Materials

Build steps

1. 1

   Measurement and Installation Site Check

   ≈ 15 min

   Measure the installation space for the multi-tier planter ladder (500×300×900mm). Check the width of the entrance area, ensure passage space of 600mm or more, and confirm door opening range.

   Measure

   W 500 mm

   MeasureSTEP 1 / 13

   Tip

   • Place so it does not interfere with the fan-shaped range when the entrance door opens.
   • Leave at least a 20mm gap between the wall and furniture for easier cleaning.
   • Avoid the boundary between entrance tile and floorboard; it causes instability.

   Watch out

   • Installation is not possible if the entrance space is insufficient for 500mm width; prior measurement is important.
   • Entrance is a high-traffic area; protrusions at foot level pose a risk of tripping.
2. 2

   Creating Cut List for Materials

   ≈ 30 min

   Cut the 19mm thick cedar board into front/back boards (19×120×900mm) ×16 pieces, side boards (19×120×300mm) ×16 pieces. Cut one bottom board from 12mm lauan plywood (12×262×462mm). Cut four corner posts from 2x4 lumber (38×89×900mm). Using home center's paid cutting service is convenient.

   Cut

   Use the in-store cut service

   CutSTEP 2 / 13

   Tip

   • Cedar boards vary greatly in knots and warping; select individually by hand.
   • The 900mm length for corner posts includes the height of front/back boards stacked (120×4=480mm) plus 20mm allowance.
   • When using cut service, you can request aligning the wood grain for better appearance.

   Watch out

   • The cut ends of cedar boards absorb water easily; apply preservative thoroughly in later steps.
   • 2x4 lumber actual dimensions are 38×89mm; specify '38×89' when ordering cuts, as nominal and actual sizes differ.
3. 3

   Sanding All Components

   ≈ 40 min

   Sand with #120 then #240 sandpaper in sequence. Cedar boards are soft and prone to warping and splinters, so sand the cut ends and surface carefully. Chamfer the edges of the 2x4 corner posts to make them smooth and prevent catching shoes or bumping legs.

   Sand

   #120

   SandSTEP 3 / 13

   Tip

   • Cedar grain is coarse; avoid sanding against the grain to prevent splinters.
   • Plane cut ends first with #120 sandpaper, then smooth with #240; skipping this causes uneven painting.
   • Using an orbital sander reduces time to about one-third; rental services are also available.

   Watch out

   • Sanding generates significant dust; do it in ventilated places such as balconies or garages.
   • Do not paint without removing dust after sanding; surface will be rough. Use an air duster or damp cloth to clean.
4. 4

   Erecting and Temporarily Fixing Corner Posts

   ≈ 25 min

   Stand the four 2x4 posts vertically, arranging them at the four corners of the workbench. Temporarily fix them with clamps to the workbench to level top and bottom. Use a level to check vertical alignment. Use a measuring tape to set the post spacing: 600mm front-to-back and 300mm left-to-right (inside dimension).

   Build the frame

   Tighten joints firmly

   AssembleSTEP 4 / 13

   Tip

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

   Watch out

   • If even one post is off vertical, the mounted boards will tilt after completion.
   • When measuring spacing, unify whether measuring inside or outside edges; inconsistency leads to 5-10mm error.
5. 5

   Attaching Front and Back Boards (Starting from Bottom)

   ≈ 40 min

   Place the first cedar board horizontally on the front bottom level. Apply wood glue to the corresponding junctions on the corner posts, then secure with 65mm coarse-thread screws: two on each side (four total per board). For the subsequent boards, stack with 5mm ventilation gaps (equal to one chopstick thickness) between them. Of the 10 boards, five go on the front and five on the back.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 5 / 13

   Tip

   • The 5mm ventilation gap prevents shoe moisture buildup; tightly joining boards causes mold.
   • Use chopsticks as spacers to uniformly maintain gaps.
   • Drill 4mm pilot holes in the corner posts before screwing to prevent wood splitting.

   Watch out

   • Driving 65mm screws without pilot holes may split the cedar boards; always drill pilot holes.
   • Over-driving screws causes indentations in the board surface; stop flush with the surface.
6. 6

   Attaching Side Boards (Left and Right)

   ≈ 35 min

   Attach 16 side boards (19×120×300mm) similarly with ventilation gaps. Attach five boards on each side. Adjust the front and back board positions first so the cut ends meet precisely at corners, then attach side boards. Measure diagonals (front-to-back across corners) with measuring tape and clamp to equalize them to prevent distortion.

   Build the frame

   Tighten joints firmly

   AssembleSTEP 6 / 13

   Tip

   • Diagonal length equality prevents parallelogram-shaped distortion; correct with clamps until equal.
   • Side boards are set inside front/back boards, so offset pilot hole positions slightly from the board edges.
   • For cleaner corners, cut corner beams at 45 degrees before assembly.

   Watch out

   • Misaligned ventilation slot positions between side and front/back boards spoils appearance.
   • Diagonal length errors exceeding 5mm cause difficulties fitting stored items smoothly.
7. 7

   Processing and Attaching Bottom Board

   ≈ 25 min

   Drill nine Ø20mm ventilation holes evenly arranged (3 vertical × 3 horizontal) in the 12mm lauan plywood bottom board (262×562mm). Space holes at least 50mm from edges and 100mm apart. Insert bottom board into the lower box frame, then fix to the four posts with 45mm coarse-thread screws.

   Drill a hole

   下穴 φ3.5mm

   DrillSTEP 7 / 13

   Tip

   • Ventilation holes are important to release shoe sole moisture; do not reduce number.
   • Use hole saws for clean holes; wood drills also acceptable.
   • The bottom side of the bottom board is not visible from outside, so no end tape is needed.

   Watch out

   • Warped bottom boards do not fit tightly to posts; check flatness first, and if curved, install reversed and fix with screws to straighten.
   • Placing ventilation holes too close to edges weakens strength; keep over 50mm from edge.
8. 8

   Final Right Angle and Diagonal Checks

   ≈ 15 min

   Confirm right angles and diagonals of the assembled box frame. Use a carpenter’s square to measure all four internal angles and check deviation from 90°. Measure the two diagonals with a tape measure and verify the difference is within 2mm. If misaligned, loosen screws, clamp to correct, and retighten.

   Inspect

   No wobble ✓

   InspectSTEP 8 / 13

   Tip

   • Diagonal difference indicates assembly accuracy; less than 2mm is acceptable for practical use.
   • Measure on a level floor surface to avoid measurement errors.
   • Check all screws by touch to ensure none are loose or insufficiently driven.

   Watch out

   • Ignoring distortion leads to poor lid (door) function after attachment.
   • Loose screws increase wobbling and risk structural failure under shoe weight.
9. 9

   Painting Preparation and Sanding

   ≈ 15 min

   Before painting, lightly sand entire assembly with #240 sandpaper and remove dust with damp cloth. Smooth edges around screw heads and cut ends. Use wood preservatives and mildew-proof paints suitable for outdoor use, such as Xyladecor or Osmo Color.

   Sand

   #240

   SandSTEP 9 / 13

   Tip

   • Cedar boards absorb paint heavily; two coats are required.
   • Apply generously to cut ends; fibers are exposed and absorbent.
   • Apply Watco Oil by rubbing in with cloth for even finish, better than brushing.

   Watch out

   • Rough sanding leads to paint unevenness and raised fibers.
   • Painting over dust causes rough surfaces.
10. 10

    First Coat Painting

    ≈ 30 min

    Apply Watco Oil or water-based paint to all surfaces. Use brush or cloth along wood grain in one direction. Let penetrate for 15–20 minutes, then wipe off excess with dry cloth. Paint ventilation gaps by brushing diagonally to avoid missed spots. Let dry naturally for at least two hours.

    Paint

    Watco oil / varnish

    PaintSTEP 10 / 13

    Tip

    • 'Apply and wipe' method with Watco Oil accentuates wood texture.
    • Paint pooled in ventilation gaps slows drying; wipe by rubbing.
    • Choose calm, dry days for outdoor painting to avoid dust settling and ensure smooth finish.

    Watch out

    • Failure to wipe off excess paint leaves tackiness for days; always wipe with dry cloth.
    • Applying thick coats causes uneven drying and later peeling; thin two coats is key.
11. 11

    Intermediate Sanding and Second Coat

    ≈ 25 min

    After the first coat dries, lightly sand with #320 sandpaper (intermediate sanding). Remove dust and apply a thinner second coat, wiping off excess as before. Allow 24 hours for complete curing.

    Paint

    Watco oil / varnish

    PaintSTEP 11 / 13

    Tip

    • Intermediate sanding smooths only paint fuzz without removing coats.
    • Two coats greatly improve wood protection; do not skip.
    • Keep painted item in dust-free place during drying.

    Watch out

    • Excessive sanding can remove first coat paint.
    • Skipping second coat halves protection, critical for moist entrance environments.
12. 12

    Adding Foot Pads and Waterproofing

    ≈ 15 min

    Attach felt pads or anti-slip rubber pads to bottom ends of corner posts. For entrances with moisture, rubber pads with water-repellent properties are recommended. For tile flooring, silicone pads offer better slip resistance.

    Fix to the wall

    Anchor to studs

    InstallSTEP 12 / 13

    Tip

    • Felt pads absorb water and get dirty; rubber or silicone are preferred for entrances.
    • Pads are essential on four corner posts; omitting central pads causes tilting.
    • Monitor for one week post-installation. Ventilate until paint fumes subside.

    Watch out

    • No pads risk floor damage and slipping on wet surfaces.
    • Some silicone pads have weak adhesive; use strong double-sided tape for added security.
13. 13

    Final Check and Shoe Storage

    ≈ 15 min

    Verify all screw tightness, uniform ventilation gaps, and paint finish. Check stability with a level. Adjust pad thickness as needed to achieve level. Avoid placing heavy items for one week until paint fully cures. Store shoes dry.

    Done!

    Done — nice work!

    DoneSTEP 13 / 13

    Tip

    • Dry wet shoes on door mats thoroughly before storage to prevent moisture buildup.
    • Ideal storage load is 80% of capacity; overfilling blocks ventilation.
    • Monthly ventilation by removing all shoes and using fans preserves durability.

    Watch out

    • Placing wet shoes before paint cures leaves shoe marks on paint.
    • Overloading and forcing shoes deforms boards.

Warnings

• ⚠️Use wood preservative paint for outdoor use (repainting once a year recommended).
• ⚠️Use stainless steel screws (iron screws will rust).
• ⚠️Drill pilot holes before screwing to prevent wood splitting.
• ⚠️When fixing to a wall, always locate a stud (do not fix to plasterboard only).
