Can You Use a Dishwasher Without a Sink?

After a busy day, washing the dishes can be super tiring. Now, at this point, you are probably wondering about installing a dishwasher in your kitchen, right? But what if your kitchen doesn’t have enough space to install a dishwasher near the 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 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 some 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. Usually, most kitchens have the dishwasher on the sink’s right or left side.

But if you don’t have the necessary space, you can also have the dishwasher elsewhere.

Can I Install the Dishwasher Without a Sink by Myself?

The answer to this question depends on your knowledge and expertise. Typically, installing a sink is pretty easy with some essential 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, it will be a bit hard, but not impossible. Furthermore, testing your plumbing skill and saving the plumber’s fee would be a fun challenge. 

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 the dishwasher’s positioning.

These three factors remain the same whether the sink is round or not. 

1. Water Supply

Dishwashers draw loads of water to clean your dishes. So, when using your dishwasher, you also have to ensure a good water supply line to achieve optimal cleaning results.

Now, as we are discussing a scenario where there will be no sink, the water supply can be an issue. So, you must 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 to 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.

  • For example, when the sink is somewhere else at the other end of the kitchen, you’ll need some extra plumbing work behind your kitchen cabinets. Through a new line, the pump will now discharge water into the sink. 
  • 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, keep enough space for optimum movement around the kitchen. Moreover, you must ensure proper drainage and water supply through placement without making the dishwasher sit awkwardly in the corner of the kitchen.  

How Do You Use a Dishwasher After Removing the Sink?

Using a dishwasher with a sink and removing the sink is almost identical. If your dishwasher was previously connected to the sink and you must remove the sink for remodeling or any other reason, reroute the water supply and drainage lines again. 

These days, dishwashers come with some pretty long hoses for 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 quickly, 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 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, cut the regular kitchen drain and install a T connector.

Step 2: 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 a sink, installing a dishwasher island without a sink can make that possible. 

If there is enough space in your kitchen, 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, using a dishwasher without a sink is very much possible.

No one said it would be easy, but you can use it efficiently if you carefully consider the abovementioned factors. Additionally, if you are remodeling your kitchen, ensure you have proper space and connections available by your sink for the dishwasher.

Nothing can beat the convenience and efficiency of a dishwasher that sits right by the sink.
