For most American households, the roll on the holder is as permanent as the sink. It has survived price spikes, shortages and the great panic-buying of 2020. But in more and more bathrooms around the world, it is quietly becoming optional. The change started in Japan decades ago, spread across Asia and Europe, and is now one of the strongest bathroom trends of 2026. It doesn’t involve a new kind of paper. It involves water.
The device behind it goes by several names, washlet, smart toilet or bidet seat, and it combines the functions of a toilet and a bidet in a single unit. Once reserved for luxury hotels and trips to Tokyo, it is now showing up in ordinary homes, and architects and designers increasingly treat it as standard in new bathroom projects.
What it actually does
Instead of relying on paper alone, cleaning is done with a jet of water. On most models, the temperature, pressure and direction of the water can be adjusted. Depending on the version, you’ll also find a heated seat, warm-air drying, a lid that opens by itself and sensors that detect when someone sits down. Many include antibacterial surfaces and self-cleaning programs for the nozzle.
The point that convinces most people is the simplest one: water cleans more thoroughly than paper, with less friction on the skin. That is why the washlet has been the norm in Japanese homes for years, and why people who try one while traveling often come home wanting one.
Why it’s taking off now
Three things have pushed the trend beyond Asia. The first is comfort: the smart-home movement has reached the bathroom, and a heated seat on a January morning is an easy sell. The second is hygiene: less direct contact and a cleaner result.
The third is environmental. Toilet paper is a daily, disposable product made from wood pulp, and a household that switches to water cleaning uses far less of it. Some manufacturers go as far as saying paper can largely be replaced. In practice most people keep a little for drying, but the roll lasts a great deal longer.
You don’t need a new toilet
This is the part that surprises people. A full smart toilet is a significant purchase, but the same idea exists in two much simpler forms:
- A bidet seat, which replaces the existing toilet seat and connects to the water supply valve behind the toilet. Heated and warm-water models need a nearby electrical outlet.
- A bidet attachment, a slim unit that fits under the seat you already have, with a small side dial. Most run on cold water only and need no electricity at all.
Both connect to the same valve that feeds the tank, and many homeowners install them in well under an hour with basic tools. Renters often choose the attachment because it comes off without a trace.
What to know before switching
Water cleaning doesn’t mean no cleaning. Even with self-cleaning nozzles, the seat and the bowl still need the same regular disinfection as any toilet, and the nozzle deserves a wipe now and then. If your bathroom has hard water, mineral buildup can affect the nozzle over time, and the same method that clears limescale from the bowl keeps it flowing.
Check the space around your toilet, too: some models need a few extra inches of clearance, and the heated versions need a grounded outlet within reach of the cord.
The roll isn’t disappearing tomorrow. But in a growing number of bathrooms, it has stopped doing most of the work. That’s the trick.
Tried a bidet, water shooting at my butthole is not my idea of a good time, add in the fact that sometimes you really need to dig in there to get everything gone.
