Can You Use a Dishwasher Without a Sink?


A dishwasher can be a very handy part of every kitchen. After a busy day, it can be super tiring to wash those dishes to clean those dishes. If you have a dishwasher installed at home, you don’t have to deal with this problem anymore.

Now, at this point, you are probably wondering about installing a dishwasher in your kitchen, right? Well, how about your kitchen doesn’t have enough space to install a dishwasher? If you don’t know already, a dishwasher typically needs a sink to draw water and then later dispose of all the dirty waters from cleaning. 

So, if you still install the dishwasher somewhere else without a sink, will you be able to use it? I think that’s a question many homeowners like you have in mind, and in this article, I will be discussing whether it’s possible or not. 

Can You Use a Dishwasher Without a Sink?

You can use a dishwasher without a sink nearby, but installing it might be a bit harder than installing it with a sink. The sinks both supply and dispose of all the water from the dishwasher, so it would be a little tricky but doable. 

I mean just look around you. Not all homeowners have re-planned spaces left to install dishwashers later. So, if your kitchen doesn’t have the space, there is no need to be concerned here. If you move forward with a little bit of planning and our guidelines, you can easily use a dishwasher in your kitchen without a sink. 

Can You Have a Dishwasher Not Near the Sink?

Having the dishwasher near the sink makes the installation process a lot easier. Normally, you would notice most kitchens either have the dishwasher on the right or the left side of the sink. But if you don’t have the necessary space, you can also have the dishwasher somewhere else.

Can I Install the Dishwasher Without a Sink by Myself?

The answer to this question actually depends on your knowledge and expertise on this matter. Typically, installing a sink is pretty easy with some basic plumbing tools in hand. Many homeowners out there are doing it all by themselves too. However, most people decide to call a plumber to ensure everything goes okay.

But this time, as the sink is out of the scene now, it will be a bit hard, but not impossible. Furthermore, it would be a fun challenge to test your plumbing skill alongside saving the plumber’s fee

What Should You Consider Before Using a Dishwasher Without a Sink?

Now that you know you can use a dishwasher without a sink let’s look at some factors you should keep in mind to make it possible. To use a sink in your kitchen, you have to ensure three things, the water supply, drainage and lastly, the positioning of the dishwasher. Whether the sink is round or not, these three factors remain the same. 

1. Water supply

Dishwashers draw loads of water to clean your dishes. So, when you’re using your dishwasher, you also have to ensure a good water supply line to achieve optimal cleaning results. Now, as we are talking about a scenario where there will be no sink, the water supply can be an issue. So, you have to ensure an alternative water source, at least a cold one, to ensure the dishwasher gets enough water. 

2. Drainage system

I think ensuring proper drainage is the trickiest part when you are using a dishwasher without a sink. Why? Let me explain. When you have a sink nearby, draining is pretty easy. 

All you have to do is connect the dishwasher’s drainages with the sink, which is already connected to the central drainage system of your home. But how will you manage the drainage when the sink isn’t around? There are two ways you can solve the issue. 

  1. When the sink is somewhere else, for example, at the other end of the kitchen, you’ll need some extra plumbing work behind your kitchen cabinets. Through a new line, water will now be discharged into the sink by the pump. 
  2. Another thing you can do is line up the drainage through your basement if you have any. Going under the flow won’t be easy, but it can be effective if you have no other options. 

3. Proper placement

The last thing you should consider here is the placement of the dishwasher. As you will be using the dishwasher without the sink, the dishwasher placement will likely be in an odd location far from the sink. Moreover, to manage the water supply and drainage, you also have to move the dishwasher around. 

So, no matter what you do, just keep enough space around for optimum movement around the kitchen. Moreover, you have to ensure proper drainage and water supply through placement without making the dishwasher sit awkwardly in a corner in the kitchen.  

How Do You Use a Dishwasher After Removing the Sink?

Using a dishwasher with a sink and removing the sink are almost the same. If your dishwasher was previously connected to the sink and now you have to remove the sink for remodeling or any other reason, just reroute the water supply line and the drainage line again. 

Dishwashers these days come with some pretty long hoses for both drainage and water line. With attachments, these hoses can go up to 12’. So you can easily redirect these lines following the methods discussed earlier and use the dishwasher easily even after removing the sink.

How To Drain Dishwasher Not Near the Sink?

Now that the sink is not nearby, it can be confusing how you are supposed to drain all the water from cleaning, right? Well, there is no need to worry there as the dishwashers available on today’s market can send the water away easily no matter the distance from the sink. 

If you look closely at a dishwasher and its specification, you’ll notice that the dishwasher equips a discharge pump that helps to dispose of all the water. And the specification also states the maximum distance at which the pump can discharge water effectively.

So, if you got the specifications right, here is how you can drain the dishwasher not near the sink by taking it into the basement.  

  • Step 1: First, you have to cut the regular kitchen drain and install a T connector there.
  • Step 2: Then, before you draw a drainage line, install a trap near the dishwasher to stop any bad odor from coming through.  
  • Step 3: After the trap installation, get an ABS or copper pipe, whatever you have available, and connect the pipe to the sink drain further away with a T connector. You can try this same solution for the water supply line too.

Install Dishwasher Island Without Sink

Kitchen Island doesn’t always have to have a sink on it. So, if you want to use a dishwasher without the sink, installing a dishwasher island without a sink can make that possible. 

If there is enough space in your kitchen, just install a dishwasher island without a sink, and it’ll be a lot easier to hide the new pipes and connections you’ll need to use the dishwasher without a sink around. 


As you can see, it’s very much possible to use a dishwasher without a sink. No one said it would be easy, but you can use it pretty efficiently if you carefully consider the factors I mentioned above. Additionally, if you are remodeling your kitchen, ensure you have proper space and connections available by your sink for the dishwasher. At the end of the day, nothing can beat the convenience and efficiency of a dishwasher that sits right by the sink.
