How to Measure a Bathroom Sink

Whether you are installing a new sink or purchasing a new sink, measuring your existing sink is a crucial step. Regardless of whether you purchase a new sink or not, understanding the measurements of your existing space will save you a great deal of hassle and is key to remodeling your existing bath space. 

Why would you need to measure a sink?

Measuring your sink is an important step as it allows you to understand what size sink can fit into your existing space. Regardless of what material or sink style you want, your sink measurements are key to determine what new sink you can install or what repairs can be made to an existing sink. 

• Replacing cracks in your sink- Replacing cracks in your sink will require you to understand the measurements of your sink. To properly secure and reinforce your sink, you will need to know the limits and size of your sink.

• Replacing a faucet or a drain-Knowing the measurements of your sink will allow you to replace additions such as a faucet or a drain more easily. By knowing the measurements of your sink, you can easily pick out the right size faucet and drains that pair with it.

• Installation of a new sink-To install a new sink you will need to understand the measurements and size of your old sink. Sinks can be larger and smaller than your measurements, but you need to have a baseline for what can completely fit into your bathroom space.  
• Ada compliance-Ada compliance or The Americans with Disabilities Act, means that your home needs to accommodate those who are disabled or mobility challenged. Measuring your sink space and your bathroom allows you to understand how much space is available to place your sink at a more accessible height and perhaps put it within easy reach of handlebars.  

What you will need before measuring

Providing an accurate measure of your space will require several tools and a few conditions as well. 

• Clean Surface-A clean sink surface ensures an accurate measurement of the space. If the surface is not clean or smooth, it may provide an uneven height or length measurement, so it is crucial that your surface is clean before it is measured.

• Measuring Tape-A measuring tape is a tool that helps provide an accurate measure of space in both feet and inches.  
• Marker-A marker or ruler is key as it allows you to mark or provide visual indicators before installation so you have a clear idea of where to place your new sink.

Tips for measuring:

Below are some tips for providing an accurate and clear measurement before installing your new sink or bathtub. 

• Cleaning the surface-Cleaning the surface is key to provide an accurate measurement. If the surface is not properly cleaned, you may have an accurate reading.

• If using a pro to assist with installation-Take cautions when using a professional to install your sink or bathtub. Remember that COVID-19 precautions should be observed and that means face masks and proper cleaning precautions. 

• Proper markers-When marking, it is best to use durable markers to retain your markings so they stay legible during installation.

• Measure twice-Measure multiple times to confirm that you have accurate measurements. Measurements may change due to certain variables, so it is best to have numerous measurements so you have a close to accurate approximation.
