Shower cubicle door

While sitting in the end washroom of our Corrinium I noticed that the orientation of the shower cubicle screen did not look correct. On closer investigation it has basically fell off the wall and is just held in the upright position by the retaining strap, the securing screws have all pulled out.
We have never used the shower or pulled the door shut, so I can only assume movement while travelling has caused the failure. Luckily there appears to be no damage where the bottom of the door has hit and is resting on the shower floor tray.
Has anyone else experienced this, and is there a better fixing method other than what would appear to be inadequate fixing screws x4.

Warranty claim PGA IMHO.

Looked at ours to see the screen is secured by four screws that affix into the shower cubicle entry surround. Screws look about 25mm long gauge 8? Maybe an easy fix yourself or as inspiredron suggests a warranty claim if the distance to dealer is not too far? Where fixings have come loose, you can reinforce by inserting a wall plug for that extra hold. Disappointing for you on such a new van. Regards.
