Components of a Bathroom Sink Faucet Diagram

The components of a bathroom sink faucet diagram can vary depending on the type of faucet you have. The most common components are the spout, handle, escutcheon, cartridge, aerator, and supply lines. Each component has its own purpose and knowing what it does will help you in your DIY plumbing projects.

Spout: The spout is the visible part of the faucet that extends from the base. It is connected to the handle by a stem and can come in different shapes such as straight or curved. The purpose of the spout is to direct water from the supply lines into your sink or basin.

Handle: The handle is used to turn on or off the flow of water from the spout. It usually consists of two separate pieces which are held together with screws or nuts. Turning one way will turn on the water while turning it the other way will turn it off.

Escutcheon: The escutcheon is an optional piece that covers up any exposed piping from underneath your sink. It also helps to protect your wall from any damage caused by water leaking from your sink or taps.

Cartridge: The cartridge is an internal part that controls the flow of water from your faucet handle. It contains seals and valves that help regulate the pressure and temperature of your water flow.

Aerator: An aerator is a small device attached to the end of your spout which helps reduce splashing while also reducing water consumption. This device works by breaking up large droplets into much smaller droplets which results in less splashing and less wastefulness when using your taps.

Supply Lines: Supply lines are pipes that run underneath your sink which deliver water from your main supply line to your taps and fixtures. They usually come in two sizes; ½ inch for cold water supply lines and ¾ inch for hot water supply lines.

Types of Sink Faucets

There are several different types of sink faucets available in today’s market, each designed with its own unique features and benefits. The most popular types include pull-down, pull-out, single lever, two-handle, wall mounted, bridge style, pot filler, bar prep faucets, laundry tubs, and widespread faucets among others.

 Pull-Down Faucets: Pull-down faucets are one of the most popular types due to their convenience and ease-of-use. They have a spray head which can be pulled out from its base so that it can reach any area within reachable distance around your sink basin. They are also easy to install since they only require one hole in your countertop for installation purposes.


 Pull-Out Faucets: Pull-out faucets offer more flexibility than pull-down models due to their extendable hose feature which allows them to reach further distances such as over tall pots or pans in order to fill them with water or rinse dishes etcetera without having to move them around manually as you would with a pull-down model.


 Single Lever Faucets: Single lever faucets are very common and easy to use since all you need to do is move one lever up or down in order to control both temperature and flow rate settings simultaneously without having to adjust multiple knobs at once like with two-handle models for example.


 Two Handle Faucets: Two handle faucets are designed with separate valves for controlling both temperature settings (hot And cold) and flow rate settings (low and high). Although they are a bit more complicated to install and use, they offer more precise temperature control as you can adjust each valve separately for exact temperature settings.
