What is a "backwash unit"?

A backwash unit is a specialized chair and basin combination typically found in hair salons. It is designed to provide a comfortable and convenient space for washing and rinsing hair. The chair is equipped with a reclining backrest, armrests, and a built-in basin at the back. The basin is usually deep and contoured to support the client's neck while allowing water to flow away. A water source and adjustable faucets are connected to the unit for easy access to temperature-controlled water. The backwash unit is used during hair washing services, allowing hair professionals to thoroughly cleanse the hair and scalp while providing relaxation and comfort to the client.
