While porcelain may be the most common material, contemporary bathroom sinks are available in stainless steel, concrete, quartz, and stone composite, as well as unconventional materials like resin, bronze, glass, and wood. Shapes and styles vary as well, with large rectangular slab style sinks popular in public restrooms and square, circular, or farmhouse sinks found in homes. Installation options include above-counter, drop-in, wall-mounted, and freestanding pedestal sinks.
