Japanese Toilet Technology - results in the evolution of the Smart Toilet

If you are asking yourself what is a Japanese toilet? and why are they becoming so popular now?  Well, you are not alone.

Japanese toilets, also known as bidet or shower toilets, are toilets with integrated washlets.  They are either purchased as an add on electronic bidet toilet seat or complete suites that use a water cleansing, cleaning system that leaves you feeling clean, refreshed and rejuvenated. The Japanese bidet shower toilet reduces the need for toilet paper with its multi-functional cleansing experience. You’re able to tailor your use by using a control panel to adjust the temperature of the seat, water and warm air as well as the nozzle position. Some high end models includes an automatic deodorisation function to keep your bathroom smelling fresh. This bidet toilet attachment is a neat solution for effective hygiene, without wasting natural resources. 
Bidets have been around and are very popular in European bathrooms. Bidets were always a stand alone unit, a plumbing fixture completely separate to a toilet. A classic bidet is a miniature, bathtub-like unit with taps on one end. The user straddles themselves over it and a stream of water is used to perform a personal clean, similar function to toilet paper.

The most popular Japanese toilet in the Australian market is the TOTO brand. 

TOTO is the top leading manufacturer of luxury toilets and bidets throughout Japan and the world. They design their bathroom furnishings in accordance with their ethos of protecting the environment and its finite resources. TOTO was the first to invent the integrated electronic Washlet bidet in 1980. Since then, they have gone on to sell 33 million bidet seats throughout the world. The luxury Neorest model features a automatic night light, the toilet lid automatically opens and closes, auo flush and a Washlet cleansing option to rinse and freshen up after you have used the toilet. Other toilet models are the Basic+ washlet toilet suite as well as Toto toilet seats and washlet.

What is a Washlet?

Washlet is TOTO’s signature product. It is an electronic bidet shower seat that uses a water cleansing system that leaves you feeling clean, refreshed and rejuvenated.  Below is an image of  the TOTO Washlet Bidet Toilet Seat – TCF6412AT.

Evolution Of The Smart Toilets

Thanks to our love of world travel and technology, Japanese toilets and bidet toilets have recently surged in popularity. Bathroom product manufacturers have leaped on to this consumer interest and new technology has continued to rapidly advance. Big designer bathroom brands such as Villeory & Boch, Duravit, Gallaria and Argent have invested in this market to produce The Smart Toilet with the features and functions seen in Japanese  toilets and have released a combined toilet and bidet.

The modern smart toilet

With a modern smart toilet, the user does their business as per normal, then rather than using toilet paper or moving to a separate bidet to clean themselves, they use the toilets’ rear and/or front water nozzle features. Air nozzles then dry off the user. The water and air functions can be activated using buttons on a control panel attached to the toilet or via remote control, depending on the model.

Common features across different brands and models typically include:

  • Adjustable water temperature and pressure
  • Adjustable air drying temperature and pressure
  • Soft closing seats

Basic smart toilet models are characterised as hygienic, comfortable, convenient and gentle however if you’re looking for a touch of luxury there are also more advanced models on the market. Advanced smart toilets come with many additional features for optimal personal wellness, such as:

  • Heated seats with adjustable temperature controls
  • Adjustable water pulsating settings
  • Self cleaning nozzles
  • Rimless hygienic flush
  • Touch-less or automatic flushing using presence detection sensors
  • Ability to pre-set different user preferences via remote control
  • Bluetooth and MP3 capabilities
  • Automatic opening seat
  • Night light

Voice activation controls are also being developed and are well on their way to becoming available in the near future. Models with this type of technology would completely eliminate the need for the user to touch anything at all when going to the toilet for the most hygienic experience possible.

Benefits of installing a smart toilet in your home

  1. Hygiene – due to the wash-and-dry function, rimless technology and other automated and hands-free functions, smart toilets are deemed more hygienic than the average toilet.
  2. Sustainability – compared with traditional toilets, smart toilets use less water as no toilet paper is used, meaning less waste to flush (no double flush). Additionally, they help you reduce your carbon footprint as they drastically reduce the amount of toilet paper you need to buy.
  3. Comfort – smart toilets make the chore of going to the bathroom more enjoyable, no matter the temperature or time of day.
  4. Maintenance – without the risk of toilet paper becoming clogged, you can worry less about overall maintenance. Furthermore, if toilet paper is used, some models help avert an overflow by preventing you from flushing when there’s a clog.
  5. Cleaning – your cleaning routine is made easier in models that have self cleaning nozzles, rimless flushing and superior glazing.
