It's two sinks installed in your bathroom, usually into the cabinets. The vanity countertop accommodates the two sinks, and they're typically all connected together in the same slab of counter. It's two sinks, two faucets, and double the convenience.
If this sounds familiar, you are not alone. The most common reason to choose a double sink is that you need more space because you share the bathroom with another person.
Deciding Between Single and Double Vanities. Double bathroom vanities with tops offer all the benefits of a vanity times two, providing space for two individuals to get ready each morning, less stress about sharing the bathroom, and more convenience and flexibility overall.
Double sink vanities tend to run between 152 cm and 182 cm in width. Dimensions for vanity height and depth are typically similar to that of single bathroom vanities. This being the case, they do take a significant amount of floor space within a bathroom but this also means they have extra storage capacity too.
Double sink vanities, on the other hand, usually measure 60 to 72 inches. There are some 60 to 72 inch vanities that also come in a single sink version. The determining factor should be how you plan on using the space.
Dual Basins in the Master Bathroom
The most common place to see a dual-basin design is in the master bathroom. These are sometimes called a his-and-hers vanity design. The basic idea is easy to see: one sink for each half of the couple so that they can use the bathroom vanity at the same time.
For a single vanity, the most popular widths are 24", 30", 36", 48", and for double vanities the most popular widths are 60" and 72", but start at 48". The standard depth of a vanity is typically around 20", but narrower options are available.
60-Inch: If you've been wanting his and hers sinks, the 60-inch bathroom vanity is the ideal size for it. Offering two sinks, a generous amount of countertop space, and plenty of storage space, it is perfect for couples.
If you do the math, that calls for a minimum of 60 inches, or 5 feet of wall space. And 5 feet really isn't enough for comfortable, simultaneous use of both lavs. Six feet is a real-world comfort minimum, with 36 inches between lav centers.
The most common bathroom vanity widths are 24, 30, 36, 48, 60, and 72 inches. For single-sink cabinets, the average bathroom vanity width range is between 30 and 48 inches. For double vanities, a width range of 60 to 72 inches is standard.
Double Bowl Kitchen Sink Cons
For one, double bowl sinks do take up more countertop real estate. What's more, then also eat away at your under counter storage space. While they take up more room in the kitchen, a double sink doesn't necessarily allow for easy washing of large items, such as casserole dishes and pans.
Double Bowl Sinks Allow You to Separate Clean and Dirty Dishes. People who enjoy cooking or baking and also hand wash dishes afterwards often choose double-bowl kitchen sinks because it allows them to do both at once and splitting up tasks between two bowls.
As a general rule, if you have a large enough space for a double vanity that will still allow for adequate counter and storage space then certainly two sinks would be most desirable both for practical use as well as for resale value.
Sellers expect that they will get at least a majority return on investment (ROI) on their upgrades while increasing the chances that their homes sell fast. If you are considering a bathroom upgrade to make your home marketable, a double sink is a good place to start.
Depending on the design of your sink, it may have one, two or three holes, and they may appear between the faucet valves, facing toward you, or under the near rim, facing the mirror. They serve two functions: to prevent an overflow with the drain stopper engaged and to provide an escape route for air in the drain.
While you may find double bathroom sinks in various sizes, the standard size and shape is circular between 18-20 inches and about 8” deep. The distance between the two sinks, measured from each of their centers, should be at least 30 inches, if not more, depending on the total length of your vanity.
It's entirely possible to replace a single sink with a double sink, although it requires a bit of work and money. Double bathroom vanities, sometimes called “his and her” sinks, can be more practical in situations where two people go through their morning routines simultaneously.
If you're building in your bath, you've got more flexibility with the depth of tiling around the edge. Make sure your door swings clear of your vanity and that you allow at least 100mm–200mm between a shower screen and vanity for cleaning.
The standard and minimum distance must be between the vanity and wall between 21-30 inches and 15 inches. To measure this distance, first, measure the length of the vanity and make a point at the center. Then measure the depth of the vanity and make a center point.
Double vanities aren't off-limits in small bathrooms. If you're navigating a small space, look for creative ways to make the most of what you've got. A double sink will transform your vanity without adding much extra width, and if you spring for a wall-mounted option, you can save space under your sink, too.
Most codes require at least 15 inches (measured from the center of the toilet) from any side wall or obstruction and not closer than 30 inches center to center to any other sanitary fixture. (The NKBA actually recommends 32 inches.) There should be at least 24 inches of clear space in front of a toilet or bidet.
While the standard bathroom counter height is generally between 30 and 34 inches, some homeowners may prefer what's called “comfort height” for their vanities. Comfort height vanities tend to be around 36 inches high.
Single vanities are the most common, and they tend to have widths measuring between half a metre and just over one metre (1200mm). Double vanities are usually between 1500mm and 1800mm wide. A double vanity comes with several benefits.
What is the smallest bathroom vanity size? Technically, a bathroom vanity can be as small as you want it to be, but if you're opting for a ready-made one, you won't find many options smaller than 24 inches wide.
According to its definition, the bathroom vanity is a combination of a sink and extra storage around it. Besides storage, it also serves to hide exposed plumbing so as to keep things looking neater and tidier. While bathroom vanities are very efficient for hiding the plumbing, they may not have enough storage.
