Lad doing my bathroom today was about to hang the wall-hung sink on the wall (no plinth). Stud wall, that he previously opened up to embed pipework, before plasterboarding and tiling. Turns out he didn't put any studs/noggins in place to take the bolts on which the sink is to be hung. I stopped him from carrying on, and called his boss.
Boss insists it's not a problem, with the right plasterboard fasteners plus appropriate adhesive on the back, it will be more than strong enough. Sink weighs 16kg, presumably holds around 5-10L of water, plus gets leaned on of course.
I'm pretty old school with these things, and to me, drilling into a stud/noggin is the only way this should be done. But am I behind the times and getting my knickers in a twist over nothing? If needs be, we'll take the tiles off and do it again, but if it's really the case that plasterboard fixings are more than adequate (wall is tiled too, with 300x600x10 tiles), then I don't want to be that old **** who insists he's right and creates more work than is needed, even if I'd prefer it that way.
Thoughts?
