Regularly airing out the bathroom with a bit of fresh air works wonders, too.

Smarter toilets to go even further

If this idea appeals to you, know that there are now clever systems designed to use even less water:

Dual-flush toilets: allow you to choose between a small or large flush depending on what’s needed.

Eco-friendly models: some modern toilets use as little as 2–3 liters per small flush.

Composting toilets: perfect for houses with gardens or in rural areas, these water-free systems are ecological and odor-free when properly maintained.

Every little step makes a difference, and these changes can even lower your water bill by several dozen euros a year.

Answers to common questions

Is it really hygienic?
Yes. Urine is naturally clean. As long as you clean your toilet regularly, there’s nothing to worry about.

And what about bad smells?
With essential oils and regular cleaning, you won’t have odor problems.

How do I convince the whole family?
Suggest trying it for just one week. Highlight the water savings, the benefit for the planet… and be patient—habits take time to change.

Can this work outside the home?
It’s best to keep this practice within the family. In public places, follow the rules out of respect for others.
