We purchased 7 of these for each the bathrooms in the home we just built. They look absolutely beautiful and very elegant but the pros stop there!! 
1. There is not a day that at least 1 hasn't been stopped up.
2. We live in the desert and the water on these is constantly running.
3. 3 if them have overflowed without a known clog flooding our entire master bedroom and our upstairs guest room causing thousands of $$ in damage. DO NOT BUY. We are currently  looking into replacing all 7 as it may very well be less expensive in the long term! SO DISAPPOINTING!!
