The wheels need to be installed. The unit is heavier than a standard dishwasher. I would recommend help with the wheel installation. As for the hookup to the water, it takes only basic plumbing skills for that. You water facet will determine what you need. Had to purchase a few items to complete the hookup, but it works fine. The dishwasher cleans very well but it does not dry as completely as I would like. It is as quiet as any built-in dishwasher I have used.
