Differences Between Kitchen Sink and Bathroom Sink

  • Use of The Sink

The kitchen sink is used for washing dishes where it is attached to garbage disposals. As you cook in the kitchen, the sink is often filled with disposals and unwashed dishes. 

You would more likely be looking for a sink that is easier to wash because you need to clean the kitchen sink once every day. 

Also installing a kitchen sink which is larger would be a good option if you have more people in your house.

Bathroom sinks are installed in your bathroom to wash your hands or your face and are likely to be more attractive as you would want a sink more pleasing to the eye when you are in the bathroom. 

These can be more expensive as there are a variety of designs available in the market, which are made from a different range of components.

  • Sink Size

In general, bathroom sinks tend to be smaller than kitchen sinks because they don’t have as much space for soaps and other cleaning supplies on their surface area.

People have also just come to expect smaller sinks in the bathroom because that’s what they have been exposed to. On the other hand, kitchen sinks tend to be much larger and more accommodating for food preparation.

Kitchen Sinks

Kitchen sinks come in four basic sizes: shallow, deep, single bowl, and double bowl. The depths of the bowls range from 10 to 24 inches.

A shallow sink is typically used in a kitchen with limited space. A deep sink will fit larger pots and pans and can be installed without taking up additional space due to the length of the sink.

Decide which size will accommodate your needs before purchasing. Single bowl sinks are most common in homes. They are typically 30 inches long, whereas double bowl sinks are often used for large families with two sinks.

Bathroom Sink

The standard bathroom sink isn’t much different from the kitchen sink. These are typically smaller than the kitchen sink and come in a variety of shapes, including under-mount, wall mount, and free-standing. 

However, there are some things that may be different when choosing the size for your space. For one thing, you’ll have to shop for a smaller-sized basin because the standard bathroom sink is just half as wide as a normal kitchen sink.

An average width for a standard bathroom sink is around 25 to 28 inches. This size also works very well in smaller spaces such as powder rooms. If you want to get a little extra storage space, try installing several small cabinets below your bathroom vanity with shelves.

  • Faucet Size

It is important to know that kitchen and bathroom faucets are not interchangeable. Although, They have the same hole size, which is 1/2 inch for the kitchen and bathroom faucet. 

However, kitchen sinks usually come with a longer center set than bathroom faucets.

Usually, kitchen sinks have a higher faucet, so that you can more easily fill pots and pans with water. On the other hand, bathroom sinks are designed for hand washing and are generally lower, but there is still some variety in those heights too.

  • Drain size

Small kitchen sink drain holes have to be 2 1/2 inches in diameter, and large ones require a 3-inch drain hole. Remember that the drain hole has to be centered on the countertop, and should never be higher than 1 inch up from the bottom of the sink.

On the flip side, most bathrooms have bathroom sinks with drain holes 1.25 inches wide, but a few are 1.5 inches wide and some are 1.625 inches wide.
