Vanity cabinet hanging on drywall?

[gluecifer]

Turns out one wall in the bathroom probably only has tiles + single drywall when I tried to mount a vanity unit...
And it's framed with a 7 cm void behind right where the screws need to go, from the plank wall behind to the outside of the tiles = 7 cm.

So there's a 3" thick plank wall innermost.

Preferably, it would look best without legs at the front of the vanity, but now it might have to be that way anyway. Does anyone dare to guess if it will hold for a 60 cm vanity with a sink, and two drawers underneath with stuff in them if some form of drywall anchor is used?

(Why it's framed the way it is, I'll speculate on another time)

Would not hang it with drywall anchors, get long screws and secure it to the pklank wall behind instead.

Would not hang it with drywall anchors, get long screws and fasten to the wooden frame wall behind instead.

I've been considering that too, but are there plugs that long? I drilled with 8mm through tile and drywall hoping it would work with the included plugs.

If you just use long screws, how tight can you go without cracking the tile/drywall?

edit. Maybe a French wood screw 8x140 type? Do you think you can skip the front legs then? It's intended to NOT have legs, in other words.

Found an image of how it looks/looked before, it's framed with standing 45x45, distance uncertain now..

Anyone else considering hanging up the vanity with, for example, French wood screws on single drywall + tiles IF you can also use longer screws into the planks behind?

I don't want to risk the vanity falling to the floor..

drill slightly larger holes and attach a long French screw with a spacer so that you don't clamp too tightly on the newly tiled wall... make the spacer some millimeters shorter than the distance between the back of the vanity and the old plank wall

If you like, you can calculate exactly where your studs are from the picture and hit one of them? Sounds like the best idea. Otherwise, you'll need to get some kind of sleeve that is long enough to attach it in the rear wall and then screw the vanity into the sleeve where it goes through the drywall or something similar if you want to do it that way.

Otherwise, it's probably best to use brackets.

Have now managed to locate two studs in the wall, so the rail that needs to be screwed to the wall will at least be attached to two studs with one screw each.

Will take a longer one and drive straight through the stud and into the plank behind.
