Wonderful shelf

I have with me the shelf ordered to me in the bathroom just below the level a storage option to create! Looks wonderful and fits seamlessly into the "concept" a.
Want for the people who know if you can stick it: Yes it works without problems! What's needed is just the right glue. I was at the hardware store and I get some advice and they recommended me a silicone-type adhesive or adhesive polymer (Fix All - also suitable for wet areas), which now holds the bomb bay on the tiles! Just do the small aluminum bar so neat "coat", and eventually roughen short time.
