In terms of choosing the correct size for a laundry sink, as much as selecting the best color for your walls, it is a decision that will have a direct impact on your overall ease-of-use. A correctly sized laundry sink provides a user-friendly means for easily washing heavy items, streamlines workflow and minimizes clutter within the laundry area. Choosing a laundry sink that is either too small or too big for the area will lead to frustration in use. Modern laundry areas have transitioned from being strictly functional, utility type areas; today, they are both functionally efficient and visually appealing. Due to this, selecting the appropriate size for a Laundry Sinks has evolved into a critical component of the design process for these areas. Below, we provide information regarding all aspects of laundry sink size, including the common measurements of laundry sinks, how to determine the correct size for your laundry area and considerations for purchasing a laundry sink.
Why Laundry Sink Size Matters
A laundry sink typically serves several different functions. Many people soak their clothes, hand wash their most delicate garments, clean their cleaning supplies, rinse their mops, or wash dirty boots in their laundry sink. The wide range of tasks a laundry sink is required to accomplish, requires the laundry sink to be both useful and practical. A laundry sink that is too short will splash water when rinsing larger items and a laundry sink that is too narrow will not accommodate large amounts of laundry or large cleaning supplies. An overly large laundry sink may take up valuable countertop or cabinetry space in a laundry area that is too small. Finding a good compromise between functionality and space efficiency is the goal. Homeowners who are seeking a modern look for their laundry area tend to select larger and deeper laundry sinks than traditional utility sinks, particularly when selecting granite laundry sinks which are durable and aesthetically pleasing.
Laundry Sink Dimensions by Size Category
In terms of sizing, there are three main types of laundry sinks available; each type falls under its own category based on standard dimensions. Each category has its own unique features that make one more suited than another for specific spaces.
Compact Laundry Sinks
Compact (or "small") laundry sinks tend to be approximately as follows:
- Length: 400-450mm
- Width: 350-400mm
- Height/Depth: 180-200mm
Sinks with these measurements are generally suitable for laundry areas that have minimal square footage. They are not likely to accommodate very heavy or bulky loads but do a fine job with basic washing, rinsing, and daily cleaning activities. For example, if you currently have ample cabinet space and large appliance space in your laundry room and just need a little bit of extra space to use for a hand-washing station or small item rinse station then a compact sink would be a good fit.
Standard Laundry Sinks
The most commonly used sink sizes in today’s home building market are the standard (medium) size sinks. Typically, the measurements for the standard (medium) size sinks are as follows:
- Length: 500-600mm
- Width: 400-500mm
- Height/Depth: 200-250mm
The typical user finds a standard (medium) sized sink to be the perfect blend of functionality and space efficiency. Standard (medium) sinks are ideal for all of the typical laundry sink functions including soaking, washing small rugs, and washing larger household items. Additionally, standard (medium) sinks are often paired with a built-in cabinet or a bench top which is why many people choose to install them during their kitchen renovation.
Large Laundry Sinks
Large laundry sinks offer the greatest amount of function and are ideal for those who constantly wash bulky items such as blankets, pet beds, etc., or if you spend a great deal of time washing items such as sports equipment, tools, gardening supplies, etc. Dimensions of large laundry sinks can vary greatly depending upon the manufacturer and model of the sink, but the general dimensions can be expected to be as follows:
- Length: 700mm or greater
- Width: 500mm or greater
- Height/Depth: 250-300mm
However, since large laundry sinks take up so much space, they can only be installed in large laundry areas or laundry areas with large countertop surface area.
Choose the Right Size of Laundry Sink For Your Needs
Measure the Area Where You Will Be Placing the Sink
Before you even begin shopping for your new laundry sink, take some time to measure the space where you plan to install the sink. Measure the width of your cabinet space, measure the width of your countertop. Take into account the location of all of your other appliances, such as your washer and dryer.
Leave Enough Room Around the Sink
When you have determined what type of sink you need based upon the space available, keep in mind that you want to leave enough room around the sink to allow you to comfortably do your laundry.
Determine How Often the Sink Will Be Used
How often you do laundry will also help determine which sink is best for you. For example, if you usually hand wash your delicates, a medium-sized sink would probably be fine. On the other hand, if you always have to wash large items (like blankets) or large dog beds, a larger sink is better for this task. If you will only be using the sink to rinse your clothes quickly, or fill up a bucket, then a small sink would be just fine.
Choose the Best Type of Sink
Another important consideration is the type of sink to buy. Homeowners love granite laundry sinks because they are strong and resistant to scratches, and also easy to clean. Granite composite utility sinks are also very popular with homeowners today. They are generally larger and stronger than plastic utility sinks, which makes them perfect for heavy duty laundry chores. Granite composite sinks also add a professional appearance to modern laundry rooms.
Depth vs Width: Which is Important?
Both the depth and width of your laundry sink will determine how well it functions as a laundry area, however, for many people the depth of the sink is more important than the width of the sink. Why does the depth of a laundry sink make a difference? Because a deeper sink allows you to soak your clothes and prevent the water from spilling over the sides of the sink, provides you ample room to wash heavy or large items that would normally be difficult to clean in a shallower sink and helps keep the surrounding areas (such as countertops) dry by preventing water from splashing out of the sink. While having enough width in a sink to accommodate large items is helpful, the width is less important than the depth of the sink. Ideally, a sink should be as wide as needed to allow you to easily fit large items into the sink while at the same time, the sink should be deep enough to hold sufficient water to soak and wash the item.
What Size Is Best for Modern Homes?
In general, sinks for modern homes can have a good balance of both width and depth. A sink with 200-250mm of depth and 500-600mm of width would provide an ideal solution for many homeowners.
How Should I Choose a Sink That Fits My Laundry Room?
There are many different design styles for laundry rooms today; therefore, the sink should reflect the style of the laundry room. For example: If you have a small laundry room, then a single-bowl compact sink will probably be the best option for you. If you have a larger laundry room, then a large deep sink would give you a greatest amount of versatility for cleaning a variety of items. If you have a modern home, then a granite laundry sink would give you a durable and stylish addition to your laundry room. Your new laundry sink should look as though it was always a part of your laundry room and not just another large piece of equipment in your laundry room.
