This Architectural Drawing is AutoCAD 2d drawings of Side section details of Bathroom vanity. Position the backer rod in the gap between the cabinet and the wall. Add caulk to fill in the gap, but also to cover the backer rod and secure it in place. You can choose caulk in the color of your wall/tiles, or simply use transparent caulk so the color doesn't clash with your bathroom design. For more details and informations download the drawing file.
