anything is possible.
there are small stackables that work on 120 volts.
we have a unit splendid and its a combo. some say they take to long to wash and dry a load. not really. its about the same , but with a dryer and a washer, you can be washing another load while waiting on the dryer
we hang pants and shirts right out of the wash cycle and only dry undies, t shirts and towels
it comes down to your space, weight and what makes you happy.
we had 8 years of no machine and it sucked, so adding a machine was a big plus,
its only the two if us so larger set up was just not needed
