Well, most of the avid readers of this blog are well aware of the importance and benefits of an outdoor kitchen sink and especially if you love to cook delicious food in your yard.

Once you’re done with your tasty homemade foods, the next thing that you need to do is to clean the utensils then and there as bringing them back to your indoor kitchen would definitely be a time-consuming affair.

To deal effectively with such scenarios, an outdoor kitchen sink comes into existence.

You can reap maximum benefits out of an outdoor kitchen sink only if the planning and design have been done properly.

At the same time, you need to keep in mind the drainage that you would be using for your outdoor sink.

The selection of an effective drainage system is very important to prevent any last-minute misadventure.

Let’s have a quick look at some feasible drainage options that you’ve when it comes to installing an outdoor kitchen sink.

Knowing about the various types of drain can make your task easy, and the probability of successfully expediting the entire process would increase multifold.

Drain Types

Mainly, there are three types of drains for outdoor kitchen sinks.

Each one of them has its own pros and cons so you need to choose the one that syncs well with your requirements as well as falls well within your budget.

  • A French drain or dry well
  • Under-sink bucket
  • Sewer or Septic system

French Drain Or Dry Well

As the name suggests, a French Drain or Dry Well is nothing but a pipe whose primary purpose is to accumulates the used or wastewater from your kitchen sink and direct it to a hole full of gravel.

By doing so, water accumulation near your home can be prevented.

Installation of a French Drain is quite easy and will not consume much of your time.

All you need to do is to follow the below steps and you’re done.

  • First and foremost, you need to dig a trench that is 4-6 feet deep and 2 feet wide
  • Once done, you need to put gravel on the pipe
  • Lastly, avoid covering the trench with soil or sand as it may lead to restricted flow of wasterwater through the line

Moreover, for gathering greywater from your sink drainage, you can take the help of a bucket full of gravel.

For proper outflow of the drainage water, a hole needs to be drilled at the bottom of the bucket.

Mainly, there are two types of French drain, that is, traditional, and collector & interceptor French Drain.

The installation process that we’ve discussed so far is for a standard french drain.

A French drain in general is fully covered so that the owner of the yard or the passerby doesn’t get distracted by any means.

On the other hand, a collector & interceptor french drain is an open trench that redirects the water to the channel.

It is mostly preferred in the flooded areas as well as for preventing the surface from becoming damp.

Nonetheless, the construction of a collector & interceptor french drain needs to be followed by the placement of a filter in order to collect debris so that blockage or other related issues can be prevented.

All these can be done in less than 500 dollars so construction of a French drain isn’t a costly affair for sure.

Under-Sink Bucket

Out of all the three outdoor kitchen sink drains, an under-sink bucket is the one that is mostly preferred by our clientele, and trust me, there are numerous reasons for it.

As the name suggests, the entire mechanism revolves around a bucket.

In layman’s terms, all your need is a big bucket that can collect greywater that is released from washing the utensils.

If you’re planning to use an under-sink bucket drainage system, then only one thing you need to keep in mind.

Yes, you guessed it, RIGHT.

Frequent disposal of greywater is very important else it might lead to a foul smell.

And, the good news is, this is a highly affordable system and will cost you somewhere around 10 dollars.

Sewer or Septic System

The third and last one that we’ve is Sewer or Septic System.

If you’re planning to invest in a standard kitchen sink then definitely, you would be needing a sewer system for it to function properly and without any hassle.

Make sure that during the construction and installation process, the sewer system is separated from your home septic system.

In this case, you would be needing a professional plumber to guide you.

He would be responsible for designing the plumbing system for your sink.

Don’t forget to check your local area rules & regulations related to treating & reusing wastewater in order to prevent any last-minute misadventure.

Moreover, if you’re not allowed to treat the greywater then the best thing that you can do is to opt for a sewer system.

In spite of it being the costliest, it is preferred just because of being the safest drainage method.

It will cost you somewhere around 800 dollars.

Important Factors That Determine The Right Type Of Drain

Frankly speaking, there are numerous factors that determine the right type of drain.

However, we would be discussing the two main influencing factors.

Local Authority

Before, starting your project, it is highly recommended that you contact your local authority in order to prevent any last-minute debacle.

Time and again, we’ve emphasized that greywater regulations and codes are essential in determining the type of drain that you should choose for installation purposes.

As per our knowledge and understanding, some regions allow the reuse of greywater while others don’t.

It’s always good to have a separate sewer system for greywater and blackwater.


Of course, budget is an important parameter, and a lot depends upon your budget.

You need to ask yourself, how much you’re willing to spend on an outdoor kitchen sink?

Do you’ve got a limited or abundance of funds?

Most of our clients affirm that they have a shortage of funds and so their budget is limited.

In such a scenario, we ask them to consider installing an under-mount sink.

Neither does it require huge space nor complex installation.

In fact, all you need is a bucket that needs to be emptied on a regular basis to prevent any odor.

On the other hand, the French drain requires a decent budget as well as complex plumbing tools for the installation of the setup.

Outdoor Kitchen Cost

Well, it goes without saying that costing of an outdoor kitchen depends on a variety of factors.

  • Types of materials that you’re gonna use
  • Sink & drain types
  • Add-ons such as a fire pit, refrigerator, shading, fencing, and water foundation
  • Types of flooring
  • Counters
  • Type & range of furniture

From the aforementioned statement, you can understand that the costing has a huge range which depends to a large extent on an individual’s preferences.

Trust me, for the same reason, it wouldn’t be possible for me to tell you the budget involved in building one.

In general, the cost incurred in building a classic outdoor kitchen would be somewhere around $50,000.

However, the average cost of an outdoor kitchen is much lower than that and falls in the $5,000 to $10,000 bracket.

Important Parameters That You Need To Consider Before Constructing An Outdoor Kitchen

Let’s have a quick look at some of the important parameters that you need to consider before constructing an outdoor kitchen.


It goes without saying that space is an important parameter that you can’t afford to ignore.

Moreover, the selection of design and type of outdoor kitchen depends to a large extent on the amount of space that you can allocate to the outdoor kitchen in your yard or otherwise.

If you’re well aware of the availability of space, then you can easily decide on the features that you want in your outdoor kitchen.


Of course, the climate is another important parameter that you need to consider.

By asking simple questions to yourself, you can come to a conclusion.

For example, do I live in a hot or cold climate?

Will the outdoor kitchen sync well with the climatic condition?
