Library furnishings

Rumours have abound about the extravagant furnishings in the library.  Two persistent  items have been:

• The chairs, supposedly $5k for Knoll Womb chairs.  Gee, they could have gotten fakes for only $800.
• The sinks, supposedly $5k for a pair like this one. 

I certainly feel cleaner using a sink like that.  I wonder how much these would have been.
