What size dumpster do I need for a bathroom remodel?

Usually a 10 yard container for one bathroom, 10 to 15 yards for a full gut with lots of tile, and 15 to 20 yards for two bathrooms.

How much does bathroom demolition cost?

Angi puts professional bathroom demolition at about $300 to $3,500, or roughly $8 to $20 per square foot.

Can I put a cast iron tub in a dumpster?

Often yes, but it is very heavy. Many homeowners sell it to a scrap metal recycler instead, which saves weight in the container.

Do I need to test for asbestos before a bathroom remodel?

In older homes, yes for suspect materials such as old floor tiles and adhesive. The EPA recommends testing before disturbing them.

Bathroom Remodel Debris: Planning Your Dumpster

What comes out of a bathroom

Tile: floor and wall tile, often set in thick mortar beds in older homes – the heaviest part of most bathroom demolitions.
Tub or shower: fiberglass and acrylic units are light but bulky; cast iron tubs are extremely heavy.
Toilet and sink: porcelain is heavy and breaks into sharp pieces.
Vanity and cabinets: mostly wood or particleboard.
Walls and ceiling: drywall, cement board or plaster and lath.
Fixtures: faucets, shower valves, lights, fans, mirrors and accessories.
Flooring underlayment: plywood, cement board or old mortar.

Because bathrooms concentrate heavy materials in a small space, the weight of the debris matters more than its volume.

What bathroom demolition costs

Item	Typical range	Source
Professional bathroom demolition	$300–$3,500 (about $8–$20 per sq ft)	Angi
Bathtub removal	about $100–$350	Angi
Dumpster rental, national average	$384 (most pay $294–$480)	Angi

A contractor’s demolition price often includes hauling the debris. If you do the demolition yourself, the dumpster is usually your biggest disposal cost.

Which dumpster size?

Small bathroom or half bath: a 10 yard container is usually enough, even with tile and a tub.
Full bathroom gut: 10 to 15 yards; weight is the limit, so ask about the included tons.
Two bathrooms, or a bathroom plus adjoining rooms: 15 to 20 yards.
Combined with a kitchen remodel: 20 to 30 yards. See kitchen remodel debris.

The cast iron tub problem

Older homes often have cast iron tubs that weigh several hundred pounds. Getting one out of a second-floor bathroom is a real job. Two common approaches:

Break it up: cover the tub with a heavy tarp or blanket and break it with a sledgehammer into pieces that can be carried. Wear eye and hearing protection, gloves and long sleeves – the shards are sharp.
Remove it whole: with several people, a dolly and a clear path, a cast iron tub can be carried out in one piece – and sold to a scrap metal recycler or salvage buyer.

Cast iron is valuable scrap. Many homeowners keep it out of the dumpster entirely, which also saves weight in the container.

Old materials: test first

If your home was built before 1978, painted surfaces may contain lead. Under the EPA’s Renovation, Repair and Painting Rule, contractors who disturb painted surfaces in pre-1978 homes must be certified and use lead-safe work practices. Old floor tiles, the adhesive under sheet flooring and some old wall materials can contain asbestos; the EPA recommends testing suspect material before it is disturbed. Asbestos waste never goes into a regular dumpster. See What can’t you put in a dumpster?

Donate or recycle before demolition

Vanities, mirrors, light fixtures and faucets in good condition can often be donated to a reuse store such as a Habitat for Humanity ReStore. Metal – old pipes, a cast iron tub or radiator – can go to a scrap recycler. Porcelain toilets and sinks are recycled in some areas into aggregate; ask locally.

Planning the work

Turn off water and power to the bathroom before demolition.
Protect the path from the bathroom to the container: floor protection, corner guards and plastic sheeting to keep dust contained.
Remove fixtures first: toilet, sink, vanity, mirror, accessories.
Tub or shower next, then wall tile and backer, then the floor.
Bag small debris such as tile shards and mortar in heavy contractor bags or buckets – easier to carry and safer to handle.
Load heavy material evenly across the floor of the container.

Keeping the house usable

If this is your only bathroom, plan the timeline carefully and consider a temporary solution – some homeowners rent a portable toilet for the construction period. See How many porta potties do I need? Keep the demolition phase as short as possible by having the container on site when work starts.

Common mistakes

Ordering by volume instead of weight: a half-full container of tile and mortar can already be over the weight allowance.
Throwing the cast iron tub in the dumpster: it adds hundreds of pounds that you could have sold as scrap.
Skipping dust control: bathroom demolition makes fine dust that spreads through the whole house.
Not checking for asbestos in older flooring and adhesive before tearing it up.
Damaging the drain: cover the open drain and toilet flange so debris doesn’t fall into the plumbing.

Tub-to-shower conversions

Replacing a tub with a walk-in shower is one of the most popular bathroom projects. It produces the tub (heavy if cast iron, bulky if fiberglass), the surrounding tile and backer board, part of the floor, and sometimes framing if the wall or plumbing moves. Plan for the tub separately – scrap or break it up – and size the container for the tile and backer board. A 10 yard container usually covers a conversion in a standard 5-foot alcove.

Safety during demolition

Wear eye protection, gloves, long sleeves and a dust mask or respirator; tile and porcelain shards are sharp, and mortar dust is fine.
Shut off water at the fixture or main valve and cap supply lines before removing fixtures.
Turn off the circuit for the bathroom before removing lights, fans or outlets.
Plug the drain and toilet flange with rags to keep debris and sewer gas out.
Carry heavy buckets of tile debris in manageable loads, not overfilled.

A typical timeline

Day 1: fixtures, vanity and toilet out; tub or shower removal starts.
Days 2–3: wall tile, backer board and drywall; floor tile and underlayment.
Following days: plumbing and electrical rough-in, new backer board, waterproofing – little debris.
Finishes: tile offcuts, packaging from the new vanity, toilet and fixtures.

Most of the heavy debris comes out in the first two or three days. If space is tight, a small container for demolition and a second small haul for packaging at the end can work better than one container for the whole project.

Budget checklist

Container rental, including the weight allowance for tile and mortar.
Possible overage per ton if the tile bed is thick.
Extra days if fixtures or tile arrive late.
Scrap value of a cast iron tub, which can offset part of the cost.
A portable toilet if the house has only one bathroom and the project runs for weeks.
