Bathrooms as a sanctuary has been the trend for the last many years but natural stone in the bath have become huge lately. Most of these sport a neutral look and are happy to let the natural elements do the talking.
Take this Canadian bath for example. All pics courtesy Houzz.
The tumbled Botticino Marble in a subway pattern on the walls and Kult White Stone tiles on the floor play the perfect foil for the dark vanity.
In this California home Natural Stone tile, a simple white Ceaserstone counter top, and fixtrues that blend in create a serene look.
