You don’t want to clean paintbrushes or deal with stained clothing in your kitchen sink. A utility sink provides a convenient place to handle dirty tasks or treat stains before tossing laundry in the wash. But you need the right utility sink dimensions to make it work for you.

Utility sinks come in small and larger sizes, with average dimensions of 23 by 20 inches and 13 inches deep. Smaller wall-mounted or freestanding sinks are 16-inches square and 10 to 12 inches deep. These smaller sinks are ideal for a tiny area if you want to maximize your space. Double sinks average about 13 inches deep and 40 by 22 inches.

Utility sinks come in a wide range of sizes and styles, and there are no set dimensions from model to model. Therefore, always measure your available space to determine what size sink will work best for you.

What Are The Average Dimensions Of A Utility Sink?

The average size of a utility sink is approximately 23 inches by 20 inches and 13 inches deep. You can find utility sinks in several styles, including freestanding, drop-in, under-mount, wall-mount, and even farmhouse styles.

Utility sinks are prized for their durability and functionality in spaces like laundry rooms, garages, basements, workshops, and more. Although you can pinpoint an average size for a utility sink, it’s only one option of many.

Since you can find utility sinks in various environments, you’ll notice that they come in many sizes. You can choose from tiny sinks that you can squeeze into a small laundry space or workshop. Or, at the opposite end of the spectrum, you can select larger double sinks that are extra deep.

How Big Is A Double-Utility Sink?

Double utility sinks average 40 inches long, 22 inches wide, and 13 inches deep. But these numbers can vary a few inches in either direction. For example, a smaller double sink can be closer to 35 inches long, 21 inches wide, and 9 inches deep.

Some double sinks are only 30 inches long. However, keep in mind the smaller the length, the smaller each individual basin. Therefore, really consider which style of the sink will be the most useful to you.

Do you need two basins even if they’re small, or would one single large sink work better for you? A more oversized double-sink option is 46 inches long, 23 inches wide, and approximately 24 inches deep.

A double-utility sink is a true workhorse if you have room for it. You can use one side for washing and one side for rinsing. Or have items soaking on one side and still have access to the other side for other tasks.

What Are Small Utility Sink Dimensions?

One of the smallest utility sinks is roughly 15 to 16 inches square and only 5 inches deep. This depth would only work well for handwashing and small rinse jobs. But if it’s all you have room for, it’s better than nothing.

You can also find slightly larger small utility sinks that are 19 to 20 inches square and 9 inches deep. One common feature among the majority of small utility sinks is they are square.

If you want to maximize your available space, consider a wall-mounted sink. If you do opt for a freestanding or cabinet model, look for something with storage. You can also hang a curtain around the bottom of a freestanding sink on legs to create a hidden storage area.

How Tall Is A Utility Sink?

If your sink is in a cabinet, then it’s probably about 36 inches from the floor. This height is due to the fact that your cabinet is likely counter-height in a laundry room or workshop. A freestanding sink or wall-mount sink ranges from 30 to 36 inches from the floor.

What Is A Good Size For A Laundry Room Sink?

An ample size for a laundry room sink is between 22 and 25 inches and 13 to 15 inches deep. This size should be enough room for you to tackle basic laundry tasks and other odd jobs.

It should also fit well in most standard laundry rooms. You could find this size as an under-mount, drop-in, wall-mount, or freestanding sink. If you need a deeper sink, you can find many freestanding models that can be as deep as 24 inches.

How Wide Is A Standard Laundry Room Sink?

A standard laundry room sink is roughly 22 to 23 inches wide. Most drop-in, wall-mount, and under-mount styles come in these sizes. It’s one of the most popular widths for a laundry room or utility sink.

The smallest laundry room sink is approximately 21 inches by about 19 inches wide. It is most commonly in a drop-in or undermount style in a cabinet. This is a better fit for smaller spaces but still gives you some decent room to work.

What Is The Difference Between A Laundry Sink And A Utility Sink?

People use the terms laundry room sink and utility sink interchangeably. Basically, most often, the sink you find in a laundry room is a utility sink.

These sinks are perfect for laundry areas since they are usually deeper than traditional sinks. Also, utility sinks are more durable and can withstand more rough-and-tumble use and wear.

How Do You Choose The Right Size Utility Sink?

With so many styles and sizes to choose from, how do you choose the right size utility sink for your space? You need to measure your available space, consider your existing plumbing, then select a suitable style.

The budget also plays a factor in the decision. Although you can find many affordable utility sinks, if you need to make any changes to plumbing, it adds to your overall costs.

It’s also important to consider how you will use the sink most of the time. This factor will influence the style and depth of your sink.

Measure Available Space

Obviously, before you decide on the best size sink, you need to know how much room there is for it. Take careful measurements of the laundry room or the area where the sink will go. You need to measure the length, width (how far out the sink will come from the wall), and available height.

Height is important for freestanding sinks. If you already have a cabinet in which you plan to place an undermount or drop-in sink, it already dictates the height. A wall-mount sink, you can place as necessary in relation to the plumbing, etc.

Once you know the available space, you can choose from sink sizes that are equal to or less than these dimensions.

Consider Existing Plumbing

Your budget will be a large determining factor for this step. If you’re trying to keep things affordable, you might need to make some compromises based on your current plumbing situation.

Therefore, to save money and time, consider your existing plumbing when buying a utility sink. If you don’t need to reroute plumbing, you’ll save considerably. Therefore, measure around the pipes, valves, etc.

If the current location of the plumbing doesn’t work for your overall design, then you may need to consider moving it. If you do decide to do this, consult with a plumber to ensure everything is done correctly and up to code.

When working with existing plumbing, you will also want to take note of where it is on the wall. This placement will influence the height of where you place a wall-mount sink. It can also affect how tall of a freestanding sink you should get.

Choose The Best Style Utility Sink

Based on the size you need and your current plumbing, decide on the best style sink. For example, if you already have a cabinet in place, a drop-in or undermount sink makes sense.

If the space is empty, you might opt for a freestanding sink with legs. Or, if you are limited in space, a wall-mount sink might be your best option. If you have lots of room, you might prefer a double sink.

But what will you use your sink for? If you plan to soak large items, you might prefer a single large, deep tub sink. However, a shallower sink might be better if you plan to bathe your small dog. As you can see, how you want your sink to function will play a large role in the style you choose.


A utility sink is an excellent functional addition to laundry rooms, workshops, and similar spaces. They are durable and create a perfect place for washing, scrubbing, soaking, cleaning, and other household tasks.

The average utility sinks are approximately 23 by 20 inches and 13 inches deep. You can find smaller wall-mounted or freestanding sinks as little as 16-inches square and 10 inches deep. These smaller sizes work well in tinier rooms or spaces where you need a sink.

But if you have the room, a double utility sink can provide two times the convenience. Some of these double sinks can be 40 to 45 inches long and even 24 inches deep.

However, utility sinks don’t conform to any one set of dimensions. Therefore, you can find multiple sizes in various styles, including freestanding, drop-in, under-mount, and wall-mount designs.

Before you choose your sink, measure the available space, and consider the current location of your plumbing. Then you can decide on the best sink for you based on your needs.
