For decades, Japan has had a complicated reputation in the UK when it comes to toilets. Travellers come back from Tokyo with wide eyes and strong opinions - equal parts baffled and converted. The heated seat. The warm water spray. The dryer. The remote control with more buttons than a TV. It's a lot to take in when you're used to a cold ceramic seat and a roll of Andrex. And yet, something is shifting. Quietly but measurably, the UK is warming up to the idea, and the numbers are starting to reflect that.
If you've landed here because you're curious about what Japanese toilets actually are, Washloo's Japanese Toilet Guide covers the full picture: features, costs and a British perspective on what to expect. This piece looks at the broader question: why has it taken us this long, what's changing, and is 2026 finally the moment the UK gets on board?
What Took Us So Long?
Japan reached over 80% household penetration for smart toilets years ago. South Korea isn't far behind. Parts of Europe, particularly Germany and the Netherlands, have been quietly ahead of the UK for some time. Yet Britain, a country that prides itself on bathroom culture and a certain level of domestic comfort, has been slow to act.
There are a few honest reasons for this.
The bidet problem. In most of continental Europe, a bidet sits alongside the toilet as a standard bathroom fixture. British bathrooms were never designed with one, so there's no cultural baseline for washing rather than wiping. When something has no precedent in your experience, it's harder to understand why you'd want it.
The plumbing assumption. A reasonable number of people assume that installing a Japanese-style toilet involves major bathroom work (ripping out the existing toilet, running new pipes, calling in a plumber for a week). In reality, none of that is true for a bidet toilet seat. But the assumption persists, and assumptions have a way of quietly preventing purchases.
The price perception. Smart toilets exist at a wide range of price points, but the ones that tend to get media coverage are the five-figure luxury models. That skews public perception considerably. A high-quality bidet toilet seat (one with a heated seat, warm-water wash, warm-air dry and a full set of adjustable features) is considerably more accessible than most people assume.
The embarrassment factor. This one doesn't get acknowledged much, but it matters. Talking about what happens in the bathroom (and what you'd like to happen differently) is not something British culture handles particularly comfortably. Products that require a conversation about personal hygiene have a slightly harder path to adoption than products that don't.
None of these is an insurmountable obstacle. And increasingly, they're being surmounted.
What's Actually Changing
Smart toilet sales in the UK climbed 50% in 2024 - a figure that would have seemed implausible ten years ago. Europe now accounts for over a third of the global smart toilet market, driven by demand in the UK, Germany and France specifically. The trajectory is clear, even if the starting point was low.
Several things are driving this shift simultaneously.
Post-pandemic hygiene awareness. Covid-19 changed how seriously people think about cleanliness and personal hygiene, not in a panicked way, but in a lasting, considered way. Products that offer a more thorough, hands-free hygiene routine have had a receptive audience since 2020, unlike before.
The bathroom renovation boom. The years of staying home prompted a significant wave of home improvement, with bathrooms among the most commonly upgraded rooms. People who were already spending money on a new bathroom started asking what else they could be doing differently. For some of them, the answer was a smart toilet.
The ageing population. Britain has a rapidly growing older population, and a significant proportion of smart toilet purchases are driven by accessibility needs rather than luxury preferences. A warm-water wash and dry that requires no reaching, no wiping, and no physical effort, as a standard toilet demands, is genuinely life-changing for someone with arthritis, limited mobility or post-surgical restrictions. That's a large and growing group of people with a very practical reason to make the switch.
Travel. More Britons encounter Japanese toilets in hotels (in Japan, South Korea, across Asia, and increasingly in premium European hotels) and come home asking where they can get one. Direct experience is a powerful sales driver.
The conversation is becoming more normal. Smart toilets appear more frequently in home renovation content, interior design media, and social platforms than they did five years ago. Familiarity lowers the threshold for consideration, and the threshold has been coming down steadily.
The Environmental Argument Is Getting Harder to Ignore
The average British family of four spends around £274 per year on toilet paper. The water cost of using a smart toilet for the same family is roughly £17.84 per year. That's not a rounding error; it's a dramatic difference in the ongoing cost of a basic daily function.
The environmental dimension is even more striking. Producing toilet paper is an extraordinarily resource-intensive process. It requires trees, water, bleaching chemicals and significant energy - all for a product that is used once and flushed away. For a country that describes itself as environmentally conscious, the continued near-universal dependence on toilet paper is a genuine inconsistency.
A 2015 study found that 81% of British toilet paper buyers said they would consider switching to recycled tissue if the quality were comparable. If that many people were open to changing their toilet paper habits for environmental reasons, it's reasonable to ask why a switch that is both more hygienic and considerably more effective hasn't followed naturally. The honest answer is probably that nobody had made the case clearly enough, and that the product hadn't been accessible enough to make it a real option for most households.
Both of those things are changing.
What British Bathrooms Actually Need
One of the practical obstacles to the adoption of Japanese toilets in the UK has been compatibility. Japanese homes have bathroom configurations, plumbing setups, and toilet pan shapes that don't always translate directly to British bathrooms. The products that have worked best in the UK market are those designed specifically for it - not imports from Japanese domestic ranges, but products built around the dimensions, water pressure requirements, regulatory standards and toilet pan shapes found in British homes.
Washloo is the only British-based Japanese toilet brand, which means the range is designed from the outset for UK bathrooms. The seats are compatible with the V-shaped and D-shaped pans found in the vast majority of British toilets. The electrical components meet UK wiring regulations. The water inlet connections are designed for UK mains pressure. These might seem like details, but they're the details that determine whether a product works properly in your bathroom or becomes a frustrating compromise.
Where This Is Heading
The global smart toilet market is projected to more than double in value by the end of the decade. Europe's share of that market is growing. The UK, starting from a lower base than much of Europe, has more room to grow, which means the adoption rate here is likely to accelerate rather than slow.
The signals are already visible. Smart toilets are appearing in new-build bathroom specifications. Premium hotel chains are installing them as a standard feature. Interior designers are including them in renovation briefs with increasing regularity. The conversation in the UK is shifting from "what is a Japanese toilet?" to "which one should I get?", and that's a meaningful transition.
None of this means the cold ceramic seat is disappearing next Tuesday. Cultural habits change slowly, and the toilet is not an area in which most people feel an urgent need to experiment. But the direction of travel is clear, and for the growing number of people who have already made the switch, the more common question is why they waited so long.
Frequently Asked Questions
Are Japanese toilets suitable for UK plumbing? Washloo products are designed specifically for UK bathrooms and mains water pressure. The bidet seat models connect to the existing toilet's water supply via a T-piece connector - no new pipework is required.
Do I need to replace my whole toilet to get a Japanese toilet seat? No. A bidet toilet seat fits onto your existing toilet pan in place of the standard seat. If you want an all-in-one smart toilet that replaces the entire unit, that option exists too, but it isn't necessary to get the core wash-and-dry functionality.
Are Japanese toilets hygienic? Yes, and by most measures, more hygienic than toilet paper. The self-cleaning nozzle rinses before and after every use, and warm water washing is more thorough and gentler on skin than dry wiping. For people with skin sensitivity, haemorrhoids, or post-surgical needs, this is a significant practical benefit.
Is it normal to feel sceptical before trying one? Completely. Almost everyone who eventually converts to a Japanese toilet was sceptical beforehand. Direct experience tends to resolve the scepticism fairly quickly - the water temperature, the pressure and the general experience are considerably less alarming in practice than people imagine in advance.
