Woven wooden shades would add a really nice texture to your room. You're right, I have a pair of double hung windows behind my tub. I've just ordered cordless cellular shades that will be 2 on 1 headrail and have the top down/bottom up feature for privacy and a view of the trees outside. I literally have to climb in my tub to adjust the windows or shades so they probably won't be moved very often. I'm planning to accent with purple so I'm hoping to find fabric for a valance to tie it all together and bring a softer texture into the room. You must be so anxious to be in your new home. I've never built a house before but I'm sure it would be both exciting and overwhelming.

Post a picture of your space. I think we help you better with a visual for those of us who don't necessarily have tile but might have good ideas.

Typically subways aren't used for an accent. What size and color are your subways and what is your field tile? A framed glass herringbone layout on the back wall would be pretty. This is an interesting use of subways for an accent. I love this bath where glossy ceramic subways are used for the bottom portion and glass subways above the penny tile. The ceramic tile is slightly larger than the glass.

Well, unfortunately, my kitchen is in no condition for public display at the moment, ha! But here is a picture of almost exactly how they look. I will note that we have grout that matches the tiles better than the grout in this picture, and the grout lines are very thin. I don't have white cabinets, they're more a medium wood, with black counters (I would change my cabinets, if I could--but that's not happening right now!). We got all new floors a few years ago, and this limestone blended everything, while still looking nice with the cabinets we have. We got blond wood floors over most of the living areas, but the tile in the kitchen. One thing I have come to appreciate about the limestone, is that there are many different neutral colors within each tile, but the overall effect is pretty consistent. Some of the white-is specks/spots here and there are actually fossils--which in my mind makes it really interesting.
