The faucet looks like a Rohl which comes with many different finishes and you can get it with a cross handle. Here's an example: Rohl A1419XC-2 Country Bath Low Lead Bridge Bathroom Faucet with Pop-Up Drain and Swarovski Crystal Cross Handles

Newport Brass also has a similar one: Newport Brass 1691 Virginia Double Handle Widespread Lavatory Faucet with Metal Cross Handles (Low Lead Compliant)

The wallpaper is Farrow & Ball, the sconces are antique with custom shield shades, door handle is custom and faucet is Newport Brass. The paint color is a custom mix with glazing over it. We appreciate your interest in Tiffany Farha Design!

There is a beautiful little shop in Venice, Italy that make very similar sconces. It is right across the tiny bridge to the right if you are facing the front of the Bauer Hotel. I have been trying to find out the name of the shop since I saw it a couple of months ago.

Can you do a virtual tour of Venice?
