What Is a Double Bowl Sink?
A double bowl sink has two separate bowls or basins. You can use one side to wash dishes and the other to rinse. Or you can soak pots on one side while using the other for food prep. This design gives you more space and makes chores easier.
Why Size Matters for Double Bowl Sinks
Size is important because it affects how well your sink fits your kitchen. If the sink is too big, it may not fit in your countertop. If it is too small, you might not have enough space for dishes. Also, the size affects how comfortable it is to use the sink every day.

Standard Sizes of Double Bowl Sinks
Most double bowl sinks come in certain standard sizes. Knowing these sizes helps you choose the right sink for your space.
| Sink Size (Width) | Bowl Size (Each Bowl) | Depth |
|---|---|---|
| 30 inches | 14-15 inches wide | 7-9 inches deep |
| 33 inches | 15-16 inches wide | 8-10 inches deep |
| 36 inches | 16-18 inches wide | 8-10 inches deep |
| 39 inches | 18-20 inches wide | 9-10 inches deep |
Note: The width is the total sink width from left to right. The bowl size is the size of each basin. Depth is how deep the sink is from top to bottom.
How Big Can a Double Bowl Sink Get?
Double bowl sinks can get quite large. The biggest models can be 39 to 42 inches wide. That means each bowl can be about 20 inches wide. The depth can be up to 10 inches or more. These large sinks are good for big kitchens or people who cook a lot.
But remember, your countertop space limits how big the sink can be. You must measure your kitchen counter before buying.
Common Double Bowl Sink Shapes
Double bowl sinks come in different shapes. The shape affects size and how you use the sink.
- Equal Bowl Sinks: Both bowls are the same size. Good for balanced work.
- Unequal Bowl Sinks: One bowl is bigger than the other. The big bowl is for washing pots, the smaller for rinsing.
- Offset Double Bowls: Bowls are not side by side but one is set back. Saves counter space.
Depth of Double Bowl Sinks
Depth is how deep the bowls are. This affects how much water the sink can hold. It also affects comfort. A deep sink can hold big pots and pans. But it might be harder to reach the bottom.
Standard depths are usually between 7 and 10 inches. Some sinks can be deeper, up to 12 inches. Choose a depth that fits your needs and comfort.
Measuring Your Space for a Double Bowl Sink
Before buying, measure your kitchen space carefully. Follow these steps:
- Measure the width of your countertop where the sink will go.
- Measure the depth of the countertop (front to back).
- Check the cabinet size under the counter. It needs to fit the sink and plumbing.
- Leave some space around the sink for installation and ease of use.
If you don’t measure right, the sink may not fit well. It is better to know your space before shopping.
How to Choose the Right Size Double Bowl Sink
Choosing the right size depends on your kitchen and how you use it.
- Small Kitchens: Choose a smaller sink, around 30 inches wide. This saves space.
- Medium Kitchens: A 33 to 36-inch sink fits well and offers good bowl size.
- Large Kitchens: You can choose a big sink, 39 inches or more wide.
- Cooking Style: If you cook a lot, a bigger sink helps with washing large pots.
- Household Size: Bigger families might want bigger sinks to handle more dishes.
Materials Affect Sink Size Options
Material also changes sink size choices. Common materials include stainless steel, porcelain, and granite composite.
- Stainless Steel: Light and strong. Comes in many sizes.
- Porcelain: Heavier and can chip. Usually smaller sizes.
- Granite Composite: Durable and heavy. Often found in medium to large sizes.
Installation Types and Size Limits
How a sink is installed also limits size.
- Top Mount (Drop-In): Sink drops into a hole in the countertop. Size depends on the hole size.
- Undermount: Sink is fixed under the countertop. Usually needs a strong countertop and space under the sink.
- Farmhouse (Apron Front): Sink front sticks out past the counter. Needs more space.
Each type fits certain sizes best. Check installation type before buying.
