If the bath is designed with rooms on the second floor or if the building has an attic, steps will be needed to equip it. Given the specifics of this room, choosing stairs for a bath is not always easy.
Features of staircase structures for a bath
When equipping a bath, you should take into account the following aspects ladder construction:
- Dimensions;
- Tilt angle;
- Material resistance to high humidity;
- Safety;
- The stylistic direction of the room.
First and essential condition is the compactness of the steps. However, this should not interfere with compliance with safety regulations. According to the regulations, the minimum width of the march should be 1 m, and the width of the feet should be at least 20 cm. As for the angle of inclination, an angle of 45º is considered optimal.
Stair configurations may vary. A simple and reliable solution is a straight single-flight ladder. There are more intricate options: a turning march with winder steps or a design with an intermediate platform. However, it is not recommended to install a spiral staircase in the bath, despite its originality and compactness.
To save space, goose step stairs are suitable. Due different widths tread it becomes more compact.
It is important that the steps meet the style requirements of the building and are not knocked out of general style. Flight of stairs from wood it is better to install in a bath in traditional style or made in the spirit of minimalism. As for metal structures, they will fit into high-tech or techno styles. For non-traditional Turkish baths harmonious solution there will be stone steps.
Materials for flights of stairs
What material is the staircase in the bath made of? We must not forget about high level humidity in this room. If we are talking about a wooden structure, you should pay attention to rocks that are resistant to decay. Among them are larch, ash, wenge.
If the hosts stopped at metal steps, stainless steel is best. It is not subject to corrosion and deformation, therefore it can be used in a damp room. Owners Turkish bath you will need a solid stone staircase. Materials include granite and fake diamond. When choosing the latter, it is recommended to combine it with a concrete base.
Additional ladder structures
If there are shelves and an attic, additional structures may be needed. This applies to mini ladders for high shelves. If there is such a structure made of wood, it must be well processed so that there are no notches on the crossbars. At the same time, it should not be slippery to avoid injury. If the bath has an attic, you can install a folding or retractable ladder.

Modern suburban or country houses rarely build one-story, mostly two-story, three-story or one-story with attic floor buildings. In this case, there is always a need to somehow make high-quality movement between floors possible. good decision there will be the manufacture of wooden stairs that could provide a comfortable entry and carrying of heavy furniture or equipment. Let's just say that this is not an easy task. And if it is possible to order at least a project or even finished staircase elements from the manufacturer, then it is better to do so. Well, if you are confident in your abilities, have carpentry skills and free time, you can try to make a ladder yourself. Within the framework of this article, we will briefly talk about what design stairs are, how to perform the calculation and how to make a staircase.

Construction of a wooden staircase
It is necessary to choose the design of the stairs based on the space that can be used, the convenience of location, configuration and lifting, as well as for aesthetic reasons.
Conditionally everything wooden stairs can be divided into screw and marching.
Spiral stairs are used quite rarely. Mostly in extremely tight spaces. The second reason may be the desire of the owner - for aesthetic reasons. It is worth noting that the spiral staircases are not very functional. For example, it is extremely difficult to bring heavy furniture along it. In other words, it can serve only for the descent - the ascent of one person. For its manufacture, complex calculations will be required, since it will rely on one pillar - a support. The slightest mistake in the calculation of strength can lead to sad consequences.
Marching stairs- the most common. They consist of their marches, they are also called "flight of stairs", i.e. directly the steps and platforms that separate the marches. Marches can be either one or several. And there may be no platforms at all if the stairs are single-flight.
Marching stairs may have different design You can see them in detail in the diagram below.
There are direct marching stairs. At the same time, they can be single-march and two-march, separated by a platform for ease of movement. Such stairs can be located against the wall or not lean against the wall at all. characteristic feature straight stairs is that they take up a lot of space.
Most often, to save space and ease of use between floors inside the house, two-flight turning stairs are made. The rotation can be right angle (90°) or any other angle up to 180°.
March may have curvilinear design with a convenient angle for entering the stairs. In this case, all steps can also be rotary.
Also, two-flight and three-flight stairs may not have platforms, but only turning steps.
In order to choose the right staircase design for a particular situation, it is necessary to measure the free space that can be used under the stairs, make small calculations and draw a drawing. The drawing should show how the staircase is located, whether its elements interfere and how comfortable it will be.
Elements of wooden stairs
The above photo shows the elements that make up the stairs, and their names are indicated.
Kosour represents load-bearing beam, which supports the treads and risers from below. It bears all the loads.
bowstring also performs a support-bearing function. At the same time, there are recesses in it, into which the steps are inserted with the butt. This design used on one side if the ladder is adjacent to the wall, and on both sides - if the march is sandwiched between two walls. The bowstring is less preferable than the kosour due to the fact that it is not able to withstand heavy loads. Therefore, even if the stairs adjoin the wall, they still try to complete it on the stringers.
steps for stairs - wooden beams, consist of a tread (horizontal) and a riser (vertical). We step on the surface of the tread with our feet. And the riser is a vertical beam under the step, which encloses the tread space and performs a supporting function. It is possible to make stairs without a riser, in which case the step space will be free, the leg will not rest, but the structure will be less durable and reliable.
Steps can be rectangular, radius for a beautiful entry to the stairs, swivel at a certain angle to replace the dividing platform and running - the first step of a non-standard shape.
railing for stairs - wooden balusters and handrails. Their shape and size may vary. Basically, railings are made to order, in the form that the customer wishes.
If the staircase is more than one-flight, its design includes support post or pillars at the turning points of the stairs.
Before proceeding with the manufacture of stairs, it is imperative to make calculations and complete a drawing. Wooden drawings for stairs are made both independently and with the help of special architectural programs. In the latter, you can also perform calculations. A good solution would be to contact companies specializing in wooden stairs. So you can be sure of the quality and accuracy of the calculations.
Calculation of a wooden staircase
Number of steps and riser height
To determine the height of the stairs, we measure the distance from the base of the finished floor of the first floor to the finished floor of the second floor. If the finishing floor is not yet equipped, then its dimensions must be laid on the basis of "by eye". Because the wooden staircase becomes only on the final floor. IN this case we assume that the height from floor to ceiling is 250 cm, the thickness interfloor overlap together with the floor - 35 cm. Total 285 cm.
We make a calculation, starting from the height of the riser. The fact is that most often this size is standard and ranges from 15.2 to 19.7 cm. It is believed that this height is the most optimal for ease of use. Smaller - will knock down the step. Large - too heavy to climb and difficult to descend. From this interval we take the average value (you can take any) - 17 cm.
Number of steps = ladder height / riser height;
Since the number of steps cannot be uneven, we round to big side — 17 pieces.
In doing so, we have two options. We can first running step make it small, and the rest with a riser of 17 cm. Or we can recalculate and get a more accurate, but uneven result.
To do this, we divide the height of the stairs by the number of steps: 285/17 \u003d 16.76 cm.
So we can complete 17 identical steps with riser height 16.7 cm.
It is believed that the minimum tread width for convenience should be 22 cm, and the maximum 37 - 40 cm. If less, it will be difficult to descend, if more, the step will go astray.
For a more accurate calculation, there is a dependence:
- 2a + b = 64 cm;
- a + b = 47 cm;
a is the height of the riser;
b is the width of the tread.
Let's try the second formula: 47 cm - 16.7 cm = 30.3 cm. This width is quite acceptable, we can round it up to 30 cm.
For the sake of interest, we calculate according to the second formula: 2a + 16.7 = 64; a = 23.65 cm. This width is too small, so we will use the data obtained from the previous formula.
The width of the march of the wooden stairs
In principle, the width of the march is not strictly regulated in any way, but the number of marches will depend on the place that can be used for the stairs.
It is believed that the minimum comfortable width of the march is 80 cm. If the stairs are narrower, there will be difficulties with the passage fat people or carrying furniture. Options from 100 to 140 cm will be successful.
In order for the whole structure of the stairs to look organic, you can use the following hint: the width of the march should be a multiple of the width of the tread. In our case, these are 60 cm, 90 cm, 120 cm and 160 cm.
Ladder length
To calculate the length of the stairs, we need only two values that we have already calculated, this is the width of the tread and the number of steps.
Stair length = tread width * number of steps(without the last one - this will be the floor of the second floor);
30 * 16 = 480 cm.
4 meters and 80 cm- a rather large length, which "eats" a lot of space.
Therefore, if it is not possible to equip such a staircase in one flight and straight, you will have to change the design and make it two-flight with a turn of 180 °. In this case, you can make a dividing platform, or you can make turning steps. It is most convenient to make such calculations in special programs, where the location of the elements of the stairs will also be clearly visible.
Clearance height above steps
An important parameter. The beginning of the flight of stairs almost always falls under the ceiling, thus reducing the free space above the head of the person walking up the stairs.
Even at the stage of creating a drawing, it is necessary to calculate the height from the highest step, located under the ceiling, to the ceiling. The minimum allowable value that can provide a comfortable entry to the stairs, even the most tall people, is 195 - 200 cm.
Stringer length
Calculated using the Pythagorean theorem.
Ladder length2 + ladder height2 = kosour length2;
4802+2852= stringer length2;
230400 + 81225 = stringer length2;
Stringer length = 558,23 cm. We take with a margin of 560 or 580 cm.
How to make a wooden staircase
by the most simple solution will order from the company a project and ready-made elements of the stairs, with all the necessary cutouts. All elements will be numbered. After the unassembled stairs are delivered to the construction site, wooden stairs are assembled according to the attached drawing and diagram. So you do not have to buy a special tool for trimming and dusting around the house.
We buy material for a wooden staircase
If you decide to do self-assembly wooden stairs, start by buying building materials.
For bowstrings or stringers, a beam of 50 * 250 mm is required. Its minimum width can be 150 mm, if the design of the stairs allows.
For risers, we purchase beams with a minimum thickness of 25 mm, you can take thicker ones.
For beam treads, it is better to take from 30 to 40 mm. And you can the same as for the risers.
We order handrails and balusters from the manufacturer or buy ready-made ones, since in order to make them yourself and beautifully, you need to have considerable experience, knowledge and skills.
Install stringers or bowstrings
We cut the beam, which we bought for the stringers, from above and below so that we get the required length of the stairs. Then from below we cut off another thickness of one tread, i.e. 5 cm
Important! The fact is that when we did the calculation of the number of treads, we did not take into account the thickness of the steps. It is really not important for the whole structure, except for the first step - its height does not increase by the thickness of the tread.
We cut off the excess. It is better to use a jigsaw or a saw. But for lack of it, you can use a hand saw.
Then we attach the kosour to the place where the ladder will stand. Its upper edge should rest against the ceiling, and the lower one should rest firmly against the floor of the first floor. We check the horizontalness of the cuts for the steps.
Important! We need two such stringers, but depending on the loads that the staircase must withstand, there may be more stringers. In this case, we cut out all the others, using the first one as a template.
Thoroughly sand all surfaces. If necessary, we mill the outer edges, making roundings (for beauty).
At the bottom and at the top of the stringers must be connected to each other by a beam. To do this, cut them a quarter from the bottom and top. We fix to a thick beam with anchor bolts. If it is possible to fix the stringers to the walls, then we also use anchors.
If we use one bowstring, then it must be cut to the required length. Then cut out holes inside with a cutter - recesses for steps. The bowstring is fixed to the wall with anchors.
Important! Checking correct location bowstrings and kosour on the other hand, they should be located on the same level so that the steps do not have a slope.
Install steps and risers
After the stringers are tightly fixed, we begin to put the risers.
To do this, we cut the beam into required amount risers of a certain length. We level them relative to each other and sand them.
We fix it to the kosour with self-tapping screws on the front side. Then we putty them or hide them under decorative elements. You can also use special glue.
When all the risers are installed, proceed to the steps - treads.
To do this, we also saw the beam into the number of steps minus one. Then we skin their surface and mill the protruding outer edge with an angle.
Then we put them on top of the risers and fix them with self-tapping screws or screws.
Important! If we use the bowstring on one side, then we insert the step into the groove cut out in the bowstring, having previously glued the edge of the step and the hole in the bowstring.
We install the balusters on the steps and fix them with studs 100 mm long and 8 mm thick.
From above we install and fix the railing with self-tapping screws.
At this point, the work is completed, only the painting of the wooden stairs remains. For best preserved wood, while preserving its natural beauty, you can use special transparent varnish coatings.
In this article, we examined the manufacture of a single-flight straight wooden staircase with our own hands. If the project involves a staircase of a different design, then the installation will be different. For example, for a two-flight staircase, the platform and the supporting column are first installed and fixed, and then the stringers, risers and steps are already installed. Some steps in this case may not be straight, but rotary and rounded.
You need to think about the location of the stairs even at the construction stage. Changing the finished interior is much more difficult to implement, and the price of this service is much higher than the usual installation of a flight of stairs.
The staircase in the bath connects not only the steam room with the dressing room, but can serve as an exit to the porch or to the attic. If the house and the bath are located very close, then it is quite possible to tie them together. The stairs leading from the bathhouse to the second and first floors will allow you and your guests to quickly move from one room to another.
There are many options to save space. The spiral staircase in the bath will not take up much space, and at the same time will give interior decoration beauty and some uniqueness.

Buildings with several floors must be equipped with stairs. They make it easy to move between floors. The most important criterion when choosing a ladder is its safety. There are three main types of stairs. They can be made from metal, wood or stone. Stairs to the second floor can be spiral, mid-flight or combined. The appearance of the stairs also has great importance, since the staircase can become the main piece of furniture, or it can harmoniously complement it.
In every house or apartment with high walls and ceilings, there should be a temporary staircase that will allow you to carry out the necessary repairs under the ceiling or window at any convenient time. For such cases, a step ladder is suitable. Stair options are presented in a wide variety.
The universal transforming ladder can be double-sided, attached, ladder with a working platform and U-shaped.
Specially designed connections will allow you to change the shape of the stairs. They allow you to transform the staircase in a way that is convenient for the master, since the connections can be installed in any order. The automatic latching of the sections ensures easy and safe assembly.
Features of the transformer ladder:
- Can be used in industrial and residential areas.
- Ladders can be installed on surfaces with different levels, which allows you to perform difficult tasks. For example, they can be placed on marches, as well as on spans between stairs.
- The aluminum ladder is thin, has no big weight which makes it transportable. It takes up little space and is easy to transport. For its storage, an opening, balcony, pantry or trunk is suitable. Also, the ladder can be stored in the garage.
- The 3x12 stepladder provides reliability and ease of use.
- It has a tilting hatch and a third tier, which makes the work more convenient.
The ladder can be used for various specific jobs, which allows it to be used for repair work at home, at the cottage or in industrial premises. Any closed area sooner or later needs repair or restoration. When buying a ladder, it is important to pay attention to the OKPD code. Buy different kinds stepladders can be found in the Ikea chain of stores.
Criteria for choosing stairs to the house on the second floor
Multi-storey building needs stairs. It is not only a connecting element between floors, but also allows you to give the interior a certain charm and attractiveness. Today, designers offer samples of safe design stairs that allow you to realize specific ideas.
It is important that the stairs meet the requirements of GOST and SNiP, since safety and ergonomics must be considered first.
The size of the staircase structure will depend on how many square meters per room. There are three main types of stairs: spiral, mid-flight and prefabricated or combined. Selection criteria will vary depending on the type of room, the functionality of the stairs, as well as material costs. The latter depend on the ability to buy a premium or economy class staircase.
Selection criteria for stairs:
- The location of the stairs. The most popular places for mounting stairs are the center of the room and the area in the corner.
- Construction location. As well as the number of meters allocated for it.
- Design safety. It is important to take into account the presence of small children and the elderly, as well as people with disabilities in the house.
- Wall thickness. This will depend on how the elements are attached.
- Style in the interior. The materials and design of the stairs can complement the interior or become its center.
The draft diagram will allow you to imagine the location of the stairs and its combination with inner space. It is important to evaluate the advantages and disadvantages of the design before installing it directly. It is important to remember that, first of all, it must be safe.
Staircase to the second floor
Modern homes need not only safe, but also beautiful stairs that will give a home cozy atmosphere. Interroom stairs allow you to combine several spaces, while creating one, completely new. The dimensions of the stairs will depend on the type of room and its size.
The stairs to the second floor can be placed in the apartment, country house and even in garden house. But the types and sizes of stairs will differ significantly.
by the most popular species stairs are marching and screw structures. Marchers win in terms of popularity and safety of use. In turn, mid-flight stairs have subspecies.
Varieties of mid-flight stairs:
- On kosoura. They are safe to use. Manufacturers present a large selection of concise designs, sizes and decor options. Ladders can have risers, or they can be mounted without them. There are straight, broken and screw stringers.
- On bowstrings. Have a sophisticated appearance. Steps in this type of stairs are attached directly to the support beam from the inside. The design will harmoniously look in the hall, made in a classic style.
- On the Bolts. Often structures are made of metal. They are strong and durable. At the same time, they have a beautiful appearance and concisely fit into the interior. The ladder is easy to mount to the wall, ceiling and floor.
A room in which suspended stair structures are installed looks very unusual and easy. And here folding ladder perfect for a room leading to the attic. The choice of the type of stairs and its style as a whole depends on the type and purpose of the room.
Wooden staircase for the house to the second floor
Home improvement in several floors can not do without the installation of stairs. IN log house usually install wooden stairs, characterized by simplicity of design. IN wooden house With small area ladder structures are usually installed along the wall.
Before placing the stairs, it is important to draw sketches of its future location, and also to ensure that the door and other interior items do not interfere with a convenient approach and movement up the stairs.
If the manufacture of stairs is done independently, it is important to pay attention to the choice of material. It must be of high quality, durable, hard rock wood. Before assembling the structure, it is important to process each of its elements with a special material that will protect the tree from damage. external sources exposure: moisture, air, temperature change and insects.
Benefits of a wooden staircase:
- Durability;
- Reliability;
- conciseness;
- Simplicity.
Design of a multi-storey log house will not do without the installation of stairs. The design can be made independently, or you can buy ready-made. Before buying, it is important to decide on the type of stairs: mid-flight or spiral. For clarity, you can study the photos of the stairs different kind in the interior.
Spiral staircase in the apartment to the second floor
The production of staircases today surprises with a variety of materials, designs and prices. The selection parameters depend primarily on the purpose of the stairs and placement in a room with a certain area. Spiral staircases are light, airy structures that will add elegance to the interior.
The screw lift design is distinguished by its compactness, which saves a maximum of free space.
Spiral staircases can be round, triangular, square and even octagonal in shape. The device of the stairs poses a certain danger, so it is necessary to climb it with great care. But original design allows you to make the interior unique. These stairs look great in a bay window.
Materials for spiral staircases:
- Tree. One of the most common materials. It is durable, reliable and inspires confidence. Suitable for many interior styles.
- Metal. Provides wide opportunities for design. It goes well with wood and fits into any interior.
- Stone. The design is heavy, which makes it easier to mount. Natural stone they are used only for decoration, but the main structure is cast from concrete.
Stairs made of glass are gaining more and more popularity. In the interior, they look incredibly airy. When installing and operating them, it is important to take precautions, since the stairs are quite traumatic.
The best stairs to the second floor
It is very important that the stairs are comfortable. Of course, the main criterion for choosing a ladder is its safety. The safest are marching stairs. But this limits the choice of designs and impoverishes the interior.
Combined designs that combine elements of mid-flight and spiral staircases are very popular.
Modular stacked stairs allow you to create a unique, original and maximum safe staircase design. Rising up modular staircase gives the impression of weightlessness and extraordinary lightness. Examples of their “introduction” into interiors different style can be viewed on the internet.
Features of modular structures:
- Variability;
- Reliability;
- Ease of installation;
- Profitability.
Modular ladder - optimal design for installation in rooms with a small area. It is important to follow the rules for installing stairs. It should have a slope in the prescribed number of degrees. Type-setting structures such as LS 1200 and others can be purchased at building supermarkets and online.
Safe stairs to the second floor in the bath
Bath - a room with a fairly limited space. In the bath, every meter is important, so it is extremely important to pay attention to how much space the stairs take up. It is optimal to place in it such a ladder that does not take up much space and at the same time will be safe.
Universal wooden structure will ensure the safety of movement and allow you to choose convenient option designs: with straight or curved marches.
The location is important to determine even before the construction of the bath. It is important that the ladder is not located in the opening. In the bath, you need such a staircase that will allow you to move freely through the floors as much as possible.
Important selection criteria:
- Safety;
- Reliability;
- Space saving.
You should also take care of the external steps to the bath. It is better to install them under a canopy. It can be a brick staircase or paving stones. All types of stairs should be comfortable and safe.
Closed staircase to the second floor
stairs closed type considered safer. It is especially good to install them in a residential apartment with children and the elderly. The location of the stairs depends on the type of dwelling and the area of \u200b\u200bthe room.
Open stairs, unlike closed ones, do not imply the presence of risers.
Closed stairs are very often installed in the central part of the room, as they have a beautiful appearance. When installing a ladder, it is important to correctly determine the level of its inclination. If there is not enough space in the room, then it is advisable to place the stairs in the corner.
Benefits of a closed design:
- Safety;
- Reliability;
- Variability;
- Compactness;
- Conciseness.
Looks interesting combined design which has a 180 degree turn. It is reliable and at the same time saves space. Building a house is serious business. Especially if it is a house with several floors, which requires a responsible approach to the choice of stairs.
Staircase to the second floor (video)
Build multi-storey building- enough difficult task with an independent approach. It requires verified calculations, purchases quality materials and responsible performance construction works. If we are building a house with two and big amount floors, you should choose the type of stairs in advance and consider its location and installation method. A multi-storey building requires a safe connection of floors, which can be provided by stairs of mid-flight, spiral and combined types.
The staircase in the bath is a compromise between convenience, aesthetics and safety requirements.
Usually wood is used
Design features
At the input and internal model General characteristics. According to the material, wood is a priority, since more often baths are made from it. Solid beams, glued or rounded timber are used. From the breeds choose those that tolerate changes in the microclimate and are resistant to decay: birch, oak or larch. conifers short-lived and emit resin.
As for the varieties of structures, mid-flight stairs, both straight and rotary, are mainly used here.
Space is saved by leaving open steps.
Ladder options:
- entrance upstairs from the street (for the summer period);
- from an annex;
- indoors (used all year round).
Types of stairs in the bath
It is important to ensure that the steps do not clutter up the space, and the rise ensures safety.
Entrance to the bath
Let's take a look at each type of structure. To equip the porch, the foundation is first built after the building has undergone basic shrinkage. Several types of piles are driven in:
- For deep laying. They are installed below the level of soil freezing to maintain the position of the porch during the period of seasonal fluctuations. There are bored and screw.
- For shallow . Columns (steers) are used, which are deepened below the fertile layer by 40–50 cm. To avoid deformation of the structure, the site is attached to the building with the help of beams and crossbars.
The porch to the bathhouse should be equipped after the basic shrinkage of the building
If the access to the second floor is planned from the outside, the same requirements apply for it. The parameters fit into the GOST standards: treads - within 25-30 cm, and risers - 15-20 cm.
The steps are attached to bowstrings or stacked on stringers. Consider a fence. It is desirable to mount the beams holding the platform into the wall.
Rise to the second floor
To equip the stairs in the bathhouse, you will need a thorough study of the available area and the selection of use cases.
Traditional mid-flight structures are placed aside, closer to the corners, building an L-shaped or U-shaped staircase. Thanks to this configuration, it is possible to reduce the affected area.
Mounting process:
- Installed support beams at the beginning of the ascent to the second floor and on the turning part.
- Steps to the wall and supports are attached to stringers or straight bowstrings. In the first case, it is recommended to cut out the ridges, and in the second, notches for treads.
- Installation depends on the selected design model. Additionally, they make closed risers.
- Wooden handrails are attached to the outer part of the march. Use of other materials is not recommended due to heat.
Installation of stairs in the bath
If there is a catastrophic lack of space for construction, a compact goose step design is used.
Here it is possible to increase the slope while maintaining safety and convenience due to the treads alternating in width. Such models are often used for utility rooms, attics and mansards.
