Standard Sink Size in Bathroom
Bathroom sink dimensions do have some standard set sizes, often determined by the shape of the sink. The depth of a bathroom sink is limited by code regulations and the vanity you have in your bathroom, but the shape and length are limited only by the space you have and the vanity design. The typical bathroom sink dimensions can also vary by mounting style, top-mount or under-mount. Materials and hardware can also have an impact on the size of a sink, but these limitations are often minimal. Here are some of the most common standard sizes:
Pedestal Sinks
The most common sizes are between 22 and 28 inches, but pedestal sinks do come in sizes as small as 15 1/2 inches in length and as long as 30 inches. The width of the sink is commonly between 17 and 20 inches.
Rectangular and Oval
These sinks have quite a bit of variety and can easily fit most bathrooms. Ranging from small to large size, the dimensions are as follows: Small vessel sink – Vary in length from 15 to 20 inches and in width from 9 to 12 inches. The depth of these sinks is commonly between 5 3/4 and 7 inches. Medium. – This size varies between 20 to 30 inches in length, 19 to 24 inches in width, and about 7 inches in depth. Large – Large sinks can get up to 50 inches long and vary from 19 to 24 inches wide. They are most often 5 inches in depth.
Round
Round sinks are fairly simple. While they follow the small, medium, and large sizes, all of the sinks are between 5 to 8 inches deep. Sizes are as follows.
Small. Diameter varies from 7 to 10 inches. Medium. Diameter varies from 11 to 15 inches. Large: Diameter varies from 16 to 20 inches.
Vessel
Vessel sinks sit on top of your vanity and can have wider openings. These sinks can also be deeper than traditional top-mounts and under-mounts. Round vessel sinks are typically 14 to 20 inches in diameter and average a depth of 4 to 7 inches. Square and rectangular vessel sinks average 15 to 25 inches in length and 16 to 20 inches in width. These sinks are generally more shallow than other sinks.
Wall-Mount
Wall-mount sinks are designed to save space by attaching directly to a wall and therefore are usually longer than other sinks. These can be 16 to 23 inches in length on the smaller size or 50+ inches on the larger size, 15 to 18 inches in width, and 5 to 8 inches in depth.
Bathroom Sink Size: Depends on Mounting Options
How you plan to have the sink mounted can affect the bathroom sink dimensions. Here is a look at some of the other mounting options and how they can affect the size of your sink. Undermount sinks and top-mount sinks are both good choices for a bathroom. These options can fit almost any size sink, depending on the dimensions of your vanity. By mounting these in or on your vanity, your biggest limitation will be the size of your space. Integrated sinks are actually a part of the countertop itself. The vanity sink dimensions here are also only limited by the space in your room. These sinks usually run in the medium range listed above. Pedestal sinks stand alone and are not a part of your vanity. These sinks are heavier, have no counter space, are often sold in standard sizes (22 to 28 inches long), and are used in smaller bathrooms. Wall-mounted sinks and console sinks are both fantastic options if you are looking for a larger sink. These trough-style sinks, held up by the wall, can be 50 or more inches long. They are great for larger rooms, but there is no vanity attached to them for counter space or storage.
Bathroom Sink Size Guide: Depends on Material
Bathroom sinks can be made from so many different materials, and the material you choose will play a role in the size of the sink. Some of the different materials include ceramic, porcelain, cast iron, natural stone (granite, marble, etc), stainless steel, copper, bronze, wood and bamboo, resin, and glass. While some sinks, such as stainless steel, come in a variety of shapes and sizes, not all of the sinks have such variety. Sinks made of glass or porcelain often run smaller, while sinks made from natural stone can come in a wide array of sizes, both large and small. Here are some average bathroom sink dimensions for these materials.
Ceramic sinks are the most popular in the bathroom and can come in any size needed. Porcelain and cast iron are both heavy materials. While these sinks can be made at almost any size, larger ones will have to be reinforced when installed due to their weight. Wood, bamboo, glass, resin, and natural stone sinks tend to run on the smaller side of standard sink dimensions. While they can be specifically designed for larger rooms, they lean toward the small to medium size sinks listed above. Copper and bronze sinks also tend to run on the smaller side, often with a diameter of 15 inches or less for the round ones and a length of 20 inches for the rectangular ones.
Most bathroom sinks, whichever material they are made of, come in an array of shapes and sizes, so you can find the style that best fits your dream bathroom. Also read: Biggest Trends Pinterest Predicts
