A small, 45cm-wide dishwasher is useful when you don't have a lot of space. It's also very suitable for a household of 1 or 2 people. A small dishwasher model (45cm) has the same height as a normal dishwasher, but it's not as wide. The useful thing about a 45cm-wide dishwasher is that it takes up less space. You could fit it in a studio or a small apartment. With a maximum of 10 place settings, you'll have less room for your dishes, though.
