A:Answer Hello, thank you for your question. In the case of this dishwasher, the term "Spacesaver" refers to its smaller dimensions and ability to be installed underneath a sink. This undersink model has smaller capacity, but is the same height and width of a standard model. However, it has a half (front to back) upper rack so that it can make room for the sink bowl from the sink above it. We hope this helps! Please feel free to reach out with any further questions or concerns. -Chris@GEA
