In a house tour of a sleek, sterile “contemporary family apartment in Warsaw, Poland“, with no evidence of human life, we learned that “the bathroom IN the master bedroom is enclosed in black framed glass panels, which helps the small room from appearing closed off.”
…And allows the person lying in bed to witness their partner…
…well, you can imagine….
…(think of all the things you do in a bathroom that you prefer to do in private…)
Probably a bit much but most of us share bathroom space simultaneously. You just don’t look!
