Why Water-Saving Bidets Are an Eco-Friendly Bathroom Upgrade

Bidets vs Toilet Paper: Environmental Impact

Did you know that producing toilet paper consumes over 37 gallons of water per roll? According to the NRDC, “The U.S. uses more toilet paper per capita than any other country, contributing massively to deforestation across Canada’s boreal forests.” When we pit bidet vs toilet paper environmental impact, the bidet clearly wins. Not only does it eliminate most paper waste, but it also helps reduce the carbon emissions involved in manufacturing, shipping, and disposal.

How Much Water Does a Bidet Actually Use?

Here’s the surprising truth: a bidet only uses about 0.125 to 0.5 gallons of water per use. Contrast this with the water used indirectly to make toilet paper, and it’s a steep difference. Some low-flow bidets now use even less! If you’ve ever asked yourself, how much water does a bidet save?, the answer is significant—estimates suggest up to 54% less water use over time compared to toilet paper routines.

Other Environmental Benefits of Bidets

Bidets aren’t just about lower water usage. They reduce sewer clogs caused by excessive paper waste, support compostable hygiene habits, and prevent overburdening wastewater facilities. In the big picture of how bidets help the environment, they touch on everything from waste reduction to cleaner waterways.
