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 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.
