Typical design for Standard Faucet Hole Sizes for Kitchens and Bathrooms
Single-hole and Double-hole Faucet
The single-hole faucets are the most common on the market. The single-hole faucets have one hole for a single-hole faucet. Although, some of the sinks have pre-drilled two holes, you can cover the second hole with a escutcheon plate. On the other-hand, the two-hole faucets are designed for having a faucet and the sprayer or soap dispenser and has no escutcheon.
A Centerset faucet has the handles which are usually placed 4-inch apart from the spout. So, there are three holes, combining the spout and two handles on a single base. Sometimes, the faucet has the handles mounted onto a single plate with 6-inches apart.
The Minispread and Centerset are more or less the same. The main difference is, the spout and handles are not connected by a single plate.
Three-hole sink, nowadays, is a common trend. The faucets used on the three-hole sinks have a base plate, or also known as the escutcheon. This escutcheon not only helps to cover the holes but also covers the extra holes when installing a single-hole faucet on a three-hole sink. Furthermore, the spout and handles are six to sixteen inches apart.
The Vessel configuration is only for the tall faucets. The sink in this format is usually higher than for other types. Also, the hole is not drilled into the sink and they come with a single handle.
A Wall-mounted faucet doesn’t attach to the sink as its counterparts but is mounted onto the wall. Normally, they come with long spouts and they must have a good basin clearance.
What to do with the Three- and Four-hole Kitchen Sink
Three-hole sink, nowadays, is a common trend. The faucets used on the three-hole sinks have a base plate, also known as the escutcheon. This escutcheon not only helps to cover the holes but also covers the extra holes when installing a single-hole faucet on a three-hole sink.
A four-hole kitchen sink is the most widely common type of kitchen sink. It is like the three-hole faucet with an extra hole is set a little away for the soap dispenser. A four-hole sink is the most common type of kitchen sink. It is similar to a three-hole design with an extra hole set a little further away for a sprayer or soap dish.
Sink Hole Space Configuration
We recommend to purchase a Center Set or Minispread faucet if the distance between the outer sinkholes on a three-hole sink measures 4 inches. This is because both the single- and two-handle faucets fit in this sink and it is a common bathroom faucet hole size. The pro of this hole size is, you don’t need to modify the sink when installing either type of faucet.
The well-known faucet manufacturer Moen recommends to purchase a widespread faucet if the holes are 6 inches apart or more. Many two-handle and single-handle kitchen faucets are, nowadays, widespread faucets. There are many of the three- and four-hole kitchen sinks which have 6 or 8 inches is a standard sink faucet hole size. The faucets with widespread holes consist of separate parts that are individually spaced without an escutcheon or base plate joining them.
Drilling holes into your sink
Depending on your sink or countertop material, holes can be drilled in a sink to accommodate an odd-sized faucet that does not fit in the pre-drilled holes of your sink. A standard sink faucet holes have a diameter of 1 3/8 inches, but because not all faucets are the same, some will require a 1 1/2-inch hole. It’s also important to check the depth of the sink or countertop before installing a faucet or drilling a hole. If the deck is too thick the faucet may not fit correctly.
Measurements to consider before buying a faucet
Before you buy a faucet, you must measure the distance from the center of the holes to the backsplash and the edge of the sink. Then compare it to the width of the faucet escutcheon, or base, to make sure the faucet will fit. If you are going from a three- or four-hole faucet to a single-hole faucet, many bases will cover holes up to 4 inches apart and some single-hole faucets have bases that will cover up to 8 inches.
