Have you ever thought about having a smart toilet in your home?

Maybe not, but if you’ve heard about Japanese toilets and their many benefits you might’ve been tempted to purchase one.

How do they work?

A Japanese, or smart, toilet basically allows people to do a variety of functions remotely.

That might sound a little strange. You might be wondering why on earth you’d ever need remote features in your toilet.

Let’s discover if Japanese toilets are all hype that we can, err, flush away, or if they have something great to offer.

What Are The Features Of A Japanese Toilet?

Japanese Toilet Features

Japanese toilets are growing in popularity in the UK, but why?

Here are their top features.

Their Lids Are Controlled By Motion Sensors

A Japanese toilet lid usually opens automatically when you approach the toilet. This means you don’t have to bend down to open the lid, which can be especially beneficial if you have mobility problems.

They Encourage Better Hygiene

One of the most interesting things about Japanese toilets is that they have spray arms so that you can be thoroughly cleaned after using them. This is why it can be said that a Japanese toilet is a combination of a toilet and bidet.

They’re Better For The Planet

Since they help you maintain greater hygiene by enabling you to wash yourself with water, you don’t have to use as much toilet paper as you normally would with a regular toilet. This means that Japanese toilets are better for the planet.

They’re Easy To Maintain

Are you sick and tired of having to clean your toilet with strong chemicals or dealing with toilet bowl stains that never seem to come off?

A Japanese toilet will make your life easier because it’s much more convenient to maintain. This is because it’s manufactured with a non-stick coating that prevents stains from forming.

They Have Customisable Features

You can customise your Japanese toilet to fulfill many more functions.

These include adjustable water temperatures, a heated toilet seat, and even night lights! How you customise these features is by making use of in-built controls or remote controls – hook up an app on your smartphone and you’ll be able to control your toilet remotely!

They Deodorise Your Bathroom

Your trips to the bathroom can become so much easier if you have a Japanese toilet installed, thanks to its deodorising function. The toilet contains deodoriser extractors that release pleasant fragrances when you’ve finished using the toilet. This ensures that your bathroom is always hygienic.

They Flush Automatically

Instead of having to flush the toilet, which could be stressful if you have mobility issues, some Japanese toilets flush themselves. When you’ve stood up from the toilet seat or have walked away from it, the toilet will flush automatically.

What’s so great about this is that since you don’t have to touch a toilet handle or press a button in order to flush the toilet, you can prevent the spread of germs.

Japanese Toilet: What Are The Cons?

Japanese Toilet Cons

  • One of the biggest potential drawbacks of Japanese toilets is that their buttons have Japanese words on them. If you don’t understand Japanese this can prove problematic.
  • They take some getting used to. If you’re used to using a conventional toilet, learning how to use a Japanese toilet might take a bit of time. It will involve some trial and error, and might feel a bit uncomfortable at first until you get used to it.
  • Japanese toilets are expensive. If you want to install a Japanese toilet in your home, you can do so – but it will cost you. In the UK, you can purchase Japanese toilets from retail shops such as Washloo. Their range includes toilets in a variety of prices, from £500 to £2,500.
  • These toilets can be tricky to repair. Since they make use of technology, these toilets can be difficult to fix if they experience faults. It might not always be easy to find a repairman who’s skilled in repairing smart toilets.
  • Some smart toilets use electricity. They require being connected to your home’s wiring system. However, you can find others that make use of batteries. You’ll just have to ensure that you replace their batteries regularly.

How To Use A Japanese Toilet

A Japanese toilet is operated by buttons that help you to achieve many functions, and sometimes its functions are completely touch-free.

Here’s what you need to know about using it.

  • When you want to use a Japanese toilet, it will either lift its lid when you approach or require you to press the 音姫 Sometimes waving your hand in front of the toilet will also work to lift the lid. Some models will make a flushing sound automatically, as a way of concealing any bathroom noises and making you feel more comfortable, so don’t be surprised if this happens!
  • The toilet will have a control panel. This is sort of like a remote control to operate the toilet. The most important button to know about is the flushing button. When you push it up, it will give you more water to flush, while pushing it down will cause it to use less water. Sometimes the flushing button is actually two buttons located on the control panel: one that uses more water (大) and the other one that uses less ( 小 ).
  • There are buttons for washing yourself with water after you’ve used the toilet. There’s a bidet button that is mostly for female users (ビデ ) while there’s also a button for cleaning your bottom (おしり).
  • You can adjust the flow of water and angle of the flow to get the best clean. You’ll find that technologically advanced models of the Japanese toilet will have these options – 水勢 for adjusting the water pressure and 位置  for adjusting the angle of the water stream. You will need to use arrows to choose the option you want.
  • A Japanese toilet is all about attention to detail and greater user-friendliness, and one of the features which really reflects this is the 音, or sound button. What this does is produce a fake flushing sound so you don’t have to worry about people within the vicinity hearing you use the toilet.
  • You can deodorise the bathroom after using the toilet by pressing the パワー脱臭

History Of Japanese Toilets

History

Have you ever wondered how Japanese toilets came about?

Their history actually dates back to 1903. Japanese inventor Kazuchika Okura took a trip to the West where he was inspired by the white ceramic toilets he saw in Europe to make Japanese bathrooms more modern.

At this time, Japanese bathrooms still made use of squat toilets that weren’t connected to any sewage system.

About a decade later, Okura invented the first flush toilet and then in 1917 he established his Toyo Toki company, which was later renamed TOTO.

After 1970, TOTO became a household name in Japan, and it was set to produce innovative toilets as the years passed.

In 1980, TOTO released their Washlet model, which had a bidet designed into its electric toilet seat. It was possible to attach it to an existing toilet, which made it versatile.

After making improvements to the Washlet, it became popular as a luxury investment and was sold to golf courses while appealing to businessmen.

By the end of the decade, TOTO had sold 10 million washlets and they were becoming staples in many places, such as department stores and restaurants. These days, you can find the Washlet in all Japanese hotels.

In 2002, TOTO marketed their Tornado Flush model which released water from the sides of the bowl instead of from above it. This resulted in less water needing to be used with every flush.

One flush of the Tornado Flush would result in the use of 3.8 litres of water, which is a lot less than what you’ll experience with conventional toilets – they can use between five and seven gallons of water per flush!

The regular Washlet is currently sold for $2,500 (approximately £3,500), but in 2018 TOTO also released their Neorest NX model which costs $6,000 (approximately £8,400) and it’s the world’s most expensive toilet. It has features such as a curved seat that feels more comfortable to sit on.

Do You Need A Smart Toilet?

If you’re looking for a toilet that offers lots of features to make your toilet trips more comfortable, a smart toilet will definitely appeal to you.

But do you really need one in your home?

Here are some things to consider that make having a smart toilet advantageous.

  • You want to save space in the bathroom. If you have a small bathroom, having a smart toilet is beneficial because these toilets are smaller than conventional ones. They usually ensure that the control panel and cistern are positioned on the wall.
  • You want to feel more hygienic. If you want to reduce how many surfaces you touch, a touch-free smart toilet is useful because it prevents the spread of germs. It also keeps your toilet more hygienic.
  • You want to reduce how much time you spend cleaning. You have a lot of cleaning chores as it is, so it helps to be able to use a smart toilet that doesn’t require you to spend a lot of time cleaning it. Smart toilets usually clean themselves or prevent the build-up of dirt, so you won’t have to worry about using powerful or harsh cleaning agents.
  • You have mobility issues. If you battle to use the toilet, a smart toilet makes it much easier to do so and also enables you to stay cleaner with less effort. By not having to reach behind you to flush the toilet or reach for a bottle of room spray to deodorise the bathroom, this also makes your bathroom trips more convenient.
  • You want to reduce your water bill. If you want to use less water, a smart toilet can help you to achieve this because of how you can usually choose between different quantities of water so you only use exactly what you need.
