Faucet Knowledge

VIGA shows you know what is the standard faucet hole size in kitchen and bathroom.

A good friend of mine suggested that I write down the size of faucet holes in kitchen and bathroom. After research, I wrote this article to share my findings with you.

What is the standard faucet hole size in kitchen and bathroom? Unless otherwise specified in the specifications, the standard faucet hole diameter in kitchen and bathroom is 1 3/8 inch (1.375 inch or 34.925 mm). However, the size of faucet holes may vary depending on the specific brand and model.

I know there may be a lot of confusing information there. Therefore, I have detailed important information about the size and configuration of faucet holes. In addition, the information provided in this paper is related to faucets in kitchens and bathrooms. Therefore, please continue reading.

Comparison of hole sizes of several faucets
Depending on the specific brand and model, the size of faucet hole may be different from the standard 1 3/8 “. To illustrate this point, you will find a random list of bathroom and kitchen faucets below. In the following table, I list the hole size and maximum panel thickness of each model.

As shown in the above table, the standard faucet hole is usually 1 3/8 “,which is slightly different between different models.

The maximum deck thickness also plays an important role. If the deck is too thick, the faucet may not be suitable for the basin. Furthermore, the solution may result in damage to the faucet hole area of the basin. Therefore, it is important to find out the maximum panel thickness of a specific faucet. For this reason, it’s best to find out before buying a faucet.

How to measure faucet hole size.
The best way to measure the inner diameter of faucet hole is to use vernier caliper. The measuring accuracy of such tools ranges from +/- 0.001 inches to +/- 0.0015 inches (+/- 0.02 mm to +/- 0.04 mm). Therefore, using this tool to measure faucet holes will produce accurate results.

Venier caliper
Place the inner jaw of caliper against the inside of faucet hole.
Slide the scale outward until the maximum distance is reached.
Slide out the caliper, and the indicated reading will be the diameter of faucet hole.
Standard faucet hole spacing
The faucet hole spacing depends on the installation configuration of the specific faucet. In addition, the standard tap hole drilling is a single hole, with center set, minimum expansion or extensive expansion. Moreover, the other two less common types are “boat” and “wall-mounted”.

Single-hole faucet only needs one hole, which is the most common configuration. However, if additional holes have been drilled in the basin, the hole cover panel can cover it.

Central set
In the Centerset faucet, the handle is four inches away from the nozzle. Therefore, they are three holes, combining the nozzle and two handles on one base. Sometimes, a faucet may have both handles mounted on a single plate six inches apart.

Small price difference
The Minispread is roughly the same as the Centerset. The difference is that the nozzle and the handle are not connected by a single plate.

Widely used
Wide sink hole configuration is suitable for faucets with three holes. In addition, the distance between the nozzle and the handle is six to sixteen inches.

The container is configured for a high faucet. Moreover, the receiver is usually taller than other types of receivers. In addition, the hole is not drilled into the sink. Typically, they have a single handle.

Wall hanging type
Wall-mounted faucets don’t sit on the sink like other faucets, but are mounted on the wall. Usually, they have long mouths to expand their range. Moreover, they must have enough clearance for washing the pool.

Related issues
My faucet hole size is too small for the recently purchased faucet. What am I supposed to do? You have two choices. One is to replace the recently purchased faucet with a faucet that matches the configuration. Or, increase the size of the hole to accommodate the purchased faucet. You can use an electric drill to do it yourself, or you can hire professionals in your area.

How to cover the extra sink holes? You can cover additional sink holes with the hole cover panel. If the distance between holes is too far, they can be covered with a single hole cover plate. Most faucets have extra covers for your use when you need them.

What is the ideal thickness of faucet hole? The thickness of faucet hole may vary from lamp to lamp. Therefore, it is wise to refer to the specifications to find out the maximum panel thickness.
