Dishwashers are a must have for most people, but what if you don't have the space to install a dishwasher? Consider a portable dishwasher. It must be stored somewhere, but it is pretty easy to use and it works as well as a built-in model.
Portable dishwashers are mounted on wheels to allow them to be easily moved to the sink. The water line is connected to the faucet and the drain line is slipped into the sink. Just plug it in and it is ready to go. While this may not be quite as ideal as a built-in model, it is still a good alternative.
One thing to consider though, a built-in dishwasher doesn't have to go right next to the sink. A dishwasher can be plumbed in to just about anywhere. If you have space for a dishwasher, just not in the usual place, a built-in is still an option.
