How to Pick Between Top Mount vs Undermount Kitchen Sinks for Your Remodel
Upgrading your kitchen sink can make a big difference in both form and function. When choosing a new sink, one of the first decisions you'll face is whether to go with a top mount or undermount design. Both have unique benefits that appeal to different homeowners and kitchen aesthetics.
We'll compare the key differences, pros and cons, costs, installation factors, and help you determine which is better suited for your kitchen remodel.
What is a Top Mount Sink?
Also known as a drop-in sink, a top mount sink sits on top of the counter or sink base. The outer lip rests on the countertop while the body of the sink drops below into a pre-cut hole.
Clips and mounting hardware secure the sink in place by pressing down from above. Some top mount sinks also have a ledge or legs beneath for added support. From above, you see the rim of the sink surrounding the countertop cutout.
Benefits of Top Mount Sinks
- More affordable purchase price
- Easier for DIY installation
- Come in a wider range of materials
- Often better at absorbing noise
- Rim can hide rough counter edges
With a lower cost and easier installation, top mount sinks are ideal for budget-friendly remodels. The lip around the sink also minimizes noise from running water and garbage disposals. If you have an existing counter with a rough or uneven cutout, the rim can conceal imperfect edges.
Drawbacks of Top Mount Sinks
- Visible lip around the sink
- Lip can collect gunk and bacteria
- Not as sleek/seamless as undermount
- Limited design flexibility with countertop
While convenient for installation, the lip around a top mount sink can be a nuisance long-term. It interrupts the smooth counter space and provides a place for grime, food, and bacteria to accumulate. The lip also somewhat limits your countertop material and edge profile options.
What is an Undermount Sink?
As the name implies, an undermount sink is installed underneath the countertop. The sink edges align with the bottom of the counter and are fastened into place with adhesive, clamps, or clips.
When viewed from above, an undermount sink appears to flow seamlessly into the countertop material with no lip or edge interrupting the surface. This provides a clean, modern look.
Benefits of Undermount Sinks
- Seamless, contemporary aesthetic
- Easy to wipe crumbs/spills into sink
- Doesn't disrupt continuous counter space
- Allow for thicker, high-end countertops
The smooth transition of an undermount sink lends a refined, upscale look, making it a popular choice for contemporary and designer kitchens. Without a lip getting in the way, it's easy to brush crumbs and wipe spills directly into the basin.
Drawbacks of Undermount Sinks
- More expensive upfront cost
- Challenging for DIY, may need pro install
- Not as effective at reducing noise
- Can lead to water damage if not properly sealed
Undermount sinks come at a higher purchase price, especially for premium materials like stainless steel or fireclay. Installation is also trickier, often requiring a professional to ensure proper sealing and prevent leakage under the countertop.
Key Factors to Consider
When deciding between a top mount vs undermount sink, there are a few key considerations to help determine which is right for your kitchen remodel.
Budget
In most cases, top mount sinks provide cost savings on both materials and installation compared to undermount. Top mount styles start under $200, while undermount often exceed $500 with some premium options over $1000. If maximizing value is critical, top mount provides quality at a more affordable price point.
Skill Level
Top mount sinks are generally easier for DIYers and beginners to install as they simply drop into the countertop hole and are secured from above. Undermount installation is best left to experienced pros as the sink must be mounted underneath and sealed properly to prevent leakage and water damage.
Design Aesthetic
If aiming for a contemporary, seamless look, undermount sinks are unmatched. Their smooth transition highlights countertops and creates an upscale appearance. Top mount sinks have a more traditional style with the visible lip around the perimeter.
Noise Concerns
With an added layer of insulation from the sink rim resting on the countertop, top mount sinks tend to do a better job absorbing noise from running water and appliances like disposals. Undermount sinks lack that sound barrier, allowing more audible clatter.
While top mount and undermount sinks achieve a similar end goal, the key differences come down to factors like budget, skill level, design preference, and noise insulation. Top mount sinks are generally more wallet-friendly and beginner-friendly, while undermount sinks provide a modern, seamless look.
For a kitchen remodel, think carefully about your needs, style, and capabilities. Compare the pros and cons of each thoroughly before committing. With some smart planning upfront, you can select the ideal sink type to both function flawlessly and look stunning in your new kitchen design.
