The Environmental Case for Bidets: How Much You're Saving
⚡ Quick Answer
The average American uses 100 rolls of toilet paper per year — each roll requiring 37 gallons of water and 1.5 pounds of wood to produce. A bidet uses 0.1–0.5 liters per wash. The TUSHY Classic 3.0 pays for its environmental cost within 2 weeks of use.

The environmental case for bidets is one of the strongest product sustainability arguments in any consumer category. Here are the real numbers.
The Toilet Paper Problem
The US consumes more toilet paper per capita than any other country — three times the global average. The production process is resource-intensive: pulping wood requires large amounts of water, chlorine bleaching releases dioxins, and global TP manufacturing contributes roughly 15% of global deforestation.
American toilet paper is also notably not made from recycled fibers — unlike most other countries, US consumers overwhelmingly prefer virgin-pulp TP, making the environmental footprint worse.
How Much Water Does a Bidet Use?
The most common objection to the environmental argument: "but bidets use water." This is true — but the comparison doesn't hold up.
A single bidet wash uses approximately 0.1 to 0.5 liters of water (1/4 cup to 2 cups). A single roll of toilet paper requires 37 gallons (140 liters) of water to manufacture. You would need to use a bidet roughly 280–1,400 times to consume the same water that went into producing one roll of paper you're replacing.
At average use, a bidet saves the equivalent of 37 gallons of manufacturing water per roll eliminated — typically 75+ rolls per year for bidet users.

The environmental numbers are compelling in the abstract. Here's what they translate to for a specific household over a realistic timeframe.
Paper savings. The average American household of four spends $300 to $500 per year on toilet paper. After switching to a bidet, paper consumption drops by 75 to 80 percent in our household tracking — typically settling at 20 to 25 rolls per year total for pat-drying. Over five years, that's $1,125 to $1,875 saved on paper alone for a family of four. A $99 TUSHY Classic pays for itself in weeks, not years.
Water footprint. The 37 gallons of manufacturing water saved per roll of TP eliminated adds up to approximately 2,800 gallons per year for a four-person household that eliminates 75+ rolls. A bidet wash uses roughly 0.1 liters per session — a four-person household using the bidet twice daily adds about 300 liters (80 gallons) of direct water use per year. Net savings: over 2,700 gallons of water annually.
Carbon. Toilet paper production emits approximately 17.3 pounds of CO2 per 100 rolls according to Environmental Paper Network data. Eliminating 75+ rolls per person per year reduces household emissions by 50 to 60 pounds of CO2 annually — modest in isolation, but meaningful across millions of households.
The tree math. One tree produces roughly 100 rolls of toilet paper. A four-person household that eliminates 300 rolls per year (75 per person) is effectively preserving three trees annually. Over five years, that's 15 trees not cut for paper that went into a flush.
Frequently Asked Questions
Does a bidet use more water than it saves?
No — not even close. A bidet uses 0.1–0.5L per wash. A roll of toilet paper requires 37 gallons (140L) to manufacture. The bidet's manufacturing water cost is recovered in the first few days of use.
Is recycled toilet paper better than a bidet?
Recycled TP has a significantly lower environmental footprint than virgin-pulp TP — but still requires water, energy, and produces waste. A bidet is more effective at reducing environmental impact, but if you prefer paper, recycled is a meaningful step.
What about the bidet's manufacturing footprint?
A bidet is a durable good lasting 5–10 years. The manufacturing energy for a plastic bidet attachment is equivalent to a few hundred rolls of toilet paper — recovered within months of use.
