Have a Duravit Starck 3 2-piece toilet 2105010000 Hinges that hold the seat and cover are broken. Where are these hinges available?

Unfortunately you won't find a universal replacement part to work with this seat which you would commonly find at your local hardware store. I've looked through the Durovit site and could not find a parts catalog. Try using the find retailer option on the manufacturers site and if there isn't a retailer in your area contact the manufacturer directly to see if they supply parts for their seats. I'm guessing they don't and you would likely have to purchase a new seat.
