      What You Need To Know About Installing Kitchen Sink Clips

      There are two main types of kitchen sink installation: undermount and overmount. 

      Undermount sinks provide a seamless and attractive installation that looks more expensive. An undermount sink requires a more extensive installation, but it is also more desirable than an overmount sink. 

      Undermount sinks always require kitchen clips, and overmount sinks usually require kitchen clips. In most cases, you will use 10 clips. The clips can attach directly to the lip of the sink or as far as 1” away. 

      There are three types of undermount sink installation:

      • Positive reveal – reveals the sink rim 
      • Zero reveal – perfectly aligned with the opening of the sink
      • Negative reveal – hides the sink rim and overhangs

      Most people prefer zero reveal installation as it looks the best and is the easiest to clean. 

      In order to attach an undermount sink, you need to use kitchen sink clips underneath the sink. The clips keep the sink from moving. The clips also keep the sink from falling to the ground and shattering. The heavier the undermount sink, the more support it requires. 

      After time, kitchen sink clips can become deteriorated, leading the sink to become bent or crooked. When this happens, you may need to replace the clips. 

      An overmount sink may also require kitchen sink clips, depending on the type of sink. Cast iron sinks may not need the clips since the weight will help keep it in place, the opposite of an undermount sink. 

      Be sure to check the building code requirements for kitchen sink installation and take special care to adhere to all regulations and requirements to avoid frustrating and possibly costly changes. 

      Types of Countertops

      A stainless steel sink is typically easier to work with since stainless steel weighs less than most other materials. 

      If you have a granite countertop or quartz countertop, you should be careful that you don’t damage the fragile material when you attach the clamps. 

      In most cases, you will also need a mounting clip for a bathroom sink as well, but that depends on the type of sink you use. 

      Supplies You’ll Need To Install Kitchen Sink Clips

      You will need some basic supplies before getting started. Make sure you have everything you need to ensure you can complete the job as expected. 

      Kitchen Sink Clips 

      Naturally, you’ll need kitchen sink clips. Most are made out of silicone.

      There are two types of kitchen sink clips: attached directly to the decorative rim or attached directly to the sink. Clips that attach to the decorative rim are usually used for overmount sinks, and clips that attach to the sink are usually used for undermount sinks. 

      Silicone Sealant

      A silicone adhesive will allow you to keep the clips and the sink in place while also eliminating the possibility of kitchen sink leaks

      The most common type of silicone sealant is silicone caulk. You can find helpful tips here if you need to recaulk your kitchen sink.

      How To Install Kitchen Sink Clips (5 Steps)

      Now, you need to learn the steps involved in installing kitchen sink clips. Follow these 5 steps to do the job yourself without the help of a plumber.

      Step 1: Remove Sink

      If installing clips on an existing sink, you need to remove the sink from the sink opening in your countertop. 

      You may also need to remove the water supply to the garbage disposal, sprayer, and faucet. This means you will need proper access to the sink cabinet and may need to remove any push fit plumbing fittings used to connect different pipes. 

      If you need to replace any of the lines, keep in mind that supply lines for the kitchen sink measure ½” in diameter. 

      If you have a new sink, ensure that it fits into the sink cutout before proceeding. 

      Step 2: Mark Position of Clips

      With the sink turned upside down, you will mark down the position of the clamps. 

      You want to put an undermount sink clip in each corner and every 10 inches along the side. 

      Step 3: Install Clip

      You will now need to install the clip studs in their position. The clip studs keep the clips in their place. You want the studs facing away from the center of the sink.

      You will use an adhesive to keep the clip studs attached to the sink. Follow the instructions to ensure that the glue dries before moving forward. 

      Once the studs are in place, you will install the screw into the studs using a screwdriver. 

      Step 4: Place Sink 

      At this time, you will place the sink in its proper position. You may need assistance to hold the sink in place at this point. 

      Step 5: Clip Sink to Countertop

      At this time, you will attach the sink to the countertop using the wingnuts that come with the clips. 

      Do not overtighten the clips. You should also be sure to tighten the clips evenly. 

      Final Thoughts on How to Install Kitchen Sink Clips

      You need to attach your sink to your countertop properly. You can do that with kitchen sink clips that fit on the bottom of the sink bowl. You need kitchen sink clips for most sinks. However, it all depends on both the sink and the type of countertop.
