Measure the corner of the bathroom where the cabinet will be placed to get the desired dimensions. The featured project's one side is 18" wide and the other is 18-1/2" wide (when attached together, each side will be 18-1/2" due to the plywood's thickness).
Since the piece is angled, the sides and cleats need to be mitered at the front so the front facing will lay flush. Set the circular saw at a 45-degree angle and cut the plywood sides using a guide to keep the saw straight. Cut the cleats to size, being sure to miter the front ends.
Lay the sides next to each other on a flat surface. Use a large square to draw lines across both boards to mark where the 1" cleats will hold up the shelves. Run a bead of glue along the cleats and nail each in place. Assemble the two sides together using a butt joint, wood glue and nails.
Measure the inside of the cabinet from outer corner to outer corner and cut the shelves to size using a circular saw. Tip: When cutting plywood with a circular saw, cut with the finished (good) side down so chips don't ruin the exposed surface.
Install the shelves to the inside of the cabinet by nailing each into the cleats and dress up the inside top edge using 1/2" quarter round. Cut 1" x 2" facing pieces to length to cover the front of each shelf.
For plain cabinet doors, measure the bottom opening and add 1/4" all the way around. Cut two doors this size.
Fill all nail holes with wood filler and let dry. Sand the entire piece and prime it if necessary. Once dry, paint or stain the piece as desired. Once completely dry, install the doors with chosen hinges and hardware.
Place the cupboard in the corner and make sure that it is secure. If the floor is uneven place a few shims under the edges to make it stable.
