Standard sizes of a toilet bowl: with a tank, installation, suspended

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

Types and design features

The dimensions of the toilet bowls depend on the design. So it is necessary to familiarize yourself with them. At the same time, we will find out which types can be installed in small bathrooms.

bowl shape

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

• Plate-shaped or with a shelf. The drain is shifted closer to the front wall, and the bowl has a ledge, which someone calls a shelf, and someone calls it a plate. Hence the name of the form. With such a device, there will be splashes when draining, which is unpleasant, but at least you won’t feel them. However, a toilet with a shelf is the most “fragrant”. Excrement remains “on the shelf” until it is washed off, so the smell is intense.
• Kozyrkovy. The drain is also closer to the front wall, but the back wall of the bowl is even, with a slight slope towards the drain funnel. With this design, the waste falls on the back wall and slides along it into the water. There is no splash, the smell is present, but not so intense. Traces remain, even though the main source is in the water.
• Funnel-shaped. The shape of the bowl of such a toilet is similar to a regular funnel. Drain almost in the middle. There will be almost no smell, but you will feel the surge on yourself. Literally. You can fight splashes either by moving forward / backward, as the dimensions allow (yours and the toilet bowl), or by first throwing a piece of toilet paper into the water.

Which toilet is better to choose? In general, a good visor. Without bursts, with a tolerable level of “aroma”. True, after each use you will have to use a brush. But you quickly get used to this procedure.

Installation method

According to the installation method, there are two types of toilet bowls: floor and hanging. Everything is clear with the floor ones, they are installed on the floor and fixed to it. They are of two types. The first one is familiar to us with a tank on a remote shelf or with a tank on the wall. The second type is wall-mounted. This option has just been introduced to us. It differs in that the back wall is almost completely parallel to the wall.

A hanging or built-in toilet is not attached to the wall, as it might seem, but to a structure that is hidden behind a false wall. This design is called “installation”. This is a metal frame that is bolted to the walls and to the floor. And already on this frame, not only the bowl is attached, but also the button, and all the pipes.

Issue

These are not all design features. Still need to figure out the release. This is the outlet through which the toilet is connected to the sewer. The most compact models with a vertical spigot outlet. The longest with an oblique. But it is they who are more common, since it is not necessary to raise the sewer pipe, but you can only put a tee, and insert a corrugation into it.

There are also three forms of toilet outlets: straight, oblique and vertical. Vertical ones are now very rare, although you can find them if you wish. This standard is used in America. But under the order everything is possible. It is toilets with a vertical outlet that, by the way, will have the smallest “depth”. And with such a release, wall models are usually made.

How to choose a toilet according to the release? If you are just changing the toilet, and do not plan to redo the sewer, there is actually no choice. You need with the same release that was. No options. When replacing sewer pipes in an apartment, it will be possible to change an oblique to a straight line, or vice versa – a straight line to an oblique one. But it will not work to put a vertical one – the drain should go vertically down, that is, to your neighbors below. This means that they will have to make a replacement. When should you choose a vertical drain? In a private house – better on the ground floor. In the underground or basement, the pipe will not bother anyone. And a plus of this type has already been announced – this is the minimum “depth”.

Types of cisterns for the toilet

Before you deal with the standard dimensions of the toilet, you also need to think about the type of tank. This also affects the dimensions. For example, the popular compact model is far from being the “shortest”. Here the palm is for models with a separate wall-mounted tank. But we must also take into account the pipe with which the tank and the toilet are connected.

In general, there are three types of toilet bowls: separate (wall-mounted), compact and monoblock. Compact and monoblock can be straight or angled. Corner models are usually the smallest. And they certainly allow you to save space in a small toilet.

What are the differences between the tanks? There is no fundamental difference. It’s about the preferences of the owners, well, and in appearance. A monoblock is when the bowl and tank are cast in a single mold and cannot be separated. Compact is when the tank is installed on the back of the bowl. In such models, the bowl has a special outlet at the back with holes for attaching the tank. Why is this option good? Cans can be changed. Not only if the old one cracked, but also if they missed the shape or volume. This also happens. The same pluses and at wall tanks. The only difference is that you have to fix them and install a connecting pipe.

There are, by the way, toilet bowls 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, we also have it in some public toilets. Its main advantage is space saving. Like it or not, the tank takes up space. If space is really bad, you can put one. True, provided that there is enough pressure for it to work in your system.

Distances

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

• There must be at least 25 cm between the bidet and the toilet.
• There must be at least 60 cm of free space ahead. 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 free space of at least 25 cm. This is not enough, but tolerable. Comfortable distance – 35 cm.

Now draw a plan of your bathroom, mark the minimum distances and see what size the toilet will fit into your toilet. So everything is simple.

Standard toilet dimensions and minimum toilet size

GOST 30493-96 normalizes the dimensions of only toilet bowls with a shelf. There are still those that are installed in wagons, but we do not need them. The standard dimensions of a toilet bowl with a shelf are prescribed for two options: with a one-piece cast and with an attached one. The second model is used in a set with mounted / wall-mounted cisterns or without them at all. There are also standard sizes of a children’s toilet bowl. They (children’s) go without a shelf. All dimensions are shown in the table. And to understand what we are talking about, we look at the drawings.

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

• Length – L – 605 mm. This is taking into account the fact that the model is compact with a ledge for installing a tank. Separately, it is written that shorter models up to 575 mm long can be produced.
• Width – B – also two standard values: 340 and 360 mm.

The height of the toilets is not standardized, but usually within 370-390 mm. So, according to the standard, the narrowest toilet bowl is 340 mm, and the shortest “compact with shelf and oblique drain” model is 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 by calculating the width: 340mm + 2*250mm = 840mm. That is, the distance between the walls cannot 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 it is also necessary to lay the sewer pipe and somehow connect the drain. We will allocate another 20 cm for this. In 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.

The standard dimensions of a 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 let’s add another 20 cm. In total, we get that to install a toilet bowl with a wall-mounted cistern, the room must be at least 126 * 84 cm. if your room is longer, you can push the miracle of plumbing back, and make a cabinet with shelves behind the toilet and / or above it.

What are the sizes of toilets

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

Dimensions of floor models

As you understand, floor models of toilet bowls are different and their sizes are also different. We will give a range, but we do not guarantee that there are no narrower or wider ones. Most likely, if you set a goal, you can find both.

Compact

A toilet bowl of the Compact type (with a cistern mounted at the back) has the following dimensions:

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

Please note that the narrowest bowls are more like a rectangle. They are not as round as we are used to. They are quite convenient to use. Only there may be problems when buying a cover. This form is rare.

Without tank

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

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

As you can see, they are more compact, despite the name given to the previous version. But such models are less popular, since the tank 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 they cost interesting).

Monoblock

There are also Monoblock floor standing toilets. They are mostly wall-mounted. These are those in which the tank and bowl are one-piece and one is a continuation of the other. The dimensions of the Monoblock toilets are as follows:

• length – 665-720 mm;
• width (usually the tank 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 very popular with us. Whatever one may say, it is easier to bring the bowl and tank separately than the entire assembly. But the chance of a leak is less.

Hanging model sizes

For hanging toilets, you need to look at the dimensions of the bowl itself and the installation. They usually come as 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 wall-hung toilet with a reinforced frame can withstand weights up to 400 kg, standard designs up to 200 kg, and super-strong designs up to 400 kg.

The dimensions of installations for hanging toilets 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 are most often about 50 cm wide. As you can see, they do not take up too much space.

Now about the size of the bowl of hanging toilets. It has the following dimensions:

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

The height of the bowl of the wall hung toilet may be different. Depends on the style. There are bowls almost flat, 290-320 mm high, there are medium ones – 340-365 mm. Moreover, their appearance is very different: square, rounded, oval, narrowed to the bottom or rounded, more like a washer.

There may be more questions regarding the height at which the wall-mounted built-in toilet should be placed relative to the floor. No worries. The height will be “selected” 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 are compatible (the same size and that the bottom of the bowl is not “lying” on the floor).
