Too Big or Too Small? How to Measure Kitchen Sink Size Flawlessly
Installing a new kitchen sink can be a frustrating experience if you don't take accurate measurements. Even being off by a fraction of an inch can leave unsightly gaps, misalignments, and drainage problems. Follow this comprehensive guide to measure your existing sink or sink opening precisely for a seamless installation every time.
Taking a few minutes to measure carefully now will save you hours of headaches down the road. Read on to learn the proper techniques for flawless sink sizing.
Measuring an Existing Sink
If your goal is to replace an old sink with a new model, start by measuring the existing sink accurately:
- Use a metal measuring tape to measure across the sink lengthwise from the outer edge of one sink lip to the outer edge of the opposite lip. Note the length.
- For width, measure from the front outer rim straight back to the rear outer rim. The width is the front-to-back size of the sink basin.
- To measure sink depth, use a ruler and measure from the top sink rim down to the very bottom of the basin. Note the depth measurement.
When taking these measurements, account for a few extra inches to allow room for sink accessories like faucets and soap dispensers. For example, measure the length and width 2-3 inches wider than the sink itself to accommodate overhang.
Tips for Measuring Existing Sinks
Here are a few tips to ensure maximum accuracy when measuring your old sink:
- Remove any accessories like faucets or cutting boards before measuring.
- For extra precision, measure twice and take an average.
- Measure the exact sink dimensions, don't estimate or round off.
Measuring for a New Sink
If you're doing a full kitchen remodel and will be installing a sink into a new countertop and cabinet, follow these steps:
- Remove the old sink if possible to expose the original sink opening and cabinet base.
- Measure the countertop opening length and width. Double check for accuracy.
- For depth, measure from the countertop surface down to the cabinet base. Be precise.
If unable to remove the existing sink, carefully measure the overall outer dimensions including any lips or edges. This will approximate the size of the countertop opening.
Regardless of method, be sure to add 2-3 extra inches to the length and width measurements to allow room for faucet spouts, handles, backsplashes, and other overhang.
New Sink Opening Tips
Keep these tips in mind when measuring for a brand new sink:
- Measure twice from multiple angles to verify dimensions.
- Account for rear faucet holes and additional front clearance.
- Consider existing plumbing locations when determining size.
Why Precise Measurements Matter
Being off even a 1/4 inch when measuring for a new sink can lead to:
- Visible gaps between sink and countertop
- Sink not properly centered on countertop
- Inability to hook up plumbing correctly
- Need to re-cut countertop opening
- Leaks, drainage problems due to misfit
Avoid these headaches by carefully following the steps above to get all required sink measurements exactly right the first time. Professional kitchen designers recommend physically measuring twice to confirm dimensions when renovating.
