In the construction industry, not only equipment but also models and product numbers using alphanumeric characters are often read separately for each character in order to prevent misunderstandings and accurately convey information such as dimensions. In many cases, D is "day", T is "te", V is "buoy" instead of vie or vee, and W is "double" instead of double. For this reason, it is difficult to hear in 1418 due to the friction noise.ToothIt is rarely expressed as "Ichihachi" or "Senyonhyakujuhachi" as a numerical value.

The 1418 designation, which indicates the dimensions of unit equipment, generally refers to the width and length of equipment, and in unit baths, it is used as an approximate dimension of frontage and depth, which indicates the size of space.

The frontage used to express the size of a space refers to the dimension that can be seen in front when a person stands upright, and in a narrow space it is often used as an expression based on the doorway, and the position of the bathroom in the house is Determined by various requirements.

Family-friendly residential-scale bathrooms such as 3LDK and 4LDK have a space for undressing in front of the flow line from the common space such as corridors and halls and the aisle space to the bathroom. In addition, in studio-type condominiums that are often used for singles, the dressing room is omitted and there is a floor plan for entering and exiting the bathroom from the corridor, etc., and the entrance is located on either side of 1418 or 14 It depends on the floor plan, and either 18 or 14 is not always the explicit frontage dimension. If you want to specify either explicitly, put the depth dimension behind and use the acronym for depth, which means depth in English, on the shoulder of the number 18x14.DOr 18 × 14DIt is often expressed as.


In terms of dimensions, 1418 (14 x 18) has a width of 1.4 for the entire bathroom including the washroom and bathtub.Meters, The depth is 1.8 metersmeaningIs. The size of 1620 (16 x 20) means that the width of the entire bathroom including the washing area and bathtub is 1.6 meters and the depth is 2.0 meters.

The dimensional information obtained from the 1418 name is 1,400 mm in the short side direction and 1,800 mm in the long side direction, excluding the protruding part inside the equipment unit, but in the name and the actual product, the internal method is as the name implies. There are many products with fluctuations in the name of plus or minus 50 mm from the dimensions, and it is often judged as a rough dimension at the practitioner level. In addition, the shape of the bathtub inside the bathroom can be roughly divided into a Western-style type that allows you to extend your knees inside the bathtub and a Japanese-style type that allows you to immerse yourself while holding your knees. There are products with few items, and although the nominal size is a guide for the size, it is difficult to judge the specifications and condition of the equipment unit.

Actual dimensions

in JapantatamiBeginning withShakunuki methodThere are many items of shaku modules based on the above, such as futons, chests of drawers, and desk furniture, and some chests that store Japanese clothes can only be stored in shaku modules. Even in Japanese detached houses, the pillar division using the shaku module by the shakukan method remains persistent, and the wall arrangement tends to be divided equally by 455 mm, which divides the pillars into two equal parts based on the shaku module, and 303, which divides into three equal parts. There is. For example, if the cross-sectional dimension of the columns is 100 mm and the column spacing is 3 shaku = 910 mm, the internal dimensions are 910-100 = 810 mm, and if the column spacing called the meter module is 1 m, the internal dimensions between the columns are 1,000-100 =. It will be 900 mm. The combination of numbers, which at first glance seems to be irregular, is often determined by such a dimensional background and the way of thinking of architectural planning.
