Also, it is important that when measuring for the faucet hole size, attention should be placed on the deck thickness. The deck thickness plays an essential role in determining the fitness of the faucet to the basin. If the deck is too thick, the faucet will not fit into the basin, and vice versa. A very thin deck can result in damages to the faucet hole area of the basin. To ensure the safety of the faucet, it is important you find out the deck thickness for the faucet before you buy and use it.

How Can the Faucet Hole Size Be Measured?

To measure the inner diameter of the faucet hole effectively, it is recommended you use a Slide Caliper. The Slide Caliper is one tool that is used to measure the faucet holes accurately. The measuring accuracy for a slide caliper ranges from +/- 0.001″ to +/- 0.0015″ (+/- 0.02 mm to +/- 0.04 mm).


Faucet Hole Spacing

Faucet hole spacing is dependent on the mounting configuration for the specific faucet. It is advised you go for the standard faucet hole spacing to ensure safety in the kitchen. An example of the standard faucet hole spacing is the Centerset, Single-Hole, Minispread, Widespread, Vessel and Wall-Mounted. The two latter types are considered to be the most popular amongst the rest.

So now let’s look at what each faucet hole spacing entails


In the Centerset faucet hole spacing, the handles onto a single plate are four inches apart from the spout. In some cases, there are four inches apart from each other.  Also, there are three holes holding down the spout and two handles onto a single base.


In the single-hole faucet spacing, there is only one hole and it is the commonest type of configuration. However, if the basin is already drilled with extra holes, you can use escutcheon plates to cover them up.


The Minispread- hole faucet works in a similar manner to the Centerset hole faucet. The only difference between both faucet hole spacing is that the spout is not connected to the handle by a single plate.


The Widespread sink hole spacing is typical for faucets with three holes. Here, the spout is set apart from the handle for six to sixteen inches.


The Wall-mounted faucets, as the name, entail the configuration for a sink that is mounted on the wall, not for those sitting at the countertops. Typically, they have ample basin clearance and come with long spouts for long reach.


The Vessel hole spacing configuration is specifically for tall faucets. It is used in sinks that are normally higher than other types of sinks. Here the hole is not drilled into the sink; they normally come with a single handle.
