Toilet paper quietly costs the planet forests, water and carbon. Here's the honest math — and what changes if we switch.
Most soft toilet paper uses virgin wood pulp — including old, carbon-rich forest. A cut forest stops storing carbon and releases what it held.
Pulping, bleaching, drying and packaging are energy-heavy. Producing a single roll emits roughly 1.5 kg of CO₂ — for something used once.
One roll takes ~140 L of water to manufacture. A bidet uses about half a liter per use. The "water-saving" paper already used a bathtub.
People who switch cut paper use by up to 75%. Less forest, less carbon, less water — for a one-time ~$40 device.

Businesses buy toilet paper by the pallet — and flush the same math at scale. We built a separate calculator for that.

So why is most of the West still wiping? Not because anyone weighed it up and chose it. Because no one ever questioned it. It's the default we inherited — kept alive by habit, a little embarrassment, and an industry that quietly sells us a forest every year.
The strange thing was never the bidet. It's that we ever agreed to the alternative.
Everyone assumes a bidet wastes water. Making one roll takes about 140 liters. A bidet uses roughly half a liter per use. You're not adding water — you're using far less of it.
