Top Mount Sink vs Undermount Sink: Which Is The Better Option For Your Kitchen?

Top Mount Sink vs Undermount Sink

When choosing a sink for your kitchen, weighing the pros and cons of each option is important. Top-mount sinks are generally more affordable and easier to install than under-mount sinks. They also require less countertop space, as the edge of the sink sits on top of the countertop surface. On the other hand, undermount sinks have a better aesthetic appeal since they blend in with your countertop seamlessly. Additionally, their seamless design allows for easy cleaning since dirt and grime can be wiped directly into them without having any crevices which could trap food particles or bacteria. Ultimately, both types of sinks have advantages and disadvantages – you must decide which is best based on your budget and preferences!

Top-mount Sink

A top-mount sink is one of the most widely used and versatile kitchen sinks. They are installed above the countertop with various clips, screws, or bolts. It features an easy-to-clean surface due to its raised lip that prevents water spills from entering the cabinet below. Top-mount sinks come in different materials, such as stainless steel, granite composite, and fireclay. They also have a variety of sizes and depths to fit into any kitchen size or design style. They are also relatively low maintenance as they don’t require much special care like other types of sinks. With its reliable function and attractive appearance, it’s no wonder this style is one of the most popular modern kitchens!

Advantages of a top-mount sink

Easy to install:

Installing a top-mount sink is relatively easy compared to other sinks. Depending on the type of sink, mounting it can be done in as little as one hour. The first step is to lay out where the sink will be located relative to other countertop fixtures and allow for adequate space around them. Once the rough position is marked, pre-drill holes into your countertop surface before putting a sealant underneath, install lag bolts using an adjustable wrench while being careful not to overly tighten them, which could cause damage or breakage. Place washers between the sink flange and underside of the countertop for added support with a screwdriver, then twist all nuts onto their respective bolts until tight. Apply caulking agents between all gaps ensuring optimal watertightness, and finish off by testing all connections for leaks using soapy water or plumbers putty if necessary.


Top-mount sinks are less expensive than under-mount sinks. They’re also easier to replace, and the installation process is less complicated, meaning you can save money on labour costs.

Diverse options:

Top mount sinks are available in different shapes, sizes, materials, colours, and styles. You can choose the one that complements your kitchen’s design and blends well with your countertops.

Undermount Sink

Undermount sinks are becoming increasingly popular in modern kitchens. They are mounted underneath the kitchen counter, leaving a smooth, seamless finish with no visible edge. They are often held in place with glue and clamps, giving a secure and sturdy seal.

Advantages of an undermount sink

Easy to clean:

Undermount sinks have a smooth surface that makes them easy to clean and have no exposed edges to trap dirt and debris.

Increased counter space:

Since it’s mounted below the countertop, an undermount sink saves considerable counter space. This feature makes it ideal for smaller kitchens and spaces.

Aesthetically pleasing:

The seamless, modern look of under-mount sinks makes them aesthetically pleasing to many homeowners.


Choosing between a top-mount sink and an under-mount sink depends on your needs, style, and budget. Top-mount sinks are advantageous because they are easy to install, cost-effective, and have diverse options. Undermount sinks are desirable due to their easy-to-clean surface, increased counter space, and modern style. However, they have limited options and are more expensive to install. Ultimately, the decision lies in your preferences, and once you make an informed choice, you’ll be glad you did.
