Changing kitchen faucets is an important decision and a lot of factors need to be considered especially when you have to replace a faucet from a different company. In the US, standard sizes for kitchen faucets and sink openings are used. For centerset faucets, tap holes are spaced 4 inches apart while for widespread faucets, the distance between hot and cold inlets or mounting hardware is 8 inches. All faucet holes are of a standard size of 1-3/8 inches while some faucets are of 1-1/2 inches. Moreover, usually the size of kitchen cabinets are 36 to 42 inches high and 25-1/4 to 26 inches high. Therefore, in a kitchen cabinet of 36 inches a 22 inches sink will fit. In short the underneath installation is the same for all the kitchen faucets.
When replacing kitchen faucets you need to consider the number of holes in your sink and the distance between the holes. For a 3-hole kitchen sink, the kitchen faucet plate, called a deck plate, covers three holes. For a 4-hole kitchen sink, a 3-hole kitchen faucet is used with an additional hole for a soap dispenser or sprayer. For a 2-hole kitchen sink, which is usually a bar or prep sink, one hole is used for a single-hole kitchen faucet and the other for any additional accessory like a soap dispenser or sprayer. Whereas a single-hole kitchen sink, uses a single-hole kitchen faucet. It does not uses an escutcheon plate or any accessory. Moreover, when replacing kitchen faucets measure the following,
- Overall depth- measure the depth from the lowest point on the sink drain to the sink rim meeting the countertop.
- Overall width- measure from the front to the back of the outermost edges of the sink.
- Overall length- measure from the left to the right of the outermost edges of the sink.
- Faucet size- In case of a double handle faucet, measure the distance between the handle’s center to the faucet center. While for a single handle faucet, measure the distance between the water supply lines placed underneath the faucet.
Usually, faucets these days come with 3/8 inches flex lines already attached to it. In this case, check whether the shutoff valve is 3/8 inches or not. If it is of ½ inches, you will need to replace it with a shutoff valve of 3/8 inches. Also, it is better to replace your shutoff valve with a new one as old ones usually cause trouble. Therefore, you need to know the size of your water pipe and the faucet specifications for them to be compatible.
To sum it all up, replacing your kitchen faucet with another from the same company should not have any fitting issues especially if both the faucet and the sink are made in the USA. Foreign-made (i.e. not made in the USA) faucets or sinks may have fitting issues but it is pretty rare. All you have to decide is whether you want a sprayer on the handle or on the side and single lever or two handle kitchen faucet.
