Designed for contemporary bathrooms, the Titus Floating Vanity Support brackets support up to 100 pounds per arm, without visible hardware. The 11-gauge galvanized steel supports—which each have a single extending arm and seven predrilled fastener holes—measure 18 inches by 10 inches by 2 inches and are mounted on either side of the cabinet. Two supports are needed for an installation. We found the supports online for about $40 each (right and left sold separately).
