Standard bathroom dimensions - characteristics of acrylic, cast iron and steel models

The bathtub is the central element of the design of the bathroom, from which the interior of the rest of the room “plays”. The style and design of the bathroom depends on the shape, size, material from which it is made, the color of this element.

Since bathrooms in apartments and private residential buildings vary greatly in size, manufacturers produce washing containers of different lengths, widths, depths, suitable for a spacious room or a three-meter room. Ease of use, quality of installation of this product depends on the correct choice of shape and dimensions. In this article, we will tell you what are the sizes of cast iron, steel and acrylic bathtubs to make it easier for you to choose.

Criterias of choice

The dimensions of the bathtub of the standard model are values ​​\u200b\u200bthat indicate the length, width, depth of the product. For the convenience of customers, the size range of cast iron, steel and acrylic wash containers is standardized, however, there are models with atypical sizes. Bath dimensions depend on the shape of the product, they are developed taking into account the average physique of an adult. It is believed that for comfortable use, the width of the product intended for the adoption of hygiene procedures should be at least 60-85 cm, depth 60-65 cm, and length 150-180 cm.

When choosing the size of the bathroom, consider the following factors:

  • The dimensions and shape of the model are selected in accordance with the area of ​​\u200b\u200bthe bathroom. Solid does not allow the use of this option in small spaces. After placing a washing container, necessary plumbing, furniture and household appliances in the bathroom, there should be a place in it for comfortable movement of a person.
  • When choosing, it is taken into account that the volume of standard acrylic, cast iron or with the same dimensions can differ significantly, since this parameter is influenced by the shape of the model, the angle of inclination of the walls.
  • For safe operation, bathtubs with a depth of up to 60 cm are chosen so that when immersed in water, the person's head remains above the liquid level. This size is also convenient for getting in and out of the tank.
  • The width of the model is selected in accordance with the build of the people using it, so that when immersed, a few cm remain from the bathtub wall to the user's shoulder.

Note! To ensure that the bath does not sway, play or stagger after installation, it is necessary to accurately select the dimensions of the model. If the container is mounted from wall to wall, then the length of the product should correspond to this distance minus 3-5 cm. It is desirable that the gaps between the wall and the edges of the bath be minimal, since waterproofing these places is quite problematic.

Cast iron products

Despite the weight of 100-150 kg, they are in demand among buyers due to their excellent performance and affordable price. This material has high strength, wear resistance and low thermal conductivity, thanks to which it perfectly retains heat during use. Cast iron is considered a material that is difficult and difficult to process, so the standard sizes of bathtubs from it are limited to 3 categories:


Note! Some manufacturers offer non-standard dimensions of a cast iron bathroom - 70x170 cm or 70x180 cm. When buying these models, it should be borne in mind that not every room will accommodate a container of such dimensions. In addition, the weight of large cast iron models exceeds 150 kg, which causes inconvenience during transportation and installation.

Steel products

Compared to other materials from which bathtubs are usually made, steel stands out for its affordable price and high wear resistance. It must be admitted that it retains heat worse than cast iron, but it weighs 3 times less, which greatly simplifies the transportation and installation of this product. A steel bath is stronger than acrylic, however, manufacturers do not recommend sitting on the sides of such models, as they can be deformed. When buying, it is worth considering that steel has a high resonating ability, and therefore a set of water creates a lot of noise.

The dimensions of a standard steel bath are:

  • The length of a steel bath, according to the standard, can be 150-180 cm. The longer the model, the more comfortable it is.
  • The width of steel models is 70-85 cm.
  • The depth of steel products is 65 cm.

Important! The steel used for the manufacture of bathtubs has a higher ductility than cast iron, so it is easier and more convenient to process this metal. Therefore, the range of steel products is wider and more diverse, it includes oval, rectangular, round and angular bathtubs.

acrylic products

Recently, the popularity of acrylic products has increased, bathtubs made of this material are distinguished by a beautiful glossy sheen, flawless whiteness, low heat transfer coefficient and a variety of colors. Not the last place among the advantages of these models is the abundance of various shapes and sizes offered by manufacturers. The size range of acrylic products is very flexible, it does not comply with the standard. The length and width of acrylic bathtubs is difficult to determine, as they often have a rounded, curvilinear shape.

When choosing such products, consider the following factors:

  • The length of the bath of a standard model made of acrylic is 120-190 cm, and the width is 70-170 cm. Due to the depth of 65 cm and the steeper angle of the walls of the product, the volume of the tank is greater than that of cast iron and steel models.
  • The main factor in the comfort of acrylic models is academic. The most comfortable bathtubs are made taking into account the shape of the human body, they are equipped with built-in headrests, handrails, a corrugated bottom surface to increase comfort during operation.

Important! Contrary to popular belief, the dimensions of the standard acrylic bathtub make it possible to use this product not only in rooms with a large area. Compact with a length of 120-130 cm, they fit optimally into small-sized bathrooms, since almost vertical walls, complete with sufficient depth, increase the volume of the tank, increasing the convenience of taking water procedures.
