask. What I can say is that we ask on every 3-hole order, because the catalog page won’t answer it for them.
Adjustable belongs to the model and its build. The words “3-hole” and “widespread” carry it no further than the label.
What to put on the order instead of “3-hole”
Write the build, not the hole count. Say centerset if you want the fixed 4-inch base. Say widespread if you want the separate pieces. Then say which one: integrated for a set spread, or split if you need the handles to move. Give the center-to-center you are aiming for. If it is really a single-hole faucet going onto a three-hole deck, say that. Note that the plate is only there to cover the spare holes. Put that much on paper and the faucet that ships is the one you pictured. Leave it at “3-hole,” and the picture is ours to guess. The bodies and finishes are on the basin faucet range. The build itself is a short question to settle with the team before anything is made.
FAQ
Is a 3-hole bathroom faucet the same as a widespread?
No. A centerset and a single-hole faucet with a plate also use three holes.
Does a 3-hole faucet adjust?
Only some do. A centerset is fixed, and a widespread adjusts only in its split, hose-joined build.
What is the difference between a 4-inch centerset and a widespread?
A centerset is one cast base with the handles fixed four inches apart. A widespread is three separate pieces. Depending on the build, its spread is either set at the factory or adjustable out to about a meter of hose.
I have three holes — which faucet do I order?
Any of the three families can fit, so the hole count alone won’t settle it. Measure the center-to-center of the outer holes. Decide whether you want the spread fixed or adjustable. Then name the build: centerset, widespread integrated, widespread split, or single-hole with a plate. That is what lets a factory send the faucet you pictured, instead of guessing from a photo.
