Unlike an outdoor kitchen sink, an RV bathroom sink needs to be handled with utter care.

Failing to do so can do more harm than good.

To be honest, you need to have a close eye on your recreational vehicle sink so that drain clogging could be prevented.

But, what if, you found that your RV bathroom sink is clogged during the regular check.

Well, stay with us, as we would be discussing the nuts and bolts of how to unclog an RV bathroom sink in order to help you clear your doubts and do the needful in a hassle-free manner.

Does it make sense?

Can you guess the main reasons for the clogging of an RV bathroom sink?

As far as I know, specks of dirt, debris, food particles, and most importantly, hair residue are some of the reasons for your RV bathroom sink getting clogged.

Since the aforementioned devils will block the free flow of water so it will start smelling foul.

Unfortunately, the RV interior is comparatively less spacious making the foul smell unbearable and intolerable.

If you’re facing something similar then the best thing that you can do is to call a plumber.

However, if you’ve got prior experience in plumbing or you’re a DIYer then you can definitely resolve the issue on your own.

Trust me, you can unclog your RV bathroom sink on your own but for that, you would be needing certain items that we would be discussing in a while.

So, without any further ado, let’s begin…

What Are the Reasons For an RV Sink Clogging?

Though there could be numerous reasons behind the clogging of an RV bathroom sink.

However, the major ones are specks of dirt, food particles, debris, hair, etc.

Moreover, you should also be aware of the fact that, unlike regular houses, an RV has storage tanks with limited space for sink wastage that needs to be cleaned on a timely basis.

The RV’s tank is popularly known as galley tank and when it is full the complete draining of water becomes difficult.

It’s common to see water remaining on your RV bathroom sink when the tank is full.

Whenever you see water remaining in the RV sink, the first thing you need to check is whether the galley tank is full or NOT.

If it is empty then the sole reason for blockage would be clogging and nothing else.

Moving further, I would be walking you through various ways of dealing with an RV bathroom sink clogging in an effective way.

Methods Involved in Unclogging of an RV’s Bathroom & Kitchen Sink

All the methods involved in unclogging of an RV’s bathroom sink that we’re gonna discuss in a while are time tested and have been applied by our clients.

Apart from a few, the rest of the feedback is positive and promising.

So, we decided to introduce these methods to a wider range of audiences through

The biggest problem with an RV bathroom sink clogging is the foul smell associated with it.


It’s a humble request to have the below-mentioned items handy with you in order to prevent any last-minute misadventure.

  • Baking soda and vinegar
  • Baking soda and salt
  • Hot Water
  • Sink plungers
  • Drain snakes

In general, a single method will do the trick for you.

But, at the same time, if the clogging is nasty then you might need to expedite more than one step in order to reap maximum benefits.

Baking Soda & Vinegar

You need to prepare a mixture of baking soda and vinegar.

Mix one-third cup of baking soda and vinegar to prepare a semi-liquid paste.

Pour the mixture in your RV bathroom sink and give it some time to get settled.

The mixture does a tremendous job in getting rid of specks of dirt, food particles, debris from the sink.

You need to flush the RV sink with lukewarm water.

Pour the hot/warm water only after the mixture of baking soda and vinegar has settled properly.

In general, we ask our clients to wait for at least an hour before pouring the hot water into the sink for cleaning purposes.

Pour water into the sink and check whether it’s flowing properly or NOT.

In case, water isn’t flowing properly then move to the NEXT step.

Use Hot Water

The use of hot water makes grime and other factors leading to blockage shrinking and getting out of the drain.

All you need to do is to boil two to three pots of hot water and then pour them into your RV’s bathroom sink.

Perform this step only if you’re sure that you can leave the sink for a couple of hours or even more without using it.

The best time to expedite this step is night.

Leave the sink as it is after pouring hot water at night.

In the morning, again pour a pot of hot water and then open your tap and see whether the drain is cleared or NOT.

Try Sink Pluger

A sink plunger is a quick, easy, and less time-consuming method to clear a bathroom sink.

Don’t confuse a toilet plunger with a sink plunger and if you’re using the former in the place of the latter then things can turn out to be weird for sure.

All you need to do is to place your sink plunger on the sink’s drain and push it down in such a way that air is removed from its cup and suction is generated.

At least, wait for a minute or so before removing the plunger.

Lastly, pour water on your sink and check whether it’s draining properly or NOT.

Baking Soda, Salt, and Hot Water

Prepare a paste of baking soda and salt by mixing a half cup of baking soda and salt in a bowl.

Pour the mixture into your RV bathroom sink and wait for at least 30 minutes.

Pour a couple of pots of hot water into the sink and you’re done.

Simple, quick, and newbie-friendly method.

We’ve found this method to be highly effective when it comes to unclogging an RV bathroom sink.

Use Drain Snakes

So, here I come with my favorite method for unclogging an RV bathroom sink.

It is popularly known as a drain auger and has given mind-boggling results to us in the past.

And, the best part is, a drain auger can easily and quickly fit into the drain, thanks to its spiral shape and 0.25 inches thickness.

All you need to do is to shove the snake into the drain till the time you witness a large chunk of blockage in the form of debris, specks of dirt, hair, debris, or whatnot.

With the help of a drain, you need to push the obstruction out of the draining pipe.

Remove the auger only when you’re sure that all the obstruction and blockage have been taken care of.

In order to ensure the drain is fully unblocked you need to pour hot water into the sink for at least 5 minutes.

Preventing RV Bathroom & Kitchen Sink Blockage

Prevention is always better than cure, isn’t it?

If you’re not finding an effective way to prevent sink blockage then it can turn out to be repetitive with I believe you’ll never want, right?

  • Make sure that all the food particles have been removed from the dishes and utensils before washing them into your RV bathroom sink
  • In order to prevent solid particles from entering your RV bathroom sink insert a sink strainer on the drain
  • Make a habit of frequently cleaning and emptying the galley tank

By following the aforementioned simple and effective steps, you would be able to prevent your RV bathroom sink from getting blocked.
