That in old houses

Of course, if the bathroom is large and ventilation is perfectly established in it, then it is much easier to solve this issue — any material is suitable for the door, it does not matter how moisture -resistant it is. But, unfortunately, quite large bathrooms can be found only in private houses or in apartments with a free layout, where you can independently decide what size this or that room will be. But what are the typical high -rise buildings, that in old houses bathrooms are usually two sizes: small and very tiny. In such a situation, when choosing a door, you have to focus first of all on the material, and only then, of the possible options, to choose the one that is best suited from the point of view of design.
