When it comes to renovating or upgrading your bathroom, measuring the sink size accurately is crucial for ensuring a perfect fit and a seamless installation. Follow our step-by-step guide on how to measure bathroom sink size to avoid costly mistakes and achieve the desired result.

Step 1: Determine Sink Type

Before taking any measurements, identify the type of sink you have or plan to install. Common types include:

• Undermount: Installed beneath the countertop, creating a sleek and modern look.
• Drop-in: Rests on top of the countertop, offering a traditional and versatile option.
• Vessel: Stands independently on the countertop, providing a bold and eye-catching focal point.

Step 2: Measure Length

• Undermount and Drop-in: Measure the inside length of the sink, from left to right.
• Vessel: Measure the outside length, including the rim or base.

Step 3: Measure Width

• Undermount and Drop-in: Measure the inside width of the sink, from front to back.
• Vessel: Measure the outside width, including the rim or base.

Step 4: Measure Depth

• Undermount: Measure the vertical distance from the bottom of the sink to the top of the rim.
• Drop-in: Measure the depth of the sink bowl, from the top of the rim to the bottom.
• Vessel: Not applicable.

Step 5: Measure Faucet Holes

• Undermount and Drop-in: Measure the distance between the faucet holes, center to center.
• Vessel: Not applicable.

Step 6: Measure Cabinet Size

If you’re replacing a sink in an existing cabinet, it’s essential to measure the cabinet size to ensure the new sink will fit properly.

• Undermount: Measure the inside width and depth of the cabinet.
• Drop-in: Measure the outside width and depth of the countertop opening.

Step 7: Measure Plumbing Connections

Take note of the location and type of plumbing connections for the sink. This information will help you determine the compatibility of the new sink with your existing plumbing system.

Tips for Accurate Measurements

• Use a measuring tape specifically designed for home improvement projects.
• Measure to the nearest 1/8 inch for precision.
• If possible, remove the existing sink to get the most accurate measurements.
• Consider the thickness of the countertop and backsplash when measuring for an undermount sink.
• Check the manufacturer’s specifications for any specific measurement requirements.
