How do smart toilets help save toilet paper and water every day? When we think about saving water at home, we often imagine showers or faucets. Yet, conventional toilets account for a significant portion of household water consumption. Added to this is the daily use of toilet paper, the production of which requires substantial natural resources.

Smart toilets, also known as Japanese toilets, washlets, or bidet toilets, offer a modern alternative that improves hygiene while reducing toilet paper consumption.

What is a smart toilet?

A smart toilet is a toilet equipped with a water-washing system. After use, an adjustable water jet cleans the area, often followed by warm-air drying, depending on the model.

This type of equipment is available under several names: smart toilet, Japanese toilet, washlet, or bidet toilet.

These terms all refer to the same principle: replacing much of the use of toilet paper with a water wash, which is more comfortable and hygienic.

How much toilet paper do we use each year?

Toilet paper is an everyday product that we rarely pay attention to. Yet, our consumption is substantial.

On average, one person uses between 90 and 110 rolls of toilet paper per year.

For a family of four, this represents approximately:

360 to 440 rolls per year

several dozen kilograms of paper

several hundred euros spent each year, depending on the quality of the paper chosen

Beyond the cost, the production of toilet paper requires:

wood fibers or recycled paper

substantial water consumption

energy for processing and transport

chemical treatments for bleaching certain ranges

Toilets account for substantial water consumption

Each flush generally uses between 3 and 6 liters of water, depending on the toilet model.

One person uses the toilet about 4 to 5 times a day, which is:

between 12 and 30 liters of water daily

up to more than 10,000 liters of water per year

For a family of four, annual consumption can exceed 40,000 liters of water solely for flushing. This is one of the largest sources of water consumption in a home.

A bidet toilet significantly reduces paper consumption

Contrary to popular belief, water washing means using much less toilet paper.

After cleaning, some people use only a few sheets to check that the skin is dry, while models equipped with warm-air drying can further reduce the need for paper.

Depending on individual habits, a bidet toilet can reduce toilet paper consumption by 80 to 100%. For a family, this represents several hundred rolls saved each year.

How much can be saved?

Let's take the example of a family of four.

With conventional toilets

approximately 400 rolls of toilet paper per year

a budget between €250 and €450 per year, depending on the quality of the paper used

With a Japanese toilet

If paper consumption decreases by 90%, expenses can be reduced to just a few dozen euros per year. The savings can reach several hundred euros each year, while producing less waste. Over several years of use, this represents significant savings.

Better daily hygiene

The use of water provides a feeling of cleanliness that paper alone cannot always offer. This is why Japanese toilets have been used for many years in several countries.

The main benefits are:

better hygiene

superior comfort

fewer irritations caused by paper

a solution suited for elderly people, pregnant women, or people with reduced mobility

a significant reduction in toilet paper consumption

A gesture for the environment

Reducing toilet paper consumption also helps limit:

waste production

wood consumption

the water and energy requirements for paper production

Combined with responsible habits, a smart toilet is a modern solution that combines comfort, hygiene, and respect for the environment.
