How to Install Sink Mounted on Top of Countertop
Installing a countertop sink is typically done when a new counter is being installed in a kitchen or in a bathroom. Most countertop sinks are self-rimming and have a drop-in bowl that is inserted into a hole that has been cut out of the top of the counter. Proper measurements will be needed before cutting a hole in the counter for the sink. You can install a countertop sink by first making sure the sink location is correct. Does this Spark an idea?

Measure the length and width of the countertop with a tape measure to determine where the sink is going to set. Make sure the sink is centered from front to back and side to side.

Draw an outline for the sink on the countertop with a pencil. You can use a template, if one is included with the sink. Place the template on the counter and trace around it with a pencil. Alternatively, you can place the sink upside down on the counter and trace around it with a pencil. You will then need to draw another line ½ inch inside the first outline line for the actual cut line.

Tips & Warnings
Drop-in sinks are the easiest type of sink to install in a counter.
Tracing around the sink and cutting the outline without making a smaller outline on the inside will leave you with a hole in the counter that is too big for the sink.
