Grohe towel bars are some of the best. The finish and surface quality is great.The use of the double sided tape is perfect for easy and precise mounting.What's great is that you can also take them apart to flip the logo orientation and in some rare case to the bar shorter if you need. It can be done with confidence that one can reassemble to perfection.They use a plastic piece for holding the bar to the wall. I'm not typically for overuse of plastic on bathroom fixture. But this is done to make the mounting much easier, without loosing the quality. Once mounted it's plenty secure and looks prefect.
