When it’s time to update your kitchen sink, it’s important to make sure the new sink you choose fits into your counter and cabinet space. Learning how to measure a countertop for a sink is easy and can be done in just a few steps. This guide will teach you how to measure a kitchen sink to ensure the perfect fit.
When learning how to measure a kitchen sink for replacement, first you need to know what type of sink you currently have. There are three main types of sinks: undermount sinks, drop-in sinks and farmhouse sinks.
Once you know your type of sink, prepare to take kitchen sink measurements by following these steps:
Make sure your sink is clear of dishes and clean. Takeall measurements twice, just to ensure your measurements are accurate. Install will vary depending on sink type and measurement directions may be slightly different.
When learning how to measure kitchen sink size, you may need to make some adjustments for your type of sink.Below we cover standard kitchen sink measurements, plus tips for how to measure undermount kitchen sinks and farmhouse kitchen sinks.
Measure the length of your sink by placing the edge of your tape measure on the left edge of the sink and stretching it across to the right edge. Write down the length. Lastly, measure the basin depth. Place your straightedge ruler or your level across the top of your sink. Use your tape measure to measure the deepest part of your sink basin to the bottom edge of the ruler. Write down the depth. If you have an undermount sink, be sure to measure the height from sink to countertop. If you have a farmhouse sink, also measure the depth from the top edge to the bottom edge of the exposed front, in case these depth measurements differ.
Now that you have your kitchen sink measurements, measure your cabinet space.When replacing a sink, it’s important that your new kitchen sink be the same bowl size (sink width and sink depth) of your current sink. Otherwise, you may have to replace your cabinet too. The sink cabinet measurements are going to determineexactly what size sink you can install.
Start by measuring the depth of your cabinet. Place your tape measure along the bottom of the cabinet and measure from the back to the front edge. Next, measure the total width. Place your tape measure along the bottom of the cabinet to measure from the left edge to the right edge. Now that you have a total number, subtract approximately 4-inches from the overall width and 1-inch from the depth to get your sink width. If you have a drop-in sink, be sure to measure the interior width of the sink top at the widest spot and then subtract the same 4-inches. If you are replacing a farmhouse sink, measure the height of the exposed front of your old sink. This will be the maximum depth of your new sink. If you are installing a farmhouse sink for the first time, you will have to remove the false cabinet drawers for installation. Measure from the top of the counter to the top edge of the cabinet door. Subtract at least 1-inch from this measurement for buffer space. This will be the maximum depth of your new sink.
Tip: The most common size for standard sink base cabinets is typically 24-inches from back to front.
You will need to remove your old sink to take this set of measurements. When doing so, be sure to shut off water valves that lead to the sink, disconnect the water lines and remove the faucet. Then disconnect the drain attachments and remove the sink.
With your old sink removed, measure the area just as you did in step 1. First, measure from side to side and then back to front. This is the total width available for your new sink. It”s important to pay attention to your corner ratio. Be sure the corner radius and the lip of your new kitchen sink are not smaller so that all gaps are covered. For an undermount sink, the cutout should match the new sink’s interior measurements. For a drop-in sink, keep in mind how much overlap you will need between the lip and the counter.
Use all three methods to measure your sink to ensure you have the most accurate measurements. Now that you know how to measure a kitchen sink,you can find a new sink that’s a perfect fit.
