I was nearing the end of my bathroom remodel. I have a Black tub, black toilet, and a black sink faucet, I was in search for the perfect black shower doors to go against the light gray slate tile around the tub. Enter the Alvin from Niveal. These doors added just the right pop against the tile. I absolutely love how these look. It gives an elegant and refined look to finish off my dream bathroom. They were super easy to install and the operation of the doors is smooth like butter. They are not klunky or jumping off a track like some shower doors.
