Advantages and disadvantages of building a bathhouse from adobe

Constructing a bathhouse using adobe provides a unique combination of historical charm and useful features. For centuries, adobe (a blend of clay, sand, and occasionally straw or other fibers) has been utilized in construction because of its sustainable nature and inherent insulating qualities. When building, adobe construction can be a financially advantageous choice, particularly in areas with a lot of clay-rich soil and low material costs.

The thermal efficiency of adobe construction is one of its main benefits. Because adobe walls are thick and dense, heat is slowly released at night and absorbed during the day, helping to regulate indoor temperatures. Due to their inherent thermal mass, adobe bathhouses can use less energy and are better for the environment by requiring fewer additional heating and cooling systems.

Furthermore, adobe buildings frequently have a distinct aesthetic appeal; any setting is given a rustic charm by the earthy tones and textured surfaces. For those who want to blend their construction with the surrounding landscape or create a natural, eco-friendly retreat, this aesthetic feature may be especially appealing.

Despite its benefits, using Adobe for construction has drawbacks. Its vulnerability to moisture is one significant disadvantage. Even though adobe can survive dry climates well with proper care, it can deteriorate in continuously wet conditions if it isn’t protected or maintained properly. This means that unless additional waterproofing measures are put in place, adobe is less suitable for areas with high rainfall or humidity.

The lengthy process of building an adobe structure is another factor to take into account. In contrast to contemporary building materials that can be put together rapidly, building with adobe usually necessitates careful mixture preparation, hand-forming bricks or walls, and allowing enough time for drying and curing. When compared to traditional methods, this labor-intensive process can cause construction timelines to extend.

Advantages	Disadvantages
1. Cost-effective material using readily available earth.	1. Susceptible to water damage without proper sealing and maintenance.
2. Excellent thermal mass, keeping the interior cool in summer and warm in winter.	2. Requires skilled labor and knowledge to properly mix and lay adobe bricks.

Is it possible to build?

Without a doubt, experts state that it is possible to construct a sturdy and long-lasting bathhouse out of adobe; however, to do so, you must carefully adhere to the nuances of adobe construction technology, take into account all of the unique properties of this material, and balance out any drawbacks.

Although clay absorbs and releases excess moisture like wood, the bathhouse developer will need to take extra precautions to waterproof the walls and foundation due to the clay’s lack of resistance to water.

When selecting walls made of adobe blocks, developers should consider the following:

1. Climate of the area, in northern and humid areas. On the sea coast, such a bathhouse should not be built; over time, the adobe will soften and collapse.
2. Take into account the characteristics of the soil and the permissible type of foundation. Usually this is a strip foundation with a height of at least 0.5 m, waterproofed with roofing felt in several layers and the width exceeds the walls by at least 20 cm. This is necessary so that a thick protective layer of plaster or other finishing can be installed.
3. The seismicity of the area should be no higher than 8 points.
4. It is recommended to build one-story baths. In areas with high seismicity, walls are reinforced with antiseptically treated wooden frames with diagonal braces.
5. Mandatory interior and exterior decoration. Outside it can be plaster, inside – plaster + lining.
6. Installation of the heating furnace must be carried out with reliable fire protection.
7. Installation of an effective ventilation system is required to prevent the relative humidity in the room from increasing.
8. The roof should be low and wide to reliably protect the walls from rain.
9. The finish must be waterproof and vapor-permeable, with a layer of 5 to 10 mm. Cement finishing is not allowed.
10. It is mandatory to install jumpers with a waterproof board at least 5 cm above the technological openings of windows and doors.

It is not possible to construct adobe homes in areas that are susceptible to earthquakes, near the coast, with high humidity, on mild slopes, with a lot of groundwater, beneath trees, or in regions that frequently flood.

Only dry, sunny days are suitable for construction; rain or extremely humid air force closures the work, and polyethylene is placed over the erected walls.

Which adobe blocks are suitable??

Two types of wall materials are typically used in adobe construction: light wall materials, which are almost entirely made of clay, and heavy wall materials, which are strengthened and water-resistant by the addition of sand and straw.

Lightweight adobe is not appropriate for a bathhouse because clay takes a long time to dry—at least three months—because it is so afraid of water.

For a bathroom, heavyweight adobe is the recommended wall material because it is both energy- and environmentally-efficient. Furthermore, modern additives have improved its production characteristics even further in this era of advanced technologies:

• sand, expanded clay and crushed stone half with clay provide the drying blocks with protection from strong shrinkage and ensure the preservation of the required dimensions and precise geometric shapes;
• casein, bone glue and more modern material, such as liquid glass, are used instead of water, giving a strict geometric shape to the blocks, preventing them from spreading during the hardening period;
• lime removes moisture from the block into the environment, they increase the overall moisture resistance of adobe;
• fibrous cellulose and shavings, as well as straw, increase the elasticity of adobe and increase its resistance to temperature changes.

Citation. Although there is no standard size for Adobe blocks, 400x200x200 mm blocks are the most commonly used.

Additionally, the following production requirements must be met by adobe bricks:

• density in the range from 1500 to 1900 kg/m3, which is comparable to traditional red brick;
• thermal conductivity in the range from 0.1 to 0.4 W/mxC, which is two times lower than that of red brick, and, therefore, such walls of the bathhouse will be warmer and it will warm up faster;
• compressive strength in the range from 10 to 50 kg/cm2, corresponds to a similar indicator for wood concrete and foam concrete blocks;
• frost resistance not lower than F35, which corresponds to concrete blocks;
• moisture resistance is low, which must be taken into account from the initial stage of building a bathhouse made of adobe bricks;
• low production costs;
• high noise protection characteristics;
• environmental Safety.

Requirements

Conditions for walls that support weight:

1. Experts recommend installing adobe walls in a bathhouse made of a heavy block over 50 cm; for internal partitions, the permissible size is from 30 to 40 cm.
2. The masonry technology is similar to concrete blocks, only no more than 2 rows should be laid per day to ensure high-quality drying and adhesion of the blocks.
3. Masonry mortar for adobe consists of 1 part clay, 1 part sand and water.
4. Additional blocks can be obtained by processing adobe with an ax.
5. Adobe walls must be protected with an external and internal finishing layer with high water resistance and vapor permeability, the plaster layer must be from 5 to 10 mm, plastering with bricks is allowed.
6. For interior work, gypsum plaster is preferable, but cement plaster cannot be used on adobe walls due to its poor adhesion to clay.

Crucial! Technological apertures are redirected at least one meter away from wall corners and intersections, and lintels are supported on the walls by wood, brickwork, or concrete pads.

Requirements for additional adobe bath structures:

1. The best foundation for a adobe bath is a strip foundation, material: concrete, you can use brick, rubble, sand-concrete blocks. The foundation must be waterproofed with several layers of roofing felt.
2. Above the technological openings for windows and doors, wooden lintels with a thickness of at least 5 cm are installed, which undergo antiseptic and fire treatment, a waterproofing layer is laid under the board.
3. Wooden beams for roofing are also impregnated with waterproofing solutions and brought onto the walls at least 15 cm, a board is laid under the beam. In some cases, the beam is embedded in the wall, then their ends are wrapped with roofing felt.
4. The recommended angle for an adobe bath is about 40 degrees to reduce the spreading pressure of the roof on the walls. The roof overhang is large, from 70 to 80 cm, to throw the drains away from the walls.
5. Roofing material can be anything: slate, sheet and metal tiles.
6. The floor is insulated with expanded clay, a wooden flooring is made on the logs, waterproofed and then any covering with high water-protective characteristics is installed. In the washing room and in the boiler operating area, the floor is made of cement with tiled decoration.

Project

Drawing up a project that includes the facility’s sanitary and fire safety features is a necessary first step in the construction of an adobe bathhouse.

Kindly take note! Although you can use a ready-made project of a neighbor’s built bathhouse or download it from the Internet, it is preferable to order the project from a design organization.

It is crucial that an undertaking of this kind considers the characteristics of the adobe bathhouse:

1. Foundation – strip.
2. The number of rooms, at least three, should be: a steam room, a dressing room and a vestibule.
3. The area of ​​the steam room is at least 4 m2 per person in order to comfortably place benches and a stove in it.
4. Adobe absorbs moisture strongly, so you need to perform a high-quality finish. For adobe baths, the rule is that the thickness of the inner layer of finishing is 2 times thicker than the outer one.
5. Adobe walls are made multi-layered, with mandatory steam, moisture and heat protection.
6. The location of the heater must include a foundation.
7. The foundation for the stove is waterproofed with several layers of roofing material. Lay it separately from the main one with a minimum distance to the wall of 5 cm, cover the gap with sand.
8. The foundation for the furnace should be 50 mm larger around its perimeter.
9. Brick for laying the furnace – fireclay.
10. You can install metal stoves, but in this case a brick screen with channels for heat convection is provided.
11. For fire protection of walls, 25 mm plaster applied to a metal mesh is used.
12. Not only walls, but also floors and ceilings are subject to fire protection in the area where the furnace is operating. For this purpose, metal screens or other non-combustible materials can be installed.
13. The bathroom should have a convenient location so that it can be accessed from any room without disturbing visitors.
14. Ventilation should provide three times the volume of air circulation.
15. Electrical wiring must be made in a moisture-proof manner.
16. An adobe bathhouse must be equipped with central or autonomous water supply and sewerage systems.
17. Drainage drains must be installed in the washing room.

Materials and tools

Use a basic clay mortar with 10% cement added when laying adobe walls; in stressed areas, use masonry mesh.

Crucial! The batch should be measured so that it fills in 40 centimeters of the wall (2 rows), and then you should wait for the masonry to dry completely, which should take at least 7 days.

This is related to the advice to only construct an adobe bathhouse during the summer.

Masonry equipment: adobe blocks

• containers for mixing and carrying the solution: buckets, tanks and concrete mixer;
• shovel for mixing masonry mortar;
• level for controlling the vertical and horizontal walls, plumb lines;
• square, folding meter and tape measure;
• cord-mooring when laying versts between rows, ensuring horizontal and uniform seams;
• trowel and trowel;
• slab and pick;
• rule;
• mopping for the construction of furnaces;
• axe;
• Bulgarian.

Step-by-step instruction

Once the project has been chosen, the foundation is ready and adobe blocks are made.

The project states that they excavate the walls and perimeter of the bathhouse, typically to a depth of one meter. It is filled with broken bricks or rubble, each layer containing cement mortar. They start building adobe walls after the foundation has had time to settle.

Instructions for building an Adobe brick bathroom, step-by-step:

1. They begin laying walls with a thickness that is determined by the project and depends on the climatic region of construction.
2. It is allowed to complete 2 rows in one go, with bandaging, by analogy with laying cinder blocks, then wait a week for the masonry mortar to set.
3. As the walls are raised, boxes are installed in the technological holes for windows and doors, they are tied to the walls with wire and lined with adobe.
4. Leave openings for ventilation and removal of flue gases from the stove.
5. Beams and rafters are built into the upper level of the walls.
6. Wooden sheathing is placed on the rafters and the roofing pie is laid according to the project.
7. Perform internal waterproofing of the walls of the steam room and shower.
8. Finish with clapboard or tiles.
9. External thermal protection of the walls is carried out, on top of which a finishing layer of plaster is applied.
10. They construct a floor on the ground on beams with waterproofing, ensuring reliable flow of water into the sewer system.

Note: The floor is constructed prior to finishing, and the joints and seams between the blocks aren’t sealed until the walls are built.

Do-it-yourself insulation

Even in the coldest winter, the adobe bath is fairly warm. Its heat-resistant qualities are superior to those of brick and only marginally below those of wood.

However, thermal protection and vapor protection work together to ensure the long-term viability of the adobe bath. Furthermore, this kind of work can be placed inside the bathhouse as well as outside. This results from the necessity to protect adobe walls due to their high vapor permeability.

Mineral or basalt wool is the best insulation for adobe walls; it can be used for floor and ceiling thermal protection as well as inside and outside the walls.

Benefits of using mineral wool to insulate adobe bathtubs:

• convenient form: mats, slabs, rolls;
• high fire resistance, can withstand temperatures up to 1000 C;
• high noise and heat protection;
• can be laid on uneven surfaces;
• environmentally friendly material;
• inertness to most chemical and organic substances;
• easy installation, possibly done by hand;
• does not collapse when the house shrinks, can be installed immediately after laying adobe blocks;
• affordable price.

Crucial! When insulating baths made of adobe blocks, users blame mineral wool’s high moisture absorption for its drawbacks.

Mineral wool is prone to biological contamination, such as fungus, and needs to be waterproofed on both sides of the insulating layer. Consequently, more antiseptic treatment of the wall surfaces will be needed.

The external adobe baths thermal protection process for walls:

1. The walls are prepared, the old external adobe masonry is cleared of plaster, and the new one is primed to adhere the finishing material.
2. Level the surfaces of the walls.
3. The walls are treated with antiseptics and rodent repellents, after which they are thoroughly dried.
4. A layer of waterproofing is installed, a wooden sheathing is filled with bars, according to the size of the insulation boards, the joints are connected with an overlap of 100 mm and glued with tape.
5. The insulation is installed in the niche of the crate of the dispersal, it is impossible for the material to dangle or protrude from it.
6. Install another layer of vapor barrier membrane on top of the mineral wool.
7. Install horizontal guide battens to fix the membrane and slabs in the niches.
8. They perform finishing with siding, block house and use any other finishing option that can be installed on the sheathing.

The thermal insulation of an adobe bath should only be done in dry weather conditions with an ambient temperature between +5 and +20 °C. Failure to do so may result in partial shrinkage of the mineral wool and curvature of the lining. There is a 25 mm air space between the mineral wool and the film.

When there is insufficient or no external thermal insulation to maintain the necessary temperature conditions, internal insulation is applied to the walls, ceiling, and floor of an adobe bath.

Similar technology is used for insulating internal walls as it is for external walls.

Laying is accomplished with the required lathing device, ventilation gaps created by installing mineral wool, and waterproofing membranes on both sides.

Whether an underground is present or not determines whether floor insulation is installed.

Since the "fungi" in the first example are only needed to stop the mineral wool from moving horizontally, fewer of them are needed to correct the insulation, making it comparable to walls in terms of technology.

Without a basement, the floor is thermally protected layer by layer from the bottom to the top:

• level the ground;
• lay roll waterproofing with a layer of at least 5 cm;
• pour a layer of expanded clay at least 15 cm thick;
• logs are used as beacons; the board must be strong and not bend, otherwise its sharp vibrations can quickly destroy the insulation.

The technology used for further installation is comparable to wall thermal insulation.

Difficulties and errors

Despite the ease of manufacturing, the process of laying adobe bricks is sophisticated because of the material’s propensity to crumble when damp conditions are met.

Note: If the climate, topography, and soil of the area do not match, mistakes and challenges in installing samanble baths may arise during the selection of samanite wall material.

The primary errors that Adobe Bath developers make are:

• the foundation is chosen incorrectly;
• the foundation is thin and does not match the size of the adobe blocks;
• the foundation is poorly deepened;
• the foundation has not been waterproofed;
• simultaneous laying of more than 2 rows of blocks;
• there is no reinforcement of technological wall openings;
• hydro- and thermal protection of walls, ceilings and floors has not been completed;
• violations of sanitary and fire standards when installing bathhouse equipment;
• The overhang of the roof of the bathhouse does not protect the walls from precipitation.

Advantages and disadvantages

Like any wall material, Adobe has benefits and drawbacks that should be considered by the developer before choosing to use it for a bathhouse.

Benefits

• low construction cost, since blocks can be created and laid on your own from available materials – clay and straw;
• high material density up to 1900 kg/m3;
• low thermal conductivity from 0.1 to 0.4 W/μS, which ensures the safety of heat in the bath and a quick rise in temperature;
• sufficient compressive strength of dry blocks up to 50 kg/cm2;
• good frost resistance not lower than F35;
• environmental Safety;
• good noise protection parameters of adobe walls;
• high fire resistance of the material, such a bathhouse will not be able to burn, except wooden structures;
• the construction of an adobe bath does not require highly qualified builders, the process is accessible to performers who have basic skills in construction;
• construction does not require the use of heavy equipment, the blocks are not heavy, they can be made and transported in the local area.

There are several drawbacks to this material that should be considered when building; the primary ones are:

• low moisture resistance of the blocks, therefore they need to be reliably isolated from dampness, for example, the walls must be plastered and whitewashed with lime;
• The presence in the blocks of straw as a filler increases the likelihood of damage to the walls with insects, rodents and fungus, in connection with which the surfaces should be processed with protective equipment;
• a large volume of straw in the working composition of adobe increases the fire hazard of the material;
• long period of construction, due to the fact that the masonry takes a long time to dry;
• construction can only be carried out in dry, warm weather;
• large shrinkage of walls, especially in cases of poor compaction of adobe;
• heavy adobe with a low percentage of fillers, requires wall insulation;
• high labor intensity of work due to manual production of adobe blocks;
• large wall thickness, more than 0.5 m, which reduces the usable area of ​​the bathhouse.

Reviews

In order to make an informed decision, the developer should consider the views of other potential customers before deciding to construct an adobe bathhouse.

The subject of adobe baths is discussed extensively on a number of forums, where actual owners of these establishments offer both positive and negative perspectives. Here are a few of them:

1. Soared in a saaned bath, inside no European -renovation – white clay, very hot and the spirit in it is excellent.
2. You can build an adobe bathhouse, the steam room needs to be sheathed with hydro-, vapor barrier and mineral wool with foil and lining, and then to your taste.
3. If waterproofing and ventilation are not created between the adobe and the lining, the lining will not protect the adobe, the bottom will be damp and rot.
4. I met an adobe bathhouse, which was built in the 30s of the 20th century, and is still in operation.
5. For the adobe bath, I adopted the following interior decoration: plaster of the ceiling and walls, vapor barrier, insulation, aluminum foil, lathing and lining.
6. You will get a normal bathhouse if you do everything correctly and wisely. Be sure to sheathe the inside with wood, and the outside is not bad either.
7. Saman is a good material. Only from below it is necessary to make high-quality waterproofing.
8. There was a sad experience when the adobe walls were plastered with cement, and after 2 years one wall crumbled right during washing due to a violation of the waterproofing.
9. With proper thermal insulation and condensate removal from the walls, adobe is a very competitive building material.
10. In the old days in Kuban, adobe baths were practically not lined with reed mats at most, the main thing in them was ventilation or vents.

Peruse evaluations regarding the building of an adobe bath on the Forumhouse and RusBani forums, as well as here and here.

Cost of work

The price of installing bathtubs made of adobe blocks varies by location; Moscow and the surrounding area have the highest cost. Furthermore, the cost of installation is determined by the size and complexity of the construction project.

Only during the warm season, when a general increase in production leads to relatively high prices in the construction services market, is work completed.

Citation. Although the cost of hiring a construction company will be at least 30–40% more than hiring independent contractors, the quality of work and warranty requirements will also be higher.

In 1.5 blocks, the average cost of masonry adobe baths with dimensions of 390x190x190 mm and a wall thickness of 0.59 m is:

• 1 m2 — 945 rub.;
• 1 m3 -1950 rub.;
• 1 block – 30 rub.

You must account for the walls’ dimensions and any technological openings in order to determine the total cost of masonry. As an illustration, consider a wall that is 10 m long, 3 m high, has a 2.8 m2 window opening, and a 10 mm seam:

• wall area will be – 27.2 m2;
• block volume – 13.2 m3;
• number of blocks – 935 pcs.

• area – 27.2 m2 x 945 = 25,704 rubles.;
• volume – 13.2 m3x 1950 = 25,740 rubles.;
• piece per block – 935 pcs. x 30 rub. = 28050 rub.

The advantages and disadvantages of constructing a bathhouse out of adobe should be carefully considered. Adobe, a blend of straw, sand, and clay, acts as an excellent insulator, keeping the interior warm in the winter and cool in the summer, all of which can lower energy expenses. Because it uses easily accessible natural materials, it is also environmentally friendly. But adobe buildings need to be carefully maintained, particularly in humid areas where moisture can eventually erode the walls. If they are not properly reinforced, they are also vulnerable to damage from earthquakes and heavy rains. When choosing whether or not to build a bathhouse out of adobe, consideration should be given to a number of factors, including climate, maintenance capacity, and environmental concerns.

Watch this fascinating video to learn about the benefits and drawbacks of an adobe bath.

Constructing a bathhouse using adobe has a number of clear benefits. To begin with, adobe is a naturally occurring and eco-friendly substance that is primarily composed of clay, sand, and straw. Because of its composition, it is easily accessible in many areas, which lowers the environmental impact and cost of transportation. Additionally, because adobe buildings have superior thermal mass qualities, they naturally regulate the climate by keeping warm in the winter and cool in the summer.

Adobe is also renowned for its longevity with proper upkeep. Adobe buildings are long-lasting provided they receive routine maintenance and are shielded from the elements. Compared to other building materials, its longevity not only guarantees a dependable structure but also lowers long-term maintenance expenses.

Additionally, using adobe in construction encourages regional craftsmanship and community involvement. Local artisans with generations-old knowledge are typically involved in adobe construction. This procedure saves cultural traditions and skills that might otherwise be lost, in addition to boosting the local economy.

Even with these benefits, there are a few noteworthy drawbacks to take into account when constructing an adobe bathhouse. Water damage susceptibility is a major concern. Since adobe is porous, it can deteriorate if it is exposed to too much moisture or a protracted downpour without sufficient protection. To reduce these risks, appropriate roof overhangs, drainage systems, and protective coatings are crucial.

The labor-intensive nature of adobe construction is another disadvantage. It can take a while to mix the materials, shape the blocks, and wait for them to dry before building. Furthermore, although adobe is widely available in certain regions, it might not be in others, necessitating careful consideration of local resources.

In summary, constructing a bathhouse out of adobe offers a unique combination of thermal efficiency, environmental sustainability, and cultural richness. To ensure its longevity and resilience, though, meticulous planning, upkeep, and consideration of local conditions are necessary. Homeowners can make well-informed decisions that are in line with their practical needs and environmental values by weighing these benefits and drawbacks.
