We have black leathered granite on our curb. All bathroom hardware is polished nickel but I am considering using a black u-channel for the 3 sided frameless glass shower. The rest of shower glass hardware I think i would prefer to be same color as the polished nickel. I am considering the black for the u-channel to have the channel be less obtrusive. Thoughts? If anyone has done this or has pictures that would be so awesome, Thank you.
