Native Trails expanded their NativeStone Trough bathroom sink line to welcome a new member to the family: the 30-inch Trough 3019. Previously only available in 48-inch and 36-inch versions, this smaller size option allows the Trough sink to suit petite powder rooms and narrow single vanities. Artisan-made from a breakthrough combination of natural jute fiber and cement, the Trough 3019 is lighter, stronger and far more sustainable than standard concrete, the company says. The Trough sinks are available in four finishes: Ash, a light gray color with beautiful natural mottling; Slate, a rich, dark grey; Pearl, a luminescent cream color; and Earth, at warm, natural brown-gray. Native Trails.
