The Dolce Hanoi Golden Lake Hotel in Vietnam has opened with a twist that it hopes will attract guests with intimately expensive tastes: gold-plated bathtubs, basins and even toilets, all housed behind a massive golden exterior. The hotel costed $200 million to construct with a 24-carat plating across lobbies, an infinity pool and rooms with even cutlery, cups, shower heads and toilet seats receiving the golden treatment.
