The Germany sink faucet needs 1 hole for its installation. It can be placed in a hole that has been opened in an insert, substitute or hanging sink. In addition, it is high, so it is suitable for free-standing sinks, ie seated ones, since it can also be placed on a counter. Depending on the construction, it can be placed behind the sink or on the side. However, you should check that the water flow ends in the center of the sink, so that it is fully functional.
