When it comes to sinks, there are so many different models for different uses that it really feels overwhelming, and one of the types is a bar sink.

In this article, I will teach you exactly what is a bar sink among other things regarding them. In addition, I will teach some things about sinks in general and the different aspects of bar sinks. Before we go further into the world of sinks, we need to understand what exactly a bar sink is?

Bar sinks, also known as wet-bar and prep sinks, are small sinks often used for convenient rinsing, hand washing, or other quick tasks. Bar sinks are usually made from stainless steel although there are various material choices. They have usually shaped either square, round, or rectangular.

Bar sinks are found everywhere, from domestic kitchens at home to large commercial-grade kitchens. If you want fully understand what a bar sink is, we need to go more in-depth into each feature they offer, so let’s take a look at what kind of bar sinks are there.

What kind of bar sinks are there

The first difference between bar sinks is the installation types. There are 3 main installation methods that affect the price and design it. Let’s take a look at installation methods.

Drop-In bar sinks

Drop-in sinks are the easiest to install because you drop the sink into the pre-designed opening in the countertop. Drop-in sinks will have the edges of the sink on top of the countertop, which shares opinions about whether they look good or not. These sinks are easy and affordable options, so if it is mainly used for convenience, drop-in sinks are the go choice.

Under-mount bar sinks

Under-mount sinks are installed under the countertop hiding the sink better and offering the opportunity to conceal it by placing something on it, usually a cutting board or a stylish cover that comes with it. Cleaning around the under-mount sink is easier because there are no corners where dirt can get stuck. In most cases, under-mount sinks are installed to solid and durable materials such as wood or granite.

Farmhouse bar sinks

Farmhouse sinks really expose the full sink; therefore, they are usually made from more expensive materials and are more costly than the other types. Usually, farmhouse sinks are larger than bar-sinks; however, some models are designed smaller. Farmhouse sinks are usually bought by people that want to include the sink well into their decor.

Freestanding bar sinks

Freestanding wet sinks are commonly found in restaurants because they can stand alone; therefore, they can be added to the already working layout. Freestanding sinks are nearly always made from stainless steel because they are mostly intended for commercial businesses.


Now that we know the installation methods, we need to check what materials are available for bar sinks.

Stainless Steel

Stainless steel is the most common material because it is sanitary, easy to clean, durable, and cheap. These sinks are also resistant to corrosion, rust, and damage.


Fireclay is made as it sounds, constructed made from clay and heated hard in extremely high temperatures. Usually, fireclay sinks are coated with porcelain enamel, and the two together make a durable and beautiful sink that is smooth and pleasant to touch. Fireclay sinks


Ceramic sinks have that beautifully smooth and creamy feel in addition to their easy-to-maintain feature. Ceramic bar sinks are usually found only from home because they can chip or get damaged in other ways if not being careful.

Cast iron sinks are really heavy and durable and usually coated with porcelain enamel, making them easy to clean and beautiful. There are many colors that porcelain enamel coating enables, so the sinks aren’t necessarily black like cast iron.


Copper sinks are stunning in addition to their durability and maintenance perks. An authentic copper sink is a pure copper that gives the sink a cool feature that kills harmful bacteria on its own.

Natural Stone

Natural stone bar sinks are often made from granite, quartz, or marble. They offer a great variety of colors, and they are arguably the most beautiful sinks out there. That kind of beauty doesn’t come without cost because you will need to use a stone sealer from time to time to keep the sink in good condition.

Lastly, bar sinks come in different shapes, which really don’t matter to the performance. It’s really more of a personal choice which one do you prefer the most. I have listed the 4 main shapes of bar sinks below.
