TL;DR
A standard 5 foot cast iron bathtub weighs 250 to 400 pounds, and a clawfoot or larger soaking tub can exceed 500, which puts it beyond what two people should carry down a staircase. Removal costs more than a typical single item, and more again upstairs. The material is good ferrous scrap, so it should never go to a landfill.
There are only two ways out: intact, with enough people and a clear path, or in pieces. Deciding which before the plumber disconnects it saves hours.
How Heavy Is a Cast Iron Tub?
Weight by type, for planning:
| Tub type | Typical weight |
|---|---|
| Standard 5 foot alcove, cast iron | 250 to 350 pounds |
| 5.5 to 6 foot cast iron | 320 to 450 pounds |
| Clawfoot, freestanding | 250 to 500 pounds |
| Cast iron soaking or oversize | 400 to 600 pounds |
| Steel enameled tub, for comparison | 60 to 120 pounds |
| Acrylic or fiberglass tub | 50 to 90 pounds |
Two quick tests tell you what you have. Tap the side: cast iron gives a dull thud, steel rings, acrylic sounds hollow and plastic. Or press the floor of the tub. Cast iron and steel do not flex at all, acrylic gives slightly.
Weight per person matters more than total weight. A 350 pound tub carried by two people is 175 pounds each on a stairway, with awkward hand positions and a load that cannot be set down midway. Three or four people is the realistic minimum for a whole-tub carry, and even then a stair descent is risky.
Break in Place or Carry It Out?
Breaking in place is the standard approach for cast iron on any upper floor or through a tight path. Drape the tub with a heavy moving blanket to contain fragments, wear a face shield, hearing protection, gloves, and long sleeves, and strike the floor and sides through the blanket. Cast iron is brittle and cracks into large chunks rather than shattering. Pieces come out in buckets at 30 to 80 pounds each, and enamel shards cut through work gloves, so handle chunks by the iron side.
Carrying it out whole makes sense on a ground floor with a straight path to a door, or when the tub is worth saving. Slide it on a moving blanket or plywood runner rather than lifting repeatedly, and remove the door casing if clearance is tight.
Never break a tub over occupied space without knowing what the floor can take, and never break one still connected to plumbing.
Antique Clawfoot Tubs Are a Different Question
A clawfoot tub with intact original feet and a reglazable interior has genuine resale value, sometimes several hundred dollars, and salvage dealers actively buy them.
What determines value: original matching feet, no cracks in the iron, an intact rolled rim, and a finish that is either sound or refinishable rather than chipped down to raw iron. Faucet drillings in the right configuration help.
If you have one, list it before demolition and let the buyer arrange the pickup. That is the only outcome where a 400 pound object leaves the building without costing you anything.
Standard alcove tubs from the mid twentieth century onward have no resale market. They are scrap.
Cast Iron Is Excellent Scrap
Cast iron grades as heavy melt or cast scrap at metal yards. It is not high-value like copper, but it is dense enough that a single tub is a meaningful amount of weight in a scrap load.
The enamel does not disqualify it. Yards handle enameled cast iron routinely, and it is the same material as old sinks and radiators.
For a homeowner with one tub, the credit is small and the trip is awkward, so the practical question is whether your hauler routes metal to a yard rather than a landfill. Most do, because their own disposal cost drops. Our comparison of junk removal versus a scrap metal yard covers when a self-haul is worth it, and where to take scrap metal explains what to expect at the scale. How yards grade material generally is in our guide to scrap metal value in junk removal.

Current Market Reality
Stairs are the single biggest cost driver on a tub, followed by doorway width and the number of turns between the bathroom and the truck. Quotes assume the tub is disconnected from plumbing, so a job where the crew has to wait on a plumber runs long. If tile surround comes out with the tub, the load shifts toward weight pricing and the tonnage jumps, which is covered in our guide to bathroom demolition debris. Disposal itself is modest because the iron has scrap value rather than a landfill fee.
How the common situations compare, from lower to higher cost:
| Scope | Relative cost (lower to higher) |
|---|---|
| Ground floor, tub already disconnected | Lower |
| Ground floor, full removal and haul | Moderate |
| Second floor, break in place and haul | Higher |
| Clawfoot moved out intact | Moderate |
| Stair carry surcharge | Lowest |
| Tub plus surround and tile debris | Highest |

Prep That Actually Lowers the Bill
Disconnect the plumbing first, or have a plumber do it: drain and overflow removed, supply capped, trap pulled or plugged so the room does not smell.
Cut the caulk and remove any tile or surround overlapping the tub flange. A tub with tile lapping over its edge cannot come out without breaking the tile anyway, so do it deliberately. Then protect the path, since hardboard over finished floors and blankets on casings cost nothing and prevent the damage that turns a cheap removal into an expensive repair.
FAQ
How much does a cast iron bathtub weigh?
A standard 5 foot alcove cast iron tub weighs 250 to 350 pounds. Larger and soaking models run 400 to 600. Clawfoot tubs vary widely between 250 and 500 pounds depending on size and wall thickness.
Can you break a cast iron tub with a sledgehammer?
Yes, and it is standard practice for upper-floor removals. Cover the tub with a heavy moving blanket to contain fragments, wear a face shield, hearing protection, gloves, and long sleeves, and strike through the blanket. Cast iron cracks into large chunks rather than shattering.
Is a cast iron tub worth money as scrap?
Modestly. Cast iron grades as heavy melt scrap, which pays far less per pound than copper or brass, but a single tub is 250 to 400 pounds so the weight adds up. Antique clawfoot tubs are worth far more sold intact than scrapped.
Do I need a plumber before tub removal?
Usually yes. The drain, overflow, and water supply need to be properly disconnected and capped, and in many places that work should be done by a licensed plumber. Junk removal crews quote on the assumption that the tub is already disconnected.
How do I get a tub down a staircase?
Preferably you do not. Breaking the tub in place and carrying out chunks is safer, faster, and cheaper than a stair carry with a 350 pound object. If the tub must come out intact, plan on four people, a stair-capable dolly, and full protection on walls and treads.
Getting It Hauled Away
Decide early whether the tub is leaving whole or in pieces, get the plumbing disconnected before crew time starts, and protect the path out. Our junk removal service can take it from there.
