When it comes to installing or replacing a garbage disposal in a double sink, knowing which side to place it on can be a bit confusing. The side you choose can impact the functionality and accessibility of your sink. Let's dive into this topic to help you make an informed decision.
Understanding Your Sink Configuration
Before we delve into which side to place your garbage disposal, it's crucial to understand the two common double sink configurations:
- Side-by-Side Sinks: In this layout, both sinks are placed next to each other, with the drain pipes running parallel to the wall.
- Offset Sinks: In this configuration, one sink is placed slightly higher than the other, with the drain pipes running at different heights.
Which Side for Side-by-Side Sinks?
For side-by-side sinks, the most common and practical placement for the garbage disposal is under the left sink. This is due to a few reasons:

- The left side is typically where the dishwasher is located, making it convenient to scrape food directly from the dishwasher into the garbage disposal.
- Most people are right-handed, so placing the garbage disposal on the left allows for easier access and operation with the dominant hand.
- Plumbing codes in some areas may require the garbage disposal to be installed on the left side to prevent cross-contamination between the sinks.
Exceptions to the Rule
While the left side is generally the best choice, there are a few exceptions:
- If your kitchen layout is left-handed, you might find it more convenient to place the garbage disposal on the right side.
- If your dishwasher is located on the right side, it might be more practical to place the garbage disposal there as well.
Offset Sinks: A Different Approach
For offset sinks, the decision can be a bit more complex. Here are a few factors to consider:
- The lower sink is typically used for washing hands and rinsing dishes, so placing the garbage disposal under this sink might be more convenient.
- However, the higher sink is often used for food preparation, making it convenient to have the garbage disposal under this sink for scrapping food directly into it.
In this case, it might come down to personal preference and how you use your sinks on a daily basis.

Installation Considerations
Regardless of which side you choose, there are a few installation considerations to keep in mind:
- Ensure there is enough space under the sink for the garbage disposal and for you to access it for maintenance.
- Check that the plumbing and electrical connections can reach the chosen side.
- Consider the height of the garbage disposal and ensure it won't interfere with the cabinet doors or drawers.
If you're unsure about any aspect of the installation, it's always a good idea to consult with a professional plumber or contractor.
Final Thoughts
Placing your garbage disposal on the correct side of your double sink can greatly improve the functionality and convenience of your kitchen. By understanding your sink configuration and considering your personal needs, you can make an informed decision that will serve you well for years to come.
