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.
Tuck a retractable clothesline in to your laundry room cabinets to maximize your line drying space. Via Just About Home I already have the retractable clotheslines, but couldn't figure out where to put them.
