I am thinking about having a wall hung basin instead of my old pedestal. I have just put a a new mobobloc tap in this but will use that for my new basin. The basin I am thinking of buying has NO screws with it (or so it says)! and as I have never hung a basin before to the wall I wondered what length/thickness of screws and plugs I should choose? Any good types/brands out there I should buy to support the weight correctly?
