As with any metal, the methods of cutting cast iron are divided into thermal and mechanical. The choice of a specific tool depends on the features of the design. Below is the equipment that saws (or cuts) cast iron:

  • pipe cutter;
  • angle grinder;
  • chisel;
  • Metal hacksaw;
  • jigsaw
  • plasma unit;
  • gas cutters.

Now it is worth evaluating cutting with the named tools with cast iron objects.

Preparing for disassembly

Cast iron baths are usually recumbent or semi-recumbent. They range in size from 85160 to 110210 cm. This is a large item, which is quite difficult to carry through the door.

There is another peculiarity. the great weight of the. Dismantle the bathtub by yourself and take it out of the apartment by yourself is impossible. You can not throw a cast-iron product on the trash either: objects of such dimensions are not taken out or removed by the utilities. As a result, the dismantling of a cast iron bathtub is accompanied by a rather peculiar preparatory steps.

From the bathroom remove all objects that can refuse on the way out. The washer and dryer will need to be moved if they can’t be repositioned. Need to remove shelves, cabinets, and even a cabinet under the sink. You may have to remove the sink and, in a shared bathroom, the toilet.

Remove the door from its hinges. The doorway is usually sufficient to remove the product, but it is very easy to scratch the sash. If the door is not removed, it is protected with film or a soft cloth.

The bathtub should be removed to the site for disposal, to the point of metal reception or dumping. You can’t usually do this with a passenger car. You need to contact services that offer bulky garbage removal services. Often these companies help remove the product, and the cost of this service does not change.

A cast-iron tub can be sawed off. Smash with a sledgehammer is not recommended: fragments can fly it a long distance, which is fraught with injury and damage to the finish. The product is sawed with an angle grinder with a disk on metal to 230 mm. Wear a respirator and protective clothing to do the work. Cutting takes a long time: the tool must be periodically turned off and the disc cooled. Before the final cut, you need to provide support for the parts of the bathtub. Large pieces when breaking will damage the tile.

Pieces of the tub are easy to carry and can even be loaded into a passenger car. It is still forbidden to leave them on the trash pad near the house.

Tools and materials

To remove a cast iron bathtub from the bathroom, you will need the following:

  • Peorator;
  • angle grinder with a metal disc;
  • wrench;
  • sledgehammer;
  • chisel, hammer, chisel;
  • Protective gloves, goggles, and a respirator.

The work is dirty and dusty, so you should not try to protect furniture. It is best to remove everything you don’t need.

Disconnecting from the sewer and water mains

Before working, turn off the water supply, then pour out the remainder from the faucet and proceed to disconnect. First disconnect the plumbing. Usually it is enough to unscrew the flexible hoses. If the faucet will be reused, the hoses are left in place. Disassemble the mixer in the usual way: remove the decorative plugs, unscrew the fastening nuts and remove the device.

Disconnect the siphon, if it is cast iron. It is likely to be corroded and “stuck” under the influence of moisture. Before dismantling, you need to treat it with a solvent. WD-40, and leave it for 1 hour. Then use a wrench to unscrew the nut and remove the cast iron trap. If the nut does not yield and after treatment, siphon sawed angle grinder.

You can use the following method: in the chisel chuck insert a chisel, switch the device in the “blow without drilling” and, resting against the end of the nut, press the trigger. The impact is strong enough to displace the nut, after which it is quite easy to unscrew. Diameter of the nut is large, so instead of a wrench may need a gas wrench.

By removing the siphon

Dismantling begins with removing the plumbing fixtures. In older homes, the elements of the drainage system are made of cast iron. Under the influence of high humidity components over time stuck to each other, covered with a layer of rust. In this case, use chemicals that corrode the corroded metal, such as universal lubricant WD-40.

  • Apply the chemical composition to the joints of parts, leave for an hour to work on the surface. Using an adjustable wrench, unscrew the nut, disconnecting the siphon.
  • If it is impossible to unscrew the washer, saw down a part of the sewer line with an angle grinder. The latter can be replaced by the chisel or wrench. Switch the tool into impact mode. Place the chisel on the end of the nut, turn on the torch. This breaks the connection and parts come away from each other, so you can dismantle the siphon. Repeat the action until the nut is unscrewed with a wrench.

Unscrew the flanges

In old houses, tiles were laid close to the bathtub rim, additionally forming a border of tiles. In this case you can free the bathtub by removing a part of the panelling. This will require a chisel and a torque wrench. Set the tool into impact mode and run it around the perimeter of the piece. If there is no peoratora use a hammer with a chisel, but manual processing will require more time.

Uncovering the sides of the bathtub.

If the bathtub is installed, you need to unscrew or cut its legs from the wall. Protect the floor with wooden boards or plywood, and then push down the sides. The bathtub will fail and fall on the boards.

If you can not free the edge in this way, knock down part of the wall, which rests on the plumbing. It remains to pull out the bathtub, turn it on its side and carry it out of the room.

Do I have to cut the legs?

The legs of the bath can be used for transportation. If they are embedded deep in the floor, they are sawn off with an angle grinder at the base. Using a metal disk, first the rear elements are cut, then the front ones. If you perform the work in the reverse order, there is a possibility of plumbing equipment falling on a person and getting injured. Before lifting the bathtub, you need to check the reliability of fixing the elements.

What are the peculiarities of the method?

According to reviews, we can conclude that the procedure of breaking the tub with a sledgehammer. this is the most practically proven method of dismantling. Nevertheless, it requires considerable physical effort. Not everyone can break a bath into several parts. The work must be performed by a physically fit person. Besides, the procedure itself should be performed during the day. Otherwise you will inevitably scandal with the neighbors.

A simple, efficient and economical way to seal large joints. But after sealing the joint with the assembly foam you will have to fight for aesthetics, closing the joint with decorative elements (see “The simple, effective and economical” section). below). When buying the foam, make sure it is moisture resistant.

Sequence of actions


Once the product has found its most vulnerable point, the following steps have to be taken:

  • The first step is to move the tub away from the wall. To perform this task will need a chisel and hammer, with which the sanitary product gets rid of the cement mortar around the perimeter. The optimal distance between the bathtub and the wall is 100 to 150 mm.
  • Using an angle grinder equipped with a cutting wheel, several cuts should be made on the tub. The task of the master is to deprive the product of its strength. The places of cutting on the bathtub should be its bent edges on both sides. They are used as stiffeners. If the work is done correctly, then from strong blows on the bottom of the cast iron product it will fold.
  • Break through the drainage hole. At this stage, you do not need to turn the tub. The master only makes very strong blows with a sledgehammer on the drain from the inside of the tub. Judging by the reviews, already after these actions, the bathtub is divided into two separate halves. If this does not happen, then we will have to deal with its sides.
  • Turn the bathtub on its side and cover it with old rags. A burlap sack is also a good idea. Apply the blows on the outer part of the cast iron object. As a result, the bathtub drain that has already been breached earlier should be even more enlarged. After a few strokes in the bathtub along its entire bottom a long strip is formed.

What are the options?

There are a total of 2 main ways to do the work:

  • dismantling with preservation of the integrity:
  • only the body itself (when it is not important to keep the coating)
  • the enamel of the bathtub (when the bathtub is planned to be used further for its intended purpose, e.g. after restoration)
  • Destruction.

The first option is simpler in terms of carrying out the dismantling itself, but causes a lot of problems when taking the product out. Such a basin weighs on average about 100 kilograms.

This method is worth using if you do decide to restore the coating or do something with your own hands from the hull itself.

You can breathe new life into an old cast iron bathtub. Artisans have come up with many options for its alternative use: flowerbeds, ponds, garden furniture and much more.

Disposal of splinters

Larger garbage cannot be thrown into containers. The owner must take care of the removal of the equipment to the dump by himself. A car for transporting the wreckage must be found in advance.

In large cities there are special services that offer customers the service of dismantling equipment and metal removal. Machines serving such orders are equipped with gas cutters, industrial grinders. This equipment allows cast iron items to be broken down efficiently, quickly, and easily.

Before you break down a cast-iron bathtub, it is worth thinking about whether it can still be useful in the household. Many gardeners use large old containers as rainwater tanks. If the tub is cut in half, or in several parts, from it you can construct a barbecue at the cottage, a bowl for flowers, a small greenhouse.
