Toilet Paper Shelf - Just buy a "shadow box" from a craft store and paint! (I probably wouldn't use this idea specifically for a toilet paper shelf, but worth remembering for other places around the house)
modern home decor -- we would LOVE a wood sliding door. Sliding doors like these ones can really save space in rooms. These are some of the coolest sliding doors we've ever seen - they even added a coat hook!
I love the slanted wall, but the space of this giant bathroom seems kinda awkward. I love the natural light, and how clean it looks. I am kind of against windows in bathrooms. it just seems to impede with what a bathroom should be.
