Are you looking to maximize the space in your kitchen or bathroom? Triangle corner cabinets are an excellent way to make the most of your available space, but building one can seem like a daunting task. Whether you're a seasoned DIY enthusiast or a beginner taking on your first cabinet project, we've created this comprehensive guide to help you build your own triangle corner cabinet plans.

First, let's discuss why triangle corner cabinets are such a smart choice. Their unique shape allows them to fit into places in your home where traditional cabinets don't fit, helping to eliminate wasted space. These cabinets are also highly customizable, allowing you to choose the size, finish, and layout that best suit your needs and style.

Materials and Tools You'll Need
Before you start building, it's essential to gather all the necessary materials and tools to ensure a smooth construction process. Here's a list of what you'll need:

Materials:
- Plywood (MAX, sanded) - 3/4" thick
- Solid wood or laminate - for door and drawer fronts
- Hinge bolts and screws
- Drawer slides and hardware
- Paint or stain and sealant (optional)

Tools:
- Circular saw
- Jigsaw
- Drill
- Screwdriver bits (various sizes)
- Tape measure
- Speed square
- Clamps
- Sandpaper (various grits)
Design and Measure Your Triangle Cabinet

Before you start cutting any wood, you'll need to determine the size and shape of your triangle corner cabinet. Measure the available space in your corner, keeping in mind that you'll need a few inches of clearance for the door and drawer to open fully.
Most triangle corner cabinets are designed with right angles, making them easy to build and fit into standard room corners. However, you can also create cabinets with 45-degree angles for a more unique look. Once you've determined the size and shape of your cabinet, it's time to create your cut list and get started.
Create Your Cut List

Now that you have your design and measurements, you can create a cut list to ensure you have all the necessary pieces to build your cabinet. Here's a basic cut list for a right-angle, 12" wide triangle corner cabinet:
| Part | Quantity | Width | Height | Depth |
|---|---|---|---|---|
| Top | 1 | 12 in | 12 in | 12 in |
| Right side | 1 | 12 in | 36 in | 12 in |
| Left side | 1 | 9 in | 36 in | 12 in |
| Back | 1 | 12 in | 36 in | 12 in |
| Bottom | 1 | 12 in | 12 in | 12 in |
| Door | 1 | 12 in | 19 in | 1.5 in |
| Drawer front | 1 | 9 in | 5 in | 1.5 in |









Build the Cabinet Box
With your cut list in hand, you can begin assembling the cabinet box. Start by cutting your plywood pieces according to your cut list using a circular saw or jigsaw. Once you have all your pieces, it's time to begin assembly:
- Attach the back panel to the top and bottom pieces using wood glue and screws.
- Attach the right and left side panels, ensuring that the cabinet maintains a right-angle shape.
- Attach the bottom panel to the back, right, and left side panels.
Install the Shelves and Drawer
Now that your cabinet box is complete, it's time to install the shelves and drawer. Start by measuring and cutting your shelf material to fit the width and depth of your cabinet box. Attach the shelves to the back and side panels using wood glue and screws.
Next, install your drawer slides according to the manufacturer's instructions. Once the slides are in place, attach the drawer front to the drawer box using hinge bolts. Ensure that the drawer opens and closes smoothly before moving on to the next step.
Attach the Door
With the drawer in place, it's time to attach the door to the front of your cabinet box. Measure and cut the door according to your cut list, and attach the hinge bolts to the door and cabinet box. Ensure that the door opens and closes smoothly, and make any adjustments as needed.
Finally, paint or stain your cabinet to match your desired finish. Allow the paint or stain to dry completely before reassembling the cabinet and installing it in its permanent location.
