I would think about what I'm using those sinks for.

I have a small sink in my guest bath, and it's fine there. But, for a main bathroom, will that sink be used to bathe babies... for someone to wash their hair...sweaters, etc.? It would be nice to have at least one set of larger sinks for those times you need to wash something other than your hands!

This is also one reason I'm not a huge fan of double sinks, especially in your 5 foot long counter. I like to have counter space (think changing a baby- guest placing make-up bags, clothes, etc). But, it's what works best for your lifestyle. Saving a few bucks here is not worth it if you'd rather have a larger sink.

I agree with raehelen that in the smaller counter I would rather have one larger off-center sink with a larger area of countertop to one side. Its hard to say whether that would work for you without more information.

raehelen--Thank you for the suggestion of thinking the use of the sink first! My current drop-in sink has such a large footprint but so little space inside the bowl that it never even occur to me to use it for anything other than washing hands and face :-(

After reading your post, I went out to local LOWE's to study different sinks and found out they have Kohler Bancroft(17X14 insde)on clearance sale, so I grabbed 4 at a price better than the no-name sink. Now I just have to figure out the difference between Bancroft and Caxton and whether Bancroft is good:-) What do you know about them?

palimpsest--I agree with you and raehelen that I would be better off with a single sink in the smaller bathroom. But this was the builder's set-up. To change to a single sink I probably has to change the base cabinet, that's too much trouble for a guest bathroom that was not used much at all. At least by using undermount sink, I will gain a few inches of counter space. .

I don't think that there is any quality difference between Kohler's Caxton and Bancroft sinks. I think it is just styling. The Bancroft has a ridge around the circumference and the Caxton is plain. The Bancroft one was designed to complement the Bancroft line (toilet, tub, etc.) and the Caxton goes with anything. 17" by 14" is a standard size. I think you'd be happy with either one.

astridh-- Thank you for commenting! I did notice Bancroft sink has a ridge. Do you think it will be very obvious to people that styles do not match? (I haven't planned to change the toilet at this moment) Do people actually pay attention to the styles of toilet? I never did :-(
