Best Toilet Paper For Septic Tanks – Complete 2021 Round-up

| Last Updated: October 23, 2022

Many toilet paper brands say “septic-safe” on the packaging, but it is difficult to know what toilet paper is best for your septic system.

When toilet paper travels to the septic tank, it either dissolves or contributes to the sludge that rests at the bottom of the tank. The build-up of sludge is the reason septic tanks need pumping every few months.

Sticking with toilet paper that dissolves easily in the tank will mean having to pump out the system less frequently saving time, money, and effort.

Here is the breakdown of the top toilet papers for septic tanks with a list of their pros and cons.

What To Look For in Toilet Paper For a Septic Tank

It is important to keep the septic tank in good condition, but that doesn’t mean sacrificing comfort and effectiveness. When looking for the right paper for a septic tank, consider aspects like texture, dissolvability, and chemicals used in the product.

Why Are These Important?

Septic tanks act as a balanced ecosystem. Certain aspects of the toilet paper used can throw off this ecosystem, causing issues with the tank. That is why it is necessary to consider these factors when choosing the best toilet paper for a septic tank.


A toilet paper should be soft to the touch yet firm and pliable. A scratchy toilet paper or one that breaks too easily makes for an uncomfortable bathroom experience.

For this factor, it is best to find a happy medium between the ultra-plush, super luxurious toilet papers and the scratchy, recycled papers that will be unpleasant to use.

Those extra plush toilet papers are comfortable but can wreak havoc on your septic tank in the long run. The long, strong fibers of luxury toilet paper will not break down quickly enough and causes problems with the tank.


The best toilet paper for septic tanks dissolves easily and won’t linger in the tank too long. A paper that won’t dissolve will add to the sludge at the bottom of the tank.

Biodegradable and recycled toilet papers break down much quicker than other toilet papers, making them the obvious choice for those with septic tanks.

Technically, all toilet paper is biodegradable, but some will break down significantly better. Thicker, non-recycled toilet paper will not only take longer to break down in the tank, but they will also take up more space.


It may surprise some, but most toilet papers contain chemicals like bleach and chlorine. Septic tanks have anaerobic bacteria that help break down waste and keep the tank running.

Many toilet papers contain a lot of bleach which is how they get their bright, white color. These chemicals disrupt the bacterial process in the tank, halting decomposition. To avoid this, opt for toilet papers treated with little chemicals. Biodegradable and recycled toilet papers typically contain fewer of these chemicals.

Key Terms to Know

To help compare products in this review, we have included a few key specifications for each. Here is a quick summary of what they mean.

  • Ply Rating: The number of layers per sheet of toilet paper.

  • Certifications: Any independent certifications the toilet paper obtained.

  • Other Special Features: This can refer to how the paper is sourced, what it is made from, or any other notable features.  

  • Type: The category the toilet paper falls into. This includes biodegradable, recycled, and septic-safe types.

Scott’s Rapid-Dissolving Tissue Paper is one of the most popular septic-safe papers on the market because it has a few downsides. The toilet paper is soft and slightly cushioned, so it is a significant step up from the scratchy newspaper.

RV and boat owners rave about this paper in their reviews, stating it is far better than any other toilet paper they have tried. If this paper works for boat and RV use, it is more than safe for a septic tank that can handle more.

This bio-friendly toilet paper is made from plant fibers and utilizes a unique ripple effect for extra comfort. Using plant fibers instead of cutting down trees is better for the environment and offers an excellent alternative to chopping down trees.

The ripple design makes the paper thicker, even though it is only 2-ply, and helps it clean better than standard toilet papers. This design makes the toilet paper feel three times and thicker and twice as absorbent than the average tissue on the market.

Customers love that this paper feels like a cushioned tissue without risking the well-being of their septic system. And people love how eco-friendly it is!

Everyone who uses this toilet paper raves about how strong it is and how comfortable it is to use. The softness combined with the durability makes this tissue great for use in the bathroom. Because it absorbs more, you can use less on every trip to the bathroom.

In the long run, this can be good for your septic system because using less toilet paper in the bathroom means less paper ends up in the tank. But experts state this toilet paper has poor dissolvability, which can be cancer for a septic system. 

These rolls are extra-large to last a long time giving you the most bang for your buck. Charmin claims that one roll of this toilet paper is equivalent to five rolls of another brand, which is a massive increase in thickness.

Purchasing these larger rolls will save money on toilet paper if used sparingly. But it can wind up costing you more in septic tank pumps throughout the year.

Bottom Line

The biggest benefit of this toilet paper is its absorbency. It is still strong when wet and won’t fall apart in your hands. However, because of its strong fibers, it does not dissolve quickly in the septic tank. It is septic-safe, but where you save some money, you lose some of the technology that is best for septic tanks.


Strong when wet

Extremely absorbent

Comes in 24 roll pack

Clog-safe and septic-safe

Very soft and gentle on skin


Thick rolls

Does not dissolve well

What is Septic Safe Toilet Paper?

Septic-safe toilet paper will dissolve easily in the tank and not throw off the chemical balance in the tank.

Extremely plush toilet paper, like 3-ply, will be too tough to dissolve in the water of the septic tank. Paper with fewer layers will dissolve easier, making them a better option for those with septic tanks.

The chemicals in toilet paper will prevent your septic tank from efficiently breaking down waste and other substances. Bleach, chlorine, and other harsh solvents stop the bacteria from doing their job resulting in a full tank.

How Can You Tell If Toilet Paper is Septic Safe?

Toilet paper brands are usually labeled as septic-safe to make it easy for buyers. But there are other things to look for like “biodegradable”, “recycled”, or “chemical-free” labels on packaging that indicate the paper would perform well in a septic tank.

An easy trick for telling if toilet paper contains chemicals is the color. Recycled and biodegradable options are usually a soft beige or off-white color. Papers with many chemicals in them are the ones that are pure white.

To test the dissolvability of tissue, take a square or two of the paper and mix it in a large cup of water. If it has dissolved into smaller pieces, it is likely fine for a septic tank. But if the sheet is still intact, it is probably too strong for your septic tank to break down.

Top Brands in the Septic-Safe Toilet Paper Space

Many brands produce toilet paper they deem septic-safe, but that doesn’t mean all these brands create equally septic-safe toilet paper. Some brands stand apart as being particularly great for those with septic systems.


Founded in 1879, Scott Paper Company has, at times, been the largest manufacturer of toilet paper in the world. They are no longer top-dog, but they still provide millions of homes with their bathroom tissue.

Scott has been a trusted brand for decades and works to evolve its brand to fit consumer priorities and reduce waste to contribute to sustainable business practices. They own brands such as Cottonelle, helping them dominate more of the market.


The brand began in 1928 with the mission to offer the softest toilet paper at a great value. Their goal has always been the comfort of their customers and regularly releases super, extra plush tissues for maximum comfort.

Despite their focus on comfort and softness, they make septic-safe, clog-safe toilet paper recommended by plumbers. Their patented diamond-quilt pattern increases comfort and absorbency, making it a staple of all their products.

Seventh Generation

Seventh Generation is the top choice for those looking for toilet paper made from recycled materials. Seventh Generation delivers septic-safe, eco-friendly toilet paper that is still comfortable and effective in the bathroom.

Seventh Generation began through Renew America, a non-profit focused on pushing energy- and water-conserving products to help reduce waste and be kind to the planet. Eventually, Seventh Generation branched off into their own business, but they began with the fight to help Earth and work towards a healthier, more sustainable world.

They also donate 1% of all sales to finding solutions for serious environmental issues. This exemplifies their commitment to helping the Earth that other companies don’t show.
