If you’re planning to remodel your kitchen, one of the essential elements that you need to consider is the sink. It’s where you wash your dishes, prepare food, and sometimes even bathe your pets! However, when it comes to installing a new kitchen sink, many homeowners wonder if they should call a plumber or handle the installation themselves.

In this blog post, we’ll answer the question: do plumbers install kitchen sinks? We’ll explore why it’s important to hire a professional for this task and what factors you should consider before making a decision. So let’s dive in!

What's Inside

Types of Kitchen Sinks Plumbers Install

Types of Kitchen Sinks Plumbers Install

When it comes to kitchen sinks, there are various types available in the market. Plumbers can install any type of sink that you choose, but it’s essential to select one that suits your needs and preferences.

Some popular options include undermount sinks, top-mount or drop-in sinks, farmhouse or apron-front sinks, and integrated or seamless sink designs.

Undermount Sinks: These are installed underneath the countertop for a sleek look and easy cleaning.

Top-Mount Sinks: Also known as drop-in sinks because they sit on top of the counter with their edges resting on it.

Farmhouse Sinks: They have an exposed front panel that extends beyond the edge of your countertop for a rustic feel.

Integrated Sink Designs: These offer a seamless look by integrating both sink basin and countertop into one piece without visible seams between them.

Each type has its own unique features and benefits. It’s important to consider factors such as durability, ease of maintenance/cleaning when choosing which type is best suited for your home.

Assessing Plumbing Requirements

This step is crucial because it ensures that the installation process goes smoothly and that you don’t encounter any issues down the line.

Assessing your plumbing requirements involves checking if your current plumbing system can accommodate the new sink’s size and configuration. For instance, if you’re planning to install a double-bowl sink instead of a single bowl one, you need to ensure that there are enough drain lines available for both bowls.

Another factor to consider is whether or not additional water supply lines are needed for features such as sprayers or soap dispensers. If so, then these will need to be installed before proceeding with the actual sink installation.

It’s also important to check if there are any leaks in your existing pipes or fixtures before starting work on installing a new kitchen sink. A professional plumber can help identify potential problems and provide solutions before they become bigger issues.

Measuring and Cutting the Countertop


This step is crucial to ensure that your sink fits perfectly into the space provided. If you’re not confident in your measuring skills or don’t have experience cutting countertops, it’s best to leave this task to a professional plumber.

However, if you decide to take on this task yourself, make sure that you have all of the necessary tools and materials before starting. You’ll need a tape measure, pencil or marker for marking measurements on the countertop surface, a jigsaw with an appropriate blade for cutting through stone or laminate surfaces (if applicable), clamps for securing pieces together while cutting them out from larger sheets of material like granite slabs.

It’s important also not only consider how much space is needed around each side but also account for any additional features such as garbage disposals or soap dispensers which may require extra clearance underneath where they will be installed later down line during plumbing installation process by professionals like plumbers.

Preparing the Workspace

This step is crucial in ensuring that the installation process goes smoothly and without any hiccups. First, clear out all items from under your existing sink and remove any clutter around the area where you’ll be working.

Next, turn off both hot and cold water supply valves located beneath your sink or at the main shutoff valve if there isn’t one under your sink.

Once you’ve turned off the water supply valves, disconnect all plumbing fixtures attached to your old kitchen sink carefully. Be sure to have a bucket handy as some residual water may still be present in pipes or traps.

After removing everything from underneath of old sinks such as garbage disposals or dishwasher connections (if applicable), use a wrench to loosen nuts holding down mounting clips on top of countertop surface surrounding current fixture location.

Removing the Old Kitchen Sink

This task can be challenging and time-consuming, especially if you’re not familiar with plumbing or DIY projects. That’s why hiring a professional plumber is highly recommended for this step.

When removing an old kitchen sink, plumbers will first turn off the water supply and disconnect all plumbing fixtures connected to the sink. They’ll then loosen any mounting hardware that secures the sink in place and carefully lift it out of its position.

It’s crucial to handle an old kitchen sink with care during removal as it may contain sharp edges or broken parts that could cause injury if mishandled. Plumbers have experience handling these types of situations safely while minimizing damage to your countertops or cabinets.

Once removed, plumbers will inspect your existing plumbing system for any signs of wear or damage before proceeding with installation of your new kitchen sink.

Installing the New Kitchen Sink

This is where a plumber’s expertise comes in handy. Plumbers are trained to handle different types of kitchen sinks and can ensure that your new sink is installed correctly.

The first step in installing a new kitchen sink is to position it on top of the countertop and trace its outline with a pencil. Next, use a jigsaw or handsaw to cut along the traced line carefully.

Make sure that you measure accurately before cutting as any mistakes could result in an ill-fitting sink.

After cutting out space for your new kitchen sink, place it into position and secure it using clips or mounting hardware provided by the manufacturer. Ensure that everything lines up correctly before tightening all screws securely.

Connect plumbing fixtures such as faucets and drains according to manufacturer instructions while ensuring there are no leaks present after installation.

Connecting Plumbing Fixtures

This step requires a bit of technical know-how and experience, which is why hiring a professional plumber can be beneficial. A licensed plumber will have the necessary tools and expertise to ensure that all connections are secure and leak-free.

The first fixture that needs to be connected is usually the drain assembly. The drain assembly consists of several parts, including a tailpiece, P-trap, extension pipe or tubing (if needed), and strainer basket or stopper.

These components work together to prevent clogs by directing wastewater out of your home’s plumbing system.

Next up are water supply lines for hot and cold water faucets. Plumbers use flexible hoses made from braided stainless steel or reinforced polymer materials for this purpose as they offer durability while being easy to install.

Finally comes testing everything out! Once all fixtures have been connected correctly with no leaks detected during installation process; turn on both hot & cold taps simultaneously so you can check if there’s any leakage around joints between pipes/fittings before using your new kitchen sink regularly.

Securing the Sink and Checking for Leaks

This step involves attaching clips or brackets underneath the countertop to hold the sink firmly in place. The plumber will use a silicone sealant around the edges of the sink to prevent water from seeping into any gaps between it and your countertop.

After securing your new kitchen sink, a professional plumber will check for leaks by turning on both hot and cold water faucets at full blast while inspecting all connections for drips or signs of moisture. They’ll also look under your cabinets with a flashlight for any visible leaks that may have gone unnoticed during installation.

Checking for leaks is an essential part of installing a new kitchen sink because even small drips can cause significant damage over time if left unaddressed. A skilled plumber knows how important this step is, so they take their time during this process ensuring everything has been done correctly before leaving you with peace of mind knowing that there are no hidden issues lurking beneath your newly installed kitchen sinks.

Tools and Materials Needed for Sink Installation
