A wall cabinet with a tambour door is a useful intermediate woodworking project: it hides clutter without needing the door swing clearance of a conventional cabinet. The difficult parts are not the box itself, but keeping the cabinet square and making a tambour that rolls smoothly instead of binding. This plan produces a cabinet about 24 inches wide, 30 inches high, and 8 inches deep. Adjust the dimensions to suit your wall, but keep the construction sequence the same.

Plan the cabinet and choose materials
Use 3/4-inch plywood for the cabinet sides, top, bottom, and shelf. Baltic birch is the easiest to work with because its edges are consistent and its face is relatively flat. Cabinet-grade hardwood plywood also works. Avoid construction plywood; its voids and uneven layers make accurate joinery difficult.
The tambour consists of narrow slats joined by flexible cloth on the back. For a 24-inch-wide cabinet, use slats about 1 1/4 inches wide and 1/4 inch thick. You will need roughly 24 slats for a door opening around 22 1/2 inches high. Make a few extra slats so you can reject pieces with tear-out or bad grain.
| Material | Advantages | Trade-offs |
|---|---|---|
| Baltic birch plywood | Flat, stable, clean edges | Costs more than construction plywood |
| Hardwood plywood | Good appearance and moderate cost | Core quality varies by supplier |
| Solid wood tambour slats | Can match the cabinet and look refined | Requires consistent milling and can move with humidity |
| Commercial tambour kit | Saves time and usually rolls smoothly | Less control over slat width, wood, and final dimensions |
Gather a table saw or track saw, router, clamps, square, drill, and random-orbit sander. A flush-trim router bit set is useful for cleaning templates and repeated parts, but it is not essential. You will also need wood glue, 120- and 180-grit abrasive, 1/4-inch round-over and straight router bits, tambour cloth, and a finish.
Cut and prepare the cabinet parts
For the example dimensions, cut two sides at 30 by 8 inches, a top and bottom at 24 by 8 inches, and a shelf at 22 1/2 by 7 1/2 inches. Cut a 1/4-inch plywood back at 24 by 30 inches. The back overlays the rear of the cabinet and helps prevent racking.
Before cutting, mark the best-looking plywood faces. Keep those faces outward and use the same reference edge when measuring every part. A one-sixteenth-inch error repeated across several cuts can leave the cabinet visibly out of square.
Cut a 1/4-inch-wide by 1/4-inch-deep rabbet along the rear inside edge of each side, top, and bottom to receive the back. If you do not have a router, screw the back on later, but check the diagonals carefully. Sand the plywood faces lightly with 180 grit; do not aggressively round the front edges, because the tambour tracks need a clean, consistent opening.
Assemble a square cabinet box
Dry-fit the top, bottom, and sides before applying glue. Measure both diagonals across the front of the box. They should match within 1/16 inch. Spread glue on the mating edges, clamp the box, and check the diagonals again. Drive 1 1/4-inch brads or screws from the sides into the top and bottom if the fasteners will be hidden by the finish.
Install the shelf after the main box is stable. A shelf positioned 10 to 12 inches below the top works for small containers and folded items. Use adjustable shelf pins if you expect the contents to change. A 5mm shelf pin jig makes straight rows, but fixed dados are cheaper and stronger when the shelf height is known.
Glue or screw on the back only after the box is square. Measure the diagonals one final time before the fasteners are fully tightened. A cabinet that is slightly skewed may still look acceptable, but its tambour will reveal the problem by rubbing on one side.
Make the tambour slats
Mill the slats to a consistent 1/4-inch thickness. Rip them all to the same width, then cut them about 1/2 inch shorter than the clear opening height. The door needs clearance to travel through the side tracks and curl into the top pocket. For a 22 1/2-inch opening, begin with slats around 22 inches long and test-fit the assembly.
Round the front face of each slat with a 1/4-inch round-over bit or a carefully set plane. Leave the rear face flat so the cloth can sit evenly. Sand the rounded faces before assembly. Do not round the two outer edges excessively; they must remain guided by the tracks.
Lay the slats face down on a flat surface with a small, even gap between them—about 1/32 inch is usually enough. Tape a straightedge across the ends to keep the row aligned. Glue tambour cloth to the backs using a flexible adhesive recommended for fabric and wood. Apply a thin, continuous coat, then press the cloth flat without soaking it. Let it cure fully under a board and light weights.
Cut the tracks and test the door
The side tracks guide the tambour down the front, around the top, and into a storage pocket. Rout a 1/4-inch-wide by 3/8-inch-deep groove in each side, starting at the bottom of the opening and curving toward the cabinet interior at the top. A simpler option is to install separate hardwood guide strips: two vertical strips at the sides and two curved strips forming the upper path.
Make a full-size cardboard template of the track before cutting wood. The curve should be gradual, with no sharp corner. A tambour bends across its slat joints, but it cannot negotiate a sudden turn. Leave at least 1/8 inch of total clearance between the slat length and the track spacing.
Test the unfinished door in the tracks. It should move with one hand and stay aligned without force. If it binds, look for a tight track, uneven slat spacing, proud glue, or a cabinet that is out of square. Do not solve binding by sanding random slats; find the restriction first.
Finish, mount, and adjust
Remove the door and finish the cabinet and slats separately. Water-based polyurethane dries quickly and keeps light woods pale. Oil-based polyurethane adds warmth but takes longer to cure. Apply two or three thin coats, sanding lightly between coats. Keep finish out of the tracks, or sand the tracks slightly wider after curing.
Mount the cabinet into wall studs whenever possible. For a 24-inch cabinet, use two structural screws through the back or a French cleat made from 3/4-inch plywood. Do not rely on drywall anchors alone if the cabinet will hold dishes, tools, or books. A stud finder with a magnetic level helps locate screws and keep the cabinet level.
Install a small pull or finger recess on the lowest slat. If the door rattles, add thin felt to the track entry points. If it creeps open, check that the cabinet is level and that the tracks are parallel. Seasonal humidity can swell solid-wood slats, so leave a little clearance and never glue the door into its tracks.
