The sink faucet requires 1 hole for installation. It can be installed in a hole that has been opened in an inset, undermount, or wall-mounted sink. Additionally, it is tall, so it is suitable for freestanding sinks, meaning it can also be installed on a countertop. 

Depending on the construction, it can be installed behind the sink or on the side. However, you should check that the water flow ends up in the center of the sink, so that it is fully functional. It is a mixer faucet, which means it has only one mixing mechanism to achieve the desired water temperature.
