Installing a top mount sink into your kitchen may seem like a taunting task, and many people will give you different ideas when comes to how to measure the hole for it to be cut correctly. The fact of the matter is, measuring to install the top mount sink is very easy and can be done in a matter of minutes. Of course, before starting this project, make sure that you have the sink that you plan to install on hand to use as a guide, or better yet, purchase a sink that has a template that you can use.
Tools and Materials You’ll Need:
Step 1: Placement
The first step in this task is to decide exactly where you want the kitchen sink. Measure the length and width of the sink and mark lines onto the counter top. Be sure to leave at least 1 inch from the back wall and the outer edge of the counter top to allow for the width of the lip that is attached on the sink. If you purchase a fancy kitchen sink that has a large rim around the edge, measure the width of it and allow at least that much of a gap around the sink hole. This is simply a rough estimate, so these lines to not have to be perfectly centered or sized.
Step 2: Mark the Outline
Take the sink that you are planning to install, flip it upside down, and place it onto the counter top in the exact area that you want the finished sink to be. Draw a line all the way around the outer edge, taking care to hold the pencil tightly to the edges of the sink.
Step 3: Draw the Inner Line
Measuring to install a top mount sink into your kitchen is a very easy task, and can be accomplished as long as you have a pencil and the sink that you plan to set into place. There is no need to measure the diameter of the sink and then draw lines on the counter for placement. Take the sink off the counter and begin drawing the second line on the inside of the first one. Use a tape measure and go in towards the center of the hole 3/8-inch. Make measurements all the way around the sink in this way, taking extra care that the inner lines match the outer ones perfectly. This is the line that you will have to cut in order to place the sink into the counter. Do not try to freehand the design, or cut along the inside of the outer line in the hopes that the cut will match.
Of course, the easiest way to accomplish this task is to see if the manufacturer of the sink purchased has a template that you can use. If so, simply use the template to draw the outline onto the counter top and cut.
