Mr. Zehetbauer says his girlfriend complains that the door on the powder room on the main level is made of glass ("I tell her it's frostedglass, " he said).
Couches and chairs have been re-covered, while polished marble and tidied-up fixtures give the bathrooms a more au courant look (the outdated sliding frosted-glass tub doors were mercifully removed).
It is even rarer to find an intact glass bottle (the older it is, the more completely frosted over) or Roman Samian ware, so it is a thrill when someone finds a piece.
