What kind of bathroom brand is the best for a five-star hotel, the high-end one?

If it is TOTO, Kohler, American Standard, Le Jia, etc. As long as you have seen the bathroom brands in TV advertisements, those brands will basically not appear in the top five-star hotels, because these brands are not high-end, but only mid-range ...

Recommend several top high-end brands to you:

German Dornbach

Duravit, Germany

Villeroy & Germany; Boch

American hot springs

Lao Fen Swiss
