Bath stoves with their own hands from a pipe

Description of typical chimney stove schemes

The chimney stove is a metal cylinder with holes for the firebox and ash drawer and a chimney welded to the top. There are two main variants of tube furnaces:

Horizontal models are suitable for baths and industrial premises, as their design provides for the installation of a tank for heating water and other auxiliary devices.

On lying stoves are installed barbecue grills and grates, which makes them the best option for the homestead or dacha.

Vertical stoves take up a small footprint and are suitable for heating huts and cooking in small country kitchens.

Synopsis. In a vertical stove, wood burns faster and gives more heat, while horizontal designs melt slower, but allow longer heat retention with less fuel consumed.

Preparation of tools and materials

The following tools will be needed when making a round iron stove from a large pipe:

  • welder;
  • angle grinder with various attachments;
  • electric impact drill;
  • various locksmith tools;
  • asbestos cord.

In addition, you will need these names of consumables:

  • metal pipe 500, 530, 600 or 700 millimeters across with a thickness of 8-16 millimeters and a length of up to one and a half meters
  • smoke and charcoal exhaust pipe of 120 to 150 millimeters in size;
  • Steel pipe for the compartment with stones, size. 300, 350, 400 or 420 millimeters;
  • sheet metal 600 by 800 millimeters;
  • hinges for hinging the doors;
  • 1/2 or 3/4 inch pipe used for water;
  • Ball valve with the same thread;
  • 500 mm metal rebar with a bar size of 12 to 18 millimeters;
  • 2 doors;
  • square metal profile legs;
  • cement;
  • bricks and sand.

You can even make a heater out of an unnecessary gas cylinder.

Do not buy for self-made pipe, used, because there is a risk that it will be from the oil industry.

Such a roll is not suitable for welding stove, as it has been treated with protective coatings that emit toxic substances when heated. In addition, these pipes have a high radiation background.

The chimney is an important part of the flue gas exhaustion.

  • Ceramic. The chimney made of ceramic has the longest shelf life. Maximum resistance to high temperatures.
  • Brick. Brick chimney because of the rough surface quickly accumulates soot and slows the draft.
  • Steel. Steel chimney is the most suitable for the baths because of the affordable price. Also because of the rapid heating of metal, put a tank, after use for procedures. Chimney made of stainless steel is the most relevant. This material is not afraid of water, high temperatures, little corrosion, lightweight, durable and cheap.
  • Before installing it is necessary to mark the place for the hole.
  • The chimney is fitted with a casing of galvanized steel, then rings are put on, which are fixed on the ceiling. The lower tube is fastened with self-tapping screws. Clamps securely fix the chimney.
  • The second part on the roof. Holes between the roof and the chimney are filled with expanded clay or asbestos.


Without a pre-made drawing, even with some knowledge to create a working unit is not always possible.

Here are the optimum solutions for furnace installation, both with remote and built-in furnace. Option with a built-in furnace chamber is not quite convenient because the heating of the bath takes place from inside the steam room, while with a remote element you can follow the fuel from the anteroom.

According to the drawings of the horizontal stove for the bath from the pipe with their own hands, you can see the difference in the design of both options:

Chimney for the stove in the bath will need to make, regardless of the type of fuel or size of the steam room. The principle of operation of any device is based on the ability of heated air to rise up. Exhaust gases, coming out of the furnace exhaust channel, go to the chimney. They can be with a route inside the building and along the outer wall.

Each type has a number of advantages, but the most common way of laying pipes indoors. When passing through the floors and exit to the roof, it is recommended to equip such places with an additional layer of thermal and waterproofing. It is recommended to use thermal insulation sleeves, or to wrap the parts with mineral wool or other material.

The gases pass through the ducts and out into the atmosphere. The second job of the chimney is to provide reliable and sufficient draft for normal combustion. And if in the beginning, when firing up the firewood you can provide additional draught by opening the ash drawer and slide, then the ash drawer should be closed when burning the filling Ventilation of the furnace is the chimney concern.

Building the foundation for the furnace

The next stage in the manufacture of the furnace is the arrangement of a reliable base.

  • At the site where the furnace will be installed, dig a pit to a depth of 55 cm, length and width of 75 cm.
  • The bottom is filled in with small gravel up to 35 cm high, compacted.
  • Rubble cushion is poured with concrete mixture in the following proportions: 1 part cement, 5 parts sand and water. Allow the foundation to cure for 24 hours.
  • Lay a sheet of roofing felt on the ready foundation and use it as a waterproofing layer.
  • Pour the waterproofing with a concrete mix: 1 part cement. 3 parts sand, 5 parts gravel of a small fraction and water. The substrate is carefully smoothed and allowed to set until it is completely hardened.
  • On a concrete base is arranged platform of bricks 75 × 75 cm. Brickwork is done in single or double rows using a bonding mortar based on clay.
  • Shielding board is made to protect the sauna walls, near which the stove will be installed. Fireproof bricks are used for the screen, laid on the side edge. Shielding can have a height of 1.2 meters, and the installation of heating equipment is carried out at a distance of 25 cm from it.

As for the disadvantages, in this case they will be a direct continuation of the advantages of pipes:

bath, stoves, their, hands
  • It is difficult to work with thick metal.
  • tool consumables are needed (angle grinder and welder).

Drawings of bath stoves made of pipe

Furnace for the bath consists of several elements connected in series to each other by means of electric or gas welding:

  • From the case. It has an air vent with a lid, a portal under the cobblestones, a firebox, grates.
  • From a tank for heating water. Sometimes it is made not as a separate element, but as an extension of the body.
  • From the chimney.
  • From the spark arrestor on the chimney.

Water goes through the overflow pipes inside the tank and is taken out by means of sockets for cold and hot water supply.

Construction Diagrams of Stoves for Steam Bath, Description of Stove Layout

Before dealing with the issue of the device of stoves for the bath, we ourselves spent a lot of time studying this topic. So we know that people who have an idea about the construction of bath stoves, usually do not condescend to explain everything from the basics, and most of the texts on the Internet and even written by those who are not at all in the subject.

In this situation, we felt it important and necessary to share with you what we have learned. Let’s start with the theory, and then we’ll show you the typical schematics of bath stoves.
