Which Cavity Wall Fixings For A Mono Basin?

[RustyScot]

Morning all,
I've recently replaced a plasterboard wall with Aquapanel, Could some kind soul please advise which would be the best wall fixings to use. The basin I'm planing to fit has four large mounting holes so I thought fisher bolts would be my best option but my local plumbing merchant only stocks the solid wall bolts.

Many thanks for reading this far

If it's a heavy basin, cut a letterbox and fix wood to the studs

If it's lighter you could try using expanding fixings of some sort , while "glueing" the whole basin to the wall with silicone. Usually works.
