Winsome Kitchen, Wood, Natural, 25.5 inches

What are the measurements of the top surface? I have a microwave that would just barely fit but I'm unsure if the towel bar is included in the width.

Is the drawer big and sturdy enough to hold silverware? My silverware container is 15 inches long, 10 inches wide, 3 inches tall...

Can the towel bar be installed on either side?

What is the interior heights..space.from bottom shelf to underside of top shelf .... and space from top shelf above?
