We bought this toilet seat with a Duravit Architect wall mounted toilet brand new from a private seller who did not use them in their project due to change of design.
Both items were new and unused. I was told that the seat is Tavistock however I can see any writing on it- so I can’t verify that.
We bought the pair as we wanted the Duravit Architect and which we installed with a Brindell seat… so this one was never used.
This is the best and most accurate (honest) description to the item I can give.
