Converting a Double Sink to Single: A Practical Guide

Are you tired of dealing with the hassle of maintaining a double sink in your kitchen? Converting a Double Sink to Single can bring numerous benefits, including more countertop space, easier cleaning, and improved functionality. In this comprehensive guide, we’ll walk you through the process of converting a double sink to a single sink. Whether you’re a DIY enthusiast or considering hiring a professional, we’ve got you covered with all the information you need.

Benefits of Converting a Double Sink to Single

1. Increased Countertop Space

One of the primary advantages of switching to a single sink is the additional countertop space it provides. With a double sink, the center divider takes up valuable area that could be used for food preparation, placing large pots or pans, or simply having more room to work. By opting for a single sink, you can maximize your countertop space and enjoy a more spacious and functional kitchen.

2. Easy Cleaning and Maintenance

Cleaning a double sink can be a time-consuming and tedious task. The two basins and the divider in between often accumulate dirt, grime, and water stains, requiring extra effort to keep them clean. With a single sink, you eliminate the hassle of cleaning two separate basins and dealing with the hard-to-reach areas. It’s much simpler to maintain a single sink, saving you time and energy in your daily cleaning routine.

3. Enhanced Functionality

A single sink offers enhanced functionality compared to a double sink. It allows you to easily wash larger items such as baking sheets and oversized pots that may not fit comfortably in each basin of a double sink. Moreover, a single sink provides flexibility in terms of installing various faucet styles, including pull-down or commercial-grade faucets, which may not fit well in a double sink setup. By converting to a single sink, you can enjoy a more versatile and efficient kitchen space.

Steps to Converting a Double Sink to Single

Now that you understand the benefits, let’s dive into the step-by-step process of converting your double sink to a single sink.

1. Plan and Prepare

Before starting any project, it’s crucial to plan and prepare adequately. Measure your current double sink and the cabinet space available to ensure a single sink will fit properly. Take note of the existing plumbing connections and determine if any modifications will be necessary.

2. Gather the Tools and Materials

To successfully complete the conversion, gather the necessary tools and materials. This may include a wrench, pliers, pipe cutter, plumber’s putty, silicone caulk, and a new single sink that matches your kitchen’s style and dimensions.

3. Shut Off the Water Supply

Locate the water shut-off valves under the sink and turn them off to prevent any water flow during the installation process. It’s essential to shut off both the hot and cold water supplies.

4. Disconnect the Plumbing Connections

Using the appropriate tools, carefully disconnect the plumbing connections from the existing double sink. This includes disconnecting the drain pipes, water supply lines, and any additional connections such as a garbage disposal unit or dishwasher.

5. Remove the Double Sink

Once the plumbing connections are disconnected, remove the double sink from the countertop. This may involve unscrewing mounting clips or brackets that secure the sink in place. Be cautious while removing the sink to avoid damaging the surrounding countertops or cabinets.

6. Install the Single Sink

Position the new single sink in the desired location on the countertop. Ensure it aligns properly with the existing plumbing connections and mark any additional holes that may be required for the faucet or accessories.

7. Connect the Plumbing

Reconnect the plumbing connections to the new single sink. Use plumber’s putty or silicone caulk to create a watertight seal around the drain opening. Connect the water supply lines and ensure all connections are secure.

8. Test for Leaks

Once the plumbing connections are reconnected, turn on the water supply and check for any leaks. Run water in the sink and inspect all connections, including the drain, faucet, and water supply lines. If any leaks are detected, tighten the connections or apply additional sealant as needed.

9. Finalize the Installation

After confirming that there are no leaks, clean the sink and surrounding area. Ensure the sink is properly secured to the countertop and make any necessary adjustments. Reinstall any additional accessories such as a garbage disposal unit or dishwasher if applicable.

Congratulations! You have successfully converted your double sink to a single sink, enjoying the benefits of a more spacious and functional kitchen.


Converting a Double Sink to Single can significantly improve the functionality and aesthetics of your kitchen. With increased countertop space, easier cleaning, and enhanced versatility, a single sink offers numerous advantages. By following the step-by-step process outlined in this guide, you can successfully complete the conversion either as a DIY project or with the help of a professional.
