Wall Cabinet – 30 in. W × 21 in. H – W3021

ShopKitchens W3021 is a 30-inch-wide, 21-inch-high, 12-inch-deep frameless ready-to-assemble (RTA) wall kitchen cabinet. This intermediate-height upper cabinet can be considered when a 24-inch or 30-inch upper would not fit the planned wall run. Check actual room and appliance clearances before ordering.

W3021 wall cabinet specifications

Where does a 21-inch-high wall cabinet fit?

The W3021 is a shorter upper cabinet for layouts where a full-height wall cabinet is unsuitable. Measure the finished wall space and verify clearance around windows, soffits, appliances and neighboring doors. Do not assume a cabinet above a cooking appliance meets the appliance or ventilation manufacturer's clearance requirements.

Particle board versus plywood

Both cabinet-box materials are selectable in Shopify for W3021. Compare the actual configuration and cost before ordering; the chosen door style and finish also affect the exact variant price. The displayed price is for the selected variant, not every combination.

Do I need fillers or finished end panels?

Possibly. A complete cabinet run may require fillers for door operation or wall irregularities and finished panels on exposed sides. Handles, decorative panels and assembly are sold separately where applicable. Confirm the full layout rather than assuming those pieces are included with W3021.

How should I measure before ordering?

Measure the finished opening at multiple points, note obstructions and appliance specifications, and check the complete run including door swing and fitting pieces. Use the Wall Cabinets collection to compare related cabinet sizes and the Kitchen Measuring Guide to plan measurements. Verify the exact selected variant, its current price and delivery options at checkout.
