Love the pull out shelf idea -- been trying to figure out how to get a folding surface in my tiny laundry. Replace with single dual function unit and use the upper portion for laundry, Pull out sewing machine storage under table.
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.
The one great thing about a laundry room is you do not need that much space. Convert a closet into your dream laundry room. A stackable arrangement conserves space but you can also install side by side washer & dryer with a counter top and cabinets above.
