Whether in a large home or even a small apartment, Kitchens may feature a double bowl sink. These two sinks prove to be beneficial for many reasons.

Kitchens have two sinks for preparation and cleaning. Two sinks allow chefs to separate stations for fresh food and waste disposal.

This article will show you why kitchens have two sinks and their uses.

Why Kitchens Have Two Sinks

Kitchens have two sink stations, mainly for cleaning and cooking.

The cooking sink is used for draining and measuring water levels. Having two sinks can be helpful for those who like to separate cooking and cleaning from each other.

The cleaning sink is used for cleaning dishes, hands, or any other dirty item that needs a quick rinse.

Types Of Double Sinks

Below are the types of sinks that a homeowner can purchase.

Two Sink Stations

The first type of sink station that is often found in the kitchen is the multiple sink station. These are often two different sinks located relatively close to each other.

For instance, if a homeowner has one sink built into the countertop, they may also have another sink built into the kitchen island, as shown below.

This extra sink allows the chef to have two different sinks to prep and formulate the meals.

For example, if you’re cooking something with onion as a side dish and don’t want to get the smell and aroma of other parts of the food, having two sinks can help separate these items.

However, the downside of having two sink stations is that the homeowner will need to have a plumber pipe in another water supply to the second sink.

Two main water supplies must be piped in to have two working sinks.

Double Bowl Sinks

Double bowl sinks are standard in both houses and apartments, as it requires no extra water supply, simply just a different pipe.

Double bowl sinks, shown above, are sink bowls that can be fixed directly to the countertop.

The double sink bowls are great for chefs that want to have two workstations directly next to each other.

Kitchens with double bowls are often used for preparation and cleanup stations.

Preparation means cutting, washing, or disposing of any liquids on the right side of the sink.

This is key, especially if you’re working with any juices, as you don’t want to pour all of these juices over dishes that may be in the sink prior.

The cleanup station will store any dirty dishes from previous cooking sessions or any messy materials used during the cooking process.

For instance, if you’ve used a mixing bowl for the salad and transferred it into a presentation bowl for your guests, you’ll want to put the dirty mixing bowl in the sink.

Especially if you’re a cook who likes to do the dishes after you cook, it may make sense to divide the two workstations to separate clean and dirty.

We always caution the homeowner to check with a plumber to make sure that you can install a double sink before purchasing the products.

Typically, the plumber will need to add a second pipe, funneling to the first pipe for all waste.

We’ve also seen many of our users use the second sink for compost. Put any waste materials you would use for garden compost into this part of the sink and empty it every night.

It’s entirely up to you what you use for this second sink. We believe it makes cooking and preparation have separate stations.
