I turned a pile of old kitchen cupboard doors into a modern, stain-finished timber headboard—an upcycled build that looks custom. My sister wanted a headboard for her granddaughter’s room at her place, but she didn’t want it painted. She needed a piece she could dress with playful kids’ bedding, yet still feel right for adult guests.

Reclaimed doors kept costs low and gave me solid timber to work with. Chunky posts frame the panel for a sturdy, classic look. A hidden rear brace adds strength for easy moving. I chose a warm cedar stain with satin polyurethane, which highlights the grain and hides everyday scuffs. The subtle two-tone detail in the routed profiles adds depth without locking you into one colour scheme. Style it sweet and fun for sleepovers, then switch to crisp linens for a calm, grown-up guest room.

DIY Headboard from Recycled Kitchen Cupboard Doors

Materials

• Recycled kitchen cupboard doors (mine were 20 mm thick)
• Two timber posts for the sides (approx. 90 mm × 90 mm; length to suit your bed height)
• Two rails for top and bottom slots (I used 110 cm to suit a single bed frame at 107 cm)
• 100–180 grit sanding discs for a random-orbit sander
• Degreaser (sugar soap or bleach spray), sponge scourer, clean rags
• Wood glue
• Nail Gun with battery or compressor
• Wood router
• 75–100 mm wood screws (for the rear support beam)
• Cedar wood stain (or favourite timber stain)
• Oil-based satin polyurethane (at least two coats)
• Recycled hardwood fence post (approx. 100 mm wide) for rear support beam
• Wood filler (optional), furniture pads (optional)

Tools: Tape measure, combination square, clamps, table saw (or circular saw with guide), router with straight bit and round-over bit, hammer and chisel, nail gun, drill/driver, countersink bit, PPE (mask, eye and ear protection).

Plan your size and layout

Measure the bed base and mattress width. Mine needed to clear a 107 cm wide single bed. I allowed an 8 cm reveal above the doors to visually “cap” the panel and give room for bedding. Decide on your headboard height so that pillows sit below the panels.

Clean up the cupboard doors

I removed every hinge, handle and catch and saved the hardware for other projects. Years of kitchen life left a greasy film, so I sprayed the surfaces with sugar soap (bleach spray also works), let it sit, and scrubbed with a sponge scourer. After a wipe-down and full dry, I sanded with 100 grit, then 180 grit for a smooth finish.

The grooves were fiddly to sand by hand, so I leaned into a two-tone look—sanding the flats clean and leaving a touch of depth in the profiles for contrast.

Make the posts and grooves

The side posts are chunky—90 mm × 90 mm—and heavy, which gives the headboard a solid, classic feel. I measured the length of the doors and added 8 cm to leave that top reveal.

Because my doors are 20 mm thick, I cut a 20 mm-wide, 20 mm-deep groove centred along the inside of each post.

I used the table saw for multiple passes, then cleaned the groove with a chisel for a snug fit.

Cut the top and bottom rails

To hold the doors in place, I cut two rails at 110 cm (to suit the 107 cm bed width). I repeated the groove process—20 mm wide by 20 mm deep—so the doors could slot into both rails. A square fit here keeps the whole panel neat, so take a moment to check everything is straight.

Stain the doors

Staining the doors before assembly is faster and cleaner. I brushed on cedar stain, wiped back the excess, and let the colour settle. It looked a bit flat at first, but the stain always warms up once the clear coat goes on—don’t panic if yours does the same.

Assemble the headboard panel

With all grooves cut, I dry-fitted the doors into the posts and rails. When I was happy, I glued every slot, seated the doors, and fixed them from the back with a nail gun for extra strength. Work on a flat surface and clamp as you go to keep the panel straight. I got so involved that I did not take a picture of the top and bottom beams.

Add a rear support beam

Those posts are hefty, so I added a hidden brace across the back to stop any racking during moves. I used a 100 mm-wide recycled hardwood fence post as the beam. It was 20 mm thick, so I routed a 20 mm recess into each post to house the beam.

Clamping both posts together and running a straight fence made this step quick. I pre-drilled and drove long wood screws through the posts into the beam. It’s on the back, so the timber colour mismatch doesn’t matter.

Dress the posts with caps

The tops looked a bit plain, so I made simple stacked caps: two 140 mm × 140 mm squares and two 90 mm × 90 mm squares. I rounded over the edges with a router for a softer look. I glued the first square and fixed it with two countersunk screws so the next square sits flush. The smaller top squares were glued and pinned with the nail gun.

Final sanding, stain and clear coat

I sanded the new caps and any bare timber, then stained to match the doors. For protection, I rolled on two coats of oil-based satin polyurethane, brushing the grooves and edges. A light de-nib between coats with 320 grit keeps the finish smooth and helps the cedar colour pop.
