Today I’m showing you the DIY 3-drawer base cabinets and how they can be made to work for you!

Is your garage shop a mess?  Need better storage?  The DIY Garage Cabinets System is what you’ve been looking for.  Mix and match cabinets and drawers to build the storage YOU need. 

I designed and built these garage shop cabinets over the course of a year.  My old store-bought cabinets fell apart on me, and I wanted something better.  So I built the new system one piece at a time, with future expansion in mind. 

DIY 3-Drawer Base Cabinets: The Foundation of our Garage Cabinets System

Before we dig into the DIY 3-drawer base cabinets, a word about the system I’ve built. It includes five different components that can be mixed and matched to make hundreds of combinations.  I made each piece either 15, 30 or 60 inches so you can build in sets of 30″.  Here are the cabinets that I came up with:

• 30″ Wall Cabinet with 5 Storage Options
• 30″ Base Cabinet with Doors
• 15″ 5 Drawer Base Cabinet
• 60″ Pegboard Hutch
• 30″ 3 Drawer Base Cabinet

The components could be made separately, but having all 5 really gives you custom options.  And to save you some money I’ve put them all in a bundle.  You save 30% when you buy the DIY Garage Cabinet Bundle.  You’ll also get a few free bonuses including some sample layouts to get your creative juices flowing.

How to Build DIY 3-Drawer Base Cabinets

Building your own cabinets might seem intimidating, but with the right approach and some helpful tips, you can create professional-looking storage solutions for your workshop or garage. These sturdy 3-drawer base cabinets are built from Baltic birch plywood and feature smooth-operating drawers with continuous grain fronts.

The Build Process for our DIY 3-Drawer Base Cabinets

1. Break Down the Plywood Sheets

Start by cutting full sheets into manageable pieces. Working on the floor with rigid foam underneath makes this easier—you can crawl on top of the sheets to reach across large panels.

Pro tip: Use sticky notes to label each piece with a number and list what parts you’ll cut from it. Mark factory edges with arrows since they’re typically straight and square. This organization prevents costly mistakes when working with efficient plywood layouts.

2. Cut Cabinet Parts to Final Size

Take your rough-cut pieces to the table saw and cut them slightly oversized first, using the factory edge against the fence. Then make a final pass to remove a small sliver, giving you clean, fresh table saw edges on all sides. This makes joinery much easier and ensures tight-fitting assemblies.

Parts to cut:

• Cabinet sides
• Cabinet bottoms
• Top supports
• Back supports

3. Cut Toe Kick Notches

Mark the inside lower corners of your cabinet sides, then cut notches for the toe kicks. A combination square makes this layout repeatable. These cuts don’t need to be perfect—a jigsaw works fine since they’ll holding the toe kick.

4. Cut Support Pieces to Length

The supports must be exactly the same size as the cabinet bottom, or your drawers won’t fit properly. Use a stop block on your miter saw for consistent, repeatable cuts. Always square the end first, then cut your parts and verify the first piece before making the rest.

5. Add Pocket Holes

Drill pocket holes in the appropriate pieces for cabinet assembly. A dedicated pocket hole jig makes this quick and consistent.

6. Assemble the Cabinet Carcass

Use a large, flat surface for assembly. A combination square helps maintain consistent offsets for the bottom piece. Attach the bottom with pocket screws, then flip to add the top supports. Add back supports butted against the bottom and upper support—these provide wall-mounting points and prevent racking.

7. Install the Back Panel

Check that your cabinet is square by measuring diagonals—they should be within 1/32″ of each other. Cut a back panel to size and attach it with glue and finish nails. This locks everything into place and adds rigidity.

8. Build the Drawer Boxes

Cut drawer sides to match the length of your drawer slides. For drawer fronts and backs, use this formula: cabinet interior width minus 1″ (for slides). Now subtract the thickness of two pieces of your drawer material and you have your measurement. Pro tip: Make them about 1/32″ smaller than calculated to make your drawer slides smoother and avoid binding.

Assemble drawer boxes with pocket screws, then add glued and nailed ¼” plywood bottoms. Keep nails ⅜” from edges, then add a chamfer with a handheld router to hide the plywood edge.

9. Install Drawer Slides

Lay the cabinet on its side so you’re not fighting gravity. Use spacers and measurements from your plans to position the slides consistently on both sides. This ensures drawers operate smoothly.

10. Mount Drawers with Spacers

Install drawers starting with the bottom one resting on ¼” plywood. Pull slides flush with the front and secure with screws. Use spacers on top of each drawer to position the next one up.

11. Create Continuous Grain Drawer Fronts

Cut a single large piece of plywood to cover the entire cabinet front with appropriate reveals. Set your saw blade height to match the drawer front height and rip the panel into three pieces. The saw kerf creates perfect ⅛” reveals between fronts while maintaining continuous grain flow.

12. Finish and Install Drawer Fronts

Sand and finish the fronts with polyurethane. Pre-drill hardware holes before mounting. Use a scrap piece screwed to the cabinet bottom as a ledge to support each front during installation. Align for consistent reveals, temporarily screw through hardware holes, then add permanent screws from inside the drawer box.

Safety note: Never extend more than one drawer at a time while the cabinet is on your bench—it can tip over.

13. Add Hardware and Final Touches

Drill through drawer boxes for hardware installation. Consider adding reinforcement to the base for optional leveling feet if needed for your space.

Tips for Success with your DIY 3-Drawer Base Cabinets:

• Stay organized: Label everything and track your cuts
• Cut oversized first: Always make a fresh final cut for clean edges
• Use stop blocks: They ensure consistent, repeatable cuts
• Check square early: Measure diagonals before adding the back panel
• Work from bottom up: Install drawer fronts starting at the bottom
• One drawer at a time: Reduces risk and makes alignment easier

These DIY 3-Drawer Base Cabinets provide excellent storage for workshop supplies and can be customized to fit your specific space and needs.
