Whether you are looking to repair or replace a sink, it is important to be able to identify the different parts. In some cases, you will find that parts of a sink come packaged together as a kit, while other parts are normally sold individually. Before you tackle that sink project, become more acquainted with the different parts of a sink.

Every sink has the same basic parts.

Sink Basin

The basin is the focal point of the sink.

The sink basin is normally the largest part of the sink, and it is also the most visible. This is the area where the water collects and then drains. Common materials a basin is made of include metal, porcelain or fiberglass in the case of industrial sinks.

Feed Hoses

The water for your sink comes through two hoses.

The feed hoses for your sink attach to two connections at the base of the sink. One connection is for hot water and the other is for cold water. They feed directly to the faucet.


Faucets come in many different designs.

The faucet is what you use to get water into the basin. A faucet will have one output opening but the number of control knobs can vary. There may be a separate control knob for the hot and cold water or there may be one control knob that you use to get the water temperature that you want.


The drain is where the water leaves the basin.

The drain normally comes as a kit. The sink basket gets installed directly into the sink hole in the bottom of the basin. There is an drain pipe that connects to the drain and a locking nut that holds the drain in place.


The p-trap is a pipe that connects the drain pipe in the sink to the drain pipe in the wall. The p-trap is normally sold as a kit that contains the pipe, the washers necessary to prevent leaking and the locking nuts that hold the p-trap in place. The most common materials used for a p-trap are metal, plastic or vinyl.
