Standard Faucet Hole Size Can Save You Time And Money

For the most common standard faucet hole size you will need a ½-inch hole. This is for your kitchen and bathroom sinks. If you are drilling holes in the granite countertop or other hard material, be sure to measure first before drilling. The measurement of 1/2 inch is not universal. So it’s important to double-check with a measuring tape or ruler if your countertops are made from granite or something like that. You can also calculate the faucet hole size using a faucet hole size calculator.

So you can come to know what exactly Standard Faucet Hole Size is. It’s an industry standard that specifies how big a drill bit should be used when installing new faucets and fixtures. This ensures that the threading on both ends of the pipe can connect properly and securely without leaks or drips when doing any kind of construction work at home or office.

When Would You Think About Standard Faucet Hole Size During An Installation?

It’s a common misconception that the hole size for a kitchen faucet, kitchen sink faucet, water filter faucet, or bathroom faucet is standard. In fact, there are several different sizes of holes depending on where you’re installing your faucet. For example, if you have a kitchen sink with two water sources coming from one pipe then the hole size should be ¾-inch. On the other hand, if you have three or more, then it should be 1-inch only. The following details will let you know the different faucet hole sizes that you should know before installing it.

  • Standard Kitchen Faucet Hole Size: The kitchen faucet hole size is one of the most important factors to consider when buying a kitchen faucet. The standard kitchen sink hole size is 1 ½ inch, but some new homes may have smaller holes that are only ¾ of an inch in diameter. The reason is—this affects how much water can flow out of your tap at once and if it’s too small. This is why it could make it difficult for you to fill up large pots or pans with water. It’s important to double-check before making any final decisions about which type of faucet you want to purchase.

  • Standard Kitchen Sink Faucet Hole Size: The size of the hole in your kitchen sink faucet is determined by the diameter of the spout, but typically this will be 1.25 inches to 2 inches. The pipe threads on a kitchen sink are usually 3/8-inch and require a wrench or pliers for installation.

  • Standard Water Filter Faucet Hole Size: Water filters come with standard size holes to attach it to the faucet. The most common hole size is 3/4″ but there are also 1/2″, 5/8″, and 15/16″ sizes. It’s important to remember that the smaller-sized water filter will need a different type of attachment like an adapter or connector to fit on your water filter faucet.

  • Standard Bathroom Faucet Hole Size: What is the standard bathroom faucet hole size? You may be asking yourself this question if you are a plumber or homeowner. The answer to this question can vary based on your location and what type of plumbing system you have in place. We will help you clarify what the standard size should be for each situation.
  • However, if you live in an area that uses copper piping, then the hole should measure 3/8″ diameter with 1/2″ depth. Or, if your plumbing system is PEX pipe, then there’s no need to drill any holes because it doesn’t use pipes at all.  Because PEX has a small fitting that plugs into a water supply line that has pre-drilled holes beforehand.

  • Standard Bathtub Faucet Hole Size: You may not know what the Standard bathtub faucet hole size is, but it’s important to have this information if you are a plumber or homeowner. If your bathroom doesn’t have an under-sink water heater, then the standard faucet hole size is 1/2-inch for hot and cold. If you do have an under-sink water heater, then there are two possible sizes for the hot and cold faucets—this is 1/2-inch with compression fittings or 3/4-inch with slip fittings. The good news is that most of the tubs come preinstalled with one of these two options. So you don’t need to worry about measuring anything laboriously.

How to Measure a Faucet Hole Size With Slide Caliper?

A Slide Caliper is an accurate measuring tool that can be used to measure faucet hole size. But it has its limitations that it will not give you an accurate result if not used properly. The best way to measure the inside diameter of a hole is using this type of calipers because they are precise and reliable tools for this job with accuracy ranging from +/- 0.001″-0.0015″ (+/- .02mm – .04 mm).

However, there are some drawbacks when you use these types of instruments.  It’s the poor stability—if not held firmly against both surfaces being measured. Or, you will be getting good results while taking at least one free end to make measurements which may cause inaccuracy. It quite depends on your using ability while holding onto each object or tool simultaneously without dropping them altogether. Let’s see how you can use it for measuring a faucet hole size:

  • Use the caliper to determine if there is enough space in between the inside of your faucet hole and any visible pipes.
  • To determine the size of the faucet hole using Venier Caliper, slide-out its scale until it reaches maximum distance.
  • The Venier caliper is a tool for measuring the diameter of drilled holes. To use it, slide out one part until you can see your reading on both sides at once and read off the measurement value indicated by each side’s zero lines.

What Should Be The Standard Spacing of Faucet Hole?

What is standard faucet hole spacing? Standard faucet hole spacing is the distance between two holes usually found around the sink. This measurement is important because it determines what distance of reach you can have for your dishes or pots and pans from the faucet. If you’re looking to install new kitchen fixtures, then knowing this information will help make sure that everything looks great with your current countertop space.

Basically, the most common space is being 4-inch apart from each other on the centerline. But there is also a 3-inch on centerline measurement while some items require measuring at 6 inches or more apart.

However, there are five types of sink faucet hole spacing—Single-Hole, Centerset, Minispread, and Widespread. But Vessel and Wall-Mounted are not so common but also exist as two other choices for faucet holes. Read the details below.

  • Single Faucet Hole Spacing: A single-handle faucet only requires the use of one hole, but if you already have a lot of extra holes drilled into your sink or countertop then an escutcheon plate can cover them up.

  • Centerset Faucet Hole Spacing: In a Centerset faucet, the handles are four inches apart from the spout. So, they have three holes combining both the spout and two separate handles onto one single base. But sometimes, you can get both of these handle mounted onto a singular plate that is six inches apart instead of having them separated between plates or bases altogether.

  • Minispread Faucet Hole Spacing:  Minispreads and Centersets are almost the same. The main difference is that they don’t have a single plate for spout and handles like many other faucet types in the market.

  • Widespread Faucet Hole Spacing: For three-hole sinks, the widespread configuration allows you to place your faucet spout and handle in any position. The average distance between them is six to sixteen inches away from each other.


Widespread Faucet Hole Spacing

  • Vessel Sink Faucet: For tall faucets, the Vessel configuration is ideal. This type of sink has a higher bowl and generally comes with just one handle for the sake of simplicity.

  • Wall-Mounted Sink Faucet: Wall-mounted faucets are mounted onto the wall instead of sitting on a sink. They have long spouts for extended reach and must have ample basin clearance because they come with high basins. So you can use them as extra countertop space.

A Comparison List of Faucet Hole Size And Deck Thickness of Some Popular Brands And Models

The hole size and maximum thickness of a faucet vary from model to model and brand to brand. In the table below, I have listed each make and model’s respective hole size for easy reference as well as what the minimum required deck thickness is should you wish to replace your current sink with one that can accommodate this particular faucet design.


Hole Size And Deck Thickness

Generally, bathroom or kitchen fixtures come in different sizes than standard due to their unique designs–not all sinks are 1 3/8″. However, here’s a list of faucet hole size and deck thickness of various popular models is shown below for your better understanding.

Faucet Brand Model Number Hole Size Max Deck Thickness
American Standard 4175.300.002 1 3/8″ 2″
Bellevue PB-K07CP 1 3/8″ to 1 1/2″ 1 5/8″
Delta 9178-RB-DST 1 3/8″ 2 1/2″

Moen 7185C 1 1/2″ 2 1/2″
Moen 7594ESRS 1 1/4″ 2 1/2″

However, to find out which faucet fits your sink. So you first need to measure the standard size of a hole on your current basin. The average diameter for this is 1 3/8″ with slight variation among different brands and models. Additionally, there mustn’t be too much pressure placed against either end. If the deck has excessive thickness then water may not be able to pass through properly and damage can occur within both ends (the faucet or tap head). So before purchasing any new fixtures make sure you check what kind of maximum thickness dimensions are available.


When installing a new faucet, you need to know the standard hole size. This will help ensure that your water pressure stays consistent throughout the house. There are two sizes of holes available for most residential plumbing fixtures — one is 1-1/8″ and the other is 1-3/8″. The first hole size usually works best with older homes or those built before 1950 because they didn’t have lines that carried high volume water under very much pressure.

So there are many benefits of standard faucet hole size. But it can be difficult to know if this is the best option for your needs. We’ve outlined some merits and demerits so that you can make an informed decision on what will work best for you.

Ultimately, we want you to find the right solution that reduces installation time while maximizing your water flow without worry about leaks or clogs. If you think a different type might better suit your needs, don’t hesitate to reach out or study online.


What can I do for a small faucet hole size?

If you recently purchased a faucet that does not fit your sink’s configuration there are two options available. The first option is to exchange the newly bought item with one that matches the old hole size or increase it yourself by using a power drill. But if this sounds like too much trouble, then hiring someone who is an expert in your area who can do it might be an easier solution for you.

How can I cover extra sinkholes seen for installing the faucets?

Escutcheon plates and single-hole cover plates can be used to fill the gaps between sinkholes. If such a gap is too wide, you should use one of each type of plate instead. Most faucets come with these extra pieces in case they are required for your setup.

Is it possible to drill my faucet hole by myself?

If you are a homeowner you may want to drill your own faucet hole. It is easy and can save some money on installation costs. Remember that this process should be done by an experienced professional if the plumbing system is old or complicated. So if you want to do it by yourself you will also need to know how deep to drill as it needs to be near the water line to work it properly.

How many holes does it need to have a faucet installed?

The number of holes when installing a faucet depends on the type of sink you have. If you have an under-sink or pedestal sink, there will be three or four holes. For a countertop or wall-mount sink, two holes are sufficient. To avoid confusion and ensure the correct installation, measure your thickness before purchasing any new faucets.

What should be an ideal thickness of a faucet hole?

There is a lot of conflicting information out there about what the ideal thickness for faucet holes is. Some say that it is best to have a hole that is 1/8th inch thick, some say ¼ inch, and others recommend ½ an inch. What’s the truth? We’ll explore what each measurement means and why you might want to have one over another.
No doubt, all three measurements are correct depending on your situation. A thinner hole means it will deliver less water flow which would be great if you want to save water using a low-flow faucet fixture in your kitchen sink or bathtub sink. A thicker hole would be better if you are installing a new bathroom sink with high-flow fixtures for high showering.
