In the context of
bathroom faucets, "Centerset" refers to a specific type of faucet configuration. A Centerset faucet typically consists of a single unit with both the handles and the spout mounted on a base that measures 4 inches from the center of one handle to the center of the other. It is a common and convenient option for bathroom sinks with three holes, where the outer holes are used for the handles and the center hole for the spout.
