The powder room. The half bath. The W.C. The loo. Once considered a lowly service bath, this tiny necessary has evolved over the years into a grand water closet of decorating drama. The simple pedestal sink and squeaky medicine cabinet of old has been replaced by garden urns, stone troughs and ornate gilt mirrors. The modern powder room is a miniscule exercise in set design, evoking everything from scared baptismal fonts to the natty English yard man’s garden room. As designers, it’s the one room that begs us not to hold back; a diminutive space that cannot hold too much over-the-top design. There, in privacy of a locked door, we get to plumb the depths of our wildest dreams and let creativity flow.
