I’m never surprised by the incompetence or laziness people, even “pros”, do to unseen parts of construction. Many times they know it will work long enough to be someone else’s problem, which is quite unfortunate.
I see the same with tile. Installers skipping waterproofing is quite common. DIY folks trying to make it look pretty so they can sell the home for top dollar, etc. It often creates a much bigger problem for the next person to deal with.
That assumes the cabinets and studs line up. Previous place we were not so lucky when redecorating our kitchen.
We used quality anchors as well as placing an extra horizontal wooden "beam" below the cabinets for them to rest on, to minimize any vertical load on the anchors. The beam we could easily attach to the studs.
Held up for the years we lived there, even with lots of plates and such.
This seems insane to me. Any cabinet wider than 16" (or in extreme cases 24") is going to overlap with at least one stud. Why not screw into that stud? Any wood cabinet has a perfectly usable cross-piece for that purpose at both the top and bottom. If the cabinet is narrower than 16" I suppose you could chance it but I'd prefer to just move it sideways until it overlapped a stud.
The IKEA cabinets have a flimsy back, it's the sides that take the load. And moving sideways would have meant giving up a cabinet, not ideal in a small kitchen.
I see IKEA has improved their design now, with the cabinets hanging from a metal bar of sorts, which can be mounted to the studs. Guess there's a reason for that...
Oh wow. I'm surprised it's legal to sell a box like that under the name "cabinet". This is a product that has had a standard, functional form for centuries.
