When it comes to style, you have undoubtedly heard about the flush mount and undermount sinks. There are misunderstandings that they are both the same thing. Even though they look almost the same, they certainly aren’t.

The structural distinction between them is the undermount sinks require a specific room in the countertop to be installed. Whereas, flush mount sinks require a whole countertop that will be integrated with the sink.

Flush Mount Vs Undermount Sink

What Does Flush Mount Mean?

As per the word book, flush mount means mounting something with the wall. Additionally, the outer body is not visible and integrated into the walls. Leaving out the useful surface on the top surface of a wall. 

However, when it comes to flush mount sinks, the sinks remain evenly fitted with the countertop. Moreover, supported by the base cabinets.

You can instantly tell that it’s a flush-mounted sink if you can’t identify the sink from the countertop. It’s because the countertop and the basin itself are made from the same material and remain seamless.

What is an Undermount Sink?

When a countertop has a cutout, it’s for an under mount sink to be installed. The cutout remains observable and is exposable to water. Thus, the water would interact and cause unhygienic conditions.

As much as the material used in the countertop needs to be strong, the weight that the basin holds must be less. The sink is then attached to the countertop using silicone adhesive. Additionally, clips are used in the base cabinets to support the undermount sink.

Overall, an under-mount sink is exactly what it sounds like. It’s a sink that sits deep below the top and makes cleaning large dishes easier with its depth. You can use an undermount kitchen sink with a granite countertop to maximize your kitchen’s vibe.

Moreover, an undermount bathroom sinks are a great addition to modern bathrooms.

In the installation process, none of them are easy. Both flush mount sinks and under-mount sinks require experienced helping hands to get them installed. So, don’t even try to do it yourself if you are not experienced at all.

However, under-mount sinks are certainly easier to install. Installing an under-mount sink involves taking measurements of your desired sink and sizing it accordingly. Later, use silicone adhesive and some clips to make the sink stick to it.

Difference 2: Price

You would need to buy the whole set of countertops and the integrated sink. There’s no doubt why a flush mount sink wouldn’t cost more than an under-mount one.

However, that doesn’t make the price difference far-reaching. With an under-mount sink, you need to make sure that water doesn’t get exposed to it. For that to happen, you would need to hire an expert that knows the installation process.

Additionally, the use of solid material like marbles are recommended. Yes, you can surely use cheaper materials like stainless steel, but in the long run, it will cost more.
