Attaching chrome bottle trap to 32mm concealed pipe

[capital1965]

I am building a new bathroom and the basin waste pipe will be concealed behind a tiled wall. I will have a chrome bottle trap joining it horizontally. Once the pipework is boxed in with a hole to join the trap to the waste pipe, how do I attach the trap pipe to the plastic waste pipe as I won't be able to access it with a tool or my hands to tighten it.

There is a Gerberit trap (151.024.21.) which appears to have a push fit collar but doesn't seem to be available in the UK.
