lavabos

Lavabos, or washbasins, are plumbing fixtures used for washing hands and face. They consist of a bowl-like basin connected to a water supply and a drain system, and are typically installed in bathrooms or powder rooms, often set into a vanity or countertop. Lavabos are designed to accommodate standard faucet configurations and drain fittings, and many include an overflow to prevent spills.

Common configurations include wall-mounted lavabos, which attach directly to the wall; pedestal lavabos, supported by a pedestal; console and wall-hung versions; undermount lavabos, installed beneath a solid surface; and vessel lavabos, which sit atop the counter. Materials range from vitreous china or porcelain and ceramic to stainless steel and various composites; finishes are glazed and come in a range of colors.

Installation considerations include appropriate mounting height, basin size, and faucet arrangement (single-hole, centerset, or widespread). The drain connects to the building’s plumbing and requires a P-trap. Some lavabos include an overflow to prevent flooding if the faucet is left running. For kitchens, bathrooms, and powder rooms, lavabos are often paired with vanity units or cabinets to provide storage and support.

Maintenance involves regular cleaning with non-abrasive cleaners to avoid scratching, removing mineral buildup, inspecting seals for leaks, and periodically cleaning or servicing the trap.

Etymology: the term lavabo derives from Latin lavare, meaning to wash. In Spanish-speaking regions, lavabos are commonly referred to as lavabos or lavamanos, with regional variations in usage.
