Recessed in the wall between studs. Easily installed! Simply put construction adhesive (not included) on the back side of the frame and push it into the opening in your drywall. Four fully adjustable glass shelves are included. Concealed hinges, knob, and door are left undrilled so you can mount it to open in either direction. Natural pine and solid maple can be painted or stained. Framing in the wall around the opening is not necessary.
