I have an opening in the bathroom which is slightly more than 27 inches. Height is not an issue, nor is the depth. I've looked at 25 inch and under stackables, and their capacities are just too small for our family. Is it safe to install a 27 inch stackable washer and dryer in this space? I've seen some places recommend 1 inch clearance on both sides, and a post here that seemed to indicate you could have zero inches of clearance. Going to a 27 inch size opens up a lot more options for me, including combos, and greater capacity. But before I make the purchase, I'm looking for some "expert" advice.
The side walls do have drywall on them, I believe 1/2 inch, and are on-load bearing 2x4 framing. I'm thinking also that if I needed to make the opening wider, I could remove the drywall and trim back the 2x4s a bit to compensate. Thoughts?
