Since Covid and the infamous toilet paper shortages, we are getting asked about the installation of bidet seats and douche hand sprayers. Many of these enquiries eventuate from sponsored posts on Facebook promoting the DIY installation of bidet seats. The photo above perfectly illustrates a DIY bidet seat installation we recently came across in a client’s home.

We commonly come across these DIY bidet installations in clients’ homes. We are then placed in the invidious position of informing them that this is an illegal installation that requires disconnecting as it has no WaterMark approval and is not a compliant installation, as required by the Plumbing and Drainage Act 2018. Unfortunately, we are only the messenger, but immediately, too many people believe we are wrong. This occurs as the online company they purchased the bidet seat from told them they could install it themselves.

Imagine how we feel when we have to explain to a now disgruntled client that their DIY bidet installation is not legally compliant. Then explain that if it fails and floods their home causing tens of thousands of dollars of damage, their insurance company will null and void insurance protection.

Despite what Facebook posts say, very few legal DIY plumbing installations exist. Your insurance policy requires a licenced plumber to undertake all plumbing work with all plumbing fixtures installed with the necessary WaterMark approval.

Bidets, bidet seats and douche hand spray bidets are popular with the elderly and people with disabilities. Correctly installed, they afford their users self-care toileting which aids their independence, plus they are much more hygienic than toilet paper.

If you are looking into bidet seats or a douche hand spray, only purchase them from reputable Australian suppliers. Avoid online retailers with no prominent Australian location and not displaying a WaterMark approval.

No matter what, you must use a licensed plumber to install the bidet seat or douche hand spray to ensure there is no risk of backflow. A backflow situation can risk your family and neighbours consuming sewerage-contaminated drinking water. A legally compliant installation by a licensed plumber required lodgement of Form 9 with the local council and lodgement and payment of fees for a Form 4 with the Queensland Government QBCC. You should always get a copy of both forms to prove to your insurer that it is a compliant installation.

Remember, if you install a bidet seat or a douche hand spray, you need to do the following:

  • Purchase a WaterMark-approved product
  • Only use a licensed plumber to install your bidet products
  • All installations require high hazard backflow prevention

A bidet seat should not be confused with a bidet. A proper bidet must go through an entire approval process by council plumbing inspectors.

Like everything in life, you only get what you pay for, so we recommend you stay away from online retailers, especially on Facebook. The adage applies when finding cheap DIY bidet seats or douche hand spray hoses. If something sounds too good to be true, it probably is.
