Are Bidets Better for the Environment? A UK Guide to Sustainable Bathroom Habits

- Producing toilet paper is far more resource-intensive than most people realise — trees, water, energy, and packaging all add up

- A basic sprayer kit costs under £30, fits any UK toilet in under 30 minutes, and requires no electricity or plumber
How Bidets Help the Environment by Reducing Toilet Paper Use
Every time you tear off a few sheets of toilet paper, you might not think about where it came from. But toilet paper production is surprisingly hard on the planet. It requires cutting down trees, using large amounts of water and energy for pulping and bleaching, and then shipping heavy rolls to shops. In the UK, millions of rolls end up in landfills every year, where they decompose and release methane — a potent greenhouse gas.
Bidets offer a simple alternative. By using a gentle stream of water instead of paper, a typical household can significantly reduce its toilet paper consumption. Over a year, that means hundreds of rolls saved. BBC News has reported on the environmental cost of toilet paper, highlighting that many popular brands come from virgin forests in Canada and Scandinavia.
The benefit goes beyond trees. Manufacturing toilet paper is energy-intensive and carries a meaningful carbon footprint per roll — from raw material to finished product. A bidet, by contrast, uses only a small amount of water per use and no paper. The water itself requires treatment, but the overall environmental footprint is considerably smaller.
To maximise the environmental benefit, keep a small stack of washable cloths next to the toilet for patting dry instead of paper. A few microfibre squares last for years and cost almost nothing to launder.
Water Use: Bidet vs. Toilet Paper – Surprising Facts
Many people assume that bidets waste water. In reality, the water needed to produce toilet paper is substantial. Industry estimates suggest it takes a significant volume of water to manufacture a single roll of standard toilet paper — from growing the trees to pulping, bleaching, and rolling. A typical bidet use, on the other hand, uses less than half a litre of water. Even with regular daily use, the water consumed by a bidet is far less than the water embedded in the paper it replaces.
The water saved by switching to a bidet becomes even more significant when you consider the UK's water scarcity issues. Regions like the South East are already under "water stress" according to the Environment Agency. Reducing demand for toilet paper means less water taken from rivers and aquifers for paper mills. UK government water conservation advice encourages households to rethink everyday products that carry a hidden water footprint — and toilet paper is a major one.
Of course, bidets themselves use water. But a well-designed handheld sprayer delivers a precise stream, so you use only what you need. Over the course of a year, the water used by a bidet is a fraction of what is used to produce the toilet paper you would otherwise buy. And unlike paper, the water goes directly into the sewer system for treatment, not into landfill.
Waste Reduction: What Happens to All Those Toilet Paper Rolls?
The UK produces more than 1.5 million tonnes of paper and cardboard waste every year, a significant portion of which comes from bathroom tissue. Most toilet paper is technically biodegradable, but in a modern landfill, the lack of oxygen means it breaks down very slowly, releasing methane as it does. The plastic packaging around multi-roll packs adds another layer of non-biodegradable waste.
Bidets eliminate almost all of this waste. With a bidet sprayer, you still might use a small piece of paper or a washable cloth to pat dry, but your toilet paper consumption drops substantially. That means fewer trees felled, less energy burned in manufacturing, and less waste trucked to landfill. Some UK households that switch to bidets report buying toilet paper only once or twice a year — usually for guests.
There is also the waste from sewage treatment to consider. Toilet paper does not fully dissolve in many older sewer systems, leading to blockages and fatbergs. Thames Water has spent millions clearing fatbergs that contained large amounts of undissolved paper. Bidets reduce the volume of paper entering the system, helping to keep drains clearer.
Why the UK Is Catching Up with Japan and Europe
In countries like Japan, South Korea, and Italy, bidets are standard. In Japan, the vast majority of homes have bidet toilets (called washlets). In parts of Europe, standalone bidets have been common for decades. The UK has historically been an outlier, partly due to post-war bathroom designs that prioritised low cost and simplicity. But that is changing.
British consumers are becoming more environmentally aware. Surveys suggest a growing proportion of UK adults would consider installing a bidet attachment to reduce their environmental impact. The rise of "zero waste" living and the shock of pandemic-era toilet paper shortages have also made people more open to alternatives.
Unlike electric "smart" bidets (which require plugs and complex plumbing), a simple handheld sprayer is cheap, easy to fit, and works with any UK toilet. It is a low-tech solution with a high environmental return. The Guardian has covered the growing interest in bidets during supply chain disruptions, noting that many UK buyers made the switch for environmental reasons and never looked back.
Addressing Common Myths About Bidets and Sustainability
Myth: Bidets are unhygienic. Actually, water cleans more thoroughly than dry paper. Handheld sprayers do not recirculate water — they use fresh water from your mains supply. The nozzle is self-rinsing, and you can wipe it with a disinfectant weekly.
Myth: Bidets are expensive to install. A basic handheld bidet sprayer kit costs from under £30. It connects to the toilet's water supply with a simple T-connector. No plumber needed. The savings on toilet paper will cover the cost within a few months.
Myth: Bidets use too much water. As explained above, the water used to make toilet paper far exceeds the water a bidet uses. A year's supply of toilet paper carries a water footprint thousands of times larger than the water a bidet sprayer uses in the same period.
Myth: Cold water is uncomfortable. Most people find cool water refreshing, not shocking. The spray is localised and brief. If you really need warm water, you can buy a dual-temperature sprayer that connects to the sink's hot water pipe — but it is rarely necessary.
Simple Steps to Make Your Bathroom More Eco-Friendly with a Bidet
Ready to reduce your environmental footprint? Here is how to start:
- Buy a handheld bidet sprayer kit from a UK supplier like EasySpray UK. Look for brass fittings (more durable than plastic) and a long hose (1.5m).
- Install it yourself in under 30 minutes. Turn off the toilet's water supply, unscrew the existing hose, attach the T-connector, and connect the sprayer hose. No special tools required.
- Adjust your habits. After using the toilet, pick up the sprayer and rinse for 3–5 seconds. Then use a small cloth or two squares of toilet paper to pat dry.
- Tell others. Share your experience with friends and family. The more people who switch, the bigger the collective environmental benefit.
You do not need to go fully paper-free overnight. Even reducing your toilet paper use by half makes a real difference. Over a year, every UK household that switches to a bidet contributes to meaningful reductions in paper waste, water consumption, and carbon emissions — small individually, but significant collectively.
The Bigger Picture: Bidets and the UK's Net Zero Goal
The UK has legally committed to reaching net zero carbon emissions by 2050. Achieving that will require changes in every sector, including households. Most people think about insulation, electric cars, or solar panels. But everyday products like toilet paper also count.
The paper industry accounts for a meaningful share of global carbon emissions. By switching to a bidet, you are reducing demand for paper manufacturing and shipping. It is a small action, but multiplied across millions of UK homes, it adds up. Government bodies like the Environment Agency and DEFRA encourage water efficiency and waste reduction — and as public awareness grows, bidets are increasingly recognised as a simple, low-cost tool for sustainable living.
Make the Switch for a Cleaner Planet – and a Cleaner You
Using a bidet is not just about personal hygiene — it is a vote for a more sustainable world. Less paper waste, fewer trees cut down, lower carbon emissions, and less plastic packaging. All from a small device that attaches to your existing toilet.
