I worked on a suite of height adjustable sinks for a large medical product distributor here in Australia. They use them to clean endoscopes in the back of the hospital. I thought I'd use the opportunity to build in a few extra details like a ledge for the staff to rest their arms on, space for storage underneath and a shroud that they can lean on when they get tired. It also protects the underneath from splashing, which means less cleaning.
We had to find and build in a leg system and plumbing setup that would raise and lower it by 200mm.
Ditto for the accompanying packing tables that they use to inspect and package surgical equipment for sterilisation.
