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.
Full height cabinetry allows for easy concealment of brooms/mops/vacuum cleaner. Having the washer and dryer separated creates more benchspace in an already tight area. Perhaps framing the dryer with cabinetry would create a more streamlined look.
