I love the counter on top of the washer and dryer and extends all the way to the door and incorporates the sink. Under cupboard lighting is a good idea and I need a new laundry door and this could be an option, it will let more light in.
I might put this built-in in my master bath without the counter top and with built-in storage cabinets above. In a laundry room hampers in a vanity for sorting dry cleaning and laundry. I'm liking that! Also love the big counter.
