When you think of making coffee, what are the two primary ingredients that come to mind? The answer that you probably gave is ground coffee beans and water. Since you will be using water when brewing those coffee beverages your customers are clamoring for, your coffee shop is going to have to have its fair share of sinks. So, exactly how many sinks does your coffee shop need?

Depending if your coffee shop has restrooms, you will need at least three sinks for a coffee shop. Because you will have to wash, rinse, and sanitize dishes, a three-compartment sink is an absolute necessity for your coffee shop. For handwashing, you will also have to have at least one additional sink that is separate from the three-compartment sink, according to Coffee Shop Startups. You are also going to need a sink for rinsing your mops. There must also be a sink present in your coffee shop’s restrooms. This gives a small coffee shop with a restroom a total of four-five sinks that are necessary to conduct business.

In this article, I am going to take a look at each room where a sink would be present, describe what type of sink you will need for that room, and examine the most efficient way in which the room should be laid out for ergonomics of your coffee shop.

Kitchen or Food Prep Area

Many different types of sinks can be found in the kitchen or food prep area of a coffee shop. These sinks often come in multiple compartment layouts, ranging anywhere from a one-compartment sink to a four-compartment sink. For a small coffee shop with limited space, an underbar sink is always a viable option. Two of the main factors to consider when choosing which sink you will put in the food prep area of your coffee shop are the size of your coffee shop and how ergonomic you would like your coffee shop to be. The two most popular sinks found in coffee shops are the underbar sink oh, and the three-compartment sink.

Three-Compartment Sinks

The largest sink in your establishment will be found in your kitchen or food preparation area, which is typically located in the back of the house, according to the Espresso Blog. is where you will put your three-compartment sink for washing, rinsing, and sanitizing all of the dishes and silverware you use throughout the day. Having a three-compartment sink does come with one potential downside. Perhaps the biggest caveat of using a three-compartment sink is that they normally do not come with a faucet attached to them.

Of course, this means that you are going to have to purchase a separate faucet for the main sink in your coffee shop. However, three-compartment sinks usually come with at least one drainboard. If your coffee shop has enough space, the three-compartment sink will assist your employees in being more efficient and productive. By having a three-compartment sink in the back of your coffee shop, where most of your food is being prepared, you can ensure that the tools and dishes used for preparing food or being washed immediately.

Underbar Sink

Underbar sinks are perfect for coffee shops that are in the unfortunate position of having a limited amount of space available in which the Baristas can work, per the website CK How Many Sinks Does A Coffee Shop Need? (Three Design Selections)Kitchen. These space-saving sink solutions are perfectly ideal for cramped quarters. Typically installed behind the counter, underbar sinks are located with ergonomics in mind. The location of the sinks allows Baristas to reach them with minimal effort when they are washing dishes, cups, or small tools they use to make coffee.

Underbar sinks are usually made from rust-resistant, corrosion-free stainless steel and usually have at least one drainboard attached to them. Unlike the three-compartment sink previously mentioned, underbar sinks usually come with a faucet attached to them. In an area with limited space, this would be most beneficial, as you will not have to worry about finding extra counter space that you do not have to accommodate a faucet.


Whether or not you choose to have public restrooms in your coffee shop, you will undoubtedly have at least one restroom for employee use. The restroom will have to include at least one sink for washing hands once employees are finished with their restroom breaks. The layout in which you choose to place your restroom sink will be entirely dependent on the size of your restroom. Large coffee shops and restaurants with multiple stalls usually have a row of sinks in an area separate from the stalls. However, if you happen to own a smaller coffee shop, your shop may have a small restroom that only includes one toilet.

Perhaps the most optimal placement of your restroom sink will be close to the toilet to eliminate as much unnecessary touching of surface areas as possible when your employees are finished. Although, this is not necessarily a matter of ergonomics, more a matter of being sanitary. If you give it some consideration, the first thing you normally do once you are finished in the bathroom is to wash your hands. Placing your bathroom sink near the toilet will allow your customers or employees to wash their hands immediately upon being done in the restroom.

Mop and Broom Area

Chances are, your coffee shop will have at least one area in which you store your cleaning supplies, such as mops, brooms, and cleaning products. In terms of efficiency and How Many Sinks Does A Coffee Shop Need? (Three Design Selections)productivity, as well as remaining sanitary, I believe that including a sink in which you can wash out your mop once you’re finished using it would be optimal. Maps are generally quite dirty, picking up quite a bit of dirt, grime, bacteria, and germs that are spread across the floor of your coffee shop. It would only make sense to want to clean your mops thoroughly and quickly once you are done using them.

Speaking in terms of ergonomics, employees are much less likely to complete a task if it requires them to take multiple additional steps to finish it. If you expect your employees to be productive and efficient in their work, having a mop closet that includes a sink would be beneficial to both you and your employees.

This is another area in which being sanitary works in conjunction with being ergonomic. Besides, wouldn’t it be counterproductive if you had to walk across your freshly mopped floor to rent a filthy mop, spilling dirty water along the way? This is a job that most people do not prefer to do once, much less twice. That makes the layout of your coffee shop even more important than you might have previously thought.


Who would have thought that sinks would play such an important role in the layout and the productivity of your coffee shop? Even the most basic of coffee shops should contain a minimum of four sinks. The placement of these sinks should be in the kitchen or food prep area, in the restrooms, and in the cleaning supply closet.

We have also determined that the size and placement of your coffee shop’s sinks will be determined by the size of your coffee shop, along with the perceived productivity and flow of the coffee shop. In a business, we’re getting the customers taken care of as efficiently as possible is one of your most important priorities, ergonomics matter more than you think. It is of the utmost importance to keep this in mind when you are either selecting a building where you want to establish your coffee shop or designing your coffee shop’s layout.
