Hello everyone,

I have a question about a sticking shower door and hope to get your opinion.

About a year after the shower was installed, the door (a fairly large glass door) has sagged to the point where it can no longer be opened or closed. We contacted the builder, but they attribute the issue to normal wear and tear.

In my view, the problem could be caused by a hole in the glass that is too large, or a shim or similar component might be missing that would better secure the screw and the door.

Could someone please take a look at the attached pictures and give me your assessment?
Also attached is the installation manual for the "shower door hinge," which I suspect was installed.

Thank you in advance!

Best regards

It is quite possible that the door has sagged slightly by using the holes provided. This can happen with large doors. Reducing the hole tolerance is generally not a solution because, on one hand, space is needed for fine adjustment, and on the other hand, the door must not rest directly on the screws to ensure that no stresses are introduced that could cause the door to crack. The glass is held in place only by clamping here. The recommended approach is first to check whether the hinges on the opposite side are still firmly installed and properly aligned ("in level"). Then reinstall the door and clamp it with the correct torque. If the instructions mention replaceable support pads for the glass within the clamp, I would also install new ones. Additionally, clean the glass thoroughly to ensure that no shampoo residue reduces friction.

Hello,

Thanks to your photo of the rear cover caps, I was able to shed some light on this through a search on bing.com (Microsoft’s search engine).

Perfect... the bushings are probably made of hard rubber, and the height can be adjusted using the eccentric cam. That should ensure it really holds securely.

Great, thanks to both of you @Peter_H_ & @ronfruehling.
I found a picture showing exactly how our shower looks.
Should the centering sleeves have been installed during assembly?
In other words, do we have a right to expect the builder to install them? Or should we just get these sleeves ourselves and install them? Thanks in advance.

It appears that the bushings are not necessarily included here, as only the rubber hoses are standard. If you feel confident, I would just quickly do it yourself rather than argue for a long time. However, depending on how much you trust your skills, it might make sense to involve the builder again.
