You don’t need me to tell you about the importance of a bathroom sink!
Now, if you’re planning to get a new one, you understand that it’s not feasible to carry the whole thing to the store to get the right replacement. So, measuring it is a practical solution, but you may be wondering, “how to measure a bathroom sink for replacement purposes?”
And that’s what I will answer in the following sections.
How To Measure A Bathroom Sink For Replacement?
You will have a task cut out if you plan to get a replacement sink of the same style as the existing one. In this case, all you have to do is measure the length, depth, and width of the old one and choose a new sink with the exact dimensions.
To do this, simply take a measuring tape and start by measuring the width of the sink (or the open surface). Place the tape on either end (horizontally or vertically) and carefully pull it to the other side while ensuring that it forms a straight line. Note the number you get at the other end, and this will give you the width.
Follow the same technique to measure the length (the distance between the front and rear end of the sink) and the height (top to bottom). Once you get the numbers, ensure that the dimensions of the new sink aren’t bigger than those.
However, the process may come across as a bit tricky if you want a new style altogether. So, I will now break down the process of measuring into simple steps to guide you.
Step 1 - Measure The Installation Site
If you want to install a wall-mounted pedestal unit, then the exact site of installation will depend on your bathroom floor and the plumbing. The sink should be positioned in a way that doesn’t interfere with any pipes or fixtures, so make sure you leave enough room for them.
However, if you want to install a drop-in, undermount, or vessel sink, then consider the available space on the vanity countertop. Measure the width (front of the vanity to the rear wall it's mounted on) and move on to the length (across the surface).
But remember that you need to leave at least 4 to 6 inches of clearance on either side to accommodate toiletries, so the size of the new sink will vary accordingly.
Step 2 - Check The Compatibility Of The Faucet
Measure the height of the sink (from the bottom to the top rim or vice versa) to understand the level at which the faucet sits. If you aren’t changing the faucet, then the new sink should be installed in a way that the spout extends deep enough into the sink. This will ensure that the water will directly flow down the drain mouth.
Even if you’re installing a new faucet, it should follow the same rule of thumb.
Final Words
In my experience, measuring a sink isn’t a very difficult task per se. While I have always measured only the length and breadth, some people may choose to measure the interior to get an idea about how much water it can hold without flooding the floor.
But if you aren’t confident about your DIY skills, I’d suggest calling a professional plumber who will help you with the measurement as well as the installation.
