Hi @Showerbase,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.
The process is much the same as shown in How To Install a Shower Base.
There may be some particulars relating to your specific shower base that the manufacturer's instructions will address.
If you have any concerns with the process, it is best to speak with a plumber who will have the knowledge of installation practices to ensure you are in line with the Australian and New Zealand Standards.
Let me know if you have any further questions.
Jacob
