Hello @greghale 

Welcome to the Bunnings Workshop community. Its sensational to have you join us, and thanks for sharing your question about your waste pipe.

If you are referring to the standard 32mm wastewater pipe under your sink, the outer diameter is 32mm. Are you in the process of repairing or replacing a damaged section of the pipe? If you can provide more details about your project, I'm sure our members will be able to offer advice and information.

If you have any other questions we can help with, please let us know.
