Rachael, if it is any consolation, the all time fave bath toy for my children is an old potato masher. Go figure!

However, we were recently given a cool "proper" bath toy......a mesh bag of foam letters and numhers that stick to the bathroom tiles? I am not sure where they came from as they were a gift, but they are really fun.......I have a feeling I may have seen them on the Identity Direct website......
