The sauna smells sour what to do. How to get rid of humidity in a bath, remove an unpleasant odor. Choosing the type of sewer system

Modern Russian baths are far from the same hut on chicken legs with one room inside. On the contrary, it has now become fashionable to equip a whole bath complex- with a guest room, shower room and even a swimming pool. And the bathroom has long become something commonplace for the bath. And more comfort - the sewage system in the bath should be more perfect, and this time the hole under the foundation will no longer work.

Construction of a drainage well for water drainage

If the bath is designed for two or three people, and it is rarely used, then you can not spend money on an expensive system and not do something super complicated - it will be enough to equip a primitive water withdrawal from the bath and its going into the ground. For this, a drainage well is made not far from the bath - the depth that is necessary for a certain degree of freezing of the earth: for example, if this value is 70 cm, then the hole should turn out to be at least 1.5 meters. So, the order of work:

  • Step 1. At the bottom, 10 cm of clay is placed, and the bath is placed around the foundation and a trench for water drainage.
  • Step 2. Along the trench, the clay needs to be well leveled and given the appearance of a gutter with a slight slope towards the drain.
  • Step 3. Next, expanded clay, crushed stone or a mixture of gravel and sand are poured over the clay pad - a layer of about half a meter. This is drainage.
  • Step 4. The earth is poured over all this and compacted tightly.
  • Step 5. The drain pipe is insulated so as not to freeze in winter.

Such a sewage system in a bath with your own hands is not bad, it is only important to remember that periodically gravel and sand will become clogged and will need to be cleaned.

By the way, if the soil is sandy, such a well can be replaced with a so-called horizontal drainage cushion. This is a trench a meter deep, the same length and 30 cm wide. A 20 cm layer of rubble is placed on its bottom, and covered with earth on top. It is on this pillow that drain water... But if close groundwater, then it is necessary to take into account some points. More details here:

Here is another fairly simple method for constructing a drainage well for a bath: six old tires from a car are buried in the ground two meters from the steam room - on top of each other. And in the middle of the uppermost side, the drain pipe just enters.

The diameter of the well turns out to be what is needed, and the tires will not allow the pit to collapse. From above it all closes sheet metal and covered with earth. Video example:

If you need something more serious, then you can already think about a septic tank or a deep cleaning station:

How to make a sewage system on "capricious" soil?

So, if the soil near the bath does not allow water to pass through well, then it is better to equip a sewage system with a pit - to collect the runoff and then remove it. It is made of waterproof materials.

It is only important to make a water seal when arranging it - so that unpleasant odors do not get into the bath. To do this, the entrance of the drain pipe must be done at a height of 10-12 cm above the bottom, a plate is placed above the pipe, which is not fixed from below and a distance of 5-6 cm is left from the bottom of the pit to it.

As for sewer pipes, ordinary polyethylene pipes are quite suitable for a bath - they are durable and inexpensive. You can also cast iron. But steel will quickly become unusable due to corrosion. The minimum pipe diameter is 50 mm, but 100 mm is better, especially if it is planned to connect additional equipment.

If there is centralized system sewerage - excellent, it is always more profitable than the most thought-out sewerage for a bath with your own hands.

And, finally, no matter how long the sewerage system of the bath, there must be a well for its inspection and cleaning. It is called a viewing pit - it is a special pit with a concrete bottom and often brick walls. It is important to protect it with a double lid in winter - so that the water does not accidentally freeze: provide the inner one with heat-insulating material, and the outer one must be covered with earth.

What can cause an unpleasant odor?

Many bath attendants are also worried about how to make a sewage system for a bath without the slightest hint of smell? After all, it is precisely because of many that they refuse the elementary convenience in the steam room ...

Not nice smell where there is a sewage system, it is not uncommon. But it is not at all necessary for the steam room - and therefore it is possible and necessary to get rid of it. There may be several reasons at once:

  • Hydraulic shutter

It is also called a siphon - this is a specially bent pipe or other device that is filled with liquid and is designed to separate two adjacent gaseous media so that they do not mix. It is the hydraulic valve that is needed in order to bad smell did not get inside the bath. But he copes with his task only when nothing bothers him. And here's what can happen: the pressure in the system itself after the siphon will slightly exceed the atmospheric pressure - and from sewerage system air will go in the form of small bubbles or with a loud splash. And the air is unpleasant. Either the drains that move along the pipe will completely fill its cross section, then the siphon will empty under the influence of vacuum - thereby giving access to gases from the sewer to the bath.

How can this be prevented? Initially, the sewage system for the bath should be made of pipes of the maximum permissible diameter. The lower this indicator is, the higher the risk of overlapping by drains and the occurrence of this vacuum. Further, it is important to prevent deposits on the walls and blockages, which leads to blockage of the flow diameter of the sewer pipe.

  • Ventilation

In the bath, ventilation of the sewage system is mandatory - these are pipes that are combined with the sewer system and provide an air flow for constant pressure - so that household drains leave silently. But if there is no such ventilation or it is done incorrectly, during the discharge of wastewater from the bath, air will be rarefied and an unpleasant odor will appear.

Not difficult, right ?!

An unpleasant smell in the bath does not make anyone happy, this, without a doubt. What could be the reasons for a bad smell? Is it possible to get rid of the smell in the bath? Such questions often surface on the bathing forums. Consequently, no one can be insured against this misfortune.

First of all, I would like to remind everyone that there is no such problem that it would be impossible to cope with.

Any troubles in the bath can be solved. The only question is how much effort and material costs it will take.

To solve the problem bad smell all the same it will have to sooner or later.

Bad scent not only causes negative feelings and emotions, it can negatively affect health.

The sauna must smell good. Smell of the bath itself, brooms, stove heat.

People are so arranged, initially entering a room, we evaluate it by smell. And the memories of this place will primarily be about how it smells.

If you began to feel unpleasant odors, urgent action must be taken.

Initially, you need to sniff it properly and find out where the source is? Where the unpleasant smell comes from.

Smells like waste

Secret carbon monoxide in that it is colorless, light and odorless. How is it that it has no smell ?!

Yes, any owner of a bathhouse will say that he knows exactly how it smells like waste in a bathhouse. The catch here lies in the impurities of organic fuel elements.

We do not feel carbon monoxide itself, but the products of burning wood.

Whenever we heat the stove, carbon monoxide is emitted. This is the law of physics.

But feel carbon monoxide odor we start because the burning wood is not getting enough oxygen.

Why does the smell of fumes appear in the bath:

  • Poor oven draft.
  • Cracks in the oven masonry.
  • Chimney is blocked.
  • The ash was clogged with ash.

How to get rid of the smell of carbon monoxide in the bath

1. Inspect the oven carefully for cracks. If any are found, be sure to cover up and plaster.
2. Clean the chimney.
3. Go through the stones in the stove, get rid of stone chips and scrap.
4. Clean the ash pan and the mouth of the furnace itself.
5. Clean the walls and ceiling of the bath with a brush.
6. Ventilate the bath.

You can not wash in the bath until the waste is completely gone.

Harsh odors can penetrate and even be absorbed natural materials, of which there are plenty of them in the bath.

Metal oven

A commercially available metal stove can also give off unpleasant odors. There may be factory grease left inside the pipe.

  • The usual paint on your stove can be the cause of the unpleasant smell. When iron is heated, the coating of the stove can emit a wide variety of aromatic muck.
  • Unsuitable materials (stone wool or mineral wool) are used for sealing the flue connections.

How to get rid of the smell of a metal stove

1. To study the rules of operation and installation of the stove, maybe you did not take into account the smallest details.
2. Heat and ignite the oven several times.
3. Check the connection of structures; an asbestos cord should be used as a seal.

Stones in the oven

The most common cause of unpleasant fumes in the bath is stones. And here it is not only about the quality of the stones, but also about what they were watered with when they steamed.

Quality of stones

Maybe the stone itself smells bad? Maybe!

When heated to record temperatures and exposed to water, low-quality rocks break down and give off unpleasant odors.

This is because some rocks are interspersed with minerals and sulfur. Sulfur in the stone can be seen with the naked eye - gray, metallic and even silvery shiny blotches.

The high temperature and sharp cooling when supplying water to the heater with stones work wonders. Sulfur and minerals are released from their stone confinement.

The stone breaks down and gives off bad odors.

What do we rent for stones

A Russian bath is unthinkable without water supply to the heater. Often aroma oils, beer, kvass, broom infusions are added to the water.

  • Aromatic oils burn on the stones and a pleasant smell turns into a rich fumes. Oils leave stubborn deposits on the stones. Do not pour oil on the stove pure form... Replacing stones is much more expensive than any pleasant scent.
  • I know I want this Russian bread aroma, but there is so much in modern beer! Therefore, the long-awaited smell of bread does not last long. Gradually, it turns into an incomprehensible stench, which is firmly absorbed into the stones. For a long time in the bathhouse it smells disgustingly far from bread.
  • Leaves from a broom got into the stone backfill of the stove. The leaves are burning, the smell is appropriate.

How to get rid of stove odors

1. Go through and wash the stones.
2. Clean out the heart of the backfill.
3. Discard stones with cracks, colored stains.
4. Throw out burnt-out, empty stones.
5. Only fill the heater with certified products.
6. Do not use loose rocks in the oven.
7. When placing in the oven, take into account the safe temperature conditions every stone.

paints and varnishes

Russian bath never chased additional treatments and impregnation of shelves, walls, benches and so on.

It has happened since antiquity that the Russian bath does not tolerate synthetic materials, paints, lacquer finishes and polishes.

Sauna cabins are a completely different matter. They initially imply the use of modern technologies and synthetics.

Classic Russian steam bath does not accept anything like that for a very simple reason.

We rent water on stones, we steam ourselves with brooms.

Sudden changes in temperature, water (which repeatedly changes its state from liquid to vapor) can change the properties of even the best impregnation at the molecular level.

Moisture and heat penetrate any crevice and destroy any protection. As a result, we have a toxic smell in the bath.

How to get rid of the smell of varnish and impregnation

These are global works.

If the cladding is impregnated, you will have to change the entire lining. Painted benches, shelves - try sanding the boards. If it doesn't help, throw it away and order new ones.

There is simply no other way to get rid of the smell of varnish or paint. Continue to steam with such smells in the hope that they will evaporate is stupid.

It can be compared to a weekly course of toxic aromatherapy. A sane person would never agree to voluntarily breathe paint or varnish for an hour.

Smell from under the floor

Under the floor, it can smell of either stagnant sewage or rotting floorboards.

Why does sewage smell? The sewer drain is clogged, an error in the installation of the sewer.

How to get rid of smell from under the floor

1. Take it for granted: in case of smell from under the floor, no fragrances and special means disinfection will not help. It is required to open the floor, find out the cause of stagnant waters. Perhaps the sewage system is made without a water seal (this is also a siphon), you need to redo it.
2. Replace decayed or moldy boards.

How to maintain a good smell in the bath

The bathhouse itself is a place to get rid of dirt and sweat. All that our body has developed in a week.

You can't go straight to the steam room with a week of dirt on your body. The heated air reveals even faint odors quite strongly.

Perhaps the heavy spirit of an unwashed body is not a problem for you. But it spreads throughout the steam room. Literally everyone feels it.

Respect the bathing fraternity: rinse or shower before taking a steam bath.

The bath must be cleaned regularly. Clean the floor, wash basins, ladles, shelves and benches, dry washcloths, do not leave soggy soap.

Be sure to get rid of the brooms that have served their service.

Watch out for the first signs of mold and mildew. Deal with them immediately, preventing them from spreading.

On fine hot days, be sure to dry and ventilate the bath, opening all the doors wide open.

Pleasant odors without any negative consequences for the heater are guaranteed!

There is a recommendation to spray oils not on stones, but on walls. I do not recommend doing this. The fact is that the oil will be absorbed into the wood and leave its scent in it. But not all oils are combined with each other, allergic reactions are possible.

A well-planned bath project not only increases the operational life of the building, but also protects it from the appearance of mold and pathogenic fungi, and also increases heat transfer heating installation... The main requirement of the bath is a thorough discharge of waste water.

A properly designed structure using concrete and planks will eliminate odors and reduce the growth of pathogenic microorganisms.

How to make a do-it-yourself bath drain? You will find the answer to this question in our material.

How is the internal sewerage system arranged?

Correct outflow waste water in the bath can be done in several ways:

  • flowing;
  • not leaking.

In the first case, it is collected in a special section, where the waste liquid flows into sewer pipes... In the second version, during the construction of the building, a certain angle of inclination is made with additional gutters for draining dirty water.


A detailed diagram helps to avoid common mistakes when self-construction... It includes:

Trench preparation for pipe laying. The depth of the grooves should not exceed 0.5 m. correct angle tilt. To do this, each subsequent pipe is fixed 3 cm higher than the previous one.

The bottom of the trench is sprinkled with sand. The height of such a backing should be 16 cm after dense tamping. During installation, it is important to observe the angle of inclination.

Further, all pipes are connected to each other and laid on the bottom of the pits. If there will be a bathroom in the bath, then it is necessary to install an additional sewer riser... To do this, it is fixed at the wall surface with a special retainer.

For proper circulation of air masses in the toilet, it is necessary to install additional ventilation... This will reduce the retention of unpleasant odors indoors.

After that, proceed to laying the flooring. During the installation of the sewage system, it is necessary to attach additional metal gratings. They will prevent large debris from entering the drain hole.


To eliminate the unpleasant odor, special water locks will help. They are rubber pads that are fixed in the area of ​​the drain hole.

The main parameters for choosing a sewer system for a bath

How to drain in a bath? Before proceeding with the construction of an external sewage system, it is recommended to take into account several main factors:

  • the intensity of the use of the bath room;
  • dimensions of the building;
  • a kind of soil composition on the site where the room will be located;
  • the level of soil freezing in winter period time;
  • connection to the central sewerage system.

These factors are integral to the initial stages bath design. For frequent use of the premises, it is necessary to design complex system sewage drainage.

For this purpose, additional soil filtration is carried out. In addition, it is enough to use a waste pit here. Waste will gradually be absorbed into the soil cover.

If the site is dominated by sandy soil, then drainage rings are used for reliability. For clay soil, optimal solution will strengthen interior walls... As the pit fills with waste, it must be cleaned with special equipment.

Advantages and disadvantages of sewer drain devices

Today, there are a huge number of devices for arranging a drainage system for a bath. They have both positive and negative sides... These include:


Drainage well. It is a deep pit, the walls of which are filled with filtrate. To do this, use sand, fine gravel, pebbles.

The advantages of this method include: low cost of materials, ease in the process of arrangement. The disadvantages include the laborious process of replacing the filtered masses with new ones.

Drain well. it large capacity for collecting sewage fluid, in which waste from the bath gradually accumulates. As it is filled, it is cleaned using special equipment or a machine.

The advantages of such a system are: simplicity in the process of installation and arrangement drain pit, low cost. TO negative qualities include: frequent cleaning, inconvenient location of the drain well. As a rule, installation should be carried out at the lowest point of the site.

Pit. It is located under floor covering baths. Waste waste is collected in this pit and passed through self cleaning through filtrate from fines.

TO positive qualities systems include: low cost of materials, easy installation... The disadvantages of such a structure are: low carrying capacity, it can be used on sandy and sandy loam soils.

Ground filtration. This is a system that consists of a septic tank and several pipes. Purified water passes through them. The pipeline is laid at a certain angle, due to which all liquid will drain and be absorbed by the soil on its own.

The advantages of such a system are considered: it can be used for the entire sewer network, with its help, a thorough cleaning of the liquid from harmful impurities is carried out. The photo of the drain in the bath shows the process of filtration of sewage waste.

Owners of private households sometimes face an unpleasant situation when the bathhouse smells of sewage. Experienced plumbers will tell you what to do when such problems appear, and what methods of dealing are the most effective.

Chemical Compositions

If the causes of sewage odors lie in the accumulation of waste and the multiplication of bacteria inside the drainage system, then it is advisable to use special chemical compositions cleaning the drain parts and removing fat deposits from the pipe walls.

The best means to cope with such tasks are:

  • Mole.
  • San Clean.
  • Odorgon.
  • Domestos.
  • Chirton Clean Gutters.
  • Expel Bio.
  • Deboucher Active.
  • Mr. Muscle granules.

Household folk remedies

Time-tested and user-tested products are also able to eliminate sewer odors in the bath.

  • For this purpose, ordinary food salt is poured into the pipelines, which should be washed off after a quarter of an hour with an abundant amount of running water.
  • A solution made from 1 tbsp will be a quite worthy substitute for salt. l of caustic soda and 500 ml of boiling water. The resulting bubbling mixture is poured into the drain pipe.
  • Also, for cleaning, you can pour a small amount of baking soda into the pipe, then pour 9% table vinegar, plug the hole and open hot water after a quarter of an hour.

Elimination of breakdowns

In some cases, defects in the drainage system and a violation of the integrity of the sewage system become the cause of the appearance of an unpleasant odor in the room.

The problem can also be caused by improper joining of tubing elements. The presence of gurgling noise inside the structure indicates problems with the water seal or vacuum inside the riser.

You also need to make sure that the length and diameter of the pipes that drain the water and the level of their slope are correct. All identified defects should be eliminated as soon as possible.

Sewer bath systems, as a rule, include pits, shambos, and drainage wells and other elements that settle and purify water, so the failure of even one unit can cause unpleasant odors to appear in the room.

Unprofessional actions of installers during construction can lead to undesirable consequences. In this regard, the question often arises of how to eliminate the smell of sewage in the bath. To solve this problem, you need to find out why it has arisen.

Clearing the blockage

Most often, the smell is observed with the wrong choice of a hydraulic seal - a bent pipe filled with water and designed to separate neighboring gaseous media. The siphon prevents the appearance of an unpleasant odor in the bath, but only if nothing interferes with its work. Experts recommend choosing hydraulic valves with the largest diameter and avoiding blockages.

Ventilation creation

When building a bath, you need to take care of creating sewer ventilation. Together with hydraulic valve this system will ensure that there is no unpleasant odor in the building. Ventilation consists of pipes integrated with the sewage system and providing air flow. The result is constant pressure maintenance and silent wastewater disposal.

The absence or improper design of ventilation leads to the fact that when draining household waste, the air is rarefied and the appearance of odor. If you have a certain skill, ventilation can be done independently from a 50 mm pipe. It is brought out to the roof of the building and covered with a special cap.

Sealing pipes

Depressurization is an equally common cause of an unpleasant odor. To prevent this problem, you need at the joints plastic pipes use special rubber gaskets... You need to change or apply them silicone sealant when leaks are detected.

An unpleasant smell often arises in the bath, which does not allow you to steam and have a pleasant time. There are various reasons for its appearance, on which the sequence of actions depends. If you cannot solve the problem on your own, you should contact the professionals.
