I’ve got a heavy bathroom cabinet with mirror to an internal plasterboard wall. I was thinking of using plastic plasterboard plugs, for the two screws that hold the whole cabinet.
is this going to be strong enough?

    No….It has to be anchored to a wall stud

    No. If the cabinet is already heavy by itself, once you place stuff inside, it’ll be even heavier. Two screws with plugs won’t do the job right.

    I highly suggest you find the wall stud and anchor the cabinet to that.

    If there is no wall stud, then you’ll need to have better anchors. The ones that work the best are Triple Grip anchors and they work in drywall very well. I have some that hold up to 204 lbs.

    They are the BEST, bar none, anchors you can use!

    We sell a lot of heavy wall mount cabinets for the bathroom. Safety must come first.
    It is always recommended and many times required that you use heavy duty anchor screws that are driven right into the wood wall studs. You also dont want your paster wall coming down. You want the weight supported by the studs which are holding up the house, and not by the plaster. Depending on the size of the cabinet and considering studs are 15 1/2 inches apart on center, you need to figure out how many studs you have behind the cabinet. You should have one stud for every 12 inches of cabinet basically. A 24 inch cabinet should have at least 2 studs behind it. Centering it based on the studs will factor into it. You need to at least get one or 2 studs behind it. Inside the cabinet you will want to screw it in on the top and bottom to bear the load. If I were installing a 24 inch cabinet I would want 2 screws on top into the 2 studs and 2 screws on the bottom. You can use a stud finder to locate wall studs.

    You can buy screws and anchor bolts at your local hardware store. They cost so little it is not even worth buying on line. For instance when we are installing kitchen cabinets we can do an entire kitchen with one box of 2 1/2 inch wood screws costing $6.
