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.
A great way to really modernise subway tiles is to lay them in a herringbone pattern. Here the pattern is accentuated with black grout for greater contrast. We love how they have extended the tiles below the cabinet as well.
