The sizes of the bath: standard and optimal

In most standard apartments, the bathroom has relatively small dimensions. For this reason, every inch of free space should be used to maximum benefit. In the huge variety of different bathtubs is quite difficult to understand, because they all differ in size, materials used and design.
How to choose the most suitable bathtub?
The main indicator that directly affects the choice of bathtub is its size. It is worth bearing in mind that in addition to the bathtub itself, a small room may have a sink and other interior objects.

The most optimal size will be the bathtub, in which you can safely take a half-lying position. It is important to leave the opportunity to stretch out his legs, and the water level should be above his knees. When choosing the width, it is necessary to take into account your build and in addition leave 5 cm on all sides. The following picture shows how the posture changes depending on the size of the bathtub.

Dimensions
Most bathtubs are between 50 and 60 cm deep. This height is the most acceptable, because when lying down your head will always be above the water level, and get out of the bath will not be difficult. When choosing a large-sized bath, it is worth bearing in mind that it will take a considerable amount of time to set the water.
