With these the faucet mounts directly to the countertop and not the sink. If you are installing an undermount sink, you have the option of mounting the faucet directly on the countertop. When installing a deck-mounted faucet, make sure to allow more than a finger’s width behind the faucet for cleaning.

They occupy space on the countertop. Also, you may find an accumulation of water, dirt, and grime between the faucet and the wall.
