Typically, a kitchen dishwasher will fit a 24-inch space under the kitchen counter and has a hot water pipe, drain, and electrical wiring to hook up. While this is the most common, this is not the only size out there. There are designer drawer dishwashers that are typically more expensive, but they are also sleek, compact, and allow for separate washing cycles. The drawback is that consumers have found this individual style does not clean as effectively as the larger group wash. There are compact and even portable dishwashers as well, starting at $400 for those who have smaller living spaces. But when most people purchase a dishwasher, they are selecting the standard built-in model.
