Measure the available space. Proper proportion is essential to create an aesthetically appealing area. Cabinets that are too small will not serve the purpose, while ones that are too large will waste space. Height is normally 40 inches, depth 24 inches and widths vary depending on needs.
Draw a to-scale diagram of the space and intended layout. This will aid in determining the dimensions and location of each piece. Additionally, it will aid in material selection and the purchasing of cabinetry.
Buy lumber for the cabinet. There are approximately a dozen types of wood that are ideal for use in cabinet manufacturing. The specific wood you choose depends on its appearance and your budget.
Pine is an inexpensive type of wood used to create rustic style cabinets and furniture. It is noted for its knotted surface, but it is difficult to paint or stain. Cherry is often on the higher end of the cost scale and features a deep tone and smooth texture that fits well in modern rooms.
Measure and mark the lumber to the appropriate dimensions and cut with a circular saw. The corner cabinet will require a base, back, two side pieces and a top as well, as shelves if desired, each cut to your measurements.
The typical sink size is approximately 33 inches wide, 22 inches from front to back and a minimum of 8 inches deep. These measurements mean the sink cabinet must be at least 36 inches wide.
Construct the cabinet box starting with the base and attach the sides first. Apply a light layer of wood glue to both edges of the base and affix the sides. Add three or four nails spaced a few inches apart to each joint to add extra adhesion to the cabinet.
Attach the back piece with the same combination of wood glue and nails. Finish off the cabinet box with the top piece. Coat the ends of both sides and the back with wood glue. Install the top and finish with nails.
Paint or stain the surface of the wood if necessary. Generally, lower priced wood will come unfinished, which means it must be painted or stained once the cabinets are put together. Start by lightly sanding the surface using 300- or 320-grit sandpaper.
Roll or spray on the paint for the most streak-free finish. Stain application will vary a bit depending on the type of stain. Most types require the use of a brush or lint-free rag for proper application. Both paint and stain require two or three coats for full coverage.
Cover all newly painted surfaces with one or two coats of polyurethane. This product protects the wood and paint from damage and must be rolled on once the layers of paint have dried completely. The drying process takes anywhere from a few hours to overnight, depending on the type of paint being used. Follow manufacturer directions for best results.
Attach the cabinet face and hardware, including hinges, door knobs and drawer pulls. Each of these items is screwed into place. The hinge installation process for the cabinet door varies a bit depending on the type of hinge. Screw drawer pulls into the center of the drawer face, and door knobs onto the lower corner or along one side of the face.
