How to Measure Kitchen Sink – Comprehensive Guide

Do you need to replace your kitchen sink, or are you just looking to explore more modern designs? No matter your reason, a task that seems quite simple in theory is a complex undertaking in reality – the task of measuring the kitchen sink. A well-kept kitchen is synonymous with a well-maintained home, and investing time in understanding your kitchen sink’s measurements can significantly ease your sink replacement or upgrade process. This article will guide you through the most accurate ways to measure your kitchen sink. Let’s explore how to measure kitchen sink.

How to Measure Kitchen Sink: Step-by-Step Process

Before you begin, it is crucial to have the following measurement tools on hand: a measuring tape, a ruler, possibly graph paper, and a pencil to jot down the measurements. Make sure your tools are clean to avoid staining or damaging the sink area. Now, let’s dive into the step-by-step process of how to measure kitchen sink:

1. Identify the Type of Sink

Kitchen sinks come in different variations – top-mount, under-mount, or the farmhouse style. Top-mount or drop-in sinks have a rim that overhangs the countertop, while under-mount sinks are installed below the level of the countertop. The farmhouse style, also known as apron-front, has the front section exposed and requires a specific kind of cabinet for installation.

2. Measure the Length and the Width

Start by measuring the sink’s length and width – also known as the ‘cut-out’ dimensions used for the countertop opening. For top-mount sinks, measure the length and width of the sink’s inner part present within the countertop boundaries. For under-mount and farmhouse sinks, take the measurements of the entire sink resting against the countertop.

Place the end of your tape measure on the left inner edge and stretch it to the right inner edge to get the length, while for the width, measure from the front inner edge to the back inner edge.

3. Depth, Bowl Partition and Bowl Sizes

The depth measurement is crucial to ensure a comfortable working position and to prevent water splash. For depth, drop your measuring tape from the top of the sink to the bottom of the sink bowl. 

If you have a double-bowl sink, record whether the bowls are equally sized or if one is smaller than the other. Measure the lengths, widths, and depths of both bowls individually.

4. Faucet Hole Spread

Knowing the faucet hole spread is crucial to match the new sink with your current faucet, or if you plan to get a new faucet, this helps you choose the right type. Count the number of holes and measure the distance between them to know the faucet hole spread.

5. Measure from the Front of the Countertop to the Sink

   This measurement ensures that there is enough distance from the front of the countertop to the beginning of the sink for the sink to fit correctly.

6. Drain Position

 Note the Position of the drain, whether it’s right, left, or center-aligned. It helps while choosing your new sink and ensuring it will align with your current plumbing setup.

Remember, while measuring, always double or even triple-check your numbers. The slightest error could result in a sink that doesn’t fit. It’s essential to jot down the measurements accurately.

Replacements and upgrades are relatively simple tasks when you have the correct, accurate measurements to guide you. So, whether you want to install a brand-new sink or replace the old one, this comprehensive guide should simplify the first, albeit essential, step – the process of measuring your kitchen sink. Happy remodelling!
