According to Appendix 15, circuits start (and in the case of RFCs finish) at a DB.
As such the only way to comply with BS7671 when extending an existing circuit of a location containg a bath or shower, is to provide RCD protection for the circuit at the DB.
I would suggest that makes more sense than the Esc
