We're bathing our DD in a rectangular plastic container, nothing fancy. It fits on the benchtop, which a normal baby bath wouldn't. When she grows out of it we'll move to bathing her in the normal bath, I guess.

Best baby bath I've seen, but I haven't seen one in Australia like it (not that I've hunted hard or anything), was just designed to sit in the normal big bath, but it had a plug in the bottom so you could drain the water out easily.
