We are building a new home in the Historic District of Savannah, GA, where the exterior must adhere to historic appropriateness codes. We are not being obsessive about being true to the period with our interior design, so we are staying more transitional than colonial. Here's my question: we are putting Carrera marble on countertops in both the guest bath and master bath, using 12 in porcelain tile on the floors and porcelain tiles in the tub and shower surrounds. Is it weird to use a small amount of natural stone in the deco in the the tub and shower? The first pic is the stone that would go on the shower floor and in the niches. (The walls will be matte desert grey porcelain subway tile) The second would go in the tub surround. (The walls will be arctic white glossy subway tiles.) Are these ideas good or bad? Cool or weird?
