Black gloss tiles

I'm interested in doing something similar to the attached photo for a bathroom reno, with black gloss tiles on the wall (which would include the shower). Just wondering if anyone has experience using similar tiles and how bad the problem is with water marked/soap scum. I've seen plenty of terrible photos of matt black floors, but can't find much about black gloss wall tiles. Thanks in advance
