Japanese electric-free toilet: why it's the best (and cheapest) choice
11 July 2026 — L'équipe Mizu
When we think "Japanese toilet," we often imagine a high-tech seat packed with electronics, complete with a remote control and a three-figure price tag. However, the version that's gaining the most traction in French households is much simpler: the electricity-free Japanese toilet. No outlet, no breakdowns, no renovations—just the essentials, water washing, for a minimal budget. Here's why, for most people, it's the best starting point.
In brief
- An electricity-free Japanese toilet works using water pressure, without any electrical outlet.
- It costs much less than an electric model and can be installed in 15 minutes.
- Zero consumption, zero electronic breakdowns, works even during power outages.
- Warm water comfort is still possible via a connection to the hot water supply of the dwelling.
- Ideal for discovering water washing without commitment or renovations.
How does an electricity-free Japanese toilet work?
The principle is disarmingly simple: the device connects directly to your toilet's water inlet and uses the main water pressure—the same pressure that fills your tank—to propel a jet of water through a retractable nozzle. No electronics, no motor, no cables. You open the dial, the jet starts; you close it, it stops.
Two forms exist: the attachable bidet, a thin plate that slides under your current toilet seat, and the mechanical bidet toilet seat, which replaces your existing seat. In both cases, the nozzle can be adjusted and rinsed, and the entire setup is completely reversible. For an overview of all types of Japanese toilets, consult our complete guide to Japanese toilets.
Electricity-free vs. Electric: The honest comparison
| Criterion | Electricity-free | Electric (washlet) |
|---|---|---|
| Price | Low (from ~70 €) | High (300 – 1,200 €) |
| Electrical outlet | None | Required (with ground) |
| Installation | 15 min, DIY | 20 – 30 min |
| Water jet | Yes, adjustable | Yes, adjustable |
| Hot water | Via hot water connection | Continuously heated |
| Drying / heated seat | No | Yes |
| Breakdown / power outage | Always works | Functions out of order |
| Consumption | None | ~20 – 30 €/year |
5 reasons to choose electricity-free
1. Price, first and foremost
This is the main selling point. While an electric toilet seat starts around €300 and quickly goes up, an electricity-free attachable bidet costs a fraction of the price. You get the main benefit—water washing—without the investment of a full washlet.
2. No outlet, no electrician
Most French toilets don't have a grounded electrical outlet nearby. An electric model would therefore require an electrician. The electricity-free version, however, completely avoids this constraint: it only needs the water that is already present.
3. Nothing to break down
No electronics, no circuit board, no motor: there's simply nothing that can burn out or go out of adjustment. A simple, robust hydraulic mechanism that lasts for years. And in the event of a power outage, it continues to function—unlike a washlet.
4. 15-minute, reversible installation
The connection is made to the toilet's shut-off valve via a supplied T-fitting. No drilling, no plumber, no permanent marks. You can remove it as quickly as you installed it. We detail everything in our installation guide.
5. Hot water is still possible
The only real compromise of the electricity-free version—a jet at mains temperature—is easily resolved: some models connect to the room's hot water supply (the one that feeds the sink), for a tempered jet, still without any power outlet.
The electricity-free, essential version
The Mizu Essentiel attaches under your toilet seat in 15 minutes and provides you with the essential—water washing—without an outlet, without breakdowns, without renovations.

The electricity-free Japanese toilet is ideal if you:
- want to discover water washing without a big investment;
- do not have a grounded outlet near your toilet;
- are a tenant and are looking for a solution without renovations or permanent marks;
- prefer simple and durable equipment, with no electronics to maintain;
- are furnishing a second home, a studio, or an auxiliary toilet.
Conversely, if you dream of warm air drying and a heated seat, the electric toilet seat remains the benchmark. Nothing prevents you from starting with the electricity-free version and upgrading later.
What about hygiene, in all this?
It's strictly identical. What cleans is water—not electronics. A clean, adjustable water jet cleans just as effectively whether it comes from a mechanical or electric model. Water washing remains, in both cases, much more hygienic than paper, which only wipes. We have detailed why in our investigation into the true impact of toilet paper.
Want a tempered jet, without electricity?
The Mizu Onzen connects to the room's hot water for a jet at the right temperature—still without any power outlet. The Mizu Zen, on the other hand, replaces your toilet seat with a complete mechanical bidet seat.

Frequently asked questions
Does an electricity-free Japanese toilet clean as well as an electric one?
Yes. Water cleans, not electronics. The jet is clean, adjustable in direction and pressure. The difference lies in comfort (continuously heated water, drying, heated seat), not in washing effectiveness.
Can you have hot water without electricity?
Yes, by connecting the device to the room's hot water supply (the one that feeds the sink). The jet is then tempered, without any electrical outlet or power consumption. This is the principle of the Mizu Onzen.
How do you dry yourself without a drying function?
A few sheets of paper are enough to dab after washing—you still reduce your paper consumption by 70 to 90%. The most committed use a small dedicated towel, for a completely zero-paper use.
Is it suitable for a tenant?
Perfectly. The installation requires no drilling or renovation and connects to the existing water supply. Disassembly takes 5 minutes and leaves no trace—ideal when you're not a homeowner.
