If you're looking to switch up those faucets for your kitchen and give your sink area a little makeover, one thing you need to know is that the hole sizes aren't one-size-fits-all. See, different sinks have different hole diameters, so you can't just grab any old faucet and expect it to fit like a glove.
The standard size hole for a kitchen faucet is typically 1 3/8 inches (35 mm) in diameter, as per industry norms . This size is commonly used for the mounting hole in most kitchen sinks. It's important to note that this is a general standard, but variations may exist.
No, there is a variety of kitchen faucet styles and fittings, and the right style will depend on your home's design.
The exact plug size will then depend on what kind of fitting the drain has, but 1 ¾ inches is usually considered the 'standard' size for modern plugs. Most hardware and DIY stores will offer a range of plugs to fit that size, so you can choose whatever style or colour plug that you wish.
Kitchen taps come in many sizes in terms of the height of the neck and the spout. But their base sizes range from 44-60mm, all of which fit into a kitchen sink's standard size pre-drilled tap hole of 35mm.
Whether you have a single or double basin sink, the standard, universal drain hole diameter is 3-½”, this size ensures compatibility with other drain assemblies or garbage disposals.
The usual faucet hole size is about 1 3/8 inches in diameter. This size fits many faucets for both kitchen and bathroom sinks. But, some faucets need a hole that's 1 1/2 inches in diameter. Always check your faucet's specs to make sure it fits your sink's hole size.

While there are standard sizes for sink plugs, it's essential to measure your sink accurately to choose the right size. Whether you have a kitchen sink or a bathroom vanity, understanding sink plug sizes can save you from common issues like leaks.
If you have the old plug it should have the size embosssed on the top surface. This is usually imperial, so 1 1/2 inch or 1 3/4 inch, but it is sometimes missing. You can measure the old plug across its top diameter (in imperial).
Sinks and faucets come in different configurations. The faucet configuration has to line up with the number of holes in the sink. The two components don't necessarily have to match exactly, as extra holes can be hidden with plugs and baseplates.
4-hole sinks allow for a two-handle faucet and a sprayer or soap dispenser. 3-hole sinks allow for two-handle faucets only without accessories. 2-hole sinks allow for a single-hole faucet, and an accessory, like a sprayer. 1-hole sink has no deck plate, and is designed for a single-handle faucet.
If your current mounting setup has more than one hole, measure the distance between the center of the far-left hole to the center of the far-right hole. This is important if you plan to include a deck plate, as you need to make sure that the plate is wide enough to cover the extra holes.
Faucet Connector Sizes
The inlets on a faucet are the components that connect to your water supply lines. Most faucets in the United States have a 1/2" MPT (male) or 1/2" FPT (female) threaded inlet. These connections use the NPT (National Pipe Thread) standard.
NOTE: THIS FAUCET IS DESIGNED TO BE INSTALLED THRU 2 HOLES: A 1-1/2" (38MM) MIN. DIA. HOLE FOR VALVE AND A 1-1/4" (32MM) MIN.
A 1-hole sink accommodates only a single-hole faucet. There is no escutcheon or deck plate. There are no accessories.
For bathroom vanities the standard size is 1 1/2 inch. Manufacturers have also taken into account the old days where sizes were different again, so sink plugs are still available in: 1 inch, 1 1/4 inch, 1 3/8 inch, 1 5/8 inch, 1 7/8 inch, 2 inch, 2 1/4 inch, 2 3/8 inch and 2 1/2 inch sizes.
Bathroom faucets are not universally compatible across all fittings. They come in different mounting types, hole configurations, and sizes. Common types include single-hole, centre-set, and widespread setups.
Measure the Sink Opening
Common Sizes: Most sink drain openings are 1 1/4 inches in diameter, but you might also find sizes like 1 1/2 inches and 1 5/8 inches.
Due to so many different styles, kitchen faucets are not universal. The base plate is often the differentiating factor with some the mounting holes are the standard 1 3/8” but there are also faucets on the market that have a 1 or 1 1/2” mounting hole.
Before purchasing a new faucet, check the spacing on the sink. If there is a three-hole arrangement, determine the spacing by measuring from the center of the handle. Standard spacing is generally four or eight inches. If you prefer a single-hole faucet and the sink has three holes, don't worry.
the simple answer is that basin wastes are 1¼” BSP (32mm), whereas bath and kitchen sink wastes are 1½” BSP (40mm).
Before installing a new kitchen faucet, be sure to go underneath your kitchen sink and check how many holes your existing sink uses. While a one-hole faucet can work in a 2-hole sink, the same won't be true for a 2 or 3-hole faucet in a one-hole sink.
Bathroom taps come in many sizes in terms of the height of the neck and the length of the spout. But most fit into a standard size tap hole (28mm for a bath tap and 22mm for a basin tap). They can sometimes vary, though, so always check before drilling holes.
