Those who spend most of their time in the kitchen understand the importance of having the standard faucet hole size. Most of our time spend in the kitchen when we are at home. Therefore the smallest detail is vital to know about faucets.

At first glance, you think the faucet’s function only provides you with the facility to drain water and wash dishes. But having the right utensil will save you money and energy. The right equipment will help you cook more comfortably, reduce mood swings and consume less time.

Most importantly, ideal-size faucets will enhance your kitchen personality and design. So it’s essential to know some information about kitchen faucets, including faucet hole size. The number of holes in the kitchen sink must be matched with your faucet. But what is the exact faucet hole size should be?

Let’s begin to find out!

What is the Standard faucet hole Size? 

What are the typical diameters of the faucet holes in bathrooms and kitchens? It is specified in various standard faucet specifications that the faucet holes in kitchens and bathrooms are typically 1 3/8′′ which means 1.375 Inches or 34.925 mm in diameter. But the standard size also varies according to various brands and companies.

There is plenty of contradictory information available. As a result, we have outlined key details concerning faucet hole sizes and layouts in a table.

Moreover, the material on this table covers kitchen and bathroom faucets by various brands.

How to measure the faucet hole size: 

You must measure the interior diameter of the faucet using a sliding caliper to determine its total size. These instruments have tolerances between +/- 0.001″ and +/- 0.0015″ (0.02 mm and 0.04 mm). Let’s learn how to quantify this now: 

  • Step 1: 

Position the caliper on the inner jaw while holding it opposite the inside of the faucet hole. 

  • Step 2: 

Move the scale to the outside. Continue doing this until you have traveled the maximum distance. 

  • Step 3: 

At this point, remove your caliper from the jaw. The readout will show you how big your faucet hole is.

How to fix the already wide hole: 

There is no option except to drill a larger hole if an existing one is too tiny. For this purpose, you must need professional assistance.

What is the role of maximum deck thickness: 

The maximum deck thickness is crucial. The faucet could not fit the basin if the deck were too thick. Additionally, the solution might harm the basin’s faucet hole region. Therefore, knowing the maximum deck thickness for a certain faucet is crucial. It is advisable to learn this before purchasing the faucet for any reason.

Problems you can face when your faucet hole is not right: 

If you ignore your daily problems related to faucets, it will completely lead to malfunctions. Faucets at home are the power to ruin your vital occasion, like when important guests are visiting, planning a comfortable night at home, or want to enjoy cooking on Sunday. 

Here are some common problems you can encounter when your faucet hole is not right in place. 

1. Rusting: 

Rust has probably also developed within your faucet if you detect it on the exterior. It’s not a wise decision to consume water from a faucet that has rust, as it might affect tap water quality.  

Rusting is a common faucet issue that develops with prolonged usage. The main cause of this issue is not having the right diameter of the faucet hole. 

 So the water is not drained properly, and water accumulation causes rusting. If your faucet is not rustproof, you cannot prevent it from developing. It’s a warning that you should get a newer, preferably better, faucet model. 

2. Low Pressure 

An issue frequently affects older faucets, including an aerator at the beginning. These small holes can get blocked with dirt and debris and inhibit water flow. Plumbing obstructions and leaking pipes can also cause low water pressure

 Continuous water dripping from the faucet might potentially plug the hole. The constrictor valve within your faucet is more likely to be a problem if the pipes operate normally. 

3. The faucet is not producing any water. 

The issue might also be linked to the valves within older faucets. In recent years, standard faucet designs have included an inside circular valve to collect debris.  

Modern types are more effective and feature many chambers, although they are susceptible to silt accumulation. 

 Check the shut-off valve to see whether it is open while troubleshooting your faucet. If there’s still no water, you must pull the faucet apart and clean each chamber. 

4. Unacceptable faucet noise 

Your house faucet could make noises resembling whistling, yelling, or chattering. This indicates a problem, which necessitates consulting plumbing professionals like Orange Coast Plumbing to look into the cause of the issue. 

 A loose washer is frequently the blame, but if tightening it or changing it out for one of the proper sizes doesn’t work, there could be something wrong with the pipes. 

5. Faulty Faucet Sprayer 

Modern faucets may include a spray hose unit that simplifies washing dishes, cleaning, and washing food. However, with time, this will also begin to break down and cause issues. It could leak, get loose, or stop working altogether.  

Take the pieces apart and look for any possible buildup. If the sprayer has lime and other mineral deposits, immerse it in vinegar for a few hours. Before reinstalling it, make sure it is completely clean. 

6. Overflow

If your kitchen faucet is of poor quality, there is a possibility that the sprayer can break and your home will flood excessively. The flow from pull-down faucets is terrible if a water pipeline bursts at your home. 

Typical faucet hole distance

The faucet hole spacing relies on the installation arrangement of a certain faucet. Also available are faucets with a single hole, center set, mini spread, or widespread drilling. The vessel and wall-mounted types are two more uncommon ones. 

1. Single-Hole 

The single-hole faucet, which only needs one hole, is the most typical design. However, escutcheon plates can conceal holes previously bored in the basin. 

2. Centerset 

The center rack on the center set faucet is four inches from the outlet. Since the nozzle and two handles are combined into one base, they have three holes. Sometimes the faucet’s two handles are separated by six inches and installed on the same plate. 

3. Minispread 

The centers and mini-spread faucets are similar in many ways. 

4. Widespread 

The widespread sinkhole layout is appropriate for three-hole faucets. Furthermore, the nozzle and handle are spaced six to sixteen inches apart. 

5. Vessel 

For high faucets, the vessel design is acceptable. Sinks are also often higher than other varieties. The sink was not drilled into when the hole was made. They often have just one handle. 

6. Wall-Mounted 

Unlike other goods, the wall-mounted faucet is placed on the wall rather than resting on the sink. They typically have long spouts to increase the area of contact. Additionally, they need to have enough basin clearance. 

7. Utilizing Already-Existing Holes 

You’ll need to locate an extra-large escutcheon to fill in the gap if the present hole is somewhat larger. Visit your community hardware or plumbing supply store.


1. How many holes are needed to install a faucet? 

The kind of fixture will determine how many holes are needed to install a faucet. They typically range from single to four-hole fittings where the soap dispenser occupies the fourth hole. 

2. How can more sinkholes be covered?  

You can use escutcheon plates to cover the extra sinkholes. Use single-hole cover plates to conceal the holes if they are too far apart. Extra cover plates are typically included with faucets in case you need them. 

3. Can I drill the faucet hole myself?  

You can, indeed. Use a power drill with a guide and the right bit for the hole to complete the task. Make careful you indicate the precise location of the drilling first. Never drill on the sink without first drilling on a slab or equivalent material. 

 Drilling your sink is simple if you get the hang of it. Be sure to hold the drill firmly. Apply pressure gradually while drilling, enabling the drill to complete the task 

4. What should the faucet hole’s optimal thickness be? 

Device to device differs in the tap hole’s thickness. It is wise to consult the specification to ascertain the maximum deck thickness. 

Bottom lines: 

Even though not all faucets have the same hole size, it is 1 3/8 inches. A 1 1/2-inch hole could be necessary for some.  

If the faucet has three or four holes, your kitchen sink must have holes 6 to 8 inches wide. The distances between widespread faucet holes can be up to 16 inches. 

Most common (non-air-gap) faucets require a hole that is 7/8″ to 1-1/8″ in diameter, with or without associated tubing. There is no ideal faucet hole distance. It varies from brand to brand.
