Install a kitchen sink is not as easy as you think. Connecting the sink's drain is the first step. It can swing side to side on two different axes. You need to mark the template of your kitchen sink, if not, apply2-inch tape to outline the sink location. A spade is also an important tool when you have to drill a hole inside the radius. Now, the forth step is cutting along the front and back cut lines. The last step is setting the sink upside down on a padded sawhorse or counter.
