Dimensions of floor, wall-hung, corner WCs

The bathroom is one of the most visited places in our house. So its arrangement is a very important thing. First of all, it is worth choosing a toilet bowl. It is easier to focus on standard sizes. You can find suitable models for almost any taste.

Types and design features

Dimensions of toilet bowls depend on the design. So it is necessary to familiarize yourself with them. At the same time, let’s find out which types can be installed in small bathrooms.

Bowl shape

Types of toilet bowls on the drain or the shape of the bowl determine the convenience of use and the level of “flavors” that can be. Also, the shape determines the minimum and maximum sizes. There are three types of bowls or flush:

• Plate or shelf type. The drain is offset closer to the front wall, and the bowl has a protrusion, which someone calls a shelf, and someone calls a plate. Hence the names of the shape. With this device, splashes will be at the flush, which is unpleasant, but at least you will not feel them. However, the toilet bowl with a shelf is the most “fragrant”. Excrement remains “on the shelf” until it is flushed, so the odor is intense.
• Gooseneck. The drain is also closer to the front wall, but the back wall of the bowl is flat, with a slight slope towards the drainage funnel. With this design, the waste gets on the back wall and slides down it into the water. There is no splash, the odor is present, but not so intense. Traces remain, although the main source is in the water.
• Funnel-shaped. The shape of the bowl of such a toilet bowl is similar to an ordinary funnel. The drain is almost in the middle. There will be almost no odor, but you will feel the splash. Literally. You can fight with splashes either by moving forward/backward, as the dimensions allow (yours and the toilet bowl), or throwing a piece of toilet paper into the water beforehand.

Which toilet bowl is better to choose? In general, not bad visor. Without splashes, with a tolerable level of “aroma”. True, after each use you will have to use a ruff. But you quickly get used to this procedure.

Method of installation

According to the method of installation, there are two types of toilets: floor and suspended. With floor ones, everything is clear, they are installed on the floor and fixed to it. They are of two types. The first – the usual for us with a cistern on a remote shelf or with a cistern on the wall. The second type is wall-mounted. This option we have recently appeared. It differs in that the back wall is almost completely parallel to the wall.

Suspended or built-in toilet bowl is not attached to the wall, as it may seem, but to the design, which is hidden behind a false wall. This structure is called an “installation”. It is a metal frame, which is fixed with bolts to the walls and to the floor. And already on this frame is attached not only the bowl, but also the button, and all the pipes.

Release

This is not all the design features. It is still necessary to deal with the outlet. This is the outlet, through which the toilet bowl is connected to the sewerage system. The most compact models with a vertical spigot outlet. The longest with oblique. But they are more common, since it is not necessary to raise the sewer pipe, and you can only put a tee, and in it lead the corrugation.

Forms of toilet bowl outlets are also three: straight, oblique and vertical. Vertical is now a great rarity, although if desired, you can find them. This standard is used in America. But everything is possible under the order. It is the toilet bowl with a vertical outlet will have, by the way, the smallest “depth”. And with such an outlet usually make wall-mounted models.

How to choose a toilet bowl by outlet? If you just change the toilet bowl, and you do not plan to remodel the sewer system, there is no choice, in fact, there is no choice. You need one with the same outlet that was there. No variants. When replacing the sewer pipes in the apartment will be able to change the oblique to straight, or vice versa – straight to oblique. But put vertical will not work – the drain must go vertically down, that is, to your neighbors below. This means that you will have to make a replacement and at them. When should you choose a vertical drain? In a private house – better on the first floor. In the subfloor or basement, the pipe will not interfere with anyone. And the plus of this type has already been voiced – it is a minimum “depth”.

Types of cisterns for the toilet bowl

Before dealing with the standard dimensions of the toilet bowl, you still need to think about the type of cistern. This also affects the size. For example, the popular compact model, far from being the most “short”. Here the palm of superiority is with models with a separate wall-mounted cistern. But you still need to take into account the pipe with which the cistern and toilet bowl are connected.

In general, there are three types of toilet cisterns: separate (wall-mounted), compact and monobloc. Compact and monobloc can be straight or angular. Corner models, as a rule, are the smallest. And they definitely allow you to save space in a small toilet.

What are the differences between the cisterns? There is no fundamental difference. It is a matter of preference of the owners, well, and in appearance. Monoblock is when the bowl and cistern are molded in a single form and can not be separated. Compact – this is when the tank is installed on the back of the bowl. In such models, the bowl has a special outlet behind with holes for fixing the cistern. What is good about this option? You can change the cisterns. Not only if the old one cracked, but also if you miss the shape or volume. This also happens. The same advantages of wall-mounted cisterns. With the only difference that you will have to fix them and install a connecting pipe.

There are, by the way, toilets without cisterns. These are not those in which they are hidden in the installation, but those that are directly connected to the water supply. This model is used in Germany, and we also have it in some public toilets. Its main advantage is saving space. However you look at it, the cistern takes up space. If the space is very poor, you can put one of these. However, provided that the pressure for its operation in your system is enough.

Distances

Good for those who have a large room for a bathroom or toilet. If it is not so large, you need to know the minimum tolerances for the distance from the toilet bowl to nearby “structures” and devices.

• There should be at least 25 cm between the bidet and the toilet bowl.
• There should be at least 60 cm of free space in front. That is, the distance from the edge of the bowl to the door or wall in front is 60 cm or more.
• On the sides there should be at least 25 cm of free space. This is not enough, but it is tolerable. The comfortable distance is 35 cm.

Now you draw a plan of your bathroom, mark the minimum distance and see what size toilet bowl will stand in your toilet. So everything is simple.

Standard sizes of the toilet bowl and the minimum size of the toilet

GOST 30493-96 norms the size of only toilets with a shelf. There are still those that are installed in cars, but we do not need them. Standard sizes of a toilet bowl with a shelf are prescribed for two variants: with a solid-cast and with an attachable one. The second model is used in a set with hinged/wall-mounted cisterns or without them at all. There are also standard sizes of children’s toilet. They (children’s) come without a shelf. All sizes are given in the table. And to understand what we are talking about, we look at the drawings.

So, the standard size of the toilet bowl with a shelf (called usually “Compact”):

• Length – L – 605 mm. This is taking into account that the model is compact with a ledge for the installation of a cistern. It is separately prescribed that it is possible to produce shorter models up to 575 mm in length.
• Width – B – also two standard values: 340 and 360 mm.

The height of WCs is not normalized, but usually within 370-390 mm. So according to the standard, the narrowest toilet bowl – 340 mm, and the shortest model “compact with shelf and oblique drain” – 575 mm. Based on these values and the minimum allowable distances from the previous paragraph, we can determine the minimum dimensions of the toilet for the installation of such a model. Let’s start with calculating the width: 340 mm + 2*250 mm = 840 mm. That is, the distance between the walls can not be less than 84 cm. Better, of course, more.

And the length of the toilet should be 575 mm + 600 mm = 1175 mm. But this is without taking into account the fact that you still need to lay the sewer pipe and somehow connect the drain. For this we will allocate another 20 cm. Total we get that the minimum length of the toilet room is 1175 mm + 200 mm = 1375 mm. In meters it is 1.375 m.

Standard dimensions of the toilet bowl with a wall-mounted cistern are significantly smaller: length / depth 460 mm, width 360 mm and 340 mm. That is, the room can be shorter. Its minimum depth is 1060 mm – this is only for a comfortable installation of the bowl, but you still need to connect the pipes, so add another 20 cm. Total, we get that to install a toilet bowl with a wall-mounted cistern, the room should be at least 126 * 84 cm. And if you have a longer room, you can move the miracle of plumbing back, and behind the toilet and / or above it to make a cabinet with shelves.

What sizes there are toilet bowls

Standard sizes of the toilet bowl are designed for people of average height and build. Not everyone is like this. Yes, and a toilet bowl with a shelf, which is described in GOST, is far from the best choice in terms of aromas. And also, in stores today, most of the imported products. And they have their own standards. For example, the European standard size of the toilet bowl is 680*360*400 mm (this is the length, width in the widest part and the last digit – height). The Americans went even further – they have the usual “depth” is 768 mm, width 380 mm, the height of the rim above the floor is the same – 36-38 cm. As you can see, the standards are different, and not everyone makes according to the standards. People have different demands and the market is trying to satisfy them.

Dimensions of floor models

As you understand, floor models of toilets are different and their sizes are also different. Here is the range, but we do not guarantee that there are no narrower or wider ones. Most likely, if you set your mind to it, you can find both.

Compact

The toilet bowl of the Compact type (with a cistern, which is attached to the back) has the following dimensions:

• length – 610-645 mm;
• width from 345 mm to 420 mm;
• height from 370 mm to 395 mm.

Note that the narrowest bowls are more like a rectangle. They are not as rounded as we are used to. It is quite convenient to use them. Only there may be problems when buying a lid. This shape is not often found.

Without a cistern

A toilet bowl without a shelf with a hinged or separate cistern has the following dimensions:

• length 435-460 mm (20 cm less than Compact models!);
• width 360-400 mm;
• rim height from the floor level 350-390 mm.

As you can see, they are more compact, despite the name given to the previous variant. But such models are less popular, since the cistern must be fixed, and this is an additional headache. And earlier this type was considered a “relic”, now – it is stylish and interesting. There are very interesting models (though, and they cost interesting).

Monoblock

There are also floor toilets Monoblock. They are also mostly wall-mounted. These are those in which the cistern and bowl are not detachable and one is an extension of the other. The dimensions of Monobloc toilets are as follows:

• length – 665-720 mm;
• width (usually the cistern is wider, but not always) – 360-420 mm;
• height
  • from the floor to the top of the lid – 700-870 mm;
  • from the floor to the rim of the bowl – 360-390 mm.

These models are not small. Perhaps that is why they are not too popular in our country. No matter how you spin it, it is easier to bring the bowl and cistern separately than the whole construction. But the probability of leaks is less.

Dimensions of suspended models

With suspended toilets, you need to look at the size of the bowl and installation. They usually come in a set. And, as a rule, more questions arise with the installation. Actually, the size of the installation depends on the planned load. External unreliability and fragility are deceptive. A suspended toilet bowl with a reinforced frame can withstand a weight of up to 400 kg, standard designs – up to 200 kg, and super strong – up to 400 kg.

The dimensions of installations for suspended WCs are as follows:

• height – 1100-1250 mm;
• width – 400-550 mm;
• depth – 140-250 mm.

These are average values. There are also narrow installations – they can be from 345 mm. True, their “carrying capacity” is about 120-150 kg. And those that are found, most often about 50 cm wide. As you can see, they do not take up too much space.

Now about the dimensions of the bowl of suspended toilets. It has these dimensions:

• length 480-560 mm;
• width 356-430 mm.

The height of the bowl of the suspended toilet bowl can be different. It depends on the style. There are bowls almost flat, height 290-320 mm, there are medium – 340-365 mm. And they have a very different look: square, rounded, oval, narrowed to the bottom or rounded, more like a puck.

There may still be questions about the height at which to place the suspended built-in toilet bowl relative to the floor. Do not worry. The height will be “chosen” automatically. It will depend on the dimensions of the bowl and the location of the hole for the sewer outlet in the installation. You will only need to make sure that they were compatible (of the same size and that the bottom part of the bowl does not “lie” on the floor).
