These days, plenty of people prefer having undermount sinks in their kitchen. But while this cleaner and more minimalist look is easier to maintain; the actual installation can be an issue. Mainly because of the fact that most undermount sinks don’t actually have pre-drilled holes. These sinks go below your countertop, and the accessories like faucets get installed on the space above, directly on your countertop. So, with most models, you won’t need to drill any holes yourself — you simply install the faucet separately.
