Smart Toilets, Japanese toilets – or just old-fashioned bidet seats – they’re a vital piece of NDIS and Aged Care kit. They’re also an in-demand upgrade to bathrooms across Brisbane.

Bidets were invented in France during the late 17th century, making them far from a new concept. However, they’ve come a long way from the bathtub-shaped basins that the aristocracy straddled to clean themselves after using the chamber pot. Modern bidets come with all the mod-cons we’ve come to expect from living in the digital age, including features like water temperature control, heated seats, self-cleaning nozzles, soft close lids, deodorisers and energy saving modes, to name but a few. Considering the environmental, hygiene and comfort benefits they provide, as well as the greater independence they provide people with disabilities, NDIS participants and those in aged care, it’s little wonder that bidets are growing in popularity in Australia.

With a wide range of bidet options available, from bidet seats that can be retrofitted to your existing toilet to fully integrated ‘smart’ or ‘Japanese’ toilets with all the latest features built in, there is an option to suit virtually every home, budget and lifestyle.

But, before you jump on the bidet bandwagon, there are a few practical consideration you need to be aware of.

How to Avoid Having a Non-Compliant or Incorrectly Installed Japanese Smart Toilet or Bidet Seat

As bidet popularity grows, plumbing professionals are seeing a growing number of installations that do not meet Australian standards. There are several reasons for this but the most common are:

  • Bidets sourced from overseas retailers are often not certified for Australian plumbing systems and may lack the required backflow protection.
  • DIY installations are not only a bad idea, but they’re also illegal. Bidet installation must comply with AS/NZS 3500 to ensure backflow prevention and safe water usage. Due to the risk of contamination water entering the potable water supply, all bidet seats, attachments and hand-sprays are classified as high hazard plumbing and must be installed by a licensed plumber.
  • Incorrect installation by an inexperienced plumber.

Queensland regulations require appropriate backflow prevention to protect the drinking water supply. Recent guidelines from the Queensland government highlights that some toilet douche seats require high-hazard backflow protection unless they incorporate a compliant Air Gap (AG) or Atmospheric breaker (AVB), and all products must be WaterMark certified.

This doesn’t make installation difficult — it simply means it’s worth checking suitability before buying.
