Bidets & Bidettes

Are you proposing to install a Bidet or Bidette in your bathroom?
Depending on the sanitary fixture you choose, you may require a Plumbing Permit from council.


A bidet is a sanitary fixture equipped with a douche device for producing a jet of water, from a point below the rim of the pan, which can be applied to the body.

Bidets are not suitable for direct connection to the drinking water supply and require a Backflow Prevention Device. A testable Backflow Prevention Device is used to protect potable water supplies from contamination or pollution due to backflow. 

Under the Directors Specified List Category 4.2.4 Testable Backflow Prevention Devices are categorized as high-risk plumbing work and require a Plumbing Permit with council.

The following documentation is required for the submission of a Plumbing Application:

  • Form 3 Application for Plumbing Approval
  • Form 35 Certificate of Responsible Designer (Plumber)
  • Information pamphlet of Bidet
  • Photo of toilet (WC) that the Bidet is to be installed

If you have any queries regarding the above, please contact the Plumbing Department on 6217 9590 or email


A bidette is a sanitary fixture equipped with a douche, but over rim type water outlets, providing an airgap.

As bidettes do not require a Backflow Prevision Device, Councils Plumbing Approval is not required.

At completion of plumbing works, please provide a Form 80 Notification of Low-risk Works Notice to council.
