Portable Dishwashers
A portable dishwasher rolls on casters and connects to your kitchen faucet with a quick-connect adapter, then drains back into the sink, so it works in a rental or an older kitchen with no space or plumbing for a built-in model. Many have a wood or laminate top that doubles as extra counter space, and some can be converted to a permanent installation later. Check the width — full-size 24-inch or compact 18-inch — the faucet adapter your tap needs, and where the unit will be stored between loads. Compact countertop dishwashers, which sit beside the sink and hook up to the faucet the same way, are listed here too.
