I have seen a few photo on this web site where people used a small towel bar on the false drawer front under each sink and hung the towel there.

You can search the bathroom photos here for more ideas.

I thought of that but I don't like that it will interfere with opening and closing the cabinet door.

would you ever consider a small portable one in between the 2 sinks on the counter or what about a towel rack on the left side I love the vanity by the way

I did buy one actually, but returned it. Hand towels are too long and drape on countertop. I'm trying to find fingertip towels in the color I'm looking for. Found Canterbury blue towels in target, but they don't make a fingertip towel

I always like to see what carolins suggests.

I went to Houzz Products, and entered "towel bar(s)" into the search box. There are more than 1,000 photos in this category. I tried to select a variety of different shapes. The style will not necessarily match your bathroom.

I would put it on the side like this!

I like the third pic of Carolins with the towel between the mirrors - looks good and very handy

If you have room do this

I like it between the mirrors too .... but the idea of placing it on the false drawer - gets in the way of the door opening - why not place it on the actual door, near the top.

I like both the small bars between mirrors or two towel rings between the mirrors

On the right side, place it on the side of towel tower. On the left, the side of the vanity. They need not be symmetrically positioned because the cabinet configuration in asymmetrical. This will keep the focal mirror wall clean and clutter free and the counter tops as well. I would not consider placing them on any part of the front facade of the cabinetry. Let us know what you decide.... Good Luck!

I like it on the false fronts too. I understand about it blocking cabinet access, but how often are you really in there anyway? Isn't it mostly for storage. Probably everyday things are in the drawers?
