The master bath in this pied-à-terre takes decadent minimalism to a new level. It’s a simple rectangle organized around a 30-inch-high white Corian core that holds the sink, mirror, and jetted tub. Rising from this luminous centerpiece is a ceiling-height mirror dividing the sink area from an infinity tub behind it. Streamlined, efficient, and unobtrusively inventive, the crowning touch is a thin water column that falls from the ceiling, fills the tub, and overflows to a lit channel around it.

“Normally the tub filler is put on the wall; we just put it on the ceiling,” says architect Paul Mankins. “If you fill it in advance, there’s not much of a conflict between having the tub filled from above rather than the side.” Our judges applauded the bath’s elegant organization and polished good looks.
