Rhoda The walls are wallpaper.
The baseboard is the same stone material as the floor.
This is a guest bathroom, so it is not subject to frequent moisture.
Bill Fry Construction - Wm. H. Fry Const. Co. Durability and practicality are definitely considerations when choosing remodeling materials. Other images of this guest bathroom show a stunning stone vessel sink. For daily use, I'd go with an undermount, which this homeowner has done on the master bathroom.
