How you use your outdoor kitchen sink will be the biggest determination on the best way to drain it. Let’s discuss the pros and cons of each way to drain an outdoor sink to determine which is right in your backyard.

Under-Sink Bucket

Using an under the sink bucket is the easiest way to drain an outdoor sink. Install your sink with a simple straight tailpipe that is long enough to fit just inside a container, such as a 5-ballon bucket.

With this method you simply need to empty the bucket before it overflows. You’ll want to empty the bucket before it gets too full since a full bucket of water weighs 40 lbs. and will slosh everywhere.

French Drain & Dry Well

If you don’t want to heft a bucket around every time you use your outdoor kitchen sink, consider installing a french drain into a dry well. This is the method I have used on two different outdoor kitchen set-ups. It’s a simple set-up and cheaper than connecting your sink to your current drainage system.

Installing this method can be simple depending on where your dry well will be located in relation to your sink.

How much you use your outdoor kitchen sink will determine the dry well location. If it is used heavily, you’ll need a location that is away from your house or deck foundation. If you use the sink sparingly, the dry well can be located closer to your sink.

A simple dry well can be a buried bucket that is filled with smaller rocks and has gravel all around and underneath the bucket. Run plumbing lines from your sink to this dry well.

Connecting to the Closest Drain Line

This the best method to drain your outdoor kitchen sink if you plan on using it like an indoor sink. The cost will depend on how far away your current drainage system is located from the outdoor sink, but is more expensive than the other two options.

If you have a full outdoor kitchen including other appliances like a dishwasher, you may be required by code to connect your outdoor sink to your current drainage system. Check with your local building department.
