If your RV bathroom smells like urine, you’re not alone. This is a common issue that many people experience. Unfortunately, there is no one-size-fits-all solution to this problem. However, in this blog post we will discuss some of the most common causes of urine smell in RV bathrooms, and offer some tips on how to fix it!

Why Does My Rv Bathroom Smell Like Urine? If your RV bathroom smells like urine, there are a few possible explanations. The toilet might be backed up, or the smell could be emanating from the carpet, trashcan, or shower curtains. If the toilet is blocked, it might mean that the sewer tank or seals have been damaged/leaked.

If the carpet is stained, it might be time to replace it. And if the trashcan smells, it might be time to clean it out!

The most common cause of urine smell in RV bathrooms is actually from the holding tanks. When waste breaks down, it releases gasses that can stink up your bathroom (and the whole RV!). The best way to combat this problem is by regularly emptying and cleaning your holding tanks. You can also add a Holding Tank Odor Eliminator to your tank to help control the smells.

If you’re still having trouble getting rid of the urine smell in your RV bathroom, there are a few other things you can try.

How to Fix It A Smelly RV Bathroom

If you have a problem with your RV bathroom smelling like urine, there are a few things you can do to try and fix it.


If your RV bathroom smells like urine, it may be because the black tank has dried up. Be sure to refill it with water so that things flow smoothly.

If only dry solids remain, they’ll begin to smell and corrode the tank that contains them.


RV tanks can sometimes dry out, causing unpleasant odors. You can prevent this by filling the tank with water every time you flush the toilet, and also by adding special chemicals to dissolve waste and control smells. Always consult your RV’s owner’s manual before adding any chemical.


When you’re RVing, it’s important to avoid a clog in the beginning by using eco-friendly, RV-grade toilet paper. If a clog does occur, it’s typically quite obvious and can be fixed yourself or by a professional. Remember, a clog can be smelly and costly so it’s best to avoid one in the first place!


Although it’s not a pleasant task, cleaning your holding tank is an essential element of maintaining your waste system’s odor-free.

You can employ somebody to do it for you, or make it into your own personal project; however, the tank needs to be thoroughly cleaned – particularly on its sides where stuck-on substances could reside.

After that, you can use an aroma-enhancing cleaner if needed. If you’re diligent about performing regular maintenance checks on your black tank then it should only need cleaning up a couple times throughout the year!


If you’ve emptied and cleaned your waste holding tank, but are still smelling a sour odor, it’s possible the toilet or flapper needs some good scrubbing.

Make sure to clean them thoroughly as there may be a lingering smell that’s gotten stuck in the system. If your flapper is dirty and not closing correctly, it can allow the smell of your waste tank enter your RV.

Get a rag and soak in warm water to scrub the surface and under the flapper – making sure nothing has been caught. If the flappers isn’t closed properly, you might have to contact an RV maintenance professional for help.


If you’re experiencing a persistent bad smell in your home, and all other options have failed to remedy the situation, it’s possible that there is something wrong with your plumbing.

In this case, you’ll need to consult a professional to take a look and figure out what needs to be repaired.

At the end of the day, the best way to keep your RV bathroom smelling fresh is by being proactive. Whether that means regularly cleaning or adding water to your black tank, a little bit of effort goes a long way in making your RV bathroom odor-free.

Can I put bleach in my RV black tank?

Cleaning your black water storage tank is easiest when you’re connected and have access to both water and sewage. Avoid bleach or antifreeze for your deep clean since these can dry up rubber seals and cause serious damage to your sewage system.

Instead, use RV-specific cleaners that are safe for your tank and pipes.

If you’re not able to hook up to water and sewage, you can clean your black tank with a few buckets of water. Add some RV-safe cleaner to the first bucket and swish it around before dumping it into your black tank. Fill the second bucket with clean water and flush your black tank several times until the water runs clear.

It’s also important to regularly clean your RV bathroom to avoid any build-up of urine or other waste products. Use a mild cleanser on all surfaces, including the toilet, sink, shower, and floors. In addition, be sure to empty out any storage cabinets or drawers where urine or other waste products could be hiding.
