Kitchen Remodel Debris by Square Footage — What Fits Where

A 12 × 14 kitchen remodel in a typical KC bungalow generates about 4.5 cubic yards of demo debris. A larger 16 × 18 kitchen in a newer home: closer to 7 yards. Add a floor tear-out and you're past 8. The math is consistent enough that we can size a remodel dumpster off square footage and material list alone. Here's how.

What gets removed in a typical KC kitchen tear-out.

Five debris categories, roughly in order of volume:

1. Cabinets and countertops — usually the biggest single category. Old plywood cabinets compress easier than people expect, but laminate-faced particleboard cabinets break apart unpredictably. Granite and quartz countertops are dense and heavy; tile-on-plywood counters are lighter but bulkier.
2. Drywall and plaster — KC has a lot of older homes (pre-1955) where the walls behind the cabinets are plaster, not drywall. Plaster is roughly 2x heavier than drywall by volume and harder on weight caps.
3. Flooring — only if you're tearing out. Tile-on-concrete is heavy. Hardwood is light but voluminous. Vinyl/LVT is the lightest.
4. Old appliances — fine to dispose if the refrigerator's freon has been professionally evacuated. More on allowed items.
5. Fixtures and trim — sinks, faucets, garbage disposals, base trim, soffits.

Real numbers from real KC kitchens.

From the loads we've actually hauled:

• 10 × 12 galley kitchen (apartment-sized): ~2.5 yards. 10 yard dumpster is plenty.
• 12 × 14 standard L-shaped: ~4–5 yards. 10 yard fits but tightly. We'd normally recommend the 12 yard for cushion.
• 14 × 16 island kitchen: ~5–6 yards. Solid 15 yard job.
• 16 × 18 large kitchen + adjacent breakfast area: ~7–8 yards. 20 yard.
• 20 × 22 great-room kitchen with wet bar: ~10–11 yards. 20 yard if the demo is tight; 30 if the floor goes too.

"Plaster doubles the load. Always ask your contractor what's behind the cabinets before sizing the dumpster."

Why the 20 is the safe default.

Most KC kitchen remodels are in homes between 1,500 and 2,800 sq ft, with kitchens in the 12 × 14 to 16 × 18 range. That puts the debris volume right at the 5–8 yard mark — a 20 yard handles it with comfortable margin and absorbs the inevitable extras (the cabinet someone forgot to mention, the pantry shelving, the half-bath drywall while you're at it).

Going down to a 15 or 12 saves a small amount of money and adds a real risk of a mid-job swap-out. We'd rather upsize.

When the 30 makes sense.

Three triggers: floor tear-out alongside the cabinets (especially tile on concrete); plaster walls instead of drywall in an older KC home; kitchen + adjacent room like a butler's pantry, mudroom, or great room being remodeled together.

The 30 yard shares the 20's footprint, so it fits the same driveways. The extra capacity is in the wall height, not the floor area.

What you can't throw in the kitchen-remodel dumpster.

The usual restricted list: refrigerators with freon (drain first or hire an HVAC tech), batteries (smoke detectors, under-cabinet motion sensors, anything with a lithium cell), paint cans (KC HHW takes them free), fluorescent tubes and CFLs. Full list of restricted items and KC alternatives.

One thing contractors get wrong.

Some KC contractors quote a smaller dumpster to keep the line-item price down and then arrange a "private haul" for the leftover debris in the back of a pickup. This usually ends up being illegal dumping at a relative's house. Push back: ask for the right size from the start. A 20 yard quoted upfront is cheaper and more honest than a 10 yard plus three pickup-truck "extras."
