We're choosing a new tub for our master bath remodel. We have room for and can choose either free-standing or a tub with a deck surround. If we choose one that will have a deck surround, then we have to choose drop-in or under-mount. I was looking at some pictures online and it seems like under-mounting a tub would make it less comfortable because when leaning you head back you would hit the edge of the stone surround. With drop in it seems like your head would rest on the tub's edge, so the key would be to choose one with a comfy edge. Thoughts? Experience?
