How to Buy the Right Size Kitchen Sink

by Staff Writer

Whether buying a kitchen sink for the first time or as a replacement for your old kitchen sink, you probably have some questions about what size of kitchen sink you need. This article will help you choose the right size sink for your kitchen. The major things to consider are the depth, the shape, the available countertop space and if your countertop already has a cutout or needs one to be made. You will also want to consider the size of your kitchen. A cozy kitchen will look and function better with a size-appropriate sink as opposed to a jumbo triple-basin sink. On the flip side, large kitchens can accommodate larger sinks.

  • Kitchen size matters.

    As a general rule of thumb, if your kitchen measures 150 square feet or less, a 22-inch by 24-inch standard single-bowl sink will fit your kitchen nicely. Larger kitchens will do well with multi-bowl sinks.

  • Measure the cabinet size.

    Every kitchen sink has a minimum cabinet size. A minimum cabinet size is the measurement of your countertop and under-sink cabinet. The average cabinet size is 24 inches from front to back. To figure out the cabinet size, measure the area where the new sink will be placed. Measure the area right to left from edge to edge, allowing 2 or 3 inches on each side for mounting.

  • Decide on the shape.

    The shape of a sink can determine where the sink should be installed. Corner sinks are an example of this.

  • Choose the basin or bowl.

    Decide whether the sink will be a single basin, multi basin or bowl, and then determine the size of each. This will help to determine the space needed under the counter for installation, as well as how a disposal will be installed if preferred.

  • Consider how it will be mounted.

    The different mounting options are overmount or self-rimming, undermount and seamless or integral. Each type of mount will be installed differently which can cause a slight variance in the space needed for the sink.

  • Think about a backsplash.

    If there's a backsplash, the average is 1/4 to 1 1/4 inches thick, which can decrease the space available for your sink. If there's not a backsplash already added, consider tiling the wall behind the sink. Tiling the wall will help keep the maximum space available for installing the sink.

  • Keep in mind the tasks the sink will be used for.

    Ask yourself what types of tasks you need your kitchen sink to be able to handle. A deep basin sink is great for large pots and pans while a small basin, also known as a prep sink, is good for washing and peeling produce. Sometimes there may be a mixture of tasks done in the same sink or multiple people using the sink at once. There are many different sizes and configurations of sinks available to suit both you and your kitchen.
