Renee that is exactly where my plug was!! Behind the wall where the washer plugs in. Allen just took a hole saw and put a hole right beside the dressing table he made me and put a grommet in it. We just ran our plug through there and plugged into the extra outlet. You can't even hardly see it! That way I can plug in a make up mirror and my hair dryer!Hmmm...I may have to explore some. Could be I have an outlet hiding behind the wall!
I believe I have a plug in the closet that's for the washer/dryer.
