How to Measure a Kitchen Sink & the Countertop Hole?

An old and worn-out sink never looks good in a kitchen. It indicates that you need to replace it with a new one. If you are considering buying a new one, you need to know the measurements first.

It brings me to the question, how to measure a kitchen sink?

Remove the old kitchen sink first and take measurements of the width and length of the countertop hole. Then, get a new kitchen sink that fits that hole. You also can measure without removing the sink, but the measurements will not be 100% accurate.

Today, I will explain both measurement processes. First, let me show you how to measure the sink without removing it and then how to measure the countertop hole. Keep scrolling to find out the details.

Things you will need

Before you begin measuring the kitchen sink, ensure you have the following tools and materials ready:

  • Measure tape
  • Paper
  • Pencil/Pen
  • Flashlight

Once the items are ready, follow the guides below and start measuring the kitchen sink.

How Do You Measure a Kitchen Sink?

Whenever you decide to replace the old sink in your kitchen, you will need accurate measurements. If you take the wrong measurements, the sink will not fit.

But do not worry. Measuring a kitchen sink is simpler than you think only if you follow the guide in this article.

Here is a step-by-step guide on how to measure a kitchen sink:

Step 1: Clean the area and gather the tools

Before starting, gather all the necessary tools and clear the sink area. If there are excess items or obstructions around the sink, it may lead to long measurements.

Hence, clean the area and follow the next step.

Step 2: Measure the sink width

Now, start by measuring the kitchen sink’s width. Place the beginning of the measurement tape on the left side of the outer rim. Measure it to the opposite of the right side.

Then, measure the width of the sink for the inner side. Hold the tape at one side of the inner rim and then hold the other end to the other inner rim of the opposite end.

Write down the measurements on a paper.

Step 3: Measure sink length

Now, move on to measuring the length of the sink. Similar to how you measure the width, take measurements for both the inner and outer rim.

Step 4: Measure sink depth

Next, measure the sink’s depth. Place the tape to the highest point of the inside of the sink. Stretch it to the lowest point of the sink and write down the measurements.

Step 5: Double-check the measurements

Lastly, recheck all your measurements. That is because if you take the wrong measurements and bring a sink from the market, you will need to go back and change the sink.

How to Measure the Countertop Hole for a Kitchen Sink?

Measuring the sink is useful when you want a similar-sized sink or do not want to go into the hassle of taking out the sink and measuring the hole.

But as you will eventually take out the kitchen sink, it is better to first remove it and take the measure of the countertop hole. Then, you can select any new sink that will fit that hole.

Here is the step-by-step guide on how to measure the countertop hole for a kitchen sink:

Step 1: Remove the sink

First, remove the installed sink from the kitchen countertop. Don’t forget to turn off the water supply to the sink.

If you do not have enough experience about how to remove a kitchen sink, you may get help from your friend or call a plumber.

Step 2: Measure the hole width

Now, take the measurements tape and start with measuring the hole width. Place one end of the tape on the widest side and extend it to the other end.

Step 3: Measure the length

Similarly, take the measurements for the length of the countertop hole. Take notes for both the measurements and then take it to the store where you buy the sink.

Measuring Faucets and Drain Holes

However, if you only plan to replace the faucets or the drain pipes, you will only need to measure the holes. Then you can buy the faucet and pipe and replace them.

First, remove the old faucet from the kitchen sink. Then, take the tape and measure the diameter. Also, note the shape of the hole. Most of them are round, but some can be rectangular too.

You can measure the drain hole of the sink in the same way. It is important to note that some of the kitchen sink faucets have extra features, which means there can be extra holes. In that case, it is better to take photos and show them to the shop owner to ensure you buy the right faucet.
