Configuration and Use

You probably use your sink more than anything else in the kitchen, so the size, shape, and number of bowls you choose is ultimately dictated by how you intend to use it. If you do a lot of cooking and washing up, having a double sink can have advantages. For example, if you have one bowl for the disposal and one for soaking, you could still access the disposal with a double sink while you soak - in a single bowl, you would have to choose. Likewise, it’s possible to separate heavier items from more delicate items when using a double sink, while in a single sink delicate items may become broken more easily. Having two sinks also allows you to keep one side clean while you use another for items that may harbor bacteria such as raw meats.

While the ideal size for a sink is roughly 21-inches for the main sink, with a second sink of 15-inches, this size may not always be possible for every kitchen. Single bowl sinks are often available in the same overall size as double sinks but have the added benefit of being available in a range of smaller sizes as well. While a double sink needs to be large enough to accommodate two bowls, single bowl sinks can take up relatively little space. So, for smaller kitchens or ones with a corner sink installation, a single bowl sink, such as the popular D-shape bowl, could be a better fit. Finally, if your cabinetry uses a small sink base cabinet, you may find that you have more options for sink styles when selecting a single bowl because double bowl sinks require a larger base cabinet. In new construction, it’s possible to upgrade your cabinet, but if you’re only replacing the countertop and sink, you are more limited by what cabinet size you already have.

Double bowl sinks also come in a range of sizes and configurations, from two bowls of equal size and shape to a large compartment with a smaller side compartment. This provides versatility in the way you use your sink. It is difficult, however, to soak a large pan in a double bowl sink because of the partition between the two bowls. Therefore, single bowl sinks are more useful for things like washing large pots or babies, while a double bowl sink has more options for how to use the sink.

Installation

As far as the installation of the sink is concerned, there is little difference between a single and double bowl. Both sinks are held in place with epoxy ² and sink clips. A large C-clamp will hold the sink to the counter while the epoxy ² dries. The difference in the installation is when it is time to connect the plumbing.

Because a single bowl sink has only one drain, the installation is faster, easier, and cheaper. Placement of the faucet is also easier because there is only one bowl requiring water.

Double bowl sinks have two drains, which need to connect to one another before entering the final waste trap. One side of the sink may have a garbage disposal, while the other does not, which increases the difficulty. In addition, having a double bowl sink raises the question of where the faucet will be placed. If both sides of the sink will be used for washing, the faucet needs to be located so that it can fill both sides.

Combining Your Sink with a Dishwasher

Dishwashers are common additions to many kitchens and are installed near the sink for easy access. Either sink works with a dishwasher, although because you will not be using the sink for dishes, a single basin sink may be more useful for cleaning items too large for the dishwasher. Neither sink affects the use of the dishwasher, however.

Maintenance

Your sink’s maintenance will be dictated by the material. Granite or quartz composite sinks require no additional maintenance. However, some sinks, which show wear more easily like solid surface or copper, may show wear marks on the partition between the two sinks of a double basin if you lean things like baking sheets against the top edge. This may require more cleaning to prevent stains.
