I'm wondering how difficult it would be to add an extra washer and dryer to our home. We currently have one frontloading washer and one frontloading dryer in the upstairs laundry room. My idea would be to either make those stacking (can be done with this type of washer/dryer and add another one that is stacking next to it.) I wasn't sure if I would have to add extra plumbing & venting if we did this. My other idea would be to add another washer/dryer downstairs in either the master bath or in the hall closet. Has anyone attempted this? We have a large family and are having trouble keeping with the large amount of laundry that goes into it!
