I never knew what a 'hip bath' was. In deMille's "Dance of Death", she says on page 91 that the married daughter of Andrew Jennings (Mrs. Dwight Waring) was selling Jennings' house and, in the attic, was found a collection of Lizzie Borden things Andrew Jennings had saved, but put in a hip bath with "summer shutters and awnings" covering the lot up.
The hip bath is described in deMille as a "child's tin bathtub".
There is a photo of a Victorian hip bath on this link that makes sense that Jennings' may have looked something like this:
Maybe the hip bathroom just meant that it was what in todays language would be called the "in" thing, you know the modern bathroom. Just my guess. Do like the picture of the tub. Thanks for the photo.
