Maybe it's because our apartment unit lacks both the space/hookups for a washer, nor offers the appliances around the building, but we often daydream of having a kitchen large enough to even consider adding a washer unit in or around the kitchen. In Europe and Asia, kitchens with washers and dryers are common, but here in the US square footage is more abundant, so there's a separation of work spaces. Would you be averse to integrating cleaning functions into a single area? Or is the notion an attractive space saving idea?
Of course, you could have the best of both worlds, with a Smeg Small Space Washer With Sink
or just move the whole unit to your bathroom
