What if you cannot spare cabinet space to install a built-in dishwasher? That is not a problem with portable or convertible dishwashers. These dishwashers are freestanding with casters that allow you to store the dishwasher in one place and roll it to the sink when you need to use it. Most have a butcher-block laminate top so that you increase your workspace in the kitchen. Several companies offer portable dishwasher models if you need this flexibility.

GE has four convertible models of dishwashers called Nautilus. These can remain portable or they can be converted to an under-the-cabinet dishwasher. They have TouchTap controls and a package to reduce noise. If left as portable, the wood grain laminate top makes an attractive countertop addition to the kitchen for added workspace. All four Nautilus convertible dishwashers are in the $500 range.

Kenmore has only one portable dishwasher model. This model has a butcher-block laminate top to increase your workspace in the kitchen. It offers two wash levels in four cycles, including a pots and pans setting. It has a standard insulation package, so it will not be the quietest dishwasher. This Kenmore portable dishwasher comes in a sleek black design.

Frigidaire has two portable dishwashers. The 24-inch portable dishwasher is a standard size. Holding 12 place settings, this portable dishwasher has a 5-level wash system including a high-temperature wash/rinse cycle and a pots and pans cycle. It includes up to a 6-hour delay option and an UltraQuiet III sound reduction package. The 18-inch portable model can save space in smaller kitchens. Because it is smaller, this model can only hold an 8 place setting. It does include a sanitizing rinse cycle and a pots and pan setting. With five wash cycles, it has a 2-level wash system. It does have a basic sound reduction package, but no delay setting. Both of these models retail around $447.

Whirlpool also offers two portable dishwashers, both with EnergyStar ratings. The first model is a 24-inch white model that can hold a 12 place setting. With a PowerClean system, it has five wash levels and five wash cycles including settings for pots and pans, china, and sanitizing rinse. It can have custom panels. It also has a self-cleaning filter and a 2, 4, 6-hour delay setting. This portable dishwasher has the basic sound reduction package. The second portable Whirlpool dishwasher has 3 levels of wash and a sound blanket. It holds a 10 place setting and can wash pots and pans. It comes in black but can have a custom panel. This model is priced at $398 while the first retails for $498.

Maytag has two portable models that are both EnergyStar rated. These are Jet Clean II models that hold 14 place settings. They have more jet spray nozzles on 3 spray arms than any other dishwasher for better cleaning on four wash cycles. A fully electronic control pad complements the sound reduction package to make this portable dishwasher perfect for any kitchen. The upper rack is removable to allow for tall pots and pans. Both models retail for $48.

Portable dishwashers allow more choices in kitchens that may need to maximize cabinet space. With the same power to clean as built-in dishwashers, portables can offer some flexibility in tight spaces. If you move and have room in your new house, some portable models can be converted to a built-in model.
