Many sinks come predrilled with mounting holes to accommodate accessories or faucets. When you are looking for a replacement faucet, there are two options. One, you can choose anything you want as long as it matches the number of holes in your sink. Two, you can either select an undermount or drop in sink without holes. Then again, your countertop will need to match what your faucet requires. If you're replacing a faucet that is already installed, it is important to match up the mounting mechanism. The faucet may come with a base or deckplate that can cover up any holes that aren't being used. A faucet with more than one sinkhole should not be purchased. Drilling holes into sinks is tedious and not recommended for DIY tasks.
