Ensure the faucet you select will fit your sink or basin because not all bathroom sink faucets are compatible with every sink. Centerset, single-hole, and broad faucet drillings are the most common types. You may decorate and adorn your area with various bathroom sink faucet designs, styles, finishes, and functions.
Are all Faucet Holes the Same Size?
The diameter of a standard faucet hole size is 1 3/8 inches. However, since not all faucets are created equal, some will need a 1 1/2-inch hole. Before mounting a faucet or drilling a hole in the countertop, it’s also crucial to measure the depth of the sink. The deck may not fit the faucet properly if it is too thick. Depending on the sort of faucet you want to install, faucet holes should be the correct thickness and size. The water flow from the water tanks is proportionate to the faucet hole diameter.
Standard Faucet Hole Size
The sizes of the holes in the kitchen and bathroom are standard; however, they may vary between manufacturers and models.
| Hole Size | Max Deck Thickness |
|---|---|
| 1 ¼” | 2 ½” |
| 1 ⅜” | 2” |
| 1 ¼” to 1 ½” | 3” |
| 1 ⅜” | 1 ⅜” |
| 1 ⅜” | 1 ⅜” |
| 1 ⅜” to 1 ½” | 1 ⅝” |
| 1 ½” | 2 ½” |
| 1 ⅜” | 2 ½” |
| 1 ¼” to 1 ½” | 2 ¼” |
| 1 5/16” | 2 ½” |
Standard Kitchen Sink Faucet Hole Spacing
The sink is often in the middle of the faucets. When measured from the center of one hole to the next hole, holes are drilled 4, 6, or 8 inches apart.

A bathroom cabinet with a countertop is called a vanity. Check the on-trend vanity bathroom ideas if you take interest. The countertop itself has apertures for the faucet and sink fittings and provides room for toiletries near the sink. You may keep additional toilet paper rolls, cleaning materials, cosmetics, and grooming items in the space beneath the countertop.
| Type of Vanity | Hole Size |
|---|---|
| Double Vanities and Single-Sink Vanities | 60 and 72 inches |
| Standard oval and round designs | 16 to 20 inches in diameter |
| Standard rectangular sinks | 19 to 24 inches in width and 16 to 23 inches in length. |
Countertop Faucet
Drop-ins and under mounts are the two standard layouts for bathroom sinks. Sink drop-ins are the ones that have a lip that rests on the countertop. You have an under mount sink if it is fixed to the base of the counter.
Sink Faucet
A “widespread” or “eight-inch spread” faucet is required if the space is six inches or greater. For faucets that use all three holes in the sink, you need one that is “centerset,” “mini-spread,” or “four-inch spread” if the measurement is less than six inches.

The individual manufacturer and type of the faucet will determine the installation instructions.
Most common (non-air-gap) faucets require a hole that is 7/8″ to 1-1/8″ in diameter, with or without associated tubing. Most conventional faucets may be installed without difficulty in holes up to 1-1/8″.
Standard Hole Size or Bathroom Faucet
Unless otherwise specified in the specification, faucet holes in kitchens and bathrooms are typically 1 3/8′′ (1.375 Inches or 34.925 mm) in diameter.

Modern shower heads typically have a 1/2-inch thread size. Select the style of shower head you want without worrying about fit because the size of shower head threads is regulated. The primary element is the drilling procedure. Therefore, the size of the shower valve hole is not standardized. The size of the shower valve determines this.
Faucet Hole Spacing
#1 Single Faucet Hole Size
Knowing some details about sink faucets, such as the typical hole size and spacing, and whether you intend to install or replace a kitchen faucet in your home is crucial. The recommended hole size for faucets is 1 3/8 inches, or 34.925 millimeters, according to the majority of manufacturers. However, certain kitchen faucets can need a 1.5-inch hole that is wider. The volume of water flow increases with the size of the hole.
#2 Wall-mounted
As its name suggests, wall mounted automatic faucets attach to the wall behind a sink and give the feeling that they are floating above it. They are a well-liked option for educational, healthcare, and commercial uses in lavatories and kitchens. The supply pipes are hidden behind the wall but function like any other faucet. Although it might seem slightly different, it requires careful planning before installation. Wall mounts, for starters, do away with the necessity for faucet holes in the sink or countertop.
#3 Vessel
The vessel sink basin can be built of any material, and it is designed to sit on top of a bathroom vanity unit or counters instead of being insets like typical drop-in or under-mount sinks. Vessel sinks can be made of fired ceramic, glass, stainless steel, stone, copper, or marble. More precisely, vessel sinks are frequently utilized in purely cosmetic bathrooms, such as powder rooms or guest restrooms.
#4 Minispread Faucet Spacing
The basin of a vessel sink can be built of any material, and it is designed to sit on top of a bathroom vanity or counters as opposed to being insets like typical drop-in or under-mount sinks. Vessel sinks can be made of fired ceramic, glass, stainless steel, stone, copper, or marble. More precisely, vessel sinks are frequently utilized in purely cosmetic bathrooms, such as powder rooms or guest restrooms.
#5 Centerset Faucet Holes
One to three-hole sinks and countertops can use this kind of faucet. This design combines the handles and spout into a single deck plate. Centerset faucets, a common faucet design, require holes with 4″ centers, which is the distance between the centers of the left and right holes.
#6 Widespread Faucet Holes
When viewed from above, this wall mounted automatic faucet appears to have nothing connecting the knobs to the spout. The version for bathroom counters is a widespread miniature faucet. In a broad faucet, knobs and faucets are attached separately to the sink or countertop without a deck plate. Your countertop or sink needs multiple holes drilled into them for installation. Widespread faucets need holes with centers that range from 8″ to 16″. Widespread faucets, also referred to as non-deck plate faucets, are the most popular choice.
#7 Bathroom Faucet Hole Spacing
The bathroom faucet hole spacing depends on where you live and the plumbing system you have in place. If your neighborhood uses copper pipe, the hole should be 3/8″ in diameter and 1/2″ deep. Alternatively, if your plumbing system uses PEX pipe and doesn’t use any pipes, there is no need to drill any holes because PEX has a tiny fitting that connects to a water supply line with previously drilled holes.
#8 Kitchen Faucet Hole Spacing
Although 1 1/2 inches is typical for kitchen faucet hole spacing, some newer homes may have 34-inch holes instead. If your tap is too small, it will affect how much water can come out of it at once. Because of this, it could be challenging for you to add water to big pots or pans. Before making any final judgments regarding the kind of faucet you intend to buy, it’s crucial to verify again.
Common FAQs Before Drilling Holes for Faucet Installation
Is there a required number of holes for a faucet installation?
The type of faucet you intend to install determines how many holes are necessary for installation. The number of holes in a faucet typically ranges from one to four, with the fourth hole used for a soap dispenser. A center set faucet needs four inches of clearance for typical hole spacing.
How can I cover extra sinkholes seen for installing the faucets?
You need to add additional accessories to a sink that has extra holes. The simplest and least expensive solution is to acquire faucet hole covers to cover and plug the other sinkholes.
What can I do if the faucet is too small to fit my sink?
Set up a drill with a grinding bit to enlarge a sinkhole that is too tiny for a faucet. Measure the needed hole size for the faucet once the drill is ready. Now use the drill to grind in a circular motion along the sinkhole’s edges for an equal finish.
What is the ideal thickness of the faucet holes?
Depending on the sort of faucet you want to install, faucet holes should be the correct thickness and size. The water flow from the water tanks is proportionate to the standard size of a faucet’s hole.
The recommended hole size for faucets is 1 3/8 inches, or 34.925 millimeters, according to the majority of manufacturers. However, certain kitchen faucets can need a 1.5-inch hole that is wider. The volume of water flow increases with the size of the hole.
Is it possible to drill my faucet hole by myself?
A ceramic drill bit and a 33 mm diameter carbide-tungsten drill bit are required to drill the sink. For drilling, an operator is preferable to a drill. The operator doesn’t have a more decisive kick, either. The impact won’t be used at all. The operator is heavier in kg but moves slower. Wattage, too. If you don’t have an operator, you should use a drill instead, but slow it down to prevent the drill bit from becoming worthless.
Drilling Holes for Faucet
Ensure the sink’s underside is clear before you drill to avoid drilling into bracing or other barriers that would make installing the faucet challenging or impossible.
Check Standard Faucet Hole Sizes
It’s crucial to understand the typical sink faucet hole size and faucet hole spacing if you intend to install or repair a faucet in your home. The number of holes in the sink and the distance between the holes in your new faucet must match. Sinks and faucets can be installed in various ways, but if your faucet doesn’t fit, you can usually make modifications. Below are the famous Faucet Brands worldwide to help you choose a kitchen faucet hole spacing that works for you.
| Brand | Role | Part number | Hole sizes | Max Deck Thickness |
|---|---|---|---|---|
| Grohe | Best Germany Kitchen Faucet Brand | 20193000 | 220mm x 220mm | 1/2″ |

Measure Faucet Hole Sizes
- Get a basin wrench and a basic plumbing tool, and undo the bolts holding the water lines in place—you’ll need to unscrew both nuts—to remove the existing faucet. There should only be one nut to loosen if your faucet has just one handle.
- You might need to remove the faucet, which will require some tools if you can’t see or measure the holes underneath. The incoming water lines can be found under the sink, so start there. One will be for hot water and the other for cold water. Look for little handles called shut-off valves that turn off the water to the faucet when moved in a clockwise direction. You must stop the main water supply if you don’t have shut-off valves. Turn on the faucet to remove any remaining water in the pipes after the water has been turned off.
Install with Existing Hole Sizes
You’ll need to find an extra-large escutcheon to fill the gap if the present hole is slightly larger. Visit your neighborhood hardware or plumbing supply store. There is no option except to drill a larger hole if an existing one is too tiny.
Drilling Holes for Faucet Installation
In most cases, drilling small holes in a stainless steel sink is simple. The cone-shaped “Unibit” that drills a hole in granite for faucets is an increasingly larger hole that works excellent for stainless sinks. A good sharp “hole saw” is your best option for hardware-store quality tools. A 1/2″ hole, for example, can be drilled with a standard metal bit from the hardware store. It’s easiest to drill a small pilot hole, then follow with a 7/16″ or 1/2″ bit. Many of the contemporary sinks, even those that seem to be made of porcelain, are actually relatively thin and simple to drill holes in the countertop for the faucet with a masonry drill bit. If unsure, get guidance from the maker of the sink.
Conclusion
Deciding how many holes and the size of your sinks you want your house to have is certainly a challenge. But with the help of this article, you can now easily determine your preferred measure of faucet holes. For more information, visit oltsw.com.
