Sink by. This delicate, artisan process of hand applied gold leaf is captured between the two layers of glass in Vitraform’s Standard or Freestanding Basins. The Cubiste finish is offered on our Cristal Antique glass and may be ordered in Rose (R) or White (W) gold. Subtle variations on each basin may be expected as part of this sensitive and intricate technique. Custom requests for other glass colors will be considered by special order.
