Things You'll Need
1/8-inch drill bit
1 1/2-inch grabber screws
Do you need a sink cabinet in your laundry room? Most cabinet shops will charge around $300 for a sink cabinet. You can build one yourself and save money. Sink cabinets cannot have an adjustable shelf because the cabinet needs to house the pipes for the sink. Most laundry sink cabinets are 30 inches wide, 24 inches deep and 34 1/2 inches tall.
Cutting Out The Parts
Cut out two pieces of 3/4-inch melamine to 23 1/4 inches by 34 1/2 inches using a table saw. Mark these two pieces as sides on the edge where they have been cut using a pencil. You will have a right and left side.
Cut out the bottom for your cabinet using a table saw. You must subtract 1 1/2-inches from the width because the sides and bottom will butt-joint together. If your overall cabinet width is 30 inches, you need to cut your bottom section at 23 1/4 inches by 28 1/2 inches.
Cut the cabinet back using a table saw. This section should be 34 1/2 inches tall. The width will be whatever width you want your cabinet. Label this piece as the back.
Cut two stretchers to run along the top of the cabinet in the front and back that will allow the counter-top to be fastened. The stretchers are 4 inches wide and the same length as the cabinet bottom width. For a 30 inch wide cabinet, cut the stretchers 4 inches by 28 1/2 inches.
Cut two doors for your cabinet. If your cabinet is 30 inches wide, cut two pieces 14 3/4 inch by 34 inches.
Band the front of the cabinet parts along the 3/4-inch edges using pre-glued edge banding tape. This tape can be bought at al home improvement store. The tape just sticks to the edge of the melamine side. Band around each edge of the doors.
Attach Cabinet Sides to Bottom
Align one of the cabinet sides with the bottom. The cut edge of the bottom should butt joint into the cabinet side. Place a small amount of carpenter's glue along the joint.
Drill four 1/8-inch pilot holes through the sides into the cabinet bottom. This will allow you to place the grabber screws through the hole and fasten the bottom section to the sides.
Fasten the opposite side on the same manner.
Attach Stretchers and Back to Cabinet Sides
Place one stretcher at the top of the cabinet between the two sides. Align it with the front of the cabinet. Place a small amount of glue between each joint and fasten them together using a power drill and grabber screws.
Place the second stretcher at the back of the cabinet at the top of the sides. Apply a small amount of glue in the joint and fasten the stretcher to the sides using a power drill and grabber screws.
Place a small amount of glue around the back of the cabinet. Attach the cabinet back using a power drill and grabber screws.
Attach hinges to the cabinet doors using the screws provided with the hinge. Hold the door on the cabinet in position and screw the hinge and door assembly to the cabinet side.
