A nice medicine cabinet and, by extension, a handsome mirror can be the centerpiece of any bathroom and this modern sliding version is no different. It features all of the functionality of typical medicine cabinets but hides all of the ugliness behind the wall in a niche. An important part of this project is the wall’s stud size and location. Be sure to locate the studs before building the project and alter the dimensions to suit your needs. We designed the sliding mirror based on a 19-in. x 28-in. mirror and the 2x4 studs being 16-in. on center.

Rip and crosscut the 1/2-in. and 1/4-in. plywood to the dimensions based on the Cutting List. Cut the edge banding to a rough length with a utility knife. Iron on the edge banding to one edge of the cabinet shelves (A). Roll the edge banding with a J-roller or scrap wood to ensure good adhesion. Set the edge banding against the workbench and trim the excess edge banding with a utility knife. Sand the corners of the edge banding.

Glue and clamp the cabinet sides (B) to the cabinet rails (A). Drill pilot holes and fasten with 2-in. trim-head screws. Glue and clamp the 1/4 in. plywood cabinet backing (C) to the back of the cabinet. Fasten the cabinet backing in place with 2-in. brad nails. Glue the shelves in place, so that the edge banding faces out. Fasten with 1-1/2 in. trim head screws.

Cut a 1/8-in. deep x 1-in. wide rabbet into the edges of both mirror rails (F). Spread silicone adhesive into the rabbets of the mirror rail and attach the rails to the top and bottom of the mirror. Apply silicone adhesive to the 1/4-in. plywood mirror backing (H) and stick it to the back of the mirror and rails. Glue the ends of the rails and clamp the mirror stiles in place (G). Fasten the stiles in place with 2-in. brad nails. Fill the nail holes with wood filler. Sand the project and finish to your liking.

Place the cabinet into the niche, ensuring the cabinet is as far into the wall as possible and level. Attach the cabinet to the studs with four screws on each side of the cabinet.

Step 7

Attach the mirror to the wall

Place a 1-1/2 in. wide spacer board on the top edge of the facing rail (D) and scribe a line parallel to the cabinet. Repeat for the bottom of the cabinet. This is the centerline for the cabinet member. Measure the distance between the two lines on the wall and center the dimension on the back of the mirror for the drawer member.

Center the drawer member on the back of the mirror and fasten it with the included screws. Center the cabinet member on the wall and mark the screw locations. Screw in the hollow wall anchors at the marked locations. Place the cabinet member on the wall and fasten it with the included screws. With the cabinet members closed, slide the mirror onto the wall.
