The Best Toilet Paper for Septic Tanks: What to Look For

Think all toilet paper is the same? Think again—especially if you have a septic system. The wrong kind can build up in your tank, clog pipes, and reduce the time between pumpings.

Here’s what to look for when choosing the best toilet paper for septic tanks, plus a few top-rated options you can trust.

What Makes Toilet Paper Septic-Safe?

Toilet paper designed for septic systems should meet three main criteria:

• Biodegradable: Breaks down quickly in water
• No additives or lotions: Chemicals can harm tank bacteria
• 2-ply or thinner: Thick, quilted paper takes longer to dissolve

Bonus points for toilet paper labeled “septic-safe,” “RV-safe,” or “marine-safe”—these are made to dissolve easily.

Quick Toilet Paper Dissolve Test (DIY)

1. Fill a mason jar ¾ with water
2. Drop in a few squares of toilet paper
3. Screw on the lid and shake for 10–15 seconds
4. If it breaks into tiny pieces, it’s good. If it clumps? Skip it.

“We switched to a cheaper brand that said ‘septic safe’ and tested it ourselves. It passed the jar test and saved us on pump-outs.” – Drew C., Washington

Top Septic-Safe Toilet Paper Brands

• Scott 1000: Classic single-ply, dissolves quickly, budget-friendly
• Seventh Generation: Recycled and septic-friendly, no added dyes or scents
• Caboo Bamboo Toilet Paper: Eco-conscious, biodegradable, strong and soft
• Angel Soft (Septic Safe): Labeled for septic use, great balance of comfort and breakdown
• Quilted Northern EcoComfort: Septic-safe but softer than basic single-ply

Always read the label—even trusted brands have variations that aren’t septic-safe.

What to Avoid

• Ultra-thick, plush paper
• Paper with lotion, fragrance, or dyes
• Non-flushable wipes (yes, even “flushable” ones)
• Multi-ply luxury brands not tested for septic systems

When in doubt, go with simpler, thinner, and clearly labeled options.

Toilet Paper and Septic Health: Small Habit, Big Impact

Using the wrong TP won’t destroy your septic system overnight—but over time, it adds up. Thick, slow-dissolving paper increases solids and leads to more frequent pumping or worse, drain field problems.

Choosing the right toilet paper is one of the easiest and cheapest things you can do to keep your septic system happy.
