First things first, you should choose between two types of installation:
Deck-mounted kitchen faucets are the most traditional and versatile option, and you'll find models that can match any type of décor style;
Wall-mounted kitchen faucets are an innovative, modern alternative that can help you make the most of smaller countertops that aren't very deep or don't leave you enough room around the sink.
As for the shape of the kitchen faucet, figuring out the one that you like the look of the most will allow you to discard dozens of irrelevant options:
Standard faucets are a space-optimizing and versatile category that relies on a single lever to control the temperature and flow of the water;
Bridge models feature separate handles for hot and cold water, and usually follow more traditional designs;
Although they can sometimes be found as deck-mounted options too, pot filler designs are a modern and minimalist alternative that is particularly popular for wall-mounted faucets: relying on two or more adjustable arms, they can be extended horizontally to reach both sides of a larger double sink or, as the name suggests, to fill a pot on your cooktop.
Don't forget to check the existing holes in your sink! Most have three: two for the hot and cold handle, and one for the spout itself. So, if you're planning on switching from a bridge model to a standard one-lever faucet, you should look for a design that includes a cover plate to hide the other two.
