How does a built-in sink dishwasher differ from a traditional dishwasher in terms of functionality and space-saving features?

A built-in sink dishwasher combines a sink and dishwasher in one unit, saving space and making it easier to wash dishes. Traditional dishwashers are separate appliances that require more space and Plumbing connections. Built-in sink dishwashers are more compact and efficient for smaller kitchens.
