Used this as trim inside my shower with the marbled pencil trim. I used Carrara porcelain tile. Don't be afraid of mixing materials. This is carrara with ceramic subway tile. The pencil helps deal with the possible thickness differences.
Yesterday we showed you Team SRD gorgeous powder room, and today - I think we can all agree - her guest bathroom is equally as gorgeous! Safe to assume extra long showers are common in this crisp, clean space.
