Love the Mother of Pearl tile on the wall with the light grey floor tiles, awesome feature wall and white everywhere else. The high-rise sink with space underneath gives anyone some small extra storage space.
Walk-in shower corner for a spot to place a shower seat. Adding a white seat to the gray-tiled base lets the bench show up against walls gray-tile walls. The white seat also ties the bench to the mosaic-tile niches and river-rock-tile floor.
