Wall mount sink

I'm putting in a wall mount sink and was going to cut the wall out to install blocking. I thought it was 1/4" wainscoting on top of 1/2" drywall but it turns out to be 1/2" plywood instead. The sink weighs 28lbs. Could 1/4" toggles work with this?? thanks

good news that it's plywood. 1/4" diameter steel toggle bolts is a great way to go. I wouldn't need 5/16" to feel secure, and I have been known to do calisthenics and gymnastics at home and elsewhere on anything that a few fingers can grip onto. What is the height distance between where the bolts are and the bottom edge of the back part of the sink touching the wall? This distance is the most important one in determining how much pressure will push into the wall when someone lifts themselves off the floor by pushing down on the sink. The risk is not that a toggle will snap or pull out, but that the sink will squish its way into your wall gradually at the bottom back edge.

We just bought a new corner wall mount sink for our bathroom, and when we got it out of the box, we had a couple of surprises. First, there was no hanging hardware included, and second, the sink just has a couple of D rings on the back for hanging. They're not adjustable, so we don't have a lot of choice as to where to put the nails/screws/whatnot.

The sink is about 30 pounds, and I'm fairly sure that we won't be lucky enough for the hooks on the sink to magically line up with the studs in the wall, so I'm going to have to hang it from screws in the drywall. The good news is that there's a sheet of drywall installed over another inch-thick layer of sheet rock, so there's a lot of material there.

So, first, can this be done safely? And if so, what is the proper hardware? I have a vague memory of the existence of widgets specifically designed for this purpose. Yes? No?

Even better if you can get a lag screw into a stud through one of the mounting holes.

www.wingits.com have some anchors that might work for you, but the best thing would be to probably cut some drywall out, install blocking, and anchor into that.

A hung sink can be subjected to a lot of pressure from people leaning on it, hanging on it , and banging into it. I would not hang one from anything but solid framing.

Some of the Wingits fasteners are ADA rated for safety bars at in excess of 300# each, but those are designed for use on a tiled wall. SOme of their other ones are rated at 100# in drywall. I think that their design spreads the load better than a typical toggle bolt, but still, a lag bolt or hanger bolt into a stud or solid blocking is probably better and cheaper.

Most drywall anchors are rated for a "vertical shear" load, NOT a cantilevered one which creates a pulling force on it.

WingIts has a toll-free tech support line. This is one anchor, rated to hold 300#

Up to this.. I learn something new.
