It's really important that the bathroom is a space that you enjoy, since you end up spending so much time there as you begin and end your day. When I design a bathroom it's about creating simplicity. The unique thing about designing a bath is that you can cover the entire room, from floor to ceiling, in one material a hard surface of tile or stone. This creates a simple and uniform environment. I establish a specific color and finish palette with each individual client and go from there.
Color can change the entire mood of a room.
My own bathroom is a windowless room, so I decided to primarily use navy blue shiny tile because it felt masculine. The blue makes the small bathroom feel really strong. It is really about trying to keep things simple and classic. Start with an idea or theme, maybe a color or style and then take it from there. Maybe you love blue and white, or maybe you prefer all white just figure out what look you love and use this as a starting point.
