A comprehensive guide of what size bar sink should you buy

You’ve decided to make your life easier and add a bar sink to your home. However, you know what size sink you should buy? Here, we
We have put together a comprehensive guide on what size bar sink you should buy. A bar sink, also known as a utility sink or prep sink, is one of those things I didn’t realize I needed until I actually started using it. Let’s dive deeper into what factors to consider so you can also get the best size bar sink for your needs.

Most commonly sold bar sinks are rectangular in shape, with a length of between 9-18 inches on each side and depth around 6-10 inches. Circular bar sinks are usually around 9-18 inches in diameter and 7-10 inches at their deepest.

There are four important factors to consider when deciding what is the best size for a bar sink:

  • The size of the counter and base cabinet that will hold the bar sink
  • The amount of space available between the top of the pipes and the bottom of the sink
  • Storage space in the base cabinet
  • The intended use of the bar sink

Now let’s take a closer look.

The Size of Your Base Cabinet Determines the Size of Your Bar Sink

The most important part of the comprehensive guide on how to buy a suitable size bar sink is this.

Wet bar sinks are designed to be mounted on base cabinets. The sink you choose should be at least 3 inches (7.5cm) smaller than the base cabinet you will be anchoring your counter on top of.

Measure the length and width of your base cabinet and subtract 3 inches. For instance, in the example in the image below the maximum size of your bar sink should be 17″ x 12″.

If your base cabinet is 20″ x 15″, then choose a bar sink that is 17″x12″ or smaller

Check Your Plumbing

As with any sink, the size of the bar sink you can have depends on the amount of space there is between your pipes and the bottom of the sink.

You need to figure out the depth of the space which your sink will sit in. Measure the height of the pipes beneath the sink and the depth of your sink and make sure there is enough space. If you have flexible pipes this is not really a big concern, but in case you have metal pipes be sure to check.

A Misfit Bar Sink Will Cost You Storage Space

Remember to consider factors such as shelving units or drawers beneath your installation space that could get in the way of seating your sink.

You don’t want to have to cut out or demolish valuable storage space in your kitchen because you ordered the wrong depth sink. Altering your base cabinet may void the warranty and could compromise support strength.

Having to remove or redesign shelving units or cut your base cabinet to make space for an oversized sink could increase your renovation budget. Blowing a renovation budget is never a good thing, especially if it’s caused by a measuring or planning oversight!

Don’t Forget About Counter Space!

Depending on the intended use for your sink and nearby work area, you likely don’t want your sink to take up all of your counter space. You may need a food prep area or space for things like your blender, wine glasses or other kitchen tools.

If you’re short on counter space, consider getting a smaller sink or another solution like a fitted cutting board. These sit nicely over your sink to add more counter space and create extra work space when the faucet is not in use.

You could also consider a prep sink that comes with a custom cutting board out of the box. 

Consider the Many Uses of a Bar Sink

Before making a decision, think hard about what all you’ll be using the sink for.

If you simply want it so that you have access to water as a mixer for your drinks you will not need a very big sink. Conversely, if you want to be able to store 12 beers on ice, or use your wet bar sink for vegetable prep, a bigger sink is probably the way to go.

Having said that, most people prefer a sink that is larger rather than smaller. After all, it’s rare to hear someone complain their sink is too big! A bar sink with small dimensions could become crowded and cluttered if used for too many things.

To get a sense of how much room you will need, use your main full-size kitchen sink to do a trial of what you want to do in your prep sink.

For example, if you want to wash tall wine glasses and other dishes in your prep sink, then place a few tall wine glasses and dishes in the sink and measure the area required. This will give you an idea of what size prep sink you should be considering.
