How do I remove the thermostatic valve on a bath store shower bar mixer - i

[SteveCarrington]

I can’t get to the nut as it is in the mixer bar - is there a tool to use?
Thanks

How about taking the circlip off, and what it's holding on?

Either need a slim walled box spanner/socket or can you remove the end of the bar valve? The chrome looks like there’s a shut line- is the end held on with a grub screw at the back/bottom or can it just be pulled off?
