The second-floor bath in this Brooklyn brownstone was a complete gut job. We covered 3 quarters of the walls in large-scale marble tile—but the glass enclosed shower features a pony wall of marble tile that continues onto the shower walls and ceiling. A vessel sink sits atop a white-granite vanity / countertop that's large enough to accommodate an adjacent sitting area. A huge freestanding soaking tub remains separate from the shower—we really made the most of this space without having to make major structural changes. Black hex tile with white grout covers the floor.
