Is RCD/RCBO protection now mandatory?

Not because its a shower as such[1], although fitting one for a
shower is very common. However if the cable run is "unprotected"
(i.e. cables not enclosed in an earthed metal screen, and its
buried in a wall at a depth of less than 50mm), then it would
need an RCD to comply with the requirements for cable protection.

I believe that is wrong now.

If you replace the cable with a larger one then the work you have
done has to comply with the current regulations which require an
rcd for every circuit in a room with a bath or shower.

It is regulation 701.411.3.3

Regs 510.2 and 134.1.1 apply and I have never seen a shower installation
manual that does not require the use of an RCD for the shower.
