It is a beautiful pairing and the sink will get plenty of compliments. I have had the sink and mirror for about 4 years now. It went into a small bathroom for a remodel.
U shaped towel bars are not very sturdy at all. I used this in a vacation rental and I had to have the u-shaped bars removed and another type of sturdy bar had to be installed to keep the sink sturdy. If you are using for a powder room with plenty of room, you should have no problems.
