What type of faucet is referred to as a "Center set" faucet?

A "Center set" faucet is a type of faucet design that combines the spout and handles into a single unit. Typically, this configuration includes a spout that is centrally located with two handles on either side, all mounted onto a single base. This design is popular for its compact size and ease of installation, particularly in smaller bathroom sink areas.

Center set faucets are often designed for three-hole installations—two holes for the handles and one for the spout, all at a distance that fits within the standard spacing for this type of faucet. This sets them apart from other configurations, such as widespread faucets, which have separate components that can be spaced further apart. Understanding the differences between these configurations helps when selecting the right faucet for a specific installation needs.
