RV Toilet Paper: Scott ComfortPlus vs Scott Rapid Dissolving (Real RV Use)

If you’ve spent any time RVing, boating, or dealing with septic systems, you’ve probably heard the advice: only use RV toilet paper. And if you’ve gone down that rabbit hole, Scott toilet paper almost always comes up.

That’s where the confusion starts.

Scott sells ComfortPlus toilet paper and Rapid Dissolving toilet paper. One is marketed for everyday household use, the other is clearly labeled for RVs, boats, and septic systems.

Are They Actually Different or Just Marketed Differently?

So what’s the real story?

Are these two toilet papers actually different, or is this just clever marketing?

Let’s break it down.

The Short Answer

Scott ComfortPlus and Scott Rapid Dissolving may not be the same exact product, but if they are not, they are extremely similar in material, construction, and performance. For most RVers, the difference comes down to marketing and labeling, not real-world function.

In fact, you’d be hard-pressed to physically tell the difference between the two based on looks, feel, or day-to-day use.

What Both Toilet Papers Have in Common

Before examining the differences, it is helpful to understand what they share.

Both Scott ComfortPlus and Scott Rapid Dissolving are:

• Single-ply toilet paper
• Septic-safe
• Designed to break down faster than typical soft, multi-ply household toilet paper
• Free of lotions, coatings, and binding agents
• Made by the same manufacturer using similar production standards

It’s also worth noting that both Scott ComfortPlus and Scott Rapid Dissolving carry the same “dissolves 10x faster” claim on their packaging. Scott makes this claim for both products, reinforcing that fast breakdown is not unique to the RV-branded version.

In other words, Scott is already telling consumers that ComfortPlus dissolves just as quickly — even though it isn’t marketed specifically for RV use.

This matters because Scott has long been known for producing toilet paper that breaks down more easily than many popular “luxury” brands. That reputation isn’t limited to their RV-branded products.

Scott ComfortPlus: What It’s Really Designed For

Scott ComfortPlus is marketed as a general household toilet paper that balances comfort with fast breakdown.

Key characteristics include:

• Slightly more comfortable than Scott’s most basic 1-ply options
• Strong enough for everyday use
• Designed to dissolve faster than premium household brands
• Safe for septic systems

What Scott doesn’t emphasize on the packaging is RV use. But that doesn’t mean it performs poorly in RV black tanks. In practice, many RVers use it successfully for years.

ComfortPlus exists for people who want something affordable, widely available, and septic-friendly, without stepping up to thick, plush paper. That just happens to align very well with RV needs.

Scott Rapid Dissolving: What’s Different?

Scott Rapid Dissolving toilet paper is explicitly marketed for:

• RVs
• Boats
• Campers
• Septic systems
• Sensitive plumbing

That’s the big distinction.

When you look beyond the packaging, the core traits are very familiar:

• Still single-ply
• Still septic-safe
• Still thin
• Still designed to break down quickly in water

The biggest difference is reassurance. Scott Rapid Dissolving exists to clearly tell RVers, yes, this is safe for your tanks. That peace of mind is what most people are paying for.

Is One Higher Quality Than the Other?

This is where a lot of people expect a dramatic difference. In real-world use, there really isn’t one.

ComfortPlus may feel marginally more comfortable. Rapid Dissolving may feel marginally thinner. But neither is luxury toilet paper, and neither is flimsy junk.

More importantly, real-world water tests, RV forum discussions, and long-term use suggest no meaningful difference in how fast they break down inside a black tank.

If there is a difference, it’s small enough that proper tank management matters far more.

Our Real-World Experience After Nearly 7 Years

This isn’t theoretical for us.

We’ve been using Scott ComfortPlus in our RV for nearly seven years, across different travel styles, climates, and dumping routines. Over that time, it has been consistently trouble-free.

That said, we didn’t just blindly stick with one brand. Like most RVers, we experimented.

What Didn’t Work for Us (and Why)

Scott 1000

Scott 1000 is often recommended because it’s thin and single-ply, but for us, it caused constant black tank sensor issues.

While it does dissolve reasonably well, it had a tendency to cling to tank walls, hang up around sensors, and leave residue behind instead of fully suspending in the tank liquid.

The result was sensors reading dirty or full when the tank wasn’t, even after dumping.

Costco (Kirkland) Toilet Paper

Costco toilet paper was even worse in our RV.

It’s thicker, more absorbent, and designed to hold together — exactly what you don’t want in a black tank. While it’s great in a house, it played absolute hell with our tank sensors.

We experienced false full readings, sensors that stayed dirty after dumps, and a much higher need for tank flushing and cleaning. That was enough to permanently cross it off our RV list.

Why Scott ComfortPlus Worked Better for Sensors

This is where ComfortPlus quietly shines.

In our experience, it breaks apart more completely, stays suspended in water instead of clumping, leaves less residue on tank walls and sensors, and doesn’t “float and cling” the way some papers do.

Since switching back to ComfortPlus and sticking with it, our black tank sensors have been far more reliable. Not perfect — because RV sensors rarely are — but dramatically better than when we used Scott 1000 or Costco paper.

And this wasn’t a short-term test.
This is nearly seven years of consistent use.

What Matters More Than Toilet Paper

It’s worth saying this clearly.

Most black tank problems are caused by:

• Not using enough water
• Letting tanks dry out
• Leaving the black tank valve open
• Poor dumping habits

Toilet paper matters, but tank management matters more. You can clog a tank with RV-branded toilet paper just as easily as household paper if you don’t use enough water or manage the system properly.

Proper black tank management also depends on having a reliable RV sewer hose. A quality hose makes dumping easier, cleaner, and far less stressful. We break down why the Camco RhinoEXTREME has been our go-to choice in our full review here.

Frequently Asked Questions

Is Scott ComfortPlus safe to use in an RV black tank?

Yes. Based on our nearly seven years of real-world RV use, Scott ComfortPlus has proven to be safe in our black tank when used with proper tank management. It breaks down well, stays suspended in water, and has caused fewer sensor issues for us than some other commonly recommended brands.

As with any toilet paper, using plenty of water is key.

Is Scott Rapid Dissolving better than Scott ComfortPlus for RVs?

In our opinion, no. In terms of looks, feel, and real-world performance, we have not seen a meaningful difference between Scott ComfortPlus and Scott Rapid Dissolving. Both behave the same in the black tank.

The primary difference appears to be marketing and RV-specific branding, not performance.

Why does RV toilet paper cost more?

RV toilet paper often costs more because it’s marketed specifically for RVs and boats. That branding provides reassurance and allows manufacturers to charge a premium, even when the paper itself is very similar to septic-safe household options.

You’re often paying for peace of mind, not a dramatically different product.

Can regular household toilet paper damage RV black tanks?

Some can. Thicker, multi-ply, or “ultra-soft” household toilet papers are designed to stay intact, which makes them more likely to clump, stick to tank walls, and foul sensors.

Single-ply, septic-safe papers that break down easily are a better choice for RV use.

Why do black tank sensors give false readings?

Black tank sensors are notorious for false readings. Common causes include toilet paper and waste sticking to the sensors, not using enough water, letting waste dry out in the tank, and leaving the black tank valve open while connected to sewer.

Toilet paper choice plays a role, but water usage and dumping habits matter more.

Is Scott 1000 good for RVs?

Scott 1000 is often recommended because it’s thin and single-ply, but in our experience it caused frequent black tank sensor issues. While it dissolves reasonably well, it tended to cling to sensors and tank walls more than Scott ComfortPlus.

What about Costco (Kirkland) toilet paper in an RV?

Costco toilet paper is thicker and designed to hold together, which makes it a poor choice for RV black tanks. In our RV, it caused persistent sensor issues and required more frequent tank cleaning.

It’s great toilet paper for a house, just not for an RV.

What matters more: toilet paper or tank management?

Tank management, by a wide margin.

Using enough water, keeping the black tank valve closed until dumping, and flushing properly will prevent more problems than switching toilet paper brands alone. Even RV-branded toilet paper can cause issues if the tank isn’t managed correctly.

Final Verdict

Scott ComfortPlus and Scott Rapid Dissolving are not identical SKUs, but in our opinion, in terms of looks, feel, and real-world use, they are the same toilet paper.

After nearly seven years of using Scott ComfortPlus in our RV, and comparing it to other commonly recommended options, we see no meaningful difference between ComfortPlus and Scott Rapid Dissolving in texture, thickness, or performance in the black tank. Both behave the same in day-to-day use.

The real difference appears to be marketing.

Scott Rapid Dissolving is clearly positioned as an RV- and boat-specific product, which provides reassurance for buyers — and also allows Scott to charge more for RV-specific branding. There’s nothing inherently wrong with that. Many RVers are happy to pay extra for peace of mind.

From our perspective, though, this feels less like two fundamentally different toilet papers and more like one product marketed to two different audiences.

For us, Scott ComfortPlus hits the sweet spot of breakdown, sensor friendliness, availability, cost, and long-term consistency. That’s why we’ve used it for nearly seven years — and see no reason to change.
