How To Measure Bathroom Undermount Sink

How to Measure Bathroom Undermount Sink

An undermount sink is a sink that is installed beneath the countertop, creating a seamless look. Undermount sinks are a popular choice for modern and contemporary bathrooms because they are easy to clean and maintain. However, before you can install an undermount sink, you need to make sure that you have the right measurements.

1. Determine the Type of Undermount Sink You Want

There are two main types of undermount sinks: self-rimming and lipped. Self-rimming sinks have a flange that sits on top of the countertop, while lipped sinks have a lip that fits under the countertop. The type of sink you choose will determine how you measure the countertop cutout.

2. Measure the Length and Width of the Countertop Cutout

For a self-rimming sink, measure the length and width of the countertop cutout from the inside edge of the flange. For a lipped sink, measure the length and width of the countertop cutout from the outside edge of the lip.

3. Measure the Depth of the Countertop Cutout

Measure the depth of the countertop cutout from the top of the countertop to the bottom of the cutout. The depth of the cutout will determine how deep the sink will be.

4. Allow for Overhang

When you are measuring the countertop cutout, you need to allow for overhang. Overhang is the amount of countertop that extends beyond the edge of the sink. The amount of overhang you need will depend on the type of sink you choose and the look you want to achieve.

5. Use a Template

The best way to ensure that you have the right measurements for your undermount sink is to use a template. A template is a paper or plastic pattern that you can use to trace the outline of the sink onto the countertop. You can find templates for undermount sinks online or at your local home improvement store.

6. Double Check Your Measurements

Before you cut the countertop, double check your measurements. Make sure that you have the right measurements for the length, width, and depth of the cutout. You should also make sure that you have allowed for enough overhang.

7. Cut the Countertop

Once you are confident that you have the right measurements, you can cut the countertop. Use a sharp utility knife to score the countertop along the outline of the template. Then, use a jigsaw to cut the countertop out.

8. Install the Undermount Sink

Once the countertop is cut, you can install the undermount sink. Follow the manufacturer's instructions for installing the sink. Be sure to use a sealant to prevent water from leaking under the sink.
