If the sink you’ve chosen has a faucet hole integrated into it, it may come with a faucet. You don’t have to choose to use this faucet if you like another one better, but there are a few things you’ll want to consider. Look at the faucet hole, and you’ll be able to determine if it’s proprietary to the faucet that comes with the sink. If it is, you’ll be stuck with that faucet, so you may want to consider another sink.
If the hole doesn’t have an odd, proprietary shape, you can choose a sink-mounted faucet, and you’ll be on your way. Because of the placement, you shouldn’t have to worry about any special plumbing problems, and you should be able to continue with installation.
