The Ultimate Guide to RV Toilet Paper: Do You Really Need RV-Safe TP?
If you're an RVer, you've probably heard all kinds of rules about toilet paper. Use only expensive RV toilet paper. Never use Charmin. Regular toilet paper will clog your black tank. Household toilet paper will cover your sensors.
So what's actually true?
You do not have to use toilet paper simply because the package says "RV." Many regular household toilet papers can work perfectly well in an RV when you choose the right paper, use a reasonable amount, use plenty of water and manage your black tank correctly.
Do You Really Need Special RV Toilet Paper?
No — not necessarily.
RV-specific toilet paper is generally designed to disperse quickly in water so that it moves easily through RV plumbing and holding tanks.
That's a legitimate benefit.
But it doesn't mean regular toilet paper automatically causes RV black tank problems.
Many household toilet papers are designed for flushability and septic systems and can also separate readily in water. The trick is understanding that not every toilet paper behaves exactly the same way.
RV-Specific Toilet Paper
Designed specifically for RV, marine or portable sanitation systems, with rapid dissolution usually emphasized as a primary feature.
Regular Household Toilet Paper
Can also work well in an RV when the paper breaks apart reasonably well and is used with adequate water and good black tank habits.
What Actually Matters When Choosing RV Toilet Paper?
We think RV owners sometimes put too much emphasis on the words printed on the package and not enough emphasis on what happens inside the tank.
A good toilet paper choice for an RV should:
- Separate or break apart reasonably readily in water
- Flush easily without creating a dense wad of paper
- Be used in reasonable quantities
- Be accompanied by plenty of water
Those last two points are important.
Even a very fast-dissolving toilet paper can contribute to problems if someone uses a huge amount of it while flushing with very little water.
Likewise, a comfortable regular household toilet paper may work perfectly well when you use a sensible amount and give the black tank enough water.
Can You Use Regular Toilet Paper in an RV?
Yes.
We use regular toilet paper ourselves.
And we'll say something that may upset the RV toilet paper industry:
RV toilet paper sucks.
We don't particularly enjoy using it, and we don't believe owning an RV means you have to give up normal toilet paper.
We prefer regular 2-ply toilet paper that is comfortable to use and still breaks apart reasonably well in water.
Best Regular Toilet Paper Options for an RV
There isn't one universally proven "best" household toilet paper for every RV.
Paper formulations can change, different RVers use different amounts of toilet paper, and black tanks vary enormously in shape, plumbing, water levels and dumping habits.
But based on current manufacturer information, published breakdown testing and real-world RV-owner experience, these are some of the regular household papers we'd consider first.
Angel Soft 2-Ply
Our strongest regular 2-ply starting point.
Angel Soft is a widely available household toilet paper. The manufacturer identifies it as septic-safe and designed to break down easily in properly maintained sewer and septic systems.
It has also performed well in independent RV toilet-paper testing and is frequently mentioned by RV owners who use household paper instead of RV-specific tissue.
Charmin Ultra Soft 2-Ply
For RVers who don't want to sacrifice comfort.
Contrary to a common RV myth, Charmin Ultra Soft isn't automatically a bad choice. Charmin currently identifies Ultra Soft as clog-safe and septic-safe.
It has also performed surprisingly well in independent RV breakdown testing, and many RV owners report using it successfully. Because it is a softer, more absorbent paper, use a sensible amount and plenty of water.
Charmin Essentials Soft 2-Ply
A lighter Charmin alternative.
Charmin Essentials Soft is another regular household 2-ply option marketed for clog-safe use. It can be a good middle ground for RVers who want normal household comfort without necessarily choosing one of the plushest papers available.
Kirkland Signature 2-Ply
Mixed real-world results.
Costco currently identifies Kirkland Signature 2-ply bath tissue as septic-safe, and many RV owners report using it successfully.
However, other RVers and homeowners report that some Kirkland papers remain intact or clump longer than other brands. Because real-world experiences are mixed, we would test the specific Kirkland paper you're using rather than assuming that "septic-safe" automatically makes it the best choice for your RV.
What About Scott Toilet Paper?
Scott comes up constantly in RV discussions, but there are several different Scott products and they shouldn't all be lumped together.
Scott Rapid-Dissolving
This is the Scott product specifically made for RVs and boats. Scott says it dissolves significantly faster than its comparison paper and markets it specifically for RV, marine and septic use.
If your priority is rapid breakup rather than household-style comfort, this remains one of the safest conventional RV-specific recommendations.
Scott ComfortPlus
Scott ComfortPlus is a regular household paper and is marketed as clog-free, septic-safe and fast-dissolving.
However, despite its thicker feel, current ComfortPlus products are generally 1-ply — so we wouldn't describe it as our recommended regular 2-ply option.
Scott 1000 also has a long history of use among RV owners, particularly people who prefer a simple 1-ply paper that separates easily.
If comfort matters more to you, however, there's no reason you can't consider a suitable regular 2-ply paper instead.
Best RV-Specific Toilet Paper Options
If you would rather remove the guesswork and buy paper designed specifically for RV waste systems, there are several well-established choices.
Scott Rapid-Dissolving
Specifically designed for RVs and boats and marketed for rapid dissolution, flushability and clog prevention.
Thetford Aqua-Soft
A 2-ply RV and marine toilet paper specifically designed to dissolve rapidly in holding tanks while offering a softer feel than many traditional RV papers.
Camco RV Toilet Tissue
Designed for RV and marine sanitation systems with an emphasis on fast dissolution and compatibility with holding tanks and septic systems.
These products make sense for someone who values the extra margin of confidence that comes from using tissue specifically designed for an RV.
But they aren't your only options.
What About Costco Kirkland Toilet Paper?
This one deserves special attention because Kirkland toilet paper comes up constantly in discussions about RV and septic systems.
Costco currently labels its Kirkland Signature 2-ply bath tissue as septic-safe.
You'll also find plenty of RV owners who say they've used Kirkland for years without a problem.
But you'll find the opposite experience too.
Some people report that Kirkland paper takes longer to separate, forms heavier clumps or has contributed to plumbing or holding-tank problems.
That doesn't prove Kirkland is "bad toilet paper," and it certainly doesn't mean every RV using Kirkland will clog.
It illustrates something much more useful:
Different formulations, quantities, water levels and tank conditions can all change the outcome.
If you're currently using Kirkland and your tank empties cleanly with no problems, there's no reason for us to tell you that you have to stop.
If you're experiencing paper accumulation or poor dumping, however, toilet paper is one of the variables worth testing.
How to Test Your Regular Toilet Paper for RV Use
If you already have a favorite toilet paper, you can do a simple comparison at home.
This is often called the jar test.
- Fill a clear jar or container with water.
- Add a few sheets of the toilet paper you normally use.
- Allow the paper to become completely saturated.
- Gently swirl or shake the container.
- Watch whether the sheets begin separating and breaking into smaller pieces.
If you're comparing two papers, use the same amount of paper, the same amount of water and roughly the same amount of agitation.
The goal isn't to watch the paper magically disappear.
You simply don't want it remaining as one dense, tough wad after it has been thoroughly saturated and agitated.
Does Toilet Paper Have to Completely Dissolve in an RV Black Tank?
No.
This is another place where RV advice can become misleading.
An RV black tank is a temporary holding tank, not a septic digestion system.
You don't need every piece of toilet paper or waste to somehow disappear before you dump.
You need the tank contents to remain sufficiently hydrated and mobile so that waste, water and paper can leave the tank effectively when the dump valve is opened.
That's why looking only at dramatic toilet-paper breakdown demonstrations can miss the bigger picture.
We explore the difference between individual breakdown mechanisms and overall holding-tank performance in our mechanism-based RV holding tank treatment scientific comparison.
Water Matters More Than Many RV Owners Realize
You can choose fantastic toilet paper and still create a black tank problem if you don't use enough water.
Water helps:
- Separate toilet paper
- Keep solid waste hydrated
- Prevent dense accumulation beneath the toilet
- Create better flow when dumping
- Disperse holding tank treatment throughout the tank
One of the biggest mistakes RV owners make is trying to conserve so much black-tank capacity that they barely use any water when flushing.
The Bigger Black Tank Mistake: Leaving the Valve Open
If you're connected to a sewer hookup, don't leave your black tank valve open during normal use.
When the valve stays open, liquid can drain away while toilet paper and solid waste remain behind.
That can create the conditions for waste accumulation or the infamous RV "poop pyramid."
Keep the black valve closed, allow liquid and waste to accumulate, and dump when you have enough tank volume for a strong flow through the sewer hose.
What Should Never Go Down an RV Toilet?
We spend a lot of time debating toilet paper, but some products are much easier to classify.
Generally Appropriate
- Human waste
- Suitable toilet paper
- Plenty of water
Keep These Out
- Baby wipes
- So-called flushable wipes
- Paper towels
- Feminine hygiene products
- Cleaning wipes
- Diapers
- Other materials designed to remain strong when wet
Even if a wipe says "flushable," we'd put it in the trash rather than the RV black tank.
Pro Tips for Avoiding RV Toilet Paper Clogs
- Use plenty of water. This may matter more than switching between two suitable toilet-paper brands.
- Use a reasonable amount of toilet paper. Any paper can become a problem when enough of it is packed together with too little water.
- Keep your black tank valve closed. Open it when you're actually ready to dump.
- Don't obsessively dump a nearly empty black tank. You want enough liquid volume to help move the tank contents out.
- Put water back into the tank after dumping. Don't leave the bottom bone dry during normal use.
- Use a quality holding tank treatment for ongoing maintenance and odor control. A treatment works alongside good water and dumping habits; it doesn't replace them.
- Clean an established dirty tank when necessary. Routine maintenance and deep cleaning aren't the same thing.
If your black tank already has buildup, poor dumping or persistent sensor issues, see our guide to cleaning an RV waste tank and understanding the difference between treatment and deep cleaning.
Our Bottom Line: What Toilet Paper Would We Use?
If you love a particular RV-specific toilet paper and it works for you, there's absolutely nothing wrong with using it.
Scott Rapid-Dissolving and Thetford Aqua-Soft are specifically designed for RV holding systems and remain straightforward choices.
But personally?
We're perfectly comfortable using regular toilet paper in our RV.
For someone looking specifically for a comfortable regular 2-ply household paper, we'd start by considering:
- Angel Soft 2-ply — a strong combination of household comfort, manufacturer-stated easy breakdown and septic compatibility.
- Charmin Ultra Soft 2-ply — a much more realistic RV option than the old myth suggests, particularly for people who prioritize comfort.
- Charmin Essentials Soft 2-ply — another household option worth considering if you prefer something less plush.
We'd put Kirkland Signature in the "test it in your own situation" category because real-world experiences are more mixed.
Frequently Asked Questions About RV Toilet Paper
Do you really need RV toilet paper?
No. RV-specific paper is designed to break apart quickly, but suitable regular household toilet paper can also work well when used with adequate water and proper black tank habits.
Can you use regular 2-ply toilet paper in an RV?
Yes. We use regular 2-ply toilet paper ourselves. Choose a paper that separates reasonably well in water, don't use excessive quantities and flush with plenty of water.
Can you use Charmin in an RV?
Yes, many RVers successfully use Charmin. Charmin currently identifies its toilet paper as clog-safe and septic-safe, and some Charmin products have performed well in independent RV breakdown testing. As with any paper, use a sensible amount and adequate water.
Can you use Angel Soft in an RV?
Angel Soft 2-ply is one of the regular household papers we'd consider. The manufacturer describes it as septic-safe and designed to break down easily in properly maintained sewer and septic systems.
Can you use Kirkland toilet paper in an RV?
You can, and many RV owners report doing so successfully. Costco labels its current 2-ply Kirkland paper septic-safe, but real-world RV experiences are mixed. If you use Kirkland, test how your specific paper separates and pay attention to how well your tank empties.
Is septic-safe toilet paper automatically RV-safe?
Not necessarily. A septic system and an RV holding tank work differently. Septic-safe labeling is useful, but paper breakup, quantity, water use and black tank management all matter.
Does RV toilet paper have to completely dissolve?
No. The goal isn't to make toilet paper disappear. It needs to become sufficiently saturated and separate enough that it can move out of the holding tank with the rest of the waste and water during dumping.
What is the biggest cause of RV toilet paper problems?
Toilet paper is only one variable. Too little water, excessive paper, leaving the black valve open, dumping with very little liquid and existing tank buildup can all contribute to problems.
Good Toilet Paper Habits Are Only Part of a Healthy Black Tank
Use enough water, keep your black tank valve closed until you're ready to dump, and maintain the tank consistently after each dump.
