    I'm open to correction but i believe most shows with a max 8.5kw can be run on 6mm cable, obviously length of run would be a major factor.

    6sq will be fine once it's not an extensive run, 8.5kw shower will draw around 37amps so protect the cable with a 40amp RCBO.

    Don't have a cable sizing table to hand but on a 9kw unit I'd probably go 10sq under a 45amp RCBO to be safe.

    If it was a 9.5kw shower, you see a problem with a 45 amp RCBO on 10 square?
