Under-mount basins and wall mixers make cleaning a breeze and keep most of the splash off the taps.
One wipe over the top and your done. Only down-side is, the wall mixer costs on-average $100 more than a top-mount mixer, the plumber charges $200-$300 extra to install them and the stonemason charges an extra $180 for cutting and polishing the opening for the basin. Total cost around $550 extra per basin. For me, it is a must, but as always, your budget will come into play.
