Looking for advice on remodeling a VERY small powder room (5' x 5'). Our home style is modern with an Asian feel to it. With such a small space to work with, I'm guessing I'm going to have to keep the colors somewhat light in order for the room not to feel even smaller. The floor is a light gray porcelain. We've purchased a Toto wall mount toilet to reduce the space the toilet will take up in the powder room. I'm looking for ideas for the following:

1.) Suggestions for materials to use on the wall? I was thinking of bringing some texture to one of the walls. We have a large wall right outside the powder room that will be clad with Island Stone v-tile. Was thinking of perhaps bringing the same cladding to one of the walls. However it might be a bit heavy in a small room. Looking for other suggestions.

2.) Suggestions for a modern, low profile vanity.

Appreciate any advice that others may have.
