Porous cork probably isn't the first thing you think of for the bath. This new mosaic flooring from Sustainable Flooring
—created with 100% post-industrial recycled wine cork slices—holds up in wet and high-traffic environments. Quarter-inch-thick cork pieces are assembled on paper backing for quick and easy adhesion to subfloor. Once the sheets have been set and grouted (sanded grout is best for wet installations), they're sealed with a water-based polyurethane finish that keeps out moisture but offers the resilience and underfoot cushion of uncoated cork. Each sheet measures 12 inches by 24 inches.
