Sorry just don't get it at all, apart from personal privacy issues, if there is no basin/sink in the toilet then surely germs can be spread? So have I got this right? to use the shower you need to get undressed in the cabin, then after you have used the shower you have to go back in the cabin to dry & get dressed do make up? To use the toilet you are in a glass cabinet not separated from the main cabin? I don't know about building regulations but I suspect these cabins would be illegal on land for housing. I am astonished.
