Bathroom remodels look small but produce surprisingly heavy debris — old cast-iron tubs, tile, plaster. Here’s the sizing math that catches the weight before it catches you.
Quick answer by bathroom type
- Half bath / powder room: 10-yard dumpster
- Standard full bath (5×8 to 8×10): 10-yard or 15-yard
- Master bath with separate tub and shower: 15-yard or 20-yard
- Multiple bathrooms in one project: 20-yard
What bathroom demo produces
A complete bathroom demo includes some or all of: tub or shower surround, toilet, vanity and sink, mirror and lighting, floor tile and backerboard, wall tile (often), drywall behind tile, plumbing fixtures, exhaust fan, and miscellaneous trim.
By volume, this produces 6 to 10 cubic yards of debris — well within 10-yard capacity. The challenge is weight, not volume.
Weight estimate by component
- Cast-iron tub: 250 to 500 lbs (heavy — older tubs are heavier)
- Steel tub: 100 to 150 lbs
- Acrylic or fiberglass tub: 50 to 100 lbs
- Standard toilet: 90 lbs
- Vanity with sink: 100 to 200 lbs
- Floor tile (40 sq ft + backerboard): 250 to 350 lbs
- Wall tile (60 sq ft + backerboard): 300 to 400 lbs
- Drywall removal (full bath): 200 to 400 lbs
- Plaster walls (older homes): 600 to 1,000 lbs
Total typical full-bath demo weight: 1,500 to 2,500 lbs (under 1.5 tons). A 10-yard’s 1 to 2-ton allowance is usually fine. The exception: master baths with cast-iron tubs and full plaster walls in older homes can push 3,500 to 4,000 lbs, which exceeds a 10-yard allowance.
When to size up to a 15-yard
- Master baths with separate tub AND shower being demoed
- Cast-iron tub removal (heavy)
- Full plaster wall demo in pre-1960s homes
- Bathrooms with extensive built-in storage or linen closets being removed
- Reno that extends to adjacent closet or hallway
Common bathroom-specific dumpster considerations
Cast-iron tub disposal
Old cast-iron tubs are extremely heavy — sometimes 500+ lbs. Many municipalities accept cast iron for scrap metal recycling and it’s worth $0.10 to $0.15 per pound. If you’re tearing out a cast-iron tub, consider a separate scrap metal pickup before the dumpster arrives — saves on weight overage and recovers $30 to $75.
Plaster vs. drywall
Bathrooms in homes built before 1960 typically have plaster walls, not drywall. Plaster is 2 to 3 times heavier per square foot than drywall, and the lath behind it adds weight. If you’re remodeling an older bathroom, double your weight estimate for wall demolition.
Asbestos in older bathrooms
Floor tile, mastic, and pipe insulation in pre-1980s bathrooms can contain asbestos. If your home is from this era, get materials tested before demo. Asbestos can’t go in a dumpster — it requires licensed abatement.
Old fixtures with mercury or lead
Pre-1980s fluorescent fixtures may contain mercury. Old plumbing solder may contain lead. Most municipal hazardous waste programs accept these — don’t put them in the dumpster.

10-yard dumpster, 7-day rental, 1-2 ton allowance, mid-size market: $275 to $400 all-in. For most full bathrooms, this covers the entire demo with weight to spare.
Master bath remodels with tub removal and tile demolition often justify a 15-yard at $325 to $475 — the extra $50 to $75 is much cheaper than a weight overage charge.
Frequently Asked Questions
Do I need a dumpster for a bathroom remodel?
For a full demo, yes — bathroom debris is too much for residential trash service. For a refresh (paint, fixtures, hardware only), you might get by with contractor bags.
Can I put a toilet in a dumpster?
Yes, in most areas. Toilets are accepted as standard household debris by most haulers. Drain the tank and bowl before disposal.
How much does a bathroom remodel dumpster cost?
10-yard for a standard bathroom: $275 to $400 for the rental. 15-yard for a master bath: $325 to $475. Add tax and surcharges.
Is a 10-yard dumpster too small for a bathroom?
For most full bathrooms, a 10-yard is the right size. Only consider 15-yard for master baths with cast-iron tubs, plaster walls, or extensive built-ins.
