Royal Mosa’s Romain series of unglazed floor tiles lends a decidedly European flair to this COOP 15 bath. Special manufacturing techniques make each tile unique, while conventional and unconventional sizes make them versatile. “The proportion of these tiles is very different from typical square options,” says Lewis, who favors the 4-inch-by-24-inch absolute black tile shown here.
