It’s a common problem that can be a pain to constantly clean up, especially when you have so many other things to clean in your kitchen. Bondzil’s granite countertop silicone sealant might do the trick for you.

However, there are two types of kitchen sinks:

1. Drop-In
2. Under-Mount

Unless you have an integrated sink where the countertop and sink are all one piece, your sink likely falls into one of these categories.

The good news is that under-mount sinks can help you avoid the water build-up problem, making it easier to keep your sink clean without constantly having to scrub away at it.

What is the Difference Between Drop-In and Under-Mount Sinks?

The two types of kitchen sinks are drop-in and under-mount sinks, and the main difference between them is in how they are installed.

Drop-in Sink

Drop-in sinks are designed to “drop in” to a hole in the countertop, with the rim of the sink resting on top of the countertop surface.

The weight of the sink is supported by the countertop, and the rim of the sink is visible above the countertop surface.

This type of sink is easier to install and can be less expensive than an under-mount sink.

However, because the rim of the sink sits on top of the countertop, it can be harder to keep clean, as water and debris can collect around the rim.

Under-Mount Sink

On the other hand, under-mount sinks are installed from underneath the countertop.

The sink is attached to the underside of the countertop with clips or silicone sealant for the kitchen sink, so the rim of the sink is not visible above the countertop surface.

This type of sink creates a seamless, clean look and makes it easier to wipe water and debris directly into the sink.

However, under-mount sinks can be more expensive and more difficult to install than drop-in sinks, and they may require additional support structures underneath the countertop to bear the weight of the sink.

To summarize the foundational difference between these two sinks, we can say, Drop-in sinks are installed on top of the countertop, while under-mount sinks are installed underneath the countertop.

Drop-in sinks are easier to install and less expensive, but they can be harder to keep clean because the rim of the sink can collect water and debris.
