Cut List
We built a medicine cabinet with a frame 20 inches wide, 5¾ inches deep, and 30¾ inches tall. (Note: Counting the crown molding, the finished cabinet measures 25½ inches wide, 8½ inches deep, and 32¾ inches tall.)

Frame
1x6 clear pine top and bottom pieces: two @ 18½ inches, ripped to 5 inches wide

½-inch pine plywood back panel: one @ 18½ inches by 28½ inches

1x6 clear pine side pieces: two @ 30 inches, ripped to 5 inches wide

1x8 clear pine base board: one @ 21½ inches, ripped to 5¾ inches wide

⅜-inch pine cove molding for shelf supports: four @ 4¼ inches long

1x6 clear pine shelves: two @ 18⅜ inches, ripped to 4¼ inches wide

1x2 clear pine crosspiece: one @ 20 inches

2 ¾-inch solid poplar crown molding Cut to fit.

1x4 clear pine rails: two @ 15 inches

1x3 clear pine stiles: two @ 28⅜ inches

⅜-inch pine cove molding to trim mirror. Cut to fit.

¼-inch high-density fiberboard (HDF) mirror backing: one @ 18½ inches by 26⅞ inches

Mirror: one @ 21⅛ inches by 14¾ inches by⅛ inch thick

Use a compound miter saw and a circular saw to size the pieces according to the downloadable cut list. Sandwich the top, bottom, and back of the cabinet frame between the sides, applying glue where they meet, and fasten them with 1½-inch brads. Position the cabinet's base board flush at the back, with a ¾-inch overhang on the front and sides. Glue it and nail it with 1¼-inch brads. Use ¾-inch brads to tack in the shelf supports at the height you like.

Install the crosspiece flush at the top
of the cabinet frame with 1½-inch brads. Measure and cut crown molding to fit, making 45-degree miters at the corners. Install the molding ¾ inch from the bottom of the crosspiece with glue and 1½-inch brads.

Dab the ends of the door rails with glue and clamp them between the stiles. Use a pocket-hole jig and 1¼-inch pocket screws to fasten the rails to the stiles.

Fill the holes with wood plugs. Position the masonite mirror backing with a ¾-inch gap around the perimeter, and tack it in place with ½-inch brads. Flip the door over, apply mirror adhesive to the back of the mirror, and lay it in place. Cut cove molding to fit the inside of the door frame, making 45-degree miters at the corners, and glue it in place. Fasten the hinges 3 inches from the top and bottom of the door and onto the cabinet frame. Install the door pull.

Use a combination countersink bit and 2-inch wood screws to fasten the cabinet to the wall, making sure to hit at least one stud in two places and using wall anchors at the remaining holes.
