For the most part, homeowners in Phoenix prefer to save wads of cash by installing their own kitchen, bathroom, garage, or laundry room sink. No matter your skill level, it’s not that difficult to do yourself. Even someone with the slightest bit of home improvement experience can accomplish the task by watching a video or two. 

While online media is extremely helpful these days, all you really need is a solid visual aid in front of you that identifies and explains all of the most critical parts to a sink. But before we get into all that, let’s go over some of the types of sinks you can install.

What Kinds of Sinks Are There to Choose From?

When it comes to finding your perfect sink, vanity or fixture, it’s always good to have some sort of design and style in mind. As you’ll notice throughout your search, there are endless varieties of products available. With that in mind, here are some of the most common sinks selected by Arizona homeowners:

This style of sink consists of a double-basin that sits on a counter corner – hence the name. In turn, both of the basins are diagonally set apart from each other. If you’re looking to maximize your counter space, then this might be a good option to settle on. At the same time, corner sinks can be a little more expensive and sometimes present some challenges during installation. Working with a professional may be a good idea.


This type, otherwise known as an apron sink, extends right over the edge of your kitchen counter and comes in either a single or double style bowl. The style tends to suit rustic farmhouse kitchens the best. Because of the renaissance of farmhouse interior design in the Southwest, they’ve been making a comeback in recent years. 

Manufactured with fireclay or cast-iron materials, they’re incredibly durable and easy to clean because of their nonporous makeup. The deep basin, that comes in all kinds of shapes and sizes, makes them perfect for huge families with lots of dishes to wash.  Like corner sinks, they can be a bit pricey and a challenge to install for the first time. 


The durable metal design of stainless steel sinks makes them incredibly light and easy to install. Aside from this, they’re mostly popular because of their excellent stain and heat resistance. No matter the design, they’re classified by sheeting thickness or gauge. Thinner gauges mean the sink is more lightweight, but the strength of the molding adds to the price tag. Thicker gauges are cheaper but heavier.

The Four Parts of a Sink You Ought to Know.

If you’re looking to install a sink yourself or simply get in the know as a new homeowner, here’s a quick overview of common sink parts and their various functions: 

1. Quality Water Supply Lines Are Essential.

When it comes to installing a functional sink, nothing is more important than the water supply. In other words, if you don’t have quality water lines, you don’t have a working sink. Hot and cold water lines connect the sink to your home’s drain plumbing and send water from the main to where it’s intended to be used.  

If you’re replacing your sink then it’s probably a good idea to replace your water lines. It won’t increase your expenses by much. They come in various lengths and tend to be either braided steel or braided steel with a PVC coating. After installing your hot and cold water lines, make sure you turn on both temperature valves to check for leaks. The remaining critical parts to a sink aren’t nearly as important.

2. You Need Faucet Fixtures and Handles.

If your faucet is in rough shape because of wear and tear, damage or leaking seals, it might be time to find a replacement part. While it may be tempting to purchase the cheapest brand model on the market, try to choose something that will last. Cheap plumbing materials, mixed with hard Arizona water, always seem to fall apart quickly

When making your selection, it’s important to understand the benefits and features of different faucets. Some have a single handle while others come with two. Some come with accessories and others don’t (Ie: Faucet sprayers and soap dispensers). 

When replacing the faucet, look underneath the sink to see how many holes it has. Usually, this number is between one and four, helping you determine the type of faucet fixtures that’ll work for your sink. You can install a one-hole faucet in a three- or four-hole sink by adding a deck plate. However, you can’t do it the other way around. If you have any questions, feel free to give one of our plumbers a call.

3. Effectively Sealed Drains Are Important.

When replacing a sink, it’s also a common practice for homeowners to switch out the old drain assembly line. At the same time, the process of installation will depend on how many changes are being made to the sink. 

If the new one is a lot different than the old, or additional components are being installed, the complexity of the project will increase. For example, your new sink may have a divergent depth in comparison to the former model. If so, you’ll probably have to change the drainpipe fitting that enters the wall.

Testing Your Drains is Also a Critical Step.

Similar to water lines, you should always check for leaks after running your new drains. You can do so at each pipe joint by tightening those that feel loose. Conduct a final test by filling up each sink basin and letting it drain while checking for leaks below.  

Keep in mind, it’s not unusual to experience some leaking from slip nut joints. Usually, all it takes is a slight adjustment. If initial tightening doesn’t stop the leak, back out the nut, reposition the washer, and re-tighten the nut to make sure it’s not cross-threaded

4. Sturdy and Functional Basins Protect Pipes.

In a nutshell, the basin is the main part of the sink. In most Phoenix homes, it’s an open-top container that holds water from a faucet before emptying into a drain. Sink basins can be installed on a countertop, legs, pedestal, or even mounted on the wall. 

Like the other critical parts to a sink, basins come in a number of sizes and shapes. They’re also available in various materials, including stainless steel, cast iron, copper, porcelain, and glass. There are advantages and disadvantages to each material.

Each style or build comes with its own set of benefits and drawbacks. For example, cast iron basins are heavy but durable and come in a stunning array of colors. A glass basin may be aesthetically pleasing, but you’ll need a special, non-abrasive solution to keep it clean. Whatever your preference is, there’s certainly a style of sink for you!

Now You're Ready to Install Your Sink!

So, there you have it—a quick overview of the most critical parts to a sink. Now that you know the various functions of this plumbing system, and what you should keep in mind when installing one, you should have a good place to start. 

Look, a sink is not that difficult to install if you have a little know-how. In fact, it can be rewarding to kick back after your hard work and enjoy the exquisite satisfaction of doing the job yourself.

Back in 1883, Warren Johnson invented an electrical thermostat to control the indoor temperatures during the winter. The only problem was, it simply signaled janitors to produce more heat for himself. A few years later, Albert Butz created a pulley system to open and close the furnace door. But neither are anything close to the smart thermostats that are available today.
