Fit the new sink

What you need to do:

  • Measure the opening in the countertop to make sure the new sink will fit.

  • If the sink is undermounted, you will need to drill holes in the countertop for the clips or brackets.

  • Apply plumber’s putty around the edge of the sink.

  • Carefully lower the sink into the opening in the countertop.

  • Secure the sink to the countertop using the appropriate clips or brackets.

  • If the sink is undermounted, tighten the clips or brackets until the sink is secure.

How to do it:

  • Measure the opening in the countertop and compare it to the measurements of the new sink.

  • If the opening is too small, you may need to resize it.

  • If the opening is too large, you may need to shim the sink to make it fit.

  • Apply plumber’s putty around the edge of the sink.

  • Carefully lift the sink and lower it into the opening in the countertop.

  • If the sink is undermounted, use a wrench to tighten the clips or brackets until the sink is secure.

Tips:

  • Take your time and make sure the sink is level.

  • If the sink is not level, it will not drain properly.

  • Use plumber’s putty to seal the gap between the sink and the countertop.

  • This will help to prevent leaks.

Connect the plumbing

  • Connect the hot and cold water lines to the new sink.

  • Connect the drain line to the new sink.

  • Attach the dishwasher hose to the new sink.

How to do it:

Your burning questions :

Can I install a kitchen sink myself?

Yes, it is entirely possible to install a kitchen sink yourself, provided you have the appropriate tools and a basic understanding of plumbing. However, if you’re not comfortable with DIY projects or lack plumbing experience, it’s advised to hire a professional. Always remember, incorrect installation can lead to leaks and water damage.

Do you need a plumber to fit a kitchen sink?

While it’s possible for a skilled DIY enthusiast to fit a kitchen sink, hiring a professional plumber is highly recommended. Plumbers have the necessary skills and tools to ensure a proper and secure installation. Furthermore, they can troubleshoot any potential issues and ensure the work complies with local plumbing codes.

Does silicone hold sink in place?

Yes, silicone is often used to hold a sink in place. Primarily, it serves as a waterproof sealant with adhesive properties, preventing any leakage around the sink area. It is applied between the sink and the countertop to ensure a tight, secure fit, thereby adding stability to the installed sink.

What can I use to secure my sink to my countertop?

You can use a variety of tools to secure your sink to your countertop. The most common method is by using sink clips or mounting brackets, which come with most sinks. However, you can also use a silicone adhesive or caulk, along with plumber’s putty, to ensure a secure, immovable, and watertight fit.

What is the easiest kitchen sink to install?

The easiest kitchen sink to install is the drop-in or top-mount sink. This type of sink simply ‘drops-in’ to a hole cut out in the countertop and is sealed around the edges. No special mounting is required as the weight of the sink, along with the sealant, holds it in place.
