I just bought a new washer and dryer for my new apartment. I would like to know if I will have any difficulties installing these two machines into the closet space next to the kitchen. My apartment is situated on the 11th floor, ofcourse I will hire a plumber to do the whole installation bit. The closet space will have to be constructed for the machines, will this be a difficult job? The plumber's rates are $43 an hour, how many hours does a job like this take?
