Ventilation grilles for doors - how to choose and install. Ventilation in the bathroom door and other methods of removing humid air from the room Ventilation rings the door to the bathroom

Fresh indoor air is a guarantee not only of people's health, but also of the safety of many finishing materials. In most rooms, the problem of oxygen inflow is solved simply - by ventilation. The bathroom has no windows, so it requires high-quality ventilation - both forced and natural.

To create the first, fans are used, and with the second, doors with ventilation can help. To improve an already installed solid door, wooden and metal door ventilation grilles, which can be easily installed with your own hands, will help. There are several options for door ventilation - which one is better to choose?

Materials for making doors

Before installing the first door that comes across in the bathroom, you need to understand whether it is suitable for organizing ventilation - whether it lets air through on its own, and, if not, whether a grill or ventilation rings can be mounted. Find out also about the optimal door sizes for your bathroom.

There are the following options for materials for the manufacture of bathroom doors:

Glass... Frosted glass doors are great for wet rooms - they are resistant to moisture and high temperatures, and they look good. They also easily withstand the large number of heating and cooling cycles that are typical for a bathtub that is constantly filled with hot steam. If ventilation holes are not pre-made in such a door, it will not allow air to pass through.
Plastic... The cheapest option, inferior to analogs in aesthetic characteristics. It withstands all aggressive influences as well as glass. If you have certain skills, you can equip such a door with a ventilation grill.
Solid wood... Poorly withstands moisture and temperature changes, but is best suited for organizing door ventilation.
Woodworking products- laminate, chipboard, MDF - after treatment with special impregnations, they withstand moisture well, and it is easiest to install ventilation in them. Like the plastic models, this option is quite cheap.

Thus, despite the worst resistance to moisture, wood options are better for organizing a constant air flow - then you can even cut the ventilation grilles for the bathroom door with your own hands.

Ventilation organization methods

According to the norms for the bathroom, natural ventilation is provided - for this there must be a gap in the floor. In practice, however, this gap is usually closed with sills or a sealant to avoid leaks during a flood. Therefore, bathroom doors with built-in ventilation have spread. There are two options for organizing it. You can also use a silent fan with a non-return valve - learn more about the benefits here.

Ventilation grates

This option is a window cut out at the bottom of the door, closed with a plastic, wooden or metal grill.

Ventilation rings and grilles in doors

From below, it is done because cool fresh air sinks to the floor due to convection.

Such grilles have a number of advantages:

variety of designs;
opacity;
curtains create an obstacle to the continuous flow of air - there will be no draft in the room... but oxygen will still continuously flow into the bathroom.

The grilles can have a variety of sizes, be installed in different quantities: one, across the entire width of the door, or several in a row - it all depends on the designer's imagination.

Ventilation grill in the door

When installing with your own hands, it is important to take into account such a moment: the overhead ventilation grill must necessarily stand level, at right angles to the floor.

Ventilation rings

The location of such ventilation holes is similar to the grilles - they are located at the bottom of the door, at a short distance from the floor. In fact, these are simple holes in the door.... inside which plastic or metal rings are inserted that perform two functions:

improve aesthetics;
protect the cut from moisture and temperature.

The design of such fixtures is simple and less varied than that of gratings, but there are options here too.

Air vents in the doors

So, you can find not simple rings, but closed with a protective or noise-absorbing mesh, which not only prevents you from looking inside the room, but also creates a barrier for insects.

How to choose ventilation for your bathroom door

The easiest way is to select a door that has been fitted with vents at the factory. There is a problem with this option: it can be difficult to find a model that fits the existing interior. But you can not think about the material and choose any door you like.

The second way is to make holes with your own hands. In this case, you will have to look in the direction of wooden models, since it is difficult to cut glass at home, moreover, you need a special tool for this.

Round vents in the door

Cutting plastic is simply dangerous - it is very easy to ruin such a door without the skills and experience of such work.

There is also a third option. If you can't find a ready-made door with ventilation for the bathroom, and you don't have the time and desire to tinker with work with your own hands, you can use the simplest way to organize the flow of fresh air. Namely - to grind the door from below, making a gap between it and the floor. With due care, this will not spoil its aesthetics in any way, ventilation will be no worse than with special holes in the array .

DIY ventilation

Having decided on the option for organizing ventilation, you can start working - making holes in wood or plastic will not take much time and effort, and only the most basic tool will be required for this.

You will need the following equipment and materials:

Ruler and pencil;
level;
drill, jigsaw or glass cutter;
grille or ventilation rings for the door;
mounting glue or self-tapping screws, depending on the ventilation model.

Installation is carried out in the following order:

Lattice or rings are measured if dimensions are not specified in their documentation.
Marking is applied to the door leaf. Of course, you can simply attach a grate or ring and trace with a pencil, but accuracy in this case may suffer. Please note that a couple of millimeters should be added to the ventilation size on each side.
Using the appropriate tool, holes are drilled or sawed in the blade.
Sections are carefully sanded with sandpaper and then varnished. This will further protect the material and improve the appearance of the door.
The rings are lubricated with glue and inserted into the holes; the grilles are screwed on with self-tapping screws on both sides. It is worth checking the evenness of the installation using a water level.

When working, it is imperative to observe safety measures - use gloves and goggles.

If you are not sure if you can do it right, it is better to entrust the work to a professional.

Thus, ventilation in the bathroom door is not a whim, but a necessity. Without it, the comfort from using the bathroom will be incomplete and even more - it will be simply dangerous. It makes no sense to avoid organizing a constant flow of fresh air into this room - it is very simple to choose the right option, and installing the grill or rings with your own hands takes no more than half an hour, even for a person without experience.

Ventilation grilles for doors to the bathroom, room, room

The lack of fresh air in the house can cause the residents to feel unwell, since carbon dioxide accumulates in a room that is not ventilated for a long time, and a sufficient amount of oxygen is required for a person's normal well-being. In addition, household chemicals and finishing materials release toxins into the air, which, accumulating, can also be harmful to health.

If we talk about ventilation in the bathroom, then the situation is even more serious. In the absence of air movement in a humid environment, molds are formed, the surfaces of walls, doors, furniture accumulate moisture and become unusable.

The problem of ventilation in bathrooms has become especially urgent in the past few years due to the appearance on the market of new noise, hydro and thermal insulation materials. Finishing with such materials makes the bathroom more comfortable and beautiful, but many of them do not let fresh air into the room. When installing a fan in a bathroom, effective ventilation of the room will occur only when the door is open, since a draft is needed for the fan to work well. According to the rules, there should be a small gap between the bottom of the door and the floor, but most people find this approach inconvenient and unaesthetic and install doors that close very tightly, leaving no gaps.

All these problems can be solved by a ventilation grill installed on the door. Today on sale you can find doors with an already built-in grille or with special ventilation holes-rings. But if the door is already installed and there is a problem with air circulation, then you just need to purchase and install the grill.

Types of ventilation grilles

Today, on the market for construction products, you can find many different variations of ventilation grilles. All these designs have differences in shape, purpose, design and color materials, sizes, prices.

The primary classification feature that determines the types of grilles is the method and place of their installation. On this basis, they are divided into:

For installation on the door, supply grilles are used. They are made from the following materials:

Ventilation grilles made of plastic have high corrosion resistance and reasonable price. But when direct sunlight hits them, the plastic loses its attractive appearance, and over time it can begin to deteriorate. Therefore, plastic grilles are best used for interior doors inside the house.

Aluminum gratings are quite durable, lightweight, not afraid of sunlight, but they are somewhat more expensive than plastic ones.

Wooden grilles are designed for indoor installation. Their advantages: environmental safety, external presentability, which allows them to harmoniously fit into the interior of the room. However, it should be borne in mind that natural wood requires special regular maintenance, in the absence of which the product may lose its appearance and deteriorate. The cost of wooden ventilation grilles is high in comparison with other analogues.

Steel gratings are heavy and expensive, but at the same time are considered the most durable and durable. Such structures are most often installed on front doors, since they are too heavy for interior doors.

When installing a grill on the front door, you must choose a model with a protective mosquito net so that mosquitoes and flies do not enter the house.

Ventilation grilles let in very little light and practically exclude the possibility of viewing; it is impossible to see the person behind the door through such a structure. In shape, these products can be round, square or rectangular, but the latter option is the most common.

Design features

The main part of the structure is equipped with V-shaped lamellas fixed on a frame made of plastic or metal, and the counterpart is already without lamellae. Despite the fact that this design is quite simple, such products effectively perform their function, maintaining an optimal microclimate in the rooms. Installation of the grill will prevent the appearance of mold, mildew and high humidity.

Rectangular door grilles

Bathroom door grill

Rectangular grilles are installed on kitchen doors, bathrooms and toilets. This allows the air flow to circulate properly inside the rooms. In addition, such products are also used for installation in window sills, so that warm air masses emanating from heating radiators are evenly distributed throughout the room.

These structures are made of high quality and durable plastic. Some models are equipped with insect screens or a movable airflow damper. Also, if desired, you can install a grill with a built-in fan - in this case, the ventilation effect will be the best. Today, there are various color and design options on sale, so for each door you can choose a grille that matches the color and style.

Round grates

Round grilles for doors

The design of round grilles is practically no different from rectangular ones. Such products are also equipped with a mosquito net, can have movable dampers or a built-in fan. The size of round structures, as a rule, does not exceed 15-20 cm in diameter, and for their installation, round holes are made in the door in size. Products up to 10 cm in diameter are installed at the bottom of the door several pieces in a row. Larger grilles can be placed on the sides of the bottom or top of the door. In the presence of moisture and mold inside furniture cabinets, such grilles are installed on the cabinet doors. In this case, glue and mounting ribs are used for installation.

If there is no proper air circulation in the office production room, as well as in a private bathroom, kitchen or bathroom, ventilation grilles must be installed on the door. You can do this yourself or ask for help from specialists who will perform the following steps:

The building code will determine the optimal size of the grille required for your door. The size depends on the internal dimensions of the room and its purpose.
They will make a hole in the door of the required size and install the grill.

For self-installation, you will need the following tools:

Ruler and pencil;
jigsaw;
screwdriver or glue.

Work order:

First, using a ruler, you need to take off the dimensions of the purchased grilles (as a rule, there are always two of them in the kit).
Next, on the door, you need to mark the places where the grilles will be located. In this case, the holes should be approximately 1-2 mm larger than the length and width.
Then, four round holes are made at the corners of the marking with a large drill.
Insert the jigsaw blade into one of the holes and carefully cut out a rectangle of the appropriate size along the markings. You need to cut carefully so that the material does not break off. Most room doors are filled with paper honeycomb inside. It should be borne in mind that the jigsaw is suitable for doors made of wood or wood processing materials. For other materials, appropriate tools are used.
Now attach the grates to the two sides of the hole made. If they enter too tightly, then enlarge the hole by sharpening with a file or a rasp.
If the instructions for use of the product indicate that the grille is attached with glue, then they will be attached using construction glue. Before glue is applied to the surface of the door, it must be treated with a cleaning agent to remove dirt and grease. Otherwise, the grill may come off after a while. Most models for doors are fixed with self-tapping screws.

Ventilation grilles not only restore the correct air circulation in the premises, but also perform a decorative function. These structures are quite attractive, giving the home a modern touch.

Ventilation grilles for doors to the bathroom, room, room

There are many different ventilation grilles on the market. All these designs differ in shape, purpose, material, size, price.

Fresh air in your home means a lot. It is not only a way to refresh the space, it is also a way to take care of the health of family members. In a room that is not regularly ventilated, a high concentration of carbon dioxide accumulates and there is a lack of oxygen. Among other things, toxic substances can accumulate in unventilated rooms, which are emitted by finishing and building materials used for repairs, as well as household appliances.

And if for most rooms of a house or apartment, the problem is quite simple to solve by opening a window for a certain amount of time on a regular basis, then with the space of the bathroom it is much more difficult.

Bathroom door ventilation: why is it so necessary?

The fact is that the bathroom is a priori a room with a high level of humidity. In addition, modern manufacturers of building and finishing materials are doing everything to ensure that this room in the house is heat, hydro and sound insulating.

Why do they do this? There are several reasons at once:

Firstly, it allows you to turn the bathroom into a completely intimate private space for everyone who is there.
Secondly, it allows you to create the effect of complete privacy.

The only, but such a significant disadvantage is that such a closed space does not provide for the penetration of fresh air into the walls. That is why every homeowner should tackle the issue of air exchange in the bathroom. One of the most effective and simplest methods is to install a grill in the door for ventilation.

Ventilation in the toilet or bathroom door

As a rule, the following rule is a classic of the genre during renovation: a small opening is left between the floor and the lower part of the door to the bathroom, which is intended for natural ventilation. However, many homeowners do not fully assess the need and need for this opening, dashingly sealing it up during repairs. Most homeowners build on a special threshold, put in a seal, and so on, citing the fact that when flooded, water will not spread throughout the house.

Taking this trend into account, modern bathroom door manufacturers are producing doors with an integrated ventilation opening. These can be either simple openings or ventilation grilles. The first option is simpler and less aesthetic, while the second looks harmoniously in the space of the door. The holes are thought out in such a way that it is hardly possible to peep from the other side of the door, which will not affect the intimacy of the bathroom space.

How to choose a ventilated bathroom door?

Finding a bathroom door with ventilation in a store that will suit both your doorway and the style of your premises in all respects is quite difficult. This is why most homeowners choose to make their own bathroom door vents. Doing it yourself is not so difficult when it comes to doors made of wood or wood-based materials. Of course, it is quite difficult to cut a ventilation hole in glass or plastic doors on your own - in the first case, you will need special equipment, in the second, skill and the absence of fear of ruining the door, since plastic is a very unpredictable material.

If you decide to make a ventilation hole in the bathroom door with your own hands, then you have two ways:

The easy way- cut the door from the bottom by a few centimeters. This method is relatively simple, but quite effective. In addition, it will not significantly damage the aesthetics of your door.
The hard way- installation of a ventilation grill in the door space. To do this, you need to purchase ventilation grilles (usually they are sold in pairs), measure them, mark the door, adding a couple of millimeters to all four sides of the product. Depending on the material of the door, select a tool to cut a hole in the door leaf and carry out the procedure. After that, it is necessary to install the grilles on both sides of the door and fix them.

This way, you can quickly and easily make your bathroom a space accessible to fresh air.

There is no person who does not realize how important high-quality ventilation in the bathroom is. The health of all family members depends on how well moisture and dampness will be eroded from this room. But how to figure out if ventilation in the bathroom performs its main functions?

Why is ventilation so important?

It is extremely important to find out, since the lack of proper ventilation in this room can lead to the development of fungus on the walls, the appearance of mold. And such unpleasant phenomena often lead to respiratory diseases, or even are a good ground for the development of oncological diseases. Many do not even know that such seemingly harmless phenomena can lead to such serious consequences.

Determine the health of ventilation

How to determine if the ventilation in the bathroom is doing the job? There are two methods used by professionals:

tear off a piece of napkin or thin paper and attach it to the ventilation grill. If this leaf sticks to the grate and does not fall off, then the ventilation is working normally;
light a match and bring it to the ventilation. The flame of the match should be deflected to the side by at least forty-five degrees. If this did not happen, and the flame simply stirred up, then the ventilation is useless and requires urgent repair.

Of course, some people decide this question too “simply”. They constantly keep the door ajar, thinking that the humid air will find a way out and not create problems. However, this is not always appropriate, and besides, the problem of dampness in the apartment cannot be solved.

Ventilation in the bathroom must perform its function efficiently. Condensation should not form on the walls and mirrors after bathing. If this happens, then it is worth considering artificial ventilation of the room.

How to choose a fan for your system?

One solution to this problem is to install an additional fan. Before installing it, it is important to accurately calculate the power of the system. How to do it?

we calculate the volume of the room: the parameters of the room (height, width and length) must be multiplied;
if no more than three people live in the room, then the resulting number should be multiplied by six;
if there are more than three people in the family, then the resulting volume is multiplied by eight.

The resulting number is the required fan power for the bathroom. Do not be tempted to install a ventilation system with a higher capacity, as this will lead to a violation of the normal temperature in the bathroom. Of course, you want to maintain a healthy atmosphere, but at the same time, no one needs the wind to blow there. Therefore, when choosing ventilation, it is important to strictly adhere to the calculations.

Ventilation system installation methods

Forced ventilation in the bathroom can perform its functions efficiently if it is simply installed on the ventilation duct itself. Usually this method consists of attaching the ventilation to the hole itself. As a rule, such fans have a pleasant appearance and small size, which means they are quite suitable for decorating a bathroom.

Overhead fans are especially suitable for bathrooms with small spaces and low ceilings. This is due to the fact that overhead ventilation systems are not initially produced with high power. This means that they will not work for spacious bathrooms.

It is important that bathroom ventilation in a private house is also performed in accordance with all norms and rules. For private houses, it is quite normal to use ventilation systems of increased power, since, due to the peculiarities of the structure, they will not interfere with anyone and will cope well with the task at hand.

As a rule, powerful ventilation systems make a lot of noise. This is their disadvantage. When installing an electrician, you can immediately take into account the possible connection of additional ventilation. Since the fans of the new design operate exclusively on electricity, they will turn on just along with the lighting. Although these two functions can be divided into two different switches. Entering the bathroom, you can turn on both the light and the fan at the same time. The system will not work when there is no need for it, which means that the room will be warm.

Additional functions of ventilation systems

Many additional useful functions have been invented for modern ventilation systems. For example, a hygrometer can be installed. When the humidity starts to reach a certain level, the fan will turn on automatically. When the indicators return to normal, the system will turn off again.

How to make ventilation on the bathroom doors?

There is an interesting option to make ventilation in the bathroom with your own hands. It can be done right in the door leading to the bathroom. There are several ways.

These are some of the options for how to ventilate the bathroom.

Ventilation in a wooden house

In recent years, houses made of wood have become increasingly popular. Not a single city dweller will refuse to spend at least a weekend in a house filled with comfort and warmth. Providing reliable ventilation in such a house is an important task. No other material will be as capricious to dampness as wood.

Ventilation of a bathroom in a wooden house should be carried out in accordance with sanitary norms and rules. Ensuring reliable ventilation in such buildings must be taken especially seriously. Due to insufficient ventilation, some structures may gradually begin to rot, and this can only be revealed after many months. It is unlikely that some owner will be pleased!

In order for the ventilation to be properly installed in a wooden house, you may need to refer to the documents drawn up by the designers. This will provide a clue to how and where the ventilation systems are best installed.

If the bathroom in the house is located on the second, that is, the last floor, then ventilation in the ceiling in the bathroom will be quite effective. You can equip duct ventilation, which will help maintain a normal indoor climate. If you choose a centrifugal fan, it will provide high-quality ventilation even for a large bathroom, although it creates certain noises.

Fan types

In general, there are four types of fans for systems. They all differ in performance, appearance and operating principle:

axial fan. It is widely used in ductless ventilation system;
diametrical fan. It does not have a high performance among fans, it is rarely used;
centrifugal fan. It is considered the most reliable and high-performance type of fans. Its only drawback is the maximum noise among similar devices;
centrifugal-axial fan. Combines the power of a centrifugal, but this type of equipment does not work as noisy. Has a more compact size.

It is obvious that installing and adjusting ventilation equipment at home is not such a difficult task. There are now many tools available more than ever to help you in this endeavor. In addition, the ventilation system can be readjusted at no cost, simply with a drill. At the very least, this will help to urgently solve the problem.

If a person serves his home in a timely manner, it will be serviceable for a long time. No one will get sick in it, as there will always be a good healthy microclimate and a positive attitude!

Fresh air in the house is the key to the well-being of the whole family, because in an unventilated room there is a high concentration of carbon dioxide and oxygen deficiency. In addition, toxic substances emitted by finishing materials and household chemicals can accumulate in the air. And, if in living quarters the problem of the flow of clean air is solved by simple ventilation, then in the bathroom and toilet the situation is different.

Not so long ago, the arrangement of ventilation in the bathroom did not attach much importance. This is not due to the illiteracy of the builders, but to the fact that over the past couple of decades, the approach to repair has completely changed. New finishing materials and building structures have appeared, which have good heat-insulating, waterproofing and sound-insulating qualities. On the one hand, this makes the bathroom completely absolutely comfortable and completely intimate space, and on the other hand, it leaves no chance for fresh air to "break through" into the room.

Earlier, when there were cracks in the wooden windows, and the doors in the rooms did not close tightly, the natural flow of air took place on its own. Today, the organization of air exchange requires a different approach. For example, in a bathroom, in addition to forced ventilation, you should take care of a door that does not impede the flow of fresh air.

Materials (edit)

Glass doors are perfect for the bathroom in terms of hydro and thermal insulation. They tolerate high air humidity, exposure to hot steam and temperature changes well. However, the glass door practically does not allow air to pass through (if it does not have special openings for this).

Doors made of plastic are similar in their properties to glass: they perfectly retain heat and do not allow moisture to pass through. Being constantly in conditions of high humidity, they do not deform or collapse. At the price, plastic doors are much cheaper than glass or wooden ones, however, in terms of aesthetic characteristics, they are inferior to them.

Doors made of natural wood are one of the most expensive options, but the most successful in terms of providing room ventilation. It is known that wood does not tolerate moisture and temperature changes very well, therefore a high-quality wooden door intended for installation in a bathroom must be treated with antiseptic agents and covered with several layers of varnish.

Laminate, chipboard and MDF doors are considered a budget option. They can be installed either to the bathroom or to any other room in the house. For such doors, there is usually the possibility of arranging the ventilation holes with your own hands. Recycled materials are coated with special solutions, so they tolerate close proximity to water well.

Types of ventilation in the door

According to the rules, there should be a small gap between the lower part of the interior door and the floor through which natural ventilation is carried out. In fact, apartment owners rarely leave this gap, fearing that in the event of a flood, water will spread throughout the apartment. Therefore, many use various seals or equip a sill before entering the bathroom. For this reason, manufacturers began to produce bathroom doors with built-in ventilation. There are two options.

Ventilation grates

The design of such a door is quite interesting: in its lower part there is a small window into which the grate itself is inserted - a frame with flat curtains located at an angle. Thus, peeping through such a grate will not work, and fresh air in the room will circulate freely. Ventilation grilles for doors are made of metal and plastic and have a variety of designs.

Ventilation holes (rings)

This is an easier and cheaper option. Through ventilation holes, as well as the grill, are located at the bottom of the door in the amount of three to four pieces. Plastic rings are inserted into the holes, which are responsible for the aesthetic component of the design. On sale you can find "advanced" models equipped with a protective noise-absorbing mesh.

As practice shows, finding a ventilated door in a store that is suitable for your bathroom is not an easy task. The choice of models is very limited (whereas, for example, it is not difficult to find a metal front door with ventilation). Therefore, we recommend that you equip the door with ventilation yourself.

To make holes for the ventilation grill or rings, it is best to purchase a door made of wood or wood processing materials. To cut a glass door, you need professional equipment, but it is difficult to predict how a plastic door will behave if you start drilling it.

If you don't want to bother buying a new door or fiddle with ventilation grilles and rings, you can use the old, proven method. Just trim the door down a couple of centimeters. If you do everything carefully, then this will not cause damage to the external appearance of the room, and the effect will be no worse than that of modern types of ventilation.

How to make ventilation in the door with your own hands?

One of the most effective ways to organize fresh air ventilation in a bathroom is a door ventilation grill. In this section, we will show you how to install it on your bathroom door yourself.

First, take a ruler and measure the ventilation grilles you purchased (usually two are included).
Then mark the door with the markings along which you will saw the hole. In this case, 1-2 mm must be added to the length and width of the grating.
Cut a hole in the door leaf of the appropriate size (tools for work should be selected depending on the material of the door).
Install ventilation grilles on both sides of the opening. Some models are designed for fastening to construction glue, while others can be fixed with self-tapping screws.

This is how you can quickly and easily install an important element of fresh air ventilation in your bathroom!

All these problems can be solved by a ventilation grill installed on the door. Today on sale you can find doors with an already built-in grille or with special ventilation holes-rings. But if the door is already installed and there is a problem with air circulation, then you just need to purchase and install the grill.

Types of ventilation grilles

The primary classification feature that determines the types of grilles is the method and place of their installation. On this basis, they are divided into:

supply air;
internal;
outdoor.

For installation on the door, supply grilles are used. They are made from the following materials:

aluminum;
plastic;
tree;
steel and others.

Aluminum gratings are quite durable, lightweight, not afraid of sunlight, but they are somewhat more expensive than plastic ones.

When installing a grill on the front door, you must choose a model with a protective mosquito net so that mosquitoes and flies do not enter the house.

Ventilation grilles let in very little light and practically exclude the possibility of viewing; it is impossible to see the person behind the door through such a structure. In shape, these products can be round, square or rectangular, but the latter option is the most common.
