Maria Nikolova_Ovcharov it looks to me that the tiles are glossy... And because there is a window behind the toilet seat, which gives even more natural light, it give the false impression of extra, glass-like, shine... See the rim on the left side of the shower? the groves go on straight under the shower rod, just on the same level with the corner tile. I bet it is just the tiles ... let see what others think, though... : )
Roloff Construction, Inc I think this is an actual shower rod through the glass end wall. The glass shop supplied the specialty rod and drilled the hole for the rod.
