Through The Twilight Zone, from a small contractor bathroom to another universe. The simplest materials, 4" x 4" black tiles with white grout, steel ball bearings, and the hands of a craftsman; transform the bathroom beyond wildest expectations. With two mirrored walls, facing each other, giving the illusion of "infinity"; and a mirrored ceiling doubling the visual space, it felt enormous. My client hosts her cocktail parties in here.
