Hello! According to the dictionary, 'banheiro' has got several meanings: http://www.infopedia.pt/lingua-portuguesa/banheiro I'm pretty sure that Portugueses do not use meanings 5) [I have just heard 'banheira'] and 6). But I'm not so sure if its usage with meaning 2) is contemplated (just out of curiosity, in Italian we call 'bagnino' someone defined by 2) Moreover, what do they mean with 4)? Thanks!!!
