Just to add my experience here, I remember my DD going through a short phase like this. After she refused to get into the bath, I stripped naked and I just plopped myself in the bath first. Of course she was shocked and giggling at that point,and I begged her to join me (she was about 2 at the time). She did get in with me, but when we were finished, I pulled the button up to start to drain the tub and noticed that was when she started to become upset again. Don't know if it was the loud gurgling, sucking sort of noise that the drain makes, or if she thought she was going to be sucked down the drain itself. I remember pulling her out of the tub and we just kneeled there together all dripping watching the water go down until it makes that funnel shape and I kept putting my finger in the funnel, and then she wanted to put her finger in the funnel shape. I assured her that the drain was much too small and not even our fingers could really go "down there". I never actually asked her if she was afraid of that either. It probably took about two weeks of bathing together for her to "grow out of it". You never know what freaks them out--could be the noise, fear of going down the drain, just too, too cold in the bathroom in the winter, could be any number of things. Hang in there Stressy!
