Possible installation sites
There is also nothing complicated here, since most often the cabin implies not so many installation options.
For example, for small rooms, the most convenient point is the installation of the cab in the corner of the room, because the remaining area is more rationally consumed. If there is a niche in the bathroom, then, of course, you need to consider the possibility of installing the cabin in this place. The main thing is to understand that it is undesirable to make the cabin area less than 80 by 80 centimeters, because it will be very inconvenient and uncomfortable to use such a small shower.
