How can I install a washing machine in the kitchen?
A friend of mine recently purchased a portable washer that hooks up to the sink. Are you sure this won't work for you, instead? It would avoid having to tear out cabinets, etc. to put an appliance never designed to be put in a kitchen, where it shouldn't be. It might be somewhat in the way when in use, but avoids taking up cabinet space when not in use, as it can be wheeled out into another room when not needed.

She purchased the kit that made a small washer portable (wheels, drain line that goes into the sink, and the hoses that connect to the faucet.)

Also, these units are typically of very small capacity, which might be a consideration. Is there no other area where a compact washer/dryer unit for condos would fit?
