Everything You Need to Know About Undermount Sinks

Choosing a sink is an important part of any renovation for kitchen, bathroom or even wet bar. There are different styles, materials, and designs of sinks to choose from. The first thing to think about is the installation type, including the most popular installation methods: drop-in and undermount. For kitchen and bathroom renovations, there are some great benefits to undermount sinks.

Thinking about putting in an undermount sink? Here’s everything you need to know:

What is an Undermount Sink?

While drop-in sinks have visible rims on top of the counter, an undermount sink is installed from below. The rim attaches to the bottom of the counter, so it isn’t visible.

So how do undermount sinks stay in place? Undermount kitchen sinks or undermount bathroom sinks are held in place by high-strength epoxies, anchors and clips, and silicone caulk, according to Ask the Builder.


What Do Undermount Sinks Cost?

The cost for undermount sinks will vary depending on the size and material of the sinks. Typically, the cost will be between $250 and $800. You can explore the options at your local Vague & Vogue kitchen and bath showroom.

How is an Undermount Sink Installed?

The defining feature of undermount sinks is that they sit below the countertop in your kitchen or bathroom. Undermount sinks hang underneath the countertop, so the edge lip of the sink is mounted below the counter. This style creates a continuous flow from the countertop into the sink, in contrast to sinks that sit on top of a countertop with a visible rim.

Properly installing and sealing an undermount sink is critical for this style of bathroom or kitchen sink. To prevent leakage and any damage, you’ll want to make sure your undermount sink is properly supported and sealed. Your counter and supports need to be able to keep the sink in its place and hold its weight safely.

Installation of undermount sinks can be difficult for someone who isn’t familiar with this type of project. It can be easier to hire a professional. Most professionals will be able to install an undermount sink in less than 30 minutes.

Benefits of Undermount Sinks

For most people, the number one benefit of undermount sinks is how easy they make cleaning your countertops. Ease of cleaning is usually the biggest selling point, especially for kitchen sinks. Since the is no lip or rim acting as an obstruction, cleaning countertops are simple. You can wipe mess straight into the sink. Other types of sinks, like drop-in sinks, have higher rims which don’t allow for such easy cleaning.

Another plus? Undermount sinks give you more countertop space. Since they allow your kitchen or bathroom countertop to extend all the way to the sink, you get a little more countertop space with this type of sink. This is especially helpful for smaller kitchens or bathrooms.

Lastly, undermount sinks offer better resale value for your home than drop-in sinks, according to The Spruce.


Things to Consider with Undermount Sinks

While there are many benefits to undermount sinks, there are some things to consider before choosing one for your kitchen or bathroom renovation.

If you prefer DIY installation, this may not be the style for you. Undermount sinks are not as easy to install as drop-in kitchen and bathroom sinks. If there’s already a cut-out in place in the counter fitting the sink dimensions, a drop-in sink is usually simple and painless for homeowners to install on their own. This is not usually the case for undermount sinks.

Undermount sinks are typically more expensive than drop-in sinks. Costs are higher for both the materials and the labour involved in an installation.

Lastly, consider your countertop material. You can attach an undermount sink to all countertop materials except for laminate. Unlike undermount sinks, drop-in sinks can be installed on any and all countertop types and materials.
