ᐅ Replace sink with a wall-mounted installation system

Hello everyone,

I hope you can help me: In my apartment, the previous tenants removed the washbasin that was mounted on a drywall support frame. At the wash area, I currently have a drywall partition with two holes spaced 28 cm (11 inches) apart, in which I see something that looks like nuts marked M10. Behind these nuts, there appear to be M10 threads/anchors or something similar. I was able to firmly screw an M10 threaded rod into the right hole for the new washbasin, but on the left side it is loose, even though I can’t screw it in any further. It also doesn’t go in as deep as on the right side. What could this indicate? And is it possible to fix this without having to remove the drywall and tiles?

I am a complete beginner when it comes to this kind of thing and I’m quite concerned after discovering this... I will have a plumber come, but I would like to be informed in advance about the options and possible costs. I hope you can give me some advice!

Best regards

Now it’s time to install the sink. The swivel nut was reinserted, and a standard nut with a washer was screwed on. I hope this will hold without a locknut on the back side of the pre-wall installation, but since the plumber installs it this way, I’m willing to trust that... especially since it’s not clear to me whether the manufacturer Walraven even recommends using a locknut on the back of the pre-wall installation.

That aligns with the very pragmatic solution from the installer. Once you know how it can be done, it’s always quite simple—in this case, just a simple nut from the front. Very neat 🙂
