Best unfinished 18x30 kitchen wall cabinets under $80

Top pick: the Hampton Bay 18 x 30 ready-to-assemble wall cabinet in unfinished. It's the closest thing to what you asked for: the right width and height, a bare surface you can paint or stain to match your kitchen, and it comes flat-packed so it's easier to carry and to finish before hanging. The trade-off is assembly — if you'd rather not build it, the assembled Hampton Bay version is the same footprint and ready to hang straight out of the box.

Who the others suit:

• W1830 wall cabinet — for anyone who wants a solid birch/maple box and doesn't mind a factory finish.
• Shaker PVC white wall cabinet — for a damp room or a quick, wipe-clean install where painting isn't the plan.
• Hampton Bay unfinished oak — the pick if you want real oak grain to stain rather than paint; it sits just over your cap.

Check the door style and depth against your run before ordering — depths vary between these.
