Are 18-inch dishwashers actually worth it for small kitchens?

Verified-purchase reviewers and r/HomeImprovement contributors agree 18-inch units are a real space saver, but with two caveats: capacity drops noticeably (typically 8 place settings vs 12), and the circular spray-arm pattern leaves the front corners of the rectangular tub less thoroughly covered. They're best for 1–2 person households or as a secondary unit.
