I am pretty sure about this one.
And if found in the bathroom,
Pericoma or
Ulomyia are not very likely. These bigger (4 mm) species mostly occur here in gardens and woods. I was mislead by the excellent quality of the picture ;). I only manage to make such detailed photos from the mentioned bigger species. The very tiny ones I also find often in the house, but I mostly see them only as "flying spots"... B)

OK let me clarify this issue. Drain fly is not a single species. It is any Psychodidae that thrives in the drainage of toilets, etc. There are several species, most are indistinct and are within Psychoda and Tinearia. These are greyish small midges, which hold their wings in a rooflike fashion. In addition Clogmia albopunctata also often occurs as a drain fly. This is a much larger species, among the largest Psychodids. (Sometimes placed within Telmatoscopus.) The males (seen rarely) and the females are somewhat different, and can be distinguished based on the photos.
Interestingly Clogmia albopunctata is not on the Hungarian list, although this is a very abundant fly everywhere I go here. This indicates that this midge has spread in recent decades, when the Hungarian Psychodidae expert was not active any more.
