This is a basic one that's the right size to replace our old 24"x18"x32" block vanity, was in stock at the store for easy pickup, and it has the layered square styling to match the bathtub, but when we set it up it still jutted out into the narrow space between the walls and was a hazard to the kids:

Here's the one that I really wanted, from Kohler. 18" deep, a full 24" wide, lots of top surface area, a sexy truncated oval shape. The side profile, including with the pedestal, is an absolute work of art. Sadly, Lisa felt that it wasn't round enough, and I made the mistake of mentioning that it was a little taller than our old sink.

So, looking through other options at Lowes, there were a few round sinks. This one was too small, it has to be close enough to the 24" width so that the original medicine cabinet doesn't look ridiculous. Also, the stumpy pedestal is just stupid looking:

This Crane design is a nice oval, but 20" deep is way too big!

So I very much liked this design from Crane, but I think that with the pedestal it was "too tall". Plus somebody online reviewed it as not being level although that could have just been installation.

Here are a few more Khol's options. This one was the right dimensions but just looked ridiculous with it's bulbous shape:

The width and depth on this Kohler alternative are right, but it wasn't unpointy enough for Lisa, it's ridiculously tall, and looks ugly from the side.
