Another option is having two towel bars on the sides which is practical as this is a tiny bath off of a basement room that will be used as a bedroom. But I don't know...seems more institutional instead of sophisticated and more streamlined.

Here is a link that might be useful: Sapho sink with towel bars on the sides

I don't have that sink so I can't answer about the depth, but I prefer the look of the one with towel bars on the sides as opposed to the middle. The towel bar in the middle looks almost like some kind of grab bar or something. and I don't think I'd want to brush against the hand-drying towel (either lint gets on my clothes, or if I've been working outside then dirt gets on the towel).

Good points, Engineer Chic. I think I like the sink with the "grab bar" because the bowl itself is slimmer and the deck is wider. It seems more modern. Sigh...I have to give it some more fautl.

Overstock has a great many vanities with towel bars like that. You might want to read around in the reviews there to see if anyone mentions it being a problem.

Is the "grab bar" something you can install or leave off? If it's an optional add-on (something that hooks into hidden holes or clips) then you could consider getting the sink you like & just putting a towel bar on the wall, no?
