Kitchen sinks are far and away the most important component found in kitchens anywhere in the world. The reason is simple to understand when you think how important water is in both the preparation and cleanup of food. The basic function of a kitchen sink is to serve as a waterproof receptacle for liquids and mushy solid foods of any type.

Kitchen sinks differ from bathroom sinks in both size and sometimes the material that makes up the sink. A kitchen sink needs to be robust in size so it can easily accommodate large bowls, pots and pans, and any other utensil that one might use to prepare food.

The kitchen sink must also be able to withstand the abuse these large, heavy objects impart on a sink. Most people know that smaller objects like glasses, plates and silverware can create scratches and nicks in kitchen sinks. Larger objects can do serious damage to sinks that are not made to withstand a certain amount of daily wear and tear. For this reason, heavy-gauge stainless-steel kitchen sinks are a favorite. Porcelain-coated cast iron should be considered if you want a vintage kitchen sink.

A bathroom sink can be smaller and made from vitreous china, since it is not exposed to the wear and tear of a kitchen sink. Cast-iron sinks are frequently used in bathrooms, as are porcelain-coated steel sinks.

Ever-changing trends put pressure on kitchen-sink manufacturers to explore other materials for kitchen sinks. Solid plastic is still available, and these sinks can be bonded to solid-surface countertops so the sink looks to be sculpted from one solid piece of plastic. Granite kitchen sinks, and those made from marble and other hard stones, make for a dramatic look.

Copper, brass and any other corrosion-resistant metal can be used to form a kitchen sink. Copper and any copper alloy offer a unique characteristic not found in any other sink material. Copper kitchen sinks have a built-in natural chemical mechanism that kills many bacteria and viruses within minutes of contact. This hidden quality can help keep you and your family healthy.

When looking at kitchen sinks, pay attention to the depth of the bowl. Not all sinks are created equal. Many kitchen sinks offer extra depth to make cleaning large bowls and pots a very easy job.

If your kitchen is large enough to handle two sinks, give serious consideration to this possibility. Many kitchen sinks are available in a double or side-by-side configuration, but these can only be used by one person. If you have two separate sinks in two different locations in a kitchen, two people can work independently without getting in each other's way.

The mounting method of kitchen sinks is also an option. The bowl can be placed under the countertop so that water and food can be pushed into the sink like water flowing over a waterfall. A second design is an overmount lip where the top of the sink is higher than the surrounding countertop. Over and undermount kitchen sinks are available in a wide variety of colors, sizes and material choices.
