We finalized our upstairs shower tile selection this weekend and spent 6 hours together building a sleek shampoo shelf. It's another Tau Ceramica porcelain tile (I love them!) called Gael. It's wavy like water and comes in 13x35 straight from Italia. We sized our shelf to be the exact size of a tile (after durarock & thinset) as not to mess up our pattern at all. This, along with showerheads on both sides, will make for an excellent showering experience.
