It works much like a standard, fixed-mount shampoo bowl except for the important fact that it can be raised and lowered, using a hydraulic foot pump, a full 12 (or 14 with the E140) inches from a bowl height of 34 to 46 inches. This allows for an extremely comfortable fit to be established between the salon patron’s neck and the shampoo bowl. The comfortable fit eliminates back and neck strain and eliminates getting water on the patron and the floor. The Adjust-a-Sink can be used with a standard salon chair or a wheelchair. This allows the salon to be totally accessible as the patron can remain in their wheelchair during shampooing. This eliminates the possibility of accidents caused when someone is moved from a wheelchair to a salon chair.
