About this detail

A commercial lavatory vanity assembly featuring a one-and-one-quarter-inch stone backsplash with eased edges and a matching stone countertop. The vanity top is supported by a two-inch waterproof building panel and three-by-three-by-one-quarter-inch hollow structural section tube steel in-wall brackets spaced at two per vanity top, anchored with five-and-one-half-inch by nine-inch by three-eighths-inch steel plates secured by two expansion anchors embedded three inches minimum. An under-mounted lavatory sink is integrated per mechanical drawings, with pipe wrapping insulation specified for the assembly. The wall assembly consists of five-eighths-inch sheathing over framing finished with tile set in a solid thin-set mortar bed, incorporating a Schluter Dilex series movement joint profile matched to the tile thickness. Fluid-applied waterproofing is applied at the floor and extends up the wall one foot, complemented by a polished mirror above the backsplash.
