Construction of a bathhouse from foam blocks: calculation of the amount of material and step-by-step instructions for construction

Making a bathhouse out of foam blocks is a sensible option for anyone trying to build a sturdy, well-insulated building. Because of their superior thermal insulation qualities and lightweight design, foam blocks present an affordable option for building small structures like bath houses.

It’s important to determine the required materials before beginning construction. This includes calculating how many foam blocks are needed based on the size of the bathhouse. You’ll also need to account for the materials for the doors, windows, roof, and foundation.

Building with foam blocks usually involves a simple procedure. Make sure the foundation is level and stable before starting to lay it. The foam blocks should then be stacked and tightly interlocked to create walls. At this point, windows and doors can be easily integrated, enabling customization.

As the walls take shape, think about adding concrete and steel rods for reinforcement. This will add strength. Installing the roof structure comes after the walls are up. Depending on your preferred style and local climate, this could entail prefabricated trusses or a less complicated roofing system.

The bathhouse can then be finished with finishing touches like exterior siding, electrical wiring, and interior insulation. Paying close attention to detail during the building process guarantees a well-built, effective structure that will fulfill its intended function for many years to come.

Is it worth building a steam room from foam concrete blocks??

In addition to being inexpensive, foam blocks are preferred because of the stone’s generally uniform structure. They come in various sizes, but you can expedite the construction process because of the material’s smooth surface.

There are several reasons why using foam concrete to construct a structure is a good idea:

• when a steam room and bath are part of a residential building on the site;
• when the construction region has mild winters;
• when you want to achieve high tightness;
• when beginners work or the masonry is done independently;
• if you plan to save money on construction.

Foam blocks are the best option for construction if the bathhouse is to be found on the first floor of a residential building because they don’t burn like wood does.

There are other circumstances in which it is not feasible to construct a bathhouse out of foam concrete. Penobsteton does not have enough resistance to frost, so this will not matter when building a structure there.

What types of blocks are suitable?

Although block baths are a relatively new concept, skilled builders have already written reviews detailing the best blocks to use when building a structure. Penoboton blocks vary in size and density; the material’s strength is determined by these properties. Blocks will be less dense the more air that was used to produce the foam during the manufacturing process.

D600–D800 density FEAL PEOPETONE blocks are used for bath construction. Because of their excellent strength and thermal insulation indicators, these blocks are ideal for building a sauna. They will turn into the best raw material when the structure’s supporting walls are built.

It is evident from the specifications for bath materials that the constituents need to be dependable, resistant to internal heat effects, and moisture-resistant. Foam concrete needs to be treated with a water-repellent agent during the construction phase before finishing because it can absorb moisture.

The D900–D1200 brand of blocks won’t matter in this case because they need more superior thermal insulation. Due to its excessive strength, grade D1300-D1600—which is utilized in multi-story construction—will become obsolete. The most common stone dimensions are 600 x 200 x 300 mm.

How to make a project and calculate how much material is needed?

The first step is to create and approve a bathhouse design, even before construction begins.

The following details must be considered when designing:

• presence of holes for ventilation;
• chimney from the steam room;
• diagram of engineering communications;
• presence of a heating source;
• availability of a heat supply source.

When designing, special consideration should be given to the installation of electrical wiring.

Additionally consider:

• location of the bathhouse;
• ground water level;
• water supply;
• thermal insulation;
• vapor barrier.

Errors in the calculations should not be present in the project; otherwise, construction will be problematic. Once the project is prepared, you can figure out how much foam concrete will be needed for building.

Because 600x200x300 mm blocks are frequently used, the length of the load-bearing walls must be determined. Then, using the indicators, determine how many blocks are needed.

For instance, two layers of foam concrete are laid edgewise for external load-bearing walls, but only one row of stone is required for partitions. Stones with dimensions of 600 x 300 x 100 mm can be used to construct walls within the bathroom.

Consumables and tools

In order to construct a foam concrete bathhouse, you must first prepare the necessary number of blocks. Since there is a chance of rejection during the work, it is best to approach the material with caution.

Additional materials required as well:

• cement, river sand and water – for laying on a cement-sand mortar;
• dry glue in bags – for laying on an adhesive composition;
• reinforcement bars;
• wire for reinforcement;
• sewer pipes;
• fasteners: nails and screws;
• metal corners;
• windows and doors;
• Decoration Materials;
• materials for thermal insulation and waterproofing;
• antiseptic;
• wiring and lighting fixtures.

The equipment you’ll need to get ready is:

1. drill with mixer attachment;
2. buckets for mortar and glue dilution;
3. Master OK,
4. wide spatula with teeth;
5. rubber mallet;
6. hammer;
7. perforator;
8. roulette;
9. building level.

Step-by-step instructions for DIY construction

To ensure proper construction, it is worthwhile to adhere to the technology step-by-step:

1. Foundation. It is recommended to use a strip foundation to reduce the load on the foam blocks. Formwork is made using boards, and for beacons I use nylon cord. A protective waterproofing layer must be installed at the foundation. Roofing material or a layer of bitumen mastic is well suited for this.
2. Walling. For construction, blocks with strength D600-D800 are used, the first 2 rows are laid on a cement-sand mortar, then an adhesive composition can be used. Experts say that the first 2 rows need to be reinforced, but some builders talk about reinforcing every 4-5 rows of bathhouse masonry. Openings for windows and doors also need reinforcement. A metal mesh with small cells is suitable for this. The foundation is reinforced with rods.
3. Masonry. Blocks are laid only on edge, while the vertical level is checked with a plumb line.

The joining seam’s thickness shouldn’t be more than 5 mm. An excessively thick seam will aid in the development of cold bridges.

Is insulation required??

Because of the properties of the building material used, the bathhouse needs to be insulated. Foam concrete is further finished and covered with a layer of thermal insulation because it absorbs water easily. This is simple to accomplish because the masonry turns out smooth.

Water repellents are applied to the walls beforehand, resulting in the creation of a thin layer of protection.

The materials used to make thermal insulation are:

• mineral wool,
• glass wool,
• jute felt,
• expanded clay or foam plastic.

Materials made of foil are occasionally used. Both the inside and the outside are insulated. First, a metal profile that is fixed to the wall is used to build the frame. There, insulation sheets are inserted and fixed. The last finishing is next.

To ensure a seamless building process, building a bathhouse out of foam blocks requires careful planning and accurate calculations. This article offers a thorough how-to, including a list of all the precise materials required and sequential building instructions. Every stage of the construction process, from setting the foundation to putting up the walls and covering the roof, is broken down into easily understood steps, even for individuals who are not experienced with building projects. Whether you’re thinking of creating a backyard getaway or a private sauna, this guide will provide you with all the information you need to finish your foam block bathhouse project successfully.

Difficulties and errors during the construction process

The majority Saving money is a common mistake that people make when building a bathhouse. As a result, they buy inferior materials that may break down while being used. Additionally, antiseptic impregnations and water repellents are not used in the construction of bathhouses. These substances have the ability to shield the building from moisture and stop the growth of mold and fungus.

Many contractors use material that is too thick or lay it in a way that deviates from the technology, which is an infringement on SNiP standards. All of these errors have hazardous repercussions: the bathhouse may collapse, posing a risk to one’s health and finances due to the necessary repairs.

Pros and cons

Foam block bath houses come with a number of advantages.

• the material has good thermal insulation, so saunas made of foam blocks are comparable in warmth to wooden ones;
• compared to other building materials, foam blocks reduce construction time;
• foam concrete is light in weight and does not exert excessive pressure on the foundation;
• a bathhouse made of this material will cost less than one made of the same brick;
• even an inexperienced person can build a bathhouse.

Foam concrete saunas have certain drawbacks, such as their vulnerability to moisture, the potential for condensation to build up, and the possibility of mold growth. Protection against these drawbacks is achieved through the application of antiseptic impregnations.

Owner reviews

27-year-old Andrey from Saratov

Since my family has benefited from my foam-block bathhouse for the past five years, I couldn’t be happier with my construction. Such a bathhouse has no cold bridges and is always warm inside. Given that I completed the masonry myself and obtained priceless experience, I am happy with the work completed.

Zhanna, aged 49, from Murmansk

Winters in our area are bitterly cold and frequently very humid. We didn’t consider all the details before deciding to construct a bathhouse out of a foam block. Consequently, the steam room’s walls are wet and will require new lining due to the fungus growing inside of them.

Igor, g. Permian, aged 35

As soon as I started building, I read up on all the characteristics of a bathhouse made of foam concrete. I instantly agreed with the workers regarding the use of impregnations because I knew that this material was prone to absorbing moisture. After three years of use, there is no buildup of mold or condensation in the sauna.

Matvey, forty-two. The Krasnodar

Our area enjoys pleasant warm weather with moderate winters. I made the decision to have a home sauna while the house was being built. I created a bathroom out of the same foam blocks that I used to build the house addition. The outcome is a cozy and dependable design.
