OMG! They are fabulous. I think it's just a matter of adjusting yourself to the new size. I just finished remodeling my bathroom and I chose the sinks which are about the same size as yours. I wondered if they would look too small but I love them. You want larger for functionality? You're not going to be washing your dog in there, are you?

If u put a drop in sink into the existing cutout the usable bowl will end up being smaller then what u have.....I would stick with what u have.....also your options may be limited because you will have to conform to the existing cut out

I like it too...waited a long time. Yessssss, water gets all over the place. I wanted the absolute black granite, knowing I was going to have to clean them often and wipe up the water marks. However, I still love it. I put a Carrara marble herringbone on the tub/shower surround (no glass closure) but I take a few minutes to wipe the whole shower dry after each use. I wanted these high maintenance finishes, so I'm willing to take care of them. I don't think your sink is smaller than mine. I'll measure if you would like. I think photos are sometimes distorted.

@jmcivettini what is the width of these sinks? How have you found them to be after more use?
