Before You Begin

Commencing a task such as replacing your kitchen sink can swiftly become intricate, contingent upon the existing configuration of your sink. One of the more intricate aspects of this process involves aligning the drainpipe and the new sink drain, which may not always be in the same position as they were with the old sink. Anticipate unforeseen circumstances and make arrangements by assessing the dimensions of the sink, capturing photographs (from both above and below the countertop) of the existing installation, and locating a suitable replacement that precisely aligns with the current space and plumbing requirements.

Additionally, ascertain whether you possess a drop-in or undermount sink, the type of countertop you possess (and whether it necessitates cutting to accommodate the installation of the new sink).

What You’ll Need

Measure and Plan

Before the replacement process can start, a few essential examinations and measurements must be completed. This guide will assist you in selecting the appropriate tools and finding the perfect washbasin for your needs.

Start by measuring your current washbasin’s width, depth, and length. Do you happen to know whether this washbasin is under-mount or drop-in? A drop-in sink features a lip that rests above the countertop. The undermount sink is secured beneath the countertop using clips. After determining your current sink’s size and mounting style, you can use this information to select a new kitchen sink.

Hint: Occasionally, it may be feasible to substitute one washbasin style with another. It’s important to consider the material of your countertops. Marble or granite countertops provide a sturdy foundation for under-mount sinks. If you lack a sturdy countertop, opt for a drop-in sink.

Prepare the Area

Replacing a kitchen sink begins with the removal of your current one. Before uninstalling your current washbasin, please follow these steps:

To turn off the water supply, locate the knob underneath the sink and twist it. Once you’ve turned the knob, give the tap a quick test to make sure the water supply is completely shut off.
Please take out the drain trap by positioning an empty bucket below it, right under the sink. The bucket collects any stagnant water in the drain trap. Rotate the slip nuts anticlockwise to loosen them. Take out the drain trap.

Detach the water supply tubes: The underside panel of your sink contains coupling nuts that fasten the water supply tubes to the faucet tailpiece. Use a plumbing wrench to gently loosen the coupling nuts and disconnect the water supply tubes from the current sink. Ensure the bucket remains in position to prevent any potential spills.
Remove any additional fixtures and clips. Certain sinks may have additional plumbing fixtures, such as sprayers or disposals. Please remove those futures from the washbasin.

Remove the Old Sink

With the connections detached and the water supply turned off, it’s time to remove your old washbasin.

Remove clips: If your washbasin has clips holding it in place from below, remove them. This usually only applies to undermount sinks.
Easily cut through caulking: Slice through the caulking around the sink where it meets the countertop using a utility knife or straight edge.
Remove the sink: After detaching the caulking, carefully lift the sink out of its position.

If it’s too heavy to lift, there may be a way to secure the washbasin in place. Be careful to unhook all fixtures. Be careful to verify that the caulk has been cut all the way through.
After removing the sink, gently use a putty knife to scrape away any leftover caulk and debris.
Give the countertops a good wipe. Before placing the new washbasin, ensure the surfaces are well-cleansed with a multipurpose cleanser.

Replace the Fixtures

Before installing the sink, make sure to attach the faucet, straining basket, and disposal. Position the new washbasin on either a countertop or a set of sawhorses. Follow the instructions provided by the manufacturer to install the washbasin features.

For those who may be wondering, a helpful tip for installing kitchen sink drain parts is to use a ring of plumber’s putty underneath the lip to lower the basket into place quickly. Place a gasket around the threaded part of the drain basket underneath the sink. After that, you’ll want to add a washer and a lock nut, securely fastening the lock nut. Lastly, use a dry rag to clean up any excess putty that seeped under the basket’s rim.

Apply Silicone Caulk

Seal your new sink to the countertop by applying silicone caulk. The method may differ slightly depending on how your washbasin is mounted to the countertop.

For a drop-in sink, you’ll want to apply a line of silicone caulk around the countertop opening. Outline the sink opening on the countertop using a smooth, unbroken caulk line. It will follow a similar path to the previous layer of caulk that was removed when you took out your old sink.
For the under-mount sink, apply a line of silicone caulk. There is a rim at the top of the undermount sink to follow.

Pro tip: Ensure a smooth and watertight seal by maintaining a consistent flow of caulk. If you’re new to using caulk, doing a few practice runs on some scrap cardboard might be helpful.

Install a new sink

Now, we can proceed with the washbasin installation. The installation process will differ based on the specific mounting style of your washbasin.

Easy installation: Place the new washbasin into the opening. Apply firm pressure along all the edges. Make sure to remove any excess caulk that may seep out around the edges of the sink before it dries.

Installation: Begin by opening the lower cabinets and carefully manoeuvring the washbasin into position. Enlist a friend’s assistance to support the washbasin from above. Attach the clips firmly to the washbasin and countertop. Start by working around the edges of the sink, using the pilot holes left by your previous sink.

Reconnect Drain and Supply Lines

After positioning and securing the washbasin, reconnect the supply lines. Just head under the sink and reconnect any water supply lines. Make sure to connect the supply to the hand sprayer and drain trap.

Ensure you follow the manufacturer’s instructions for connecting your sink if it has a garbage disposal. The process remains consistent, regardless of the mounting style of your new washbasin.

Turn the Water Back On

Once all the connections are in place, restore the water supply. Give the washbasin a test to make sure everything is working correctly. Inspect the area beneath the washbasin for any signs of leaks or drips and make necessary adjustments to the connection. Make sure to thoroughly inspect all the functions of your washbasin to ensure that the connections are secure and that you can fully utilise all the features it offers. If you encounter any leaks, alterations in water pressure, or drips, it would be advisable to turn off the water supply and double-check the connections.
