Designing a Bath

I have a friend who is about to do a bathroom reno in her very cute cottage in a great area of town. The area although lust worthy is also know for homes that are more on the tiny side. Her style is quite modern and she loves a glamorous space. She wants a floating vanity and I fell head over heels for this one. She also wants a large subway tile with dark grout, but I also think a 6x12 marble tile would be quite stunning too. It would be chair rail height all the way around and cover the front side of the bathtub. A dark slate floor would ground the space. Along one wall they are going to incorporate built in and shallow shelving. I think making the shelves in a natural wood would offset the clean lines of the bathroom quite nicely. I always love incorporating raw elements into a room. Must be the natural hippie in me. Ha. The West Elm lighting would add the touch of sparkle and shine she loves. This friend also loves color,  but tires of things easily. I think fun fouta towels could do the trick and she can change out the colors to fit her mood. Too be honest I wouldn't mind having this in my own home and my style is neither modern or glamorous.
