My husband and I are planning to renovate our only full bath. We are expanding our current three piece bathroom to include a double vanity, a tub/shower combination, and a separate toilet room with a shower. We went to the tile store this weekend to pick out tile. We always knew we would do glossy white ceramic subway tile for the walls. We liked the idea of a gray grout. When we went to the store, I fell in love with a carrara marble basket weave floor tile with a subtle green accent stone (image attached). After this decision, the darker gray grout didn't seem to make sense anymore for the subway tile. Do you all think we need to do a white grout for the subway tile so that is looks good with the marble floor tile? All the images I can find of this combination have white grout. I'm not a huge fan of white grout due to its tendency to look dingy...always. Any opinions welcome!
