Houzz is the new way to design your home.
Cross tile design. In grand upstairs bath do vertical line between toilet and tub and horizontal line at tub rim height depending on where the toilet top hits. Consider that.
Glass tile on left wall of grand bath in green. Cross design on right. With glass and Carrera marble on right wall.
Simple Carrera marble install but pattern of tile at diagonal
Nice wall break. Must need ledges.
Molding at top
