Like this arrangement for washer dryer. Countertop above w&d Benjamin Moore Rock Gray Bathroom and Laundry Room : Home with Baxter did an incredible job renovating their half bath/laundry room. The top paint color is Benjamin Moore Rock Gray.
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.
