When choosing plumbing, it is necessary to take into account a lot of various nuances, a fairly good choice of various plumbing offers a plumbing revision, you can choose many different plumbers for every taste suitable for any interior solution.
However, often many people incorrectly evaluate the capabilities and features of the room in which plumbing will be installed. For example, at the moment, a corner bathroom is quite popular, but such a bathroom will be relevant only in a large room, and a small room, such a bathroom will be quite uncomfortable and, in fact, a completely useless waste of space. In addition, it is not worth calculating that the corner bathroom is large, it seems large only because of its width, such a bathroom can be called rather wide than just big.
If your room, which is allotted under the bathroom, does not have a fairly large size, then the best option would be to install the bathroom of the usual size or just put a good shower cabin.
I want to say separately about the sink in the bathroom. Many do not install it, thereby saving a useful space, but this is a mistake. The sink in the bathroom will not take up much space, but it will be useful. For washing or brushing your teeth, such a sink is simply indispensable, it is simply inconvenient to do it in the bathroom.
As for kitchen plumbing, then you also need to take more attentive to the choice of plumbing. For example, a sink, it must be chosen in a deeper way, in a deep sink it will be quite convenient to wash the dishes and so on. The deep sink is also quite convenient, in addition, the sink should be wide and roomy. Deep and roomy kitchen sink will be a fairly convenient assistant.
