Collection: Drop In Bathroom Sinks

A Timeless Sink for Your Modern Bathroom

Drop-in sinks are named for the way they are installed. The sink is lowered down into the vanity, with the edges resting directly on the vanity itself. The easy installation process makes the drop-in sink a popular choice. Check out our selection of drop-in sinks today! 


What is a drop-in bathroom sink?

Because they are so easy to install, drop-in sinks are one of the most popular types of bathroom sinks you can find. Simply lower your sink into the cutout in your countertop and seal the edge that sits above your countertop with a water-tight seal. 

A main characteristic of a drop-in sink in the lip edge that rests above the countertop. This lip is great for preventing water from seeping between your counter and the sink, but it also happens to catch a lot of dirt and grime. Cleaning a drop-in sink does take a little more effort than other sinks.  


Drop-in Sinks vs. Undermount Sinks vs. Vessel Sinks

Drop-in and undermount sinks are pretty much opposite from each other. Rather than resting on top of your counter, undermount sinks are mounted from underneath the counter and attached with clips, epoxy, caulk, and sealants. 


Undermount sinks can be heavier than drop-in sinks and benefit from having sturdier types of countertops like granite or concrete. Undermount sinks are easier to clean than drop-in sinks because they have a smooth transition from the counter to the sink and no edge that could collect dirt.


Vessel and drop-in sinks are similar as they both install above the countertop. However, instead of dropping into a hole and having the sink partially underneath the counter, the entire vessel sink is above the countertop. 


Vessel sinks have the most variety in shape, size, and color compared to other bathroom sinks. They are great if you’re looking for something that can add a unique design element and be easier to clean. 


How to Measure for a New Drop-In Bathroom Sink

Though it’s simple to install a drop-in bathroom sink, it’s important to get all the measurements right before you start. Here are some basic things to remember when measuring your sink.

  • If you’re replacing an existing drop-in sink, make sure your new sink has the same dimensions. Measure the length (right to left), width (front to back), and depth (top to bottom) of your existing sink. Check that the existing plumbing will still work.

  • If you are placing a new drop-in sink in a new vanity, make sure that the dimensions match up with the hole for your sink and plumbing hook ups.

  • Drop-in sinks need at least one inch of clearance between the lip of the sink and the cutout so the lip has somewhere secure to sit. A new vanity drop-in sink can’t be smaller than the cutout. 

  • Check to make sure that there will be enough space to install your new bathroom sink faucet along with the new sink.

  • Measure available space around your sink, like countertops and space before the walls. Make sure there is some breathing room!

  • Measure the length, width, and depth of your vanity cabinets, making sure to check for sufficient clearance between the bottom of the sink and the bottom of the cabinet. Preferably you will have some room for storage!

  • If you’re installing double sinks in your vanity, make sure that your sink width and counterspace will allow for at least 30 inches between the center of each sink.



Are all drop-in bathroom sinks the same size?

No, you can choose from a variety of sink sizes for drop-in bathroom sinks. Small drop-in sinks range from 15 to 20 inches long and 9 to 12 inches wide. Medium sinks are 20 to 30 inches long and 19 to 24 inches wide. Large sinks are 20 to 50 inches long and 19 to 24 inches wide. The depths of these sinks range anywhere from 5 to 7 inches. 


Are all drop-in bathroom sinks round?

Round drop-in bathroom sinks are among the most popular shapes you’ll find, especially in older homes. However, there are lots of popular square, rectangle, and oval drop-in sinks too!


Can you replace an undermount sink with a drop-in sink?

Yes! Switching out an undermount sink for a drop-in sink is one of the easiest sink type switches you can do. Since they both require a hole in the countertop for installation, all you need to do is make sure that your drop-in sink is the same shape and large enough for the lip to have at least one inch of clearance to rest around the edge of the countertop.
