This article will take you to the world of bar sink dimensions and explore different sizes and styles available with tips for choosing the perfect sink for your space.

What is a Bar Sink?

Bar sinks, also known as prep sinks, island sinks, entertainment sinks, or wet bar sinks, are smaller sinks that are typically located in a home bar area or a designated entertainment space. They are designed to be used for food preparation, cleaning, and serving beverages. While they may be smaller or more prominent than the main kitchen sink, they are still an important part of the overall design and functionality of the space.

One of the main problems with bar sinks is that they are often an afterthought in kitchen design. Many homeowners and builders focus on the main kitchen sink and overlook the importance of the bar sink. This can lead to a lack of proper planning and a failure to consider the necessary dimensions for the sink. Proper planning and consideration of dimensions, height, and location are key to ensuring that the sink is functional and comfortable.

Where to Place a Bar Sink?

Leafloat also added some things to consider when choosing bar sink dimensions.

  • Countertop space. How much counter space is available in the area where the sink will be installed? This will help determine the maximum size that can be accommodated. For smaller space, you can choose a shallow basin.
  • Base cabinet size. The size of the sink should be proportional to the size of the base cabinet and should not take up a lot of space, leaving room for other important items such as cleaning supplies, glasses, and bottles.
  • Rough-in height. This is the distance from the top of the pipes to the bottom of the sink. It must be enough to allow for the proper installation of the sink and for the sink’s drain to connect to the pipes.
  • Type of use. Will the sink be primarily used for washing glasses and dishes or for food preparation? A bigger sink may be needed for food preparation.


Q1: How much distance is needed between the sink and the countertop edge?

A: The general rule of thumb is to have at least 1 ½ inches of clearance to ensure enough space for comfortable use and easy cleaning.

Q2: Are there any specific requirements for a bar sink drain size?

A: The diameter of the drain for a bar sink should match the size of the hole in the sink, which is typically 1 1/4 inches. However, the sink tailpiece, P-trap, and extension arm can be increased to 1 1/2 inches for improved drainage, but an adapter may be necessary to connect the trap arm to the waste line, which is usually 2 inches in diameter.

Q3: How much clearance do you need above a sink?

A: Typically, it’s about 18 inches. For comfort and ease of use, 20-22 inches is the recommended size bar sink. This allows enough space for users to comfortably wash their hands, brush their teeth, or wash dishes without feeling cramped or having to bend over too much. This measurement is from the sink rim to the bottom of the overhead cabinet.

Q4: What is the appropriate size for a bar sink faucet?

A: It will depend on the size of the sink or basin it will be installed in, as well as the homeowner’s personal preferences. But usually, bar faucets are 12 inches in length and 6-8 inches in reach.


In conclusion, pay attention to the importance of a bar sink when planning your home bar. It may seem like a small detail, but it can make a big difference in your space’s overall look and functionality. So, take the time to choose a bar sink that fits your style and needs.
