A few simple questions relating to a shower waste and a sink

[darrenh]

Hi all

A few questions if I may - thanks in advance.

1) Do you use 40mm pipe for the waste on a shower (same as for sink waste) - there shower is high pressure and gives off a lot fo water so i need it to be efficient!
2) I have a SCS hammer drill - what should I be using to drill a hole through 2 layers of brick for the 40mm pipe? Is there a special large drill bit for the job??
3) Sink - how do i hang a sink (without pedestal) to a plasterboard cavity wall (ie sink plugs won't be enough in plasterbaord

cheers

Cut out some plasterboard and fix a batten between studs to hang it on.
