We absolutely love our trough sink. We drop mounted it onto a granite counter top.  It was perfect for bathing our newborn rather than kneeling into the tub.  We purchased a pop-up drain separately for it which meant that the sink and drain together cost more than the bathtub and shower surround... but it was a beautiful splurge.  We are very pleased with how it all turned out.  I will probably purchase the smaller version for our master bath remodel.
