Build steps

  1. 1

    Measure and confirm installation location

    ≈ 15 min

    Measure the installation space for the garden planter stand (600×300×600mm). Confirm the width of the space, ensure a passage width of at least 600mm, and check the door opening range.

    Measure
    W 600 mm
    MeasureSTEP 1 / 13

    Tip

    • Place so it does not fall directly under rain gutters or cover drains.
    • Leave at least a 20mm gap between walls and furniture for easier cleaning.
    • Avoid the boundary between wood decking or soil and the ground (surface under the boards) as it causes instability.

    Watch out

    • Installation is impossible if the installation space is less than 600mm wide; measuring in advance is essential.
    • Outdoor locations often have many people passing by. A protruding placement at foot level poses a tripping hazard.
  2. 2

    Create the material cutting list

    ≈ 30 min

    Cut cedar boards 19mm thick into front/rear boards (19×120×600mm) ×10 pieces and side boards (19×120×300mm) ×10 pieces. Bottom board: lauan plywood 12mm thick (12×262×562mm) ×1 piece. Corner posts: 2×4 lumber (38×89×600mm) ×4 pieces. Using paid cutting service at home centers is convenient.

    Cut
    Use the in-store cut service
    CutSTEP 2 / 13

    Tip

    • Cedar boards vary greatly in knots and warping; select each board individually by hand.
    • The corner posts’ 600mm length includes the actual height of front/rear boards (120×4 = 480mm) plus 20mm margin.
    • When using cutting service, specifying grain alignment improves appearance.

    Watch out

    • The end grain of cedar boards easily absorbs water; apply preservative thoroughly in later steps.
    • The 2×4 lumber’s actual size is 38×89mm; specify '38×89' when requesting cuts (nominal and actual sizes differ).
  3. 3

    Sand all materials

    ≈ 40 min

    Sand using #120 then #240 grit sandpaper. Cedar boards are soft and prone to warping or splintering, so carefully sand ends and surfaces. Chamfer the 2×4 corner posts to create smooth edges to avoid snagging shoes or injuries.

    Sand
    #120
    SandSTEP 3 / 13

    Tip

    • Cedar fibers are coarse; sand with the grain direction to prevent splintering.
    • Use #120 grit on end grain to flatten, then #240 grit; skipping this causes coating unevenness.
    • Using an orbital sander can reduce sanding time to one-third; rental services are available.

    Watch out

    • Sanding produces large amounts of dust; work in ventilated spaces such as balconies or garages.
    • If dust is not removed before coating, the surface becomes rough; use an air duster or damp cloth to clean.
  4. 4

    Set up and temporarily fix the corner posts

    ≈ 25 min

    Stand the four 2×4 posts vertically and line them up at the four corners of the workbench. Temporarily fix with clamps to the workbench to maintain level at top and bottom. Use a level to check verticality. Measure spacing between posts to be 600mm front to back and 300mm left to right (internal dimensions).

    Build the frame
    Tighten joints firmly
    AssembleSTEP 4 / 13

    Tip

    • Check verticality on two planes (front and side) aiming for zero deviation with a level.
    • Concrete floors or cushioned floorings are uneven; place plywood underneath to create a flat work surface.
    • Align knots on all four posts in the same direction for better appearance by rotating during placement.

    Watch out

    • If even one post is off vertical, the assembled front, rear, and side boards will be tilted.
    • When measuring spacing with a tape, be consistent measuring either inside or outside edges of posts as it causes 5-10mm differences.
  5. 5

    Attach front and rear boards (starting from lower level)

    ≈ 40 min

    Position the first cedar board horizontally at the lowest front side, apply wood glue on both left and right corner posts, and fix with 65mm coarse-thread screws (2 per side, total 4 per board). For subsequent boards, leave a 5mm ventilation slit (width of one disposable chopstick) between boards, stacking upwards. Out of 10 boards, place 5 as the front and 5 as the back.

    Build the frame
    Tighten joints firmly
    AssembleSTEP 5 / 13

    Tip

    • The 5mm ventilation slit prevents moisture buildup in shoes; tightly joined boards cause mold.
    • Use chopsticks between boards to maintain uniform slit width.
    • Drill 4mm pilot holes on the posts side before screwing to prevent splitting.

    Watch out

    • Driving 65mm screws without pilot holes splits cedar boards; always drill pilot holes.
    • Over-driving screws causes surface indentations; drive screws flush with board surface only.
  6. 6

    Attach side boards (left and right)

    ≈ 35 min

    Attach ten side cedar boards (19×120×300mm), five on each side, similarly with ventilation slits. Adjust front and rear boards positioning first to make end grains align perfectly at corners. Measure diagonal length (front-to-back diagonals) with a tape measure and fix while ensuring both diagonals are equal.

    Build the frame
    Tighten joints firmly
    AssembleSTEP 6 / 13

    Tip

    • Unequal diagonals cause a parallelogram distortion; use clamps to correct until equal.
    • Side boards fit inside front and rear boards, so offset pilot hole positions slightly away from edges of front/rear boards.
    • For better corner fitting, pre-cut the corner boards at 45° and attach.

    Watch out

    • Align ventilation slits on side boards with front/rear boards; otherwise appearance is inconsistent.
    • More than 5mm diagonal error results in poor fit for stored items.
  7. 7

    Process and attach bottom board

    ≈ 25 min

    Drill nine 20mm diameter ventilation holes (arranged 3 vertically × 3 horizontally) evenly on the 12mm lauan plywood bottom board (262×562mm). Keep holes at least 50mm from edges and 100mm apart from each other. Insert the bottom board into the lower box and fix it to the four corner posts with 45mm coarse-thread screws.

    Drill a hole
    下穴 φ3.5mm
    DrillSTEP 7 / 13

    Tip

    • Vent holes are essential to release moisture from shoe soles; do not reduce number.
    • Use a hole saw for clean holes; wood drill bits also acceptable.
    • No need to apply edge tape on bottom side as it is not visible from outside.

    Watch out

    • Warped bottom boards will not fit snug against posts; check flatness first. If warped, reverse orientation and secure with screws to flatten.
    • Placing holes too close to edges weakens strength; keep at least 50mm margin.
  8. 8

    Final check of right angles and diagonals

    ≈ 15 min

    Check right angles and diagonals of the assembled box. Measure all four internal corners with a carpenter's square and check deviations from 90°. Measure the two diagonals with a tape and confirm their difference is within 2mm. If misaligned, loosen screws, clamp to correct, and retighten.

    Inspect
    No wobble ✓
    InspectSTEP 8 / 13

    Tip

    • Diagonal difference is an indicator of assembly accuracy; within 2mm is acceptable practically.
    • Measurement can be skewed if floor is not level; confirm on flat ground.
    • Check for any loose screws by feel.

    Watch out

    • Leaving distortions causes lid opening and closing difficulties.
    • Loose screws pose risks of wobbling and collapse under shoe weight.
  9. 9

    Prepare painting surface and sanding

    ≈ 15 min

    Lightly sand the entire unit with #240 grit sandpaper before painting, then remove dust with a damp cloth. Also even out screw head areas and end grain differences. Use outdoor coatings like Xyladecor or Osmo Color which are easy to use.

    Sand
    #240
    SandSTEP 9 / 13

    Tip

    • Cedar absorbs paint heavily; plan on applying two coats.
    • Apply more paint to end grain as fibers are exposed and absorbent.
    • For Xyladecor, rub in with a cloth rather than brush for even finish.

    Watch out

    • Rough sanding before coating causes uneven paint and fuzz.
    • Painting without dust removal results in rough surface.
  10. 10

    First coat painting

    ≈ 30 min

    Apply Xyladecor or water-based paint over all surfaces with a brush or rag, following wood grain in one direction. Let it soak for 15-20 minutes, then wipe off excess with a dry cloth. Apply paint into ventilations slits at an angle to avoid missed spots. Let dry naturally for at least two hours.

    Paint
    Watco oil / varnish
    PaintSTEP 10 / 13

    Tip

    • The 'apply and wipe off' method for Xyladecor enhances wood texture.
    • Paint pooling in slits delays drying; wipe those areas carefully.
    • For outdoor work, ensure ventilation and open windows to control vapor odor.

    Watch out

    • Forgetting to wipe off leaves tacky residue for several days.
    • Applying thick coats causes uneven drying and later peeling; thin two-coat application is essential.
  11. 11

    Light sanding and second coat painting

    ≈ 25 min

    Once the first coat dries, lightly sand the surface with #320 sandpaper (intermediate sanding). Remove dust and apply the second coat thinner than the first, wiping off excess similarly. Allow 24 hours for full curing.

    Paint
    Watco oil / varnish
    PaintSTEP 11 / 13

    Tip

    • Intermediate sanding lightly removes fuzz without removing the paint film.
    • Two coats significantly improve wood preservative effectiveness; do not skip.
    • Keep painted item in a dust-free environment during drying.

    Watch out

    • Excessive sanding can peel off the first coat.
    • Skipping the second coat reduces preservative effect by half; very important for outdoor installations.
  12. 12

    Attach leg pads and waterproofing

    ≈ 15 min

    Attach felt pads or anti-slip rubber pads to the bottom ends of corner posts. If placing directly on the ground, raise the stand by about 10cm using bricks or blocks. For tiles, silicone pads prevent slipping.

    Fix to the wall
    Anchor to studs
    InstallSTEP 12 / 13

    Tip

    • Felt pads absorb water and get dirty; rubber or silicone are recommended for outdoor use.
    • Pads are essential on all four corner posts; omitting any causes tilting.
    • Observe for a week post installation; continue ventilation until paint odors dissipate.

    Watch out

    • Without pads, floors can be scratched and wet floors become slippery.
    • Some silicone pads have weak adhesive; using strong double-sided tape is safer.
  13. 13

    Final check and shoe storage

    ≈ 15 min

    Confirm all screws are tightened, ventilation slits are even, and paint is uniform. Check for wobbling with a level; adjust pad thickness as needed to level. Avoid placing heavy items for one week until paint fully cures. Store shoes dry.

    Done!
    Done — nice work!
    DoneSTEP 13 / 13

    Tip

    • Wipe wet shoes with cloth before storing to prevent moisture buildup.
    • Ideal storage capacity is about 80% of maximum; overfilling obstructs ventilation.
    • Monthly airing (removing all shoes and using fans) prolongs lifespan.

    Watch out

    • Placing wet shoes on paint before curing leaves shoe-shaped marks.
    • Overloading causes board deformation.

Warnings

  • ⚠️Wood preservative coating is essential for outdoor use (recoating recommended annually).
  • ⚠️Use stainless steel screws (iron screws will rust).
  • ⚠️Drill pilot holes before screwing to prevent wood splitting.
