How to Measure for Undermount Sinks

Measure for an undermount sink.

Undermount sinks mount under a countertop so that the counter completely covers all sides and edges of the sink. These sinks are dissimilar to traditional sinks in which the the sink edges are visible over the countertop. Undermount sinks are stylish and attractive, and if you measure and install them properly, they seldom leak. The best way to measure for an undermount sink is to use the template that comes with the sink. If you don't have a template, however, you can still measure using the actual sink as a template.

Things You'll Need

• Tape measure
• Marker

Instructions

1. Turn your new undermount sink upside down on the countertop where you will install it. You will use the actual sink as a template to measure where to make your cuts in the countertop. Draw a line with a marker all the way around the sink.

2. Measure from the rim of the undermount sink to the place you'd like for the undermount sink to begin. You can let the countertop hang over the sink or be flush with the sink.

3. Draw a line inside the measurement of Step 1 with the measurement you took in Step 2.

4. Cut out around the measurement from Step 3 to place your undermount sink.

Tips & Warnings

• If a template is included with your undermount sink, use the template to mark your cut lines for the undermount sink.

• Install the sink far enough toward the edge of the countertop to leave room to install faucets and a backsplash behind the sink.

• Double-check your measurements before cutting.
