The location of a kitchen sink drain depends on the layout of the sink and the plumbing system in your home. In most cases, the drain is located underneath the sink, near the back of the cabinet. It is typically connected to the sink through a pipe that runs through the bottom of the sink. The drain pipe is usually connected to the main sewage line or septic system, which carries the wastewater and solid waste away from home.
Center vs. Side vs. Rear Kitchen Sink Drain Comparison
A kitchen sink can have either a center drain or a side drain. The drain can also attach to the back side of the sink. The drain’s location can affect the sink’s overall appearance and functionality.
Table Comparison Between Center vs. Side vs. Rear Kitchen Sink
| Feature | Center Drain | Side Drain | Rear Drain |
|---|---|---|---|
| Space Efficiency: | Moderate, may interfere with under-sink storage. | Better, and allows for slightly more storage space. | Best maximizes under-sink storage space. |
| Ease of Installation: | Easier, more traditional placement. | Moderate, depending on sink design and cabinet configuration. | Slightly more complex, and requires precise alignment with plumbing. |
| Drainage Efficiency: | Good, but can be affected by bottom flatness. | Good, similar to the center but may allow for better water flow on one side. | Best, allows for faster drainage due to the slope towards the back. |
| Under-sink Storage: | Less, due to the central placement of the drain. | Moderate, slightly more space than the center. | Maximum, since the plumbing is pushed to the back. |

Center Kitchen Sink Drain
A center drain sink has a drain that is located in the middle of the sink basin. This type of sink is often used in under-mount or top-mount configurations, where the sink is mounted under or on top of a countertop. Center drain sinks tend to have a more symmetrical and balanced appearance, and they can be easier to clean because debris is less likely to accumulate in the corners of the sink.
-
Side drain sink
A side drain sink has a drain that is located on one side of the sink basin. This type of sink is often used in drop-in or self-rimming configurations, where the sink is dropped into a hole in the countertop. Side drain sinks tend to have a more asymmetrical appearance, and they may be more difficult to clean because debris can accumulate in the corners of the sink.
-
Rear drain sink
A rear drain sink is a type of kitchen sink with a drain at the back of the sink basin. It does not take up any space in the middle of the sink basin. This can allow for more usable space in the sink, making washing large pots and pans easier. Rear drain sinks can also have a more symmetrical and balanced appearance, which can be aesthetically pleasing. Because the drain is located at the back of the sink, accessing and cleaning may be more challenging. Rear drain sinks may also be more expensive and harder to find than traditional center drain sinks.
All drain sinks have their own advantages and disadvantages, and the best choice for your kitchen will depend on the layout of your sink area.

Remove Old Drain:
Once you have all of your supplies ready to go, you need to remove the old drain. This part can be tricky, so make sure to use caution when removing it so as not to damage any pipes or fittings.
Install Strainer:
After removing the old drain, install the new basket strainer in its place. Make sure it is properly secured with washers and screws before moving on to the next step.
Connect P-Trap Assembly:
Now that the basket strainer is installed connect the P-trap assembly using PVC pipes and fittings if needed. This part can be a bit confusing, so refer back to your instructions if required while doing this step.
Secure Pipes:
Once all of your pipes are securely connected with the P-trap assembly, secure them together using plumber putty around each joint and tighten with pliers if necessary.
Test It Out:
The final step is testing out your new kitchen sink drain! Fill up your sink with some water, let it run down into the drain, and see if everything works properly – no leaks or weird noises! If there are any issues at this point, be sure to address them before using your kitchen sink!
Frequently Asked Questions
Q: Does the position of the drain affect how well a kitchen sink drains water?
A: Yes, the position of the drain can affect drainage efficiency. A rear-positioned drain can help maximize usable space under the sink, while a center drain may offer more straightforward plumbing connections.
Q: Are there any advantages to a side-positioned drain in a kitchen sink?
A: A side-positioned drain is beneficial if you often use large pans or trays in the sink. It provides more unobstructed space for cleaning larger items.
Q: How does the drain position impact the installation process of a kitchen sink?
A: The installation complexity can vary based on the drain position. For example, a rear drain might require more intricate plumbing adjustments compared to a centrally located drain.
Q: Is there a difference in cost between rear, center, and side-positioned drains?
A: The cost difference is usually minimal and depends more on the sink’s material and quality than the drain position. However, the plumbing costs might vary slightly.
Q: Can I switch the drain position in my existing sink from center to rear?
A: Modifying the drain position in an existing sink is challenging and often not feasible. It is usually better to choose a new sink with the desired drain position.
Q: Do rear-positioned drains have any disadvantages compared to central ones?
A: Rear-positioned drains might complicate plumbing in some kitchen layouts and may limit the space for under-sink storage due to the plumbing configuration.
Q: Are there any ergonomic considerations in choosing the drain position?
A: Yes, ergonomically, a rear or side drain can reduce the need to reach over dishes to access the drain, potentially reducing strain on the back.
