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.

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

Centerset

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.

Single-Hole

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.

Minispread

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.

Widespread

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.

Wall-Mounted

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.

Vessel

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.

Frequently Asked Questions (FAQS)

How Can You Cover Extra Sink Holes?
