What are the dimensions of the toilet bowl

The toilet bowl is a sophisticated sanitary item composed of multiple components. Each element serves a specific purpose and possesses unique characteristics. Nonetheless, height, width, and depth are the three critical factors that most customers consider important.

What sizes exist?

When it comes to size, toilets can be classified into two distinct categories – those designed for adults and those tailored for children. The former are commonly found in residential properties, as well as in state, municipal, and private establishments. On the other hand, the latter, which are comparatively smaller in size, are primarily installed in children’s facilities such as kindergartens and hospitals. Additionally, individuals who own cottages with multiple bathrooms, some of which are specifically intended for children, may also opt to purchase these child-sized toilets.

Are there standards?

Sanitary ware and sanitary porcelain toilets do not require mandatory certification, but they must meet certain standards. The most recent GOST (Russian national quality standard) was established in 2017 to account for the advancements in plumbing technology, construction regulations, and consumer preferences.

In accordance with these standards, there are different types of toilets based on their attachment method:

• floor-mounted toilets, including models designed for children;
• wall-mounted toilets.

According to the GOST, floor toilets should have a solid shelf and a funnel-shaped bowl, with a horizontal, oblique (at a 45-degree angle), or vertical outlet.

The standard dimensions for these toilets, specified in height x length x width (in cm), are as follows:

• for children – 33.5 x 40.5 x 29;
• for adults – 40 x 60.5 x 34 and 36.
• wall models – 35x45x60x740 and 360;
• copies without a solid-cast shelf – 40x46x36 cm.

Much more uncommon, however still available for purchase, are plate and visor WCs, as well as WCs with a suspended cistern. In Russian apartments and institutions there still exist such variations, as specified by domestic GOSTs of 1985 and 1996.

What do the dimensions affect?

Every object is created in a form and size that ensures its optimal functionality. As adults and children differ in height and weight, the dimensions of chairs for different age groups also vary.

The height of a toilet bowl is designed to suit an average person and usually reaches the knee level. It is crucial for the user to feel comfortable while sitting on it, which means that their legs should not dangle but firmly touch the floor to avoid strain.

The width and depth of the seat should also ensure that the buttocks remain nicely positioned. The ideal measurements of the bowl prevent it from having inward or outward irregularities.

The depth (or length) is the most variable aspect and depends on whether a cistern is attached to the body and its size.

Popular types of toilet bowls and their dimensions

Plumbing companies create a variety of models with distinctive designs, installation locations, fastening techniques, and element connections. These models adhere closely to industry standards, allowing for slight deviations.

Compact

The traditional style of a floor toilet features a single-piece design, consisting of a bowl with a base and a shelf with a tank. Various manufacturers offer "adult" models with seat heights ranging from 39 to 41 cm, bowl lengths from 42 to 49 cm (including lid fasteners), and widths from 34 to 37 cm. Water can be supplied from below or from the side. These toilets are secured to the floor using anchor bolts, allowing them to be installed at any distance from the wall, as long as there is access to sewage and cold water pipes. This option is the most commonly used, affordable, and suitable for DIY installation.

Suspended with installation

A rather "new" category. It is fixed onto a metal framework connected to the main wall and floor using anchor bolts, capable of supporting a weight range from 250 kg to 500 kg. Concealed within the installation is the cistern. The exterior is covered, with only the flush handles extending beyond. It is not affixed to the floor, making it easier to clean and visually occupying less space compared to floor-mounted alternatives. Many installations offer height adjustment, enabling even a basketball-loving family to install it slightly higher. The dimensions are designed to fit standard measurements.

Attached (wall-mounted)

They are positioned on the ground, with the back vertical surface fitting snugly against the wall, concealing all pipes and fixtures behind the smooth, shiny surface of the ceramic or porcelain base. It can be installed with a cistern in two ways:

• on a shelf;
• concealed within a fake wall.

The connections between the toilet and the wall as well as the floor are sealed with a sealant. The dimensions are approximately in accordance with the GOST standards.

Corner

An alternative version of the previous design features a rear section that has been angled to create a sharper appearance. This type of design has become increasingly popular in recent years. Corner toilets, like closets and kitchen corners, offer a space-saving solution without sacrificing comfort. Installing a toilet bowl in the corner also provides convenience, as it ensures that there is no risk of hitting anything on either side due to the expanding space from the corner.

Monoliths

One-piece toilets have a unified design with the bowl and cistern combined together. This gives them a visually appealing appearance, but it also presents a challenge when it comes to repairing the cistern in case of any malfunctions. Additionally, their weight can reach up to 500 kg, making the transportation and installation process more difficult.

Without a cistern

Germany widely uses these drain-connected designs, which help conserve resources. However, they may not flush effectively under low pressure in the cold water pipe.

If you have done renovation work and have decided to change the plumbing in your bathroom, there are some important guidelines to consider when choosing a toilet for your toilet or combined bathroom. In order to ensure maximum comfort when using the toilet, it is important to:

• First, you should measure the available space in which you plan to install the toilet bowl. Make sure there is at least 60 cm of space in front of the unit. On the sides, there should be a minimum of 40 cm from the center line of the bowl (approximately 22 cm from the edges)
• Consider the size of the largest member of your family to ensure they can comfortably use the toilet bowl.
• Take a look at the different toilet bowl options available on the market and choose a model that meets your needs and preferences.

For example, if you want to install a compact toilet bowl with dimensions 40x60x36, you will require a rectangular space with sides measuring 120 and 80 cm. If you have less space available, you may want to consider a smaller model or one with a wall-mounted tank.

When suspended or mounted on the wall, copies of this item will occupy the same amount of space as a compact version. However, visually, due to the concealed communication and cistern within the false wall, it will create the illusion of saving space.

An ideal option for installing a corner model is a square "patch" that measures one meter by one meter. The model should have a length of 75 cm and a width of 36 cm.

By the way! In case you have only purchased a toilet bowl, you will need to purchase other components for the setup: a cistern, installation materials, fasteners, and a lid. However, if you invested in a complete package, you won’t have to worry about this.

After bringing the new toilet bowl from the store to your apartment and installing it in the bathroom, it should be accompanied by small items that will be essential for users. These items include:

• a toilet paper holder;
• a toilet brush in a designated holder;
• a shelf for detergents and cleaning products.

All of these accessories should be conveniently placed, allowing for easy access and use when needed.

Parameters of the cistern

When it comes to toilet cisterns, there are two main options: compact and monolithic models, where the cistern is "attached" to the toilet bowl, and other cases where you can choose the cistern separately, allowing you to select your preferred brand and model. However, it’s important to consider compatibility with the bowl, as well as the methods of water supply and connection to the sewerage system before making a purchase.

Here are the approximate dimensions of cisterns for different types of toilets:

• Compact cisterns: width – 16 to 18 cm, length – 35 to 37 cm, height – 37 to 40 cm;
• Suspended cisterns (with installation): 14-23×29.5-41×36-48 cm;
• Corner cisterns (conventionally triangular shape): sides – 30x30x43 cm, height – about 40 cm;
• Medium and high suspended cisterns: 13x40x35 cm.

Tips for installing the toilet bowl

1. Make sure to check the availability of all necessary spare parts before making a purchase, and if any are missing, purchase them separately as needed.
2. You can install a floor toilet yourself by strictly following the instructions provided. However, it is recommended to hire specialists for the installation of a wall-hung toilet.
3. Ensure that the product has free access during the installation process.
4. Install the design on a level floor. Any small irregularities can be corrected using silicone sealant.
5. When installing wall-mounted models, it is crucial to align the technical holes in the wall and plumbing perfectly. Remember the rule: "Measure seven times, cut once".
6. If necessary, utilize flexible hoses and corrugations.
7. The height of the toilet seat from the floor should be comfortable and at least approximately meet the standard requirements.
8. Assembling the cistern (if needed);
9. Installing the sewage system;
10. Placing the toilet bowl in position;
11. Marking and drilling holes for fastening;
12. Installing the product (and cistern);
13. Connecting the cold water supply pipe.

If the model is wall-mounted, the installation should start with mounting the concealed fastener.

The sequence of actions when installing a wall-mounted toilet bowl with a support frame:

• Marking;
• Securing the support frame to the floor and wall;
• Adjusting the holes for fastening the toilet bowl at the desired height;
• Connecting the cistern to the water supply system;
• Attaching the toilet bowl to the fittings and connecting it to the sewer hole;
• When installing the external cladding, it is important to consider the drainage holes and release keys on the cistern.
• One of the tasks during the installation process is to properly fit the necessary components.

In the era of rapidly advancing innovative technologies, new, more user-friendly and functional sanitary ware models, including those with electronic control, have emerged. However, all of these models are still manufactured according to approved design plans, ensuring high quality and safety of usage. Despite the minimal changes in the growth and dimensions of the average person over the years, the approximate height of the toilet bowl from the floor and the basic bowl dimensions have remained the same for over half a century.
